Accounting Policies [Abstract]
Description of Company and Significant Accounting Policies	Description of Company and Significant Accounting Policies KBR, Inc., a Delaware corporation, was formed on March 21, 2006 and is headquartered in Houston, Texas. KBR, Inc. and its wholly owned and majority-owned subsidiaries (collectively referred to herein as "KBR", "the Company", "we", "us" or "our") is a global provider of differentiated, professional services and technologies across the asset and program life-cycle within the government services and hydrocarbons industries. Our capabilities include highly-specialized engineering services, mission and logistics support solutions, technology licensing, consulting, procurement, construction, construction management, program management, operations, maintenance and other support services to a diverse customer base, including domestic and foreign governments, international and national oil and gas companies, independent refiners, petrochemical producers, fertilizer producers and manufacturers. Principles of Consolidation Our condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR and our wholly owned and majority-owned subsidiaries and VIEs of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 9 to our condensed consolidated financial statements for further discussion on our equity investments and VIEs. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation on the condensed consolidated statements of operations, condensed consolidated balance sheets and the condensed consolidated statements of cash flows. We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures. Use of Estimates The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Areas requiring significant estimates and assumptions by our management include the following: • project revenues, costs and profits on engineering and construction contracts, including recognition of estimated losses on uncompleted contracts • project revenues, award fees, costs and profits on government services contracts • provisions for uncollectible receivables and client claims and recoveries of costs from subcontractors, vendors and others • provisions for income taxes and related valuation allowances and tax uncertainties • recoverability of goodwill • recoverability of other intangibles and long-lived assets and related estimated lives • recoverability of equity method and cost method investments • valuation of pension obligations and pension assets • accruals for estimated liabilities, including litigation accruals • consolidation of VIEs • valuation of share-based compensation • valuation of assets and liabilities acquired in business combinations In accordance with normal practice in the construction industry, we include in current assets and current liabilities amounts related to construction contracts realizable and payable over a period in excess of one year. If the underlying estimates and assumptions upon which the financial statements are based change in the future, actual amounts may differ from those included in the accompanying condensed consolidated financial statements. Adoption of New Accounting Standards Compensation . Effective January 1, 2017, we adopted ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting which was issued by the FASB on March 31, 2016. This ASU is intended to simplify several aspects of the accounting for share-based payment transactions including (a) the income tax consequences, (b) classification of awards as either equity or liabilities, and (c) classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. The adoption of ASU 2016-09 did not have a material impact on our financial statements. Additional Balance Sheet Information Other Current Liabilities The components of "other current liabilities" on our condensed consolidated balance sheets as of March 31, 2017 and December 31, 2016 are presented below: March 31, December 31, Dollars in millions 2017 2016 Reserve for estimated losses on uncompleted contracts (a) $ 42 $ 63 Retainage payable 49 47 Income taxes payable 55 55 Restructuring reserve 15 30 Taxes payable not based on income 13 14 Value-added tax payable 17 16 Insurance payable 15 14 Dividend payable 12 12 Other miscellaneous liabilities (b) 34 41 Total other current liabilities $ 252 $ 292 (a) See Note 2 to our condensed consolidated financial statements for further discussion on significant reserves for estimated losses on uncompleted contracts. (b) Included in "other miscellaneous liabilities" is deferred rent of $4 million as of March 31, 2017 and December 31, 2016 . Other Liabilities Included in "other liabilities" on our condensed consolidated balance sheets as of March 31, 2017 and December 31, 2016 is noncurrent deferred rent of $102 million and $103 million , respectively. Also included in "other liabilities" is a payable to our former parent of $19 million

Business Segment Information

Business Segment Information	3 Months Ended

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information We are organized into three core business segments and two non-core business segments. Our three core business segments focus on our core strengths in technical services relating to government services, technology and consulting, and engineering and construction. Our two non-core business segments are our Non-strategic Business segment, which includes businesses we intend to exit upon completion of existing contracts because they are no longer a part of our future strategic focus, and "Other", which includes our corporate expenses and general and administrative expenses not allocated to the other business segments. Each business segment reflects a reportable segment led by a separate business segment president who reports directly to our CODM. Our business segments are described below. Government Services. Our GS business segment provides full life-cycle support solutions to defense, space, aviation and other programs and missions for government agencies in the U.S., U.K. and Australia. As program management integrator, KBR covers the full spectrum of defense, space, aviation and other government programs and missions from research and development; through systems engineering, test and evaluation, systems integration and program management; to operations support, maintenance and field logistics. Our recent acquisitions, as described in Note 3 to our condensed consolidated financial statements, have been combined with our existing U.S. operations within this business segment and operate under the single "KBRwyle" brand. Technology & Consulting. Our T&C business segment combines proprietary KBR technologies, knowledge-based services and our three specialist consulting brands, Granherne, Energo and GVA under a single customer-facing global business. This segment provides licensed technologies, know-how and consulting services to the hydrocarbons value chain, from wellhead to crude refining and through refining and petrochemicals to specialty chemicals production. In addition to sharing many of the same customers, these brands share the approach of early and continuous customer involvement to deliver an optimal solution to meet the customers' objectives through early planning and scope definition, advanced technologies, and project life-cycle support. Engineering & Construction. Our E&C business segment provides comprehensive project and program delivery capability globally. Our key capabilities leverage our operational and technical excellence as a global provider of EPC for onshore oil and gas; LNG/GTL; oil refining; petrochemicals; chemicals; fertilizers; offshore oil and gas (shallow-water, deep-water and subsea); floating solutions (FPUs, FPSO, FLNG & FSRU); and maintenance services (via the “Brown & Root Industrial Services” brand). Non-strategic Business. Our Non-strategic Business segment represents the operations or activities that we intend to exit upon completion of existing contracts. Other. Our Other business segment includes corporate expenses and general and administrative expenses not allocated to the business segments above and any future activities that do not individually meet the criteria for segment presentation. The following table presents revenues, gross profit (loss), equity in earnings of unconsolidated affiliates, and operating income (loss) by reporting segment.

These include, but are not limited to, the availability and costs of resources (such as labor, materials and equipment), productivity and weather, and for unit rate and construction service contracts, the availability and detail of customer supplied engineering drawings. With a portfolio of more than one thousand contracts, we sometimes realize both lower and higher than expected margins on projects in any given period. We recognize revisions of revenues and costs in the period in which the revisions are known. This may result in the recognition of costs before the recognition of related revenue recovery, if any. Changes in project-related estimates by business segment, which significantly impacted operating income during the periods presented, are as follows: Government Services There were no significant changes to contract estimates during the three months ended March 31, 2017 within our GS Business segment. During the three months ended March 31, 2016 , we recognized a $15 million favorable change to gross profit related to the approval of a change order on a road construction project in the Middle East. Engineering & Construction There were no significant changes to contract estimates during the three months ended March 31, 2017 within our E&C business segment. During the three months ended March 31, 2016 , we recognized unfavorable changes in estimates of losses of $30 million , on an EPC ammonia project in the U.S. primarily due to unforeseen costs related to the mechanical failure of a vendor supplied compressor and pumps that occurred during commissioning. The project was transferred to the customer in October 2016. Included in the reserve for estimated losses on uncompleted contracts, which is a component of "other current liabilities" on our condensed consolidated financial statements, is $2 million and $3 million as of March 31, 2017 and December 31, 2016 , respectively, related to this project. Revenues, gross profit, and segment operating income for the three months ended March 31, 2016 include $20 million related to a favorable change in estimate as a result of reaching a settlement on close out of a LNG project in Africa. During 2016 , we experienced weather delays and forecast construction productivity rates less than previously expected on a downstream EPC project in the U.S. These issues delayed completion of the project until 2018, which resulted in additional estimated costs to complete and caused this project to become a loss project in the fourth quarter of 2016 . There were no significant changes in estimated losses on this project during the three months ended March 31, 2017 . Included in the reserve for estimated losses on uncompleted contracts is $26 million and $35 million as of March 31, 2017 and December 31, 2016 , respectively, related to this project. The EPC project was 69% complete as of March 31, 2017 . Our estimated loss at completion represents our best estimate based on current information. Actual results could differ from the estimates we have used to account for this project as of March 31, 2017 . Non-strategic Business There were no significant changes to contract estimates during the three months ended March 31, 2017 within our Non-strategic Business segment. During the three months ended March 31, 2016 , we recognized unfavorable changes in estimates of losses on a power project of $5 million , primarily due to increases in subcontractor costs to complete the project as a result of poor productivity from subcontractors. The project has completed performance testing and in April 2017, care, custody and control of the project were transferred to the customer. Included in the reserve for estimated losses on uncompleted contracts is $5 million and $14 million as of March 31, 2017 and December 31, 2016

Business Combinations [Abstract]
Mergers, Acquisitions and Dispositions Disclosures [Text Block]	Acquisitions, Dispositions and Other Transactions Wyle and Honeywell Technology Solutions Inc. Acquisitions During the third quarter of 2016, we acquired 100% of the equity interests of Wyle and 100% of the outstanding common stock of HTSI, which we converted into KTS. The aggregate consideration paid for these acquisitions was $900 million , which was funded with $700 million in advances on our Credit Agreement and available cash on-hand. See Note 11 to our condensed consolidated financial statements for information related to our Credit Agreement. Certain data necessary to complete the purchase price allocation of the Wyle acquisition is not yet available and primarily relates to final tax returns that provide the underlying tax basis of assets and liabilities. The purchase price allocation for the KTS acquisition was completed during the three months ended March 31, 2017. These acquisitions are reported within our GS business segment. The following table summarizes the consideration paid for these acquisitions and the fair value of the assets acquired and liabilities assumed as of the acquisition date. Dollars in millions Wyle KTS Fair value of total consideration transferred $ 623 $ 280 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash 10 — Trade receivables, net 47 29 CIE 98 93 Prepaids and other current assets 4 5 Total current assets 159 127 Property, plant and equipment, net 10 7 Intangible assets 141 70 Deferred income taxes — 8 Total assets 310 212 Accounts payable 59 23 BIE — 5 Other current liabilities 47 35 Total current liabilities 106 63 Deferred income taxes 52 — Other liabilities 12 — Total liabilities 170 63 Goodwill $ 483 $ 131 The acquired Wyle and KTS businesses contributed $170 million and $129 million of revenues and $13 million and $9 million of gross profit, respectively, for the three months ended March 31, 2017 . The following supplemental pro forma condensed consolidated results of operations assume that Wyle and KTS had been acquired as of January 1, 2015. The supplemental pro forma financial information was prepared based on the historical financial information of Wyle and KTS and has been adjusted to give effect to pro forma adjustments that are directly attributable to the transaction. The pro forma amounts reflect certain adjustments to amortization expense and interest expense associated with the portion of the purchase price funded by $700 million in advances on our Credit Agreement and also reflect adjustments to 2016 results to exclude acquisition related costs as they are nonrecurring and are directly attributable to the transaction. The supplemental pro forma financial information presented below does not include any anticipated cost savings or expected realization of other synergies associated with the transactions. Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisitions occurred on January 1, 2015, nor is it indicative of future results of operations. Dollars in millions, except per share data Three Months Ended March 31, 2016 (Unaudited) Revenue $ 1,343 Net income attributable to KBR 54 Diluted earnings per share $ 0.38 Chematur Subsidiaries Acquisition On January 11, 2016, we acquired 100% of the outstanding common stock of three subsidiaries of Connell Chemical Industry LLC. The aggregate consideration paid for the acquisition was $25 million , less $2 million of acquired cash and other adjustments resulting in net cash consideration of $23 million . We recognized goodwill of $24 million arising from the acquisition. This acquisition is reported within our T&C business segment. New Investments UKMFTS project. In February 2016, we executed agreements to establish a new joint venture between KBR and Elbit Systems within our GS business segment, named Affinity. Affinity was awarded a service contract by a third party to procure, operate and maintain aircraft, and aircraft-related assets over an 18 -year contract period, in support of the UKMFTS project. KBR owns a 50% interest in Affinity. In addition, KBR owns a 50% interest in the two joint ventures, Affinity Capital Works and Affinity Flying Services, which provide procurement, operations and management support services under subcontracts with Affinity. During the first quarter of 2016, under the terms of the subordinated debt agreement between the partners and Affinity, we advanced our proportionate share, or $14 million , to meet initial working capital needs of the venture. We expect repayment on the advance and the associated interest over the term of the project. This amount is included in the "equity in and advances to unconsolidated affiliates" balance on our consolidated balance sheets as of March 31, 2017 and in "(advances to) payments from unconsolidated affiliates, net" in our consolidated statement of cash flows for the three months ended March 31, 2016 .

Cash and Cash Equivalents	Cash and Equivalents We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and equivalents include cash balances held by our wholly owned subsidiaries as well as cash held by joint ventures that we consolidate. Joint venture cash balances are limited to joint venture activities and are not available for other projects, general cash needs or distribution to us without approval of the board of directors of the respective joint ventures. We expect to use joint venture cash for project costs and distributions of earnings related to joint venture operations. However, some of the earnings distributions may be paid to other KBR entities where the cash can be used for general corporate needs.

Percentage-of-Completion Contracts	Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts and Billings in Excess of Costs and Estimated Earnings on Uncompleted Contracts Our CIE balances by business segment are as follows: March 31, December 31, Dollars in millions 2017 2016 Government Services $ 262 $ 271 Technology & Consulting 49 30 Engineering & Construction 103 115 Subtotal 414 416 Non-strategic Business — — Total $ 414 $ 416 Our BIE balances by business segment are as follows: March 31, December 31, Dollars in millions 2017 2016 Government Services $ 70 $ 76 Technology & Consulting 58 61 Engineering & Construction 290 388 Subtotal 418 525 Non-strategic Business 15 27 Total $ 433 $ 552 Unapproved change orders and claims The amounts of unapproved change orders and claims included in determining the profit or loss on contracts are as follows: Dollars in millions 2017 2016 Amounts included in project estimates-at-completion at January 1, $ 285 $ 104 Additions 133 23 Approved change orders (2 ) (28 ) Amounts included in project estimates-at-completion at March 31, $ 416 $ 99 Amounts recognized on a percentage-of-completion basis at March 31, $ 344 $ 75 Ichthys LNG project. A significant portion of the amounts disclosed above relate to our proportionate share of unapproved change orders and claims associated with our 30% ownership interest in the Ichthys JV which has contracted to perform the engineering, procurement, supply, construction and commissioning of onshore LNG facilities for a client in Darwin, Australia. The contract between the Ichthys JV and its client is a hybrid contract containing both cost-reimbursable and fixed-price (including unit-rate) scopes. The Ichthys JV has entered into commercial contracts with multiple subcontractors to execute various scopes of work on the project. Certain of these subcontractors have made contract claims against the Ichthys JV for recovery of costs and an extension of time in order to progress the works under the scope of their respective contracts due to a variety of issues related to changes to the scope of work, delays and lower than planned subcontractor productivity. In addition, the Ichthys JV has or is expected to incur incremental costs due to these circumstances. Some of these claims relate to cost-reimbursable work between the Ichthys JV and its client while other claims relate to fixed-price scopes of work, including unit-rate components. We believe any amounts paid or payable to the subcontractors in settlement of their contract claims related to cost-reimbursable scopes of work is an adjustment to the contract price under the reimbursable portion of the contract between the Ichthys JV and its client; however, the client has disputed these contract price adjustments. In order to facilitate the continuation of work under the contract while we work to resolve this dispute, the client has agreed to a contractual mechanism (“Deed of Settlement”) providing funding in the form of an interim contract price adjustment to the Ichthys JV for settlement of certain subcontractor claims related to cost-reimbursable scopes of work. The Ichthys JV has in turn settled these subcontractor claims relating to cost-reimbursable work which have been funded through the Deed of Settlement by the client. If the Ichthys JV does not resolve the claims under the Deed of Settlement with its client by December 31, 2020, it will be required to refund sums in excess of the final adjusted contract price with the client under the terms of the Deed of Settlement. We, along with our joint venture partners, are jointly and severally liable to the client for any amounts required to be refunded. If the negotiation does not lead to a timely settlement, the Ichthys JV may file for arbitration against the client to resolve these open reimbursable subcontractor claims prior to December 31, 2020. In addition, the Ichthys JV continues to pursue resolution of additional claims related to both the reimbursable and fixed-price portions of the contract which were not covered by the Deed of Settlement through direct negotiation with the client. There are also additional costs that have resulted in unfavorable changes to the estimated profit at completion for which the Ichthys JV continues to pursue recovery with the client. Together, these additional change orders, claims and additional costs have resulted in a reduction to our percentage of completion progress for the three months ended March 31, 2017 . In accordance with U.S. GAAP and our accounting policy for unapproved change orders and claims, without customer approval or equivalent persuasive evidence of recovery, we are limited on the amount of unapproved change orders and claims revenues that we can recognize for a specific claim in our estimate of revenue and profit at completion. The Ichthys JV intends to vigorously pursue negotiation and recovery of the gross claims against our client, which when approved or deemed probable of recovery under our accounting policies, could result in revenues and profit at completion in excess of what we have been able to recognize as of March 31, 2017. It is anticipated that these commercial matters may not be resolved in the near term. If these matters are not resolved for the amounts recorded, or to the extent the Ichthys JV is not successful in recovering amounts contractually due under the Deed of Settlement, it could have an adverse effect on our results of operations, financial position and cash flows. The Ichthys JV awarded a fixed-price subcontract for the design, construction and commissioning of a combined cycle power plant on the Ichthys JV site, which is pursuant to the Ichthys JV's fixed-price portion of its contract with the client. The subcontractor is a consortium consisting of a joint venture between UGL Infrastructure Pty Limited and CH2M Hill (the "UGL-CH2M Hill JV"), and General Electric and GE Electrical International Inc (collectively, the "Consortium"). On January 25, 2017, the Ichthys JV received Notice of Termination from the Consortium. The Ichthys JV has evaluated the cost to complete the Consortium’s work, which exceeds the subcontract value. The additional cost amounts, including probable claim revenue, have been included in the Ichthys JV's estimate to complete the Consortium's remaining obligation. The Ichthys JV believes the Consortium breached its contract and will pursue recourse against the Consortium to recover the additional amounts needed to complete the remaining work on the combined cycle power plant, inclusive of calling bank guarantees (bonds) and parent guarantees provided by the Consortium partners. Each of the Consortium partners has joint and several liability with respect to all obligations under the subcontract. We expect the Consortium to challenge the Ichthys JV's recourse actions. If the Ichthys JV is unsuccessful in recovering such costs, we would be responsible for our pro-rata portion of unrecovered costs. This could have a material adverse impact on the profit at completion of the contract and thus on our consolidated statements of operations, financial position and cash flow. Liquidated damages Some of our engineering and construction contracts have schedule dates and performance obligations that if not met could subject us to penalties for liquidated damages. These generally relate to specified activities that must be completed by a set contractual date or by achievement of a specified level of output or throughput. Each contract defines the conditions under which a customer may make a claim for liquidated damages. However, in some instances, liquidated damages are not asserted by the customer, but the potential to do so is used in negotiating or settling claims and closing out the contract. Any accrued liquidated damages are recognized as a reduction in revenues in our condensed consolidated statements of operations. It is possible that liquidated damages related to several projects totaling $10 million and $8 million at March 31, 2017 and December 31, 2016

Receivables [Abstract]
Claims Receivable	Claims and Accounts Receivable Our claims and accounts receivable balance not expected to be collected within the next 12 months was $122 million and $131 million as of March 31, 2017 and December 31, 2016 , respectively. Claims and accounts receivable primarily reflects claims filed with the U.S. government related to payments not yet received for costs incurred under various U.S. government contracts within our GS business segment. These claims relate to disputed costs or contracts where our costs have exceeded the U.S. government's funded value on the task order. Included in the amount is $83 million as of March 31, 2017 and December 31, 2016 , related to Form 1s issued by the U.S. government questioning or objecting to costs billed to them. See Note 13 of our condensed consolidated financial statements for additional discussions. The amount also includes $39 million and $48 million as of March 31, 2017 and December 31, 2016

Restructuring and Related Activities [Abstract]
Restructuring, Impairment, and Other Activities Disclosure [Text Block]	Restructuring In connection with our long-term strategic reorganization, we announced that beginning in the fourth quarter of 2014 we would undertake a restructuring, which would include actions such as reducing the amount of real estate we utilized and significantly reducing our workforce. There were additional actions undertaken in 2015 and 2016, including staff reductions to support current business levels. The employees affected by these reductions are eligible for separation benefits upon their expected termination dates which have occurred or are expected to occur through 2017. The table below provides a rollforward of one-time charges associated with employee terminations based on the fair value of the termination benefits. These amounts are included in "other current liabilities" on our condensed consolidated balance sheets. Dollars in millions Severance Accrual Balance at December 31, 2016 $ 8 Charges — Payments (4 ) Balance at March 31, 2017 $ 4 Balance at December 31, 2015 $ 19 Charges 5 Payments (7 ) Balance at March 31, 2016 $ 17

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments And Variable Interest Entities	Equity Method Investments and Variable Interest Entities We conduct some of our operations through joint ventures which operate through partnership, corporation, undivided interest and other business forms and are principally accounted for using the equity method of accounting. Additionally, the majority of our joint ventures are VIEs. The following table presents a rollforward of our equity in and advances to unconsolidated affiliates: March 31, December 31, Dollars in millions 2017 2016 Beginning balance $ 369 $ 281 Equity in earnings of unconsolidated affiliates 9 91 Distribution of earnings of unconsolidated affiliates (a) (14 ) (56 ) Advances (receipts) (1 ) 1 Investments (b) — 61 Foreign currency translation adjustments 8 (8 ) Other — (8 ) Balance before reclassification $ 371 $ 362 Reclassification of excess distributions (a) — 12 Recognition of excess distributions (a) (2 ) (5 ) Ending balance $ 369 $ 369 (a) We received cash dividends in excess of the carrying value of one of our investments. We have no obligation to return any portion of the cash dividends received. We recorded the excess dividend amount as "deferred income from unconsolidated affiliates" on our condensed consolidated balance sheets and recognize these dividends as earnings are generated by the investment. (b) In 2016, investments included a $56 million investment in the Brown & Root Industrial Services joint venture and a $5 million investment in the EPIC joint venture. Unconsolidated Variable Interest Entities Generally, our maximum exposure to loss is limited to our equity investment in the joint venture and any amounts payable to us for services we provided to the joint venture reduced for any unearned revenues on the projects. On the Affinity joint venture, our maximum exposure to loss is limited to our proportionate share of any amounts required to fund future losses incurred by those entities under their respective contracts with the project company. On the Aspire Defence project, in addition to the maximum exposure to loss indicated in the table below, we have exposure to any losses incurred by the construction or operating joint ventures under their respective subcontract arrangements with the project company. Our exposure is, however, limited to our equity participation in these entities. The Ichthys JV executes a project that has both cost-reimbursable and lump sum components; in addition to the maximum exposure to loss indicated in the table below, we have an exposure to funding any future losses to the extent of our ownership percentage in the joint venture and to the extent any of our joint venture partners are unable to meet their obligations, as we have joint and several liability. Our maximum exposure to loss on the EBIC Ammonia plant reflects our 65% ownership of the development corporation which owns 25% of the company that consolidates the ammonia plant. We continue to monitor our investment in this joint venture as the profitability of its operations has been impacted by various challenges including restricted port access in Egypt to ship products to international customers. The following summarizes the total assets and total liabilities as reflected in our condensed consolidated balance sheets as well as our maximum exposure to losses related to our unconsolidated VIEs in which we have a significant variable interest but are not the primary beneficiary. March 31, 2017 Dollars in millions Total assets Total liabilities Maximum exposure to loss (a) Affinity project $ 12 $ 3 $ 12 Aspire Defence project $ 13 $ 104 $ 13 Ichthys LNG project $ 122 $ 28 $ 122 U.K. Road projects $ 32 $ 10 $ 32 EBIC Ammonia plant (65% interest) $ 33 $ 2 $ 22 December 31, 2016 Dollars in millions Total assets Total liabilities Maximum exposure to loss (a) Affinity project $ 12 $ 3 $ 12 Aspire Defence project $ 14 $ 107 $ 14 Ichthys LNG project $ 124 $ 33 $ 124 U.K. Road projects $ 30 $ 9 $ 30 EBIC Ammonia plant (65% interest) $ 34 $ 2 $ 22 (a) Excludes exposure to funding any future losses to the extent of our ownership percentage in the joint venture and joint and several liability to the extent any of our joint venture partners are unable to meet their obligations. Related Party Transactions We often provide engineering, construction management and other subcontractor services to our joint ventures and our revenues include amounts related to these services. For the three months ended March 31, 2017 and 2016 , our revenues included $27 million and $99 million , respectively, related to the services we provided to our joint ventures, primarily the Ichthys JV within our E&C business segment. Under the terms of an alliance agreement with our EPIC joint venture, EPIC provides certain pipe fabrication services to KBR. For the three months ended March 31, 2017 and 2016 , EPIC provided $2 million and $5 million , respectively of services to KBR under the agreement. Under the terms of our TSA with Brown & Root Industrial Services joint venture, we collect cash from customers and make payments to vendors and employees on behalf of the joint venture. For the three months ended March 31, 2017 and 2016 , we incurred approximately $2 million and $4 million , respectively, of reimbursable costs under the TSA. Amounts included in our condensed consolidated balance sheets related to services we provided to our unconsolidated joint ventures as of March 31, 2017 and December 31, 2016 are as follows: March 31, December 31, Dollars in millions 2017 2016 Accounts receivable, net of allowance for doubtful accounts (a) $ 17 $ 22 Costs and estimated earnings in excess of billings on uncompleted contracts (b) $ 1 $ 1 Billings in excess of costs and estimated earnings on uncompleted contracts (b) $ 34 $ 41 (a) Includes an $8 million and $11 million net receivable from the Brown & Root Industrial Services joint venture at March 31, 2017 and December 31, 2016 , respectively. (b) Reflects CIE and BIE primarily related to joint ventures within our E&C business segment as discussed above. Consolidated Variable Interest Entities We consolidate VIEs if we determine we are the primary beneficiary of the project entity because we control the activities that most significantly impact the economic performance of the entity. The following is a summary of the significant VIEs where we are the primary beneficiary: Dollars in millions March 31, 2017 Total assets Total liabilities Gorgon LNG project $ 26 $ 59 Escravos Gas-to-Liquids project $ 8 $ 16 Fasttrax Limited project $ 59 $ 53 Dollars in millions December 31, 2016 Total assets Total liabilities Gorgon LNG project $ 28 $ 60 Escravos Gas-to-Liquids project $ 11 $ 22 Fasttrax Limited project $ 56 $ 50

Debt Disclosure [Abstract]
Debt and Other Credit Facilities	Debt and Other Credit Facilities Credit Agreement On September 25, 2015, we entered into a $1 billion , unsecured revolving credit agreement (the "Credit Agreement") with a syndicate of banks. The Credit Agreement is guaranteed by certain of the Company's domestic subsidiaries, matures in September 2020 and is available for cash borrowings and the issuance of letters of credit related to general corporate needs. Subject to certain conditions, we may request (i) that the aggregate commitments under the Credit Agreement be increased by up to an additional $500 million , and (ii) that the maturity date of the Credit Agreement be extended by two additional one-year terms. Amounts drawn under the Credit Agreement will bear interest at variable rates, per annum, based either on (i) the LIBOR plus an applicable margin of 1.375% to 1.75%, or (ii) a base rate plus an applicable margin of 0.375% to 0.75%, with the base rate equal to the highest of (a) reference bank’s publicly announced base rate, (b) the Federal Funds Rate plus 0.5%, or (c) LIBOR plus 1%. The amount of the applicable margin to be applied will be determined by the Company’s ratio of consolidated debt to consolidated EBITDA for the prior four fiscal quarters as defined in the Credit Agreement. The Credit Agreement provides for fees on letters of credit issued under the Credit Agreement at a rate equal to the applicable margin for LIBOR-based loans, except for performance letters of credit, which are priced at 50% of such applicable margin. KBR pays an annual issuance fee of 0.125% of the face amount of a letter of credit and pays a commitment fee of 0.225% to 0.25%, per annum, on any unused portion of the commitment under the Credit Agreement based on the Company's consolidated leverage ratio. As of March 31, 2017 , there were $39 million in letters of credit outstanding. As a result of the Wyle and KTS acquisitions discussed in Note 3 to our condensed consolidated financial statements, we funded $700 million of acquisition consideration with borrowings under our Credit Agreement, of which $650 million remains outstanding as of March 31, 2017 . Interest expense for the three months ended March 31, 2017 was $4 million . The Credit Agreement contains customary covenants as defined by the agreement which include financial covenants requiring maintenance of a ratio of consolidated debt to a rolling four-quarter consolidated EBITDA not greater than 3.5 to 1 and a minimum consolidated net worth of $1.2 billion plus 50% of consolidated net income for each quarter beginning September 30, 2015 and 100% of any increase in shareholders’ equity attributable to the sale of equity interests, but excluding any adjustments in shareholders' equity attributable to changes in foreign currency translation adjustments. In December 2016, we obtained an amendment to the debt to EBITDA financial covenant to eliminate the impact, for certain periods and subject to certain dollar limits, of previously recorded project losses attributed to an EPC ammonia project and a power project in the U.S. The amendment also amends the maximum ratio of consolidated debt to consolidated EBITDA to 3.25 to 1 effective for periods after December 31, 2017. As of March 31, 2017 , we were in compliance with our financial covenants. The Credit Agreement contains a number of other covenants restricting, among other things, our ability to incur additional liens and indebtedness, enter into asset sales, repurchase our equity shares and make certain types of investments. Our subsidiaries are restricted from incurring indebtedness, except if such indebtedness relates to purchase money obligations, capitalized leases, refinancing or renewals secured by liens upon or in property acquired, constructed or improved in an aggregate principal amount not to exceed $200 million at any time outstanding. Additionally, our subsidiaries may incur unsecured indebtedness not to exceed $200 million in aggregate outstanding principal amount at any time. We are also permitted to repurchase our equity shares, provided that no such repurchases shall be made from proceeds borrowed under the Credit Agreement, and that the aggregate purchase price and dividends paid after September 25, 2015, does not exceed the Distribution Cap (equal to the sum of $750 million plus the lesser of (1) $400 million and (2) the amount received by us in connection with the arbitration and subsequent litigation of the PEP contracts as discussed in Note 14 to our condensed consolidated financial statements). As of March 31, 2017 , the remaining availability under the Distribution Cap was approximately $641 million . Nonrecourse Project Debt Fasttrax Limited, a joint venture in which we indirectly own a 50% equity interest with an unrelated partner, was awarded a concession contract in 2001 with the U.K. MoD to provide a Heavy Equipment Transporter Service to the British Army. Under the terms of the arrangement, Fasttrax Limited operates and maintains 91 HETs for a term of 22 years. The purchase of the HETs by the joint venture was financed through two series of bonds secured by the assets of Fasttrax Limited and a bridge loan totaling approximately £84.9 million (approximately $120 million at the exchange rate on the date of the transaction). The secured bonds are an obligation of Fasttrax Limited and are not a debt obligation of KBR as they are nonrecourse to the joint venture partners. Accordingly, in the event of a default on the notes, the lenders may only look to the assets of Fasttrax Limited for repayment. The bridge loan of approximately £12.2 million (approximately $17 million at the exchange rate on the date of the transaction) was replaced when the joint venture partners funded their equity and subordinated debt contributions in 2005. The secured bonds were issued in two classes consisting of Class A 3.5% Index Linked Bonds in the amount of £56 million (approximately $79 million at the exchange rate on the date of the transaction) and Class B 5.9% Fixed Rate Bonds in the amount of £16.7 million (approximately $24 million at the exchange rate on the date of the transaction). Semi-annual payments on both classes of bonds commenced in March 2005 and will continue through maturity in 2021. The subordinated notes payable to each of the partners initially bear interest at 11.25% increasing to 16%

Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes The effective tax rate was approximately 25% for the three months ended March 31, 2017 and 2016 . Our estimated annual effective tax rate for 2017 is 25% , which is lower than the U.S. statutory rate of 35% primarily due to the rate differential on our foreign earnings as well as non-controlling interests and equity earnings. Our estimated annual effective rate is subject to change based on the actual jurisdictions where our 2017 earnings are generated. The valuation allowance for deferred tax assets as of March 31, 2017 and December 31, 2016 was $539 million and $542 million , respectively. The valuation allowance decreased by $3 million in the three months ended March 31, 2017 . There was no change in the valuation allowance in the three months ended March 31, 2016 . The valuation allowance is primarily related to foreign tax credit carryforwards, foreign and state net operating loss carryforwards and other deferred tax assets that, in the judgment of management, are not more-likely-than-not to be realized. The reserve for uncertain tax positions included in "other liabilities" and "deferred income taxes" on our condensed consolidated balance sheets as of March 31, 2017 and December 31, 2016 was $262 million and $261 million , respectively. The net increase in the uncertain tax position was $1 million for the three months ended March 31, 2017 and 2016

U.S. Government Matters

U.S. Government Matters	3 Months Ended

United States Government Contract Work [Abstract]
U.S. Government Matters	U.S. Government Matters We provide services to various U.S. governmental agencies, which include the U.S. DoD and the Department of State. We may have disagreements or experience performance issues on our U.S. government contracts. When performance issues arise under any of these contracts, the U.S. government retains the right to pursue various remedies, including challenges to expenditures, suspension of payments, fines and suspensions or debarment from future business with the U.S. government. The negotiation, administration and settlement of our contracts are subject to audit by the DCAA. The DCAA serves in an advisory role to the DCMA, and the DCMA is responsible for the administration of the majority of our contracts. The scope of these audits include, among other things, the validity of direct and indirect incurred costs, provisional approval of annual billing rates, approval of annual overhead rates, compliance with the FAR and CAS, compliance with certain unique contract clauses and audits of certain aspects of our internal control systems. Based on the information received to date, we do not believe the completed or ongoing government audits will have a material adverse impact on our results of operations, financial position or cash flows. Legacy U.S. Government Matters Between 2002 and 2011, we provided significant support to the U.S. Army and other U.S. government agencies in support of the war in Iraq under the LogCAP III contract. We continue to support the U.S. government around the world under the LogCAP IV and other contracts. We have been in the process of closeout of the LogCAP III contract since 2011, and we expect the closeout process to continue through at least 2018. As a result of our work under LogCAP III, there are claims and disputes pending between us and the U.S. government which need to be resolved in order to close the contract. The closeout process includes resolving objections raised by the U.S. government through a billing dispute process referred to as Form 1s and MFRs. We continue to work with the U.S. government to resolve these issues and are engaged in efforts to reach mutually acceptable resolution of these outstanding matters. However, for certain of these matters, we have filed claims with the ASBCA or the COFC. We also have matters related to ongoing litigation or investigations involving U.S. government contracts. We anticipate billing additional labor, vendor resolution and litigation costs as we resolve the open matters. At this time, we cannot determine the timing or net amounts to be collected or paid to close out these contracts. Form 1s The U.S. government has issued Form 1s questioning or objecting to costs we billed to them primarily related to (1) our use of private security and our provision of containerized housing under the LogCAP III contract discussed above and (2) our provision of emergency construction services primarily to U.S. government facilities damaged by Hurricanes Katrina and Wilma, under our CONCAP III contract with the U.S. Navy. As a consequence of the issuance of the Form 1s, the U.S. government has withheld payment to us on outstanding invoices, pending resolution of these matters. In certain cases, we have also withheld payment to our subcontractors related to pay-when-paid contractual terms. The U.S. government issued Form 1s, questioning $173 million of billed costs as of March 31, 2017 and December 31, 2016 . They had previously paid us $90 million as of each period related to our services on these contracts and the remaining balance of $83 million for each period is included in “claims and accounts receivable" on our condensed consolidated balance sheets. In addition, we have withheld $26 million from our subcontractors at March 31, 2017 and December 31, 2016 , related to these questioned costs. While we continue to believe that the amounts we have invoiced the U.S. government are in compliance with our contract terms and that recovery is probable, we also continue to evaluate our ability to recover these amounts as new information becomes known. As is common in the industry, negotiating and resolving these matters is often an involved and lengthy process, which sometimes necessitates the filing of claims or other legal action as discussed above. Concurrent with our continued negotiations with the U.S. government, we await the rulings on the filed claims. We are unable to predict when the rulings will be issued or when the matters will be settled or resolved with the U.S. government. As a result of the Form 1s, and claims discussed above as well as open audits, we have accrued a reserve for unallowable costs at March 31, 2017 and December 31, 2016 of $64 million as a reduction to "claims and accounts receivable" and in "other liabilities" on our condensed consolidated balance sheet. Investigations, Qui Tams and Litigation The following matters relate to ongoing litigation or federal investigations involving U.S. government contracts. Many of these matters involve allegations of violations of the FCA, which prohibits in general terms fraudulent billings to the government. Suits brought by private individuals are called "qui tams." We believe the costs of litigation and any damages that may be awarded in the FKTC and Burn Pit matters described below are billable under the LogCAP III contract and that any such costs or damages awarded in the Sodium Dichromate matter are billable under the RIO contract and a related indemnity agreement with the U.S. government. All costs billed under LogCAP III or RIO are subject to audit by the DCAA for reasonableness. First Kuwaiti Trading Company arbitration. In April 2008, FKTC, one of our LogCAP III subcontractors providing housing containers, filed for arbitration with the American Arbitration Association of all its claims under various LogCAP III subcontracts. After complete hearings on all claims, the arbitration panel awarded FKTC $17 million plus interest for claims involving damages on lost or unreturned vehicles. In addition, we determined that we owe FKTC $32 million in connection with other subcontracts. We paid FKTC $19 million and will pay $4 million on pay-when-paid terms in the contract. We have accrued amounts we believe are payable to FKTC in "accounts payable" and "other current liabilities" on our condensed consolidated balance sheets. The remaining $26 million owed to FKTC under the contract has not been billed to the government and we will not do so until the related claims and disputes between KBR and the government over the FKTC living container contract are resolved (see DOJ False Claims Act complaint - FKTC Containers below). At this time, we believe the likelihood that we would incur a loss related to this matter in excess of the amounts we have accrued is remote. Burn Pit litigation. From November 2008 through current, KBR has been served with in excess of 60 lawsuits in various states alleging exposure to toxic materials resulting from the operation of burn pits in Iraq or Afghanistan in connection with services provided by KBR under the LogCAP III contract. These suits have been consolidated and are pending in U.S. Federal District Court in Baltimore, Maryland, where the jurisdictional issues are now under advisement. The plaintiffs are claiming unspecified damages. KBR will continue to pursue all available jurisdictional and other dismissal options. At this time, we believe the likelihood that we would incur a loss related to this matter is remote. As of March 31, 2017 , no amounts have been accrued. Sodium Dichromate litigation. From December 2008 through September 2009, five cases were filed in various Federal District Courts against KBR by national guardsmen and other military personnel alleging exposure to sodium dichromate at the Qarmat Ali Water Treatment Plant in Iraq in 2003, which were consolidated into the case pending in the U.S. District Court for the Southern District of Texas. The Texas case was then dismissed by the court on the merits on multiple grounds including the conclusion that no one was injured. In March 2017, the Fifth Circuit Court of Appeals upheld the trial court's dismissal of plaintiffs' claims on summary judgment. The plaintiffs may appeal this ruling. The plaintiffs are claiming unspecified damages. At this time, we believe the likelihood that we would incur a loss related to this matter is remote. As of March 31, 2017 , no amounts have been accrued. Qui tams. We have several qui tam cases pending, one of which has been joined by the U.S. government (see DOJ False Claims Act complaint - Iraq Subcontractor below). At this time, we believe the likelihood that we would incur a loss in the qui tams the U.S. government has not joined is remote and as of March 31, 2017 , no amounts have been accrued. Costs incurred in defending the qui tams cannot be billed to the U.S. government until those matters are successfully resolved in our favor. If successfully resolved, we can bill 80% of the costs to the U.S. government under the federal regulations. As of March 31, 2017 , we have incurred and expensed $10 million in legal costs to date in defending ourselves in qui tams. There are two active cases as discussed below. Barko qui tam. Relator Harry Barko, a KBR subcontracts administrator in Iraq for a year in 2004/2005, filed a qui tam lawsuit in June 2005 in the U.S. District Court for the District of Columbia, alleging violations of the FCA by KBR and its subcontractors Daoud & Partners and Eamar Combined for General Trading and Contracting. The DOJ investigated Barko's allegations and elected not to intervene. The claim was unsealed in March of 2009. On March 14, 2017 the Court granted KBR's motion for summary judgment and dismissed the case. The plaintiff has filed a notice of appeal. Howard qui tam. In March 2011, Geoffrey Howard filed a complaint in the U.S. District Court for the Central District of Illinois alleging that KBR mischarged the government $628 million for unnecessary materials and equipment. In October 2014 the DOJ declined to intervene and the case was partially unsealed. The case is starting discovery. DOJ False Claims Act complaint - FKTC Containers. In November 2012, the DOJ filed a complaint in the U.S. District Court for the Central District of Illinois against KBR, FKTC and others, related to our settlement of delay claims by our subcontractor, FKTC, in connection with FKTC's provision of living trailers for the bed down mission in Iraq in 2003-2004. The DOJ alleges that KBR submitted false claims to the U.S. government for reimbursement of costs for FKTC's services of, which the U.S. government alleges were inflated, unverified, not subject to an adequate price analysis and had been contractually assumed by FKTC. Our contractual dispute with the Army over this settlement has been ongoing since 2005. In March 2014, KBR's motion to dismiss was denied and in September 2014, the District Court granted FKTC's motion to dismiss for lack of personal jurisdiction. The case is currently in discovery which we expect to be substantially completed in the fourth quarter of 2017. At this time, we believe the likelihood that we would incur a loss related to this matter is remote. As of March 31, 2017 , no amounts have been accrued. KBR Contract Claim on FKTC containers. KBR previously filed a claim before the ASBCA to recover the costs paid to FKTC to settle its delay and disruption claims. The DCMA had disallowed the majority of those costs. Those contract claims were stayed in 2013 at the request of the DOJ so that they could pursue the FCA case referenced above. Those claims were reinstated in 2016. This matter is now set for trial in September 2017. DOJ False Claims Act complaint - Iraq Subcontractor. In January 2014, the DOJ filed a complaint in the U.S. District Court for the Central District of Illinois against KBR and two former KBR subcontractors, including FKTC, alleging that three former KBR employees were offered and accepted kickbacks from these subcontractors in exchange for favorable treatment in the award and performance of subcontracts to be awarded during the course of KBR's performance of the LogCAP III contract in Iraq. The complaint alleges that as a result of the kickbacks, KBR submitted invoices with inflated or unjustified subcontract prices, resulting in alleged violations of the FCA and the Anti-Kickback Act. The DOJ's investigation dates back to 2004. We self-reported most of the violations and tendered credits to the U.S. government as appropriate. On May 22, 2014, FKTC filed a motion to dismiss which the U.S. government opposed. Following the submission of our answer in April 2014, the U.S. government was granted a Motion to Strike certain affirmative defenses in March 2015. We do not believe this limits KBR's ability to fully defend all allegations in this matter. As of March 31, 2017

Commitments and Contingencies Disclosure [Text Block]	Other Commitments and Contingencies Litigation and regulatory matters related to the Company’s restatement of its 2013 annual financial statements In re KBR, Inc. Securities Litigation . Lead plaintiffs, Arkansas Public Employees Retirement System and IBEW Local 58/NECA Funds, sought class action status on behalf of our shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against the Company, our former chief executive officer, our previous two former chief financial officers, and our former chief accounting officer, arising out of the restatement of our 2013 annual financial statements, and seek undisclosed damages. We reached an agreement to settle this case as of January 11, 2017 and accrued the proposed settlement amount as of December 31, 2016 in "other current liabilities" on our consolidated balance sheets, net of insurance proceeds, which did not have a material impact to our financial statements. On April 6, 2017 we received preliminary Court approval for the settlement. Butorin v. Blount et al , is a May 2014 shareholder derivative complaint pending in the U.S. District Court of Delaware and filed on behalf of the Company naming certain current and former members of the Company's board of directors as defendants and the Company as a nominal defendant. The complaint alleges that the named directors breached their fiduciary duties by permitting the Company's internal controls to be inadequate. KBR has filed a Motion to Dismiss, to which the derivative plaintiff has responded. At this time, we are not yet able to determine the likelihood of loss, if any, arising from this matter. We have also received requests for information and a subpoena for documents from the SEC regarding the restatement of our 2013 annual financial statements. We have been and intend to continue cooperating with the SEC. We have accrued our estimate of a potential settlement in "other current liabilities" on our consolidated balance sheets which did not have a material impact to our financial statements. PEMEX and PEP Arbitration In 2004, we filed for arbitration with the ICC claiming recovery of damages against PEP, a subsidiary of PEMEX, the Mexican national oil company, related to a 1997 contract between PEP and our subsidiary, Commissa, and PEP subsequently counterclaimed. The project, known as EPC 1, required Commissa to build offshore platforms and treatment and reinjection facilities in Mexico and encountered significant schedule delays and increased costs due to problems with design work, late delivery and defects in equipment, increases in scope and other changes. In 2009, the ICC arbitration panel awarded us a total of approximately $351 million including legal and administrative recovery fees as well as interest and PEP was awarded approximately $6 million on counterclaims, plus interest on a portion of that sum. In August 2016, the U.S. Court of Appeal for the Second Circuit affirmed a 2013 District Court ruling confirming the ICC award and PEP filed a Motion for Rehearing in September 2016. PEP posted $465 million as security for the judgment, pending exhaustion of all appeals. On April 6, 2017, we entered into a settlement agreement with PEMEX and PEP resolving this dispute. The settlement will be recognized in the second quarter of 2017 and provides for a cash payment to Commissa of $435 million , payment by PEP of all VAT related to the settlement amount and mutual dismissals and releases of all claims related to the EPC 1 project. This matter is now resolved and all amounts were paid by PEP in April 2017. Other Matters The DOJ, SEC, and the SFO are conducting investigations of Unaoil, a Monaco based company, in relation to international projects involving several global companies, including KBR, whose interactions with Unaoil are a subject of those investigations. KBR is cooperating with the DOJ, SEC, and the SFO in their investigations, which includes the voluntary submission of information and compliance with formal document requests, including a subpoena from the SEC and a Section 2 notice from the SFO.

Share Repurchases	Share Repurchases Authorized Share Repurchase Program On February 25, 2014, our Board of Directors authorized a plan to repurchase up to $350 million of our outstanding common shares, which replaced and terminated the August 26, 2011 share repurchase program. The authorization does not obligate the Company to acquire any particular number of common shares and may be commenced, suspended or discontinued without prior notice. The share repurchases are intended to be funded through the Company’s current and future cash and the authorization does not have an expiration date. Withheld to Cover Program In addition to the plans above, we also have in place a "withheld to cover" program, which allows us to withhold ordinary shares from employees in connection with the settlement of income tax and related benefit withholding obligations arising from the issuance of share based equity awards under the KBR, Inc. 2006 Stock and Incentive Plan.

Fair Value Disclosures [Abstract]
Fair Value, Concentration of Risk	Financial Instruments and Risk Management Foreign currency risk. We conduct business globally in numerous currencies and are therefore exposed to foreign currency fluctuations. We may use derivative instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. We do not use derivative instruments for speculative trading purposes. We generally utilize foreign exchange forwards and currency option contracts to hedge exposures associated with forecasted future cash flows and to hedge exposures present on our balance sheet. As of March 31, 2017 , the gross notional value of our foreign currency exchange forwards and option contracts used to hedge balance sheet exposures was $87 million , all of which had durations of 10 days or less. We also had approximately $15 million (gross notional value) of cash flow hedges which had durations of approximately 28 months or less. The fair value of our balance sheet and cash flow hedges included in "other current assets" and "other current liabilities" on our condensed consolidated balance sheets was immaterial at March 31, 2017 and December 31, 2016 , respectively. The fair values of these derivatives are considered Level 2 under ASC 820, Fair Value Measurement, as they are based on quoted prices directly observable in active markets. The following table summarizes the recognized changes in fair value of our balance sheet hedges offset by remeasurement of balance sheet positions. These amounts are recognized in our condensed consolidated statements of operations for the periods presented. The net of our changes in fair value of hedges and the remeasurement of our assets and liabilities is included in "other non-operating expense" on our condensed consolidated statements of operations.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. This ASU is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demands, uncertainties and events in our business. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted, for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demands, uncertainties and events in our business. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. This ASU addresses eight specific cash flow topics with the objective of reducing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted, including adoption in an interim period. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demands, uncertainties and events in our business. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. This ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable supportable forecast and is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted for annual periods after December 15, 2018, including interim periods within those annual periods. We are currently in the process of assessing the impact of this ASU on our financial statements. We have not yet determined the effect of the standard on our ongoing financial reporting or the future impact of adoption on known trends, demands, uncertainties and events in our business. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms longer than 12 months. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. This ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. We are currently in the process of assessing the impact of this ASU on our financial statements. We have not yet determined the effect of the standard on our ongoing financial reporting or the future impact of adoption on known trends, demands, uncertainties and events in our business. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, as amended (Topic 606), which will change the way we recognize revenue and significantly expand the disclosure requirements for revenue arrangements. In July 2015, the FASB approved a one-year deferral of the effective date of the standard to 2018 for public companies, with an option that would permit companies to adopt the standard in 2017. Further amendments and technical corrections were made to the standard during 2016. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application.

Accounting Policies [Abstract]
Principles of consolidation	Principles of Consolidation Our condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR and our wholly owned and majority-owned subsidiaries and VIEs of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 9 to our condensed consolidated financial statements for further discussion on our equity investments and VIEs. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation on the condensed consolidated statements of operations, condensed consolidated balance sheets and the condensed consolidated statements of cash flows. We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures.
Use of estimates	Use of Estimates The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Areas requiring significant estimates and assumptions by our management include the following: • project revenues, costs and profits on engineering and construction contracts, including recognition of estimated losses on uncompleted contracts • project revenues, award fees, costs and profits on government services contracts • provisions for uncollectible receivables and client claims and recoveries of costs from subcontractors, vendors and others • provisions for income taxes and related valuation allowances and tax uncertainties • recoverability of goodwill • recoverability of other intangibles and long-lived assets and related estimated lives • recoverability of equity method and cost method investments • valuation of pension obligations and pension assets • accruals for estimated liabilities, including litigation accruals • consolidation of VIEs • valuation of share-based compensation • valuation of assets and liabilities acquired in business combinations
