Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation Our accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the instructions to SEC Form 10-Q and Article 10 of SEC Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017 . For further information refer to the consolidated financial statements and footnotes thereto included in our 2016 Form 10-K. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the financial statements include accruals for contract disallowance reserves, recoverability of goodwill and intangible assets, and earn-out obligations. Recently Adopted Accounting Pronouncements Effective January 1, 2017, we adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which is intended to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. We have elected to account for forfeitures as they occur. The adoption of ASU 2016-09 did not have a significant impact on our consolidated financial position, results of operations or cash flows. Effective January 1, 2017, we adopted ASU No. 2015-11, Simplifying the Measurement of Inventory , which clarifies that, for inventories measured at the lower of cost and net realizable value, net realizable value should be determined based on the estimated selling prices in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The adoption of ASU 2015-11 did not have a significant impact on our consolidated financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment , which eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in ASU 2017-04, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new standard is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis with early adoption permitted. We elected to early adopt ASU 2017-04 effective April 1, 2017 and will apply the new standard to our 2017 annual goodwill impairment test, as well as any interim tests. The adoption is not expected to have a significant impact on our consolidated financial position, results of operations or cash flows. Stock Split Effected in Form of Stock Dividend In May 2016, our Board of Directors approved a two -for-one stock split effected in the form of a stock dividend ("Stock Split"). The Stock Split had a record date of July 20, 2016 and the stock distribution occurred on August 3, 2016. All references made to share or per share amounts in the accompanying unaudited consolidated financial statements and disclosures have been retroactively adjusted to reflect the Stock Split.

Debt Disclosure [Abstract]
Debt	Debt We have a loan agreement with a group of banks that was amended in January 2015 to fund our Aviation Acquisition and provide working capital for our continuing operations. The loan agreement, which expires in January 2020 , is comprised of a term loan facility and a revolving loan facility. The revolving loan facility provides for revolving loans and letters of credit. Our required term loan payments after September 30, 2017 are approximately $5.6 million in 2017, $28.1 million in 2018, $30.0 million in 2019, and $36.3 million in 2020. The amount of term loan borrowings outstanding as of September 30, 2017 was $100.0 million . The maximum amount of credit available to us under the loan agreement for revolving loans and letters of credit as of September 30, 2017 was $150 million . We may borrow and repay the revolving loan borrowings as our cash flows require or permit. We pay an unused commitment fee and fees on letters of credit that are issued. We had approximately $82.1 million in revolving loan amounts outstanding and no letters of credit outstanding as of September 30, 2017 . We had approximately $100.4 million in revolving loan amounts outstanding and no letters of credit outstanding as of December 31, 2016 . Under the loan agreement we may elect to increase the maximum availability of the term loan facility, the revolving loan facility, or both facilities up to an aggregate additional amount of $75 million . Total bank loan borrowed funds outstanding, including term loan borrowings and revolving loan borrowings, were approximately $182.1 million and $216.3 million , as of September 30, 2017 and December 31, 2016 , respectively. These amounts exclude unamortized deferred financing costs of approximately $1.3 million and $1.7 million as of September 30, 2017 and December 31, 2016 , respectively, which are being amortized over a five -year period through July 2020. The fair value of outstanding debt as of September 30, 2017 under our bank loan facilities approximates its carrying value using Level 2 inputs based on market data on companies with a corporate rating similar to ours that have recently priced credit facilities. We pay interest on the term loan borrowings and revolving loan borrowings at LIBOR plus a base margin or at a base rate (typically the prime rate) plus a base margin. As of September 30, 2017 , the LIBOR base margin was 2.00% and the base rate base margin was 0.75% . The base margins increase or decrease in increments as our Total Funded Debt/EBITDA Ratio increases or decreases. The loan agreement requires us to have interest rate hedges on a portion of the outstanding term loan for the first three years after the January 2015 amendment date of the agreement. We executed interest rate swap agreements in February 2015 that complied with the loan agreement. The notional amount of the interest rate swap agreements as of September 30, 2017 was $85 million . After taking into account the impact of interest rate swap agreements, as of September 30, 2017 , interest rates on portions of our outstanding debt ranged from 3.24% to 5.00% , and the effective interest rate on our aggregate outstanding debt was 3.36% . Interest expense incurred on bank loan borrowings and interest rate hedges was approximately $1.8 million and $2.0 million for the quarters ended September 30, 2017 and 2016 , respectively. Interest expense incurred on bank loan borrowings and interest rate hedges was approximately $5.6 million and $5.8 million for the nine months ended September 30, 2017 and 2016, respectively. The loan agreement contains collateral requirements to secure our borrowings and other loan agreement obligations, restrictive covenants, a limit on annual dividends, and other affirmative and negative covenants, conditions, and limitations. Restrictive covenants include a maximum Total Funded Debt/EBITDA Ratio, which decreases over time, and a minimum Fixed Charge Coverage Ratio. We were in compliance with required ratios and other terms and conditions at September 30, 2017 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies Hawaii Litigation In 2012, the estates of five deceased individuals and their relatives filed complaints in a state court in Hawaii against VSE and other entities and individuals for unspecified damages, alleging that the explosion of fireworks and diesel fuel that killed the five individuals in April 2011 was caused by negligence of VSE and the other defendants. The five deceased plaintiffs were employees of a vendor retained by VSE to dispose of fireworks and other explosives seized by the federal government. In September 2017, VSE together with its insurance carriers, agreed in principle with all of the plaintiffs to settle this litigation. The settlement documents are being finalized and the settlement will be fully funded by VSE’s insurers, resulting in no material adverse effect on our results of operations, financial condition, or cash flows. We have recorded as of September 30, 2017 a liability for our estimated amount of the settlement and a related receivable from our insurers for our estimated recovery, which we believe is probable of recovery based on our evaluation of insurance coverage and the insurers’ agreement and ability to fully fund the settlement. Aviation Litigation In November 2016, a lawsuit, Arrieta et al vs. Prime Turbines LLC et al, was filed in the District Court of Texas in Dallas County, by Edgar Arrieta, and four other plaintiffs against VSE subsidiaries, Kansas Aviation of Independence, L.L.C. and Prime Turbines LLC, and three other unrelated defendants. The other named defendants are Pratt & Whitney of Canada Corporation, Cessna Aircraft Company and Woodward Inc. The plaintiffs allege that on April 1, 2016, a plane crashed resulting in the death of three plaintiffs and serious injuries to six other plaintiffs and that VSE's subsidiaries were negligent in providing maintenance, service and inspection of the airplane engine prior to the crash. Plaintiffs are seeking monetary relief over $1.0 million from the defendants. Trial is scheduled for May 2018. VSE together with its insurance carrier, will aggressively defend the proceedings. While the results of legal proceedings cannot be predicted with certainty and the amount of loss, if any, cannot be reasonably estimated, we do not anticipate that this lawsuit will have a material adverse effect on our results of operation, financial condition, or cash flows. Other Matters In addition to the above-referenced legal proceedings, we may have certain claims in the normal course of business, including legal proceedings, against us and against other parties. In our opinion, the resolution of these other claims will not have a material adverse effect on our results of operations, financial position, or cash flows. However, because the results of any legal proceedings cannot be predicted with certainty, the amount of loss, if any, cannot be reasonably estimated. Further, from time-to-time, government agencies investigate whether our operations are being conducted in accordance with applicable contractual and regulatory requirements. Government investigations of us, whether relating to government contracts or conducted for other reasons, could result in administrative, civil or criminal liabilities, including repayments, fines or penalties being imposed upon us, or could lead to suspension or debarment from future government contracting. Government investigations often take years to complete and many result in no adverse action against us. We believe, based upon current information, that the outcome of any such government disputes and investigations will not have a material adverse effect on

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]
Business Segments and Customer Information	Business Segments and Customer Information Business Segments Beginning in 2017, we changed our structure and as a result our former IT, Energy and Management Consulting Group is now combined with our Federal Services Group. Consequently, our segment financial information for 2016 has been restated to reflect such change. Management of our business operations is conducted under three reportable operating segments: Supply Chain Management Group – Our Supply Chain Management Group supplies vehicle parts primarily through a Managed Inventory Program ("MIP") and direct sales to the United States Postal Service ("USPS") and to other customers. Aviation Group – Our Aviation Group provides maintenance, repair and overhaul ("MRO") services, parts supply and distribution, and supply chain solutions for general aviation jet aircraft engines and engine accessories. Federal Services Group – Our Federal Services Group provides engineering, industrial, logistics, foreign military sales, legacy equipment sustainment services, IT and technical and consulting services primarily to the United States Department of Defense ("DoD") and other government agencies. The operating segments reported below are the segments of the Company for which separate financial information is available and for which segment results are evaluated regularly by our Chief Executive Officer in deciding how to allocate resources and in assessing performance. We evaluate segment performance based on consolidated revenues and operating income. Net sales of our business segments exclude intersegment sales as these activities are eliminated in consolidation.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The accounting standard for fair value measurements defines fair value, and establishes a market-based framework or hierarchy for measuring fair value. The standard is applicable whenever assets and liabilities are measured at fair value. The fair value hierarchy established in the standard prioritizes the inputs used in valuation techniques into three levels as follows: Level 1–Observable inputs–quoted prices in active markets for identical assets and liabilities; Level 2–Observable inputs-other than the quoted prices in active markets for identical assets and liabilities–includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets and amounts derived from valuation models where all significant inputs are observable in active markets; and Level 3–Unobservable inputs–includes amounts derived from valuation models where one or more significant inputs are unobservable and require us to develop relevant assumptions. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016 and the level they fall within the fair value hierarchy (in thousands): Amounts Recorded at Fair Value Financial Statement Classification Fair Value Hierarchy Fair Value September 30, 2017 Fair Value December 31, 2016 Non-COLI assets held in Deferred Supplemental Compensation Plan Other assets Level 1 $ 367 $ 299 Interest rate swaps Other current assets Level 2 $ 218 $ 73 Non-COLI assets held in the deferred supplemental compensation plan consist of equity funds with fair value based on observable inputs such as quoted prices for identical assets in active markets and changes in fair value are recorded as selling, general and administrative expenses. We account for our interest rate swap agreements under the provisions of ASC 815, Derivatives and Hedging , and have determined that our swap agreements qualify as highly effective cash flow hedges. The fair value of the swap agreements was approximately $218 thousand and $73 thousand at September 30, 2017 and December 31, 2016 , respectively. The offset, net of an income tax effect of approximately $84 thousand and $28 thousand , was included in accumulated other comprehensive income in the accompanying balance sheets as of September 30, 2017 and December 31, 2016 , respectively. The amounts paid and received on the swap agreements are recorded in interest expense in the period during which the related floating-rate interest is incurred. We determine the fair value of the swap agreements based on a valuation model using primarily observable market data inputs.

Income Taxes	Income Taxes Our effective tax rate was 36.6% and 36.4% for the nine months ended September 30, 2017 and 2016 , respectively. Income tax expense during interim periods is based on our estimated annual effective income tax rate plus any discrete items that are recorded in the period in which they occur. Our tax rate is affected by discrete items that may occur in any given year, but may not be consistent from year to year.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The new standard is effective for reporting periods beginning after December 15, 2019 with early adoption permitted for reporting periods beginning after December 15, 2018. We currently are assessing the impact that this standard will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new standard is effective for reporting periods beginning after December 15, 2018 with early adoption permitted. We currently are assessing the impact that this standard will have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the goods or services. The standard is required to be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. We are in the process of comparing our current revenue recognition policies to the requirements of the new standard for each of our revenue categories and evaluating the effect of adoption on our consolidated financial statements by assessing a selection of contracts. Based on the assessment we have completed thus far, we believe the primary impacts of adopting the new standard will be on (1) the timing of when we recognize revenue on our contracts with award fees, which is currently based on when we receive customer authorization will change to recognition of the award fees as the performance obligation is satisfied resulting in revenue being recognized earlier in the contract period , (2) the timing of when we recognize revenues and costs on MRO services for aviation clients and certain fixed price delivery contracts will change from the date of delivery to recognition over time as progress is made to satisfy the performance obligation, and (3) the pattern in which we recognize revenue on certain fixed price services contracts may change from a straight-line basis over the contract period to measuring progress using input measures, such as costs incurred. While we have identified these areas of change under the new standard, we are also identifying and implementing changes to our business processes, systems and controls to support adoption of the new standard in 2018. The new standard requires additional detailed disclosures regarding the company’s contracts with customers, including disclosure of remaining unsatisfied performance obligations, in the first quarter 2018 which we are continuing to assess. The new standard will be effective beginning January 1, 2018 and we intend to implement the standard with the modified retrospective approach, which recognizes the cumulative effect of application recognized on that date. The cumulative catch-up adjustment that will be recorded through shareholders’ equity on January 1, 2018 is still being quantified. We will continue evaluating the impact of the standard on our contract portfolio through the date of adoption.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	Our accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the instructions to SEC Form 10-Q and Article 10 of SEC Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017 . For further information refer to the consolidated financial statements and footnotes thereto included in our 2016 Form 10-K.
Use of Estimates	The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the financial statements include accruals for contract disallowance reserves, recoverability of goodwill and intangible assets, and earn-out obligations.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Effective January 1, 2017, we adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2016-09, Improvements to Employee Share-Based Payment Accounting , which is intended to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. We have elected to account for forfeitures as they occur. The adoption of ASU 2016-09 did not have a significant impact on our consolidated financial position, results of operations or cash flows. Effective January 1, 2017, we adopted ASU No. 2015-11, Simplifying the Measurement of Inventory , which clarifies that, for inventories measured at the lower of cost and net realizable value, net realizable value should be determined based on the estimated selling prices in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The adoption of ASU 2015-11 did not have a significant impact on our consolidated financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment , which eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in ASU 2017-04, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new standard is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis with early adoption permitted. We elected to early adopt ASU 2017-04 effective April 1, 2017 and will apply the new standard to our 2017 annual goodwill impairment test, as well as any interim tests. The adoption is not expected to have a significant impact on our consolidated financial position, results of operations or cash flows. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded.

Stock Split Effected In Form of Stock Dividend	Stock Split Effected in Form of Stock Dividend In May 2016, our Board of Directors approved a two -for-one stock split effected in the form of a stock dividend ("Stock Split"). The Stock Split had a record date of July 20, 2016 and the stock distribution occurred on August 3, 2016. All references made to share or per share amounts in the accompanying unaudited consolidated financial statements and disclosures have been retroactively adjusted to reflect the Stock Split.
Earnings Per Share	Basic earnings per share ("EPS") has been computed by dividing net income by the weighted average number of shares of common stock outstanding during each period. Shares issued during the period are weighted for the portion of the period that they were outstanding. Our calculation of diluted earnings per common share includes the dilutive effects for an assumed vesting of restricted stock awards.
Business Segments	Business Segments Beginning in 2017, we changed our structure and as a result our former IT, Energy and Management Consulting Group is now combined with our Federal Services Group. Consequently, our segment financial information for 2016 has been restated to reflect such change. Management of our business operations is conducted under three reportable operating segments: Supply Chain Management Group – Our Supply Chain Management Group supplies vehicle parts primarily through a Managed Inventory Program ("MIP") and direct sales to the United States Postal Service ("USPS") and to other customers. Aviation Group – Our Aviation Group provides maintenance, repair and overhaul ("MRO") services, parts supply and distribution, and supply chain solutions for general aviation jet aircraft engines and engine accessories. Federal Services Group – Our Federal Services Group provides engineering, industrial, logistics, foreign military sales, legacy equipment sustainment services, IT and technical and consulting services primarily to the United States Department of Defense ("DoD") and other government agencies. The operating segments reported below are the segments of the Company for which separate financial information is available and for which segment results are evaluated regularly by our Chief Executive Officer in deciding how to allocate resources and in assessing performance. We evaluate segment performance based on consolidated revenues and operating income. Net sales of our business segments exclude intersegment sales as these activities are eliminated in consolidation.
Fair Value Measurements	The accounting standard for fair value measurements defines fair value, and establishes a market-based framework or hierarchy for measuring fair value. The standard is applicable whenever assets and liabilities are measured at fair value. The fair value hierarchy established in the standard prioritizes the inputs used in valuation techniques into three levels as follows: Level 1–Observable inputs–quoted prices in active markets for identical assets and liabilities; Level 2–Observable inputs-other than the quoted prices in active markets for identical assets and liabilities–includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets and amounts derived from valuation models where all significant inputs are observable in active markets; and Level 3–Unobservable inputs–includes amounts derived from valuation models where one or more significant inputs are unobservable and require us to develop relevant assumptions.
