Accounting Policies [Abstract]
Nature of Business and Significant Accounting Policies	Nature of Business and Summary of Significant Accounting Policies Nature of Business The term "VSE," the "Company," "us," "we," or "our" means VSE and its subsidiaries and divisions unless the context indicates operations of only VSE as the parent company. Our operations include aftermarket supply chain management solutions and parts supply for vehicle fleets; maintenance, repair, and overhaul ("MRO") services and parts supply for aviation clients; vehicle and equipment maintenance and refurbishment; logistics; engineering; energy services; IT and health care IT solutions; and consulting services. We serve the United States Government (the "government"), including the United States Department of Defense ("DoD"), federal civilian agencies, and other commercial customers. Principles of Consolidation and Basis of Presentation The consolidated financial statements consist of the operations of our parent company and our wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States ("U.S. GAAP") requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies 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 may include, but are not limited to, fair value measurements, inventory provisions, collectability of receivables, estimated profitability of long-term contracts, valuation allowances on deferred tax assets, fair value of goodwill and other intangible assets and contingencies. Stock-Based Compensation We issue stock-based awards as compensation to employees and directors. Stock-based awards include stock-settled bonus awards, vesting stock awards and performance share awards. We recognize stock-based compensation expense over the underlying award’s requisite service period, as measured using the award’s grant date fair value. Our policy is to recognize forfeitures as they occur. For performance share awards, we assess the probability of achieving the performance conditions at each reporting period end and adjust compensation expense based on the number of shares we expect to ultimately issue. Earnings Per Share Basic earnings per share ("EPS") is 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 the assumed vesting of outstanding stock-based awards. As a result of incurring a net loss for the year ended December 31, 2020, potential dilutive shares were excluded from diluted loss per share as the effect would have been anti-dilutive. The antidilutive common stock equivalents excluded from the diluted per share calculation were not material. Years Ended December 31, 2022 2021 2020 Basic weighted average common shares outstanding 12,780,117 12,551,459 11,034,256 Effect of dilutive shares 47,777 81,415 — Diluted weighted average common shares outstanding 12,827,894 12,632,874 11,034,256 Cash and Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Due to the short maturity of these instruments, the carrying values on our consolidated balance sheets approximate fair value. Property and Equipment Property and equipment is recorded at cost, net of accumulated depreciation and amortization. Depreciation and amortization is generally provided on the straight-line method over the estimated useful lives of the various assets. Property and equipment is generally depreciated over the following estimated useful lives: computer equipment, furniture, other equipment from three Leases We determine at inception whether an arrangement that provides us control over the use of an asset is a lease. Substantially all of our leases are long-term operating leases for facilities with fixed payment terms. We recognize a right-of-use ("ROU") asset and a lease liability upon commencement of our operating leases. The initial lease liability is equal to the future fixed minimum lease payments discounted using our incremental borrowing rate, on a secured basis. The lease term includes option renewal periods and early termination payments when it is reasonably certain that we will exercise those rights. The initial measurement of the ROU asset is equal to the initial lease liability plus any initial indirect costs and prepayments, less any lease incentives. We recognize lease costs on a straight-line basis over the remaining lease term, except for variable lease payments that are expensed in the period in which the obligation for those payments is incurred. Leases with an initial term of 12 months or less with purchase options or extension options that are not reasonably certain to be exercised are not recorded on the balance sheet. Operating lease cost is included in costs and operating expenses on our consolidated statement of income. Concentration of Credit Risk Financial instruments that potentially subject us to concentration of credit risk consist primarily of our trade receivables. Our trade receivables consist of amounts due from various commercial entities and government clients. We believe that concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the customer base and their dispersion across many different geographic regions. Contracts with the government, either as a prime or subcontractor, accounted for approximately 47%, 57%, and 69% of revenues for the years ended December 31, 2022, 2021 and 2020, respectively. The credit risk, with respect to contracts with the government, is limited due to the creditworthiness of the respective governmental entity. We perform ongoing credit evaluations and monitoring of the financial condition of all our customers. We maintain an allowance for credit losses based upon several factors, including historical collection experience, current aging status of the customer accounts and financial condition of our customers. Revenue Recognition We account for revenue in accordance with ASC 606. The unit of account in ASC 606 is a performance obligation. At the inception of each contract with a customer, we determine our performance obligations under the contract and the contract's transaction price. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the respective goods or services is not separately identifiable from other promises in the contracts and is, therefore, not distinct. For product sales, each product sold to a customer typically represents a distinct performance obligation. Our performance obligations are satisfied over time as work progresses or at a point in time based on transfer of control of products and services to our customers. Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for goods or services that are not distinct, and therefore are accounted for as part of the existing contract. Substantially all our Fleet segment revenues from the sale of vehicle parts to customers are recognized at the point in time of the transfer of control to the customer. Sales returns and allowances for vehicle parts are not significant. Our Aviation segment revenues result from the sale of aircraft parts and performance of MRO services for private and commercial aircraft owners, other aviation MRO providers, and aviation original equipment manufacturers. Our Aviation segment recognizes revenues for the sale of aircraft parts at a point in time when control is transferred to the customer, which usually occurs when the parts are shipped. Our Aviation segment recognizes revenues for MRO services over time as the services are transferred to the customer. MRO services revenue recognized is measured based on the cost-to-cost input method, as costs incurred reflect the work completed, and therefore the services transferred to date. Sales returns and allowances are not significant. Our Federal and Defense segment revenues result from professional and technical services, which we perform for customers on a contract basis. Revenue is recognized for performance obligations over time as we transfer the services to the customer. The three primary types of contracts used are cost-type, fixed-price and time-and-materials. Revenues result from work performed on these contracts by our employees and our subcontractors and from costs for materials and other work-related costs allowed under our contracts. Revenues on cost-plus contracts are recorded as contract allowable costs are incurred and fees are earned. Variable consideration is included in the estimated transaction price, to the extent that it is probable that a significant reversal will not occur, when there is a basis to reasonably estimate the amount of the fee. These estimates are based on historical award experience, anticipated performance and our best judgment based on current facts and circumstances. Revenues on fixed-price contracts are recorded as work is performed over the period. We generally recognize revenue using the time-elapsed output method for our fixed-price service offering performance obligations. For certain deliverable-based fixed-price performance obligations, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion. For such contracts, we estimate total costs at the inception of the contract based on our assumptions of the cost elements required to complete the associated tasks of the contract and assess the impact of the risks on our estimates of total costs to complete the contract. Our cost estimates are based on assumptions that include the complexity of the work, our employee labor costs, the cost of materials and the performance of our subcontractors. These cost estimates are subject to change as we perform under the contract and as a result, the timing of revenues and amount of profit on a contract may change as there are changes in estimated costs to complete the contract. Such adjustments are recognized on a cumulative catch-up basis in the period we identify the changes. Revenues for time and materials ("T&M") contracts are recorded based on the amount for which we have the right to invoice our customers, because the amount directly reflects the value of our work performed for the customer. Revenues are recorded on the basis of contract allowable labor hours worked multiplied by the contract defined billing rates, plus the direct costs and indirect cost burdens associated with materials and subcontract work used in performance on the contract. Generally, profits on time and materials contracts result from the difference between the cost of services performed and the contract defined billing rates for these services. Revenues related to work performed on government contracts at risk, which is work performed at the customer's request prior to the government formalizing funding, is not recognized until it can be reliably estimated, and its realization is probable. A substantial portion of contract and administrative costs are subject to audit by the Defense Contract Audit Agency. Our indirect cost rates have been audited and approved for 2021 and prior years with no material adjustments to our results of operations or financial position. While we maintain reserves to cover the risk of potential future audit adjustments based primarily on the results of prior audits, we do not believe any future audits will have a material adverse effect on our results of operations, financial position, or cash flows. Receivables and Unbilled Receivables Receivables are recorded at amounts earned less an allowance. We review our receivables regularly to determine if there are any potentially uncollectible accounts. The majority of our receivables are from government agencies, where there is minimal credit risk. Unbilled receivables include amounts typically resulting from sales under contracts when the cost-to-cost method of revenue recognition is utilized, and revenue recognized exceeds the amount billed to the customer. The amounts may not exceed their estimated net realizable value. Unbilled receivables are classified as current based on our contract operating cycle. Allowance for Credit Losses We establish allowances for credit losses on our accounts receivable and unbilled receivables. To measure expected credit losses, we have disaggregated pools of receivable balances by segment. Within each segment, receivables exhibit similar risk characteristics. In determining the amount of the allowance for credit losses, we consider historical collectability based on past due status. We also consider current market conditions and forecasts of future economic conditions to inform potential adjustments to historical loss data. In addition, we also record allowance for credit losses for specific receivables that are deemed to have a higher risk profile than the rest of the respective pool of receivables, such as concerns about a specific customer's inability to meet its financial obligation to us. The adequacy of these allowances is assessed quarterly through consideration of factors on a collective basis where similar characteristics exist and on an individual basis. Inventories Inventories are stated at the lower of cost or net realizable value using the first-in, first-out ("FIFO") method. Inventories consist primarily of finished goods replacement parts for our Fleet and Aviation segments, and also include related purchasing, storage and handling costs. Inventories for our Aviation segment consist primarily of aftermarket parts for distribution, and general aviation engine accessories and parts, and also include related purchasing, overhaul labor, storage and handling costs. We periodically evaluate the carrying value of inventory, giving consideration to factors such as its physical condition, sales patterns and expected future demand in order to estimate the amount necessary to write down any slow moving, obsolete or damaged inventory. These estimates could vary significantly from actual amounts based upon future economic conditions, customer inventory levels or competitive factors that were not foreseen or did not exist when the estimated write-downs were made. During 2021, we recorded a $24.4 million provision for inventory within cost and operating expenses primarily related to slow moving and excess quantities of Aviation segment inventory supporting certain international region distribution programs entered into prior to 2019. Deferred Compensation Plans We established the VSE Corporation Deferred Supplemental Compensation Plan ("DSC Plan") for the benefit of certain key management employees to be incentivized and rewarded based on overall company performance. We recognized DSC Plan expenses of $0.3 million, $0.4 million and $1.0 million for the years ended December 31, 2022, 2021 and 2020, respectively. We invest in corporate owned life insurance ("COLI") products and in mutual funds that are held in a Rabbi Trust to fund the DSC Plan obligations. The COLI investments are recorded at cash surrender value and the mutual fund investments are recorded at fair value. The DSC Plan assets are included in other assets on the accompanying consolidated balance sheets. Gains and losses recognized on the changes in fair value of the investments are recorded as selling, general and administrative expenses on the accompanying consolidated statements of income. We recorded a net gain of $22 thousand and net losses of $0.6 million and $0.9 million for the years ended December 31, 2022, 2021 and 2020, respectively. Derivative Instruments Derivative instruments are recorded on the consolidated balance sheets at fair value. Unrealized gains and losses on derivatives designated as cash flow hedges are report in other comprehensive income (loss) and reclassified into earnings in a manner that matches the timing of the earnings impact of the hedged transactions. Income Taxes Income taxes are accounted for under the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. This method also requires the recognition of future tax benefits, such as net operating loss carryforwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The carrying value of net deferred tax assets is based on assumptions regarding our ability to generate sufficient future taxable income to utilize these deferred tax assets. Business Combinations We allocate the purchase price of acquired entities to the underlying tangible and identifiable intangible assets acquired and liabilities assumed based on their respective estimated fair values, with any excess recorded as goodwill. The operating results of acquired businesses are included in our results of operations beginning as of their effective acquisition dates. For contingent consideration arrangements, a liability is recognized at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. Goodwill and Other Intangible Assets Goodwill represents the purchase price paid in excess of the fair value of net tangible and intangible assets acquired in a business combination. Goodwill is tested for potential impairment at the reporting unit level annually at the beginning of the fourth quarter, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. We estimate and compare the fair value of each reporting unit to its respective carrying value including goodwill. The fair value of our reporting units is determined using a combination of the income approach and the market approach, which involves the use of estimates and assumptions, including projected future operating results and cash flows, the cost of capital, and financial measures derived from observable market data of comparable public companies. If the fair value is less than the carrying value, the amount of impairment expense is equal to the difference between the reporting unit’s fair value and the reporting unit’s carrying value. Intangible assets with finite lives are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives. Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment of Long-Lived Assets (Excluding Goodwill) We review our long-lived assets, including amortizable intangible assets and property and equipment, for impairment whenever events or changes in facts and circumstances indicate that their carrying values may not be fully recoverable. We assess impairment by comparing the estimated undiscounted future cash flows of the related asset to its carrying value. If an asset is determined to be impaired, we recognize an impairment charge in the current period for the difference between the fair value of the asset and its carrying value. Recent Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, "Revenue from Contracts with Customers," as if the acquirer had originated the contracts. The new standard is effective on a prospective basis for fiscal years and interim reporting periods within those fiscal years beginning after December 15, 2022, with early adoption permitted. We elected to early adopt this standard during the first quarter 2022 and will apply the guidance prospectively to business combinations entered into subsequent to adoption.

Business Combination and Asset Acquisition [Abstract]
Acquisition and Divestitures	Acquisitions and Divestitures Acquisitions Global Parts Group, Inc On July 26, 2021, our Aviation segment acquired Global Parts Group, Inc. ("Global Parts"), a privately owned company with operations in Augusta, Kansas. Global Parts provides distribution and MRO services for business and general aviation ("B&GA") aircraft families. The acquisition expands our existing B&GA focus and further diversifies our existing product and platform offerings to include additional airframe components, while expanding our customer base of regional and global B&GA customers. The cash purchase price for Global Parts was approximately $40 million, net of cash acquired, which was funded using our existing bank revolving loan. The purchase price included $2 million of contingent consideration. Refer to Note (17) "Fair Value Measurements," for additional information regarding the earn-out obligation. We completed the purchase accounting valuation for this transaction in 2021 and recorded the final purchase price allocation as follows (in thousands): Description Fair Value Accounts receivable $ 6,410 Inventories 13,240 Prepaid expenses and other current assets 620 Property and equipment 368 Intangibles - customer related 16,000 Goodwill 10,019 Operating lease right-of-use-assets 3,043 Long-term deferred tax assets 1,775 Accounts payable (6,112) Accrued expenses and other current liabilities (1,936) Long-term operating lease liabilities (2,874) Net assets acquired, excluding cash $ 40,553 Cash consideration, net of cash acquired $ 38,553 Acquisition date estimated fair value of earn-out obligation 2,000 Total consideration $ 40,553 The value attributed to the customer relationship intangible asset is being amortized on a straight-line basis using a useful life of 15 years. None of the value attributed to goodwill and customer relationships was deductible for income tax purposes. Goodwill resulting from the acquisition reflects the strategic advantage of expanding our supply chain management capabilities through the diversification of our existing product and platform offerings to new customers. We incurred approximately $0.5 million of acquisition-related expenses associated with our Global Parts acquisition for the year ended December 31, 2021, which are included in selling, general and administrative expenses. Global Parts' results of operations are included in our Aviation segment in the accompanying consolidated financial statements beginning on the acquisition date of July 26, 2021. Had the acquisition occurred as of January 1, 2020, revenue and net income (loss) from consolidated operations, and basic and diluted earnings (loss) per share on a pro forma basis for the year ended December 31, 2021 and 2020 would not have been materially different than our reported amounts. HAECO Special Services, LLC On March 1, 2021, our Federal and Defense segment acquired HAECO Special Services, LLC ("HSS") from HAECO Airframe Services, LLC, a division of HAECO Americas ("HAECO") for the purchase price of $14.8 million. HSS is a leading provider of fully integrated MRO support solutions for military and government aircraft. HSS provides scheduled depot maintenance, contract field deployment and unscheduled drop-in maintenance for a United States DoD contract specifically for the sustainment of the U.S. Air Force ("USAF") KC-10 fleet. HSS operating results are included in our Federal and Defense segment in the accompanying consolidated financial statements beginning on the acquisition date of March 1, 2021. The acquisition was not material to our consolidated financial statements. Divestitures Prime Turbines Sale In January 2020, VSE’s subsidiary VSE Aviation, Inc. entered into two definitive agreements to sell (1) Prime Turbines LLC ("Prime Turbines") and (2) certain related inventory assets to PTB Holdings USA, LLC ("PTB"). The transaction was completed on February 26, 2020 with cash proceeds of $20.0 million, including final working capital adjustments, and a note receivable of $8.3 million received as consideration. As a result of the sale of the business and inventory, we derecognized the assets and liabilities of Prime Turbines and recorded a $7.5 million loss in 2020 which is reflected within loss on sale of a business entity and certain assets in the consolidated statements of income.

A contract asset is a right to consideration that is conditional upon factors other than the passage of time. Contract assets include unbilled receivables and contract retentions but exclude billed receivables. Contract liabilities include customer advances, billings in excess of revenues and deferred revenue. Contract assets and liabilities are recorded net on a contract-by-contract basis and are generally classified as current based on our contract operating cycle. Receivables, net and unbilled receivables as of December 31, 2022 and 2021, respectively, were as follows (in thousands): 2022 2021 Receivables, net (1) $ 103,193 $ 76,587 Unbilled receivables 38,307 31,882 Total $ 141,500 $ 108,469 (1) Net of allowance of $2.1 million and $1.7 million as of December 31, 2022 and 2021, respectively. Unbilled receivables increased to $38.3 million as of December 31, 2022 from $31.9 million as of December 31, 2021, primarily due to revenue recognized in excess of billings. Contract liabilities, which are included in accrued expenses and other current liabilities in our consolidated balance sheet, were $6.4 million as of December 31, 2022 and $7.1 million as of December 31, 2021. For the year ended December 31, 2022 and 2021, we recognized revenue of $3.9 million and $5.1 million, respectively, that was previously included in the beginning balance of contract liabilities. Performance Obligations Our performance obligations are satisfied either at a point in time or over time as work progresses. Revenues from products and services transferred to customers at a point in time are primarily related to the sales of vehicle and aircraft parts in our Fleet and Aviation segments. Revenue recognized at a point in time accounted for approximately 59% and 54% of our revenues for the year ended December 31, 2022 and 2021, respectively. Revenues from products and services transferred to customers over time are primarily related to revenues in our Federal and Defense segment and MRO services in our Aviation segment. Revenues recognized over time accounted for approximately 41% and 46% of our revenues for the year ended December 31, 2022 and 2021, respectively. As of December 31, 2022, the aggregate amount of transaction prices allocated to unsatisfied or partially unsatisfied performance obligations was $187 million. Performance obligations expected to be satisfied within one year and greater than one year are 97% and 3%, respectively. We have applied the practical expedient for certain parts sales and MRO services to exclude the amount of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which we recognize revenue in proportion to the amount we have the right to invoice for services performed. During the year ended December 31, 2022, revenue recognized from performance obligations satisfied in prior periods was not material.

Interest expense incurred on bank credit facilities was approximately $17.4 million, $11.2 million and $12.7 million for the years ended December 31, 2022, 2021 and 2020, respectively. We have a loan agreement with a group of banks from which we borrow amounts under the loan agreement to provide working capital support, fund letters of credit, and finance acquisitions. The loan agreement includes term and revolving loan facilities. The revolving loan facility provides for revolving loans and letters of credit. The maximum amount of credit available under the loan agreement for revolving loans and letters of credit is $350 million. 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 $100 million subject to lender approvals. The loan agreement also provides for letters of credit aggregating up to $25 million. As of December 31, 2022 and 2021, we had approximately $1.0 million in letters of credit outstanding. On October 7, 2022, we entered into the Fourth Amendment to our loan agreement which, among other things, (i) extended the maturity date from July 23, 2024 to October 7, 2025; (ii) reset the aggregate principal amount of the term loan to $100 million, (iii) modified the quarterly amortization payments on the term loan from $3.75 million to $2.50 million, (iv) increased the maximum Total Funded Debt to EBITDA Ratio from 4.25x to 4.50x, with such ratios decreasing thereafter, (v) changed the benchmark rate from LIBOR to Secured Overnight Financing Rate (SOFR) with a SOFR floor of 0%; and (vi) modified pricing to account for the change from LIBOR to SOFR. Borrowings under our loan agreement bear interest at a variable rate of interest based on Term SOFR or a base rate, plus in each case an applicable margin (based on our Total Funded Debt to EBITDA Ratio). The base rate for any day is a fluctuating rate per annum equal to the highest of (i) the Federal Funds Rate plus .50%; (ii) the Prime Rate and (iii) the sum of Term SOFR for a one month interest period, plus the difference between the additional Term SOFR interest margin for SOFR rate loans and the additional base rate interest margin for base rate loans. The applicable margins for SOFR loans ranges from 1.50% to 3.75% and .50% to 2.75% for base rate loans. We also pay a commitment fee with respect to undrawn amounts under the revolving loan facility ranging from .25% to .50% (based on our Total Funded Debt to EBITDA Ratio) and fees on letters of credit that are issued. We incurred and deferred $1.1 million of debt issuance costs in connection with the Fourth Amendment to our loan agreement, which are amortized to interest expense over the remaining term of the loan. Amortization of debt issuance costs was $1.0 million, $1.0 million, $1.1 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Share-Based Payment Arrangement, Noncash Expense [Abstract]
Stock-Based Compensation Plans	Stock-Based Compensation Plans The VSE Corporation 2006 Restricted Stock Plan, as amended (the "2006 Plan"), provides VSE's employees and directors the opportunity to receive various types of stock-based compensation and cash awards. In May 2020, the stockholders approved amendments to the 2006 Plan extending its term until May 6, 2027 and authorizing an additional 500,000 shares of our common stock for issuance under the 2006 Plan. As of December 31, 2022, we are authorized to issue up to 1,500,000 shares of our common stock and 598,637 shares remained available for issuance. As of December 31, 2022, we have outstanding stock-settled bonus awards, vesting stock awards, and performance share awards under this plan. Stock-settled bonus awards are a fixed dollar-denominated award that vests over a three-year service period in three equal tranches. As each tranche vests, the fixed dollar value of the vested portion of the award is converted into shares based on the closing market price of our stock at the date of conversion. On each vesting date, 100% of the vested award is paid in stock that is subject to a two-year stock sales restriction. Expense is recognized on a straight-line basis over the requisite service period for each tranche, which results in an accelerated pattern for an award. Employee vesting stock awards generally vest over a three-year service period in equal installments on each anniversary of the grant date. Our directors receive a grant of vesting stock annually as part of their compensation and the stock vests immediately upon grant. We grant performance share awards to certain employees under the 2006 Plan. Performance share awards are rights to receive shares of our stock on the satisfaction of service requirements and performance conditions. These awards vest ratably in equal installments over a three-year period on the anniversary of each grant date, subject to meeting the minimum service requirements and the achievement of certain annual or cumulative financial metrics of our performance, with the number of shares ultimately issued, if any, ranging up to 100% of the specified target shares. If performance is below the minimum threshold level of performance, no shares will be issued. For all performance share awards granted, the annual and cumulative financial metrics are based on our achievement of a return on equity. During fiscal 2021, we established the Employee Stock Purchase Plan (ESPP) to allow eligible employees to purchase shares of our VSE common stock at a discount of up to 15% of the fair market value on specified dates. For ESPP offerings in the year ended December 31, 2022, the purchase price was 12% off the lesser of the fair market value on the date of the offering and the fair market value on the date of purchase, thereby resulting in stock compensation expense of $123 thousand. As of December 31, 2022, 500,000 shares of VSE common stock are authorized for issuance under the ESPP. Expense and Related Tax Benefits Recognized Stock-based compensation expense and related tax benefits recognized under the 2006 Plan for the years ended December 31, was as follows (in thousands): 2022 2021 2020 Stock-settled bonus awards $ 1,186 $ 820 $ 1,265 Vesting stock awards 2,089 2,273 1,593 Performance share awards 1,067 784 — Total $ 4,342 $ 3,877 $ 2,858 Tax benefit recognized from stock-based compensation $ 1,083 $ 967 $ 713 Stock-Settled Bonus Awards In March 2022, the employees eligible for the 2021 awards, 2020 awards and 2019 awards received a total of 21,871 shares of common stock. The grant-date fair value of these awards was $43.30 per share.

In 2020, we closed on a sale-leaseback agreement involving land and an office building utilized by our Aviation segment to conduct operations in Miami, Florida. Under the agreement, the land and building, with a net book value of $1.3 million was sold for a sale price of $2.6 million and leased back under a 6-year term operating lease commencing upon the closing of the transaction. The lease provides us with an option to extend the lease upon the expiration of its term in April 2026 for two additional five-year periods. In connection with the sale and leaseback transaction, we recognized a gain of $1.1 million, net of selling expenses.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesWe 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 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 audit or investigate whether our operations are being conducted in accordance with applicable contractual and regulatory requirements. Government audits or 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, audits and investigations will not have a material adverse effect on our results of operations, financial condition or cash flows.

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]
Business Segments and Customer Information	Business Segments and Customer Information Segment Information Management of our business operations is conducted under three reportable operating segments: Aviation Our Aviation segment provides aftermarket repair and distribution services to commercial, business and general aviation, cargo, military and defense, and rotorcraft customers globally. Core services include parts distribution, engine accessory maintenance, MRO services, rotable exchange and supply chain services. Fleet Our Fleet segment provides parts, inventory management, e-commerce fulfillment, logistics, supply chain support and other services to support the commercial aftermarket medium- and heavy-duty truck market, the United States Postal Service ("USPS"), and the DoD. Core services include vehicle parts distribution, sourcing, IT solutions, customized fleet logistics, warehousing, kitting, just-in-time supply chain management, alternative product sourcing, and engineering and technical support. Federal and Defense Our Federal and Defense segment provides aftermarket MRO and logistics and sustainment services to improve operational readiness and extend the life cycle of military vehicles, ships and aircraft for the DoD, federal agencies and international defense customers. Core services include base operations support; procurement; supply chain management; vehicle, maritime and aircraft sustainment services; IT services and energy consulting. The operating segments reported below are our segments 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 inter-segment sales as these activities are eliminated in consolidation. Corporate expenses are primarily selling, general and administrative expenses not allocated to segments. Corporate assets are primarily cash, property and equipment and investments held in separate trust. Our segment information is as follows (in thousands): For the years ended December 31, 2022 2021 2020 Revenues Aviation $ 408,112 $ 247,852 $ 165,070 Fleet 261,336 233,532 242,170 Federal and Defense 280,314 269,469 254,419 Total revenues $ 949,762 $ 750,853 $ 661,659 Operating income (loss): Aviation $ 36,416 $ (14,373) $ (35,513) Fleet 23,911 20,426 26,659 Federal and Defense (805) 19,897 26,309 Corporate expenses (4,391) (4,430) (3,532) Operating income $ 55,131 $ 21,520 $ 13,923 Depreciation and amortization expense: Aviation $ 13,174 $ 11,374 $ 10,874 Fleet 8,783 9,679 10,260 Federal and Defense 3,613 4,547 3,001 Total depreciation and amortization $ 25,570 $ 25,600 $ 24,135 Capital expenditures: Aviation $ 5,961 $ 7,468 $ 3,445 Fleet 5,502 1,669 675 Federal and Defense 26 124 148 Corporate 1,162 1,259 159 Total capital expenditures $ 12,651 $ 10,520 $ 4,427 December 31, 2022 2021 Total assets: Aviation $ 637,615 $ 580,156 Fleet 218,138 182,089 Federal and Defense 93,728 92,571 Corporate 50,308 63,742 Total assets $ 999,789 $ 918,558 Customer Information Our revenues are derived from the delivery of products and services performed for commercial customers and the U.S. government, including the DoD and various other government agencies. The USPS revenues, reported within our Fleet segment, comprised approximately 16%, 20%, and 27% of our consolidated revenues in 2022, 2021 and 2020, respectively. U.S. Navy revenues, reported within our Federal and Defense segment, comprised approximately 15%, 13%, and 16% of our consolidated revenues in 2022, 2021 and 2020, respectively. Our customers also include various other commercial entities and government agencies. See Note (3) "Revenue Recognition" for revenue by customer. We do not measure revenue or profit by product or service lines, either for internal management or external financial reporting purposes, because it would be impractical to do so. Products offered and services performed are determined by contract requirements and the types of products and services provided for one contract bear no relation to similar products and services provided on another contract. Products and services provided vary when new contracts begin or current contracts expire. In many cases, more than one product or service is provided under a contract or contract task order. Accordingly, cost and revenue tracking are designed to best serve contract requirements and segregating costs and revenues by product or service lines in situations for which it is not required would be difficult and costly to both us and our customers. Geographical Information Revenue by geography is based on the billing address of the customer. Our revenue by geographic area is as follows (in thousands): Years ended December 31, 2022 2021 2020 United States $ 837,929 $ 668,892 $ 598,142 Other Countries (1) 111,833 81,961 63,517 Total revenue $ 949,762 $ 750,853 $ 661,659 (1) No individual country, other than disclosed above, exceeded 10% of our total revenue for any period presented .

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We utilize fair value measurement guidance prescribed by GAAP to value our financial instruments. The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than the quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). The carrying amounts of cash and cash equivalents, receivables, accounts payable and amounts included in other current assets and accrued expenses and other current liabilities that meet the definition of a financial instrument approximate fair value due to their relatively short maturity. The carrying value of our outstanding debt obligations approximates its fair value. The fair value of long-term debt is calculated using Level 2 inputs based on interest rates available for debt with terms and maturities similar to our existing debt arrangements. Non-financial assets acquired and liabilities assumed in business combinations were measured at fair value using income, market and cost valuation methodologies. See Note (2), "Acquisitions and Divestitures." The fair value measurements were estimated using significant inputs that are not observable in the market and thus represent a Level 3 measurement. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2022 and December 31, 2021 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 December 31, 2022 Fair Value December 31, 2021 Non-COLI assets held in Deferred Supplemental Compensation Plan (1) Other assets Level 1 $ 539 $ 598 Interest rate swaps Other assets Level 2 $ 6,620 $ — Interest rate swaps Accrued expenses and other current liabilities Level 2 $ — $ 234 Earn-out obligation - short-term Accrued expenses and other current liabilities Level 3 $ — $ 1,000 Earn-out obligation - long-term Other long-term liabilities Level 3 $ — $ 250 (1) Non-COLI assets held in our 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. Contingent Consideration In connection with the acquisition of Global Parts in July 2021, we were required to make earn-out obligation payments of up to $2.0 million should Global Parts meet certain financial targets during the twelve months following the acquisition and meet a certain milestone event on or before March 2023. Final settlement of the obligation was made during the third quarter of fiscal 2022.

Nature of Business and Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of PresentationThe consolidated financial statements consist of the operations of our parent company and our wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States ("U.S. GAAP") requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies 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 may include, but are not limited to, fair value measurements, inventory provisions, collectability of receivables, estimated profitability of long-term contracts, valuation allowances on deferred tax assets, fair value of goodwill and other intangible assets and contingencies.
Stock-Based Compensation	Stock-Based Compensation We issue stock-based awards as compensation to employees and directors. Stock-based awards include stock-settled bonus awards, vesting stock awards and performance share awards. We recognize stock-based compensation expense over the underlying award’s requisite service period, as measured using the award’s grant date fair value. Our policy is to recognize forfeitures as they occur. For performance share awards, we assess the probability of achieving the performance conditions at each reporting period end and adjust compensation expense based on the number of shares we expect to ultimately issue.
Earnings Per Share	Earnings Per Share Basic earnings per share ("EPS") is 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 the assumed vesting of outstanding stock-based awards. As a result of incurring a net loss for the year ended December 31, 2020, potential dilutive shares were excluded from diluted loss per share as the effect would have been anti-dilutive. The antidilutive common stock equivalents excluded from the diluted per share calculation were not material.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Due to the short maturity of these instruments, the carrying values on our consolidated balance sheets approximate fair value.
Property and Equipment	Property and EquipmentProperty and equipment is recorded at cost, net of accumulated depreciation and amortization. Depreciation and amortization is generally provided on the straight-line method over the estimated useful lives of the various assets. Property and equipment is generally depreciated over the following estimated useful lives: computer equipment, furniture, other equipment from three
Leases	Leases We determine at inception whether an arrangement that provides us control over the use of an asset is a lease. Substantially all of our leases are long-term operating leases for facilities with fixed payment terms. We recognize a right-of-use ("ROU") asset and a lease liability upon commencement of our operating leases. The initial lease liability is equal to the future fixed minimum lease payments discounted using our incremental borrowing rate, on a secured basis. The lease term includes option renewal periods and early termination payments when it is reasonably certain that we will exercise those rights. The initial measurement of the ROU asset is equal to the initial lease liability plus any initial indirect costs and prepayments, less any lease incentives. We recognize lease costs on a straight-line basis over the remaining lease term, except for variable lease payments that are expensed in the period in which the obligation for those payments is incurred. Leases with an initial term of 12 months or less with purchase options or extension options that are not reasonably certain to be exercised are not recorded on the balance sheet. Operating lease cost is included in costs and operating expenses on our consolidated statement of income.
Concentration of Credit Risk	Concentration of Credit RiskFinancial instruments that potentially subject us to concentration of credit risk consist primarily of our trade receivables. Our trade receivables consist of amounts due from various commercial entities and government clients. We believe that concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the customer base and their dispersion across many different geographic regions. Contracts with the government, either as a prime or subcontractor, accounted for approximately 47%, 57%, and 69% of revenues for the years ended December 31, 2022, 2021 and 2020, respectively. The credit risk, with respect to contracts with the government, is limited due to the creditworthiness of the respective governmental entity. We perform ongoing credit evaluations and monitoring of the financial condition of all our customers. We maintain an allowance for credit losses based upon several factors, including historical collection experience, current aging status of the customer accounts and financial condition of our customers.
Revenue Recognition	Revenue Recognition We account for revenue in accordance with ASC 606. The unit of account in ASC 606 is a performance obligation. At the inception of each contract with a customer, we determine our performance obligations under the contract and the contract's transaction price. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the respective goods or services is not separately identifiable from other promises in the contracts and is, therefore, not distinct. For product sales, each product sold to a customer typically represents a distinct performance obligation. Our performance obligations are satisfied over time as work progresses or at a point in time based on transfer of control of products and services to our customers. Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for goods or services that are not distinct, and therefore are accounted for as part of the existing contract. Substantially all our Fleet segment revenues from the sale of vehicle parts to customers are recognized at the point in time of the transfer of control to the customer. Sales returns and allowances for vehicle parts are not significant. Our Aviation segment revenues result from the sale of aircraft parts and performance of MRO services for private and commercial aircraft owners, other aviation MRO providers, and aviation original equipment manufacturers. Our Aviation segment recognizes revenues for the sale of aircraft parts at a point in time when control is transferred to the customer, which usually occurs when the parts are shipped. Our Aviation segment recognizes revenues for MRO services over time as the services are transferred to the customer. MRO services revenue recognized is measured based on the cost-to-cost input method, as costs incurred reflect the work completed, and therefore the services transferred to date. Sales returns and allowances are not significant. Our Federal and Defense segment revenues result from professional and technical services, which we perform for customers on a contract basis. Revenue is recognized for performance obligations over time as we transfer the services to the customer. The three primary types of contracts used are cost-type, fixed-price and time-and-materials. Revenues result from work performed on these contracts by our employees and our subcontractors and from costs for materials and other work-related costs allowed under our contracts. Revenues on cost-plus contracts are recorded as contract allowable costs are incurred and fees are earned. Variable consideration is included in the estimated transaction price, to the extent that it is probable that a significant reversal will not occur, when there is a basis to reasonably estimate the amount of the fee. These estimates are based on historical award experience, anticipated performance and our best judgment based on current facts and circumstances. Revenues on fixed-price contracts are recorded as work is performed over the period. We generally recognize revenue using the time-elapsed output method for our fixed-price service offering performance obligations. For certain deliverable-based fixed-price performance obligations, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion. For such contracts, we estimate total costs at the inception of the contract based on our assumptions of the cost elements required to complete the associated tasks of the contract and assess the impact of the risks on our estimates of total costs to complete the contract. Our cost estimates are based on assumptions that include the complexity of the work, our employee labor costs, the cost of materials and the performance of our subcontractors. These cost estimates are subject to change as we perform under the contract and as a result, the timing of revenues and amount of profit on a contract may change as there are changes in estimated costs to complete the contract. Such adjustments are recognized on a cumulative catch-up basis in the period we identify the changes. Revenues for time and materials ("T&M") contracts are recorded based on the amount for which we have the right to invoice our customers, because the amount directly reflects the value of our work performed for the customer. Revenues are recorded on the basis of contract allowable labor hours worked multiplied by the contract defined billing rates, plus the direct costs and indirect cost burdens associated with materials and subcontract work used in performance on the contract. Generally, profits on time and materials contracts result from the difference between the cost of services performed and the contract defined billing rates for these services. Revenues related to work performed on government contracts at risk, which is work performed at the customer's request prior to the government formalizing funding, is not recognized until it can be reliably estimated, and its realization is probable. A substantial portion of contract and administrative costs are subject to audit by the Defense Contract Audit Agency. Our indirect cost rates have been audited and approved for 2021 and prior years with no material adjustments to our results of operations or financial position. While we maintain reserves to cover the risk of potential future audit adjustments based primarily on the results of prior audits, we do not believe any future audits will have a material adverse effect on our results of operations, financial position, or cash flows.
Receivables and Unbilled Receivables	Receivables and Unbilled Receivables Receivables are recorded at amounts earned less an allowance. We review our receivables regularly to determine if there are any potentially uncollectible accounts. The majority of our receivables are from government agencies, where there is minimal credit risk. Unbilled receivables include amounts typically resulting from sales under contracts when the cost-to-cost method of revenue recognition is utilized, and revenue recognized exceeds the amount billed to the customer. The amounts may not exceed their estimated net realizable value. Unbilled receivables are classified as current based on our contract operating cycle.
Allowance for Credit Losses	Allowance for Credit Losses We establish allowances for credit losses on our accounts receivable and unbilled receivables. To measure expected credit losses, we have disaggregated pools of receivable balances by segment. Within each segment, receivables exhibit similar risk characteristics. In determining the amount of the allowance for credit losses, we consider historical collectability based on past due status. We also consider current market conditions and forecasts of future economic conditions to inform potential
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value using the first-in, first-out ("FIFO") method. Inventories consist primarily of finished goods replacement parts for our Fleet and Aviation segments, and also include related purchasing, storage and handling costs. Inventories for our Aviation segment consist primarily of aftermarket parts for distribution, and general aviation engine accessories and parts, and also include related purchasing, overhaul labor, storage and handling costs.
Deferred Compensation Plans	Deferred Compensation Plans We established the VSE Corporation Deferred Supplemental Compensation Plan ("DSC Plan") for the benefit of certain key management employees to be incentivized and rewarded based on overall company performance. We recognized DSC Plan expenses of $0.3 million, $0.4 million and $1.0 million for the years ended December 31, 2022, 2021 and 2020, respectively.
Derivatives Instruments	Derivative InstrumentsDerivative instruments are recorded on the consolidated balance sheets at fair value. Unrealized gains and losses on derivatives designated as cash flow hedges are report in other comprehensive income (loss) and reclassified into earnings in a manner that matches the timing of the earnings impact of the hedged transactions.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. This method also requires the recognition of future tax benefits, such as net operating loss carryforwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The carrying value of net deferred tax assets is based on assumptions regarding our ability to generate sufficient future taxable income to utilize these deferred tax assets.
Business Combinations	Business Combinations We allocate the purchase price of acquired entities to the underlying tangible and identifiable intangible assets acquired and liabilities assumed based on their respective estimated fair values, with any excess recorded as goodwill. The operating results of acquired businesses are included in our results of operations beginning as of their effective acquisition dates. For contingent
Goodwill	Goodwill and Other Intangible Assets Goodwill represents the purchase price paid in excess of the fair value of net tangible and intangible assets acquired in a business combination. Goodwill is tested for potential impairment at the reporting unit level annually at the beginning of the fourth quarter, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
Intangibles Assets	Intangible assets with finite lives are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives.  Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
Impairment of Long-Lived Assets (Excluding Goodwill)	Impairment of Long-Lived Assets (Excluding Goodwill) We review our long-lived assets, including amortizable intangible assets and property and equipment, for impairment whenever events or changes in facts and circumstances indicate that their carrying values may not be fully recoverable. We assess impairment by comparing the estimated undiscounted future cash flows of the related asset to its carrying value. If an asset is determined to be impaired, we recognize an impairment charge in the current period for the difference between the fair value of the asset and its carrying value.
Recently Adopted Accounting Pronouncements	Recent Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, "Revenue from Contracts with Customers," as if the acquirer had originated the contracts. The new standard is effective on a prospective basis for fiscal years and interim reporting periods within those fiscal years beginning after December 15, 2022, with early adoption permitted. We elected to early adopt this standard during the first quarter 2022 and will apply the guidance prospectively to business combinations entered into subsequent to adoption.
