Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and in accordance with the instructions to SEC Form 10-Q and Article 10 of SEC Regulation S-X. Therefore, such financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and footnotes thereto included in our 2020 Form 10-K. 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 six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2021. The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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, award fee revenues, costs to complete on fixed price contracts, and recoverability of goodwill and intangible assets. Coronavirus (COVID-19) Pandemic On March 11, 2020, the World Health Organization declared the outbreak of the novel coronavirus disease, known as COVID-19, as a global pandemic. The pandemic and the containment and mitigation efforts by governments to attempt to control its spread created uncertainties and disruptions in the economic and financial markets. The pandemic triggered a decline in demand for our Aviation segment products and services beginning with the second quarter of 2020 and continuing through the end of the second quarter of 2021. Our results of operations for the first six months of 2021 continue to reflect the adverse impact from the COVID-19 pandemic. Although demand has improved since the onset of the pandemic, it remains below pre-pandemic levels. The extent to which the impact of COVID-19 may continue to have an adverse effect on our future business and results of operations is highly uncertain and unpredictable. However, we believe that with the global vaccination effort underway, that may generate an increase in commercial air travel and result in a gradual recovery in demand for our Aviation segment products and services commencing toward the second half of 2021. We are closely monitoring the effects and risks of COVID-19 to assess its continuing impact on our business, financial condition and results of operations. We maintain a robust continuity plan to adequately respond to situations such as the COVID-19 pandemic, including a framework for remote work arrangements, in order to effectively maintain operations, including financial reporting systems, internal controls over financial reporting and disclosure controls and procedures.

Business Combination and Asset Acquisition [Abstract]
Acquisition and Divestitures	Acquisition and Divestitures Acquisition On March 1, 2021, we 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, subject to post-closing and working capital adjustments. HSS is a leading provider of fully integrated maintenance, repair and overhaul ("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 Department of Defense ("DoD") contract specifically for the sustainment of the U.S. Air Force ("USAF") KC-10 fleet. The acquisition was not significant to our consolidated financial statements. HSS operating results are included in our Federal and Defense segment in the accompanying unaudited consolidated financial statements beginning on the acquisition date of March 1, 2021. 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 the first quarter of 2020 which was reflected within loss on sale of a business entity and certain assets in the consolidated statements of income. As of June 30, 2021 and December 31, 2020, the total outstanding balance of the note receivable from PTB was $5.4 million and $6.1 million, respectively, which represent the present value of the consideration to be received with an imputed interest rate discount, of which $1.5 million and $1.4 million were current as of June 30, 2021 and December 31, 2020, respectively. The note receivable balance is included in other assets and other current assets in our consolidated balance sheets. CT Aerospace Asset Sale

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregated Revenue Our revenues are derived from the delivery of products to our customers and from contract services performed for the DoD or federal civilian agencies. Our customers also include various other government agencies and commercial clients.

Contract liabilities are recorded when customers remit contractual cash payments in advance of us satisfying related performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. We present our unbilled receivables and contract liabilities on a contract-by-contract basis. If a contract liability exists, it is netted against the unbilled receivables balance for that contract. Unbilled receivables increased from $22.4 million at December 31, 2020 to $30.7 million at June 30, 2021, primarily due to the unbilled receivables acquired as a result of the HSS acquisition and revenues recognized as performance obligations are satisfied in excess of billings. Contract liabilities, which are included in accrued expenses and other current liabilities in our consolidated balance sheets, increased from $10.1 million at December 31, 2020 to $12.7 million at June 30, 2021, primarily due to advance payments received in excess of revenue recognized. For the six months ended June 30, 2021 and June 30, 2020, we recognized revenue that was previously included in the beginning balance of contract liabilities of $1.7 million and $1.5 million, respectively. Performance Obligations Our performance obligations are satisfied either at a point in time or over time as work progresses. The majority of our revenue recognized at a point in time is for the sale of vehicle and aircraft parts in our Fleet and Aviation segments. Revenues from products and services transferred to customers at a point in time accounted for approximately 49% of our revenues for the three and six months ended June 30, 2021 and 50% of our revenues for the three and six months ended June 30, 2020. Revenues from products and services transferred to customers over time accounted for approximately 51% of our revenues for the three and six months ended June 30, 2021 and 50% of our revenues for the three and six months ended June 30, 2020, primarily related to revenues in our Federal and Defense segment and MRO services in our Aviation segment. As of June 30, 2021, the aggregate amount of transaction prices allocated to unsatisfied or partially unsatisfied performance obligations was $224 million. Performance obligations expected to be satisfied within one year and greater than one year are 90% and 10%, 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 six months ended June 30, 2021 and June 30, 2020, revenue recognized from performance obligations satisfied in prior periods was not material.

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 fair value of outstanding debt as of June 30, 2021 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. Our required term and revolver loan payments after June 30, 2021 are as follows (in thousands): 2021 11,250 2022 22,500 2023* 243,233 Total $ 276,983 *Includes the revolver loan required payment of $209.3 million. The maximum amount of credit available under the loan agreement for revolving loans and letters of credit as of June 30, 2021 was $350 million. We pay an unused commitment fee and fees on letters of credit that are issued. We had $803 thousand letters of credit outstanding as of June 30, 2021 and no letters of credit outstanding as of December 31, 2020. 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. 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 June 30, 2021, the LIBOR base margin was 2.25% and the base rate base margin was 1.00%. The base margins increase or decrease in increments as our Total Funded Debt/EBITDA Ratio increases or decreases. We use interest rate hedges on a portion of our debt. The amount of our debt with interest rate swap agreements was $75 million and $145 million as of June 30, 2021 and December 31, 2020, respectively. After taking into account the impact of interest rate swap agreements, as of June 30, 2021, interest rates on portions of our outstanding debt ranged from 3.00% to 5.61%, and the effective interest rate on our aggregate outstanding debt was 3.44%. Interest expense incurred on bank loan borrowings and interest rate hedges was approximately $2.4 million and $2.8 million for the three months ended June 30, 2021 and 2020, respectively, and $5.1 million and $6.3 million for the six months ended June 30, 2021 and 2020, respectively. The loan agreement contains collateral requirements to secure our 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 to EBITDA Ratio and a minimum Fixed Charge Coverage Ratio. We were in compliance with required ratios and other terms and conditions as of June 30, 2021. We continue to monitor the impacts of COVID-19 on our results of operations and liquidity relative to compliance with financial covenants; at this time, we expect that we will remain in compliance with such covenants over the next twelve months. Subsequent Event In July 2021, we entered into a third amendment to our loan agreement which, among other things, extended the maturity dates with respect to the revolving credit facility and term loan facility to July 2024, lowered the applicable LIBOR rate floor, and modified the maximum Total Funded Debt to EBITDA Ratio. After the amendment, our required term and revolver loan payments after June 30, 2021 are approximately $7.5 million in 2021, $15.0 million in 2022, $15.0 million in 2023, and $239.5 million in 2024. We classified the current portion of long-term debt in our consolidated balance sheets as of June 30, 2021 based on the amended terms. Except as described above, the amended loan agreement has substantially the same terms as the existing loan agreement, including covenants and events of default.

Earnings Per Share [Abstract]
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 an assumed vesting of restricted stock awards. For the three and six months ended June 30, 2021 and 2020, diluted earnings per share does not include an adjustment for the potential dilutive effect of dilutive securities as the effect would have been anti-dilutive due to the Company's net loss. The anitdilutive common stock equivalents excluded from the diluted per share calculation are not material.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies 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 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.

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 intersegment sales as these activities are eliminated in consolidation. Corporate expenses are primarily selling, general and administrative expenses not allocated to segments.

The inventory reserve increase was primarily due to excess quantities of inventory at levels higher than our updated forecasts of future demand. The continued effects of the COVID-19 pandemic on commercial air travel for our region specific distribution programs, entered into prior to 2019, resulted in lowered demand assumptions.

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 June 30, 2021 and December 31, 2020 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 June 30, 2021 Fair Value December 31, 2020 Non-COLI assets held in Deferred Supplemental Compensation Plan Other assets Level 1 $ 1,276 $ 1,120 Interest rate swap agreements Accrued expenses Level 2 $ 720 $ 1,603 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. 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. We evaluate our hedges to determine their effectiveness and as of June 30, 2021 and December 31, 2020, the swaps were determined to be fully effective. Accordingly, the fair value of the swap agreements, which is a liability recorded in accrued expenses and other current liabilities in our consolidated balance sheets, was approximately $720 thousand and $1.6 million at June 30, 2021 and December 31, 2020, respectively. The offset, net of an income tax effect of approximately $180 thousand and $400 thousand, was included in accumulated other comprehensive income in the accompanying balance sheets as of June 30, 2021 and December 31, 2020, 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 expect the hedges to remain fully effective during the remaining terms of the swap agreements. We determine the fair value of the swap agreements based on a valuation model using primarily observable market data inputs.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesIncome 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. Our effective tax rate was 19.6% and 17.6% for the three and six months ended June 30, 2021, respectively, and 9.4% and (3.0)% for the three and six months ended June 30, 2020, respectively. The difference in the effective tax rate for the three and six months ended June 30, 2021 compared to the same period of prior year primarily results from 1) a significantly higher tax loss than book loss in connection with our sale of Prime Turbines stock and a full valuation allowance established in 2020 to offset the capital loss benefit due to a lack of anticipated capital gain income in the carryforward period, 2) goodwill impairment loss recognized in 2020 that was not deductible for tax purposes, and 3) larger book loss in 2020 compared to the same period in 2021. The tax rate for the current year benefited from tax deductions for foreign derived intangible income ("FDII") and COLI income, and various federal and state income tax incentives.

Subsequent Events	Subsequent Events Acquisition of Global Parts Group, Inc. In July 2021, we 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 will expand our existing B&GA focus beyond engine components to include the entire airframe. We anticipate this acquisition will further diversify our existing product and platform offerings, while expanding our customer base of regional and global B&GA customers. Global Parts will operate as a subsidiary of VSE Aviation, Inc. under our Aviation segment. The aggregate initial cash purchase price for Global Parts was approximately $38 million, subject to certain post-closing and working capital adjustments, which was funded using our existing bank revolving loan. We incurred approximately $215 thousand of acquisition-related expenses as of June 30, 2021 which are included in selling, general and administrative expenses.

Basis of Accounting	Our accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and in accordance with the instructions to SEC Form 10-Q and Article 10 of SEC Regulation S-X. Therefore, such financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and footnotes thereto included in our 2020 Form 10-K. 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 six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2021.
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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, award fee revenues, costs to complete on fixed price contracts, and recoverability of goodwill and intangible assets.
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 an assumed vesting of restricted stock awards.
