Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Nature of Operations VSE Corporation, through its subsidiaries (collectively, "VSE" or the "Company") is a diversified aftermarket products and services company serving commercial and government markets. The Company's operations include aircraft and airframe parts supply and distribution and maintenance, repair and overhaul ("MRO") services of aircraft engines and auxiliary power units, avionics, and airframe components and accessories. The Company operates as one reportable segment aligned with the Company's operating segment: Aviation. Basis of Presentation The Company's 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 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 the Company's Annual Report on Form 10-K for the year ended December 31, 2025 ("2025 Form 10-K"). In the Company's opinion, all adjustments, including normal recurring items, considered necessary for a fair presentation of results for the interim periods have been included in the accompanying unaudited consolidated financial statements. Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026. In February 2024, VSE entered into two separate agreements to sell substantially all of its Federal and Defense segment assets. Additionally, in April 2025, VSE completed the sale of all of the issued and outstanding shares of common stock of its Fleet segment. See Note (3) "Discontinued Operations" for further information. Certain reclassifications have been made to the prior year consolidated financial statements to conform to the current year presentation. Such reclassifications had no effect on the Company's previously reported results of operations. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company 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 fair value measurements, inventory provisions, collectability of receivables, valuation allowances on deferred tax assets, valuation and lives of tangible and intangible assets acquired from business combinations, and contingencies.
