Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Acquisitions Acquisition of NorthStar Technologies, LLC ("NorthStar") On April 1, 2026, the Company acquired NorthStar, a provider of MRO services, third-party logistics, and kitting services supporting the engine aftermarket. The acquisition expands the Company’s engine service capabilities within business and general aviation and strengthens its OEM-focused strategy by enhancing integration within an engine OEM’s aftermarket supply chain and supporting growing demand for engine teardown and labor-intensive services. The acquisition is not material to the Company’s consolidated financial statements and was funded through existing sources of liquidity. The preliminary purchase price allocation has not yet been completed due to the limited time between the acquisition date and the issuance of these unaudited consolidated financial statements. Acquisition of Precision Aviation Group ("PAG" or "PAG Acquisition") On May 5, 2026, the Company completed its previously announced acquisition of PAG, a portfolio company of GenNx360 Capital Partners, for total upfront consideration of approximately $2.025 billion, consisting of $1.750 billion in cash and an in-kind payment in the form of 1,415,752 shares of newly issued equity of a VSE subsidiary, exchangeable for shares of the Company's common stock following an initial lock-up period. In addition, the stock purchase agreement provides for up to $125.0 million of contingent earn-out consideration, payable in cash or equity at the Company's sole discretion, based on PAG's 2026 adjusted EBITDA performance. The cash portion of the purchase price was funded through (i) net proceeds of approximately $1.3 billion from the Company’s public offerings of common stock and tangible equity units completed in February 2026 and (ii) borrowings under the New Term Facility. The acquisition expands the Company’s scale and enhances its engine and component service capabilities across the aviation aftermarket, while broadening its global customer base, increasing geographic reach, and strengthening its position as a leading provider of integrated MRO, repair, and supply chain solutions with differentiated technical and component-level capabilities. The preliminary purchase price allocation has not yet been completed due to the limited time between the acquisition date and the issuance of these unaudited consolidated financial statements. During the three months ended March 31, 2026, the Company incurred $4.5 million of PAG acquisition-related expenses, which are included in selling, general and administrative expenses. Credit Agreement Amendment On May 5, 2026, in connection with the PAG acquisition, the Company entered into a first amendment to its existing Credit Agreement, which provides for, among other things, a $900.0 million term loan B facility and an upsize of the Company's existing revolving credit facility from $400.0 million to $500.0 million, maturing on May 5, 2033 and May 2, 2030, respectively. See Note (5) "Debt" for further information.
