Segment Reporting [Abstract]  
Segment Information Segment Information
Operating segments represent components of an enterprise for which separate financial information is available that is regularly reviewed by the CODM in determining how to allocate resources and assess performance. The Company’s operating and reportable segments consist of ASC and IMS. All other operations, which consists primarily of DRS corporate headquarters and certain non-operating subsidiaries of the Company, are grouped in Corporate & Eliminations.
The CODM primarily uses operating earnings to manage the Company and allocate resources. Operating earnings is used to facilitate a comparison of the ordinary, ongoing and customary course of our operations on a consistent basis from period to period and provide an additional understanding of factors and trends affecting our business segments.
Certain information related to our segments for the periods ended June 30, 2026 and 2025 is presented in the following tables. Consistent accounting policies have been applied by all segments within the Company, within all reporting periods. Intersegment sales are generally transferred at cost to the buying segment, and the sourcing segment does not recognize a profit. Such intercompany operating earnings is eliminated in consolidation, so that the Company’s total revenues and operating earnings reflect only those transactions with external customers.
