The Department of Defense, specifically the Department of the Navy, is seeking proposals for the repair and modification of 14 units of a linear valve, identified by NSN 7H-4810-014906128. The procurement is limited to one source due to the government's determination that it is uneconomical to acquire the necessary data or rights for competitive sourcing, making this a non-competitive solicitation under FAR 6.302-1. The selected contractor will be required to deliver the repaired items within 180 days of contract award, with the solicitation number N00104-26-R-YA1S. Interested parties must submit their proposals to the primary contact, Taylor M.
