The Department of Defense, through the Defense Logistics Agency, is seeking proposals for the procurement of 116 units of the Head Hydraulic Motor (NSN: 1650-01-209-5072HS) for the B-1 aircraft, with a presolicitation notice issued under SPRTA1-25-R-0028. This sole source acquisition is critical for maintaining the operational readiness of military aircraft, and the government intends to negotiate with Hamilton Sundstrand, the qualified source that previously supplied these parts. Proposals must be submitted by November 25, 2024, with delivery expected by January 27, 2025, and interested parties can reach out to John Nolan at john.nolan.8@us.af.mil or call 405-855-3542 for further inquiries.
