The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure six units of the Manifold Assembly, H, under a sole source contract with Sikorsky Aircraft Corp. This procurement is specifically for a spare requirement identified by National Stock Number (NSN) 1R-1650-013454876-KH and Part Number 70652-02250-056, which is critical for aircraft hydraulic systems. The solicitation is expected to be issued on January 13, 2026, with a response deadline of February 12, 2026, and interested parties are encouraged to submit capability statements to the primary contact, Taylor M. O'Connor, via email at taylor.m.oconnor2.civ@us.navy.mil. This opportunity is not set aside for small businesses, and the government intends to negotiate with only one responsible source due to the specialized nature of the requirement.
