The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three units of the Gearbox Assembly, AI, identified by NSN 7R-1680-014921441-VH and part number 70357-06300-044. This procurement is critical as the Gearbox Assembly is an essential component for various aircraft systems, and the government intends to negotiate exclusively with Sikorsky Aircraft Corp, the Original Equipment Manufacturer (OEM), due to the lack of available drawings or data for alternative sources. Interested parties are encouraged to submit capability statements or proposals within 45 days of this notice, with the anticipated award date set for March 2024. For further inquiries, contact Anna M. Kiessling at (215) 697-3752 or via email at anna.m.kiessling.civ@us.navy.mil.
