The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure six units of the ARM Assembly, Torque, identified by NSN 7R-1620-014553638-QE. This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data for the part is not sufficiently available for open competition. Interested parties must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with contact inquiries directed to Jessica L. Harpel at jessica.harpel@navy.mil. The government intends to negotiate with only one source under FAR 6.302-1, emphasizing the importance of compliance with qualification requirements for award consideration.
