The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 9 units of a flight-critical fuel metering pump, identified by NSN 7R-2915-014545723-QE and reference number 9C124-2. This procurement requires government source approval prior to contract award, as the item is essential for aircraft and missile prime movers, and only previously approved sources will be considered for this solicitation. Interested vendors must submit detailed technical data and source approval information with their proposals, as offers lacking this documentation will not be evaluated. Proposals are due within 45 days of the notice publication, and interested parties should contact Jacob A. Tarlini at jacob.tarlini@navy.mil for further inquiries.
