The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 34 units of a flight-critical oxygen regulator (NSN 7R-1660-015303498-FZ). This procurement requires government source approval prior to contract award, as the technical data available has not been deemed adequate for full and open competition, meaning only previously approved sources will be considered. Interested parties must submit detailed technical data and evidence of prior experience in producing similar items, as offers lacking the necessary documentation will not be considered. For further inquiries, potential bidders can contact Chris Campellone at (215) 697-2530 or via email at CHRISTOPHER.CAMPELLO@NAVY.MIL.
