The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a pneumatic accumulator, identified by NSN 7R-2530-014183271-V2. The procurement involves a quantity of 134 units, with delivery terms set to FOB Origin, and requires engineering source approval to ensure the quality of the parts, as they are flight critical. Interested vendors must be approved sources or provide detailed documentation for source approval, as the government intends to negotiate with only one source under FAR 6.302-1. Proposals must be submitted within 45 days of the notice, and interested parties can contact Jake Kucowski at (215) 679-2012 or via email at JAKE.KUCOWSKI.CIV@US.NAVY.MIL for further information.
