The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a flight-critical bolt, identified by NSN 1R-5305-LLF02I167-P8, with a quantity of one unit required for delivery FOB origin. This procurement is unique as it necessitates Government source approval prior to contract award due to the critical nature of the item and the inadequacy of available technical data for competitive solicitation. Interested vendors must ensure they are an approved source or submit the necessary documentation for source approval along with their proposals, as offers lacking required data will not be considered. For further inquiries, Danielle M. Junod can be contacted at (215) 697-1138 or via email at DANIELLE.M.JUNOD.CIV@US.NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
