The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of circuit card assemblies, identified by NSN 7R-5998-013123188-EY, with a quantity of four units required for delivery FOB origin. This procurement is critical as the item is flight critical, necessitating engineering source approval from the design control activity to ensure quality and compliance with established standards. 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, with proposals due within 45 days of the notice. For further inquiries, interested parties can contact Danielle M. Junod at (215) 697-1138 or via email at DANIELLE.M.JUNOD.CIV@US.NAVY.MIL.
