The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a signal converter (NSN 7R-5895-014593051-LU, REF NR MA834A-01) with a quantity of one unit, requiring delivery FOB origin. This procurement necessitates engineering source approval due to the flight-critical nature of the item, which mandates that only approved sources may submit proposals, as the technical data required for alternative sources is not readily available to the Government. Interested parties must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures to be considered, with a submission deadline of 45 days from the notice publication date. For further inquiries, potential bidders can contact Jose Montes at (215) 697-2558 or via email at JOSE.F.MONTES@NAVY.MIL.
