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 display unit, identified by NSN 7R-7025-014764642-V2, with a quantity of 60 units required. This procurement necessitates engineering source approval due to the flight-critical nature of the item, which mandates that only previously approved sources may submit proposals, as the technical data necessary for full and open competition is not adequately available. Interested parties must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with the primary contact for inquiries being Gerard T. Weiss at GERARD.T.WEISS.CIV@US.NAVY.MIL.
