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 flight-critical antenna selector, identified by NSN 7R-5985-015855316-P8, with a quantity of 9 units required. This procurement necessitates government source approval prior to contract award, as the technical data available has not been deemed adequate for full and open competition, meaning only previously approved sources will be considered. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and failure to submit the required data will result in disqualification from the award process. For further inquiries, potential bidders can contact Connor C. Lewis at (215) 697-4757 or via email at CONNOR.C.LEWIS@NAVY.MIL.
