The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of the Interconnect PWA, AI, with a focus on a flight-critical item identified by NSN 7R-6150-015773461-H1. The procurement requires Government source approval prior to contract award due to the lack of available technical data and the critical nature of the item, which necessitates that only previously approved sources are solicited. Interested parties must submit detailed technical data and experience documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, with proposals due within 45 days of this notice. For further inquiries, interested vendors can contact Dina M. Wojciechowski at (215) 697-1219 or via email at DINA.M.WOJCIECHOWSKI.CIV@US.NAVY.MIL.
