The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a Handset Assembly (NSN 7R-6650-016076886-SX, REF NR 815430-20) with a quantity of 2 each. This item is classified as flight critical, necessitating government source approval prior to contract award, as the technical data available does not support full and open competition. Interested vendors 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 understanding that the government may proceed with award based on fleet support needs if source approval cannot be processed in time. For further inquiries, interested parties can contact Connor C. Lewis at (215) 697-4757 or via email at CONNOR.C.LEWIS@NAVY.MIL.
