The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a flight-critical receiver, identified by NSN 7R-5865-017083360-P8, with a quantity of one unit required for delivery FOB origin. This procurement necessitates government source approval prior to contract award, as the technical data available does not support full and open competition, meaning only previously approved sources will be considered for this solicitation. The item is crucial for electronic countermeasures, and interested vendors must submit detailed information regarding their production capabilities along with their proposals, as offers lacking the required documentation will not be considered. For further inquiries, potential bidders can contact Connor C. Lewis at (215) 697-4757 or via email at CONNOR.C.LEWIS@NAVY.MIL.
