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-5865-017059130-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 has not been deemed adequate for full and open competition, meaning only previously approved sources will be considered. The item is crucial for electronic countermeasures, and interested vendors must submit detailed information regarding their production capabilities and experience, as outlined in the NAVSUP WSS Source Approval Information Brochures. Proposals must be submitted to Sarah E. Crompton at NAVSUP WSS, with all required documentation included, to ensure consideration for the award. For further inquiries, interested parties can contact Sarah E. Crompton at (215) 697-5809 or via email at SARAH.CROMPTON@NAVY.MIL.
