The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two units of a flight-critical receiver, identified by NSN 7R-5865-017059130-P8 and reference number 131K832G05. This procurement requires government source approval prior to contract award, as the item is essential for operational capabilities and the technical data available does not support full and open competition. Interested vendors must provide comprehensive documentation demonstrating their qualifications and experience in producing similar items, as offers lacking the necessary source approval information will not be considered. For further inquiries, interested parties can contact Sarah E. Crompton at (215) 697-5809 or via email at SARAH.CROMPTON@NAVY.MIL.
