The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure an Antenna Assembly, identified by NSN 7R-5985-016740470-RQ, with a quantity of three units. This procurement is critical as the item is flight critical, and the government requires source approval prior to contract award due to the lack of adequate technical data for competitive solicitation. Interested vendors must submit the necessary documentation for source approval along with their proposals, as offers that do not comply with the requirements outlined in the Source Approval Information Brochure will not be considered. For further inquiries, interested parties can contact Carmelena C. Oldroyd at (215) 697-2606 or via email at CARMELENA.OLDROYD@NAVY.MIL, with proposals due within 45 days of the notice publication.
