The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a Selector Antenna, identified by NSN 7R-5985-015855316-P8, with a quantity of one unit required for delivery FOB origin. This procurement is critical as the item is flight critical, necessitating government source approval prior to contract award, and only previously approved sources will be considered for this solicitation. Interested vendors must provide comprehensive technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to submit the required information will result in disqualification from the award process. For further inquiries, interested parties can contact Connor C. Lewis at (215) 697-4757 or via email at CONNOR.C.LEWIS@NAVY.MIL.
