The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a transmitter, part number 453-5000-366. This procurement involves a sole source requirement for two units of the transmitter, identified by NSN 7R-6610-015138405-KB, with delivery terms set to FOB Origin. The transmitter is critical for flight instrumentation, and the government does not possess sufficient data to contract with sources other than the current supplier. Interested vendors must ensure they are an approved source and submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. For inquiries, potential bidders can contact Samantha M. Freedman at (215) 697-6566 or via email at Samantha.M.Freedman.CIV@us.navy.mil.
