The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the repair and modification of Receiver-Transmitter units. This procurement is a sole source requirement, necessitating that all repair efforts adhere strictly to established procedures and guidelines, as the government lacks sufficient data to engage alternative sources. The successful contractor will be responsible for ensuring that the units are returned to a Ready for Issue (RFI) condition, following comprehensive testing and inspection protocols. Interested parties must contact Cody Cameron at 215-697-1202 or via email at cody.p.cameron@navy.mil for further details, and proposals must remain valid for a minimum of 120 days post-submission.
