The Department of Defense, through the Naval Supply Systems Command (NAVSUP) Weapon Systems Support, is seeking to procure 25 units of a Receiver Transmitter (Part Number: P600A438-50) under a sole source contract. This procurement is based on the National Stock Number (NSN) 7R-5821-016637465, and the Government intends to negotiate with only one source due to the specific nature of the item, which is critical for airborne radio and television communication equipment. Interested parties are encouraged to express their interest and capability to fulfill this requirement, although the Government reserves the right to proceed with a sole source award if no competitive proposals are received within 45 days of the notice. For further inquiries, Stacey Ryan can be contacted at (215) 697-1255 or via email at STACEY.RYAN@NAVY.MIL.
