The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two compressor units for repair or modification under a presolicitation notice. The procurement involves a specific National Stock Number (NSN 7H-4310-015479404) and is limited to one source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive bidding. These compressor units are critical components within military operations, and the government intends to solicit and negotiate with only one source under FAR 6.302-1. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of the notice, with contact details provided for further inquiries to Hilary Garrett at (717) 605-2375 or via email at HILARY.GARRETT@NAVY.MIL.
