The Department of Defense, specifically the Department of the Navy, is seeking proposals for the repair and modification of compressor units under a presolicitation notice. The procurement involves three units of the NSN 7H-4310-014721365, which are critical components for military operations, and the government intends to negotiate with only one source due to the unavailability of necessary data for competitive procurement. Interested parties are encouraged to express their interest and capability to fulfill the requirement within 45 days of the notice, with all inquiries directed to Kristina Alexander at (717) 605-6055 or via email at KRISTINA.ALEXANDER@NAVY.MIL.
