The Department of Defense, specifically the Department of the Navy, is seeking proposals for the procurement of 10 units of a power supply, identified by NSN 7H-6130-014989066, under a presolicitation notice. The contract is set aside for small businesses and will be negotiated with only one source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive bidding. The power supply is critical for military applications, and interested parties must submit their capabilities within 45 days of the notice, with the primary contact for inquiries being Benjamin Speros at (717) 605-5150 or via email at BENJAMIN.SPEROS@NAVY.MIL.
