The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 25 units of audio frequency amplifiers and other replacement parts under the presolicitation notice. The procurement involves a specific National Stock Number (NSN 7H-5996-014314290) 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 amplifiers are critical components for military applications, and the government intends to solicit and negotiate with only one source under FAR 6.302-1. Interested parties must submit their capability statements within 45 days of the notice, and all inquiries should be directed to Sarah Ream at (717) 605-6457 or via email at SARAH.E.REAM.CIV@US.NAVY.MIL.
