The Department of Defense, specifically the Department of the Navy, is seeking to procure four units of a radio frequency amplifier under a presolicitation notice. The procurement involves the repair and modification of the amplifier, identified by NSN 7H-5996-016819587, and is designated as an 8(a) Sole Source opportunity, indicating that it will be negotiated with only one source due to the government's determination that it is uneconomical to acquire the necessary data or rights for competitive procurement. This amplifier is crucial for military applications, and the contract will be awarded only to a qualified source that meets the required specifications. Interested parties should contact Russell W. Kreider at (717) 605-3918 or via email at RUSSELL.W.KREIDER.CIV@US.NAVY.MIL for further details, with proposals due within 45 days of the notice publication.
