The Department of Defense, specifically the Department of the Navy, is seeking to procure 18 units of the BPAU assembly for repair and modification, as outlined in the presolicitation notice. The procurement involves a specific National Stock Number (NSN 7H-6130-016432530) and is classified under the PSC code 6130, which pertains to electrical converters that are non-rotating. This contract action is significant as it addresses a critical supply need for the Navy, and the government has determined that it is uneconomical to acquire the data or rights necessary for competitive procurement, thus opting for a sole-source negotiation. Interested parties are encouraged to express their interest and capabilities to the primary contact, Valentino P. Arena, via email at VALENTINO.P.ARENA.CIV@US.NAVY.MIL, within 45 days of the notice publication, as the government will consider all proposals received during this timeframe.
