The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three units of a power supply under the presolicitation notice titled "61--POWER SUPPLY, IN REPAIR/MODIFICATION OF." The procurement involves the National Stock Number (NSN) 7H-6130-015849057, with delivery required to two locations: DLA Distribution in New Cumberland, PA, and DLA Distribution San Joaquin in Tracy, CA. This power supply is critical for military operations, and the government has determined that it is uneconomical to reverse engineer or purchase the data rights for this part. Interested parties are encouraged to express their interest and capabilities, as the government intends to negotiate with only one source under FAR 6.302-1. For further inquiries, potential bidders can contact Dianne Wydra at (215) 697-6681 or via email at Dianne.L.Wydra.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication.
