The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two pump units (NSN 7H-4320-016897526) for repair or modification. The procurement is limited to one source due to the Government's lack of ownership of the necessary data and the determination that it is uneconomical to reverse engineer the part. These pump units are critical components within military operations, and the Government intends to solicit and negotiate under FAR 6.302-1, with a 45-day window for interested parties to express their capabilities. For further inquiries, interested vendors can contact Lamar R. Crummel at (717) 605-6474 or via email at lamar.crummel@navy.mil.
