The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure a valve assembly for repair or modification. The requirement involves a specific National Stock Number (NSN 7H-4820-014216395) with a quantity of one unit, and the delivery will be on a Free on Board (FOB) origin basis. This valve assembly is critical for maintaining operational capabilities, 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 solicitation under FAR 6.302-1. Interested parties are encouraged to express their interest and capability within 45 days of this notice, with the primary contact being Madison Gray at (717) 605-4056 or via email at MADISON.M.GRAY4.CIV@US.NAVY.MIL.
