The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanics, is seeking to procure 26 units of a rotary pump, identified by NSN 7H-4320-013124098, for repair or modification. The procurement is characterized by the government's determination that it is uneconomical to purchase the data or rights necessary for contracting repair from additional sources, thus limiting competition to a single source under FAR 6.302-1. This rotary pump is critical for military operations, and interested parties are encouraged to express their capabilities to meet this requirement within 45 days of the notice. For further inquiries, potential vendors can contact Alexander Craft at (717) 605-4147 or via email at ALEXANDER.CRAFT@NAVY.MIL.
