The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 17 rotary pumps under a presolicitation notice. The procurement involves the repair and modification of a specific National Stock Number (NSN 7H-4320-014529381), and the government has determined that it is uneconomical to purchase the data or rights necessary to contract this repair from additional sources. These pumps are critical components in various military applications, and the government intends to solicit and negotiate with only one source for this requirement, as outlined under FAR 6.302-1. Interested parties are encouraged to express their interest and capability to fulfill this requirement within 45 days of the notice, and they may contact Alexandra R. Durham at (717) 605-6457 or via email at alexandra.r.durham.civ@us.navy.mil for further information.
