The Department of Defense, specifically the Department of the Navy, is seeking to procure ten hydraulic pumping units under a presolicitation notice. The procurement involves the repair and modification of a specific National Stock Number (NSN 7H-4320-014843565) and is intended to be negotiated with a single source due to the unavailability of data rights for competitive procurement. These pumping units are critical components in various military applications, and the government has determined that it is uneconomical to reverse engineer or purchase the necessary data from additional sources. Interested parties should contact Rachael Costanzo at (717) 605-2462 or via email at Rachael.L.Costanzo.CIV@us.navy.mil for further details, and they must include their CAGE code in any solicitation requests. The proposed contract action includes a 100% option exercisable within 179 days of the order date.
