The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking proposals for the procurement of four hydraulic motor-pumps, identified by NSN 7R-1650-012246682-VH and part number 70550-02046-106. This procurement is critical for maintaining aircraft hydraulic systems, which are essential for the operational readiness of naval aviation. The government intends to solicit and negotiate with only one responsible source due to the lack of available drawings and data, and interested parties must submit their capability statements by email to Julianna Macrillo at julianna.m.macrillo.civ@us.navy.mil within 45 days of this notice, with an anticipated award date set for August 2024.
