The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure hydraulic cylinders specifically for CH53 helicopters on a sole source basis from Sikorsky (CAGE: 78286). The procurement involves the acquisition of NSN 7R-1630-017215990-H5, P/N: X0625-00002-102, with a quantity of 5 units, and delivery will be on a FOB origin basis. This hydraulic cylinder is critical for the operation of aircraft wheel and brake systems, and Sikorsky is the only known source capable of providing the necessary repair support, as the government does not possess the data or rights to procure from alternative suppliers. Interested parties must submit their capability statements to Megan N. McGinley at megan.n.mcginley.civ@us.navy.mil by January 23, 2025, with the anticipated award date set for January 30, 2025.
