The Department of Defense, through the NAVSUP Weapon Systems Support office, is planning to solicit a sole source contract for the acquisition of a specific gearbox (NSN: 1615 013838992, P/N: 70351-08080-045) essential for the H60 platform, with Sikorsky identified as the Original Equipment Manufacturer (OEM). This procurement is critical as Sikorsky is the only supplier capable of providing the necessary repair services due to the lack of available drawings or data for alternative procurement options. The solicitation is expected to be posted electronically on NECO by April 17, 2024, with an award anticipated by June 30, 2025; interested parties may submit capability statements to Samantha M. Freedman at SAMANTHA.M.FREEDMAN.CIV@US.NAVY.MIL, although the contract will not be delayed for Source Approval Requests. This acquisition falls under NAICS code 336413 and is not set aside for small businesses.
