The Department of Defense, specifically the U.S. Air Force, is conducting a Request for Information (RFI) to identify potential sources for the repair of the F-16 Hydraulic Drive Unit (HyDrive), particularly the M61A1 20mm HyDrive, with an NSN of 1005-01-061-8335. The procurement aims to establish a five-year contract for repair services, including a basic year and four option years, with projected quantities ranging from 1 to 30 units in the initial year and 1 to 20 units in subsequent years. The HyDrive is critical for the operation of the F-16 aircraft's weapon system, requiring strict quality control due to its operation under extreme conditions, including high vibrations and temperature variations. Interested parties must submit documentation showcasing their capabilities and experience by November 4, 2024, and can contact Melissa Wells or Charles Harris for further information.
