The Department of Defense, specifically the Department of the Air Force, is conducting a Sources Sought notice to identify potential sources for the B-1 Retaining Ring, National Stock Number (NSN): 5325-01-654-3362. The objective is to gather market research information to determine if other responsible sources exist, as the government intends to issue a Firm-Fixed-Price sole source solicitation to Meggitt Aircraft Braking System, the sole owner of the necessary data. The B-1 Retaining Ring is crucial for landing gear systems, which include various components such as wheels, brakes, and antiskid systems. Interested parties, particularly small businesses including 8(a), Service-Disabled Veteran-Owned, Hubzone, and Women-Owned concerns, are encouraged to respond with their business status and relevant experience by contacting Jayson Skow at jayson.skow@us.af.mil or Christina Witt at christina.witt.2@us.af.mil.
