The Department of Defense, specifically the Department of the Air Force, is seeking sources for alternative high-security locks through a Request for Information (RFI) issued by the Hanscom Force Protection International Programs. The RFI aims to identify solutions that comply with the detailed specifications outlined in the attached document, MIL-DTL-43607J, which includes requirements for durability, security, and compliance with export control and ITAR regulations for Foreign Military Sales (FMS). The high-security locks are critical for military applications, necessitating features such as tamper resistance, environmental durability, and unique key configurations with a minimum of 100,000 different key changes per contract. Interested parties can reach out to Christopher Bothwell at christopher.bothwell.1@us.af.mil or Taylor Bentley at taylor.bentley.2@us.af.mil for further information, noting that there is no proposed contracting action at this time.
