Mighty Ninety Airmen recently completed an extended effort to shift the annual nuclear code change operation from a manual endeavor to a remote process with the new ICBM Cryptographic Upgrade (ICU II) program.

The 90th Missile Wing was the first of Twentieth Air Force’s three missile bases to complete ICU II, giving time back to Airmen to focus on their normal duties of maintaining and sustaining the Minuteman III weapon system.
