The U.S. Air Force revoked Milestone B for the LGM-35A 'Sentinel' ICBM after a Nunn-McCurdy review and is executing a formal restructure with a rebaseline decision due by end-2026. The program, projected at about $141 billion, now targets an initial capability in the early 2030s and a missile-pad test next year.
