USAF to finish Sentinel (LGM-35A) restructure by 2026 after Milestone B revocation; IOC pushed to early 2030s
The U.S. Air Force restructured the LGM‑35A "Sentinel" ICBM after a Nunn‑McCurdy review revoked Milestone B amid soaring costs (about $141 billion) and schedule slip. The service aims to complete the restructure and reach Milestone B by end‑2026, with a missile‑pad test next year and IOC in the early 2030s.
