US Air Force sees early 2030s rollout for revamped Sentinel nuclear missile

The U.S. Air Force is anticipating the rollout of the revamped Sentinel nuclear missile, officially known as the LGM-35A intercontinental ballistic missile (ICBM), in the early 2030s. This development follows a recent Nunn-McCurdy review, during which the program's Milestone B status was revoked. The Air Force is expected to make a new decision regarding the program by the end of 2026. Air Force Gen. Dale White emphasized that the program's standards remain high, stating, “We certainly have not lowered the bar, and we certainly have not taken on any risk by doing this.” This assertion indicates the Air Force's commitment to maintaining rigorous criteria for the Sentinel ICBM's development and operational readiness. The Sentinel ICBM program is seen as a critical component of the U.S. nuclear deterrent strategy. The timeline for its operational status is significant, as it reflects the Air Force's ongoing efforts to modernize its nuclear capabilities in response to evolving global security challenges. The early 2030s rollout is part of a broader initiative to ensure that the U.S. maintains a credible and effective nuclear deterrent. Overall, the Sentinel ICBM program is poised to advance through key milestones in the coming years, with the Air Force aiming to address any challenges identified during the review process and to ensure the program's successful implementation.
