Inside the effort to replace America’s Minuteman III nuclear missiles

In Cheyenne, Wyoming, CBS News joined U.S. Strategic Command and Air Force Global Strike Command leaders for an exclusive look at the modernization of America’s nuclear arsenal. The visit focused on the transition from the aging Minuteman III Intercontinental Ballistic Missiles (ICBMs) to the new Sentinel system. Despite being a decade behind schedule, the upgrade is crucial for maintaining national security. At F.E. Warren Air Force Base, home to 150 Minuteman III ICBMs, Col. Terrance J. Holmes emphasized the importance of readiness and nuclear deterrence, even during the transition. The Minuteman III system, operational since 1961, is well past its intended lifespan, highlighting the need for modernization. The visit underscored the ongoing efforts to ensure the U.S. remains prepared to respond to threats, with approximately 400 ICBMs ready at any moment.
