Air Force Weighs Keeping 1970s-Era Missiles Until 2050
The US Air Force is considering contingency plans that would extend the life of 1970s-era intercontinental ballistic missiles by 11 more years to 2050 if delays continue to plague the new Sentinel models intended to replace them. The current plan is to remove all 400 Minuteman III ICBMs made by Boeing Co. from silos by 2039… The Sentinel was projected last year to be deployed starting in May 2029. The first test flight was once projected for December 2023, but fiscal 2025 budget documents indicated a slip to February 2026.
The estimated cost of the new Sentinel intercontinental ballistic missiles (ICBM), originally at ~$110 billion, is now north of $180 billion. And this is before recognition of the immensity of supplying new command and control communications and recent consideration that its hardened silos may have to be replaced. IMHO it’s a propitious time to argue again for eliminating the land-based ICBM leg of the Triad. After all, one of its stated purposes is to act as a “nuclear sponge” for incoming Russian warheads. The odds of that are not zero and may increase if ICBMs are uploaded with multiple warheads after the New Strategic Arms Reduction Treaty expires in February 2026. More temptation for a preemptive first strike.
