"Current plan is to remove all 400 Minuteman III ICBMs made by Boeing from silos by 2039."

(Bloomberg) -- 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 US Air Force has unveiled plans to keep its 1970s-era intercontinental ballistic missiles in service for 11 more years, until 2050. The previous strategy included keeping the Boeing-made 400 Minuteman III ICBMs in silos until 2039 and gradually replace them with new Sentinel models.

However, the Sentinel has been plagued with delays and increasing costs, forcing policymakers to rely on the 1970s-era missiles for a decade longer than originally planned. After all, the transition from Minuteman III to Sentinel must take place smoothly without compromising the nation’s nuclear guard.

Notably, Sentinel would be a key component of the USA’s nuclear triad, covering the land-based portion.

In a statement to Bloomberg, the US Air Force said it was continuing to develop a new acquisition strategy.
