The U.S. Air Force is pushing ahead with its struggling Sentinel intercontinental ballistic missile (ICBM) program despite a new projected price tag of nearly $141 billion, close to twice the original estimate, and now years of expected delays. The Pentagon says it has assessed that there are no lower-cost, but similarly capable alternatives to Sentinel, which is expected to replace the existing Minuteman III ICBM as one of the three legs of America’s nuclear deterrent triad.
The Office of the Secretary of Defense announced the results of an official review of the Sentinel program today. By law, per what is commonly referred to as the Nunn-McCurdy Amendment, defense programs that see certain levels of extreme cost growth must be canceled unless various criteria are met. Sentinel’s rising price point triggered a breach of the Nunn-McCurdy statute in January. The Air Force also sacked the top officer in charge of the program last month, but said this was “not directly related to the Nunn-McCurdy review,” according to Defense One.
The Air Force currently has some 400 LGM-30G Minuteman IIIs deployed in silos spread across five states.
