Congress has provided $168 million more than the Trump administration’s budget request over the past two years to keep the development of the Air Force’s new intercontinental ballistic missile (ICBM) system ahead of schedule. Lawmakers approved the transfer earlier this year of $100 million in unspent fiscal year 2018 Pentagon funds to the program known as the Ground-Based Strategic Deterrent (GBSD). In addition, the final fiscal year 2019 defense appropriations bill provided $69 million above the initial request of $345 million for the program. (See ACT, November 2018.)

The GBSD program is slated to replace the current force of 400 deployed Minuteman III missiles and their supporting infrastructure and remain in service through the 2070s. The Air Force in August 2017 selected Boeing Co. and Northrop Grumman Systems Corp. to proceed with the development program. (See ACT, October 2017.) There is significant uncertainty about the projected acquisition cost of the new missile system, raising questions about affordability. An independent Pentagon cost estimate conducted in 2016 put the GBSD program’s price tag at between $85 billion and $150 billion, including the effects of inflation, well above the Air Force’s initial estimate of $62 billion. Pentagon officials ultimately approved the $85 billion figure as the initial official cost of the program. (See ACT, March 2017.) The Air Force had planned to produce an updated cost estimate by the end of 2018. The Pentagon did not respond to a request for comment on whether the service has done so.—KINGSTON REIF
