Saving Billions on the US Nuclear Deterrent
Summary
The United States Air Force has initiated a program to replace its current arsenal of intercontinental ballistic missiles (ICBMs) with an entirely new missile force known as the Ground-Based Strategic Deterrent (GBSD). The GBSD’s price tag continues to grow beyond initial expectations, with the program on track to become one of the country’s most expensive nuclear-related budgetary items over the next decade.
The GBSD is risky, draws funding away from more urgent priorities, and will exacerbate the Pentagon’s budget crisis. A better approach would be to extend the life of the current ICBM force (the Minuteman III) in the near term, while spreading the costs of nuclear modernization out over the longer term. This approach will ensure that the United States can field a capable ICBM force on a continuous basis without compromising other critical security priorities.
The SIPRI chapter describes the nuclear weapon modernization programs underway in each nuclear-armed state and provides estimates for how many nuclear warheads each country possesses.
FAS researchers Hans Kristensen and Matt Korda with the Nuclear Information Project write in the new SIPRI Yearbook 2024, released today.
The total number of U.S. nuclear warheads are now estimated to include 1,770 deployed warheads, 1,938 reserved for operational forces. An additional 1,336 retired warheads are awaiting dismantlement, for a total inventory of 5,044 warheads.
A military depot in central Belarus has recently been upgraded with additional security perimeters and an access point that indicate it could be intended for housing Russian nuclear warheads for Belarus’ Russia-supplied Iskander missile launchers.
