The B61 Life-Extension Program: Increasing NATO Nuclear Capability and Precision Low-Yield Strikes
A modified U.S. nuclear bomb currently under design will have improved military capabilities compared with older weapons and increase the targeting capability of NATO’s nuclear arsenal. The B61-12, the product of a planned 30-year life extension and consolidation of four existing versions of the B61 into one, will be equipped with a new guidance system to increase its accuracy. As a result, the U.S. non-strategic nuclear bombs currently deployed in five European countries will return to Europe as a life-extended version in 2018 with an enhanced capability targets.
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.
