USAF Plans To Expand Nuclear Bomber Bases
FAS November 17
By Hans M. Kristensen
The US Air Force is working to expand the number of strategic bomber bases that can store nuclear weapons from two today to five by the 2030s.
The plan will also significantly expand the number of bomber bases that store nuclear cruise missiles from one base today to all five bombers bases by the 2030s.
The expansion is the result of a decision to replace the non-nuclear B-1B bombers at Ellsworth AFB and Dyess AFB with the nuclear B-21 over the next decade-and-a-half and to reinstate nuclear weapons storage capability at Barksdale AFB as well.
The expansion is not expected to increase the total number of nuclear weapons assigned to the bomber force, but to broaden the infrastructure to accommodate mission growth, Air Force Global Strike Command Commander General Timothy Ray told Congress last year.

Pretty good discussion of base storage changes and expansion of bomber force anticipated with detailed charts, nuclear arms limitations implications, etc.
