CHEYENNE, Wyo. (AP) — U.S. Sens. Mike Enzi and John Barrasso have joined a bipartisan coalition of senators in expressing concerns over proposed cuts in the U.S. nuclear forces.

The two Wyoming Republicans joined other senators in sending a letter with their concerns to the chairman and ranking member of the Strategic Forces Subcommittee.

The letter states support for the U.S. intercontinental ballistic missile force.

The United States currently has 450 Minuteman III missiles with 150 missiles each at three air bases, including F.E. Warren Air Force Base at Cheyenne.

The letter asks that any reductions be made equally among the three facilities and that reductions be done incrementally.

The Obama administration is considering new cuts to the U.S. nuclear force.
