Defense Secretary Ash Carter says the Pentagon is committed to correcting what he calls decades of shortchanging its nuclear forces.

Carter spoke Monday at a nuclear missile and bomber base in Minot, North Dakota. He says $108 billion is earmarked for sustaining and improving the forces over the next five years.

Carter was taken 85 feet underground to a Minuteman 3 missile launch control center, and visited B-52 bomber crews and facilities.

Carter thanked the nuclear work force and expressed support for building a new generation of nuclear-armed missiles, bombers and submarines — a plan expected to cost hundreds of billions of dollars.
