Col. Steven Kravitsky is the new commander of the 90th Missile Wing at F.E. Warren Air Force Base in Cheyenne.

Kravitsky most recently served as the Assistant Deputy Director for Homeland Defense and Current Operations on the Joint Staff at the Pentagon in Washington D.C.

He previously had served as the commander of the 12th Missile Squadron at Malmstrom Air Force Base in Montana.

Kravitsky replaces Col. Tracey Hayes as leader of the 90th MIssile Wing. Hayes led the 90th for about two years and was the first female officer to hold that post. The 90th Missile Wing oversees the base's 150 Minuteman III intercontinental ballistic missiles.

Kravitsky formally assumed command on Wednesday.
