At that time, the 22 B-29s of the 19th Bombardment Group stationed at Andersen Field on Guam were the only aircraft capable of hitting the Korean peninsula, and this unit was ordered to move to Kadena air base on Okinawa and begin attacks on North Korea. These raids began on 28 June. On 29 June, clearance was given for B-29 attacks on airfields in North Korea. The B-29s were frequently diverted into tactical attacks against advancing North Korean troops. On 8 July, a special FEAF Bomber Command was set up under the command of Major General Emmett O'Donnell. On 13 July, the FEAF Bomber Command took over command of the 19th Bombardment Group and of the 22nd and 92nd Bombardment Groups which had been transferred from SAC bases in the United States.

Modern era Twentieth Air Force was reactivated on 1 September 1991 as a component of Strategic Air Command and located at Vandenberg AFB, California. Its mission was the responsibility for all land-based Intercontinental Ballistic Missiles (ICBM)s. 20th Air Force's rebirth came at a time when America's nuclear forces were entering a decade of unprecedented force reductions and changes. Spawned by the Cold War's end and the breakup of the Soviet Union, these changes reshaped the basic fabric of the nation's nuclear deterrent forces. In the decades since its reactivation, 20th Air Force has experienced four
