History.
Activated in 1943 as the 42nd Bombardment Wing and controlled Martin B-26 Marauder groups as part of Twelfth Air Force. "The wing first saw combat in the invasion of Italy, where its units flew close support missions to stop the German counterattack on the beachhead at Salerno during September 1943. As the Allied forces progressed, the 42nd took a leading part in interdicting Axis road and rail transport, and later in 1944, in the attacks against the monastery at Cassino. In August 1944, it supported the Allied landings in southern France. As the war drew to a close the 42nd attacked German positions along the Siegfried Line and, in support of the Allied forces in their sweep across southern Germany, bombed enemy strong points, and communications and supply facilities."
The French Bretagne Bombardment Group was attached in 1943. 
Reactivated an intermediate command echelon of Strategic Air Command in March 1951, the 42nd Air Division "equipped and trained its assigned units to conduct strategic air warfare using nuclear or conventional weapons anywhere in the world. It also trained and maintained air refueling assets. Tankers from units assigned to the 42nd supported the Eielson Tanker Task Force and, over the years, occasionally deployed to Spain for Spanish Area Support. The division conducted numerous staff assistance visits and simulated no notice inspections, and participated in exercises such as Buy None and Global Shield."
Aircraft and personnel from units assigned to the division, at various times in the late 1960s and early 1970s, deployed to Southeast Asia and took part in Operation Arc Light and Operation Young Tiger missions. Subordinate units of the 42nd deployed aircraft and personnel in support of the Vietnam War.
The division was inactivated in 1991 as part of the post-Cold War reduction of USAF forces.
