During World War II, the United States used a variety of bomber planes for air combat, tactical bombing raids and ground support. These bombers included the Boeing B-17 Flying Fortress, the Boeing B-29 Superfortress and the Douglas A-26 Invader. Additional bombers included the Boeing B-25 Mitchell, which made bombing runs on Tokyo at the command of James Doolittle, and the TBF Avenger, the most successful torpedo bomber used by the Americans during the war.
The B-17 Flying Fortress made bombing runs in both the Pacific and European theaters. It made its name performing daylight, long-range bombing runs with the purpose of taking out military targets such as industrial buildings. It used a Norden bombsight to help hit targets accurately from its altitudes and presented the ability to withstand battle damage.
The military used the B-29 Superfortress predominately in the Pacific theater, where it was the aircraft that dropped atomic bombs on Hiroshima and Nagasaki.
One of the popular light bomber aircraft, the A-26 Invader completed 11,567 missions and only lost 67 aircraft in Europe over the course of World War II. The bomber dropped 18,054 tons of bombs in Europe, although the military used the bomber in both the Pacific and Europe theaters.
