Description

The Boeing B-17 Flying Fortress is a four-engine heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry outperformed both competitors and exceeded the Air Corps' expectations. Although Boeing lost the contract because the prototype crashed, the Air Corps was so impressed with Boeing's design that they ordered 13 more B-17s for further evaluation. From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances.Two variants: the B17E & B17F were primarily employed by the United States Army Air Forces (USAAF) in the Daylight Precision strategic bombing campaign of World War II, against German industrial and military targets, in 1942. The United States Eighth Air Force, based at various airbases in the Southern counties of England, and the Fifteenth Air Force, based in Italy, complemented the RAF Bomber Command's night-time bombing campaign in the Combined Bomber Offensive to help secure air superiority over the cities, factories and battlefields of Western Europe in preparation for the invasion of France in 1944. The B-17 also participated to a lesser extent in the War in the Pacific, early in World War II, where it conducted raids against Japanese shipping and airfields. The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by Boeing that was flown primarily by the United States toward the end of World War II and during the Korean War. It was one of the largest aircraft to have seen service during World War II and a very advanced bomber for its time, with features such as a pressurized cabin, an electronic fire-control system, and a quartet of remote-controlled machine-gun turrets operated by the fire-control system in addition to its defensive tail gun installation. The name "Superfortress" was derived from that of its well-known predecessor, the B-17 Flying Fortress. Although designed as a high-altitude strategic bomber, and initially used in this role against the Empire of Japan, these attacks proved to be disappointing; as a result the B-29 became the primary aircraft used in the American firebombing campaign, and was used extensively in low-altitude night-time incendiary bombing missions. One of the B-29's final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and Nagasaki.
