The Boeing B-29 Superfortress was the most advanced and successful of all World War II bombers. Conceived in the late 1930s as a high-speed, high-altitude, long-range "super bomber", the first prototype B-29 did not fly until September 1942. It entered the war in time to make a significant impact, including the dropping of the two atomic bombs that led to the surrender of Japan and the end of the war. This is the complete history of this extraordinarily advanced aircraft, and includes full details of its design and manufacture and service with American and British air forces during World War II, the Korean War and after.
