The B-29 Superfortress is a four-engine heavy bomber aircraft developed by Boeing in the late 1930s and early 1940s.
It was primarily used by the United States Army Air Forces during World War II and the Korean War and was the first aircraft with the capability of flying at altitudes of up to 31,850 feet. It had a range of 3,250 miles and was equipped with state-of-the-art technology such as radar and pressurized cabins.
The B-29 was used in a number of notable missions, including the dropping of atomic bombs on Hiroshima and Nagasaki in 1945, which helped bring about the end of World War II.
After the war, many B-29s were scrapped or converted for other uses, but a small number have been preserved as museum exhibits.
