Notes: The B-29 was designed by Boeing as a sucessor to the B-17 Flying Fortess. The long range bomber was introduced to the Air Force in 1940, but production was delayed to incorporate changes in armament and load.

The first World War II B-29 raid was from specially designed bases in China on Japanese shipyards in Bangkok, Thailand in June 1944. The B-29's were the first aircraft to bomb mainland Japan since Doolittle's raid in 1942 in the B-25 Mitchell. The B-29 was not used in the European Theater of Operations due to the short flying distances. The B-29 was the only US produced bomber flown by a foreign country (Great Britian) in post World War II.

The B-29 is the only aircraft ever to have used Nuclear Bombs in actual combat. The most destructive raid of World War II occurred when 334 B-29's bombed Tokyo on 9-10 March 1945, 1.5 million people were left homeless and over 83,000 killed versus the 80,000 killed in Hiroshima and Nagasaki combined.
