Although the first specifications for the B-29 were made in 1940, the first B-29 (Renton, WA-built) was not delivered until 1943. And, the Superfortress did not reach full service until 1944.
The B-29 was the most technologically advanced aircraft in the US fleet. The United States government had asked Boeing to produce a long range, accurate bomber that could travel the long distances to Japan. Originally produced for the long-term bombing campaign planned for Japan, the B-29 was instead used to deliver the atomic bomb onboard the Enola Gay and Boxcar to Hiroshima and Nagasaki. This proved to be a much quicker way of ending the war, but it cost millions of Japanese lives. Later models of the B-29 were developed for use in weather programs and geological surveys, and was given the designation F-13. The F-13 was responsible, from bases 1500 miles away, for all the reconnaissance work which preceded the bombing of Japan. These models were in use until the early 60s.
