The Boeing B-29 Superfortress, a versatile and successful aircraft, led to the development of twenty-seven unique versions. These versions added new features to the basic model, proving the adaptability of the B-29 design.
This production continued beyond World War Two into the post-war years, with Boeing proposing even more B-29 variants.
Some of these proposals didn’t reach production, but many did. Five of these versions – F-13, KB-29M, KB-29P, SB-29, and WB-29 – were manufactured in large numbers.
Notable among these were the KB-29M and KB-29P aerial refueling tankers, which served until they were replaced by the Boeing KC-97 in the mid-1950s. Another significant model was the B-29MR, which functioned as both a receiver and a tanker.
The most substantial development, however, was the proposed B-29D, which later became the B-50. This version marked a major progression of the original B-29 design.
All in all, the production of these different versions culminated in a grand total of 3,970 B-29 aircraft. This number showcases the lasting success of the B-29 Superfortress in aviation history.
