The B-29A was an improved version of the original B-29 production model. All 1,119 B-29A's were built exclusively at the Boeing plant in Renton, Washington, formerly used by the United States Navy.
Enhancements made in the B-29A included a better wing design and defensive modifications. Due to a demonstrated weakness to head-on fighter attacks, the number of machine guns in the forward dorsal turrets was doubled to four. Where the wings of previous models had been made by the sub-assembly of two sections, the B-29A began the trend of using three. This made construction easier, and increased the strength of the airframe. The B-29A was produced until May 1946, when the last aircraft was completed. It was much used during the Korean War, but was quickly phased out when the jet bomber became operational.
Washington B Mk 1 - This was the service name given to 88 B-29As supplied to the Royal Air Force.
