Changes

In 1946, the [[Strategic Air Command]] acquired many of the B-29s still in service. However, these planes were largely antiquated and had seen heavy use during the war. Boeing responded to SAC's need, first with the B-29D, a much-improved model that the new [[United States Air Force|Air Force]] redesignated as the B-50. This aircraft had 59 percent more power than the original B-29, along with better aerodynamic surfaces, larger flaps, faster-retracting landing gear, and improved hydraulic control systems. It also sported a higher tail that could fold during storage, and a stronger, lighter wing. It also had twelve guns (the original B-29 had ten) and required a crew of twelve. In all, Boeing built 371 B-50s, including 79 B-50As.<ref name=boeing2>Authors unknown. "[http://www.boeing.com/history/boeing/b50.html B-50 Bomber]."

B-29 and B-50 squadrons saw intensive action during the [[Korean War]], this time against jet fighter/interceptors using electronic weaponry.<ref name=Boeing1/> Losses were correspondingly much heavier. The last B-50s (actually KB-50D tankers) were retired from active service in 1965.<ref name=boeing2/><ref name=Baugher/>
