northropyb49

The Northrop YB-49 was a prototype jet-powered heavy bomber aircraft developed by Northrop Corporation shortly after World War II for service with the U.S. Air Force. The YB-49 featured a flying wing design and was a jet-powered development of the earlier, piston-engined Northrop XB-35 and YB-35. The two YB-49s actually built were both converted YB-35 test aircraft The YB-49 never entered production, being passed over in favor of the more conventional Convair B-36 piston-driven design. Design work performed in the development of the YB-35 and YB-49 nonetheless proved to be valuable to Northrop decades later in the eventual development of the B-2 stealth bomber, which entered service in the early 1990s So there was never a B-49.

This was the tenth Northrop YB-35 (s/n 42-102376) converted to be a testbed for a proposed photo-recon version of the B-49 (re-designated as the lone YRB-49A prototype -- company designation Model NS-41). It was powered by six Allison J35-A-19 jet engines (upgraded from the J35-A-5s in the earlier prototypes): four internally and two in pods under the wings. Performance was unimpressive compared to the YB-47, and the a/c was scrapped in Nov. 1953.
