The Northrop YB-49 was a prototype jet-powered heavy bomber aircraft developed by Northrop shortly after World War II. Intended for service with the U.S. Air Force the XB-49 would feature a flying wing design. It was a jet-powered development of the 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 Peacemaker piston-driven design.
Made by Northrop Corporation.
