Convair B-46




By December 1944 proposals had been received from Boeing, Convair, Martin and North American for medium axial turbojet-powered bomber for tactical- and operational-level use. Convair gained a contract for three XB-46 prototypes from the US Army Air Force.
Of all-metal construction, the XB-46 was of high-wing cantilever monoplane configuration, had a slim oval-section fuselage, conventional tail unit, retractable tricycle landing gear and was designed to accommodate a crew of three. Power was provided by four General Electric TG‑180 turbojet engines, these being mounted in pairs.
First flown on 2 April 1947, the XB-46 was handed over to the newly-formed US Air Force in late 1947, attaining an average speed of 858km/h during its delivery flight to Wright Field at Daytona, Ohio. Despite this performance the XB-46 remained a one-off prototype, cancelled in 1947, the USAF ordering the Boeing B-47 Stratojet into production.
