Convair B-36 Peacemaker
Rear view of an engine on the port wing of a Convair B-36 Peacemaker bomber aircraft undergoing maintenance. Powered by six Pratt & Whitney R-4360 engines, the B-36J cruised at 230 mph, but for additional bursts of speed its four General Electric J47s increased the maximum speed to 435 mph. Responding to the U.S. Army Air Forces' requirement for a strategic bomber with intercontinental range, Consolidated Vultee (later Convair) designed the B-36 during World War II.
