Convair B-36 Peacemaker

The Convair B-36 (nicknamed Peacemaker) was a strategic bomber built by Convair and operated solely by the United States Air Force (USAF). The B-36 was the largest mass-produced piston engined aircraft ever made and had the largest wingspan in a combat aircraft ever built (230 ft (70 m)), although there have been larger military transports. The B-36 was the first bomber capable of delivering thermonuclear weapons from within a fully-enclosed bomb-bay. With a range of over 6,000 miles (9,700 km) and a maximum payload of at least 72,000 lb (33,000 kg), the B-36 was the first operational bomber with an intercontinental range, setting the standard for subsequent USAF long range bombers, such as the B-52 Stratofortress, B-1 Lancer, and B-2 Spirit.
