The Convair B-36 Peacemaker was a strategic bomber that was built by Convair and operated by the United States Air Force (USAF) from 1949 to 1959. The B-36 is the largest mass-produced piston-engined aircraft ever built. It has the longest wingspan of any combat aircraft ever built, at 230 ft (70 m). The B-36 was the first bomber capable of delivering any of the nuclear weapons in the U.S. arsenal from an internal bomb bay without aircraft modifications. With a range of 10,000 mi (16,000 km) and a maximum payload of 87,200 lb (39,600 kg), the B-36 is capable of intercontinental flight without refueling. Entering service in 1948, the B-36 was the primary nuclear weapons delivery vehicle of Strategic Air Command (SAC) until it was replaced by the jet-powered Boeing B-52 Stratofortress beginning in 1955. All but four aircraft have been scrapped. (Wikipedia)

On 18 March 1953, RB-36H-25, 51-13721, flew off course in bad weather and crashed near Burgoyne's Cove, Newfoundland, Canada (48.184352°N 53.664271°W). Brigadier General Richard Ellsworth was among the 23 airmen killed in the crash.    

B-36s were involved in two "Broken Arrow" incidents. On 13 February 1950, B-36 (Serial No. 44-92075), crashed in an unpopulated region of British Columbia, resulting in the first loss of an American atom bomb. The bomb's plutonium core was dummy lead, but it did have TNT, and it detonated over the ocean before the crew bailed out. Locating the crash site took some effort. On 4 November 2016, however, an object similar to the bomb was reported to have been located by a diver near the archipelago of Haida Gwaii, 80 km (50 mi) off the coast of British Columbia; the Royal Canadian Navy said vessels would be deployed to investigate the object. After investigation, the Royal Canadian Navy determined that it was not the lost bomb. Later in 1954, the airframe, stripped of sensitive material, was substantially destroyed in situ by a U.S. military recovery team. (Wikipedia)

The B-36 made its maiden flight in August 1946, and in June 1948 the Strategic Air Command received its first operational B-36.  Some B-36s served as photographic reconnaissance aircraft, and others were adapted to launch and retrieve specially modified RF-84F/K reconnaissance planes.  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.  It carried 86,000 pounds of nuclear or conventional bombs.  When production ended in August 1954, more than 380 B-36s had been built for the USAF.  In 1958-1959, the USAF replaced the B-36 with the all-jet B-52.  Although never used in combat, the B-36 was a major deterrent to enemy aggression.  Making the last B-36 flight ever, the aircraft on display flew to the NMUSAF from Davis-Monthan Air Force Base, Arizona, on 30 April 1959.
