The Convair B-36 "Peacemaker" was a strategic bomber built by Convair and operated solely 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 had the longest wingspan of any combat aircraft ever built, at 230 ft (70.1 m). The B-36 was the first bomber capable of delivering any of the nuclear weapons in the U.S. arsenal from inside its four bomb bays 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 was capable of intercontinental flight without refuelling.

Entering service in 1948, the B-36 was the primary nuclear weapons delivery vehicle of the Strategic Air Command (SAC) until it was replaced by the jet-powered Boeing B-52 Stratofortress from 1955. All but five examples were scrapped.

The B-36 set the standard for range and payload for subsequent U.S. intercontinental bombers.

The genesis of the B-36 can be traced to early 1941, prior to the entry of the United States into World War II. At the time it appeared there was a very real chance that Britain might fall to the Nazi "Blitz", making a strategic bombing effort by the United States Army Air Corps (USAAC) against Germany impossible with the aircraft of the time. The United States would need a new class of bomber which would reach Europe and return to bases in North America, necessitating a combat range of at least 5,700 miles (9,200 km), the length of a Gander, NewfoundlandBerlin round trip. The USAAC therefore sought a bomber of truly intercontinental range, similar to the German RLM's ultra-long-range Amerika Bomber program, which itself as a 33-page proposal was submitted to Reichsmarschall Hermann Goering on May 12, 1942 at the RLM.
