The Convair B-36 ยซPeacemakerยป is a strategic bomber built by Convair and operated by the United States Air Force 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 70 m.
Entering service in 1948, the B-36 was the primary nuclear weapons delivery vehicle of Strategic Air Command until it was replaced by the jet-powered Boeing B-52 Stratofortress beginning in 1955.
The B-36 took shape as an aircraft of immense proportions. It was two-thirds longer than the previous ยซsuperbomberยป, the B-29. The wingspan and tail height of the B-36 exceeded those of the 1960s Soviet Union's Antonov An-22 Antheus military transport, the largest ever propeller-driven aircraft put into production. Only with the advent of the Boeing 747 and the Lockheed C-5 Galaxy, both designed two decades later, did American aircraft capable of lifting a heavier payload become commonplace.
Beginning with the B-36D, Convair added a pair of General Electric J47-19 jet engines suspended near the end of each wing; these were also retrofitted to all extant B-36Bs. Consequently, the B-36 was configured to have 10 engines, six radial propeller engines and four jet engines, leading to the B-36 slogan of ยซsix turnin' and four burnin'ยป".
