Convair B-36 Peacemaker airplane model. The USAF B-36, an intercontinental bomber, was designed during WW II. The airplane made its maiden flight on August 8, 1946 and on June 26, 1948 the Strategic Air Command received its first B-36 for operational use. By August 1954, when production ended, more than 380 B-36s had been built for the USAF.
In 1958-59, the B-36 was replaced by the more modern B-52. During the years it was in service, the airplane was one of America's major deterrents to aggression by a potential enemy. The fact that the B-36 was never used in combat was indicative of its value in "keeping the peace."
