Aircraft - B-36 (U.S.A.)

The B-36 was a much larger than the B-29 (which dropped the atomic bomb on Japan).  The first B-36A's were delivered in 1948.  They were used exclusively for training.  B-36B's were not fully operational until 1952.  It could carry a variety of ordinance including nuclear weapons, and the "Peacemaker" was a major player in the Cold War.  The Air Force accepted a total of 383 B-36s, including prototypes, service test aircraft, and reconnaissance aircraft, but not including the two B-36Gs delivered as YB-60

The WADC helped make many modifications to the aircraft to serve different purposes, and research conducted on the B-36 helped the WADC in the development of the B-52, which replaced the B-36 throughout the mid to late 1950's.

The NB-36H carried a nuclear reactor that was used by the WADC to do radiation shield testing.  The reactor did not power the aircraft.
