The Convair NB-36H was a bomber that carried a nuclear reactor. It was also known as the "Crusader". It was created for the Aircraft Nuclear Propulsion program, or the ANP, to show the feasibility of a nuclear-powered bomber. Its development ended with the cancellation of the ANP program.

The NB-36H was converted from a B-36H that had been damaged by a tornado. The original crew and avionics cabin was replaced by a massive lead- and rubber-lined 11 ton crew section for a pilot, copilot, flight engineer and two nuclear engineers. Even the small windows had 10-12 inch thick lead glass. Unlike the planned Convair X-6, the three-megawatt air-cooled reactor in the NB-36H did not power any of the aircraft's systems, nor did it provide propulsion, but was placed on the NB-36H to measure the effectiveness of the shielding.

The NB-36H completed 47 test flights and 215 hours of flight time (during 89 of which the reactor was operated) between September 17, 1955, and March 1957 over New Mexico and Texas. Although it was never used, there was a direct hotline to the President's office set up in case of a nuclear accident on board the aircraft.
