The Convair NB-36H was a bomber that carried a nuclear reactor. It was also known as the "Crusader".[1] 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.

Design and development

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. [2][3][4][1] 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.[1]

Flight events

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[5] over New Mexico and Texas. Although it was never needed, there was a direct hotline to the President's office set up in case of a nuclear accident on board the aircraft.
