The Convair X-6 was a proposed experimental aircraft project to develop and evaluate a nuclear-powered jet aircraft. The project was to use a Convair B-36 bomber as a testbed aircraft and though one NB-36H was modified during the early stages of the project the program was cancelled before the actual X-6 and its nuclear reactor engines were completed. The X-6 was part of a larger series of programs costing US$7 billion in all that ran from 1946 through 1961.
Made by Convair.
