Canada’s 1948 plan of sending an atomic rocket ship to the moon a dozen years later obviously never came to fruition, but if the project had proceeded in a timely manner it would have blasted off just prior to the Limited Test Ban Treaty of 1963, which forbid such space exploration. In addition to investigating the sphere, the country had in mind to use the moon as a launch pad to reach other planets and a base from which to rain missiles over regions of Earth in times of war. Yikes.
A report on the proposed mission appeared in the August 29, 1948 Brooklyn Daily Eagle.
