This was no theoretical research project.

What's the difference between an atomic bomb and a nuclear bomb?

A nuclear bomb is a bomb that uses nuclear fission which is the splitting of an atom into two or more particles and nuclear fusion which is the fusion of two or more atoms into one large one while an atomic bomb is a type of nuclear bomb that uses nuclear fission.
