WebIn this design, the fissile material is shaped into a single sphere with a mass slightly less than critical (Figure \(\PageIndex{3}\)). Layers of carefully shaped high explosives surround the sphere. When the explosives are detonated, the force of the shock wave compresses the fissile material into a smaller volume, forming a supercritical mass. small red mall
