Type-221 large-scale defensive particle cannon

The Type-221 large-scale defensive particle cannon, colloquially known as the Yamato cannon, is a particle weapon designed and produced by Sukimoto for planetary defence purposes. Commonly mounted on orbital defence platforms, Yamato cannons generate dense magnetic fields to harness a controlled nuclear reaction, focusing the energy of a gigaton nuclear explosion onto a single point, capable of obliterating most targets with single or few shots. Yamato cannons require massive amounts of energy to operate, thus limiting their use to orbital defence.
