The primary weapon of a large battleship, based on Wave Cannon technology. Though it boasts to have the truly monumental power to destroy a planet, this has yet to be proven; considering that the Bydo haven't used this fearsome capability yet suggests that perhaps it doesn't. The weapon can charge a powerful beam in a few seconds, easily more powerful than any R-craft. As might be expected, the Planet Buster can take a beating before being destroyed.
Main gun for giant warships. Basically the same as a R-9 Wave Cannon... Just 100 million times more powerful. At full charge, it really can destroy a planet, but charging takes time and movement after shooting is unpredictable.
