Planet-splitter

A planet-splitter missile was a weapon used by the Daleks which could devastate an entire planet. During the First Dalek Incursion of the Second Dalek War, the planet Arkheon was hit by a "Planet-splitter" missile. The missile strike destroyed half of the planet, exposing the core. The fallout from the missile strike killed most of the Arkheonite inhabitants. (PROSE: Prisoner of the Daleks)
