"First mentioned in Halo: First Strike, the NOVA is a special device that uses nine fusion warheads in a ring formation. Once detonation occurs, the lithium-triteride fusion cores combine together and the resulting blast is multiplied one hundred-fold. Nick-named "planet-killers," these have enough explosive power to destroy an entire planet."
