A torpedo that uses significantly smaller amounts of antimatter (1/2 Kg as opposed to 2 KG) and a larger amount of Krellium in order to increase the yield to Approximately 150 Isotons, or that of a normal antimatter torpedo. The Krellium has a stable crystalline matrix, until it is overloaded with energy, in this case provided by the Antimatter charge. This crystalline matrix then releases all of its potential energy in one burst, increasing the yield without increasing the amount of radiation released, making it useful in planetary assaults. In addition, the yield can be adjusted to minimize or maximize the damage as needed.
