The Disruptor Torpedo is a powered projectile with a warhead that creates random and unstable mass effect fields when triggered. These fields warp space-time in a localized area. The rapid asymmetrical mass changes cause the target to rip itself apart.
In flight, torpedoes use a mass-increasing field, making them too massive for enemy kinetic barriers to repulse. The extra mass gives the torpedoes a very sluggish acceleration, making them easy prey for defensive point-defense weapons. So, torpedoes have to be launched at very close range.
Torpedoes are the main anti-ship weapon used by fighters. They are launched from point-blank range in "ripple-fire" waves reminiscent of the ancient Calliope rocket artillery launchers (thus their popular nickname "Callies").
