A planet controlled by the Mokra Order in the Delta Quadrant possessed more than 85 phased ion cannon emplacements. In 2372, these cannons opened fire on the USS Voyager as it attempted to rescue its away team from the surface. The starship was able to evade the cannon fire for a few minutes by hiding in a magnetic storm over the north part of the planet, which confused the cannon's targeting sensors. (VOY: "Resistance")
