With the space exploration, tosses tried to make their ships more and heavier and more protected. However, the meeting with swarm's agents, who relied on numerical superiority more than on the safety of their wards, forced tosses to take a step backwards. The appearance of corsairs made it possible to provide cover for heavier and more valuable ships, and also to create more mobile attack groups to respond to enemy tactics of pinpoint strikes. Corsairs attack only aerial targets.
To facilitate the ship they install weak weapons on it, and to preserve the effectiveness they add special destructors, which cause triple damage to power shields and 25% extra damage to organic targets.
