Corsair is the heaviest of the T1 ships. Their biggest advantage is their durable armor and versatility. They are equipped with a powerful long range plasma cannon and a depth charge launcher. Their large range allows them to outrange all ships and torpedo launchers, which make them a great choice for pushing forward the front-line. They are also a good counter against submarines. However, due to slow movement and low maneuverability, they can get easily overrun by lighter ships. It is a good idea to provide them with an escort of lighter ships and repairing support.
They are costly and leave very precious wrecks, so take good care of them!
Corsairs have lower costs, but also weaker damage, compared to their CORTEX counterpart (Oppressor).
