These big, slow missiles store power from the ship's sails, and then use it to power their own engines. Laser Torpedoes explode when they make contact with a ships hull, doing terrible damage. Nimble ships can often outmaneuver them, so get in close to ensure a succesful shot. As a Torpedo tracks the enemy target, it will detonate should a careless ally ship get in the way.
Pros: Very heavy damage, very long range, tracks moving targets.
Cons: Slow speed, very slow rate of fire.
