Depth Charge Thrower
About this technology
A simple mechanical device that tosses a depth charge a set distance away from the ship. This means that the destroyer no longer has to drive directly across the target to hit it. Mounting this module on Light Ships and Cruisers will allow them to attack enemy Submarines.
