Simply stated, it is a bombardment ship. It can stand off at distance, circling its target counterclockwise, lobbing endless barrages of proximity torpedoes, or if the captain is daring, attempt to close to overload range and do the same.
In fleet actions this ship can get into trouble if enemy ships can maneuver to stay away from the port side.
This ship is particularly useful against stationary targets; not so useful against targets that are fast and maneuverable. You would want an escort(s) in fleet actions.
