During World War I sinking a enemy battleship was a 3-step process. First, locate your target's position and plot its course. Second, determine the battleship's speed and confirm the direction in which it's heading. Last, launch torpedo not directly at the ship, but where you think it’s going to be by the time the torpedo reaches the ship.
