Damage Control

At some point in the game, your ship will take damage, be it in the form of a torpedo, bomb, or artillery hit. When this happens, your ship will lose health, and a leak, fire, engine failure, rudder or engine damage, weapon damage, or (if you're commanding an aircraft carrier) flight deck damage may occur. Several different types of damage can also occur at once. For example, a fire and flooding can both occur simultaneously. Leaks are the most dangerou of all these types of damage. Leaks slowly damage your ship in the same way a fire slowly damages a fuel tank or magazine area. The severity of the leak is dtermined by how many arrows are lit up when a leak occurs. One arrow means the leak isn't all that serious, whereas three arrows means there is a very large hole in the side of your ship which is almost certainly going to cause it to go under. A ship can suffer leaks from torpedo hits, shell hits, and (If you're in command of a destroyer, cruiser, or battleship with its main body destroyed) aerial bombs. The bar adjacent to the damage control interface is the damage bar. Once that bar is completely gone, it means that the main body of your ship is destroyed and that any new hits to the main body of the ship will automatically cause another leak.
