Starting off from Tier III, all battleships have access to the Repair Party consumable, allowing them to repair some damage taken during battle and giving them unmatched survivability. As captains progress up the tiers, battleships gain access to additional abilities: Spotting Aircraft, which launches an unarmed spotter plane for the battleship, increasing the range of her already long-range main guns by 20% (at 32km, Yamato can basically fire on enemies across the entire map) and patrols in an area around the battleship, revealing nearby enemies that would have been otherwise hidden from sight; Catapult Fighter launches fighter aircraft from the battleship's catapults that escorts the battleship and engages enemy aircraft that wander too close. Remember that these two abilities can be prematurely shut down by shooting down the aircraft; and German battleships have access to Hydroacoustic Search starting at Tier VIII, giving them greatly increased spotting range for incoming torpedoes.
Large, well-armored warships brandishing massive, main guns and numerous secondary and defensive AA batteries, battleships are the heaviest, and some of the most powerful ships in the game. They can rain fire upon enemies with impunity due to their long gun ranges, weather more fire than any other class, and their secondary batteries make short work of any smaller ships or aircraft that foolishly attempt to close the distance without the use of tactics. Unfortunately, slow rudder shift times, coupled with long turning times of the main battery turrets, render them unable to respond quickly to rapid changes in the battlefield; it is recommended for battleship commanders to think several steps ahead before taking any action, especially when facing the battleship's biggest weakness, the torpedo. Forget about subtlety; battleships can be seen from miles away, even without firing, but with a well-placed salvo, they can cripple any enemy they encounter, if not outright kill them. However, as shown in history and reflected accordingly in-game, lone or unescorted battleships are nothing but sitting ducks for enemies to pounce upon and overwhelm, especially by destroyers and aircraft carriers.
