 ===History=== ===History===
?''Yamato'' (大和) was the lead ship of the ''Yamato''-class of Imperial Japanese Navy World War II battleships. She and her sister ship, ''Musashi'' (武藏) , were the heaviest and most powerfully armed battleships ever constructed, displacing 72,800 tonnes at full load and armed with nine 46 cm (18.1 inch) 45 Caliber Type 94 main guns. Neither ship survived the war. 
  
?Named after the ancient Japanese Yamato Province, ''Yamato'' was designed to counter the numerically superior battleship fleet of the United States, Japan's main rival in the Pacific. She was laid down in 1937 and formally commissioned a week after the Pearl Harbor attack in late 1941. Throughout 1942, she served as the flagship of the Japanese Combined Fleet, and in June 1942 Admiral Isoroku Yamamoto directed the fleet from her bridge during the Battle of Midway, a disastrous defeat for Japan. ''Musashi'' took over as the Combined Fleet flagship in early 1943, and ''Yamato'' spent the rest of the year, and much of 1944, moving between the major Japanese naval bases of Truk and Kure in response to American threats. Although present at the Battle of the Philippine Sea in June 1944, she played no part in the battle.+====Design====
 +The ''Yamato''-class battleships were the next class of warships designed by the Japanese Navy after a long hiatus due to the ratification of a plethora of interwar naval treaties. But by the 1930s, Japan’s increasingly expansionist policies came under scrutiny by the League of Nations. To the world’s shock, Japan decided to withdraw from the League, which also meant she didn’t have to adhere to the aforementioned treaties. The Government understood that her empire would come into conflict with the United States, and devised plans for countering this new, potential threat. Knowing that Japan couldn’t out-produce the US, the IJN opted to make individual ships that were superior to their US counterparts.
 + 
 +Design work on this new class of battleships commenced in 1934, the year Japan pulled out of the League. The ambitious project started out with a selection process of 24 designs. The three most integral components were the ones that were under intense selection: armour, armament, and propulsion. The ideas for propulsion were uncharacteristically creative at a time when turbine power was staple. Many considerations of diesel and hybrid-diesel systems were considered due to the promise of greater endurance. Ultimately, it was narrowed down to conventional turbine propulsion, as previous experimentation with diesel propulsion for a capital ship proved problematic. The system – at such a scale – was highly unreliable, and to replace major components required the removal of many appliqués of armour. As well, the displacement was finally pegged at just under 66,000 tonnes, making this the largest battleship ever constructed, and with such allocation of space, the designers were able to authorize the implementation of 18.1”-calibre guns as opposed to a more traditional choice of 16” guns. By 1937, the designs were finalized, and the construction of 5 ''Yamato''-class battleships was planned.
 + 
 +The ships were imposing beasts; as ambition fuelled much of the design process. From the get-go, the idea was for such a vessel to engage multiple capital ships simultaneously. To do so, it required the armour to maintain sustaining power in a firefight. The belt was no less than 16”, and the bulkheads were a tad thinner at 14”. The top was capped with a plate about 9” thick, made of composite materials consisting of a variety of composite materials consisting of various heavy metals; not traditional rolled homogenous steel. Furthermore, the armoured deck incorporated sloping to save on some weight without compromising on protection. But the thickest plates were not on the sides, but found on the faces of the turrets, at an impressive thickness of 26” at most; they were truly impregnable from the front. The novel technique of arc welding was used in the construction process. Its use was justified, as not only was the seams between the armour plates were even tighter, but it also allowed for designers to attach a larger lower armour belt than with previous methods.
 +The scheme was not perfect though. While the torpedo protection system on paper looked impressive on paper, in actuality the performance was subpar. The bulges were adequate in their performance, but the seam between the upper and lower belt was directly underneath the bulge, which was shown to be prone to rupture upon impact.
 + 
 +To move such a heavy vessel, the class used 12 Kampon oil-fired boilers, which fed to 4 turbines. This generated an impressive 150,000 shaft horsepower, but it was not enough to break the 30 knot mark; shy by three knots. This was a compromise the designers were willing to take, but went against their venerated belief of speed is key. This drawback prevented the battleships to keep pace with fleet carriers in combined-arms action, as fuel consumption would be unsustainable.
 + 
 +The most characteristic feature of these massive ships was their choice in armaments. Welding nine 18.1” guns in three triple-turrets; two super firing in the front, and one facing the rear. This gave the battleships the ability to hurdle 13 tonnes on ordinance onto a target up to 42 kilometers away at a pace of 1.5 - 2 salvos per minute. The hope was that such firepower would be sufficient to deter aggressors from taking action; a feat of intimidation not hard to believe. Supplementary, the ships initially carried twelve 155mm dual-purpose guns in the form of six twin-gun turrets; three on each flank of the main superstructure. Additionally, the ''Yamato''-class carried a dozen 127mm AA guns in six dual-mounts, and twenty-four 25mm AA guns in eight triple-mounts for defence. By 1944 it was understood that the anti-aircraft firepower of these ships were severely handicapped, and the class underwent modifications. Two of the secondary turrets were removed, and in their place, another 12, 127mm guns were added and a whopping 138, 25mm guns were added.
 + 
 +''Yamato'', named after the Yamato Province, was the lead-ship of her class. Built by the Kure Naval Arsenal, she was laid down on 4 November 1937. She was launched 8 August 1940 and commissioned 16 December 1941.
 +====Service====
 +Throughout 1942, she served as the flagship of the Japanese Combined Fleet, and in June 1942 Admiral Isoroku Yamamoto directed the fleet from her bridge during the Battle of Midway, a disastrous defeat for Japan. ''[[Musashi]]'' took over as the Combined Fleet flagship in early 1943, and ''Yamato'' spent the rest of the year, and much of 1944, moving between the major Japanese naval bases of Truk and Kure in response to American threats. Although present at the Battle of the Philippine Sea in June 1944, she played no part in the battle.
  
 The only time ''Yamato'' fired her main guns at enemy surface targets was in October 1944, when she was sent to engage American forces invading the Philippines during the Battle of Leyte Gulf. On the verge of success the Japanese force turned back, believing they were engaging an entire US carrier fleet rather than the light escort carrier group that was all that stood between the battleship and the vulnerable troop transports. The only time ''Yamato'' fired her main guns at enemy surface targets was in October 1944, when she was sent to engage American forces invading the Philippines during the Battle of Leyte Gulf.

Yamato — Japanese Tier X battleship.

The biggest warship of World War II and the world's largest battleship. Yamato was designed around the idea that an individual ship could have superiority over any battleship of a potential enemy. Her main guns had overwhelming firepower. The ship maintained a very high level of survivability due to reliable armor and robust torpedo protection. Yamato’s AA capabilities were highly efficient due to carrying numerous AA artillery guns.

Player Opinion

Performance

The pinnacle of all Japanese battleship design philosophy and possibly of the entire world, Yamato gains its place as the most solid battleship at her tier. She has the second largest hit points of any ship in the game at a staggering 97200 next to Großer Kurfürst’s 105k and her guns have the highest citadel hit damage of any round in the game, at 14800 HP per citadel hit. The AA suite aboard matches her size and potency, with nearly 150 25mm AA barrels (in real life, 162 25mm AA barrels in latest upgrade). With a turning radius of 800m and a top speed of 27.2 kts, she is also surprisingly maneuverable despite her large size, but with a long rudder shift time and extremely slow turret traverse, one must plan all actions in advance, or risk being caught off-guard and unable to react. The guns, while accurate, are very unforgiving, with a 30 second reload stock, which can be decreased to just under 27 seconds at the expense of further reducing its abysmal turret traverse further by using a piece of equipment. Being one of the biggest ships in the game, Yamato is constantly targeted by Aircraft Carriers, and despite the numerous AA guns, high tier carriers can still get planes through, so it is advised to stay near ships that have solid AA suites such as cruisers for an AA "aegis" to be created. In addition, even though your armor is the most solid in the game you should still try to angle your ship as sometimes shells may have a chance to hit home and deal glaring damage. Keep in mind that her citadel can easily be hit if the enemy manages to penetrate your armor.


Pros:

  • Unrivaled main battery guns that can even penetrate other battleships at close range when they're bow on.
  • Extremely good dispersion, but landing hits on targets beyond beyond 18km is still challenging.
  • Second largest health pool and heaviest armor in the game.
  • Large quantity of secondaries can easily kill a destroyer at very close range.
  • Surprisingly good agility for its size.
  • Impressive torpedo bulge as long as torpedoes hit her torpedo belt.
  • Longest main battery stock range in the game.
  • Insane turret armor that deflects most things other then tier X BB shells at point blank.
  • No ship is safe when facing Yamato's guns, even Yamato itself; they are so big that they can even score cidadel hits on bow-on ships (due to overmatching rule)!
  • Firing from a distance of over 20 km will form an immunity zone that helps deflects AP shell effectively, but don't expect to score hits against enemy reliably.

Cons:

  • Extremely large size but still smaller than Izumo and Großer Kurfürst.
  • Very high notoriety and potential danger makes her a priority target for the enemy team.
  • Extremely slow turret traverse rate of 72 seconds for traversing 180 degrees.
  • Poor shell velocity of the main battery makes it difficult to hit distant targets.
  • Long rudder shift time.
  • The huge majority of her AA defenses are short range, rendering her defenseless against planes before they drop their payloads. Her 127mm guns have underwhelming AA damage output.
  • Despite her citadel being well armored, its large size and hexagonal shape means she is still very vulnerable to any sorts of citadel damage from any angle

Research

As a Tier X ship, Yamato has no additional modules to research.

Optimal Configuration

Upgrades

Yamato`s strengths lie in her immensely powerful main guns and fearsome secondaries. The two most popular builds for Yamato focus on improving the capabilities of her already powerful main guns, and to amp up the power of her secondaries.

Main Gun Build: To improve Yamato`s main gun performance, Main Armaments Modification 1 is recommended to reduce the likelihood of her turrets being knocked out, with Aiming Systems Modification 1 in slot 2 to increase their accuracy. Main Battery Modification 2 can be viable as Yamato's turrets can be painfully slow, but this sacrifices precious reload speed. For slot 3,Main Battery Modification 3 instead sacrifices turret traverse speed for an improved rate of fire, allowing her to fire - and theoretically hit - enemy ships more often. Gun Fire Control System Modification 2 isn't really necessary, as Yamato already have the highest base gun range in the game.

Secondary Build: To amp up Yamato`s fearsome secondaries even further, , Auxiliary Armaments Modification 1 is a must to greatly improve the surviveability of your secondaries, Secondary Battery Modification 2 to greatly increase the range of her secondaries (as by now they should be at a range of 8.4km, Advanced Firing Training will take this above to 10.1km) which also decreases their dispersion by 20%, and finally Secondary Battery Modification 3 to improve the rate of fire of her secondaries.

For her other three slots, Damage Control System Modification 1 is almost a must for slot 4, as Yamato`s engines and steering will almost never be incapacitated, and she'll have to deal with fires and flooding more often. For slot 5, all three choices of Damage Control System Modification 2 to reduce the duration of fires and flooding, Steering Gears Modification 2 to increase Yamato's sluggish rudder speed, or Propulsion Modification 2 to improve her propulsion to maximum speed, are viable options and depend on her Captain's personal playstyle. Finally, Target Acquisition System Modification 1 is a good choice to increase her acquisition radius of torpedoes, which can be almost impossible to dodge if not spotted as soon as possible. While Concealment System Modification 1 can be useful, once she's fired her guns Yamato can be spotted from over 30km away, making concealment redundant.

Commander Skills

Consumables

Players can equip the following consumables on Yamato: ​Damage Control Party, Repair Party, and a choice between Spotting Aircraft and Catapult Fighter. It is strongly recommended to take the Premium versions of ​Damage Control Party and Repair Party to maximise surviveability.

Camouflage

Type 1, 2, or 5 camouflage can be equipped for credits; Types 2 or 5 are recommended at a minimum to reduce the accuracy of incoming shells.

Players who wish to spend doubloons can equip Yamato with Type 20 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, increases her credit earnings, and increases the amount of experience she earns.

Signals

As with all battleships, Yamato comes with 8 signal flag slots. The three most important flags are India Delta, Juliet Yankee Bissotwo and India Yankee; all of which will improve your surviveability. If the captain goes with the Secondary Build, the addition of Mike Yankee Soxisix will further improve the performance of Yamato`s secondaries.
