Ships of U.S.A.
The United States inherited many of its nascent naval traditions from the British, from whom they won their independence in 1776. Over the years, the fledgling American navy encountered various hurdles and successes in its conflicts with the British, French, and Spanish navies. However, a mix of poor economic outlook, isolationist sentiments and post-World War I naval disarmament treaties reduced the effectiveness and preparedness of the USN for the Second World War. All of that changed after Japan's 7 December 1941 surprise attack on Pacific Fleet headquarters at Pearl Harbor, Hawaii. Regarded as an underhanded sneak attack outside the rules of civilized warfare, Pearl Harbor evaporated any reluctance of the American public to go to war.
With its battleship fleet crippled by the Pearl Harbor attack, the USN turned to submarines and its fledgling aircraft carrier fleet — the very weapons that the IJN had used in their attempt to neutralize the USN Pacific Fleet — and ironically put them to greater effect than the Japanese (who stuck to battleships and the "decisive battle" doctrines), achieving successes in the battles of the Coral Sea, Midway, the Philippine Sea, Leyte Gulf, and Okinawa. While slightly behind their IJN counterparts at the onset of the war, the USN gradually caught up both qualitatively and quantitatively; virtually every class of vessel was outfitted with superior fire control equipment such as radar and ballistics computers; the industrial might of the United States produced large numbers of proven designs (the 175 ships of the Fletcher class built within the space of less than four years being a prime example) with little unnecessary variation in equipment, so that crew transferred between ships could quickly fill their roles without specialized retraining. The US Navy emerged from World War II as the most powerful navy in the world, a title it still holds to this day.
Destroyers
Gameplay
The play style of American destroyers is best summarized as "annoy and harrass"; their fast-firing guns in quick-turning turrets can continuously rain fire on opponents with impunity while under cover of smoke or vision blockers such as islands (or simply out of vision range). Tier X Gearing, the crown jewel of USN destroyers, can blanket her targets with more than 120 rounds per minute. Unfortunately, slow shell velocities and incredulously high shell arcs, while allowing captains to fire over islands, make it near-impossible to hit anything but the largest of targets beyond medium ranges. They also have reasonable anti-aircraft firepower, allowing them to play the role of escort ship when the need arises; fire discipline and astute 연막 생성기 (
) usage are required, since gun and anti-aircraft battery fire can broadcast a ship's position. American torpedoes had variable speed settings; in World of Warships, only the high-speed setting is available (with the exception of Tier VII premium Sims). In-game, this means that lower tier American destroyers, instead of stealthily launching a spread out of visual range, are forced to weather fire from their targets' primary and secondary batteries well before they come within torpedo range. However, starting with Mahan at Tier VII, it is possible to launch a torpedo salvo from beyond detection range, albeit still at shorter ranges than their Japanese counterparts. To put things in perspective, Americans have to wait until their Tier IX's Fletcher before they get torpedoes with 10km range; the Japanese achieve this range with Tier VI destroyers Hatsuharu and Fubuki... and both of them reload faster.
Cruisers
Gameplay
American cruisers are all about the guns; their primary battery, secondary battery, and anti-aircraft armament are superlative. Forgoing torpedoes after Omaha at Tier V, they are instead able to lay down an incredible hail of gunfire in almost any direction, due to the fast-firing guns located along the sides of their lower-tier ships, or in their fast-turning turrets at higher tiers. Any enemies — especially destroyers — that come within firing range and do not take evasive action are quickly sent to the bottom of the ocean, particularly after the line gains access to the 수색 레이더 (틀:Surveillance Radar 1) consumable at Tier VIII. Although the Japanese often have better range and firepower, the Americans have faster turret traverse, conventional layouts, and higher rates of fire; the high shell arc of some of their cruiser rifles — like their destroyer counterparts — is a double-edged sword, with a plunging trajectory hampered by their unimpressive shell velocities. Their anti-aircraft batteries easily dissuade aircraft from venturing too close or even approaching if they're not massed together for protection; yet even then, a well-timed 대공 사격 (
) will quickly deplete the assets of enemy aircraft carriers. The American cruiser line splits after Omaha into a heavy cruiser branch - starting with Pensacola and topped by Des Moines - and a light cruiser branch starting with Dallas and topped by Worcester. Des Moines is the very pinnacle of the all-gun cruiser, as she has a very powerful anti-aircraft suite and main batteries that have unrivaled rate of fire. Worcester has rapid-fire guns, many consumables, and a great AA suite, which gives her unparalleled versatility on the battlefield.
Battleships
Gameplay
American battleships follow more orthodox and consistent designs: while their guns may not be as large and powerful as those of the IJN, the USN ships make up for it by having more guns that fire more often, giving them unmatched broadside firepower. Their anti-air suites are also fairly decent at staving off aerial assaults, although it's still recommended to have cruiser escort. In spite of inferior firing ranges and poor mobility, American battleships are capable of absorbing major damage in order to bring their guns to bear—their citadel armor is impenetrable to all but the largest caliber shells (at the cost of having a more lightly-armored bow and stern). Moving up the tech tree, their mobility progressively improves and catches up with the Japanese with the North Carolina at Tier VIII, and their AA firepower grows to the point that they either become practically immune to all but the most concentrated of air attacks, or the aircraft will not survive the return trip. From Tier III to IX, American battleships enjoy a better repair party consumable than other nations, excluding the british, giving the line better durability. The Tier X Montana is the pinnacle of the American battleship line: the evolution of the Iowa-class battleship design whose construction was cancelled some time after receiving congressional approval for construction in order to focus more on aircraft carrier production.
