USS Michigan and her sister ship USS South Carolinawere the first dreadnoughts of the US fleet. Eight 12in (305mm) artillery guns on Michigan were divided between four turrets: two fore and two aft. The turrets were placed in a superfiring arrangement where one turret was mounted slightly behind and above the other—quite an innovation for those times.
Unlike her Japanese counterpart Kawachi, she could use all her guns to fire a full broadside. As to her maximal speed, it left much to be desired: she would not go faster than 18 knots.
USS Arkansas carries guns of the same caliber as her predecessor, but her firepower is significantly increased. The ship has twelve guns installed in six turrets. The layout of the turrets is quite unique: two of them are mounted forward, two aft, and two amidships. As a result, bow guns and after guns can fire straight and sideways, while central turrets can only fire sideways. The ship has the same level of armor as her predecessor Michigan, however her speed is increased to 21 knots.
V New York
The first super-dreadnought of the US Navy. She carried new more powerful and long-range guns with a caliber of 14in (356mm). Engineers had to give up one of the gun mounts to not exceed the designed displacement. The ship is armed with ten guns installed in five turrets.
Other than that, New York is very similar to her Tech Tree predecessor; even the speed remained the same—21 knots.
VI New Mexico
The first “standard” battleship of the Tech Tree armored according to the “all or nothing” concept. The ship’s citadel is covered with a 13.5in (343mm) armor belt that can withstand large-caliber hits. Antiaircraft armaments also moved to a new level—USS New Mexico carries powerful 5in (127mm) antiaircraft cannons.
Unfortunately, all these improvements come at a price of very low maneuverability. The same speed of 21 knots also leaves much to be desired.
A new battleship and a new stage of US naval artillery development. USS Colorado boasts eight super powerful 16in (406mm) guns. The battleship inherited most of her predecessor’s advantages and improved upon them. She has equally powerful armor able to withstand large-caliber hits. A battery of 5in (127mm) antiaircraft cannons makesColorado a formidable adversary to aircraft carriers.
VIII North Carolina
This battleship has a little less armor compared to Colorado, but she gained maneuverabilitymaneuverability instead. The increased speed of 27 knots allows USS North Carolinato act in a tactical formation with aircraft carriers and cruisers, and be more fast and agile in a battle. Powerful auxiliary armament is one of this ship’s strengths. She carries a battery of 5in (127mm) dual-purpose guns that are perfect to fight off light ships and enemy aviation.
Engineering solutions used in USS North Carolina were further elaborated in USS Iowa.Iowa is a powerful and high-speed battleship capable of fighting in mobile task forces together with aircraft carriers and cruisers.The ship managed to maintain the same excellent speed and increase her defence and armor。
This battleship could have matched the legendaryYamato, if the project hadn’t remained on paper. The relatively low speed of 27 knots is compensated by increased armoring and excellent armament. While her predecessor Iowa has only three turrets, Montanacarries twelve 16in (406mm) guns in four triple turrets. Former dual-purpose artillery guns were replaced with more powerful and elaborate guns.
