North Carolina — American Tier VIII battleship.

The inaugural series of a new generation of American battleships which began to be designed in the mid-1930s. Their primary advantage over "conventional" battleships lay in their significantly enhanced speed and more potent air-defense systems. During World War II, USS North Carolina played an active role in Pacific Ocean operations, participating in engagements such as the Battle of the Eastern Solomons, the Battle of the Philippine Sea, and the Okinawa landings. During the course of the war, the ship was awarded 12 battle stars.

USS North Carolina is now preserved as a military museum ship in Wilmington, North Carolina.

Player Opinion

Performance

Armament

North Carolina has access to nine accurate 406 mm guns. These guns have an impressive firing range of 23.26 km, which can be further increased with her spotting aircraft and the Artillery Plotting Room Modification 1 upgrade. Her guns can overmatch 27 mm of plating that is commonly found on cruisers at her tier. This allows North Carolina to deal consistent damage to most cruisers she faces. However, she may struggle to damage higher tier battleships.

North Carolina’s high accuracy allows her to effectively punish enemy ships at most ranges. However, her AP shells are floaty and require greater lead at range. She is the first American battleship to gain access to "Super-heavy AP shells", which trade poor velocity and short range performance for increased penetration at longer ranges.

North Carolina has access to both AP (armor piercing) and HE (high explosive) shells. The AP shells deal 13,100 maximum damage while the HE shells deal 5,700 maximum damage with a 39% fire chance. North Carolina should mainly fire AP, only switching to HE for enemy destroyers and angled higher tier battleships. The main guns reload in 30 seconds, which can only be reduced by the use of the Close Quarters Combat and Adrenaline Rush captain skills. Compared to her peers at Tier VIII, North Carolina has the main battery range and accuracy advantage with 2.05 sigma (meaning her shells are more likely to land where the player aims). North Carolina packs quite a punch for a Tier VIII battleship, being able to punish the enemy better compared to her counterparts.

North Carolina has slow turrets for her tier, taking 45 seconds to traverse 180 degrees. Battlefield knowledge and positioning will be important to make the best use out of her main battery.

Secondary Battery

North Carolina’s secondary battery consists of 10 twin-mounted 127 mm dual-purpose guns, with 5 mounts per side. They lack any improved dispersion, which makes them unreliable at hitting targets, and have a short 6.6 km range, low 5% fire chance, and slow 6-second reload for their caliber. Captains should avoid investing commander points and modules into North Carolina’s secondary battery and focus on her survivability and main guns. If captains decide to invest into her secondary battery, they can have a max range of 10 km, a reload time of 5.7 seconds, and a 7% fire chance.

Survivability

North Carolina has slightly improved deck armor (38 mm) compared to the standard 32 mm plating at Tier VIII, allowing her to survive longer against cruiser-caliber HE. She is otherwise covered in the standard 32 mm battleship plating and has a rather large superstructure, so captains should position carefully to help avoid heavy fire.

While North Carolina has enhanced deck plating, the rest of her armor is average. She will take heavy damage from large-caliber HE and AP shells while broadside. Her citadel is vulnerable while giving broadside, and the majority of battleships and even some cruisers can punish North Carolina if she’s broadside. This is somewhat mitigated by her enhanced heal. While not as strong as British battleships Lion and Conqueror, it allows her to recover more health compared to her peers. She has four charges stock or five with the Emergency Repair Expert captain skill. She has an average healthpool for her tier (66,000) and subpar torpedo protection (19%). North Carolina has great concealment for her class at 15.2 km base, which can be reduced to 12.3 km with the Concealment System Modification 1  upgrade and Concealment Expert captain skill.

Maneuverability

North Carolina is one of the slower battleships for her tier, doing 27.5 knots with her upgraded engine. Her rudder shift time is good for a Tier VIII battleship at 15.2 seconds which can be reduced to 12.2 with the use of Steering Gears Modification 1 . She has a tight turning radius for a battleship of her size, allowing her to evade incoming fire and torpedoes.

Anti-Aircraft

North Carolina has respectable anti-air capabilities for a Tier VIII battleship. She has a 5.8 km range and produces eight flak explosions. Her long range DPS is high for a Tier VIII battleship at 172, not nearly as high as Flandre but still respectable. Her short- and medium-range defenses are more powerful compared to her peers, at 308 and 389 DPS respectively.

North Carolina doesn’t have access to any consumables such as Defensive AA Fire to enhance her anti-air capabilities. If captains choose to build into her anti-air, they can increase the flak count to nine, the long range to 188 DPS, medium range to 427 and short range to 338. To further deter enemy aircraft attacks, North Carolina has the ability to swap her Spotting Aircraft consumable for a Fighter.

Her AA defenses can assist allies under attack by aircraft and will help mitigate some damage from Tier VI aircraft carriers, but it is not powerful enough to stop strikes from Tier VIII or Tier X aircraft carriers. If North Carolina is facing higher tier aircraft carriers, she should stick with her team to overlap AA cover.

Battle Performance

During battle, captains will instantly notice a major difference compared to the lower tier American battleships. North Carolina has the speed to switch flanks as needed and provide fire support for her team. Captains who have not yet played a ship with speed such as this one should be careful to not overextend, as mispositioning in this ship will lead to a quick return to port. North Carolina should make use of her great concealment and play around 13-14 km from the enemy. This will give her the best chance to punish enemy ships with her accurate guns while also giving enough distance that disengaging is not a problem.

Pros:

• 38 mm deck armor
• Excellent main battery range
• Powerful AP shells with high damage
• High sigma
• Good AA defenses
• Significant speed improvement over preceding ships
• Tight turning radius
• Excellent concealment
• Improved Repair Party consumable that heals more damage

Cons:

• Vulnerable citadel
• Poor torpedo protection
• Large superstructure
• Floaty AP shells with long flight times
• Slow turret traverse
• AA defenses can’t stop a strike from high tier carriers
• Many battleships can still outrun her

Research

Prioritize unlocking hull B for increased HP and rudder shift. Next, focus on the engine upgrade to improve her speed. Lastly, captains can research the range upgrade to increase main battery firing range.

History

Design

The North Carolina class was a class of two fast battleships, North Carolina and Washington, built for the United States Navy in the late 1930s and early 1940s. The navy was originally uncertain whether the ships should be fast enough to counter the Japanese Kongo class, which was believed by the United States to be capable of 26 knots (30 mph; 48 km/h), or should sacrifice speed for additional firepower and armor. The Second London Naval Treaty's requirement that all capital ships have a standard displacement of under 35,000 long tons (35,560 metric tons) prevented the desired objectives from being fully realized within its limits, and the navy considered over fifty designs before one was chosen.

Towards the end of this lengthy design period the General Board of the United States Navy declared its preference for a battleship with a speed of 30 knots (35 mph; 56 km/h), faster than any in US service or under construction, with a main battery of nine 14-inch (356 mm)/50 caliber Mark B guns. The board believed that such ships could fulfill a multitude of roles, as they would have enough protection to be put into a battle line while also having enough speed to escort aircraft carriers or engage in commerce raiding. However, the acting Secretary of the Navy authorized a modified version of a different design, which in its original form had been rejected by the General Board. This called for a 27-knot (31 mph; 50 km/h) ship with twelve 14-inch rifles in quadruple turrets and protection against guns of the same caliber. In a major departure from traditional American design practices, this design accepted lower speed and protection in exchange for maximum firepower. After construction had begun, the United States became concerned over Japan's refusal to commit to the caliber limit of the Second London Naval Treaty, so they invoked the "escalator clause" of that pact and increased the class' main armament to nine 16-inch (406 mm)/45 Mark 6 caliber guns from the original twelve 14-inch guns.

Service

Both North Carolina and Washington saw extensive service during the Second World War in a variety of roles, primarily in the Pacific theater where they escorted fast carrier task forces and conducted shore bombardments. North Carolina shot down between seven and fourteen Japanese aircraft in the Battle of the Eastern Solomons, and later sustained a torpedo hit from Japanese submarine I-15. During the naval battle of Guadalcanal —which was a chaotic night engagement — Washington’s radar-directed main batteries fatally damaged the Japanese battleship Kirishima and caused her to sink the next day. In February 1944, Washington crushed her bow in a collision with the battleship Indiana. Following repairs, Washington rejoined her sister for the Battle of the Philippine Sea.

After the end of the war, both ships took part in Operation Magic Carpet, the withdrawal of American military personnel from overseas deployments. The vessels were laid up in the reserve fleet until the early 1960s, when North Carolina was sold to her home state as a museum ship, and Washington was broken up for scrap.

In-game historical inaccuracies

• North Carolina has a unique permanent camouflage in that upgrading to Hull (B) will change the ship's camouflage pattern. Measure 12 is tied to Hull (A) while Measure 32 is tied to Hull (B).
• The Measure 12 camouflage was used by North Carolina in 1942. During this time she was armed with five quad 1.1-inch (28 mm) cannons. Hull (A) represents North Carolina after her November 1942 refit, when she was re-equipped with ten quad 40 mm Bofors. By this time she had been repainted with Measure 21 camouflage, which is overall Navy Blue with dark Deck Blue decks. This camouflage scheme should be on Hull (A) and it is currently missing.
• North Carolina’s original anti-aircraft complement of four quad 1.1"/75 (28 mm) cannons and twelve .50 caliber (12.7 mm) M2 Browning machine guns is not represented.
• Actual propulsion is 121,000 hp; the 100,000 hp downgrade was invented by WG.
• Actual speed was 28 knots in 1941 and 26.8 knots in 1945, due to the increasing number of AA gun mounts and electronics as World War 2 progressed.
• The Measure 22 camouflage applied to North Carolina from 1945-1946 is missing.
• The 5"/38 caliber gun's actual rate of fire is 15 rounds per minute; North Carolina’s is 10 rounds per minute. Only Massachusetts has the correct rate of fire.

Historical Gallery

• 

  The 32,250-long-ton (32,770 t) design "A" was one of the first proposals. Unlike "B" and "C", it was far below the treaty-mandated limit of 35,000 long tons (36,000 t). It would have carried nine 14-inch (356 mm) guns in its main battery; although all of the turrets were forward of the superstructure, the guns could still fire forward provided that they were elevated to 4.5 degrees or more. The secondary battery planned was twelve 5-inch (130 mm) unusually arranged in triple mounts.

• 

  "F" was an attempt to create a viable combination of an aircraft carrier and a battleship. With regards to the treaty limits, the design had an extremely comfortable margin with a standard displacement of 31,750 long tons (32,260 t; 35,560 short tons). Three catapults were mounted on the bow, while a hangar located under that would contain ten bombers with wings folded. Two non-superfiring turrets would be mounted aft, both holding four 14-in guns.

• 

  "VII" harked back to the days of the slow battleships; with a top speed of 22 knots (25 mph; 41 km/h), it would have been only 1 knot (1.2 mph; 1.9 km/h) faster than the old ""standard" battleships. The weight gained from reducing the speed was added back in firepower and protection: "VII" would have had twelve 14-inch/50 caliber guns in four triple turrets and an immune zone against its own 14-inch gun between 21,400 and 30,000 yards (12.2 and 17.0 mi; 19.6 and 27.4 km).

• 

  "XVI" was one of the final proposals; after "XVI-C" was rejected, a modified version of this design was chosen for the North Carolinas. There were a few major differences between this and the final plan. For example, all exhaust was eventually trunked into two funnels as opposed to one, and the 5-in/38 caliber secondary battery was composed of all dual-mounted guns (no single).
