Puerto Rico — American Tier X cruiser.

The design project that preceded the creation of the "large Alaska-class cruisers". The CA2-D variant was designed with twelve 305 mm main battery guns.

Puerto Rico was the reward for the first Dockyard event during Christmas 2019, and returned as the reward for the Dockyard event starting in Update 0.11.7. She has not been available outside those two Dockyard events. (A few were available during a charity event in early 2022, where successful bidders were in the $800+ range.)

Summary

Puerto Rico is a Tier X American large cruiser. Compared to her Tier IX relative Alaska, Puerto Rico offers slightly improved protection, a fourth main gun turret, as well as superior Anti-Air protection.

Armor and survivability

Puerto Rico is a well-protected ship, similar to her US larger cruiser counterparts. Her HP pool is massive for a cruiser, nearly on par with some battleships. She sports a relatively thick 27mm bow and stern armor, enough to bounce up to 381mm caliber AP shells when angled properly. Her 38mm deck armor is also relatively thick, resisting most 203mm HE shells and bouncing all battleship AP caliber shells. Perhaps Puerto Rico 's most striking armor feature is her excellent citadel protection. With a completely submerged citadel and a thick 254mm belt armor, her citadel is nearly impossible to hit even when showing flat broadside to the enemy. This lets Puerto Rico get away with mistakes that would sink other cruisers. Thanks to her relatively generous torpedo protection, she takes notably less damage from torpedoes than other cruisers. Puerto Rico 's only weaknesses are her large size and 60-second fire duration, the result of her large cruiser status. Despite these flaws, Puerto Rico overall is a very sturdy ship and will prove very difficult to kill.

Main Armament

Puerto Rico is armed with the same twelve 305mm rifles used on her lower tier cousins Alaska and Congress. The 305mm guns can be thought of as scaled-up versions of the US 203mm heavy cruiser guns, sharing many general characteristics. These guns fire powerful AP shells, sporting improved penetration angles, good armor penetration, and dealing heavy damage. Her HE is also potent as it can penetrate up to 51mm of armor, commonly found on heavily armored battleships and cruisers. Combined with twelve guns, Puerto Rico offers one of the heaviest broadside salvoes of any cruiser in World of Warships, dealing heavy damage to any vulnerable target she finds. Aiming her guns is similar to the German cruiser Hindenburg as they share similar shell flight times at all ranges.

While Puerto Rico 's salvoes hit hard, they are offset by her relatively poor accuracy and slow reload. Unlike other cruisers, Puerto Rico guns uses the less accurate battleship dispersion formula. Though she has a higher than average sigma of 2.2, the significantly larger dispersion area results in fewer hits at long range compared to other cruisers. Her slow reload also hurts her damage output, sometimes unable to fire a second salvo before the target disengages. Her 18.8km gun range is generally sufficient for most maps, though this can be inadequate in certain situations or maps. Though Puerto Rico doesn't have the same overall damage output as other Tier X cruisers, she makes up for this by severely punishing anyone who shows broadside to her.

Like other US high-tier tech tree cruisers, Puerto Rico lacks any sort of torpedo armament. While she carries several 127mm/54 guns as her secondary armament, their inaccuracy means they contribute little to any fight. As a result, Puerto Rico is vulnerable at very close ranges as her main guns only get a few salvoes to kill the enemy before they ram or torpedo her.

Anti-Air Defense

As expected of US cruisers, Puerto Rico carries a respectable AA suite. Her AA suite is effective at all ranges, though with an emphasis on close and mid-range firepower. While this isn't enough to stop carrier attacks outright, it can shoot down a lot of enemy planes and discourage future follow-up strikes. Slotting Defensive AA Fire  will improve her AA effectiveness, though it is mutually exclusive with the Hydroacoustic Search  as they share the same consumable slot. Her torpedo belt helps significantly against torpedo attacks, though she remains vulnerable to dive bomber attacks due to her large size. AP bombs can easily land citadel hits due to her inadequate citadel roof protection. Overall while Puerto Rico carries significant anti-air firepower, it is not enough to survive against determined Tier X carrier attacks. Players should still utilize friendly AA support whenever possible.

Maneuverability

Due to her large hull, Puerto Rico is a cumbersome ship by cruiser standards, handling more like a battleship. With a large turning radius and sluggish rudder shift time, Puerto Rico cannot quickly react to incoming threats such as torpedo salvoes. While her top speed is average, this does not save her from having poor overall maneuverability. Instead, Puerto Rico relies on her armor to block enemy shells rather than dodging them entirely.

Concealment

Unlike many other US cruisers, Puerto Rico 's concealment is relatively poor. Even with all the concealment reduction skills and upgrades, Puerto Rico can only lower her surface and aerial detection down to 13.0km and 9.0km respectively. Some battleships will even out-spot her, making her difficult to position effectively. The large surface detection radius also hurts her radar effectiveness as it gives destroyers ample time to mitigate its effects. Enemy carriers can easily keep her spotted due to the large gap between her anti-air range and her air detection range. While not a complete deal-breaker, Puerto Rico 's poor concealment is a notable weakness that players must account for.

Battle Performance

Puerto Rico 's general playstyle is very similar to that of her Tier IX cousin Alaska, sharing similar hulls, gun characteristics, and consumable loadout. Alternatively, she can also be thought of as the large cruiser version of the Tier IX Buffalo. In either case Puerto Rico is a versatile large cruiser that can be effective in nearly every situation. Though her optimal range is between 8-14km, oftentimes it is difficult to get close without coming under heavy focus fire. Her turret arrangement also makes her less suited to playing near islands, losing half her firepower whenever she is bow in. As a result, Puerto Rico should start most matches in a kiting position. This allows the player to whittle down the opposition while gaining more information on enemy deployment. Going to the flank is also a good idea as it creates crossfires between you and your allied battleships. Make sure to switch between HE and AP depending on the enemy orientation. AP is amazing for crushing broadside ships whereas HE deals consistent damage and fires to all targets.

If the enemy is sufficiently weak, then usually it is a good time to push. Puerto Rico performs well on the offense due to her durability and Surveillance Radar . Use islands or other cover to mask your approach; ideally you want to start the fight around 10km to press your close-mid range firepower advantage. Her 10km long-lasting radar excels at denying capture zones and catching ships in smoke. Even if the radar doesn't find anything, the threat of being radared alone can zone out enemy ships, decreasing their ability to damage you and your team. Once you have secured the objectives, you can either continue pushing to flank the other side of the map or switch to a kiting position if expecting a counter push.

Overall Puerto Rico is a solid versatile large cruiser, having good AP to punish other cruisers and radar to punish DDs. There is rarely a situation where she is truly helpless, making her a dangerous opponent throughout the match.

Pros:

• Massive HP pool for a Tier X Cruiser, comparable to Tier IX battleships
• Resilient armor scheme, very difficult to citadel
• Excellent torpedo protection, comparable to battleships in effectiveness
• Twelve 305mm rifles gives her a heavy broadside salvo
• Powerful AP shells with high base damage and improved penetration angles
• Access to 10km Surveillance Radar , a powerful tool against destroyers and smoke cruisers

Cons:

• Large hull, relatively easy to hit
• Mediocre accuracy and slow reloading, relying more on her high alpha strike to kill ships
• Lack of torpedo or effective secondary armament, hurting her effectiveness at very close range
• Large turning radius and very slow rudder shift time
• Poor concealment values, relatively easy to detect by other ships

Optimal Configuration

Upgrades

The recommended upgrades for Puerto Rico in Randoms are as follows:

• Slot 1: Main Armaments Modification 1  *
• Slot 2: Damage Control System Modification 1  *
• Slot 3: Aiming Systems Modification 1  *
• Slot 4: Steering Gears Modification 1  *
• Slot 5: Concealment System Modification 1  *
• Slot 6: Main Battery Modification 3  *

Slot 1: Main Armaments Modification 1 is highly recommended as it reduces the chance of her turrets getting incapacitated. Auxiliary Armaments Modification 1 is also a viable option as it helps the AA mounts survive into the late game.

Slot 2: There are several interesting build options in this slot. Of those, Surveillance Radar Modification 1 and Hydroacoustic Search Modification 1 are great choices as they increase the duration of their respective consumables. If the player does not have these upgrades, then Damage Control System Modification 1  is a viable alternative.

Slot 3: Aiming Systems Modification 1

Slot 4: This slot can address either her maneuverability or vulnerability to fires. Steering Gears Modification 1 is an excellent choice as Puerto Rico has the slowest rudder shift of all Tier X cruisers. Damage Control System Modification 2 is a good alternative if the player finds himself frequently on fire

Slot 5: Concealment System Modification 1  is the preferred option as reducing her concealment provides far greater improvements than any other option available.

Slot 6: For most players, Main Battery Modification 3 is recommended as it significantly speeds up her reload time. If the player finds the base gun range too short, Gun Fire Control System Modification 2 is a viable alternative though keep in mind her slow shells still make it difficult to land shells on target.

History

In the early 1930s, a new class of warship emerged: the super-cruiser. These warships would be specialized cruiser-killers - designed to be larger, more heavily armed, and more armored than their smaller, treaty-limited kin, these warships echoed the spirit of battlecruisers - armed well enough to defeat cruisers, while remaining fast enough to evade enemy battleships. Soon enough, the Kriegsmarine was constructing what would become the Deutschland-class Panzerschiffe, prompting the French Marine Nationale to begin the design of the Dunkerque-class battleships as a response - a "cruiser-killer-killer", effectively touching off the kind of arms race that the London and Washington Naval Treaties were designed to stop. It was these developments, as well as reports of a Japanese supercruiser project -- the B-65 -- which prompted the United States Navy to begin designing their own super-cruiser, what would become known as the Alaska-class. Ironically, it was the design of the Alaskas that prompted the IJN into beginning serious work on the B-65.

During the design of the Alaskas, a multitude of different designs were considered, with various permutations of 8" and 12" main batteries. The largest of these designs emerged in 1940; a gargantuan 38,700-ton design known as "CA2-D". This design would have carried a whopping dozen 12" guns, mounted in four triple turrets in ABXY configuration, a secondary battery of sixteen 5" rifles, and a propulsion plant running at 212,000 shp pushing the ship to a maximum speed of 33.5 knots. Such a ship would have truly blurred the line between the supercruiser and the fast battleship. Perhaps unsurprisingly, this permutation of the Alaska never left the drawing board - at that point, why not just build a battleship?

Of the six Alaska-class cruisers that were planned, only three were laid down. As a reflection of these ships' intermediate status between the classical heavy cruiser and the battleship, these ships would be named for neither city nor state, but for United States territories. The first two, Alaska and Guam, were completed by the New York Shipbuilding Corporation. Commissioned in 1944, these two ships saw limited service in the Pacific, as the war rapidly drew to a close. By that point, these cruisers had no true raison d'être; the Imperial Japanese Navy had been practically obliterated, and its once-vast fleet of cruisers mostly rested at the bottom of the ocean. The emergence of naval aviation as the primary weapon against ships of any size also almost indubitably highlighted the obsolescence of the super-cruiser concept. The last three ships of the class, Philippines, Puerto Rico, and Samoa, were already delayed due to resource allocation to higher-priority warships; their hulls had not been laid down before they were cancelled in June 1943. Hawaii, already under construction, was not cancelled - she was still on the slipways on V-J Day and launched in November 1945. Several studies were considered briefly in the postwar era - conversion to an aircraft carrier, as a guided missile cruiser, a command ship, and almost a decade later, as a Polaris cruiser, but the spirit of postwar defense expenditure reductions prevailed. Construction officially halted in April of 1947, and the incomplete hull laid unused for until her scrapping in 1960.
