Player Opinion


Puerto Rico is a Tier X American reward cruiser, available through the Dockyard feature introduced in the 2019 Christmas Event.

Over her lower tier'ed relative, Alaska, Puerto Rico offers slightly improved protection and a fourth main gun turret, as well as superior Anti-Air protection. She does however come with her weaknesses.

Main firepower wise Puerto Rico offers the heaviest broadside available to any cruiser in World of Warships. Captains who are used to Alaska will feel at home with the handling of these weapons, but will also find that Puerto Rico's accuracy leaves something to be desired. It is noticably worse than that of Alaska, leading to dispersion trolling the player at times. Puerto Rico is better than average for tier X, but still inferior to battleships, making the usage of Gun Fire Control System Modification 2 (Extends the firing range of the main battery: +16% firing range.) highly recommended (but not required).

Puerto Rico's resilience against incoming damage is decent for a super-cruiser. She sports a high health pool, right in between Kronshtadt and Stalingrad, while also having a reinforced midsection. Her case-mate deck is 38mm thick, which is enough to shatter a lot of HE rounds as well as being capable of auto-bouncing any AP shell in the game. It should be noted however that the upper belt, which connects the 254mm main belt with the 38mm upper deck, is only 30mm thick, meaning that lucky shells with a caliber of 431mm+ like from Republique, Yamato and Georgia can still over-match through that strip and deal normal penetration damage. Like the other super-cruisers, Puerto Rico burns for the full duration of 60s before modifiers are added, making her vulnerable against fire damage. Usage of survivability-enhancing captain skills such as Fire Prevention and modules such as Damage Control System Modification 2 (Accelerates fire extinguishing and recovery from flooding: -15% flooding recovery time. / -15% fire duration.) is advised.

Against aircraft Puerto Rico offers a strong AA-suite, further enhanced by the Defensive AA Fire (While active, the damage per second of large caliber anti-aircraft guns is increased.) consumable. However, by itself her AA is average for her tier and doesn't grant immunity against skilled carrier players, and her large size and sluggish performance will make dodging incoming ordinance difficult.

Play-style wise Puerto Rico should be played like an active, kiting cruiser. Using her speed to gain access to ship's sides to capitalize on the heavy AP broadside. If no such shot is possible, the player should resort to using HE shells to deal damage against angled cruisers or battleships, while seeking another opportunity to flank the enemy (though plunging AP can still score the occasional good hit). While Puerto Rico has access to the Surveillance Radar (While active, detects all enemy ships within the specified radius, disregarding obstacles such as smoke and terrain.) consumable, it is not recommended to actively push in the first half of the match as disengaging in a pinch will be nearly impossible, and a trip back to port immanent. For a similar reason it is not recommended to play her like a bow-tanking ship, similar to Stalingrad, as the balanced gun layout and the lack of heavy case-mate protection will result in less than ideal performance.

It should be noted that Puerto Rico can be played close-in (not recommended), as a camper (lower muzzle velocity), or as a long-distance kiter as mentioned above (preferred). This presents many different options for build-out, and captains should consider carefully which tools will be most useful based on play-style.


  • Huge health pool for a cruiser
  • Twelve 305mm rifles give great alpha damage potential and have better than average range for her tier
  • Good turret traverse
  • Decent fire-starting potential with HE
  • Many consumable options, including radar


  • Due to her size, not agile
  • Battleship dispersion and slow reload, coupled with average dispersion
  • Lousy base concealment
  • Vulnerable to broadside damage if not careful


As a special ship, Puerto Rico doesn't have any upgrades to research.

Optimal Configuration

Commander Skills


Puerto Rico can equip the following consumables:


As a premium ship, Puerto Rico comes included with Type 20 permanent camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her service cost by 50%, and increases her earned CreditsCredits by 20% and Experience by 100%.
