The Brooklyn class, USS Brooklyn (CL-40) is a rank V American light cruiser with a battle rating of 5.7 (AB/RB/SB). It was introduced in Update 1.87 "Locked On".

General info

Survivability and armour

The Brooklyn is protected by both sheer internal volume and thick armour around vital components. The turrets are easily the most protected in the game, with 165mm of rolled cemented armour on the turret face, 75mm of RHA on the turret sides, and 152mm of antifragmentation armour on the ammo elevators.

Bow ammunition storage is stored below the waterline, and it is protected not only by 51mm of antifragmentation armour but also by a "wrapped" fuel tank that can absorb incoming shells.


Manoeuvrability is what should be expected for a 12,242-ton vessel: sluggish.


Primary armament

  • 15 x 6-inch/47 calibre Mk. 16 guns in five triple turrets. The Brooklyn fires more high explosive per salvo than any other ship in the game and the main guns' rate of fire is bested only by HMS Tiger.

Secondary armament

The Brooklyn has 4 5-inch, 25 calibre guns on either side of the ship. These have roughly the same explosive filler per HE and rate of fire as the 5-inch, 38 calibre guns on the Sumner, Somers, Farragut, and Fletcher. They are effective against both air and surface targets.

Anti-aircraft armament

Main article: AN-M2 (12.7 mm)

8 x .50 calibre AN-M2 machine guns is a paltry close-range anti-aircraft package. An enemy plane using a nearby island to their advantage can often close the distance before your .50 calibre anti-aircraft weapons have time to neutralize a target.

Usage in battles

The Brooklyn is easily the strongest ship in War Thunder. Combining adequate protection with unparalleled firepower, it can hold its own most other cruisers without much threat to itself. If isolated, a Brooklyn can be taken down by a group of cruisers or even destroyers via ammoracking. If, however, the Brooklyn is integrated into a team of CLs, the chance of defeating it becomes far lower.

The main threats to the Brooklyn are the Kirov, Southampton, and Furutaka. It is advised to engage these targets first and other cruisers second; the Kirov and Furutaka have sufficient firepower to threaten a Brooklyn, and the Southampton's armour dampens the firepower advantage of the Brooklyn.

Pros and cons


  • Great broadside firepower for a cruiser
  • Fairly resilient to small-calibre rounds
  • Has one of the best turret protections of every ship in the game.


  • Can't carry torpedoes
  • Very light AA defence (not including the 5-inch guns)
  • Rather slow compared to PT boats
  • Large target overall.


In 1930, the London Naval Treaty extended the limitations imposed by the Washington Naval Treaty by further limiting the construction of large warships. Well-aware of the importance of such warships for operations in the Pacific, the U.S. Navy initiated the development of a new light cruiser design that would suit their needs, whilst remaining within the limitations of both treaties. The new design, that would become the Brooklyn-class light cruisers, was a compromise between heavy cruiser size and protection and light cruiser armament. In other words, the ship would remain within the 10,000-ton displacement limit, but would also offer the desired seaworthiness and autonomy at the same time.

Initially, the ship was intended to carry only a dozen 6-inch main guns. However, with the appearance of the Japanese Mogami-class cruiser, a decision was hastily made to increase the number of main guns to 15, in order to match the armament of the Mogami-class. With this choice, the Brooklyn-class cruisers would become the most heavily armed light cruisers ever built for the USN. The first orders for four ships were issued in 1933, followed by an additional three in 1934. The lead ship of the class, USS Brooklyn (CL-40), was laid down in March 1935 and commissioned into service in September 1937.

USS Brooklyn primarily served in the Mediterranean theatre during WW2, participating in the North African campaign and later on in the Italian campaign. The ship mostly served as a support in landing operations and performed coastline bombardments, while also engaging in the occasional naval skirmish. Soon after the end of WW2, USS Brooklyn was decommissioned in 1947 and handed over to the Chilean Navy in 1951 under the new name of O’Higgins (CL-02). The ship would continue to serve on with the Chilean Navy for over 40 years, before being sold for scraps in 1992.
