Then there's a second layer of internal armour, 40 mm at 27° construction angle, and behind that, an additional 40 mm at 0°.

Description
The Dunkerque-class, Dunkerque, 1939 is a rank VI French battleship with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update "Firebirds".
General info
Survivability and armour
Dunkerque is a relatively interesting design, as far as survivability goes. On paper, her armour scheme is very capable, with fascinating multi-layered design: First the external skin of 25 mm structural steel (which provides marginal protection) covers the armour of 225 mm at -11 to -13° construction angle (that inverse angle makes armor extra-effective against plunging fire, further increasing the impact angle). Then there's a second layer of internal armour, 40 mm at 27° construction angle, and behind that, an additional 40 mm at 0°. Inside the vessel, along most of the length of the hull, there's an additional fuel tank further separated with 25 mm structural steel from the magazines and engines. Decks are protected split in 3 sections: Aft deck has a single layer of 150 - 100 mm. Armour below the main superstructure is 22 - 20 mm top layer, then 115 mm main deck and 40 mm final layer. Main magazines are protected by 125 mm with 40 mm below it.
This complex protection, however, creates an illusion of safety.
In reality, an number of shells can damage magazines with shrapnel going through the bottom deck. Additionally, barbette of the front primary gun turret decreases to 50 mm, making any shell able to penetrate two plates of 220 mm and 50 mm capable of spraying front magazines with shrapnel. Plunging fire is also dangerous, while armor scheme makes it pretty much impossible for cruisers to penetrate it, the battleships armed with AP shells can have a lucky shell dive right into the magazines.
Finally, the front armour of just 210 mm is a very attractive target for multiple vessels, including some of the heavy cruisers, being able to penetrate it with the AP shells, under a favourable conditions, making it challenging to use Dunkerque in a pursuit role.
Mobility
For a battleship, Dunkerque is relatively mobile, having good speed in a straight line, acceptable turn rate and a well protected bridge and steering gear, making it more likely for her to maintain high mobility under enemy fire. That said, this mobility is limited by her large size, in effect, making it essential to plan two steps ahead especially when it comes to evading enemy torpedoes.

Armament
Primary armament
Dunkerque has one of the most unique primary armaments among battleships in the game, being armed with two turrets of 330 mm. The turrets are protected by 310 mm cemented armour over barbettes and a further 330 mm turret face at a 22° construction angle, making them unlikely to stop most of the battleship-grade AP shells, but they are relatively safe from SAP rounds or vessels armed with lower-calibre guns. The guns have an internal bulkhead modelled between each of the pairs of guns, but each Main Calibre Turret behaves as a single unit within the damage model, so even if only one pair of the Main Calibre Guns is damaged, all of them on the turret will be unable to fire.
The gun comes with two types of shells:
- SAPCBC - Despite being named "330 mm OPF", 330 mm Obus Perforant, or Armour Piercing, the shells are modelled as SAPCBC due to their unusually high percentage of explosive filler. This, in the calculation method used for War Thunder's naval mode, gives them 540 mm penetration at 0° at 1000 m, which in effect means that the guns are unfit to deal with the top-tier battleships Dunkerque will commonly encounter in battles. That said, the large explosive filler, high muzzle velocity, and average spread make them perfectly capable of dealing with lower BR battleships and heavy cruisers with ease.
- HE - With an impressive filler, equivalent to 66 kg, or over triple that of SAP, the high-explosive rounds are able to easily overwhelm any soft target, with even a single shell being capable of inflicting a crippling amount of damage. With an average of over 1 tonne of TNT fired every minute, Dunkerque's sustained TNT equivalent on target is comparable to IJN Mutsu or USS Tennessee, making her relatively efficient at stripping the crew off exposed positions and initiating fires.

Secondary armament
Quite unusually, the secondary armament is split into two types of 130 mm turrets - an aft cluster of three quad-gun turrets and an additional set of twin-gun turrets on each side of the main superstructure. Sharing very good firing angles and an unusually high rate of fire for the secondaries on a battleship, these guns are effective counters to torpedo boats and destroyers alike. With the secondaries being able to easily fire five times for each full reload cycle of the main guns, it is possible to effectively use them in manual control, ensuring maximum accuracy and the ability to deal with multiple targets simultaneously.

Anti-aircraft armament
An important part of the ship's armament responsible for air defence. Anti-aircraft armament is defined by the weapon chosen with the control Select anti-aircraft weapons. Talk about the ship's anti-air cannons and machine guns, the number of guns and their positions, their effective range, and about their overall effectiveness – including against surface targets. If there are no anti-aircraft armaments, remove this section.

Usage in battles
Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).
Pros and cons
Pros:
- Excellent firing angles for both primary and secondary weapons
- Very high sustained TNT equivalent per minute for the HE and SAP shells (if they manage to penetrate the target)
- Multiple redundant fire directors along with a well-protected bridge and steering gear
Cons:
- Main gun magazines are prone to exploding
- Penetrating a turret will cut down the firepower by half
- Inadequate penetration of the SAP shells and no dedicated AP rounds
- No radar or HE-VT shells, along with very poor 37 mm autocannons and a small number of low-calibre guns, resulting in relatively poor anti-air armament
- Very large vessel makes for an attractive target to surface vessels and bombers alike
History
Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
