Dunkerque can best be described as a ship that excels in downtiers but struggles significantly in uptiers. While she may be an exciting vessel to unlock, being the ultimate French ship in the game at the time of her release, it is important to moderate expectations. Like all other vessels at BR 6.7, she finds herself in a challenging position, where many top-tier ships can penetrate her magazines, while she cannot retaliate effectively.

Dunkerque's history was not filled with epic victories in combat or spectacular achievements; nonetheless, she participated in two major historic events that changed the balance of power in the Mediterranean, making her an important vessel from an historical perspective, even if she did not sink any hostile vessels in anger.

A mortar is a type of smoothbore cannon that exclusively uses high-angle plunging fire. It is designed for indirect fire, with projectiles, technically known as bombs, that drop onto targets from above. Mortars are typically smaller, lighter weapon systems with a shorter range compared to other cannons.

18-inch Mk.7 was an American lightweight torpedo developed by Bliss-Leavitt in 1911 as the first American torpedo used on submarines and surface vessels alike. By 1917 an airborne Mk.7 Type D variant was developed, but it has never seen serial production. Mk. 7 remained in service until the end of the World War 2, primarily on the O-type submarines.

While hydroplanes were present in War Thunder prior to Update "Winged Lions", all were standalone aircraft present in the tech tree that could be piloted in air battles by the player. Shipboard reconnaissance aircraft allow large bluewater ships to utilize their plane catapults to send scout planes to perform reconnaissance of an area, land on capture zones, and pester enemy ships with their onboard weaponry.
