In short: Built by France in the 1930s to counter German commerce raiders, these fast battleships featured a unique, forward-concentrated armament. Despite their innovative design and heavy armour, their careers were cut short by the chaos of World War II, culminating in the scuttling of the fleet at Toulon in 1942.

The Dunkerque class, comprising Dunkerque and Strasbourg, emerged from the constraints of the Washington Naval Treaty. Initially, French naval planners sought small, fast capital ships to counter Italian heavy cruisers. However, the appearance of the German Deutschland-class cruisers shifted priorities, necessitating a vessel capable of resisting 283 mm fire. By 1932, the final design featured eight 330 mm guns mounted in two quadruple turrets forward, a configuration inspired by the British Nelson class to optimize armour weight. Strasbourg, the second ship, received slightly heavier protection to counter the emerging Italian Littorio-class battleships.

Technologically, the ships were pioneers, featuring the first dual-purpose secondary batteries in the French Navy and sophisticated, albeit unreliable, fire-control directors. Their propulsion system utilized a unit machinery arrangement, splitting boilers and turbines into separate systems to enhance damage resistance. Protection was based on the all-or-nothing principle, with a layered torpedo bulkhead system that included liquid-filled voids and ébonite mousse to absorb underwater impacts. Despite these advancements, the ships were often classified as battlecruisers due to their relatively light armament and emphasis on speed over total protection compared to other treaty-era battleships.

The ships' operational lives were brief and marked by political instability. After serving with the Atlantic Squadron and performing diplomatic visits, they were tasked with hunting German raiders upon the outbreak of war in 1939. Following the French defeat in 1940, the British attacked the fleet at Mers-el-Kébir to prevent German seizure, damaging Dunkerque. Strasbourg escaped to Toulon, where she served as a flagship. In November 1942, as Germany launched Case Anton to occupy the remainder of France, the French Navy scuttled both ships to prevent them from falling into enemy hands. Their hulks were later bombed by American aircraft in 1944 and sold for scrap in the 1950s.
