The French carrier-battleship discussion classifies Dunkerque as a fast battleship rather than a battlecruiser. The decisive evidence is not simply the thickness of the heaviest armor. Classification also depends on how much of the hull the armor covers and how extensively the protected volume is subdivided. Those features reveal how a design expects to absorb damage and preserve fighting ability. The comparison provides a practical method for placing ships along the spectrum from lightly protected early battlecruisers to fully protected dreadnought battleships.

Why Dunkerque's protection matters more than the battlecruiser label
Classifying the Dunkerque class requires examining the area protected and the subdivision behind its armor, not merely comparing maximum belt thickness or speed.
