Why Dunkerque was not a pocket battleship

Was the Dunkerque class better described as a pocket battleship or a battlecruiser?

Neither label is satisfactory; Dunkerque was a full fast battleship, with capital-ship displacement, endurance, and speed.

The classification follows scale and capability rather than the newspaper label applied to smaller Deutschland-class ships. Dunkerque's deep-load displacement, extensive stores, and ability to steam nearly 8,000 nautical miles at 15 knots all exceed that idea. She could also sustain high-speed movement and reach about 31 knots. Those characteristics place the class firmly among fast battleships, even if its protection and armament reflected French compromises.
