If your ignore the exisistance of the Hood, Repluse and RenownYes, "pocket battleship" is the term. It was an ingenious design by German naval architects to essentially get around the tight limitations imposed on German ships in the Treaty of Versailles. That limited Germany to 10,000 tons and no more that 11" guns. The Deutschland class ships (the eponymous, the Admiral Scheer and Graf Spee) were far more heavily armoured than British cruisers and their nine 11" and eight 6" guns gave them a formidable armament. They were faster than British battleships of the time as well. Never seen before; never matched at the time and never seen after. Unique.
All of which totally outmatched these pocket battleships,
