Similar to what Germany employed to circumvent the tonnage restrictions imposed especially upon them by the 1926 bilateral arms ‘agreement”.
This brought you the so-called ‘Pocket Battleship” the Bismarck, among others.
They sacrificed armour for speed. But guns are faster than ships and it took a pounding and sank.
Bismarck wasn’t a “pocket battleship. Just the opposite, it was a full-sized battleship with increased armor protection. Germany had disgarded the restrictions by the time Bismarck was launched. German warship theory was heavier armor and smaller, more accurate guns. Had they been able to produce sufficient numbers of ships, this might have worked. Bismarck wasn’t sunk by the British which reall pissed them off to this day. She was pounded into a useless hulk, but still floated until her own crew scuttled her. The Brits got their revenge for Bismarck sinking the Hood by leaving over 1,000 German survivors to drown. Fair play and all that, eh, chaps? Naturally, they have a different version.
The Kriegsmarine’s three Panzerschiffen, or pocket battleships, were the “Graf Spee”, “Deutschland””, and “Admiral Scheer”.
The “Bismarck” and her sister “Tirpitz” were two of the largest capital ships ever built, in excess of 55,000 tons.
