13 March 2015, Germany's Deutschland class heavy cruisers, Panzerschiffe (armored ships)
In the early 1920s the Germans were needing to replace some of their pre-World War I battleships but due to the restrictions in the Treat of Versailles they couldn't be over 10,000 tons.
Trying to meet those restrictions was difficult but by creating the "pocket battleship" they created a warship that almost had the punch of a battleship, decent armor, and good speed. Traits which would make the Deutschland class very excellent at long range merchant ship hunters.
