German armoured cruisers

SMS Prinz Heinrich was the oldest German armoured cruiser to see service during the First World War.
The two Prinz Adalbert class heavy cruisers were more heavily armed versions of the SMS Prinz Heinrich, herself the oldest German armoured cruiser to see service in the First World War.
The two Roon class heavy cruisers were virtual repeats of the previous Prinz Adalbert, with a slight increase in displacement, 1,500ihp more power and two extra 88mm guns.
The two ships of the Scharnhorst class were the best known German armoured cruisers of the First World War.
SMS Blücher was the first German armoured cruiser built after HMS Dreadnought had revolutionised naval construction. She was a dramatic improvement on previous German armoured cruisers, and closely resembled a stretched version of the first German dreadnoughts (the Nassau class).
