SMS Derfflinger - the lead vessel of her class of 3 battlecruisers in the German Navy. Nicknamed the
"Iron Dog" as a sign of respect by the British
, she was the lead ship in "The Death Ride of the Battlecruisers" at the Battle of Jutland.
In contrast to British battlecruisers, the German battlecruisers were much more heavily armored and had more watertight subdivisions, allowing them to take vastly more punishment than their counterparts in the Royal Navy. Their main guns were generally smaller than their British counterparts with the extra weight being used for armor, however their secondary armament was much heavier (5.9" secondaries vs 4" on the British ships) so at medium ranges the German ships were able to inflict substantial damage.
At Jutland as part of Admiral Hipper's 1st Scouting Group, the
Derfflinger was responsible in part for the sinking of 2 British battlecruisers at Jutland (
Queen Mary and
Invincible). When trapped, Admiral Scheer ordered the 4 remaining battlecruisers to attack headfirst into the 24 battleships of the British Grand Fleet to cover the escape of the German High Seas fleet - amazing that the
Derfflinger survived despite being hit by 17 heavy caliber shells.

Couple of great videos about the Battle of Jutland - the lack of following regulations concerning the stowing of ammunition and propellant should be required watching for everyone.
