The SMS Derfflinger was a German battlecruiser launched in 1913 as the leader of a class of new battlecruisers that would improve firepower, protection and operational range in respect of previous German battleships. Comparatively they were more armored than their British counterparts. The ships of the Derfflinger class resulted some one of the most brilliant warships on service in their time, achieving great results in offensive actions during the First World War; because of their toughness they were referred as "the iron dogs" by the British.

The ships of the Derfflinger class suppossed an important improvement over the previous Seydlitz class. They had armament of larger caliber entirely placed in the centerline, in a wider hull of flush deck which however was gently raised from stern to prow to achieve a seaworthy hull with the less weight possible. The main belt was thicker and the internal subdivision was even better. The ships of the Derfflinger class were able to absorb a great amount of damage. Whereas the Seydlitz was surpassed by the Lion, the Derfflinger was considered to be equivalent to the Tiger, the successor of the Lion with improved artillery and protection.

The SMS Derfflinger in particular was responsible of sinking two British battlecruisers during the Battle of Jutland, the HMS Queen Mary and the HMS Invincible, albeit assisted, respectively, by the battlecruisers SMS Seydlitz and SMS Lutzow. This one was later scuttled after the battle because of the severe damages received. Finally, following the German armistice, the other two ships of the class were interned in Scapa Flow together with the rest of the German High Seas Fleet and, following the undeserved fate of the rest of the seized ships, they were eventually sunk in 1919 by their own crews as an act of rebellion.
