This class ship saw the introduction of the 12 inch gun to German battlecruisers which along with the superior layout more than compensated for the reduction in guns carried when compared with their predecessors. Along with the similar Hindenburg they were the only German capital ships with flush decks and were considered excellent sea boats although the casemates were wet and they suffered from having tandem rudders. Crew 44 officers and 1068 men.

|SMS Derfflinger with the heavy tripod mast that replaced the original pole mast after the Battle of Jutland and along with her near sister Hindenburg were the only German battlecruiser fitted with them, Lützow being sunk before the modification could be made. The class are regarded as many people as the best battlecruisers of World War 1 with good protection and speed and adequate firepower.||
