The Queen Elizabeth-class battleships were a group of five super-dreadnoughts built for the Royal Navy during the 1910s. These battleships were superior in firepower, protection and speed to their Royal Navy predecessors of the Iron Duke class as well as preceding German classes such as the König class. The corresponding Bayern-class ships were generally considered competitive, although the Queen Elizabeth class were 2 knots (3.7 km/h) faster and outnumbered the German class 5:2. The Queen Elizabeths are generally considered the first fast battleships of their day.
