The design incorporated a radical arrangement for the twelve 340 mm (13.4 in) main battery guns: three quadruple-gun turrets, the first of their kind, as opposed to the twin-gun turrets used by most other navies. The first four ships were also equipped with an unusual hybrid propulsion system that used both steam turbines and triple-expansion steam engines to increase fuel efficiency.
