Ruggiero di Lauria

A fast battlecruiser armed with eight 457 mm guns. The project is based on ideas introduced in 1921 by Italian naval engineer Ferdinando Cassone. In addition to its remarkable armament and displacement, both quite advanced for that era, the project stood out for its innovative anti-torpedo defense system and two-tiered power plant.
