High Quality Content by WIKIPEDIA articles! The Normandie class of dreadnought battleships was a group of five ships ordered for the French Navy in 1912–1913. The class comprised Normandie, the lead ship, Flandre, Gascogne, Languedoc, and Bearn. The design incorporated a radical arrangement for the twelve 340 mm main battery guns: three quadruple gun turrets, as opposed to the twin turrets used by most other navies. The first four ships were also equipped with an unusual hybrid propulsion system that used both steam turbine and triple expansion engines to increase fuel efficiency.
