Preceded by the Liberté-class and succeeded by the Courbet-class. Due to the huge number of changes of the original design and lacking decisions of the French minister of navy Gaston Thomson (29 January 1848, Oran, French Algeria-14 May 1932 Bône, Algeria) in time caused a serious delay in realizing the class. General technical specifications of this class. Displacement 18.754 tons/18.458 long tons (normal)-19.763 tons/19.451 long tons (deep load) and as dimensions 145 (on waterline)-146,6cm (over all) x 25,8 x 8,44 metres or 475.9-481.0 x 84.8 x 27.8 feet. The 4 License built Parsons steam turbines and 26 coal-fired Belleville or Niclausse water tube-boilers supplied via 4 shafts 22.500 shp allowing a speed of 19,25 (design)-19,7/20,66 (trials) knots and with a speed of 12 knots and a maximum coal bunker capacity of 2.027 tons/1.995 tons varied the range between 3.120-4.866 nautical miles. The range was nearly the half of the preceded classes caused by the worse economical fuel consumption of the turbines at low speeds.
