Main Battery

  • five double 340mm 45cal guns, arranged on the centreline

An American observer was impressed that a single man could train the turret, as opposed to six to eight men needed in American ships.[2]

Secondary Battery

  • twenty-two 138mm 55cal guns in casemates

Other Guns

  • four 47mm guns

Torpedoes

Fire Control

Rangefinders

The Americans reported use of 15 foot Barr & Stroud rangefinders in triplex mountings.[2]

Gunnery Control

The ships used a "cascade system", where the Post Centrale transmitted only to elevated fore and aft turrets, who then relayed the data to the neighboring, lower turrets. In the event that the P.C. failed to send data, the receiving turrets would function as their own mini-P.Cs. and send their data to the lower turrets.[2]

Control Positions

Control Groups

Directors

The ships had no director firing until after World War I.
