Small armored cruiser, successor of the huge Gloire class  heavy protected cruiser.
Increased main gun size and a diminished secundary to quintary battery and a total different armor lay out resulted in a class of ships a lot smaller than the 3 Gloires.

They became the mainstay cruiser of the French marine.  The large class of ships build in different yards at different times following the same plans with yard specific florishes make that the capabilities are the same, but that the ships have their own differences.

Misc weight allocation
25 tons for the underwater torpedo tubes
50 tons crew comfort
25 large marconi
