Ship project history: First large ships built in France after First World War, built under the 1922 program. They became first-ever light cruisers with artillery placed in superfiring closed turrets. Practically had no serious armour protection. Partly its absence was indemnified by a double bottom and presence of 16 transverse bulkheads. Differed by strong torpedo armament.

On trials all reached designed speed at full load. Differed by good seaworthiness, to lacks it is possible to refer short endurance, especially on the high speed.

Ship protection: Magazines and steering gear had box-shaped 20mm protection. There was no belt.
