French cruiser Gueydon

Designed by the naval architect Emile Bertin, the Gueydon-class ships were intended to fill the commerce-raiding strategy of the Jeune École.

Steam for Gueydon's engines was provided by 28 Niclausse boilers and they were rated at a total of 20,000 metric horsepower (15,000 kW) that gave them a speed of 21 knots (39 km/h; 24 mph).

The ships could carry enough coal to steam for 8,500 nautical miles (15,700 km; 9,800 mi) at a speed of 10 knots (19 km/h; 12 mph).

Their secondary armament comprised eight 45-caliber quick-firing (QF) Canon de 164 mm (6.5 in) Modèle 1893 guns in casemates.

In 1926, she was again modified to serve as a gunnery school; she entered this role the following year, replacing the armoured cruiser Pothuau in Brest.
