Design and description

Designed by the

The Gueydon class had three

The Gueydons had a main armament that consisted of two 40-caliber 194 mm (7.6 in) guns that were mounted in single gun turrets, one each fore and aft of the superstructure. Their secondary armament comprised eight 45-caliber quick-firing (QF) Canon de 164 mm (6.5 in) Modèle 1893 guns in casemates. For anti-torpedo boat defense, they carried four 45-caliber QF Canon de 100 mm (3.9 in) Modèle 1891 guns on the forecastle deck, as well as ten QF 47 mm (1.9 in) and four QF 37 mm (1.5 in) Hotchkiss guns. They were also armed with two submerged 450-millimetre (17.7 in) torpedo tubes.^[1][2]

The Harvey armor belt of the Gueydon-class cruisers covered most of the ships' hull. The lower strake of armor was generally 150 millimetres (5.9 in) thick, although it reduced to 91 millimetres (3.6 in) forward, 81 millimetres (3.2 in) aft. The curved lower protective deck ranged in thickness from 51 to 56 millimetres (2.0 to 2.2 in). The gun turrets were protected by 160–176-millimetre (6.3–6.9 in) armor and had roofs 23 millimetres (0.9 in) thick.^[1][2]

Construction and career

Gueydon was named in honour of

, supervising patrols in Southern America and in the Caribbean.

In 1923, she was refitted in Brest harbour. In 1926, she was again modified to serve as a gunnery school; she entered this role the following year, replacing the armoured cruiser

in Brest.

In 1941, her hull was used by the Germans (with two old French sloops) to form the basis for a decoy-dummy of the Prinz Eugen.

The hulk of Gueydon was bombed by aircraft from the RAF's

on 13 and 14 August 1944, along with the other hulks at Brest, to prevent them from being used by the Germans as blockships. The wreck was broken up after the end of the war.
