Class. Other ships of this type, modeled on a ship designed by Sané and launched in 1782, were already afloat in 1816. The height of the lower battery was 5ft 10in. The armaments above are those of the earlier sisters Scipion and Marengo and represent the evolution of the class. Duc de Berry, begun as Glorieux, was renamed 8.7.14 and 15.7.15. She was taken to Brest after launch but was not commissioned and became Glorieux again on 9.8.30. Triton, begun as Vénitien, was renamed 29.8.14 and 15.7.15. Her frame was begun at Bayonne 10.05 and was completed by 12.07. Serious work on the ship at Rochefort did not begin until 9.14. Couronne was renamed Barricade 29.2.48 and Duperré 1849.

Disposals. Glorieux ex Duc de Berry became the razeed frigate Minerve (q.v.) on 12.10.31. Jean Bart was BU 1833 at Brest. Triton became a sheer hulk and was BU 1872. Couronne served briefly as a hulk and was BU 1870. Généreux became a barracks hulk for seamen at Toulon and was BU 1865.

LA TOUR D'AUVERGNEBrest------Canc. 1852

Class. Although the 3rd class 90-gun ship was to be the mainstay of the fleet, the French navy wanted to retain a few 4th class ships for use in shallow water or for coastal bombardment during combined expeditions. The old 74s were rapidly disappearing, and the navy planned to build a maximum of four new ones. The data above are from design requirements developed by the Conseil des Travaux on 27.2.50, with an alternative armament requested by the Council of Admiralty on 5.6.50. The hull lines of Sané's 80-gunner were to be followed as closely as possible, and all of the operational characteristics of the old 74s were to be retained except for a reduced supply of water. Space and weight were to be reserved for auxiliary steam machinery of 110-120nhp (later reduced to 80nhp, 110ihp) for 4.5 to 5 kts. The council tentatively approved a plan by Leboulleur de Courlon on 25.6.51, but in approving his modified plan on 21.1.52 it recommended deferring the project until the trials of Charlemagne and Napoléon. The success of these more powerfully engined ships later in 1852 put an end to the idea of a 4th class battleship with weak steam propulsion.
