| abstract | - A 5,630-ton broadside ironclad, she had a wooden hull. Her 12 cm-thick (4.7 in) armour plates, backed with 43 cm (17 in) of timber, resisted the experimental firing of the strongest guns of the time (the French 50-pounder and the British 68-pounder) at full charge, at a distance of 20 metres (65 ft). Her official top speed was 13.1 knots but other reports suggested no more than 11.75 knots had been reached and that 11 knots was the practical maximum. As was common for the era, La Gloire was constructed with sails as well as a steam-powered screw. The original rigging was a light barquentine rig providing 1,096 sq. m (11,800 sq. ft) of surface area. This was later increased to a full rig providing 2,508 sq. m (27,000 sq. ft) of surface. La Gloire rendered obsolete traditional unarmoured wooden ships-of-the-line, and all major navies had no choice but to build ironclads of their own. However La Gloire was soon herself rendered obsolete by the launching in 1860 of the British HMS Warrior, the world's first iron-hulled warship. In 1879, La Gloire was struck from the French fleet registry and scrapped in 1883.
