Ship project history


Classical British screw ships-of-the-line, laid down as sail ships, re-ordered as steam-powered and converted to steam power on the stocks. Conversion included lengthening of the hull. Designed armament as sailing ships consisted of 30 x 1 - 204/13 SBML 68pdr 65cwt shell, 30 x 1 - 163/18 SBML 32pdr 56cwt, 40 x 1 - 161/15 SBML 32pdr 42cwt, 14 x 1 - 160/11 SBML 32pdr 25cwt, 4 x 1 - 84/11 18pdr 10-cwt carronades. They presented 2nd group of Modified Queen class. After conversion to steam were rated as 131-gun ships. Wooden hull.

Royal Sovereign became the first RN turret ship to see service. Conversion to armoured turret ship was begun in April 1862. The hull was cut down to the lower deck, giving 2.1-2.4m freeboard. Hull construction was strengthened by additional wood and iron. Turrets were mounted on the main deck with armoured section projecting through the upper deck. No2 (twin) turret was mounted abaft the foremast. Twin turret weighed 163t, singles 151t each, all were hand-worked.

Royal Sovereign was officially rated as coast defence ship, but her draught was rather excessive for this task. She was a good seaboat but had a quick roll.

Ship protection after modernization


There was full length belt armour from the upper deck below wl, 140mm amidships reducing to 114mm fore and aft, armour was laid on 914mm oak plating. Turrets had 140mm walls reinforced with additional 114mm plates in way of gun ports. 1.1m iron bulwarks were fitted around the upper deck for seaworthiness increasing.

Modernizations


(4/1862-8/1864, Portsmouth DYd), Royal Sovereign: was rebuilt as given in the table.
