HMS Frederick William was an 86-gun screw-propelled second-rate ship of the line constructed for the Royal Navy during the 1850s. Originally ordered in 1833 as a 110-gun first-rate vessel named HMS Royal Sovereign, her construction experienced significant delays and was often suspended, beginning only in 1841. She was initially designed as a sail-only ship, measuring approximately 204 feet at the gun deck with a beam of 60 feet and a depth of hold of 23 feet 9 inches, with a tonnage of around 3,099 tons burthen. Her armament was planned to include 110 muzzle-loading smoothbore guns, including 32-pounders and 8-inch shell guns, distributed across her three gun decks. In 1857, reflecting the evolving naval technology and tactics following the Crimean War, the ship was ordered to be razeed and converted into a steam-powered vessel. The conversion began in 1859, during which her hull was lengthened by 10 feet, and her rear section was rejoined with a new midsection, increasing her length to about 214 feet at the gun deck and boosting her displacement to approximately 4,502 long tons. She was fitted with a horizontal two-cylinder steam engine rated at 500 nominal horsepower, supplied by four fire-tube boilers, capable of reaching speeds of nearly 12 knots. Her armament was modernized to include 8-inch shell guns and 32-pounder guns on her gun decks. Launched on 24 March 1860 and completed by June of that year, HMS Frederick William was commissioned as a guard ship, initially at Portland and later at Queenstown, Ireland. She served in this role until 1868, after which she was placed in ordinary. Renamed HMS Worcester in 1876, she transitioned into a training ship for merchant seamen at Greenhithe, serving in this capacity until her sale for scrap in 1948. Subsequently, she foundered in the River Thames shortly after her sale, was raised in 1953, and was broken up. Her service history underscores her adaptation from a traditional line-of-battle ship to a steam-powered vessel, reflecting the significant technological transition in naval warfare during the 19th century.
