HMS Duke of Wellington was a 131-gun first-rate ship of the line of the Royal Navy. Launched in 1852, she was symptomatic of an era of rapid technological change in the navy, being powered both by sail and steam. First christened HMS Windsor Castle, she was the first of a class of four that represented the ultimate development of the wooden three-decker ship of the line which had been the mainstay capital ship in naval warfare for 200 years. After receiving screw propulsion during her construction the ship was launched on 14 September 1852. On that day the Duke of Wellington died, and she was subsequently re-named in his honour and provided with a new figurehead in the image of the duke. When completed on 4 February 1853, HMS Duke of Wellington was, on paper at least, the most powerful warship in the world (and would remain so until the completion of the French Bretagne in 1855) and the largest yet built for the Royal Navy, twice the size of Nelson's HMS Victory and with a far bigger broadside. She was 240 feet (73.1 m) long, displaced 5,892 tons, and carried 131 cannon, weighing a total of 382 tons and mainly firing 32 lb balls.
