HMS Dee, launched on 5 April 1832 from Woolwich Dockyard, was a pioneering paddle steamer in the Royal Navy, notable for being the first of its kind ordered to carry substantial armament. Designed by Sir Robert Seppings and modified by Oliver Lang, Dee's construction featured a length of approximately 166 feet 7 inches on her gundeck, a beam of around 30 feet 4.5 inches, and a depth of hold of 16 feet 4 inches. Her builder's measure was 704 tons, with a displacement of 907 tons. The vessel was powered by a vertical single expansion (VSE) side lever steam engine supplied by Maudslay, Son and Field, driving two 20-foot paddle wheels. She was equipped with two rectangular fire-tube boilers producing steam at 3.5 psi. Her engines, rated at 200 nominal horsepower initially, propelled her at a maximum speed of about 8 knots when the paddle wheels turned at 18 revolutions per minute. In 1866, her engine was upgraded to a 220 nominal horsepower model, reflecting her evolving role. Dee’s machinery is notable enough to have a model preserved at the Science Museum, London. Initially armed with two 18-pounder 22 cwt MLSB guns, her armament was soon increased to six 32-pounder MLSB guns, with a mix of 63 cwt and 56 cwt guns, later replaced by a single 10-inch shell gun. Her armament was removed when she was converted into a storeship in 1868. Dee’s service history includes her initial commission in June 1832 under Commander Robert Oliver, participating in the blockade of Dutch ports during the Belgian Revolution, where her speed and agility proved advantageous in narrow estuaries. She served on various stations, including North America and the West Indies, before being reassigned as a troop transport and later a storeship. Throughout her career, she played roles in relief efforts during the Irish Famine and in maintaining British naval presence at the Cape of Good Hope. Decommissioned and paid off multiple times, HMS Dee was ultimately broken at Sheerness in October 1871, marking the end of her significant service as a trailblazing steam-powered warship.
