HMS Amphion was a 36-gun wooden-hulled screw frigate of the Royal Navy, representing an important transition in naval technology during the mid-19th century. Originally ordered as a sail-powered ship from Woolwich Dockyard and initially named HMS Ambuscade, she was renamed in 1831 and laid down in 1840. However, her design was later modified, and she was reordered in 1844 as a prototype screw frigate based on a design by White, reflecting the navy's shift toward steam propulsion. Launched on 14 January 1846 and commissioned on 13 May 1847, HMS Amphion was powered by machinery supplied by Miller, Ravenhill & Co, designed by John Ericsson. The installation of her steam engines at the East India Docks marked a significant technological upgrade, although it restricted her internal space for provisions and munitions due to the machinery's size. The hull construction cost £36,115, with an additional £16,673 spent on machinery and £22,794 on fitting her for sea, completed at Sheerness. Initially armed with 36 guns, Amphion was reduced to 30 guns in 1848 but later restored to her full armament in 1856. Her service included deployment during the Crimean War, notably in the Baltic Sea, where she participated in naval operations. A notable incident occurred in June 1855 when she ran aground at Sveaborg in the Grand Duchy of Finland; during this event, she was fired upon by Russian artillery, resulting in the death of one crew member and injuries to two others. HMS Amphion's career concluded when she was sold to William Williams on 12 October 1863 for breaking up. Her service and technological features exemplify the transitional period in naval architecture, bridging traditional sailing ships and the advent of steam-powered warships.
