The Beacon-class gunvessels were a class of composite gunboats built for the Royal Navy in the late 1860s. They were the first warships of the Royal Navy expressly designed to use the engines of an older class of ships with a different hull shape. They were generally deployed overseas to the China, East Indies, West Africa, Pacific, North America and West Indies Stations. In addition to showing the flag, the ships fought pirates and suppressed the slave trade in East and West Africa. As their engines wore out in the mid-1880s, they were mostly retired and scrapped by the end of the decade. A few survived into the early 1900s as they were modified for harbour service before being sold or scrapped.
