HMS Congo was the Royal Navy's first steam-powered warship, constructed in 1816 at Deptford Dockyard. Designed by Sir Robert Seppings and ordered on 13 April 1815, the vessel was intended for an exploratory mission along the Congo River. She was launched on 11 January 1816 as a steam sloop, with a notable feature being her steam engine, which weighed approximately 30 tons and was capable of producing 20 horsepower. However, during initial trials, the engine's performance was disappointing; it only propelled the vessel at about three knots when connected to the paddle wheels. Additionally, handling issues earned her the nickname "very crank." Consequently, the engine and paddle wheels were removed before her first voyage, and she was rigged as a schooner for her expedition. The vessel’s primary mission was to explore and map the Congo River, under the command of James Hingston Tuckey. The expedition aimed to chart the river's course and assess navigability. Unfortunately, the expedition was disastrous, with 38 of the 56 members perishing from tropical fever, likely yellow fever, including officers, scientists, and crew members. The expedition demonstrated that the lower Congo River was not navigable beyond 100 miles from the coast, and it highlighted the perils of exploration in tropical climates, especially before advances in medicine. Support vessels, such as the Dorothy, remained at the rapids, with most survivors remaining inland. After her return, HMS Congo was fitted out as a hulk in 1819 and laid up in the Swale. She was eventually sold at Rye on 15 March 1826 to J. Harvey for £146. Her historical significance lies in her status as the first steam-powered warship of the Royal Navy and her role in early African exploration, despite the tragic outcome of her maiden voyage.
