HMS Barracouta was the last paddle sloop constructed for the Royal Navy, representing a unique and historically significant vessel. Built at Pembroke Dockyard with her keel laid in May 1849, she was launched on 31 March 1851 at a total cost of £50,042. As a second-class paddle sloop, she featured a barque rig and was designed specifically to serve in various maritime theatres. Her construction was singular, being the only ship of her design. Powered by a two-cylinder direct-acting steam engine supplied by Miller, Ravenhill & Salkeld, Barracouta produced approximately 881 indicated horsepower, enabling her to operate effectively alongside her sail rig. She was armed initially with two 10-inch pivot guns and four 32-pounder guns, with her armament undergoing significant updates throughout her service: in 1856, a 68-pounder gun replaced one of the 10-inch guns, and the 32-pounders were upgraded to 42 cwt versions. By 1862, her armament further evolved with the replacement of the 68-pounder by an Armstrong 110-pounder breech-loading rifle. Commissioned in July 1853, HMS Barracouta saw active service in key conflicts of her era. She participated in the Crimean War, notably in the siege of Petropavlovsk, and was involved in the Second Opium War in 1856. Her early service included a noteworthy visit to Nagasaki, where she was part of a squadron led by Vice Admiral Sir James Stirling, tasked with preventing Russian ships from threatening allied interests in Japanese ports. Her operational history also included deployments to North America and West Indies stations, service on the Cape of Good Hope Station during the Anglo-Ashanti wars, and later duties on the Australia Station. During her time in Samoa in 1876, she was involved in the Battle of Mulinu'u, where sailors from Barracouta engaged in a skirmish that resulted in casualties on both sides and the taking of hostages, including an American Colonel. After her final service on the Australia Station, Barracouta returned to England, was paid off in 1877, and was subsequently broken up at Chatham in December 1881. Her career highlights her as a significant vessel bridging the transition from sail to steam in the Royal Navy, and her diverse operational record underscores her maritime importance during mid-19th-century British naval history.
