HMS Basilisk was a first-class paddle sloop of the Royal Navy, launched on 22 August 1848 from Woolwich Dockyard. Designed by Oliver Lang, she was constructed following the same lines as her sister ship, the screw sloop Niger, though Basilisk was fitted with paddlewheels driven by a Miller, Ravenhill & Salkeld two-cylinder oscillating steam engine rated at 400 nominal horsepower and producing approximately 1,033 indicated horsepower (770 kW). Her armament included a single 68-pounder smoothbore muzzle-loading gun on a pivot, a 10-inch shell gun, and four 32-pounder smoothbore muzzle-loading guns on truck mountings. Basilisk’s early significance lay in her role in the 1849 comparative trials with the screw sloop Niger in the English Channel. These trials demonstrated the superiority of screw propulsion over paddle wheels, as both ships had similar design and power, confirming the technological shift in naval engineering. In her service history, Basilisk participated notably in the Crimean War (1854–1855), operating in the Baltic Sea. She took part in the blockade of Courland, sinking ten Russian transports carrying grain on 14 June 1855, and also sank salt boats on 13 July. Additionally, she engaged Russian gunboats and shore batteries during the action of 17 July in the Gulf of Riga. Throughout her career, Basilisk served on various stations, including North America and West Indies, China, and Japan. In 1868, she was driven ashore on the coast of China, incurring repairs costing £1,777. From March 1871, under Captain John Moresby, she served on the Australia Station, conducting hydrographic surveys around New Guinea. During these surveys, she discovered the harbor now known as Port Moresby, the capital of Papua New Guinea. She also participated in anti-blackbirding operations in the South Pacific and visited the Ellice Islands in July 1872. Basilisk was decommissioned and broken up at Chatham in 1882, ending a distinguished service that included technological trials, wartime action, and crucial exploration and survey work in the Pacific.
