HMS Swinger was an Ariel-class composite gunboat of the Royal Navy, launched on 7 February 1872 at Pembroke Dockyard. Designed by Sir Edward Reed, the Chief Constructor of the Royal Navy, she represented the first class of gunboats built with composite construction, combining iron frames with wooden planking. The vessel was powered by a horizontal single-expansion steam engine supplied by Humphrys, Tennant & Co., which produced 461 indicated horsepower—an engine type differing from the compound-expansion engines used in other ships of her class. The ship's armament initially included two 6-inch (150 mm) 64-pounder muzzle-loading rifles and two 4-inch (100 mm) 20-pounder Armstrong breech loaders, all mounted on traversing carriages, allowing for flexible firing arcs. The entire class was rigged with a three-masted barquentine, providing sailing capability alongside steam power. Commissioned for service on the China Station, Swinger was re-commissioned at Hong Kong in 1877, reflecting Royal Navy policy of deploying entire crews to distant stations. In 1883, she was commissioned at Devonport and assigned to the Australia Station, arriving in Australia in 1884 under Lieutenant Marx. During her service, Swinger was actively involved in anti-slavery efforts, notably intervening in the blackbirding trade. Her crew played a key role in the rescue of 18 islanders thrown overboard by the crew of the suspicious vessel Forest King, after discovering illegal enslavement. The subsequent court proceedings vindicated Lieutenant Marx and highlighted Swinger's role in enforcing anti-slavery laws. In 1886, Swinger was involved in an incident where Lieutenant Marx was attacked while ashore in New Guinea, illustrating the dangers faced during her patrols. The vessel was re-commissioned in Sydney in 1887 and remained on the Australia Station until 1891. She was hulked in 1895, ending her active service. During World War I, Swinger was attached to HMS Impregnable as a store ship. She was ultimately sold for breaking in 1924, marking the end of her maritime career.
