In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
HMS Algerine was a Phoenix-class steel screw sloop of the Royal Navy. She was launched at Devonport in 1895, saw action in China during the Boxer Rebellion, and later served on the Pacific Station. She was stripped of her crew at Esquimalt in 1914, and transferred to the Royal Canadian Navy in 1917, being commissioned as HMCS Algerine. She was sold as a salvage vessel in 1919 and wrecked in 1923.
HMS Shearwater was a Condor-class sloop launched in 1900. She served on the Pacific Station and in 1915 was transferred to the Royal Canadian Navy as HMCS Shearwater, serving as a submarine depot ship until 1919. She was sold to the Western Shipping Company in May 1922 and renamed Vedas.
Seven ships of the Royal Navy have borne the name HMS Rosario, after the Spanish word Rosario, meaning rosary:
Ten ships of the Royal Navy have borne the name HMS Mutine :
The Beagle class was a two-ship class of 8-gun screw steel sloops built for the Royal Navy in 1889.
The Alert class was a two-ship class of 6-gun screw steel sloops built for the Royal Navy in 1894.
The Phoenix class was a two-ship class of 6-gun screw steel sloops built for the Royal Navy in 1895. Both ships participated in the suppression of the Boxer Rebellion, but Phoenix was destroyed in a typhoon while alongside in Hong Kong in 1906. Algerine became a depot ship at Esquimalt, was sold in 1919, and was finally wrecked in 1923.
HMS Fantome was an Cadmus-class sloop launched in 1901, transferred to the Royal Australian Navy in 1914, returned to the Royal Navy in 1920, and sold in 1924. She was the fourth ship of the Royal Navy to bear the name, which is from the French fantôme, meaning "ghost".
The Cadmus class was a six-ship class of 10-gun screw steel sloops built at Sheerness Dockyard for the Royal Navy between 1900 and 1903. This was the last class of the Victorian Navy's multitude of sloops, gunvessels and gunboats to be constructed, and they followed the traditional pattern for 'colonial' small warships, with a full rig of sails. After them, the "Fisher Reforms" of the Navy ended the construction and deployment of this type of vessel. All of the class survived until the 1920s, remaining on colonial stations during World War I.
The Cruizer class was a class of six 17-gun wooden screw sloops built for the Royal Navy between 1852 and 1856.
The Rosario class was a class of seven screw-sloops of wooden construction built for the Royal Navy between 1860 and 1862. A further six vessels were ordered and laid down, but were cancelled in 1863 before launch. This was the last class of purely wooden sloops built for the Royal Navy.
HMS Hyacinth was an 8-gun Satellite-class composite sloop built for the Royal Navy, launched in 1881 and sold in 1902. She and the rest of her class were re-classified as corvettes in 1884.
HMS Rambler was an Algerine-class gunvessel of the Royal Navy, built by John Elder & Co., Glasgow and launched on 26 January 1880. She was commissioned as a survey vessel in 1884 and served in Chinese waters during the 1880s and 1890s. She provided men to a naval brigade during the Boer War and was sold on 23 January 1907. The work of this vessel is now remembered in Hong Kong by the Rambler Channel near Tsing Yi.
The Greyhound class was a development of the Cruizer-class sloop, and comprised two 17-gun wooden screw sloops. They were both launched in 1859 and saw service with the Royal Navy until 1870. The class was reclassified as corvettes in 1862.
HMS Phoenix was a Royal Navy Phoenix-class steel screw sloop. She was launched at Devonport in 1895, saw action in China during the Boxer Rebellion, and later served on the Pacific Station. She had the misfortune to be alongside a coaling pier in Hong Kong on 18 September 1906 when a typhoon struck the colony. She foundered and became a total loss.
HMS Mutine was a Doterel-class sloop of the Royal Navy, built at the Devonport Dockyard and launched on 20 July 1880. She became a boom defence vessel at Southampton in 1899 and was renamed Azov in 1904. She was sold after World War I.
HMS Mutine was a Condor-class sloop of the Royal Navy. Mutine was launched on 1 March 1900. While being delivered from Birkenhead to Portsmouth an accident in Mutine's boiler rooms caused some loss of life and gave her a name as an unlucky ship before her career even began. She served on the China Station, then the Australia Station between December 1903 and February 1905 and later became a survey ship, surviving until 1932 as a Royal Naval Volunteer Reserve drill ship, the last of her class to be sold.
HMS Cadmus was a Cadmus-class sloop of the Royal Navy. She was launched at Sheerness in 1903, spent her entire career in the Far East and was sold at Hong Kong in 1921.
HMS Titania was a Royal Navy submarine depot ship. Most of those that saw service in the First World War were scrapped in the 1930s. Titania, however, saw service in the Second World War. She was scrapped at Faslane, Scotland, in September 1949.
