The Osprey class was a Royal Navy class of screw-driven sloops built between 1874 and 1877. Nine additional ships were built to a revised design, the Doterel-class sloop. They were the first class of ship in the Royal Navy to use glass scuttles.
The Algerine-class gunboats were a class of six 3-gun wooden gunboats built for the Royal Navy in 1857. A further pair were built in India for the Bombay Marine in 1859.
HMS Viper was an armoured iron gunboat, the only ship of her class, and the fourteenth ship of the Royal Navy to bear the name.
The Vigilant-class gunvessel of the Royal Navy was an enlarged version of the Arrow-class gunvessel of 1854. Both classes were designed for shallow-water operations in the Baltic and Black Seas during the Crimean War. Fourteen of the class were completed, but were ready too late to take part in that conflict. Cormorant was sunk in action at the Taku Forts, Osprey was wrecked on the coast of Africa in 1867 and the rest were all sold during the 1860s, with Sparrowhawk lasting until 1872.
HMS Wasp was a Banterer-class composite screw gunboat of the Royal Navy, built in 1880 by Barrow Iron Shipbuilding and wrecked off Tory Island in 1884.
The Condor-class gunvessel was a class of four Royal Navy composite gunvessels of 3 guns, built between 1876 and 1877. They were all hulked or sold before 1893, giving them an active life of less than 15 years.
The Doterel class was a Royal Navy class of screw-driven sloops. They were of composite construction, with wooden hulls over an iron frame. They were a revised version of an 1874 design by the Royal Navy's Chief Constructor, William Henry White, the Osprey-class sloop. Two of the class were lost, one to an explosion off Chile and one wrecked off Canada. Gannet is preserved at Chatham Historic Dockyard.
The Philomel-class gunvessel was a class of wooden-hulled screw-driven second-class gunvessels built for the Royal Navy between 1859 and 1867, of which 26 were ordered but only 20 completed. They had a mixed history, with some serving for as little as 5 years, and others surviving into the 1880s. Two of the class were sold and used as Arctic exploration vessels, both eventually being lost in the ice.
HMS Swinger was an Ariel-class composite gunboat of the Royal Navy, built at Pembroke Dockyard and launched on 7 February 1872. She served at first on the China Station and from 1883 on the Australia Station. She was hulked in 1895 sold for breaking in 1924.
HMS Raven was a Banterer-class gunboat of the Royal Navy, built by Samuda Brothers of Poplar, London, and launched on 18 May 1882. She served on the Australia Station and was converted to a diving tender in 1904. After being lent as a training ship in 1913 she was sold for breaking in 1925.
The Algerine-class gunvessel was a class of three Royal Navy composite gunvessels built in 1880. Two of them were sold after only ten years of service, but the other was converted to a survey ship before commissioning and survived in this role until 1907.
Intrepid-class gunvessels were a class of six Royal Navy first-class wooden gunvessels built in 1855-56. They were rated as sloops from 1859 to 1862, and were scrapped by 1865. Victor was sold to the Confederate States of America as the raider CSS Rappahannock, but she was interned by the French at Calais and never fulfilled her intended function.
The Arab-class gunvessels were a pair of composite gunboats built for the Royal Navy in the mid-1870s.
The Banterer-class gunboat was a class of eleven gunboats mounting two 6-inch and two 4-inch guns, built for the Royal Navy between 1880 and 1892.
The Albacore-class gunboat, also known as "Crimean gunboat", was a class of 98 gunboats built for the Royal Navy in 1855 and 1856 for use in the 1853-1856 Crimean War. The design of the class, by W. H. Walker, was approved on 18 April 1855. The first vessels were ordered the same day, and 48 were on order by July; a second batch, which included Surly, were ordered in early October.
The Britomart-class gunboat was a class of sixteen gunboats built for the Royal Navy in 1859–1867.
The Bramble-class gunboat was a class of four gunboats mounting six 4-inch guns, built for the Royal Navy in 1886. In 1887 the first three were reclassified as gunvessels.
The Forester-class gunboat was a class of 4-gun composite gunboats built for the Royal Navy between 1874 and 1877. Although half had been sold by 1890, the rest survived into the 20th century as coal hulks, base vessels and other secondary uses. Foxhound survived as a hulk on the Blackwall Reach of the Thames until 1975, when she was broken up. They were built of composite construction, that is, with iron keel, stem and stern posts, and iron framing, but planked with wood.
The Albacore-class gunboat was a class of three gunboats built for the Royal Navy in 1883. The name had already been used for a class of 98 gunboats built during the Great Armament of the Crimean War.
The Cormorant-class gunvessels were a class of 4-gun first-class gunvessels built for the Royal Navy in the 1860s. They were somewhat unsuccessful; intended for shore bombardment in shallow water, they exceeded their design draft by 50%. Seven of the 13 ships ordered were suspended, with 3 finished or converted as survey ships and the other 4 cancelled. Racehorse was wrecked after only 4 years, and those ships that were completed as planned had short operational lives, in some cases less than 10 years. The survey vessels lasted longest, with the last ship of the class, Sylvia, being broken up in 1890.
