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 Amazon class was a class of six screw sloops of wooden construction built for the Royal Navy between 1865 and 1866.
HMS Surprise was a Vigilant-class gunvessel of the Royal Navy. She was launched at Blackwall Yard, London in 1856 and broken up in Plymouth in 1866.
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.
The Comus class was a class of Royal Navy steam corvettes, re-classified as third-class cruisers in 1888. All were built between 1878 and 1881. The class exemplifies the transitional nature of the late Victorian navy. In design, materials, armament, and propulsion the class members resemble their wooden sailing antecedents, but blended with characteristics of the all-metal mastless steam cruisers which followed.
HMS Sparrowhawk was a Vigilant-class second-class despatch/gunvessel launched on 9 February 1856 at Limehouse, England and served at various stations in the Far East. By the spring of 1865, her rig was a converted to that of a three-masted barque. She was sold in 1872, converted to a sailing barque in mercantile service, and was later a coal lighter in Australia.
HMS Eclipse was a 4-gun Cormorant-class first class gunvessel launched in 1860 from the shipyard of J. Scott Russell & Co., Millwall. She served on the Australia Station, took part in the Second Taranaki War, including contributing men to a naval brigade which attacked the Maori stronghold at Gate Pā. The entire class were never satisfactory as gunvessels, partly due to their excessive draught, and Eclipse was broken up at Sheerness in 1867, only 7 years after her launch.
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 Myrmidon was a Cormorant-class gunvessel of the Royal Navy, built at Chatham Dockyard and launched in 1867. She served on the North America and West Indies Station and surveyed parts of the Australian coast before being sold at Hong Kong in 1889.
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 Ariel-class gunboat was a class of nine 4-gun composite gunboats built for the Royal Navy between 1871 and 1873. Although most were sold by 1890, one of them survived into the 1920s as a salvage vessel in private ownership. They were the first class of Royal Navy gunboat built of composite construction, that is, with iron keel, stem and stern posts, and iron framing, but planked with wood.
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.
HMS Arab was an Arab-class composite gunvessel built for the Royal Navy in 1874. She served in the East Indies and was sold in 1889.
HMS Lily was an Arab-class composite gunvessel built for the Royal Navy. She was launched in 1874, saw service in Chinese and North American waters, and was wrecked on the coast of Labrador on 16 September 1888.
The Britomart-class gunboat was a class of sixteen gunboats built for the Royal Navy in 1859–1867.
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 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.
