Steam frigates and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. There were some exceptions like for example the French Napoléon class steam ship of the line was meant to stand in the line of battle, making it the world's first steam battleship. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of steam-powered versions of the traditional ships of the line, frigates, corvettes, sloops and gunboats.
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.
HMS Psyche was a 54-gun fourth-rate frigate of the Royal Navy. She was built at the Kingston Royal Naval Dockyard in Kingston, Upper Canada during the War of 1812, using frames shipped from Britain and assembled in Upper Canada. The ship was not completed until after the end of the war in 1815 and did not enter service. Under the Rush–Bagot Treaty of 1816, the frigate was disarmed and laid up at Kingston. The ultimate fate of the ship is unknown.
HMS Rattler was a 9-gun steam screw sloop of the Royal Navy, and one of the first British warships to be completed with screw propulsion. She was originally ordered as a paddle wheel 4-gun steam vessel from Sheerness Dockyard on 12 March 1841. She was reordered on 24 February 1842 as a propeller type 9-gun sloop from HM Royal Dockyard, Sheerness, as a new vessel. William Symonds had redesigned the ship as a screw propeller driven vessel.
Sixteen ships of the Royal Navy have been named HMS Pelican, after the bird, while another was planned:
HMS Miranda was a 14-gun wooden screw sloop of the Royal Navy. As part of the 1847 Program, she was designed by John Fincham, Master Shipwright of Portsmouth ,and is considered an improved Rattler, with the design approved on 3 November 1847. She was ordered on 25 April 1847 with the name Grinder from Royal Dockyard, Sheerness. On 3 November 1847, she was reordered as Miranda from Sheerness Dockyard. Launched in 1851, she was completed to see action in the Crimean War. In 1854 she was in the White Sea and participated in the bombardment of the Port of Kola. She then served in the Sea of Azov during 1855. Two of her crew were awarded the Victoria Cross for their bravery. Towards the end of her career she transported troops during the New Zealand Wars. She was reclassified as a corvette by 1862. She was sold for breaking in December 1869.
USS Underwriter was a 341-ton sidewheel steamer that was purchased for military use by the Union Navy during the American Civil War.
The Iris class consisted of two ships, HMS Iris and HMS Mercury, built for the Royal Navy in the 1870s. They were the first British all-steel warships.
HMS Iris the lead ship of her class of two ships built for the Royal Navy in the 1870s. They were the first all-steel warships to serve with the Royal Navy.
HMS Cormorant was an Osprey-class sloop launched at Chatham on 12 September 1877 and later the receiving ship at Gibraltar. She was renamed Rooke in 1946 and broken up in 1949.
HMS Penguin was an Osprey-class sloop. Launched in 1876, Penguin was operated by the Royal Navy from 1877 to 1881, then from 1886 to 1889. After being converted to a survey vessel, Penguin was recommissioned in 1890, and operated until 1908, when she was demasted and transferred to the Australian Commonwealth Naval Forces for use as a depot and training ship in Sydney Harbour. After this force became the Royal Australian Navy, the sloop was commissioned as HMAS Penguin in 1913. Penguin remained in naval service until 1924, when she was sold off and converted into a floating crane. The vessel survived until 1960, when she was broken up and burnt.
HMS Espiegle was a Doterel-class sloop of the Royal Navy, built at the Devonport Dockyard and launched on 3 August 1880.
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 Dragon was a Doterel-class sloop of the Royal Navy, built at Devonport Dockyard and launched on 30 May 1878. She served in the East Indies, including the Anglo-Egyptian War of 1882, and the suppression of slavery. She was sold for breaking in 1892.
HMS Wild Swan was an Osprey-class sloop built for the Royal Navy in the mid-1870s. She was launched in 1877 and became a base ship in 1904, being renamed Clyde. She was renamed Columbine in 1913 and was sold for breaking in 1920.
HMS Magicienne was the lead ship of her class of two 16-gun, steam-powered second-class paddle frigates built for the Royal Navy in the 1850s. Commissioned in 1853 she played a small role in the Crimean War of 1854–1855 and was sold for scrap in 1866.
This group of vessels were originally slated to be built to the Sampson designed steam vessel; however, the Admiralty on 9 May 1845, ordered the first pair as First-Class screw sloops to be built from a design of Sir William Symonds, Surveyor of the Navy. This design would become known as the Conflict-class sloop. These would be 10-gun vessels with 400 NHP engines. The second pair of vessels were ordered on 26 March 1846 but after their keels were laid at Pembroke Dockyard, their construction was suspended in September 1846 then cancelled five years later, on 4 April 1851. Both completed ships served in the Baltic during the Crimean war, and Desperate briefly served as a store ship to Edward Augustus Inglefield's Arctic expedition. They had both been broken up by 1865.
HMS Hearty was a fishery protection vessel and survey ship of the British Royal Navy. Built by the Scottish shipbuilder W. B. Thompson as the tug Indra, the ship was launched in 1885 and purchased by the Royal Navy. Hearty was sold in 1920 for use as a salvage vessel. She was renamed Dalhousie in 1921, and was sold for scrap in 1930, being scrapped in 1935.
The Bulldog-class steam vessels (SV2) later reclassed as First Class Sloops, were designed by Sir William Symonds, the Surveyor of the Navy. Designed from the Driver class by Admiralty Order of 26 December 1843, the design was approved in 1844. The changes included lengthening the bow by 10 feet to provide 6 feet of extra space in the engine room. Three vessels would have a single funnel whereas Scourge would have two and be completed as a bomb vessel. In July 1844 it was queried if Fury was to be completed as a screw vessel, however, since her construction was well along she would be completed as a paddle steamer. Four vessels were ordered and completed.
