Steam frigates (including screw 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. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats.
The first small vessel that can be considered a steam warship was the Demologos , which was launched in 1815 for the United States Navy. [1] From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs HMS Comet and HMS Monkey, and by the 1830s the navies of America, Russia and France were experimenting with steam-powered warships. [2] Hellenic sloop-of-war Kartería (Καρτερία; Greek for "Perseverance") was the first steam-powered warship to be used in combat operations in history. It was built in 1825 in an English shipyard for the revolutionary Hellenic Navy during the Greek War of Independence, on the order of Capt Frank Abney Hastings, a former Royal Navy officer who had volunteered his services to the Hellenic Navy.
The frigate and corvette were 'ships'. For a vessel to be called a 'ship' it had to have full rigging, i.e. square rigs on three masts. If it had only fore-and-aft rig on the mizzen mast, it was not a ship. Ships were classified as: ships of the line, frigates and corvettes.
The upper limit for a ship to be still considered a frigate was that it had only one covered gun deck. If a ship had two covered gun decks, it was no longer a frigate, but a ship of the line. A confusing circumstance arose when in the early nineteenth century the forecastle and quarterdecks of most big ships were joined to become a complete flush deck above. [3] These ships continued to be frigates, e.g HMS Constance (1846).
The lower limit for a ship to still be considered a frigate was that its gun deck was covered. If a ship had only a single open gun deck it was considered to be 'corvette build'. [4] If a ship had a single covered gun deck, it was at least a frigate.
In general a frigate was commanded by a captain and a corvette by a lieutenant.
This first generation of steam warships were "paddle warships" (in the categories of frigate, sloop, gunvessel or other). They used paddlewheels mounted on either side or in the center. Paddle steamers were severely limited in the armaments they could mount. Paddle wheel propulsion also had very serious effects on sailing quality. The placement of the machinery and wheels in the middle of the ship conflicted with having the main mast there, and so the sail plan of paddle frigates was less than ideal. Another characteristic that slowed down these vessels was that the paddle wheels would rotate in the water freely when the ship was sailing.
The armament of paddle frigates compared badly with their sail-only counterparts. Paddle frigates could not have a traditional full broadside because of the space taken by the machinery and the paddle wheels. The weight of the machinery and coal these ships carried was a perhaps even more serious problem. It meant that the designers had to limit the weight of all other 'cargo', including artillery. [5] Therefore the armament of steam vessels had to follow a different concept: Because of their ability to move against the wind they could be assumed to be able to choose their distance to sail-only ships. Under these circumstances the very heavy guns that were deemed to fire too slowly for close-quarters combat did become useful because they had a high effective range. Meanwhile, the development of heavy shell guns like the ML 8-inch shell gun provided a long range weapon that could sink a ship with a single hit. The only means to counter it was to develop heavier solid shot cannon that had an even higher effective range. All this generally led to equipping early steamers with only a few very heavy guns, both shell guns and solid shot guns. These were often mounted on pivots and slides.
Paddle frigates were used extensively during the Opium Wars, Mexican–American War, Crimean War and American Civil War. An unintended quality was that the lack of broadside batteries gave them very spacious decks. Combined with being immune to contrary winds, this made them ideal for large scale troop transport. By 1870 most had been scrapped or sold into civilian service. [6]
By 1840 the Royal Navy had commissioned two ships that had been designed as steam paddle frigates. HMS Gorgon and the slightly larger HMS Cyclops had both been constructed to have a full battery on their gun deck, next to carrying guns on their upper decks. However, Gorgon was so deep in the water that her gun ports had to be shut permanently. Cyclops had been designed to carry 16 32-pounders on the main deck, but these could not be fitted. [7] Both ships therefore failed to become true frigates, but were nevertheless very successful. The Cyclops would be taken as a model to build six more of these steam frigates (Vulture, Firebrand, Gladiator, Sampson, Dragon and Centaur). [8] On 31 May 1844 the Admiralty then officially adopted the term 'Steam frigate'. All these ships became steam (paddle) frigates of the second class, except for Gorgon, which became a sloop. [9]
The rating of Cyclops as a 'steam frigate' was surprising: she was rigged as a brig (with only two masts), and carried all her guns on the upper deck [7] Other aspects did explain this classification. The Cyclops was commanded by a captain and had at least been planned to have a 'complete' covered gun deck. The crew of 175 men was a reduced crew. [10] By counting 13 men for every two 32-pounders, the designed complement would be 175 + (8*13) = 284 men, almost matching that of a fifth rate frigate. Another reason to rate the Cyclops as a frigate was that with her size of 1,190 bm tons, she was of the same size as the fifth rate frigates like those of the Seringapatam-class frigate of 1,150 bm tons. As the RN lacked a corvette category, the alternative would have been to rate her as a sloop, but even ship-rigged sloops did not get near her size. When the RN started to use the designation corvette, the Cyclops and her six near sisters were re-classified as corvettes in the 1850s. [9]
In 1844 the Admiralty also discerned steam frigates of the first class, these steam frigates had guns on two decks. [9] The steam frigates of the 'first class' were comparable to regular fourth rate sailing frigates in terms of size, and got near them in armament. The first of these was the paddle steamer HMS Penelope commissioned in 1843. She had been the sailing fifth rate frigate Penelope of 1829. In 1842 she was lengthened by 63 feet, and was fitted with the largest naval steam engines yet seen, generating nearly 700 horsepower. She had a 330 men crew, and was armed with 10 68-pounders on the main deck, and on the forecastle and quarterdeck: two 85 cwt pivot guns, 10 42-pounders carronades and 4 howitzers. [11]
Penelope was followed by even bigger ships like HMS Retribution and HMS Terrible. Other steam frigates first class, like HMS Avenger were a bit smaller. Only five first class steam paddle frigates would be built by the Royal Navy. The RN also built some more steam frigates of the second class, surprisingly with guns on two decks.
The United States Navy likewise started with a general 'steamer' class. In 1842 it consisted of USS Fulton (1837) of 4 guns, commissioned in 1837, and USS Union (1842) (with a horizontal submerged paddle). Union was not yet armed, but would later also have 4 guns. USS Poinsett (1840) was a smaller craft that would later be armed with 2 guns. By then the U.S. Navy already had the screw corvette USS Princeton (1843) under construction.
The first steam frigates of the United States were USS Mississippi (1841) and USS Missouri (1841). These were two very big steam paddle frigates commissioned in 1841 and 1842. They each displaced 3,220t and had 10 big Paixhans guns. [12] By 1850 the U.S. paddle steamers were divided into classes. Mississippi was designated a steam frigate, and so were USS Susquehanna (1850) and USS Powhatan (1850), each with 9 heavy guns, and USS San Jacinto (1850) and USS Saranac (1848) each with 6 heavy guns. The next class were the 'steamers first class', containing Fulton, USS Michigan (1843) and USS Allegheny (1847). Seven other steamers were 'less than first class' [13]
The Russian Tsarist Navy also had a sizable fleet of paddle steam frigates. The first of these were imported from America, but by the time of the Crimean War the Russians were producing their own steamships. The 1841 steam frigate Kamchatka had 16 guns on two decks, and was therefore comparable to the big frigates of the English and American navies. See also List of Russian steam frigates.
The first useful steam vessel of the French Navy was Sphinx of 160 hp and 913t displacement. She was used in the invasion of Algiers in 1830. She was not very useful as a warship, but she was very useful for maintaining communications with Algeria. The subsequent campaign caused a huge demand for frequent and reliable communication with Algeria, and so about two dozen ships were built to the model of Sphinx. The side effect was a stagnation in French steam vessel engineering. [14] Continuing the Sphinx type meant that France was not developing something that resembled a steam frigate.
Later on, the French state wanted to establish packet boat lines to New York, the West Indies and Brazil. The French navy wanted to have big steam frigates with heavy artillery. In 1840 these ideas were combined in a law that granted a credit of 28,400,000 francs for the construction of 14 ships of 450 hp, and 4 of 220 hp. The frigates built for this service soon proved to be no match for the ships of the Cunard Line. A project that lent four of them to a commercial company soon failed. [15] Gomer was the first of these large frigates, and created quite a sensation. She was 70.5 m long between perpendiculars, had a beam of 12.7 m and displaced about 2,800 t. On the trial run she was armed with 20 30-pounders on the main deck, and on the upper deck 2 22 cm and 2 16 cm, and had a complement of 300 men. [16] However, in actual use this artillery proved to be way more than what Gomer could handle. It had to be reduced to 2 80s and 6 30s. [17] It meant that Gomer had failed as a steam frigate. The same could be said of her (near) sisters of 450 hp, Asmodéee and l'Infernal.
Screw warships were built with steam engines and screw propellers for propulsion. The first functional propeller, a shortened version of the Archimedes' screw, was invented independently by Francis Pettit Smith and John Ericsson in 1835. The technology of propeller or 'screw' propulsion was proven by 1845 after the Royal Navy evaluated the performance of Smith's seagoing steamship SS Archimedes in comparison with their own fleet of paddle steamers. The basic fighting capabilities of the screw warship were almost as good as those of the traditional sailing ship. Apart from spending weight on machinery and coal, the screw ship retained the full broadside battery lay-out. It therefore had a nearly as powerful armament as a sail-only ship. Unlike the paddle ship it had no vulnerable paddle-boxes. The ability to pick a fight or to evade a fight was what made the screw frigate superior to any sail-only ship.
The screw frigate retained a full sail-plan, and this was not only due to conservatism. The primary reason was a lack of coal supplies around the globe. This was an especially important consideration for frigates, which often operated independently on the far side of the world. The insufficient reliability of early steam engines was also a reason to maintain at least some sails. An often overlooked reason to have sails was the cost of coal. In 1848 the sail frigate HMS Thetis was estimated to cost 64 GBP daily to operate. HMS Terrible, of the same weight of armament, was estimated to cost 88 GBP daily. But, the latter was without the cost of coal, estimated at 4 pounds 5 shillings per hour of steaming. [18]
The 'screw frigates', built first of wood and later of wrought iron, continued to perform the traditional role of the frigate until late in the 19th century.
By the late 1840s many navies were building screw-driven warships or converting sailing ships to include screw propulsion. In 1852 the French navy commissioned the Napoleon , the first screw driven battleship. With that all sailing warships had gotten a screw driven equivalent.
By the time that the Royal Navy launched its first screw frigate, HMS Amphion, it already had two screw sloops in commission. The 9 gun sloop HMS Rattler, launched in 1843, was designed by Isambard Kingdom Brunel and featured an advanced two-bladed propeller that influenced the design of his later passenger steamer SS Great Britain. [19] [20] Amphion had 28 32-pounders and 8 heavier guns. The size and armament of British wooden screw frigates then rapidly increased. HMS Euryalus of 1853 was 65 m long, displaced 3,125 t, had twenty-eight 8 inch 65 cwt shell guns and twenty-two 32-pounders. The RN's first battleship designed for steam propulsion was HMS Agamemnon. She was 70 m long, displaced 4,614 t, and had thirty-four 8-inch 65 cwt and fifty-six 32-pounders. In 1852–1853, the distinction between battleship and frigate was still a matter of size and number of gun decks.
The improved screw propeller invented by Brunel also enabled the Victorian Royal Navy to extend the service life of obsolete sail-powered ships of the line. HMS Erebus and HMS Terror, first commissioned during the War of 1812, were fitted with steam locomotive boilers in 1845 for the Franklin expedition. The paddle sloop HMS Phoenix was later rebuilt with a propeller for service in the Crimean War. [21]
In the late 1850s the screw frigate began to take a different form than traditional ships of the line. The RN's last battleship, the 91 gun HMS Defiance laid down in 1858, was 75 m long and displaced 5,700 t. The screw frigate HMS Shannon was much smaller at 3,915 t, but nevertheless much longer at 87 m. This development of much longer frigates culminated in HMS Mersey of 1858. Mersey had 40 heavy shell guns, reached an overall length of over 100 m and displaced 5,463 t. A wooden construction proved to be too weak for a ship of this length. The next steps were frigates with an iron or composite hull: the armored frigate and the unarmored frigate.
The Pomone of 1842 was the first French screw frigate. She was 52 m long, 13.5 m wide, and had a slightly changed sail plan of a 46 gun frigate. She had 18 30-pounders on the gun deck, and 8 80-pounders and 8 other guns on the upper decks. The engine of the Pomone was 220 hp, giving her a speed of 7.5 knots. Using both sail and engine she could make 10.5 kn. Sailing before the wind, however she reached 12 kn without engines. [22]
The French navy next built the L'Isly, converted a number of sailing frigates, and built a range of successful corvettes. In 1852 a program for a number of first rate frigates was started. The Impératrice Eugénie class of 5 ships was built according to a design by Henri Dupuy de Lôme. Georges Baptiste François Allix designed the Souveraine. On average these ships displaced 3,800 t and reached 12 kn on trials. [23] In 1857 the French government decided to have 6 big and 14 smaller frigates.
From 1859, armor was added to ships based on existing frigate and ship of the line designs. The additional weight of the armour on these first ironclad warships meant that they could have only one gun deck, and they were technically frigates, even though they were more powerful than existing ships-of-the-line and occupied the same strategic role. The phrase 'armoured frigate' remained in use for some time to denote a sail-equipped, broadside-firing type of ironclad. For a time, they were the most powerful type of vessel afloat.
Towards the end of the 19th century, the term 'frigate' fell out of use. Armoured vessels were designated as either 'battleships' or 'armoured cruisers', while unarmoured vessels including frigates and sloops were classified as 'unprotected cruisers'.
The only surviving screw frigate is the Danish Jylland .
The steam sloop HMS Gannet spent many years as a training ship and is now preserved at Chatham.
The Dutch gunvessel HNLMS Bonaire is currently undergoing restoration as a museum ship.[ when? ]
ARA Uruguay of the Argentinian navy is the last surviving steam and sail corvette.
The Japanese frigate Kaiyō Maru was rebuilt as a museum ship in 1990.
A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.
A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which involved the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firing – and therefore more firepower – typically had an advantage.
An ironclad is a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships.
A warship or combatant ship is a ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a nation. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies.
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.
A screw sloop is a propeller-driven sloop-of-war. They were popularized in the mid-19th century, during the introduction of the steam engine and the transition of fleets to this new technology.
In the rating system of the Royal Navy used to categorise sailing warships, a sixth-rate was the designation for small warships mounting between 20 and 28 carriage-mounted guns on a single deck, sometimes with smaller guns on the upper works and sometimes without. It thus encompassed ships with up to 30 guns in all. In the first half of the 18th century the main battery guns were 6-pounders, but by mid-century these were supplanted by 9-pounders. 28-gun sixth rates were classed as frigates, those smaller as 'post ships', indicating that they were still commanded by a full ('post') captain, as opposed to sloops of 18 guns and less under commanders.
The rating system of the Royal Navy and its predecessors was used by the Royal Navy between the beginning of the 17th century and the middle of the 19th century to categorise sailing warships, initially classing them according to their assigned complement of men, and later according to the number of their carriage-mounted guns. The rating system of the Royal Navy formally came to an end in the late 19th century by declaration of the Admiralty. The main cause behind this declaration focused on new types of gun, the introduction of steam propulsion and the use of iron and steel armour which made rating ships by the number of guns obsolete.
Demologos was the first warship to be propelled by a steam engine. She was a wooden floating battery built to defend New York Harbor from the Royal Navy during the War of 1812. The vessel was designed to a unique pattern by Robert Fulton, and was renamed Fulton after his death. Because of the prompt end of the war, Demologos never saw action, and no other ship like her was built.
The Calypso class comprised two steam corvettes of the Royal Navy. Built for distant cruising in the heyday of the British Empire, they served with the fleet until the early twentieth century, when they became training ships. Remnants of both survive, after a fashion; HMS Calliope in the name of the naval reserve unit the ship once served, and HMS Calypso both in the name of a civilian charity and the more corporeal form of the hull, now awash in a cove off Newfoundland.
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.
The Medusa class was a class of two steam corvettes with auxiliary power of the Royal Netherlands Navy. The class comprised Medusa, the first Dutch warship with screw propulsion, and Prinses Amelia.
HMS Penelope was first laid down as one of the many sail frigates that England built to a French model. She was then changed to a unique steam paddle frigate. For some time she was a very famous ship, having a claim to being the first steam frigate. In the end the promise that she would be the first of a line of true steam paddle frigates proved false.
HMS Cyclops was a paddle wheel steam frigate built for the Royal Navy and launched in 1839 and taken out of service in 1861 and sold for breaking in January 1864. She saw action in the Syrian War in 1840 and the Crimean War in 1854, later being involved in laying the first Transatlantic telegraph cable in 1858.
The Thames-class frigate was a 32-gun fifth-rate frigate class of eight ships of the Royal Navy based on the Richmond-class frigate designed by William Bately. The ships were ordered to the older design, which was of a smaller type of ship compared to more modern designs, so that they could be built quickly and cheaply in time to assist in defending against Napoleon's expected invasion of Britain. The class received several design changes to the Richmond class, being built of fir instead of oak, with these changes making the class generally slower and less weatherly than their predecessors, especially when in heavy weather conditions. The first two ships of the class, Pallas and Circe, were ordered on 16 March 1804 with two more ordered on 1 May and the final four on 12 July. The final ship of the class, Medea, was cancelled on 22 October before construction could begin but the other seven ships of the class were commissioned between 1804 and 1806.
The Anna Paulowna class was a class of steam frigates of the Royal Netherlands Navy. Only Anna Paulowna was completed, parts of Van Galen were used to build the steam corvette Zilveren Kruis.
This glossary defines the various types of ships and accessory watercraft that have been used in service of the United States. Such service is mainly defined as military vessels used in the United States Navy and United States Coast Guard, as well as the defunct, incorporated, or renamed institutions such as the United States Revenue Cutter Service. Service of the United States can also be defined in this context as special government missions in the form of expeditions, such as the Wilkes Expedition or the North Pacific Exploring and Surveying Expedition. The scope of the glossary encompasses both the "Old Navy" of the United States, from its beginnings as the "Continental Navy", through the "New Navy" and up to modern day. The watercraft included in the glossary are derived from United States ships with logbooks published by the National Archives and Records Administration.
HMS Pylades was the sole member of the Pylades-class of first-class screw corvettes that served in the Victorian Royal Navy. Pylades was a development of the previous Highflyer class with a greater beam. The vessel served under two commanders who later became admirals, Captains Arthur Acland Hood and Edwin Tennyson d'Eyncourt. A third commander was Captain Michael de Courcy, remembered in the name of De Courcy Island, one of the Gulf Islands off the coast of British Columbia along with Pylades Island, which is named for the corvette. In 1855, Pylades served in the Baltic Sea during the Crimean War. In 1859, the vessel was the last Royal Navy warship to visit the San Juan Islands during the San Juan Boundary Dispute. In 1863, the ship's presence helped diffuse the Chesapeake affair that could have led to the British Empire joining the American Civil War. After serving across the British Empire, the ship was decommissioned and sold to be broken up in 1875.
