Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships .
147-493: In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought . The name barbette ultimately comes from fortification : it originally meant a raised platform or mound, as in the French phrase en barbette , which refers to the practice of firing a cannon over a parapet rather than through an embrasure in
294-461: A main battery of very heavy guns upon the weather deck, in large rotating mounts either fully or partially armoured over, and supported by one or more secondary batteries of lighter weapons on broadside. The similarity in appearance of battleships in the 1890s was underlined by the increasing number of ships being built. New naval powers such as Germany , Japan , the United States , and to
441-476: A torpedo , with less vulnerability to quick-firing guns. The armament of ironclads tended to become concentrated in a small number of powerful guns capable of penetrating the armor of enemy ships at range; calibre and weight of guns increased markedly to achieve greater penetration. Throughout the ironclad era navies also grappled with the complexities of rifled versus smoothbore guns and breech-loading versus muzzle-loading . HMS Warrior carried
588-474: A barbette is a position on an aircraft where a gun is in a mounting which has a restricted arc of fire when compared to a turret, or which is remotely mounted away from the gunner. As such it is frequently used to describe the tail gunner position on bombers such as the Boeing B-17 Flying Fortress , with American aviation books frequently describing the position as a tail gun turret, or simply as
735-420: A breech, adopted by the French in 1873. Just as compellingly, the growing size of naval guns and consequently, their ammunition, made muzzle-loading much more complicated. With guns of such size there was no prospect of hauling in the gun for reloading, or even reloading by hand, and complicated hydraulic systems were required for reloading the gun outside the turret without exposing the crew to enemy fire. In 1882,
882-419: A carriage that retracted behind a parapet for reloading; this better protected the crew, and made the gun harder to target, since it was only visible while it was firing. The type was usually used for coastal defence guns. As naval gun turrets improved to allow greater elevation and range, many disappearing guns, most of which were limited in elevation, were seen as obsolescent; with aircraft becoming prominent in
1029-492: A claim to the title of the first ironclad warships but they were capable of only 4 knots (7.4 km/h; 4.6 mph) under their own power: they operated under their own power at the Battle of Kinburn, but had to be towed for long-range transit. They were also arguably marginal to the work of the navy. The brief success of the floating ironclad batteries convinced France to begin work on armored warships for their battlefleet. By
1176-617: A clash between Chinese battleships and a Japanese fleet consisting of mostly cruisers. The Spanish–American War of 1898 was also a mismatch, with the American pre-dreadnought fleet engaging Spanish shore batteries at San Juan and then a Spanish squadron of armoured cruisers and destroyers at the Battle of Santiago de Cuba . Not until the Russo-Japanese War of 1904–05 did pre-dreadnoughts engage on an equal footing. This happened in three battles:
1323-564: A few rounds. Smoke and the general chaos of battle only added to the problem. As a result, many naval engagements in the 'Age of the Ironclad' were still fought at ranges within easy eyesight of their targets, and well below the maximum reach of their ships' guns. Another method of increasing firepower was to vary the projectile fired or the nature of the propellant. Early ironclads used black powder , which expanded rapidly after combustion; this meant cannons had relatively short barrels, to prevent
1470-415: A fortification's casemate . The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term
1617-687: A gun placed to fire over a parapet, rather than through an embrasure , an opening in a fortification wall. While an en barbette emplacement offered wider arcs of fire, it also exposed the gun's crew to greater danger from hostile fire. In addition, since the barbette position would be higher than a casemate position—that is, a gun firing through an embrasure—it would generally have a greater field of fire. The American military theorist Dennis Hart Mahan suggested that light guns, particularly howitzers , were best suited for barbette emplacements since they could fire explosive shells and could be easily withdrawn when they came under enemy fire. Fortifications in

#17329097650461764-476: A harbour-defence vessel; she fired at extreme range (13,500 yards, 12,300 m) on the German cruiser SMS Gneisenau , and while the only hit was from an inert practice shell which had been left loaded from the previous night (the "live" shells of the salvo broke up on contact with water; one inert shell ricocheted into one of Gneisenau ' s funnels), this certainly deterred Gneisenau . The subsequent battle
1911-628: A lesser extent Italy and Austria-Hungary , began to establish themselves with fleets of pre-dreadnoughts. Meanwhile, the battleship fleets of the United Kingdom, France , and Russia expanded to meet these new threats. The last decisive clash of pre-dreadnought fleets was between the Imperial Japanese Navy and the Imperial Russian Navy at the Battle of Tsushima on 27 May 1905. These battleships were abruptly made obsolete by
2058-401: A low freeboard to reduce topweight and a corresponding tendency to capsize . By the 1870s, designers had shifted to the rotating barbette mount, which eschewed armor protection to reduce weight; this would permit the use of heavy guns in high-freeboard ships. This new type of vessel was referred to as a barbette ship , to differentiate them from turret ships and central battery ships . In
2205-539: A mixture of 110-pounder 7-inch (178 mm) breech-loading rifles and more traditional 68-pounder smoothbore guns. Warrior highlighted the challenges of picking the right armament; the breech-loaders she carried, designed by Sir William Armstrong , were intended to be the next generation of heavy armament for the Royal Navy, but were shortly withdrawn from service. Breech-loading guns seemed to offer important advantages. A breech-loader could be reloaded without moving
2352-424: A movement away from the ships mounting many guns broadside, in the manner of a ship-of-the-line, towards a handful of guns in turrets for all-round fire. From the 1860s to the 1880s many naval designers believed that the ram was again a vital weapon in naval warfare. With steam power freeing ships from the wind, iron construction increasing their structural strength, and armor making them invulnerable to shellfire,
2499-400: A number of innovations to increase the rate of fire. The propellant was provided in a brass cartridge, and both the breech mechanism and the mounting were suitable for rapid aiming and reloading. A principal role of the secondary battery was to damage the less armoured parts of an enemy battleship; while unable to penetrate the main armour belt, it might score hits on lightly armoured areas like
2646-510: A pre-dreadnought was not necessarily the equal of even a modern armoured cruiser, and was totally outclassed by a modern dreadnought battleship or battlecruiser. Nevertheless, the pre-dreadnought played a major role in the war. This was first illustrated in the skirmishes between British and German navies around South America in 1914. While two German cruisers menaced British shipping, the Admiralty insisted that no battlecruisers could be spared from
2793-430: A remotely operated twin- MG 131 machine gun Fernbedienbare Drehlafette FDL 131Z (Z – "zwilling" /twin) powered forward dorsal gun turret, with the full translation of the German term comprising the prefix as "Remotely controlled rotating gun mount". The term "lafette" in German actually refers to a gun carriage of nearly any type, with its original use as being for the mounting design for bombard -style siege guns of
2940-546: A similar armament before Dreadnought , but were unable to complete them before the British ship. It was felt that because of the longer distances at which battles could be fought, only the largest guns were effective in battle, and by mounting more 12-inch guns Dreadnought was two to three times more effective in combat than an existing battleship. The armament of the new breed of ships was not their only crucial advantage. Dreadnought used steam turbines for propulsion, giving her
3087-501: A tail gun. The term "barbette" is also used by some, again primarily British historians, to describe a remotely aimed and operated gun turret emplacement on almost any non-American military aircraft of World War II, but it is not usable in a direct translation for the varying German language terms used on Luftwaffe aircraft of that era for such emplacements. As just one example, the German Heinkel He 177 A heavy bomber had such
SECTION 20
#17329097650463234-427: A top speed of 21 knots, against the 18 knots typical of the pre-dreadnought battleships. Able both to outgun and outmaneuver their opponents, the dreadnought battleships decisively outclassed earlier battleship designs. Nevertheless, pre-dreadnoughts continued in active service and saw significant combat use even when obsolete. Dreadnoughts and battlecruisers were believed vital for the decisive naval battles which at
3381-534: A total of more than 145,000 passengers. Ironclad warship An ironclad was 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
3528-465: A trajectory close to horizontal) was a much greater threat than had been thought. Gunboat diplomacy was typically conducted by cruisers or smaller warships. A British squadron of three protected cruisers and two gunboats brought about the capitulation of Zanzibar in 1896; and while battleships participated in the combined fleet Western powers deployed during the Boxer Rebellion , the naval part of
3675-456: A turret, though the armored tube that held the turret substructure, which included the shell and propellant handling rooms and the ammunition hoists, was still referred to as a barbette. These ships were the prototype of the so-called pre-dreadnought battleships , which proved to be broadly influential in all major navies over the next fifteen years. When applied to military aircraft, largely in aviation history books written by British historians,
3822-488: A variety of ways; sometimes carried in turrets, they were just as often positioned in fixed armoured casemates in the side of the hull, or in unarmoured positions on upper decks. Some of the pre-dreadnoughts carried an "intermediate" battery, typically of 8-to-10-inch (203 to 254 mm) calibre. The intermediate battery was a method of packing more heavy firepower into the same battleship, principally of use against battleships or at long ranges. The United States Navy pioneered
3969-504: A wooden hull. Encouraged by the positive reports of the iron hulls of those ships in combat, the Admiralty ordered a series of experiments to evaluate what happened when thin iron hulls were struck by projectiles, both solid shot and hollow shells, beginning in 1845 and lasting through 1851. Critics like Lieutenant-general Sir Howard Douglas believed that the splinters from the hull were even more dangerous than those from wooden hulls and
4116-477: Is also used for certain aircraft gun mounts. Shipboard barbettes were primarily used in armoured warships, starting in the 1860s during a period of intense experimentation with other mounting systems for heavy guns at sea. In these, gun barrels usually protruded over the barbette edge, so barbettes provided only partial protection, mainly for the ammunition supply. Alternatives included the heavily-armoured gun turret and an armoured, fixed central gun battery . By
4263-575: The Lord Nelson class, carried ten 9.2-inch guns as secondary armament. Ships with a uniform, heavy secondary battery are often referred to as "semi-dreadnoughts". Pre-dreadnought battleships carried a considerable weight of steel armour, providing them with effective defence against the great majority of naval guns in service during the period. 'Medium' calibre guns up to 8-9.4 inch would generally prove incapable of piercing their thickest armour, while it still provided some measure of defence against even
4410-571: The Virginia class laid down in 1901–02. Nevertheless, it was these earlier ships that ensured American naval dominance against the antiquated Spanish fleet—which included no pre-dreadnoughts—in the Spanish–American War, most notably at the Battle of Santiago de Cuba. The final two classes of American pre-dreadnoughts (the Connecticut s and Mississippi s ) were completed after the completion of
4557-620: The 1898 and 1900 Navy Laws . This increase was due to the determination of the navy chief Alfred von Tirpitz and the growing sense of national rivalry with the UK. Besides the Brandenburg class, German pre-dreadnoughts include the ships of the Kaiser Friedrich III , Wittelsbach , and Braunschweig classes—culminating in the Deutschland class , which served in both world wars. On the whole,

4704-428: The Battle of Sinop , spelled the end of the wooden-hulled warship. The more practical threat to wooden ships was from conventional cannon firing red-hot shot, which could lodge in the hull and cause a fire or ammunition explosion. Some navies even experimented with hollow shot filled with molten metal for extra incendiary power. The use of wrought iron instead of wood as the primary material of ships' hulls began in
4851-533: The Battle of the Yellow Sea in 1904, the Russian and Japanese fleets fought at ranges of 3.5 miles (5.5 km). The increase in engagement range was due in part to the longer range of torpedoes, and in part to improved gunnery and fire control. In consequence, shipbuilders tended towards heavier secondary armament, of the same calibre that the "intermediate" battery had been; the Royal Navy's last pre-dreadnought class,
4998-583: The Borodino class. The weakness of Russian shipbuilding meant that many ships were built overseas for Russia; the best ship, the Retvizan , being largely constructed in the United States. The Russo-Japanese War of 1904–05 was a disaster for the Russian pre-dreadnoughts; of the 15 battleships completed since Petropavlovsk , eleven were sunk or captured during the war. One of these, the famous Potemkin , mutinied and
5145-556: The Dreadnought and after the start of design work on the USN's own initial class of dreadnoughts. The US Great White Fleet of 16 pre-dreadnought battleships circumnavigated the world from 16 December 1907, to 22 February 1909. Japan was involved in two of the three major naval wars of the pre-dreadnought era. The first Japanese pre-dreadnought battleships, the Fuji class , were still being built at
5292-580: The Gloire and her sisters had full iron-armor protection along the waterline and the battery itself. The British Warrior and Black Prince (but also the smaller Defence and Resistance ) were obliged to concentrate their armor in a central "citadel" or "armoured box", leaving many main deck guns and the fore and aft sections of the vessel unprotected. The use of iron in the construction of Warrior also came with some drawbacks; iron hulls required more regular and intensive repairs than wooden hulls, and iron
5439-561: The Majestic class onwards carried 12-inch weapons, as did French battleships from the Charlemagne class, laid down in 1894. Japan, importing most of its guns from Britain, used this calibre also. The United States used both 12-inch and 13-inch (330 mm) guns for most of the 1890s until the Maine class , laid down in 1899 (not the earlier Maine of Spanish–American War notoriety), after which
5586-537: The naval ram , the torpedo , or sometimes both (as in the case with smaller ships and later torpedo boats), which several naval designers considered the important weapons of naval combat. There is no clear end to the ironclad period, but toward the end of the 1890s, the term ironclad dropped out of use. New ships were increasingly constructed to a standard pattern and designated as battleships or armored cruisers . The ironclad became technically feasible and tactically necessary because of developments in shipbuilding in
5733-447: The screw propeller in the 1840s. Steam-powered screw frigates were built in the mid-1840s, and at the end of the decade the French Navy introduced steam power to its line of battle . Napoleon III 's ambition to gain greater influence in Europe required a sustained challenge to the British at sea. The first purpose-built steam battleship was the 90-gun Napoléon in 1850. Napoléon
5880-508: The "new naval powers" of Germany, Japan and the United States. The new ships of the Imperial Japanese Navy and to a lesser extent the U.S. Navy supported those powers' colonial expansion. While pre-dreadnoughts were adopted worldwide, there were no clashes between pre-dreadnought battleships until the very end of their period of dominance. The First Sino-Japanese War in 1894–95 influenced pre-dreadnought development, but this had been

Experience with the first generations of ironclads showed that rather than giving the ship's entire length uniform armour protection, it was best to concentrate armour in greater thickness over limited but critical areas. Therefore the central section of the hull, which housed the boilers and engines, was protected by

6174-512: The 12-inch gun was universal. The Russians used both 12 and 10-inch (254 mm) guns as their main armament; the Petropavlovsk class , Retvizan , Tsesarevich , and Borodino class had 12-inch (305 mm) main batteries while the Peresvet class mounted 10-inch guns. The first German pre-dreadnought class used an 11-inch (279 mm) gun but decreased to a 9.4-inch (239 mm) gun for
6321-658: The 1830s; the first "warship" with an iron hull was the gunboat Nemesis , built by Jonathan Laird of Birkenhead for the East India Company in 1839. There followed, also from Laird, the first full-sized warship with a metal hull, the 1842 steam frigate Guadalupe for the Mexican Navy . The latter ship performed well during the Naval Battle of Campeche , with her captain reporting that he thought that there were fewer iron splinters from Guadalupe ' s hull than from
6468-545: The 1880s because of the influence of the Jeune École doctrine, which favoured torpedo boats to battleships. After the Jeune École's influence faded, the first French battleship laid down was Brennus , in 1889. Brennus and the ships which followed her were individual, as opposed to the large classes of British ships; they also carried an idiosyncratic arrangement of heavy guns, with Brennus carrying three 13.4-inch (340 mm) guns and
6615-423: The 1880s has been criticized by historians. However, at least until the late 1870s, the British muzzle-loaders had superior performance in terms of both range and rate of fire than the French and Prussian breech-loaders, which suffered from the same problems as the first Armstrong guns. From 1875 onwards, the balance between breech- and muzzle-loading changed. Captain de Bange invented a method of reliably sealing
6762-694: The 1880s used compound engines , and by the end of the 1880s the even-more efficient triple expansion compound engine was in use. Some fleets, though not the British, adopted the quadruple-expansion steam engine. The main improvement in engine performance during the pre-dreadnought period came from the adoption of increasingly higher pressure steam from the boiler. Scotch marine boilers were superseded by more compact water-tube boilers , allowing higher-pressure steam to be produced with less fuel consumption. Water-tube boilers were also safer, with less risk of explosion, and more flexible than fire-tube types. The Belleville-type water-tube boiler had been introduced in
6909-524: The 19th century typically employed both casemate and barbette emplacements. For example, the Russian Constantine Battery outside Sevastopol was equipped with 43 heavy guns in its seaward side during the Crimean War in the mid-1850s; of these, 27 were barbette mounted, with the rest in casemates. A modified version of the barbette type was the disappearing gun , which placed a heavy gun on
7056-528: The 81-ton, 16-inch guns of HMS Inflexible fired only once every 11 minutes while bombarding Alexandria during the Urabi Revolt . The 102-long-ton (104 t), 450 mm (17.72 inch) guns of the Duilio class could each fire a round every 15 minutes. In the Royal Navy, the switch to breech-loaders was finally made in 1879; as well as the significant advantages in terms of performance, opinion
7203-580: The Admirals continued the trend of ironclad warships mounting gigantic weapons. The guns were mounted in open barbettes to save weight. Some historians see these ships as a vital step towards pre-dreadnoughts; others view them as a confused and unsuccessful design. The subsequent Royal Sovereign class of 1889 retained barbettes but were uniformly armed with 13.5-inch (343 mm) guns ; they were also significantly larger (at 14,000 tons displacement ) and faster (because of triple-expansion steam engines) than
7350-567: The Admirals. Just as importantly, the Royal Sovereign s had a higher freeboard, making them unequivocally capable of the high-seas battleship role. The pre-dreadnought design reached maturity in 1895 with the Majestic class . These ships were built and armoured entirely of steel, and their guns were now mounted in fully-enclosed rotating turrets. They also adopted 12-inch (305 mm) main guns , which, because of advances in gun construction and
7497-581: The British Royal Navy . However, Britain built the first completely iron-hulled warships. They were first used in warfare in 1862 during the American Civil War , when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia . Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as
SECTION 50
#17329097650467644-484: The British Admiralty agreed to build five armored floating batteries on the French plans. The French floating batteries were deployed in 1855 as a supplement to the wooden steam battle fleet in the Crimean War . The role of the battery was to assist unarmored mortar and gunboats bombarding shore fortifications. The French used three of their ironclad batteries ( Lave , Tonnante and Dévastation ) in 1855 against
7791-672: The British to equip ships with muzzle-loading weapons of increasing power until the 1880s. After a brief introduction of the 100-pounder or 9.2-inch (230 mm) smoothbore Somerset Gun , which weighed 6.5 long tons (6.6 t), the Admiralty introduced 7-inch (178 mm) rifled guns, weighing 7 long tons (7 t). These were followed by a series of increasingly mammoth weapons—guns weighing 12 long tons (12 t), 18 long tons (18 t), 25 long tons (25 t), 38 long tons (39 t) and finally 81 long tons (82 t), with caliber increasing from 8 inches (203 mm) to 16 inches (406 mm). The decision to retain muzzle-loaders until
7938-400: The British, the Royal Navy had 50 pre-dreadnought battleships ready or being built by 1904, from the 1889 Naval Defence Act's ten units onwards. Over a dozen older battleships remained in service. The last two British pre-dreadnoughts, the "semi-dreadnought" Lord Nelson s, appeared after Dreadnought herself. France, Britain's traditional naval rival, had paused its battleship building during
8085-607: The Confederacy ;– especially in Russia, the only country to openly support the Union through the war. Only CSS Stonewall was completed, and she arrived in Cuban waters just in time for the end of the war. Through the remainder of the war, ironclads saw action in the Union's attacks on Confederate ports. Seven Union monitors, including USS Montauk , as well as two other ironclads,
8232-594: The Crimean War, Emperor Napoleon III ordered the development of light-draft floating batteries, equipped with heavy guns and protected by heavy armor. Experiments made during the first half of 1854 proved highly satisfactory, and on 17 July 1854, the French communicated to the British Government that a solution had been found to make gun-proof vessels and that plans would be communicated. After tests in September 1854,
8379-463: The First World War, they were largely seen as obsolete. However, they remained in use through the early Second World War, at least by the United States, due to limited funding for replacement weapons between the wars. Later heavy coastal guns were often protected in hybrid installations, in wide casemates with cantilevered overhead cover partially covering a barbette or gunhouse mount. Following

The engines drove either two or three screw propellers . France and Germany preferred the three-screw approach, which allowed the engines to be shorter and hence more easily protected; they were also more maneuverable and had better resistance to accidental damage. Triple screws were, however, generally larger and heavier than
8673-535: The German ships were less powerful than their British equivalents but equally robust. Russia equally entered into a programme of naval expansion in the 1890s; one of Russia's main objectives was to maintain its interests against Japanese expansion in the Far East. The Petropavlovsk class begun in 1892 took after the British Royal Sovereign s; later ships showed more French influence on their designs, such as
8820-550: The Middle Ages. Pre-dreadnought Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s . Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were
8967-512: The Russian tactical victory during the Battle of Port Arthur on 8–9 February 1904, the indecisive Battle of the Yellow Sea on 10 August 1904, and the decisive Japanese victory at the Battle of Tsushima on 27 May 1905. These battles upended prevailing theories of how naval battles would be fought, as the fleets began firing at one another at much greater distances than before; naval architects realized that plunging fire (explosive shells falling on their targets largely from above, instead of from

Pre-dreadnoughts were also used to support the Gallipoli landings, with the loss of three more: HMS Goliath , HMS Triumph and HMS Majestic . In return, a pair of Ottoman pre-dreadnoughts, the ex-German Turgut Reis and Barbaros Hayreddin , bombarded Allied forces during the Gallipoli campaign until
9261-473: The Union, but they were adequate for their intended use. More Western Flotilla Union ironclads were sunk by torpedoes (mines) than by enemy fire, and the most damaging fire for the Union ironclads was from shore installations, not Confederate vessels. The first fleet battle, and the first ocean battle, involving ironclad warships was the Battle of Lissa in 1866. Waged between the Austrian and Italian navies,
9408-527: The United Kingdom soon managed to take the lead in production. Altogether, France built ten new wooden steam battleships and converted 28 from older ships of the line, while the United Kingdom built 18 and converted 41. The era of the wooden steam ship-of-the-line was brief, because of new, more powerful naval guns. In the 1820s and 1830s, warships began to mount increasingly heavy guns, replacing 18- and 24-pounder guns with 32-pounders on sailing ships-of-the-line and introducing 68-pounders on steamers. Then,
9555-421: The action was performed by gunboats, destroyers and sloops. European navies remained dominant in the pre-dreadnought era. The Royal Navy remained the world's largest fleet, though both Britain's traditional naval rivals and the new European powers increasingly asserted themselves against its supremacy. In 1889, Britain formally adopted a "two-power standard" committing it to building enough battleships to exceed
9702-565: The armored frigate New Ironsides and a light-draft USS Keokuk , participated in the failed attack on Charleston ; one was sunk. Two small ironclads, CSS Palmetto State and CSS Chicora participated in the defense of the harbor. For the later attack at Mobile Bay , the Union assembled four monitors as well as 11 wooden ships, facing the CSS ; Tennessee , the Confederacy's most powerful ironclad, and three gunboats . On
9849-466: The arrival of HMS Dreadnought in 1906. Dreadnought followed the trend in battleship design to heavier, longer-ranged guns by adopting an "all-big-gun" armament scheme of ten 12-inch guns . Her innovative steam turbine engines also made her faster. The existing battleships were decisively outclassed, with no more being designed to their format thereafter; the new, larger and more powerful, battleships built from then on were known as dreadnoughts . This
9996-403: The barrel itself slowing the shell. The sharpness of the black powder explosion also meant that guns were subjected to extreme stress. One important step was to press the powder into pellets, allowing a slower, more controlled explosion and a longer barrel. A further step forward was the introduction of chemically different brown powder which combusted more slowly again. It also put less stress on
10143-563: The battle pitted combined fleets of wooden frigates and corvettes and ironclad warships on both sides in the largest naval battle between the battles of Navarino and Tsushima . The Italian fleet consisted of 12 ironclads and a similar number of wooden warships, escorting transports which carried troops intending to land on the Adriatic island of Lissa. Among the Italian ironclads were seven broadside ironclad frigates, four smaller ironclads, and
10290-514: The battle, the pre-dreadnoughts risked themselves by turning on the British battlefleet as dark set. Nevertheless, only one of the pre-dreadnoughts was sunk: SMS Pommern went down in the confused night action as the battlefleets disengaged. Following the November 1918 Armistice, the U.S. Navy converted fifteen older battleships, eight armoured cruisers and two larger protected cruisers for temporary service as transports. These ships made one to six trans-Atlantic round-trips each, bringing home
10437-410: The bridge, or start fires. Equally important, the secondary armament was to be used against smaller enemy vessels such as cruisers , destroyers , and even torpedo boats . A medium-calibre gun could be expected to penetrate the light armour of smaller ships, while the rate of fire of the secondary battery was important in scoring a hit against a small, manoeuvrable target. Secondary guns were mounted in
10584-419: The broadside-firing, masted designs of Gloire and Warrior . The clash of the Italian and Austrian fleets at the Battle of Lissa (1866), also had an important influence on the development of ironclad design. The first use of ironclads in combat came in the U.S. Civil War . The U.S. Navy at the time the war broke out had no ironclads, its most powerful ships being six unarmored steam-powered frigates. Since
10731-578: The bulk of the Navy remained loyal to the Union, the Confederacy sought to gain advantage in the naval conflict by acquiring modern armored ships. In May 1861, the Confederate Congress appropriated $ 2 million dollars for the purchase of ironclads from overseas, and in July and August 1861 the Confederacy started work on construction and converting wooden ships. On 12 October 1861, CSS Manassas became
10878-699: The concept of the battlecruiser . The Austro-Hungarian Empire also saw a naval renaissance during the 1890s, though of the nine pre-dreadnought battleships ordered only the three of the Habsburg class arrived before Dreadnought made them obsolete. The United States started building its first battleships in 1891. These ships were short-range coast-defence battleships that were similar to the British HMS ; Hood except for an innovative intermediate battery of 8-inch guns. The US Navy continued to build ships that were relatively short-range and poor in heavy seas, until
11025-489: The core of the fleet which twice engaged the numerically superior Russian fleets at the Battle of the Yellow Sea and the Battle of Tsushima. After capturing eight Russian battleships of various ages, Japan built several more classes of pre-dreadnoughts after the Russo-Japanese War. In 1906, the commissioning of HMS Dreadnought brought about the obsolescence of all existing battleships. Dreadnought , by scrapping
11172-523: The critics and ordered that the four iron-hulled propeller frigates ordered by the Tories be converted into troopships . No iron warships would be ordered until the beginning of the Crimean War in 1854. Following the demonstration of the power of explosive shells against wooden ships at the Battle of Sinop , and fearing that his own ships would be vulnerable to the Paixhans guns of Russian fortifications in
11319-563: The day was that wrought iron begins to become brittle at temperatures below 20 °C (68 °F). Many of the tests were conducted at temperatures below this while the battles were fought in tropical climates. The early experimental results seemed to support the critics and party politics came into play as the Whig First Russell ministry replaced the Tory Second Peel Ministry in 1846. The new administration sided with
11466-412: The decade before the first ironclads. In the 18th and early 19th centuries, fleets had relied on two types of major warship, the ship of the line and the frigate . The first major change to these types was the introduction of steam power for propulsion . While paddle steamer warships had been used from the 1830s onward, steam propulsion only became suitable for major warships after the adoption of
11613-654: The defenses at the Battle of Kinburn on the Black Sea , where they were effective against Russian shore defences. They would later be used again during the Italian war in the Adriatic in 1859. The British floating batteries Glatton and Meteor arrived too late to participate to the action at Kinburn. The British planned to use theirs in the Baltic Sea against the well-fortified Russian naval base at Kronstadt. The batteries have
11760-431: The end of the 1850s it was clear that France was unable to match British building of steam warships, and to regain the strategic initiative a dramatic change was required. The result was the first ocean-going ironclad, Gloire , begun in 1857 and launched in 1859. Gloire ' s wooden hull was modelled on that of a steam ship of the line, reduced to one deck, and sheathed in iron plates 4.5 inches (114 mm) thick. She
11907-422: The explosive conversion of a solid propellant into gas. This explosion propels the shot or shell out of the front of the gun, but also imposes great stresses on the gun-barrel. If the breech—which experiences some of the greatest forces in the gun—is not entirely secure, then there is a risk that either gas will discharge through the breech or that the breech will break. This in turn reduces the muzzle velocity of
12054-406: The extremities would greatly aid the ship's defensive qualities. Thus, the main belt armour would normally taper to a lesser thickness along the side of the hull towards bow and stern; it might also taper up from the central citadel towards the superstructure. The main armament and the magazines were protected by projections of thick armour from the main belt. The beginning of the pre-dreadnought era
12201-528: The first shell guns firing explosive shells were introduced following their development by the French Général Henri-Joseph Paixhans . By the 1840s they were part of the standard armament for naval powers including the French Navy , Royal Navy , Imperial Russian Navy and United States Navy . It is often held that the power of explosive shells to smash wooden hulls, as demonstrated by the Russian destruction of an Ottoman squadron at
12348-404: The first half of the 19th century. According to naval historian J. Richard Hill : "The (ironclad) had three chief characteristics: a metal-skinned hull, steam propulsion and a main armament of guns capable of firing explosive shells. It is only when all three characteristics are present that a fighting ship can properly be called an ironclad." Each of these developments was introduced separately in
12495-624: The first ironclad to enter combat, when she fought Union warships on the Mississippi during the Battle of the Head of Passes . She had been converted from a commercial vessel in New Orleans for river and coastal fighting. In February 1862, the larger CSS Virginia joined the Confederate Navy, having been rebuilt at Norfolk . Constructed on the hull of USS Merrimack , Virginia originally
12642-434: The gun, a lengthy process particularly if the gun then needed to be re-aimed. Warrior ' s Armstrong guns also had the virtue of being lighter than an equivalent smoothbore and, because of their rifling, more accurate. Nonetheless, the design was rejected because of problems which plagued breech-loaders for decades. The weakness of the breech-loader was the obvious problem of sealing the breech. All guns are powered by
12789-586: The heaviest calibers of gun ever used at sea. HMS Benbow carried two 16.25-inch (413 mm) breech-loading guns , each weighing 110 long tons (112 t). A few years afterwards, the Italians used 450 mm (17.72 inch) muzzle-loading guns on the Duilio class ships. One consideration which became more acute was that even from the original Armstrong models, following the Crimean War, range and hitting power far exceeded simple accuracy, especially at sea where
12936-413: The insides of the barrel, allowing guns to last longer and to be manufactured to tighter tolerances. The development of smokeless powder , based on nitroglycerine or nitrocellulose, by the French inventor Paul Vielle in 1884 was a further step allowing smaller charges of propellant with longer barrels. The guns of the pre-Dreadnought battleships of the 1890s tended to be smaller in caliber compared to
13083-539: The intermediate battery concept in the Indiana , Iowa , and Kearsarge classes, but not in the battleships laid down between 1897 and 1901. Shortly after the USN re-adopted the intermediate battery, the British, Italian, Russian, French, and Japanese navies laid down intermediate-battery ships. Almost all of this later generation of intermediate-battery ships finished building after Dreadnought , and hence were obsolescent before completion. The pre-dreadnought's armament
13230-464: The introduction of ironclad warships in the early 1860s, naval designers grappled with the problem of mounting heavy guns in the most efficient way possible, beginning with broadside box batteries and quickly moving to rotating gun turrets , since these afforded the ability to fire directly ahead, which was deemed important due to the adoption of ramming tactic after the Battle of Lissa in 1866. But early turrets were very heavy, which necessitated
13377-451: The late 1880s, all three systems were replaced with a hybrid barbette-turret system that combined the benefits of both types. The armoured vertical tube that supported the new gun mount was referred to as a barbette. Guns with restricted arcs of fire mounted in heavy bombers during World War II—such those in the tail of the aircraft, as opposed to fully revolving turrets—were also sometimes referred to as having barbette mounts, though usage of
13524-536: The late 1880s, for instance the Royal Sovereign class, were armoured with iron and steel compound armour. This was soon replaced with more effective case-hardened steel armour made using the Harvey process developed in the United States. First tested in 1891, Harvey armour was commonplace in ships laid down from 1893 to 1895. However, its reign was brief; in 1895, the German Kaiser Friedrich III pioneered
13671-491: The late 1880s, the British Royal Navy adopted a new mounting that combined the benefits of both kinds of mounts in the Majestic class . A heavily armoured, rotating gun house was added to the revolving platform, which kept the guns and their crews protected. The gun house was smaller and lighter than the old-style turrets, which still permitted placement higher in the ship and the corresponding benefits to stability and seakeeping. This innovation gradually became known simply as
13818-405: The latter was torpedoed and sunk by a British submarine in 1915. A squadron of German pre-dreadnoughts was present at the Battle of Jutland in 1916; German sailors called them the "five-minute ships", which was the amount of time they were expected to survive in a pitched battle. In spite of their limitations, the pre-dreadnought squadron played a useful role. As the German fleet disengaged from
13965-445: The line, but was determined that the first British ironclad would outmatch the French ships in every respect, particularly speed. A fast ship would have the advantage of being able to choose a range of engagement that could make her invulnerable to enemy fire. The British specification was more a large, powerful frigate than a ship-of-the-line. The requirement for speed meant a very long vessel, which had to be built from iron. The result
14112-399: The main belt, which ran from just below the waterline to some distance above it. This "central citadel" was intended to protect the engines from even the most powerful shells. Yet the emergence of the quick-firing gun and high explosives in the 1880s meant that the 1870s to early 1880s concept of the pure central citadel was also inadequate in the 1890s and that thinner armour extensions towards
14259-468: The main fleet and sent to the other side of the world to deal with them. Instead the British dispatched a pre-dreadnought of 1896 vintage, HMS Canopus . Intended to stiffen the British cruisers in the area, in fact her slow speed meant that she was left behind at the disastrous Battle of Coronel . Canopus redeemed herself at the Battle of the Falkland Islands , but only when grounded to act as
14406-399: The main naval armament by the ram. Those who noted the tiny number of ships that had actually been sunk by ramming struggled to be heard. The revival of ramming had a significant effect on naval tactics. Since the 17th century the predominant tactic of naval warfare had been the line of battle , where a fleet formed a long line to give it the best fire from its broadside guns. This tactic
14553-556: The melée which followed both sides were frustrated by the lack of damage inflicted by guns, and by the difficulty of ramming—nonetheless, the effective ramming attack being made by the Austrian flagship against the Italian attracted great attention in following years. The superior Italian fleet lost its two ironclads, Re d'Italia and Palestro , while the Austrian unarmored screw two-decker SMS Kaiser remarkably survived close actions with four Italian ironclads. The battle ensured
14700-549: The most from the dreadnought revolution, with four ships of the Liberté class still building when Dreadnought launched, and a further six of the Danton class begun afterwards. Germany's first pre-dreadnoughts, the Brandenburg class , were laid down in 1890. By 1905, a further 19 battleships were built or under construction, thanks to the sharp increase in naval expenditure justified by
14847-468: The most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high-seas battleships , long-range cruisers , and coastal defense ships. Rapid development of warship design in the late 19th century transformed the ironclad from a wooden-hulled vessel that carried sails to supplement its steam engines into
14994-408: The newly built Affondatore – a double-turreted ram. Opposing them, the Austrian navy had seven ironclad frigates. The Austrians believed their ships to have less effective guns than their enemy, so decided to engage the Italians at close range and ram them. The Austrian fleet formed into an arrowhead formation with the ironclads in the first line, charging at the Italian ironclad squadron. In
15141-582: The only class of turbine powered pre-dreadnought battleships, the Danton class of 1907. The pre-dreadnought battleship in its heyday was the core of a very diverse navy. Many older ironclads were still in service. Battleships served alongside cruisers of many descriptions: modern armoured cruisers which were essentially cut-down battleships, lighter protected cruisers , and even older unarmoured cruisers, sloops and frigates whether built out of steel, iron or wood. The battleships were threatened by torpedo boats; it
15288-453: The only guns heavy enough to penetrate the thick armour which protected the engines, magazines, and main guns of enemy battleships. The most common calibre for this main armament was 12-inch (305 mm), although earlier ships often had larger-calibre weapons of lower muzzle velocity (guns in the 13-inch to 14-inch range) and some designs used smaller guns because they could attain higher rates of fire. All British first-class battleships from
15435-664: The outbreak of the First Sino-Japanese War of 1894–95, which saw Japanese armoured cruisers and protected cruisers defeat the Chinese Beiyang Fleet , composed of a mixture of old ironclad battleships and cruisers, at the Battle of the Yalu River . Following their victory, and facing Russian pressure in the region, the Japanese placed orders for four more pre-dreadnoughts; along with the two Fuji s these battleships formed
15582-466: The popularity of the ram as a weapon in European ironclads for many years, and the victory won by Austria established it as the predominant naval power in the Adriatic . The battles of the American Civil War and at Lissa were very influential on the designs and tactics of the ironclad fleets that followed. In particular, it taught a generation of naval officers the (ultimately erroneous) lesson that ramming
15729-676: The pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s. In contrast to the multifarious development of ironclads in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy 's Majestic class . Built from steel, protected by compound , nickel steel or case-hardened steel armour, pre-dreadnought battleships were driven by coal -fired boilers powering compound reciprocating steam engines which turned underwater screws . These ships distinctively carried
15876-498: The ram seemed to offer the opportunity to strike a decisive blow. The scant damage inflicted by the guns of Monitor and Virginia at Hampton Roads and the spectacular but lucky success of the Austrian flagship SMS Erzherzog Ferdinand Max sinking the Italian Re d'Italia at Lissa gave strength to the ramming craze. From the early 1870s to early 1880s most British naval officers thought that guns were about to be replaced as
16023-422: The rivers, the first two of which differed from the ocean-going monitors in that they contained a paddle wheel ( USS Neosho and USS Osage ). The Union ironclads played an important role in the Mississippi and tributaries by providing tremendous fire upon Confederate forts, installations and vessels with relative impunity to enemy fire. They were not as heavily armored as the ocean-going monitors of
16170-505: The same calibre of shell. Between the Majestic class and Dreadnought , the length of the British 12-inch gun increased from 35 calibres to 45 and muzzle velocity increased from 706 metres (2,317 ft) per second to 770 metres (2,525 ft) per second. Pre-dreadnoughts also carried a secondary battery of smaller guns, typically 6-inch (152 mm), though calibres from 4 to 9.4 inches (102 to 240 mm) were used. Virtually all secondary guns were " quick firing ", employing
16317-433: The secondary battery, was able to carry ten 12-inch (305 mm) guns rather than four. She could fire eight heavy guns broadside, as opposed to four from a pre-dreadnought; and six guns ahead, as opposed to two. The move to an "all-big-gun" design was a logical conclusion of the increasingly long engagement ranges and heavier secondary batteries of the last pre-dreadnoughts; Japan and the United States had designed ships with
16464-421: The ships of the 1880s, most often 12 in (305 mm), but progressively grew in length of barrel, making use of improved propellants to gain greater muzzle velocity. The nature of the projectiles also changed during the ironclad period. Initially, the best armor-piercing projectile was a solid cast-iron shot. Later, shot of chilled iron , a harder iron alloy, gave better armor-piercing qualities. Eventually
16611-413: The ships which followed carrying two 12-inch and two 10.8-inch guns in single turrets. The Charlemagne class, laid down 1894–1896, were the first to adopt the standard four 12-inch (305 mm) gun heavy armament. The Jeune École retained a strong influence on French naval strategy, and by the end of the 19th century France had abandoned competition with Britain in battleship numbers. The French suffered
16758-518: The slightest roll or pitch of the vessel as 'floating weapons-platform' could negate the advantage of rifling. American ordnance experts accordingly preferred smoothbore monsters whose round shot could at least 'skip' along the surface of the water. Actual effective combat ranges, they had learned during the Civil War, were comparable to those in the Age of Sail—though a vessel could now be smashed to pieces in only
16905-449: The smaller USS Galena . The first battle between ironclads happened on 9 March 1862, as the armored Monitor was deployed to protect the Union's wooden fleet from the ironclad ram Virginia and other Confederate warships. In this engagement, the second day of the Battle of Hampton Roads , the two ironclads tried to ram one another while shells bounced off their armor. The battle attracted attention worldwide, making it clear that
17052-453: The steel-built, turreted battleships, and cruisers familiar in the 20th century. This change was pushed forward by the development of heavier naval guns, more sophisticated steam engines, and advances in ferrous metallurgy that made steel shipbuilding possible. The quick pace of change meant that many ships were obsolete almost as soon as they were finished and that naval tactics were in a state of flux. Many ironclads were built to make use of
17199-634: The superior Krupp armour . Europe adopted Krupp plate within five years, and only the United States persisted in using Harvey steel into the 20th century. The improving quality of armour plate meant that new ships could have better protection from a thinner and lighter armour belt; 12 inches (305 mm) of compound armour provided the same protection as just 7.5 inches (190 mm) of Harvey or 5.75 inches (133 mm) of Krupp. Almost all pre-dreadnoughts were powered by reciprocating steam engines . Most were capable of top speeds between 16 and 18 knots (21 mph; 33 km/h). The ironclads of
17346-405: The term is primarily restricted to British publications. American authors generally refer to such mounts as tail guns or as tail gun turrets. The use of barbette mountings originated in ground fortifications. The term originally referred to a raised platform on a rampart for one or more guns, enabling them to be fired over a parapet . This gave rise to the phrase en barbette , which referred to
17493-418: The tests partially confirmed this belief. What was ignored was that 14 inches (356 mm) of wood backing the iron would stop most of the splinters from penetrating and that relatively thin plates of iron backed by the same thickness of wood would generally cause shells to split open and fail to detonate. One factor in the performance of wrought iron during these tests that was not understood by metallurgists of
17640-455: The time all nations expected, hence they were jealously guarded against the risk of damage by mines or submarine attack, and kept close to home as much as possible. The obsolescence and consequent expendability of the pre-dreadnoughts meant that they could be deployed into more dangerous situations and more far-flung areas. During World War I, a large number of pre-dreadnoughts remained in service. The advances in machinery and armament meant that
17787-449: The twin-screw arrangements preferred by most other navies. Coal was the almost exclusive fuel for the pre-dreadnought period, though navies made the first experiments with oil propulsion in the late 1890s. An extra knot or two of speed could be gained for short bursts by applying a 'forced draught' to the furnaces, where air was pumped into the furnaces, but this risked damage to the boilers if used for prolonged periods. The French built
17934-484: The two following classes and returned to 11-inch guns with the Braunschweig class . While the calibre of the main battery remained generally constant, the performance of the guns improved as longer barrels were introduced. The introduction of slow-burning nitrocellulose and cordite propellant allowed the employment of a longer barrel, and therefore higher muzzle velocity —giving greater range and penetrating power for
18081-455: The two largest other navies combined; at the time, this meant France and Russia, which became formally allied in the early 1890s. The Royal Sovereign and Majestic classes were followed by a regular programme of construction at a much quicker pace than in previous years. The Canopus , Formidable , Duncan and King Edward VII classes appeared in rapid succession from 1897 to 1905. Counting two ships ordered by Chile but taken over by
18228-742: The use of cordite propellant, were lighter and more powerful than the previous guns of larger calibre. The Majestic s provided the model for battleship building in the Royal Navy and many other navies for years to come. Pre-dreadnoughts carried guns of several different calibres, for different roles in ship-to-ship combat. Very few pre-dreadnoughts deviated from what became the classic arrangement of heavy weaponry: A main battery of four heavy guns mounted in two centre-line gunhouses fore and aft (these could be either fully enclosed barbettes or true turrets but, regardless of type, were later to be universally referred to as 'turrets'). These main guns were slow-firing, and initially of limited accuracy; but they were
18375-460: The waterline. By the pre-dreadnought era the torpedo was typically 18-inch (457 mm) in diameter and had an effective range of several thousand metres. However, it was virtually unknown for a battleship to score a hit with a torpedo. During the ironclad age, the range of engagements increased; in the Sino-Japanese War of 1894–95 battles were fought at around 1 mile (1.6 km), while in
18522-428: The weapon and can also endanger the gun crew. Warrior ' s Armstrong guns suffered from both problems; the shells were unable to penetrate the 4.5-inch (114 mm) armor of Gloire , while sometimes the screw which closed the breech flew backwards out of the gun on firing. Similar problems were experienced with the breech-loading guns which became standard in the French and German navies. These problems influenced
18669-554: The western front, the Union built a formidable force of river ironclads, beginning with several converted riverboats and then contracting engineer James Eads of St. Louis , Missouri to build the City-class ironclads. These excellent ships were built with twin engines and a central paddle wheel, all protected by an armored casemate. They had a shallow draft, allowing them to journey up smaller tributaries, and were very well suited for river operations. Eads also produced monitors for use on
18816-556: The wooden warship was now out of date, with the ironclads destroying them easily. The Civil War saw more ironclads built by both sides, and they played an increasing role in the naval war alongside the unarmored warships, commerce raiders and blockade runners. The Union built a large fleet of fifty monitors modeled on their namesake. The Confederacy built ships designed as smaller versions of Virginia , many of which saw action, but their attempts to buy ironclads overseas were frustrated as European nations confiscated ships being built for
18963-617: The working of her guns. Navies worldwide continued to build masted, turretless battleships which had sufficient freeboard and were seaworthy enough to fight on the high seas. The distinction between coast-assault battleship and cruising battleship became blurred with the Admiral-class ironclads , ordered in 1880. These ships reflected developments in ironclad design, being protected by iron-and-steel compound armour rather than wrought iron . Equipped with breech-loading guns of between 12-inch and 16 ¼-inch (305 mm and 413 mm) calibre,
19110-594: Was a conventional warship made of wood, but she was converted into an iron-covered casemate ironclad gunship, when she entered the Confederate Navy . By this time, the Union had completed seven ironclad gunboats of the City class , and was about to complete USS Monitor , an innovative design proposed by the Swedish inventor John Ericsson . The Union was also building a large armored frigate, USS New Ironsides , and
19257-562: Was affirmed by British, French and German navies in subsidiary theatres of war. The German navy used its pre-dreadnoughts frequently in the Baltic campaign. However, the largest number of pre-dreadnoughts was engaged at the Gallipoli campaign. Twelve British and French pre-dreadnoughts formed the bulk of the force which attempted to " force the Dardanelles " in March 1915. The role of the pre-dreadnoughts
19404-467: Was armed as a conventional ship-of-the-line, but her steam engines could give her a speed of 12 knots (22 km/h; 14 mph), regardless of the wind conditions: a potentially decisive advantage in a naval engagement. The introduction of the steam ship-of-the-line led to a building competition between France and Britain. Eight sister ships to Napoléon were built in France over a period of ten years, but
19551-565: Was briefly taken over by Romania at the end of the mutiny. However, she was soon recovered and recommissioned as Panteleimon . After the war, Russia completed four more pre-dreadnoughts after 1905. Between 1893 and 1904, Italy laid down eight battleships; the later two classes of ship were remarkably fast, though the Regina Margherita class was poorly protected and the Regina Elena class lightly armed. In some ways, these ships presaged
19698-411: Was completed by a tertiary battery of light, rapid-fire guns, of any calibre from 3-inch (76 mm) down to machine guns . Their role was to give short-range protection against torpedo boats, or to attack the deck and superstructure of a battleship. In addition to their gun armament, many pre-dreadnought battleships were armed with torpedoes , fired from fixed tubes located either just above or below
19845-616: Was decided by the two Invincible -class battlecruisers which had been dispatched after Coronel. In the Black Sea five Russian pre-dreadnoughts saw brief action against the Ottoman battlecruiser Yavuz Sultan Selim during the Battle of Cape Sarych in November 1914. Two of the Russian pre-dreadnoughts briefly engaged Yavus Sultan Selim again in May 1915. The principle that disposable pre-dreadnoughts could be used where no modern ship could be risked
19992-410: Was during the pre-dreadnought era that the first destroyers were constructed to deal with the torpedo-boat threat, though at the same time the first effective submarines were being constructed. The pre-dreadnought age saw the beginning of the end of the 19th century naval balance of power in which France and Russia vied for competition against the massive Royal Navy , and saw the start of the rise of
20139-479: Was intended for the use of the command staff during battle. This was protected by a vertical, full height, ring of armour nearly equivalent in thickness to the main battery gunhouses and provided with observation slits. A narrow armoured tube extended down below this to the citadel; this contained & protected the various voice-tubes used for communication from the CT to various key stations during battle. The battleships of
20286-451: Was launched in 1868, followed in 1871 by HMS Devastation , a turreted ironclad which more resembled a pre-dreadnought than the previous, and its contemporary, turretless ironclads. Both ships dispensed with masts and carried four heavy guns in two turrets fore and aft. Devastation was the first ocean-worthy breastwork monitor; because of her very low freeboard , her decks were subject to being swept by water and spray, interfering with
20433-417: Was marked by a move from mounting the main armament in open barbettes to an all-enclosed, turret mounting. The deck was typically lightly armoured with 2 to 4 inches of steel. This lighter armour was to prevent high-explosive shells from wrecking the superstructure of the ship. The majority of battleships during this period of construction were fitted with a heavily-armoured conning tower, or CT, which
20580-463: Was more susceptible to fouling by marine life. By 1862, navies across Europe had adopted ironclads. Britain and France each had sixteen either completed or under construction, though the British vessels were larger. Austria, Italy, Russia, and Spain were also building ironclads. However, the first battles using the new ironclad ships took place during the American Civil War, between Union and Confederate ships in 1862. These were markedly different from
20727-450: Was propelled by a steam engine, driving a single screw propeller for a speed of 13 knots (24 km/h; 15 mph). She was armed with thirty-six 6.4-inch (160 mm) rifled guns. France proceeded to construct 16 ironclad warships, including two sister ships to Gloire , and the only two-decked broadside ironclads ever built, Magenta and Solférino . The Royal Navy had not been keen to sacrifice its advantage in steam ships of
20874-409: Was swayed by an explosion on board HMS Thunderer caused by a gun being double-loaded, a problem which could only happen with a muzzle-loading gun. The caliber and weight of guns could only increase so far. The larger the gun, the slower it would be to load, the greater the stresses on the ship's hull, and the less the stability of the ship. The size of the gun peaked in the 1880s, with some of
21021-418: Was the best way to sink enemy ironclads. The adoption of iron armor meant that the traditional naval armament of dozens of light cannon became useless, since their shot would bounce off an armored hull. To penetrate armor, increasingly heavy guns were mounted on ships; nevertheless, the view that ramming was the only way to sink an ironclad became widespread. The increasing size and weight of guns also meant
21168-427: Was the construction of two Warrior -class ironclads; HMS Warrior and HMS Black Prince . The ships had a successful design, though there were necessarily compromises between 'sea-keeping', strategic range and armor protection. Their weapons were more effective than those of Gloire , and with the largest set of steam engines yet fitted to a ship, they could steam at 14.3 knots (26.5 km/h). Yet
21315-475: Was the point at which the ships that had been laid down before were redesignated "pre-dreadnoughts". The pre-dreadnought developed from the ironclad battleship . The first ironclads—the French Gloire and HMS Warrior —looked much like sailing frigates , with three tall masts and broadside batteries, when they were commissioned in the early 1860s. HMVS Cerberus , the first breastwork monitor ,
21462-446: Was to support the brand-new dreadnought HMS Queen Elizabeth engaging the Turkish shore defences. Three of the pre-dreadnoughts were sunk by mines, and several more badly damaged. However, it was not the damage to the pre-dreadnoughts which led to the operation being called off. The two battlecruisers were also damaged; since Queen Elizabeth could not be risked in the minefield, and the pre-dreadnoughts would be unable to deal with
21609-423: Was totally unsuited to ramming, and the ram threw fleet tactics into disarray. The question of how an ironclad fleet should deploy in battle to make best use of the ram was never tested in battle, and if it had been, combat might have shown that rams could only be used against ships which were already stopped dead in the water. The ram finally fell out of favor in the 1880s, as the same effect could be achieved with
