153-534: Battleship Row was the grouping of seven U.S. battleships in port at Pearl Harbor, Hawaii , when the Japanese attacked on 7 December 1941. These ships bore the brunt of the Japanese assault. They were moored next to Ford Island when the attack commenced. The ships were Arizona , California , Maryland , Nevada , Oklahoma , Tennessee , and West Virginia . A repair ship (former coal ship), Vestal ,

306-506: A major intimidation factor for power projection in both diplomacy and military strategy . A global arms race in battleship construction began in Europe in the 1890s and culminated at the decisive Battle of Tsushima in 1905, the outcome of which significantly influenced the design of HMS Dreadnought . The launch of Dreadnought in 1906 commenced a new naval arms race. Three major fleet actions between steel battleships took place:

459-503: A British victory. The German strategy was therefore to try to provoke an engagement on their terms: either to induce a part of the Grand Fleet to enter battle alone, or to fight a pitched battle near the German coastline, where friendly minefields, torpedo-boats and submarines could be used to even the odds. This did not happen, however, due in large part to the necessity to keep submarines for

612-441: A battleship armed with twelve 11-or-12-inch (279 or 305 mm) guns hexagonally arranged would be equal to three or more of the conventional type." The Royal Navy was thinking along similar lines. A design had been circulated in 1902–1903 for "a powerful 'all big-gun' armament of two calibres, viz. four 12-inch (305 mm) and twelve 9.2-inch (234 mm) guns." The Admiralty decided to build three more King Edward VII s (with

765-478: A concern of those working on all-big-gun designs. Nevertheless, the likelihood of engagements at longer ranges was important in deciding that the heaviest possible guns should become standard, hence 12-inch rather than 10-inch. The newer designs of 12-inch gun mounting had a considerably higher rate of fire, removing the advantage previously enjoyed by smaller calibres. In 1895, a 12-inch gun might have fired one round every four minutes; by 1902, two rounds per minute

918-660: A crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany . Dreadnought races sprang up around the world, including in South America , lasting up to the beginning of World War I . Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era. Within five years, new battleships outclassed Dreadnought herself. These more powerful vessels were known as " super-dreadnoughts ". Most of

1071-556: A dangerous explosion if hit by enemy fire. And in fact, the only documented instance of one battleship successfully torpedoing another came during the action of 27 May 1941 , where the British battleship HMS  Rodney claimed to have torpedoed the crippled Bismarck at close range. The effectiveness of the guns depended in part on the layout of the turrets. Dreadnought , and the British ships which immediately followed it, carried five turrets: one forward, one aft and one amidships on

1224-429: A forward magazine breaking the hull in two. Of the other four battleships, Nevada suffered damage sufficient to keep her non-operational until late 1942; Tennessee and Maryland , although damaged, returned to service in early 1942. Pennsylvania was in dry dock , making attack difficult, and, as a result, was relatively undamaged. Vestal was also damaged. Battleship Row was not visible from Hickam Field because of

1377-503: A general fleet engagement, so it was necessary for the secondary armament to be protected against shell splinters from heavy guns, and the blast of the main armament. This philosophy of secondary armament was adopted by the German navy from the start; Nassau , for instance, carried twelve 5.9 in (150 mm) and sixteen 3.5 in (88 mm) guns, and subsequent German dreadnought classes followed this lead. These heavier guns tended to be mounted in armoured barbettes or casemates on

1530-422: A hit on an enemy dreadnought's sensitive fire control systems. It was also felt that the secondary armament could play an important role in driving off enemy cruisers from attacking a crippled battleship. The secondary armament of dreadnoughts was, on the whole, unsatisfactory. A hit from a light gun could not be relied on to stop a destroyer. Heavier guns could not be relied on to hit a destroyer, as experience at

1683-629: A large armored warship of 17,000 tons, armed solely with a single calibre main battery (twelve 12-inch [305 mm] guns), carrying 300-millimetre (12 in) belt armor , and capable of 24 knots (44 km/h). The Russo-Japanese War provided operational experience to validate the "all-big-gun" concept. During the Battle of the Yellow Sea on August 10, 1904, Admiral Togo of the Imperial Japanese Navy commenced deliberate 12-inch gun fire at

1836-585: A large block superstructure nicknamed the "Queen Anne's castle", such as in Queen Elizabeth and Warspite , which would be used in the new conning towers of the King George V -class fast battleships . External bulges were added to improve both buoyancy to counteract weight increase and provide underwater protection against mines and torpedoes. The Japanese rebuilt all of their battleships, plus their battlecruisers, with distinctive " pagoda " structures, though

1989-433: A larger part of the ship; for the first dreadnoughts, when high-explosive shellfire was still considered a significant threat, this was useful. It tended to result in the main belt being very short, only protecting a thin strip above the waterline; some navies found that when their dreadnoughts were heavily laden, the armoured belt was entirely submerged. The alternative was an "all or nothing" protection scheme , developed by

2142-399: A lighter calibre than the equivalent British ships, e.g. 12-inch calibre when the British standard was 13.5-inch (343 mm). Because German metallurgy was superior, the German 12-inch gun had better shell weight and muzzle velocity than the British 12-inch; and German ships could afford more armour for the same vessel weight because the German 12-inch guns were lighter than the 13.5-inch guns

2295-607: A limit of 35,000 tons on the displacement of capital ships. In subsequent years treaty battleships were commissioned to build up to this limit. Japan's decision to leave the Treaty in the 1930s, and the arrival of the Second World War, eventually made this limit irrelevant. Dreadnoughts mounted a uniform main battery of heavy-calibre guns; the number, size, and arrangement differed between designs. Dreadnought mounted ten 12-inch guns. 12-inch guns had been standard for most navies in

2448-575: A mine laid by a German U-boat in October 1914 and sank. The threat that German U-boats posed to British dreadnoughts was enough to cause the Royal Navy to change their strategy and tactics in the North Sea to reduce the risk of U-boat attack. Further near-misses from submarine attacks on battleships and casualties amongst cruisers led to growing concern in the Royal Navy about the vulnerability of battleships. As

2601-483: A mine laid by friendly forces, and sank with little loss of life. In May 1937, Jaime I was damaged by Nationalist air attacks and a grounding incident. The ship was forced to go back to port to be repaired. There she was again hit by several aerial bombs. It was then decided to tow the battleship to a more secure port, but during the transport she suffered an internal explosion that caused 300 deaths and her total loss. Several Italian and German capital ships participated in

2754-438: A minute at any torpedo boat making an attack. The South Carolina s and other early American dreadnoughts were similarly equipped. At this stage, torpedo boats were expected to attack separately from any fleet actions. Therefore, there was no need to armour the secondary gun armament, or to protect the crews from the blast effects of the main guns. In this context, the light guns tended to be mounted in unarmoured positions high on

2907-562: A mixed-caliber secondary battery amidships around the superstructure. An early design with superficial similarity to the pre-dreadnought is the British Devastation class of 1871. The slow-firing 12-inch (305 mm) main guns were the principal weapons for battleship-to-battleship combat. The intermediate and secondary batteries had two roles. Against major ships, it was thought a 'hail of fire' from quick-firing secondary weapons could distract enemy gun crews by inflicting damage to

3060-542: A mixture of 12-inch, 9.2-inch and 6-inch) in the 1903–1904 naval construction programme instead. The all-big-gun concept was revived for the 1904–1905 programme, the Lord Nelson class. Restrictions on length and beam meant the midships 9.2-inch turrets became single instead of twin, thus giving an armament of four 12-inch, ten 9.2-inch and no 6-inch. The constructor for this design, J. H. Narbeth , submitted an alternative drawing showing an armament of twelve 12-inch guns, but

3213-450: A number of 12-pound (3-inch, 76 mm) quick-firing guns for use against destroyers and torpedo-boats. Her armor was heavy enough for her to go head-to-head with any other ship in a gun battle, and conceivably win. Dreadnought was to have been followed by three Invincible -class battlecruisers, their construction delayed to allow lessons from Dreadnought to be used in their design. While Fisher may have intended Dreadnought to be

3366-549: A paper to President Theodore Roosevelt in December 1902 arguing the case for larger battleships. In an appendix to his paper, Poundstone suggested a greater number of 11-and-9-inch (279 and 229 mm) guns was preferable to a smaller number of 12-and-9-inch (305 and 229 mm). The Naval War College and Bureau of Construction and Repair developed these ideas in studies between 1903 and 1905. War-game studies begun in July 1903 "showed that

3519-399: A parallel course. This was also a carry-over from the older tactical doctrine of continuously closing range with the enemy, and the idea that gunfire alone may be sufficient to cripple a battleship, but not sink it outright, so a coup de grace would be made with torpedoes. In practice, torpedoes fired from battleships scored very few hits, and there was a risk that a stored torpedo would cause

3672-599: A part in major engagements in Atlantic, Pacific and Mediterranean theaters; in the Atlantic, the Germans used their battleships as independent commerce raiders. However, clashes between battleships were of little strategic importance. The Battle of the Atlantic was fought between destroyers and submarines, and most of the decisive fleet clashes of the Pacific war were determined by aircraft carriers . Dreadnought The dreadnought

3825-463: A range of 7,000 to 8,000 yards (6,400 to 7,300 m). The range of light and medium-calibre guns was limited, and accuracy declined badly at longer range. At longer ranges the advantage of a high rate of fire decreased; accurate shooting depended on spotting the shell-splashes of the previous salvo, which limited the optimum rate of fire. On 10 August 1904 the Imperial Russian Navy and

3978-474: A relatively flat trajectory, and a shell would have to hit at or just about the waterline to damage the vitals of the ship. For this reason, the early dreadnoughts' armour was concentrated in a thick belt around the waterline; this was 11 inches (280 mm) thick in Dreadnought . Behind this belt were arranged the ship's coal bunkers, to further protect the engineering spaces. In an engagement of this sort, there

4131-428: A result of pressure from Admiral Sir John ("Jackie") Fisher , HMS Dreadnought rendered existing battleships obsolete. Combining an "all-big-gun" armament of ten 12-inch (305 mm) guns with unprecedented speed (from steam turbine engines) and protection, she prompted navies worldwide to re-evaluate their battleship building programs. While the Japanese had laid down an all-big-gun battleship, Satsuma , in 1904 and

4284-571: A return to four 12-inch guns with sixteen or eighteen of 9.2-inch. After a full evaluation of reports of the action at Tsushima compiled by an official observer, Captain Pakenham , the Committee settled on a main battery of ten 12-inch guns, along with twenty-two 12-pounders as secondary armament. The committee also gave Dreadnought steam turbine propulsion, which was unprecedented in a large warship. The greater power and lighter weight of turbines meant

4437-421: A revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS Dreadnought , were referred to as " dreadnoughts ", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships dominated naval warfare in the late 19th and early 20th centuries, and were a symbol of naval dominance and national might, and for decades were

4590-474: A similar design in the Bellerophon and St. Vincent classes . An American design, South Carolina , authorized in 1905 and laid down in December 1906, was another of the first dreadnoughts, but she and her sister, Michigan , were not launched until 1908. Both used triple-expansion engines and had a superior layout of the main battery, dispensing with Dreadnought ' s wing turrets. They thus retained

4743-421: A turret. One solution to the problem of turret layout was to put three or even four guns in each turret. Fewer turrets meant the ship could be shorter, or could devote more space to machinery. On the other hand, it meant that in the event of an enemy shell destroying one turret, a higher proportion of the main armament would be out of action. The risk of the blast waves from each gun barrel interfering with others in

4896-617: A war scare with France and the build-up of the Russian navy gave added impetus to naval construction, and the British Naval Defence Act of 1889 laid down a new fleet including eight new battleships. The principle that Britain's navy should be more powerful than the two next most powerful fleets combined was established. This policy was designed to deter France and Russia from building more battleships, but both nations nevertheless expanded their fleets with more and better pre-dreadnoughts in

5049-434: Is evidence Hitler wanted calibres as high as 24-inch (609 mm); the Japanese ' Super Yamato ' design also called for 20-inch guns. None of these proposals went further than very preliminary design work. The first dreadnoughts tended to have a very light secondary armament intended to protect them from torpedo boats . Dreadnought carried 12-pounder guns; each of her twenty-two 12-pounders could fire at least 15 rounds

5202-574: The Hiei received a more modern bridge tower that would influence the new Yamato class . Bulges were fitted, including steel tube arrays to improve both underwater and vertical protection along the waterline. The U.S. experimented with cage masts and later tripod masts , though after the Japanese attack on Pearl Harbor some of the most severely damaged ships (such as West Virginia and California ) were rebuilt with tower masts, for an appearance similar to their Iowa -class contemporaries. Radar, which

5355-714: The King George V class . It was in the Mediterranean that navies remained most committed to battleship warfare. France intended to build six battleships of the Dunkerque and Richelieu classes , and the Italians four Littorio -class ships. Neither navy built significant aircraft carriers. The U.S. preferred to spend limited funds on aircraft carriers until the South Dakota class . Japan, also prioritising aircraft carriers, nevertheless began work on three mammoth Yamato s (although

5508-514: The Regia Marina —was to make use of the high rate of fire of new 12-inch guns to produce devastating rapid fire from heavy guns to replace the 'hail of fire' from lighter weapons. Something similar lay behind the Japanese move towards heavier guns; at Tsushima , Japanese shells contained a higher than normal proportion of high explosive, and were fused to explode on contact, starting fires rather than piercing armour. The increased rate of fire laid

5661-533: The Crimean War , six line-of-battle ships and two frigates of the Russian Black Sea Fleet destroyed seven Turkish frigates and three corvettes with explosive shells at the Battle of Sinop in 1853. Later in the war, French ironclad floating batteries used similar weapons against the defenses at the Battle of Kinburn . Nevertheless, wooden-hulled ships stood up comparatively well to shells, as shown in

5814-839: The First Geneva Naval Conference (1927), the First London Naval Treaty (1930), the Second Geneva Naval Conference (1932), and finally the Second London Naval Treaty (1936), which all set limits on major warships. These treaties became effectively obsolete on September 1, 1939, at the beginning of World War II , but the ship classifications that had been agreed upon still apply. The treaty limitations meant that fewer new battleships were launched in 1919–1939 than in 1905–1914. The treaties also inhibited development by imposing upper limits on

5967-603: The Royal Navy was able to use her imposing battleship and battlecruiser fleet to impose a strict and successful naval blockade of Germany and kept Germany's smaller battleship fleet bottled up in the North Sea : only narrow channels led to the Atlantic Ocean and these were guarded by British forces. Both sides were aware that, because of the greater number of British dreadnoughts, a full fleet engagement would be likely to result in

6120-401: The Royal Navy , anxious to prevent France from gaining a technological lead. The superior armored frigate Warrior followed Gloire by only 14 months, and both nations embarked on a program of building new ironclads and converting existing screw ships of the line to armored frigates. Within two years, Italy, Austria, Spain and Russia had all ordered ironclad warships, and by the time of

6273-469: The Russo-Japanese War of 1904–1905 showed that future naval battles could, and likely would, be fought at long distances. The newest 12-inch (305 mm) guns had longer range and fired heavier shells than a gun of 10-or-9.2-inch (254 or 234 mm) calibre. Another possible advantage was fire control; at long ranges guns were aimed by observing the splashes caused by shells fired in salvoes, and it

6426-570: The aircraft carrier replacing the battleship as the leading capital ship during World War II, with the last battleship to be launched being HMS  Vanguard in 1944. Four battleships were retained by the United States Navy until the end of the Cold War for fire support purposes and were last used in combat during the Gulf War in 1991, and then struck from the U.S. Naval Vessel Register in

6579-427: The invasion of Normandy . All six were decommissioned soon after the war was over. Nevada and Pennsylvania were expended in atomic bomb tests in the Pacific. The rest were scrapped in the late 1950s. Oklahoma was eventually refloated but not repaired, and capsized and sank while being towed back to the mainland for scrapping. Arizona ' s hull remains a memorial, one of the most popular tourist attractions on

6732-508: The pre-dreadnought era , and this continued in the first generation of dreadnought battleships. The Imperial German Navy was an exception, continuing to use 11-inch guns in its first class of dreadnoughts, the Nassau class . Dreadnoughts also carried lighter weapons. Many early dreadnoughts carried a secondary armament of very light guns designed to fend off enemy torpedo boats . The calibre and weight of secondary armament tended to increase, as

6885-494: The "unsinkable" German World War I battleship SMS  Ostfriesland and the American pre-dreadnought Alabama . Although Mitchell had required "war-time conditions", the ships sunk were obsolete, stationary, defenseless and had no damage control. The sinking of Ostfriesland was accomplished by violating an agreement that would have allowed Navy engineers to examine the effects of various munitions: Mitchell's airmen disregarded

7038-461: The 1866 Battle of Lissa , where the modern Austrian steam two-decker SMS  Kaiser ranged across a confused battlefield, rammed an Italian ironclad and took 80 hits from Italian ironclads, many of which were shells, but including at least one 300-pound shot at point-blank range. Despite losing her bowsprit and her foremast, and being set on fire, she was ready for action again the very next day. The development of high-explosive shells made

7191-442: The 1890s, now known as the " pre-dreadnought ", had a main armament of four heavy guns of 12-inch (300 mm) calibre , a secondary armament of six to eighteen quick-firing guns of between 4.7-and-7.5-inch (119 and 191 mm) calibre, and other smaller weapons. This was in keeping with the prevailing theory of naval combat that battles would initially be fought at some distance, but the ships would then approach to close range for

7344-451: The 1890s. In the last years of the 19th century and the first years of the 20th, the escalation in the building of battleships became an arms race between Britain and Germany . The German naval laws of 1890 and 1898 authorized a fleet of 38 battleships, a vital threat to the balance of naval power. Britain answered with further shipbuilding, but by the end of the pre-dreadnought era, British supremacy at sea had markedly weakened. In 1883,

7497-488: The 1920s and 1930s limited the number of battleships, though technical innovation in battleship design continued. Both the Allied and Axis powers built battleships during World War II, though the increasing importance of the aircraft carrier meant that the battleship played a less important role than had been expected in that conflict. The value of the battleship has been questioned, even during their heyday. There were few of

7650-439: The 2000s. Many World War II-era American battleships survive today as museum ships . A ship of the line was a large, unarmored wooden sailing ship which mounted a battery of up to 120 smoothbore guns and carronades , which came to prominence with the adoption of line of battle tactics in the early 17th century and the end of the sailing battleship's heyday in the 1830s. From 1794, the alternative term 'line of battle ship'

7803-534: The 21-knot design speed could be achieved in a smaller and less costly ship than if reciprocating engines had been used. Construction took place quickly; the keel was laid on 2 October 1905, the ship was launched on 10 February 1906, and completed on 3 October 1906—an impressive demonstration of British industrial might. The first US dreadnoughts were the two South Carolina -class ships. Detailed plans for these were worked out in July–November 1905, and approved by

SECTION 50

7956-460: The 8-inch battery being completely unusable, and the inability to train the primary and intermediate armaments on different targets led to significant tactical limitations. Even though such innovative designs saved weight (a key reason for their inception), they proved too cumbersome in practice. In 1906, the British Royal Navy launched the revolutionary HMS  Dreadnought . Created as

8109-623: The Admiralty was not prepared to accept this. Part of the rationale for the decision to retain mixed-calibre guns was the need to begin the building of the ships quickly because of the tense situation produced by the Russo-Japanese War. The replacement of the 6-or-8-inch (152 or 203 mm) guns with weapons of 9.2-or-10-inch (234 or 254 mm) calibre improved the striking power of a battleship, particularly at longer ranges. Uniform heavy-gun armament offered many other advantages. One advantage

8262-602: The Atlantic campaign. Submarines were the only vessels in the Imperial German Navy able to break out and raid British commerce in force, but even though they sank many merchant ships, they could not successfully counter-blockade the United Kingdom; the Royal Navy successfully adopted convoy tactics to combat Germany's submarine counter-blockade and eventually defeated it. This was in stark contrast to Britain's successful blockade of Germany. The first two years of war saw

8415-458: The Battle of Jutland showed. The casemate mountings of heavier guns proved problematic; being low in the hull, they proved liable to flooding, and on several classes, some were removed and plated over. The only sure way to protect a dreadnought from destroyer or torpedo boat attack was to provide a destroyer squadron as an escort. After World War I the secondary armament tended to be mounted in turrets on

8568-488: The Board of Construction on 23 November 1905. Building was slow; specifications for bidders were issued on 21 March 1906, the contracts awarded on 21 July 1906 and the two ships were laid down in December 1906, after the completion of the Dreadnought . The designers of dreadnoughts sought to provide as much protection, speed, and firepower as possible in a ship of a realistic size and cost. The hallmark of dreadnought battleships

8721-485: The British King Edward VII and Lord Nelson ; Russian Andrei Pervozvanny ; Japanese Katori , Satsuma , and Kawachi ; American Connecticut and Mississippi ; French Danton ; Italian Regina Elena ; and Austro-Hungarian Radetzky classes . The design process for these ships often included discussion of an 'all-big-gun one-calibre' alternative. The June 1902 issue of Proceedings of

8874-547: The British and French blockade. And in the Mediterranean , the most important use of battleships was in support of the amphibious assault on Gallipoli . In September 1914, the threat posed to surface ships by German U-boats was confirmed by successful attacks on British cruisers, including the sinking of three British armored cruisers by the German submarine SM  U-9 in less than an hour. The British Super-dreadnought HMS  Audacious soon followed suit as she struck

9027-520: The British fleet. Less than two months later, the Germans once again attempted to draw portions of the Grand Fleet into battle. The resulting Action of 19 August 1916 proved inconclusive. This reinforced German determination not to engage in a fleet to fleet battle. In the other naval theatres there were no decisive pitched battles. In the Black Sea , engagement between Russian and Ottoman battleships

9180-534: The British required for comparable effect. Over time the calibre of guns tended to increase. In the Royal Navy, the Orion class, launched 1910, had ten 13.5-inch guns, all on the centreline; the Queen Elizabeth class, launched in 1913, had eight 15-inch (381 mm) guns. In all navies, fewer guns of larger calibre came to be used. The smaller number of guns simplified their distribution, and centreline turrets became

9333-613: The Dardanelles Campaign and the destruction of the Austro-Hungarian dreadnought SMS  Szent István by Italian motor torpedo boats in June 1918. In large fleet actions, however, destroyers and torpedo boats were usually unable to get close enough to the battleships to damage them. The only battleship sunk in a fleet action by either torpedo boats or destroyers was the obsolescent German pre-dreadnought SMS  Pommern . She

9486-454: The German Navy, and prevented Germany from building or possessing any capital ships . The inter-war period saw the battleship subjected to strict international limitations to prevent a costly arms race breaking out. While the victors were not limited by the Treaty of Versailles, many of the major naval powers were crippled after the war. Faced with the prospect of a naval arms race against

9639-525: The High Seas Fleet be disarmed and interned in a neutral port; largely because no neutral port could be found, the ships remained in British custody in Scapa Flow , Scotland. The Treaty of Versailles specified that the ships should be handed over to the British. Instead, most of them were scuttled by their German crews on June 21, 1919, just before the signature of the peace treaty. The treaty also limited

9792-542: The Imperial Japanese Navy had one of the longest-range gunnery duels to date—over 14,000 yd (13,000 m) during the Battle of the Yellow Sea . The Russian battleships were equipped with Lugeol range finders with an effective range of 4,400 yd (4,000 m), and the Japanese ships had Barr & Stroud range finders that reached out to 6,600 yd (6,000 m), but both sides still managed to hit each other with 12-inch (305 mm) fire at 14,000 yd (13,000 m). Naval architects and strategists around

9945-579: The Moray Firth. Whilst the escape of the German fleet from the superior British firepower at Jutland was effected by the German cruisers and destroyers successfully turning away the British battleships, the German attempt to rely on U-boat attacks on the British fleet failed. Torpedo boats did have some successes against battleships in World War I, as demonstrated by the sinking of the British pre-dreadnought HMS  Goliath by Muâvenet-i Millîye during

10098-576: The North Sea were battles including the Heligoland Bight and Dogger Bank and German raids on the English coast, all of which were attempts by the Germans to lure out portions of the Grand Fleet in an attempt to defeat the Royal Navy in detail. On May 31, 1916, a further attempt to draw British ships into battle on German terms resulted in a clash of the battlefleets in the Battle of Jutland . The German fleet withdrew to port after two short encounters with

10251-538: The Republic, killed their officers, who apparently supported Franco's attempted coup, and joined the Republican Navy. Thus each side had one battleship; however, the Republican Navy generally lacked experienced officers. The Spanish battleships mainly restricted themselves to mutual blockades, convoy escort duties, and shore bombardment, rarely in direct fighting against other surface units. In April 1937, España ran into

10404-496: The Royal Navy's battleships and battlecruisers regularly "sweep" the North Sea making sure that no German ships could get in or out. Only a few German surface ships that were already at sea, such as the famous light cruiser SMS  Emden , were able to raid commerce. Even some of those that did manage to get out were hunted down by battlecruisers, as in the Battle of the Falklands , December 7, 1914. The results of sweeping actions in

10557-453: The Russian flagship Tzesarevich at 14,200 yards (13,000 meters). At the Battle of Tsushima on May 27, 1905, Russian Admiral Rozhestvensky's flagship fired the first 12-inch guns at the Japanese flagship Mikasa at 7,000 meters. It is often held that these engagements demonstrated the importance of the 12-inch (305 mm) gun over its smaller counterparts, though some historians take the view that secondary batteries were just as important as

10710-496: The U.S. Navy's nascent aircraft carrier program. The Royal Navy , United States Navy , and Imperial Japanese Navy extensively upgraded and modernized their World War I–era battleships during the 1930s. Among the new features were an increased tower height and stability for the optical rangefinder equipment (for gunnery control), more armor (especially around turrets) to protect against plunging fire and aerial bombing, and additional anti-aircraft weapons. Some British ships received

10863-562: The US Naval Institute contained comments by the US Navy's leading gunnery expert, P. R. Alger , proposing a main battery of eight 12-inch (305 mm) guns in twin turrets. In May 1902, the Bureau of Construction and Repair submitted a design for the battleship with twelve 10-inch (254 mm) guns in twin turrets, two at the ends and four in the wings. Lt. Cdr. Homer C. Poundstone submitted

11016-569: The US Navy ordered a design of torpedo effective to 4,000 yards (3,700 m). Both British and American admirals concluded that they needed to engage the enemy at longer ranges. In 1900, Admiral Fisher, commanding the Royal Navy Mediterranean Fleet , ordered gunnery practice with 6-inch guns at 6,000 yards (5,500 m). By 1904 the US Naval War College was considering the effects on battleship tactics of torpedoes with

11169-470: The US Navy. The armour belt was tall and thick, but no side protection at all was provided to the ends of the ship or the upper decks. The armoured deck was also thickened. The "all-or-nothing" system provided more effective protection against the very-long-range engagements of dreadnought fleets and was adopted outside the US Navy after World War I. The design of the dreadnought changed to meet new challenges. For example, armour schemes were changed to reflect

11322-562: The United Kingdom and Japan, which would in turn have led to a possible Pacific war , the United States was keen to conclude the Washington Naval Treaty of 1922. This treaty limited the number and size of battleships that each major nation could possess, and required Britain to accept parity with the U.S. and to abandon the British alliance with Japan. The Washington treaty was followed by a series of other naval treaties, including

11475-683: The United Kingdom had 38 battleships, twice as many as France and almost as many as the rest of the world put together. In 1897, Britain's lead was far smaller due to competition from France, Germany, and Russia, as well as the development of pre-dreadnought fleets in Italy, the United States and Japan . The Ottoman Empire, Spain, Sweden, Denmark, Norway , the Netherlands , Chile and Brazil all had second-rate fleets led by armored cruisers , coastal defence ships or monitors . Pre-dreadnoughts continued

11628-527: The United Kingdom—meant these ships were completed with a mixture of 12-inch and 10-inch armament. The 1903–1904 design retained traditional triple-expansion steam engines , unlike Dreadnought . The dreadnought breakthrough occurred in the United Kingdom in October 1905. Fisher, now the First Sea Lord , had long been an advocate of new technology in the Royal Navy and had recently been convinced of

11781-510: The Washington Naval Treaty, as virtually all remaining battleships shared dreadnought characteristics; it can also be used to describe battlecruisers , the other type of ship resulting from the dreadnought revolution. The distinctive all-big-gun armament of the dreadnought was developed in the first years of the 20th century as navies sought to increase the range and power of the armament of their battleships. The typical battleship of

11934-425: The armour. Designers spent much time and effort to provide the best possible protection for their ships against the various weapons with which they would be faced. Only so much weight could be devoted to protection, without compromising speed, firepower or seakeeping. The bulk of a dreadnought's armour was concentrated around the "armoured citadel". This was a box, with four armoured walls and an armoured roof, around

12087-481: The barrels. The disadvantages of guns of larger calibre are that guns and turrets must be heavier; and heavier shells, which are fired at lower velocities, require turret designs that allow a larger angle of elevation for the same range. Heavier shells have the advantage of being slowed less by air resistance, retaining more penetrating power at longer ranges. Different navies approached the issue of calibre in different ways. The German navy, for instance, generally used

12240-552: The centre of gravity of the ship, and might reduce the stability of the ship. Nevertheless, this layout made the best of the firepower available from a fixed number of guns, and was eventually adopted generally. The US Navy used superfiring on the South Carolina class, and the layout was adopted in the Royal Navy with the Orion class of 1910. By World War II, superfiring was entirely standard. Initially, all dreadnoughts had two guns to

12393-525: The centreline of the ship, and two in the 'wings' next to the superstructure . This allowed three turrets to fire ahead and four on the broadside. The Nassau and Helgoland classes of German dreadnoughts adopted a 'hexagonal' layout, with one turret each fore and aft and four wing turrets; this meant more guns were mounted in total, but the same number could fire ahead or broadside as with Dreadnought . Dreadnought designs experimented with different layouts. The British Neptune -class battleship staggered

12546-407: The chance to increase range and armour penetration. Both methods offered advantages and disadvantages, though in general greater muzzle velocity meant increased barrel wear. As guns fire, their barrels wear out, losing accuracy and eventually requiring replacement. At times, this became problematic; the US Navy seriously considered stopping practice firing of heavy guns in 1910 because of the wear on

12699-499: The concept of an all-big-gun ship had been in circulation for several years, it had yet to be validated in combat. Dreadnought sparked a new arms race , principally between Britain and Germany but reflected worldwide, as the new class of warships became a crucial element of national power. Technical development continued rapidly through the dreadnought era, with steep changes in armament, armor and propulsion. Ten years after Dreadnought ' s commissioning, much more powerful ships,

12852-428: The decisive fleet battles that battleship proponents expected and used to justify the vast resources spent on building battlefleets. Even in spite of their huge firepower and protection, battleships were increasingly vulnerable to much smaller and relatively inexpensive weapons: initially the torpedo and the naval mine , and later attack aircraft and the guided missile . The growing range of naval engagements led to

13005-514: The design of HMS Dreadnought in January 1905, and she was laid down in October of the same year. Finally, the US Navy gained authorization for USS  Michigan , carrying eight 12-inch guns, in March 1905, with construction commencing in December 1906. The move to all-big-gun designs was accomplished because a uniform, heavy-calibre armament offered advantages in both firepower and fire control, and

13158-404: The development of the anti-torpedo bulge and torpedo belt , both attempts to protect against underwater damage by mines and torpedoes. The purpose of underwater protection was to absorb the force of a detonating mine or torpedo well away from the final watertight hull. This meant an inner bulkhead along the side of the hull, which was generally lightly armoured to capture splinters, separated from

13311-598: The end of World War I, aircraft had successfully adopted the torpedo as a weapon. In 1921 the Italian general and air theorist Giulio Douhet completed a hugely influential treatise on strategic bombing titled The Command of the Air , which foresaw the dominance of air power over naval units. In the 1920s, General Billy Mitchell of the United States Army Air Corps , believing that air forces had rendered navies around

13464-568: The famous clash of the USS ; Monitor and the CSS ; Virginia at the Battle of Hampton Roads at least eight navies possessed ironclad ships. Navies experimented with the positioning of guns, in turrets (like the USS Monitor ), central-batteries or barbettes , or with the ram as the principal weapon. As steam technology developed, masts were gradually removed from battleship designs. By

13617-680: The final blows (as they did in the Battle of Manila Bay ), when the shorter-range, faster-firing guns would prove most useful. Some designs had an intermediate battery of 8-inch (203 mm) guns. Serious proposals for an all-big-gun armament were circulated in several countries by 1903. All-big-gun designs commenced almost simultaneously in three navies. In 1904, the Imperial Japanese Navy authorized construction of Satsuma , originally designed with twelve 12-inch (305 mm) guns. Work began on her construction in May 1905. The Royal Navy began

13770-508: The first shots of World War II with the bombardment of the Polish garrison at Westerplatte ; and the final surrender of the Japanese Empire took place aboard a United States Navy battleship, USS  Missouri . Between those two events, it had become clear that aircraft carriers were the new principal ships of the fleet and that battleships now performed a secondary role. Battleships played

13923-407: The foundations for future advances in fire control. In Japan, the two battleships of the 1903–1904 programme were the first in the world to be laid down as all-big-gun ships, with eight 12-inch guns. The armour of their design was considered too thin, demanding a substantial redesign. The financial pressures of the Russo-Japanese War and the short supply of 12-inch guns—which had to be imported from

14076-411: The greater risk of plunging shells from long-range gunfire, and the increasing threat from armour-piercing bombs dropped by aircraft. Later designs carried a greater thickness of steel on the armoured deck; Yamato carried a 16-inch (410 mm) main belt, but a deck 9-inch (230 mm) thick. The final element of the protection scheme of the first dreadnoughts was the subdivision of the ship below

14229-429: The hull would be longer, which posed some challenges for the designers; a longer ship needed to devote more weight to armour to get equivalent protection, and the magazines which served each turret interfered with the distribution of boilers and engines. For these reasons, HMS  Agincourt , which carried a record fourteen 12-inch guns in seven centreline turrets, was not considered a success. A superfiring layout

14382-498: The idea of an all-big-gun battleship. Fisher is often credited as the creator of the dreadnought and the father of the United Kingdom's great dreadnought battleship fleet, an impression he himself did much to reinforce. It has been suggested Fisher's main focus was on the arguably even more revolutionary battlecruiser and not the battleship. Shortly after taking office, Fisher set up a Committee on Designs to consider future battleships and armoured cruisers. The committee's first task

14535-400: The island. Utah was in port at Pearl Harbor, but was not moored with the rest of the battleships, as she had since been converted to a target ship . However, she was still sunk within a few minutes of the battle. Battleship A battleship is a large, heavily armored warship with a main battery consisting of large- caliber guns , designed to serve as capital ships with

14688-481: The larger weapons when dealing with smaller fast-moving torpedo craft. Such was the case, albeit unsuccessfully, when the Russian battleship  Knyaz Suvorov at Tsushima had been sent to the bottom by destroyer -launched torpedoes. The 1903–04 design also retained traditional triple-expansion steam engines . As early as 1904, Jackie Fisher had been convinced of the need for fast, powerful ships with an all-big-gun armament. If Tsushima influenced his thinking, it

14841-412: The last Royal Navy battleship, the design was so successful he found little support for his plan to switch to a battlecruiser navy. Although there were some problems with the ship (the wing turrets had limited arcs of fire and strained the hull when firing a full broadside, and the top of the thickest armor belt lay below the waterline at full load), the Royal Navy promptly commissioned another six ships to

14994-498: The late-1930s Yamato class . Several later designs used quadruple turrets, including the British King George V class and French Richelieu class . Rather than try to fit more guns onto a ship, it was possible to increase the power of each gun. This could be done by increasing either the calibre of the weapon and hence the weight of shell, or by lengthening the barrel to increase muzzle velocity . Either of these offered

15147-579: The limit were the Japanese Yamato class, begun in 1937 (after the treaty expired), which carried 18 in (460 mm) main guns. By the middle of World War II, the United Kingdom was making use of 15 in (380 mm) guns kept as spares for the Queen Elizabeth class to arm the last British battleship, HMS  Vanguard . Some World War II-era designs were drawn up proposing another move towards gigantic armament. The German H-43 and H-44 designs proposed 20-inch (508 mm) guns, and there

15300-402: The line gradually became larger and carried more guns, but otherwise remained quite similar. The first major change to the ship of the line concept was the introduction of steam power as an auxiliary propulsion system . Steam power was gradually introduced to the navy in the first half of the 19th century, initially for small craft and later for frigates . The French Navy introduced steam to

15453-419: The line of battle with the 90-gun Napoléon in 1850 —the first true steam battleship. Napoléon was armed as a conventional ship-of-the-line, but her steam engines could give her a speed of 12 knots (22 km/h), regardless of the wind. This was a potentially decisive advantage in a naval engagement. The introduction of steam accelerated the growth in size of battleships. France and the United Kingdom were

15606-406: The line was overtaken by the ironclad : powered by steam, protected by metal armor, and armed with guns firing high-explosive shells . Guns that fired explosive or incendiary shells were a major threat to wooden ships, and these weapons quickly became widespread after the introduction of 8-inch shell guns as part of the standard armament of French and American line-of-battle ships in 1841. In

15759-492: The long-range gunnery duel at the Battle of the Yellow Sea in 1904, the decisive Battle of Tsushima in 1905 (both during the Russo-Japanese War ) and the inconclusive Battle of Jutland in 1916, during the First World War . Jutland was the largest naval battle and the only full-scale clash of dreadnoughts of the war, and it was the last major battle in naval history fought primarily by battleships. The Naval Treaties of

15912-418: The magazines for the main armament. A hit to any of these systems could cripple or destroy the ship. The "floor" of the box was the bottom of the ship's hull, and was unarmoured, although it was, in fact, a "triple bottom". The earliest dreadnoughts were intended to take part in a pitched battle against other battleships at ranges of up to 10,000 yd (9,100 m). In such an encounter, shells would fly on

16065-470: The main deck. The Royal Navy increased its secondary armament from 12-pounder to first 4-inch (100 mm) and then 6-inch (150 mm) guns, which were standard at the start of World War I; the US standardized on 5-inch calibre for the war but planned 6-inch guns for the ships designed just afterwards. The secondary battery served several other roles. It was hoped that a medium-calibre shell might be able to score

16218-415: The mid-1870s steel was used as a construction material alongside iron and wood. The French Navy's Redoutable , laid down in 1873 and launched in 1876, was a central battery and barbette warship which became the first battleship in the world to use steel as the principal building material. The term "battleship" was officially adopted by the Royal Navy in the re-classification of 1892. By the 1890s, there

16371-419: The most important parts of the ship. The sides of the citadel were the "armoured belt" of the ship, which started on the hull just in front of the forward turret and ran to just behind the aft turret. The ends of the citadel were two armoured bulkheads, fore and aft, which stretched between the ends of the armour belt. The "roof" of the citadel was an armoured deck. Within the citadel were the boilers, engines, and

16524-417: The most intense firepower . Before the rise of supercarriers , battleships were among the largest and most formidable weapon systems ever built. The term battleship came into use in the late 1880s to describe a type of ironclad warship , now referred to by historians as pre-dreadnought battleships . In 1906, the commissioning of HMS  Dreadnought into the United Kingdom 's Royal Navy heralded

16677-465: The non-intervention blockade. On May 29, 1937, two Republican aircraft managed to bomb the German pocket battleship Deutschland outside Ibiza , causing severe damage and loss of life. Admiral Scheer retaliated two days later by bombarding Almería , causing much destruction, and the resulting Deutschland incident meant the end of German and Italian participation in non-intervention. The Schleswig-Holstein —an obsolete pre-dreadnought —fired

16830-670: The norm. A further step change was planned for battleships designed and laid down at the end of World War I. The Japanese Nagato -class battleships in 1917 carried 410-millimetre (16.1 in) guns, which was quickly matched by the US Navy's Colorado class . Both the United Kingdom and Japan were planning battleships with 18-inch (457 mm) armament, in the British case the N3 class . The Washington Naval Treaty concluded on 6 February 1922 and ratified later limited battleship guns to not more than 16-inch (410 mm) calibre, and these heavier guns were not produced. The only battleships to break

16983-467: The only countries to develop fleets of wooden steam screw battleships although several other navies operated small numbers of screw battleships, including Russia (9), the Ottoman Empire (3), Sweden (2), Naples (1), Denmark (1) and Austria (1). The adoption of steam power was only one of a number of technological advances which revolutionized warship design in the 19th century. The ship of

17136-527: The original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty , but many of the newer super-dreadnoughts continued serving throughout World War II . Dreadnought-building consumed vast resources in the early 20th century, but there was only one battle between large dreadnought fleets. At the Battle of Jutland in 1916, the British and German navies clashed with no decisive result. The term dreadnought gradually dropped from use after World War I, especially after

17289-533: The range had closed to 4,300 yards (3,900 m), and most of the fighting occurred at 2,200 yards (2,000 m). At these ranges, lighter guns had good accuracy, and their high rate of fire delivered high volumes of ordnance on the target, known as the "hail of fire". Naval gunnery was too inaccurate to hit targets at a longer range. By the early 20th century, British and American admirals expected future battleships would engage at longer distances. Newer models of torpedo had longer ranges. For instance, in 1903,

17442-430: The range of the guns. Some historians today hold that a uniform calibre was particularly important because the risk of confusion between shell-splashes of 12-inch and lighter guns made accurate ranging difficult. This viewpoint is controversial, as fire control in 1905 was not advanced enough to use the salvo-firing technique where this confusion might be important, and confusion of shell-splashes does not seem to have been

17595-419: The range of torpedoes and the staying power of the torpedo boats and destroyers expected to carry them also increased. From the end of World War I onwards, battleships had to be equipped with many light guns as anti-aircraft armament. Dreadnoughts frequently carried torpedo tubes themselves. In theory, a line of battleships so equipped could unleash a devastating volley of torpedoes on an enemy line steaming

17748-470: The rules, and sank the ship within minutes in a coordinated attack. The stunt made headlines, and Mitchell declared, "No surface vessels can exist wherever air forces acting from land bases are able to attack them." While far from conclusive, Mitchell's test was significant because it put proponents of the battleship against naval aviation on the defensive. Rear Admiral William A. Moffett used public relations against Mitchell to make headway toward expansion of

17901-439: The same broadside, despite having two fewer guns. In 1897, before the revolution in design brought about by HMS  Dreadnought , the Royal Navy had 62 battleships in commission or building, a lead of 26 over France and 50 over Germany. From the 1906 launching of Dreadnought , an arms race with major strategic consequences was prompted. Major naval powers raced to build their own dreadnoughts. Possession of modern battleships

18054-756: The same turret reduced the rate of fire from the guns somewhat. The first nation to adopt the triple turret was Italy, in the Dante Alighieri , soon followed by Russia with the Gangut class , the Austro-Hungarian Tegetthoff class , and the US Nevada class . British Royal Navy battleships did not adopt triple turrets until after the First World War, with the Nelson class , and Japanese battleships not until

18207-458: The ship to minimize weight and maximize field of fire. Within a few years, the principal threat was from the destroyer—larger, more heavily armed, and harder to destroy than the torpedo boat. Since the risk from destroyers was very serious, it was considered that one shell from a battleship's secondary armament should sink (rather than merely damage) any attacking destroyer. Destroyers, in contrast to torpedo boats, were expected to attack as part of

18360-463: The shores, this coast of Ford Island became the de facto mooring location for the Pacific Fleet's battleships and took on the nickname "Battleship Row". Arizona , California , Oklahoma , and West Virginia were sunk during the attack (albeit, California and West Virginia were refloated and rejoined the fleet in 1944). Arizona suffered the most serious damage and loss of life, an explosion in

18513-472: The strategic position had changed. In Germany , the ambitious Plan Z for naval rearmament was abandoned in favor of a strategy of submarine warfare supplemented by the use of battlecruisers and commerce raiding (in particular by Bismarck -class battleships). In Britain, the most pressing need was for air defenses and convoy escorts to safeguard the civilian population from bombing or starvation, and re-armament construction plans consisted of five ships of

18666-590: The super-dreadnoughts, were being built. In the first years of the 20th century, several navies worldwide experimented with the idea of a new type of battleship with a uniform armament of very heavy guns. Admiral Vittorio Cuniberti , the Italian Navy's chief naval architect, articulated the concept of an all-big-gun battleship in 1903. When the Regia Marina did not pursue his ideas, Cuniberti wrote an article in Jane ' s proposing an "ideal" future British battleship,

18819-528: The superstructure, and they would be more effective against smaller ships such as cruisers . Smaller guns (12-pounders and smaller) were reserved for protecting the battleship against the threat of torpedo attack from destroyers and torpedo boats . The beginning of the pre-dreadnought era coincided with Britain reasserting her naval dominance. For many years previously, Britain had taken naval supremacy for granted. Expensive naval projects were criticized by political leaders of all inclinations. However, in 1888

18972-463: The superstructure, much thinner steel armour was applied to the decks of the ship. The thickest protection was reserved for the central citadel in all battleships. Some navies extended a thinner armoured belt and armoured deck to cover the ends of the ship, or extended a thinner armoured belt up the outside of the hull. This "tapered" armour was used by the major European navies—the United Kingdom, Germany, and France. This arrangement gave some armour to

19125-479: The technical innovations of the ironclad. Turrets, armor plate, and steam engines were all improved over the years, and torpedo tubes were also introduced. A small number of designs, including the American Kearsarge and Virginia classes , experimented with all or part of the 8-inch intermediate battery superimposed over the 12-inch primary. Results were poor: recoil factors and blast effects resulted in

19278-404: The thick black smoke. Following the attack, operations immediately commenced to refloat and repair the damaged ships. The first to be completed was Nevada on 19 April 1942. By the end of the war, all except Arizona and Oklahoma had returned to service. Each of the six surviving battleships saw service in the Pacific island hopping campaign . Nevada also served in the Atlantic and supported

19431-542: The third, Shinano , was later completed as a carrier) and a planned fourth was cancelled. At the outbreak of the Spanish Civil War , the Spanish navy included only two small dreadnought battleships, España and Jaime I . España (originally named Alfonso XIII ), by then in reserve at the northwestern naval base of El Ferrol , fell into Nationalist hands in July 1936. The crew aboard Jaime I remained loyal to

19584-406: The threat posed to dreadnought battleships proved to have been largely a false alarm. HMS Audacious turned out to be the only dreadnought sunk by a submarine in World War I. While battleships were never intended for anti-submarine warfare, there was one instance of a submarine being sunk by a dreadnought battleship. HMS Dreadnought rammed and sank the German submarine U-29 on March 18, 1915, off

19737-399: The upper deck and around the superstructure. This allowed a wide field of fire and good protection without the negative points of casemates. Increasingly through the 1920s and 1930s, the secondary guns were seen as a major part of the anti-aircraft battery, with high-angle, dual-purpose guns increasingly adopted. Much of the displacement of a dreadnought was taken up by the steel plating of

19890-427: The use of iron armor plate on warships necessary. In 1859 France launched Gloire , the first ocean-going ironclad warship. She had the profile of a ship of the line, cut to one deck due to weight considerations. Although made of wood and reliant on sail for most journeys, Gloire was fitted with a propeller, and her wooden hull was protected by a layer of thick iron armor. Gloire prompted further innovation from

20043-478: The war wore on however, it turned out that whilst submarines did prove to be a very dangerous threat to older pre-dreadnought battleships, as shown by examples such as the sinking of Mesûdiye , which was caught in the Dardanelles by a British submarine and HMS  Majestic and HMS  Triumph were torpedoed by U-21 as well as HMS  Formidable , HMS  Cornwallis , HMS  Britannia etc.,

20196-529: The waterline into several watertight compartments. If the hull were holed—by shellfire, mine , torpedo, or collision—then, in theory, only one area would flood and the ship could survive. To make this precaution even more effective, many dreadnoughts had no doors between different underwater sections, so that even a surprise hole below the waterline need not sink the ship. There were still several instances where flooding spread between underwater compartments. The greatest evolution in dreadnought protection came with

20349-625: The weights of ships. Designs like the projected British N3-class battleship, the first American South Dakota class , and the Japanese Kii class —all of which continued the trend to larger ships with bigger guns and thicker armor—never got off the drawing board. Those designs which were commissioned during this period were referred to as treaty battleships . As early as 1914, the British Admiral Percy Scott predicted that battleships would soon be made irrelevant by aircraft . By

20502-505: The wing turrets, so all ten guns could fire on the broadside, a feature also used by the German Kaiser class . This risked blast damage to parts of the ship over which the guns fired, and put great stress on the ship's frames. If all turrets were on the centreline of the vessel, stresses on the ship's frames were relatively low. This layout meant the entire main battery could fire on the broadside, though fewer could fire end-on. It meant

20655-468: The world obsolete, testified in front of Congress that "1,000 bombardment airplanes can be built and operated for about the price of one battleship" and that a squadron of these bombers could sink a battleship, making for more efficient use of government funds. This infuriated the U.S. Navy, but Mitchell was nevertheless allowed to conduct a careful series of bombing tests alongside Navy and Marine bombers. In 1921, he bombed and sank numerous ships, including

20808-504: The world took notice. An evolutionary step was to reduce the quick-firing secondary battery and substitute additional heavy guns, typically 9.2-to-10-inch (234 to 254 mm). Ships designed in this way have been described as 'all-big-gun mixed-calibre' or later 'semi-dreadnoughts'. Semi-dreadnought ships had many heavy secondary guns in wing turrets near the centre of the ship, instead of the small guns mounted in barbettes of earlier pre-dreadnought ships. Semi-dreadnought classes included

20961-406: Was also a lesser threat of indirect damage to the vital parts of the ship. A shell which struck above the belt armour and exploded could send fragments flying in all directions. These fragments were dangerous but could be stopped by much thinner armour than what would be necessary to stop an unexploded armour-piercing shell. To protect the innards of the ship from fragments of shells which detonated on

21114-524: Was also present, moored next to Arizona . When the United States Navy decided in 1919 to establish a major naval base in Pearl Harbor, the southeastern side of Ford Island was ceded from control of the Army Air Service at the behest of Secretary of War Newton D. Baker . Due to its location in the center of the harbor, where the water was deepest and the potential for maneuvering greater than along

21267-493: Was an "all-big-gun" armament, but they also had heavy armour concentrated mainly in a thick belt at the waterline and in one or more armoured decks. Secondary armament, fire control, command equipment, and protection against torpedoes also had to be crammed into the hull. The inevitable consequence of demands for ever greater speed, striking power, and endurance meant that displacement , and hence cost, of dreadnoughts tended to increase. The Washington Naval Treaty of 1922 imposed

21420-462: Was an increasing similarity between battleship designs, and the type that later became known as the 'pre-dreadnought battleship' emerged. These were heavily armored ships, mounting a mixed battery of guns in turrets, and without sails. The typical first-class battleship of the pre-dreadnought era displaced 15,000 to 17,000  tons , had a speed of 16 knots (30 km/h), and an armament of four 12-inch (305 mm) guns in two turrets fore and aft with

21573-430: Was contracted (informally at first) to 'battle ship' or 'battleship'. The sheer number of guns fired broadside meant a ship of the line could wreck any wooden enemy, holing her hull , knocking down masts , wrecking her rigging , and killing her crew. However, the effective range of the guns was as little as a few hundred yards, so the battle tactics of sailing ships depended in part on the wind. Over time, ships of

21726-456: Was difficult to interpret different splashes caused by different calibres of gun. There is still debate as to whether this feature was important. In naval battles of the 1890s the decisive weapon was the medium-calibre, typically 6-inch (152 mm), quick-firing gun firing at relatively short range; at the Battle of the Yalu River in 1894, the victorious Japanese did not commence firing until

21879-411: Was effective beyond visual range and effective in complete darkness or adverse weather, was introduced to supplement optical fire control. Even when war threatened again in the late 1930s, battleship construction did not regain the level of importance it had held in the years before World War I. The "building holiday" imposed by the naval treaties meant the capacity of dockyards worldwide had shrunk, and

22032-420: Was eventually adopted as standard. This involved raising one or two turrets so they could fire over a turret immediately forward or astern of them. The US Navy adopted this feature with their first dreadnoughts in 1906, but others were slower to do so. As with other layouts there were drawbacks. Initially, there were concerns about the impact of the blast of the raised guns on the lower turret. Raised turrets raised

22185-590: Was logistical simplicity. When the US was considering whether to have a mixed-calibre main armament for the South Carolina class , for example, William Sims and Poundstone stressed the advantages of homogeneity in terms of ammunition supply and the transfer of crews from the disengaged guns to replace gunners wounded in action. A uniform calibre of gun also helped streamline fire control. The designers of Dreadnought preferred an all-big-gun design because it would mean only one set of calculations about adjustments to

22338-425: Was not only seen as vital to naval power, but also, as with nuclear weapons after World War II , represented a nation's standing in the world. Germany , France , Japan , Italy , Austria , and the United States all began dreadnought programmes; while the Ottoman Empire , Argentina , Russia , Brazil , and Chile commissioned dreadnoughts to be built in British and American yards. By virtue of geography,

22491-506: Was restricted to skirmishes. In the Baltic Sea , action was largely limited to the raiding of convoys, and the laying of defensive minefields; the only significant clash of battleship squadrons there was the Battle of Moon Sound at which one Russian pre-dreadnought was lost. The Adriatic was in a sense the mirror of the North Sea: the Austro-Hungarian dreadnought fleet remained bottled up by

22644-425: Was sunk by destroyers during the night phase of the Battle of Jutland. The German High Seas Fleet, for their part, were determined not to engage the British without the assistance of submarines; and since the submarines were needed more for raiding commercial traffic, the fleet stayed in port for much of the war. For many years, Germany simply had no battleships. The Armistice with Germany required that most of

22797-498: Was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy 's HMS  Dreadnought , had such an effect when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts . Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became

22950-417: Was to consider a new battleship. The specification for the new ship was a 12-inch main battery and anti-torpedo-boat guns but no intermediate calibres, and a speed of 21 kn (24 mph; 39 km/h), which was two or three knots faster than existing battleships. The initial designs intended twelve 12-inch guns, though difficulties in positioning these guns led the chief constructor at one stage to propose

23103-441: Was to persuade him of the need to standardise on 12-inch (305 mm) guns. Fisher's concerns were submarines and destroyers equipped with torpedoes, then threatening to outrange battleship guns, making speed imperative for capital ships . Fisher's preferred option was his brainchild, the battlecruiser : lightly armored but heavily armed with eight 12-inch guns and propelled to 25 knots (46 km/h) by steam turbines . It

23256-447: Was to prove this revolutionary technology that Dreadnought was designed in January 1905, laid down in October 1905 and sped to completion by 1906. She carried ten 12-inch guns, had an 11-inch armor belt, and was the first large ship powered by turbines. She mounted her guns in five turrets; three on the centerline (one forward, two aft) and two on the wings , giving her at her launch twice the broadside of any other warship. She retained

23409-485: Was usual. In October 1903, the Italian naval architect Vittorio Cuniberti published a paper in Jane's Fighting Ships entitled "An Ideal Battleship for the British Navy", which called for a 17,000-ton ship carrying a main armament of twelve 12-inch guns, protected by armour 12 inches thick, and having a speed of 24 knots (28 mph; 44 km/h). Cuniberti's idea—which he had already proposed to his own navy,
