HMS Audacious, a British super-dreadnought launched in 1912

A dreadnought was a battleship of the early 20th century, of a type modelled after the revolutionary HMS Dreadnought of 1906. Dreadnoughts were distinguished from previous battleships, known as pre-Dreadnoughts, by an 'all-big-gun' armament and by the use of steam turbines for propulsion.

Within a few years of HMS Dreadnought's launch, all navies were building ships inspired by her design. The product of British technical superiority and the willpower of Admiral Jackie Fisher, Dreadnought was no bolt from the blue. The concept of an all-big-gun ship had been in circulation for several years, and the Japanese had even laid down an all-big-gun battleship in 1904.^[1] The arrival of the Dreadnoughts sparked a new arms race, principally between Britain and Germany but reflected worldwide, as the new class of warships became a crucial symbol of national power. John Arbuthnot Fisher, 1st Baron Fisher John Arbuthnot Fisher, 1st Baron Fisher (January 25, 1841 – July 10, 1920), commonly known as Jackie Fisher, was a British admiral known for his efforts at naval reform. ... The term arms race in its original usage describes a competition between two or more parties for military supremacy. ...

Technical development continued rapidly through the dreadnought era, with step changes in armament, armor and propulsion meaning that ten years after Dreadnought's commissioning much more powerful ships were being built. These more powerful vessels were known as super-dreadnoughts.

The only pitched battle between fleets of dreadnoughts was the Battle of Jutland, an indecisive clash which reflected Britain's continuing strategic dominance. Most of the dreadnoughts were scrapped or scuttled after the end of World War I, though some of the most advanced super-dreadnoughts continued in service through World War II.

Early All-Big-Gun Projects and HMS Dreadnought

The Imperial Japanese Navy's Satsuma; the first ship designed as an 'all-big-gun' battleship

At the turn of the 20th century, the most powerful warship afloat was the type of battleship which has become known as the pre-dreadnought. These ships had been developed by gradual evolution from the ironclad of the 1870s and 1880s. They typically carried four heavy guns, typically of 12 in (305 mm) calibre, a secondary battery of guns between 6 and 9 in (15 and 23 cm), and a range of lighter weapons. They were powered by triple-expansion steam engines fed by high-pressure boilers, and protected by thick steel armour over their turrets, magazines and machinery spaces.

As fire control, guns and torpedoes improved, battles took place at increasingly long ranges, where only the heaviest guns were of use. At the Battle of Yalu River in September 1894, most damage was done at a range of about 2,000 m. By contrast, the Battle of the Yellow Sea in 1904 and the Battle of Tsushima in 1905 were conducted at ranges in excess of 7,000 m.

The result of the increase in engagement range was an increasingly heavy secondary battery; the Lord Nelson class carried ten 9.2-inch (234 mm) guns alongside their four 12-inch (305 mm) guns. A natural conclusion of this trend was the introduction of a battleship which had a uniform armament of the heaviest guns. A further inducement to an 'all-big-gun' design was that, with a mixed battery, it was difficult to have effective fire control. Fire was corrected by observing shell splashes in the water. It was impossible to tell shell-splashes caused by different batteries apart if the shells being fired were close to the same size. Also, different types of guns have different ballistics. Even guns of the same caliber can have different arcs of fire. A uniform type of armament solved this problem and greatly simplified fire control.^[2] The Lord Nelson class was a class of two battleships built by the Royal Navy between 1905 and 1908. ...

The all-big-gun concept was developed more or less simultaneously in four countries.

In 1900 the talented Admiral Jackie Fisher of the British Royal Navy, and a clique of designers and engineers around him, had drawn up design sketches for an all-big-gun ship. Fisher's rapid promotion into more senior positions gave him access to resources to develop his ideas, and when he achieved the rank of First Sea Lord in October 1904 he immediately set about gaining official approval for an all-big-gun ship. ... The Royal Navy of the United Kingdom is the oldest of the British armed services (and is therefore the Senior Service). ... The First Sea Lord is the professional head of the British Royal Navy. ...

Fisher was not premature; both the U.S. Navy and the Imperial Japanese Navy already had workable plans for all-big-gun ships. The Japanese design of 1903–4 featured eight 12-inch (305 mm) guns, a secondary battery of sixteen 6-inch (152 mm) guns, a planned displacement of 17000 tons, and a planned speed of 18 knots (33 km/h). The existence of the 6-inch secondary battery showed that the ships had not entirely parted company with the pre-dreadnought concept. The plan had to be abandoned because Japan was unable to acquire enough of the guns, which had to be imported from Britain. The ship was finished, as Satsuma, with four 12-inch (305 mm) and twelve 10-inch (254 mm) guns — history might well have known the all-big-gun battleship forever as the 'Satsuma'.^[3] Satsuma ) was a dreadnought type battleship of the Imperial Japanese Navy , designed and built in Japan by the Yokosuka Naval Yards. ...

The U.S. Navy began design studies for an all-big-gun ship in Autumn 1903. The idea had first reached President Roosevelt in 1901, and on 3 March 1905 Congress authorized the construction of two all-big-gun ships. These ships, like the Japanese design, had eight 12-inch (305 mm) guns; however they took the step of removing the secondary battery altogether, and there were no guns between their 12 inch (305 mm) main armament and the twenty-two 3-inch (76 mm) anti-torpedo-boat guns. This decision reflected the view that a battleship would only be called on to engage an armoured vessel at long range, and that plentiful rapid-firing armament was superior against torpedo boats.

Also in 1903, the famous shipbuilder Vittorio Cuniberti had published a paper in All the World's Fighting Ships entitled An Ideal Battleship for the British Navy. Cuniberti called for a 17,000 ton ship carrying a main armament of twelve 12-inch guns, protected by 12 inch (305 mm) armour and having a speed of 24 knots (44 km/h).^[5] Cuniberti had already proposed the idea to his own navy, the Italian Regia Marina, who had rejected it. Vittorio Cuniberti was an Italian military officer who envisioned the concept of the all big gun battleship, best exemplified by HMS Dreadnought. ...

The British Committee on Naval Designs started by Fisher met for the first time in January 1905. After considering a range of designs, particularly arrangements of the turrets, the Committee settled on a design carrying ten 12-inch (254 mm) guns as her main armament, along with twenty-seven 12-pounder (5 kg), i.e. 3 inch (76 mm), guns as her secondary armament. Not content with a revolutionary armament, the Royal Navy also introduced a steam turbine propulsion system, unprecedented in a large warship.^[6] The turbines promised a speed of 21 knots (39 km/h); the 2 to 3 knot (4 to 6 km/h) advantage over the typical pre-dreadnought and the other major ships was a significant tactical advantage.

Construction of the ship took place at a remarkable rate; her keel was laid on 2 October 1905, she was launched on 10 February 1906, and she was completed on 3 October 1906 — an impressive demonstration of British industrial might.^[7] The new ship was named Dreadnought, a suitably impressive name to set the tone for decades of naval history to come. The sixth HMS Dreadnought of the Royal Navy was a revolutionary battleship which entered service in 1906. ...

Dreadnought building

In 1897, before the revolution in design brought about by Dreadnought, the Royal Navy had 62 battleships in commission or building: a lead of 26 over France and of 50 over Germany.^[8] In 1906, the Royal Navy now had a lead of only one: Dreadnought herself. The new class prompted an arms race with serious strategic and economic consequences. Major naval powers raced to build their own dreadnoughts to catch up with the United Kingdom. Possession of modern battleships was not only vital to naval power, but as with nuclear weapons today, represented a nation's standing in the world.^[9] Germany, France, Russia, Italy, Austria and the United States all began dreadnought programmes; and second-rank powers including Turkey, Argentina, Brazil and Chile commissioned dreadnoughts to be built in British and American yards.^[10]

The Anglo-German arms race

See also: Causes of World War I For the war in general, see World War I. The Causes of World War I were complex and included many factors, including the conflicts and antagonisms of the four decades leading up to the war. ...

Britain and Germany had for some years been locked into a strategic struggle, as Germany asserted herself as a colonial as well as a European power. It was this threat which prompted the building of Dreadnought and made a naval arms race between the two nations inevitable.

While Fisher's reorganisation of the Navy in 1904 and 1905 actually cut the Naval Estimates,^[11] the pressing need for more and better ships to ensure naval superiority caused friction in the British government. The costs of maintaining the Royal Navy at a level capable of taking on the next two navies at the same time were immense.^[12]

The first German response to Dreadnought came with the Nassau-class, laid down in 1907, followed by the Helgoland-class in 1909. Together with two battlecruisers — a type for which the Germans had less admiration than Fisher, but which could be built under authorisation for armored cruisers, rather than capital ships — these classes gave Germany a total of ten modern capital ships built or building in 1909. While the British ships were somewhat faster and more powerful than their German equivalents, a 12:10 ratio fell very short of the 2:1 ratio that the Royal Navy wanted to maintain.^[9] The Nassau class were the first class of German Dreadnought battleships. ... The Helgoland class was a class of German Dreadnought battleships. ...

In 1909, the British Parliament authorised an additional four capital ships, holding out hope Germany would be willing to negotiate a treaty about battleship numbers. If no such solution could be found, an additional four ships would be laid down in 1910. Even this compromise solution meant (when taken together with some social reforms) raising taxes enough to prompt a constitutional crisis in Britain in 1909-10. The Peoples Budget was proposed by the Chancellor of the Exchequer David Lloyd George in 1909, and was a key issue of contention between the Liberal government and the House of Lords, ultimately leading to two general elections in 1910 and the enactment of the Parliament Act 1911. ...

In 1910, the British eight-ship construction plan went ahead, including four Orion-class super-dreadnoughts, and augmented by battlecruisers purchased by Australia and New Zealand. In the same period of time, Germany laid down only three ships, giving Britain a superiority of 22 ships to 13. The British resolve demonstrated by their construction programme led the Germans to seek a negotiated end to the arms race. While the Admiralty's new target of a 60% lead over Germany was near enough to Tirpitz's goal of cutting the British lead to 50%, talks foundered on the question on whether British Commonwealth battlecruisers should be included in the count, as well as non-naval matters like the German demands for recognition of her ownership of Alsace-Lorraine.^[9] // Orion was a hunter in Greek mythology. ... Imperial Province of Elsaß-Lothringen Alsace-Lorraine (German: , generally Elsass-Lothringen) was a territorial entity created by the German Empire in 1871 after the annexation of most of Alsace and parts of Lorraine in the Franco-Prussian War. ...

The pace of the dreadnought race stepped up in both nations' 1910 and 1911 budgets, with Germany laying down four capital ships each year and Britain five. The tensions came to a head following the German Naval Law of 1912. This proposed a fleet of 33 German battleships and battlecruisers, outnumbering the Royal Navy in home waters. To make matters worse, the Austro-Hungarian Fleet was building 4 dreadnoughts, while the Italians had four and were building two more. Against such threats, the Royal Navy could no longer guarantee vital British interests. Britain was faced with a choice of building more battleships, withdrawing from the Mediterranean, or seeking an alliance with France. Further naval construction was unacceptably expensive at a time when social welfare provision was making calls on the budget. Withdrawing from the Mediterranean would mean a huge loss of influence, weakening British diplomacy in the Mediterranean and shaking the stability of the British Empire. The only acceptable option, and the one taken by First Lord of the Admiralty Winston Churchill, was to overturn a hundred years of splendid isolation and seek an alliance with France.^[13] The Fleet Acts were four separate laws passed by the German Empire, in 1898, 1900, 1908, and 1912. ... ...

Splendid Isolation is the foreign policy pursued by Britain during the late 19th century, under the premierships of Benjamin Disraeli and The Marquess of Salisbury. ...

In spite of these important strategic consequences, the 1912 Naval Law had little bearing on the battleship force ratios. Britain responded by laying down ten new super-Dreadnoughts in her 1912 and 1913 budgets—ships of the Queen Elizabeth and Royal Sovereign classes which introduced a further step change in armament, speed and protection—while Germany laid down only five, focusing resources on the Army.^[9]

U.S. Navy dreadnoughts

The American South Carolina-class battleships were the first all-big-gun ships to be completed by one of Britain's rivals. The planning for the type had begun before the Dreadnought was launched, perhaps aided by secret briefing by sympathetic Royal Navy officials.^[9] Construction began in 1906, after the completion of the Dreadnought, and the type had no turbines. The United States Navys South Carolina class consisted of two battleships; USS South Carolina and USS Michigan, both of which were launched in 1908. ...

Smaller than Dreadnought at 16,000 tons standard displacement, they carried eight 12-inch (305 mm) guns in four twin turrets arranged in superfiring pairs fore and aft along the centerline of the keel. This arrangement gave South Carolina and her sister Michigan a broadside equal to Dreadnought's without requiring the cumbersome wing turrets of the first few British dreadnought classes. The superfiring or superimposed arrangement had not been proven until after South Carolina went to sea, and it was initially feared the weakness of the previous Virginia-class would recur. Half of the first ten U.S. dreadnoughts used the older and less efficient reciprocating engines rather than turbines, which made many U.S. battleships slower than their British counterparts, but gave them much greater range, something of great importance in the Pacific. In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place, so that it can be weighed. ...

Japan

The Japanese battleship Settsu

With the defeat of the Russians, the Japanese navy became concerned about the potential for conflict with the USA. Japanese theorist Sato Tetsutaro developed the concept of a fleet at a minimum 70% of the U.S.'s to win a "decisive battle" (per the doctrine of Mahan^[14]). However, Japan's first priority was to refit the pre-dreadnoughts she had captured from Russia, and to complete the Satsuma and Aki. Like the USN's South Carolinas, the Satsumas were designed before Dreadnought. Indeed, Satsuma was the first in the world to be planned and laid down as an all-big-gun battleship; unfortunately gun shortages delayed her completion and resulted in her carrying a mixed armament, so she was known as a semi-Dreadnought.

Compared to the other major naval powers, France was slow to start building dreadnoughts, instead finishing the planned Danton-class of pre-dreadnoughts, laying down five in 1907 and 1908. It was not until September 1910 the first of the Courbet-class was laid down, making France the eleventh nation to enter the dreadnought race. The dreadnought race saw France drop from second to fifth in terms of naval power; however, the closer alliance with Britain made these reduced forces more than adequate for French needs.^[9] Image File history File links Size of this preview: 800 × 536 pixelsFull resolution (864 × 579 pixel, file size: 104 KB, MIME type: image/jpeg) le Provence, livret ONI203 pour lidentification des navires de la marine française, édité par la Division du Renseignement Naval du Départment de la...

Even though Cuniberti had promoted the idea of an all-big-gun battleship in Italy well before Dreadnought, it took until 1909 for Italy to lay down one of her own. The construction of Dante Alighieri was prompted by rumours of Austro-Hungarian dreadnought building. A further five Dreadnoughts of the Cavour- and Andrea Doria-class followed as Italy sought to maintain its lead over Austria-Hungary.

In January 1909, Austro-Hungarian admirals circulated a document calling for a fleet of four dreadnoughts. However, a constitutional crisis in 1909-10 meant no construction could be approved. In spite of this, two dreadnoughts were laid down by shipyards on a speculative basis, and later approved along with an additional two.

Brazil managed the remarkable achievement of being the third country with a dreadnought under construction, laying down two in British shipyards in 1907. This sparked off a small-scale arms race in South America, as Argentina and then Chile commissioned dreadnoughts. Argentina placed orders in American yards and Chile in Britain, meaning that both of Chile's two battleships were purchased by the British on the outbreak of war. One of them was later returned to the Chilean government.

Turkey ordered two dreadnoughts from British yards which were seized by the British while Greece's, ordered from Germany, was taken over by the Germans. The main armament, ordered in the United States, consequently equipped a class of British monitors. Greece in 1914 purchased two pre-dreadnoughts from the United States Navy, renaming them Kilkis and Limnos in Royal Hellenic Navy service.

The arrival of super–Dreadnoughts is not as clearly identified with a single ship in the same way that the Dreadnought era was initiated by HMS Dreadnought. However, it is commonly held to start with the British Orion-class, and for the German navy with the König. What made them "super" was the unprecedented jump in displacement of 2,000–tons over the previous class, the introduction of the heavier 13.5inch (343 mm) gun, and the distribution of all the main armament on the centreline. Thus, in the four years between the laying down of Dreadnought and Orion, displacement had increased by 25%, and weight of broadside had doubled.

In Japan, two Fuso-class super-dreadnoughts were laid down in 1912, followed by the Ises in 1914, with both classes carrying twelve 14-inch (356 mm) guns. In 1917, the Nagato-class was ordered, the first dreadnoughts to mount 16-inch guns, possibly making them the most powerful warships in the world. All were increasingly built from Japanese rather than imported components. In France, the Courbets were followed by three super-dreadnoughts of the Bretagne-class; another five Normandies were cancelled on the outbreak of World War One. The Fuso class (Japanese: 扶桑, an old name for Japan), was a type battleship of the Imperial Japanese Navy, designed before the First World War. ... Image:Battleship Ise. ...

The later super-dreadnoughts, principally the Queen Elizabeth-class, dispensed with the "Q" turret amidships, so weight and volume were freed up for larger, oil-fired boilers. Oil had many advantages as a fuel over coal. It had more energy density than coal, and its liquid form vastly simplified refuelling arrangements; oil required no stokers, and emitted much less smoke, aiding gun laying and making the ships less visible on the horizon. The new 15 inch gun (381 mm) gave greater firepower in spite of the loss of a turret, and there was a thicker armour belt and improved underwater protection. The class had a 25 knot (46 km/h) design speed and they were considered the first fast battleships. The Queen Elizabeth class battleships were five super-dreadnoughts of the Royal Navy, named in honour of Elizabeth I of England. ... Energy density is the amount of energy stored in a given system or region of space per unit volume or per unit mass, depending on the context. ... Gun laying is the process of aiming an artillery piece. ... The BL 15 inch Mark I was the first British 15 inch (381 mm) gun design and the most widely used and longest lasting of any British designs. ... Historically, a fast battleship was a battleship of which the design featured an emphasis on speed which was unusual, compared to the normal practice of the time. ...

The design weakness of super-dreadnoughts, which distinguished them from post-World War I designs, was armor disposition. Their design placed emphasis on vertical protection, needed in short range battles. These ships were capable of engaging the enemy at 20,000 metres, but were vulnerable to the high angle ("plunging") fire at such ranges. Post-war designs typically had 5 to 6 inches (130 to 150 mm) of deck armor to defend against this. The concept of zone of immunity became a major part of the thinking behind battleship design. Lack of underwater protection was also a weakness of these pre-World War I designs which were developed only as the threat of the torpedo became real.

The United States Navy's "standard"-type battleships, beginning with the Nevada-class, or "Battleship 1912", were designed with long-range engagements and plunging fire in mind; the first of these was laid down in 1912, five years before the Battle of Jutland taught the dangers of long-range fire to European navies. Important features of the standard battleships were "all or nothing" armor and "raft" construction, a philosophy under which only the parts of the ship worth giving the thickest possible protection were worth armoring at all, and enough reserve buoyancy should be contained within the resulting armored "raft" to keep afloat the entire ship in the event the unarmored bow and stern were thoroughly riddled and flooded. The Nevada class battleships carried the United States Navys first triple gun turrets, a feature that would be seen in all but a few of its future battleship designs. ...

British Grand Fleet during World War I

The First World War was almost an anticlimax for the great Dreadnought fleets. There was no decisive clash of modern battlefleets to compare with the Battle of Tsushima. The role of battleships was marginal to the great land struggle in France and Russia; and it was equally marginal to the First Battle of the Atlantic, the battle between German submarines and British merchant shipping.

By virtue of geography, the Royal Navy could keep the German High Seas Fleet bottled up in the North Sea with relative ease. Both sides were aware that, because of the greater number of British Dreadnoughts, a full fleet engagement would result in a British victory. The German strategy was therefore to try to provoke an engagement on favourable terms: either inducing a part of the Grand Fleet to enter battle alone, or to fight a pitched battle near the German coastline, where friendly fields, torpedo-boats and submarines could be used to even the odds.^[19] German battlecruiser Derfflinger scuttled at Scapa Flow. ...

The first two years of war saw conflict in the North Sea limited to skirmishes by battlecruisers at the Battle of Heligoland Bight and Battle of Dogger Bank and raids on the English coast. In the summer of 1916, a further attempt to draw British ships into battle on favourable terms resulted in a clash of the battlefleets in the Battle of Jutland: an indecisive engagement.^[20] HMS Hood (left) and the battleship HMS Barham (right), in Malta, 1937. ...

In the other naval theatres there were no decisive pitched battles. In the Black Sea, Russian and Turkish battleships skirmished, but nothing more. In the Baltic, action was largely limited to convoy raiding and the laying of defensive minefields; the only significant clash of battleship squadrons 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 British and French blockading fleets. And in the Mediterranean, the most important use of battleships was in support of the amphibious assault on Gallipoli. The Battle of Moon Sound was a naval battle in World War I, fought in the Autumn of 1917 between German and Russian forces in the Baltic sea. ...

The course of the war also illustrated the vulnerability of battleships to cheaper weapons. In September 1914, the U-boat threat to capital ships was demonstrated by successful attacks on British cruisers, including the sinking of three British armored cruisers by the German submarine U-9 in less than an hour. Sea mines proved a threat the next month, when the recently commissioned British super-Dreadnought Audacious struck a mine. By the end of October, British strategy and tactics in the North Sea had changed to reduce the risk of U-boat attack.^[21] While Jutland was the only major clash of battleship fleets in history, the German plan for the battle relied on U-boat attacks on the British fleet; and the escape of the German fleet from the superior British firepower was effected by the German cruisers and destroyers closing on British battleships, causing them to turn away to avoid the threat of torpedo attack. Further near-misses from submarine attacks on battleships and casualties amongst cruisers led to growing paranoia in the Royal Navy about the vulnerability of battleships. By October 1916, the Royal Navy had essentially abandoned the North Sea, instructing the Grand Fleet not to go south of the Farne Islands unless adequately protected by destroyers. The capital ships of a navy are its important warships; the ones with the heaviest firepower and armor. ... Unterseeboot 9 (also known as U-9) was a German U-boat built for the Kaiserliche Marine. ... HMS Audacious was a King George V class battleship of the Royal Navy. ... The Inner Farne seen from Seahouses harbour The Farne Islands (also referred to less formally as the Farnes) are a group of islands off the coast of Northumberland, England. ...

For the German part, the High Seas Fleet determined not to engage the British without the assistance of submarines; and since the submarines were more needed for commerce raiding, the fleet stayed in port for the remainder of the war.^[22] Other theatres equally showed the role of small craft in damaging or destroying Dreadnoughts. The two Austrian Dreadnoughts lost in 1918 were the casualties of torpedo boats and of frogmen.

After World War I

Most of the dreadnoughts were scrapped in the years after World War I. The German dreadnought fleet was scuttled at Scapa Flow by its crew. Britain, the USA and Japan briefly made plans for another bout of naval expansion, but concluded the Washington Naval Treaty to prevent another costly arms race. Most of the British fleet was scrapped as a result of the terms of the Washington Treaty and the expenditure cuts known as the Geddes Axe. The most modern super-Dreadnoughts of all three navies, together with some battlecruisers, formed the bulk of international naval strength through the 1920s and 1930s and, with some modernisation, into World War II It has been suggested that Gutter Sound be merged into this article or section. ... The Washington Naval Treaty limited the naval armaments of its five signatories: the United States, the British Empire, the Empire of Japan, the French Third Republic, and Italy. ...

The term "dreadnought" gradually dropped from use. After World War I the pre-dreadnoughts and the first generations of dreadnoughts were scrapped; all battleships shared the characteristics of the dreadnought.
