In naval terminology, a destroyer is a fast and maneuverable yet long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against smaller, powerful, short-range attackers. The first ship named and classified as a destroyer was the Spanish warship Destructor (1886), designed by Fernando Villaamil and constructed in England in the shipyard of James and George Thomson of Clydebank, near the Yarrow shipyards. By the time of the Russo-Japanese War in 1904, TBDs were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats." Although the term destroyer had been used interchangeably with the terms "TBD" and "torpedo boat destroyer" by navies since 1892, the term torpedo boat destroyer had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
Prior to World War II, destroyers were light vessels with little endurance for unattended ocean operations; typically a number of destroyers and a single destroyer tender operated together. After the war, the advent of the guided missile allowed destroyers to take on the surface combatant roles previously filled by battleships and cruisers. This resulted in larger and more powerful destroyers more capable of independent operation.
At the beginning of the 21st century, destroyers are the heaviest surface combatant ships in general use, with only three nations (the United States, Russia, and Peru) operating the heavier class cruisers and none operating battleships or true battlecruisers. Modern destroyers, also known as guided missile destroyers, are equivalent in tonnage but vastly superior in firepower to cruisers of the World War II era, capable of carrying nuclear missiles. Guided missile destroyers such as the Arleigh Burke-class class are actually larger and more heavily armed than most previous ships classified as guided missile cruisers, due to their massive size at 510 feet (160 m) long, displacement (9200 tons) and armament of over 90 missiles.
Early history, torpedo boat destroyersEdit
The emergence and development of the destroyer, up until World War II, was related to the invention of the self-propelled torpedo in the 1860s. A navy now had the potential to destroy a superior enemy battle fleet using steam launches to launch torpedoes. Fast boats armed with torpedoes were built and called torpedo boats. By the 1880s, these had evolved into small ships of 50–100 tons, fast enough to evade enemy picket boats.
At first, the danger to a battle fleet was considered only to exist when at anchor, but as faster and longer-range torpedoes were developed, the threat extended to cruising at sea. In response to this new threat, more heavily gunned picket boats called "catchers" were built which were used to escort the battle fleet at sea. They needed the same seaworthiness and endurance, and as they necessarily became larger, they became officially designated "torpedo boat destroyers", and by the First World War were largely known as "destroyers" in English. The anti-torpedo boat origin of this type of ship is retained in its name in other languages, including French (contre-torpilleur), Italian (cacciatorpediniere), Portuguese (contratorpedeiro), Polish (kontrtorpedowiec), Czech (torpédoborec), Greek (antitorpiliko,αντιτορπιλικό), and Dutch (torpedobootjager).
Once destroyers became more than just catchers guarding an anchorage, it was realized that they were also ideal to take over the role of torpedo boats themselves, so they were fitted with torpedo tubes as well as guns. At that time, and even into World War I, the only function of destroyers was to protect their own battle fleet from enemy torpedo attacks and to make such attacks on the battleships of the enemy. The task of escorting merchant convoys was still in the future.
An important development came in 1884 with HMS Swift, a large torpedo boat with six 47 mm quick-firing guns and three torpedo tubes. While still not fast enough to engage torpedo boats reliably, she at least had the armament to deal with them.
The Japanese torpedo boat Kotaka (Falcon) of 1885 was "the forerunner of torpedo boat destroyers that appeared a decade later". Designed to Japanese specifications and ordered from the London Yarrow shipyards in 1885, she was transported in parts to Japan, where she was assembled and launched in 1887. The 165-foot (50 m) long vessel was armed with four 1-pounder (37 mm) quick-firing guns and six torpedo tubes, reached 19 knots (35 km/h), and at 203 tons, was the largest torpedo boat built to date. In her trials in 1889, Kotaka demonstrated that she could exceed the role of coastal defense, and was capable of accompanying larger warships on the high seas. The Yarrow shipyards, builder of the parts for the Kotaka, "considered Japan to have effectively invented the destroyer".
Almost immediately after the order of Kotaka was placed, Fernando Villaamil, second officer of the Ministry of the Navy of Spain, was put in charge of developing the concept of a new ship designed to combat boats. He placed an order for a large gunboat in November 1885, with the British builder James and George Thompson, of Clydebank. The ship, named Destructor (literally Destroyer), was laid down at the end of the year, launched in 1886, and commissioned in 1887. Her displacement was 380 tons, and she was armed with one 90 mm Hontoria gun, four 57 mm Nordenfelt guns, two 37 mm Hotchkiss cannons and three Schwarzkopf tubes. Her complement was 60 men. In terms of gunnery, speed (22.5 knots in trials) and dimensions, the specific design to chase boats and her high seas capabilities, Destructor is widely considered the first boat destroyer ever built. The Destructor is thought to have influenced the concept and designation of destroyers developed by the British Navy shortly after.
The Royal Navy began experiments with the "boat catcher", a class of 17 large boats. In tests, HMS Rattlesnake proved to be marginally faster than boats, but not fast enough to be decisive.
The first ships to bear the formal designation "boat destroyer" (TBD) were the Daring class of two ships and Havock class of two ships of the Royal Navy, developed in 1892 under the newly appointed Third Sea Lord Rear Admiral "Jackie" Fisher. The Daring and Decoy were ordered on 27 June 1892 from John I. Thornycroft & Company at Chiswick, while the Havock and Hornet were ordered five days later from Yarrow at Poplar. The Daring and Decoy were completed in 1895 and the Havock and Hornet were completed in 1894. Each was armed with a single 12-pounder (76 mm) gun, three 6-pounders (57 mm), and three 46 cm tubes. They also had the range and speed to travel effectively with a battle fleet.
The French navy, an extensive user of boats, built its first boat destroyer in 1899, with the Durandal-class 'torpilleur d'escadre'.
Early boat-destroyer designsEdit
Boat-destroyer designs continued to evolve around the turn of the 20th century in several key ways. The first was the introduction of the steam turbine. The spectacular unauthorized demonstration of the turbine powered Turbinia at the 1897 Spithead Navy Review, which, significantly, was of boat size, prompted the Royal Navy to order a prototype turbine powered destroyer, HMS Viper of 1899. This was the first turbine warship of any kind and achieved a remarkable 36 knots (67 km/h) on sea trials. By 1910 the turbine had been widely adopted by all navies for their faster ships.
The second development was the replacement of the boat-style turtleback foredeck by a raised forecastle for the new River-class destroyers built in 1903, which provided better sea-keeping as well as more space below deck.
The British experimented with oil propulsion for the Tribal class of 1905 but switched temporarily back to coal for the later Beagle class in 1909. Other navies also adopted oil, for instance the USN with the Paulding class of 1909. In spite of all this variety, destroyers adopted a largely similar pattern. The hull was long and narrow, with a relatively shallow draft. The bow was either raised in a forecastle or covered under a turtleback; underneath this were the crew spaces, extending 1/4 to 1/3 the way along the hull. Aft of the crew spaces was as much engine space as the technology of the time would allow: several boilers and engines or turbines. Above deck, one or more quick-firing guns were mounted in the bows, in front of the bridge; several more were mounted amidships and astern. Two tube mountings (later on, multiple mountings) were generally found amidships.
Between 1892 and 1914 destroyers became markedly larger: initially 420 tons with a length of 250 feet (76 m) for the US Navy's first Bainbridge class of boat destroyers, up to the First World War with 300-foot (91 m) long destroyers displacing 1000 tons was not unusual. However, construction remained focused on putting the biggest possible engines into a small hull, resulting in a somewhat flimsy construction. Often hulls were built of steel only 1/8 in thick.
By 1910 the steam-driven displacement (that is, not hydroplaning) boat had become redundant as a separate type. Germany nevertheless continued to build such boats until the end of World War I, although these were effectively small coastal destroyers. In fact Germany never distinguished between the two types, giving them pennant numbers in the same series and never giving names to destroyers. Ultimately the term boat came to be attached to a quite different vessel – the very fast hydroplaning motor driven MTB.
Life on board destroyersEdit
Early destroyers were extremely cramped places to live, being "without a doubt magnificent fighting vessels... but unable to stand bad weather." During the Russo-Japanese War in 1904, the commander of the boat destroyer Akatsuki described "being in command of a destroyer for a long period, especially in wartime... is not very good for the health." Stating that he had originally been strong and healthy, he continued, "life on a destroyer in winter, with bad food, no comforts, would sap the powers of the strongest men in the long run. A destroyer is always more uncomfortable than the others, and rain, snow, and sea-water combine to make them damp; in fact, in bad weather there is not a dry spot where one can rest for a moment."
The Japanese destroyer commander finished with, "Yesterday I looked at myself in a mirror for a long time; I was disagreeably surprised to see my face thin, full of wrinkles, and as old as though I were fifty. My clothes (uniform) cover nothing but a skeleton, and my bones are full of rheumatism."
Although officially classified as a boat in 1898 by the US Navy, the USS Porter, a 175-foot (53 m) long all steel vessel displacing 165 tons, was described by her commander, LT. John C. Fremont, as "...a compact mass of machinery not meant to keep the sea nor to live in... as five sevenths of the ship are taken up by machinery and fuel, whilst the remaining two sevenths, fore and aft, are the crew's quarters; officers forward and the men placed aft. And even in those spaces are placed anchor engines, steering engines, steam pipes, etc. rendering them unbearably hot in tropical regions."
Early boat-destroyer tactics and engagementsEdit
The boat destroyer's initial purpose was to protect against boats, but navies soon appreciated the flexibility of the fast, multi-purpose vessel that resulted. Vice-Admiral Sir Baldwin Walker laid down destroyer duties for the Royal Navy:
- Screening the advance of a fleet when hostile craft are about
- Searching a hostile coast along which a fleet might pass
- Watching an enemy's port for the purpose of harassing his craft and preventing their return
- Attacking an enemy fleet
The boat destroyer's first major use in combat came during the Japanese surprise attack on the Russian fleet anchored in Port Arthur at the opening of the Russo-Japanese War on 8 February 1904. Three destroyer divisions attacked the Russian fleet in port, firing a total of 18 torpedoes. However only two Russian battleships were seriously damaged due to the proper deployment of torpedo nets. The Russian flagship, the battleship Tsesarevich, which had her nets deployed, had at least four enemy torpedoes "hung up" in them, other warships were similarly saved from further damage by the Russian navy's proper use of torpedo nets.
World War IEdit
While capital ship engagements were scarce in World War I, destroyer units were almost continually engaged in raiding and patrol actions. The first shot of the war at sea was fired on 5 August 1914 by a destroyer of the 2nd Flotilla, HMS Lance, in an engagement with the German auxiliary minelayer SS Königin Luise.
Destroyers were involved in the skirmishes that prompted the Battle of Heligoland Bight, and filled a range of roles in the Battle of Gallipoli, acting as troop’s transports and fire support vessels, as well as their fleet-screening role. Over 80 British destroyers and 60 German torpedo-boats took part in the Battle of Jutland, which involved pitched small-boat actions between the main fleets, and several foolhardy attacks by unsupported destroyers on capital ships. Jutland also concluded with a messy night action between the German High Seas Fleet and part of the British destroyer screen.
The threat evolved by World War I with the development of the submarine, or U-boat. The submarine had the potential to hide from gunfire and close underwater to fire torpedoes. Early-war destroyers had the speed and armament to intercept submarines before they submerged, either by gunfire or by ramming. Destroyers also had a shallow enough draft that torpedoes would find it difficult to hit them.
The desire to attack submarines underwater led to rapid destroyer evolution during the war; they were quickly equipped with strengthened bows for ramming, depth charges and hydrophones for identifying submarine targets. The first submarine casualty to a destroyer was the German U-19, rammed by HMS Badger on 29 October 1914. While U-19 was only damaged, the next month Garry successfully sank U-18. The first depth-charge sinking was on 4 December 1916, when UC-19 was sunk by HMS Llewellyn.
The submarine threat meant that many destroyers spent their time on anti-submarine patrol; once Germany adopted unrestricted submarine warfare in January 1917, destroyers were called on to escort merchant convoys. US Navy destroyers were among the first American units to be dispatched upon the American entry to the war, and a squadron of Japanese destroyers even joined Allied patrols in the Mediterranean. Patrol duty was far from safe; of the 67 British destroyers lost in the war, collisions accounted for 18, while 12 were wrecked.
At the end of the war the state-of-the-art was represented by the British W-class.
The trend during World War I had been towards larger destroyers with heavier armaments. A number of opportunities to fire at capital ships had been missed during the War, because destroyers had expended all their torpedoes in an initial salvo. The British 'V' & 'W' classes of the late war had sought to address this by mounting six torpedo tubes in two triple mounts, instead of the four or two on earlier models. The 'V' and 'W's set the standard of destroyer building well into the 1920s.The next major innovation came with the Japanese Fubuki class or 'special type', designed in 1923 and delivered in 1928. The design was initially noted for its powerful armament of six five-inch (127 mm) guns and three triple torpedo mounts. The second batch of the class gave the guns high-angle turrets for anti-aircraft warfare, and the 24-inch (61 cm) oxygen-fueled 'Long Lance' Type 93 torpedo. The later Hatsuharu class of 1931 further improved the torpedo armament by storing its reload torpedoes close at hand in the superstructure, allowing reloading within 15 minutes.
Most other nations replied with similar larger ships. The US Porter class adopted twin five-inch (127 mm) guns, and the subsequent Mahan class and Gridley class (the latter of 1934) increased the number of torpedo tubes to 12 and 16 respectively.
In the Mediterranean, the Italian Navy's building of very fast light cruisers of the Condottieri class prompted the French to produce exceptional destroyer designs. The French had long been keen on large destroyers, with their Chacal class of 1922 displacing over 2,000 tons and carrying 130 mm guns; a further three similar classes were produced around 1930. The Fantasque class of 1935 carried five 138 millimetres (5.4 in) guns and nine torpedo tubes, but could achieve speeds of 45 knots (83 km/h), which remains the record speed for a steamship and for any destroyer. The Italians' own destroyers were almost as swift, most Italian designs of the 1930s being rated at over 38 knots (70 km/h), while carrying torpedoes and either four or six 120 mm guns.
Germany started to build destroyers again during the 1930s as part of Hitler's rearmament program. The Germans were also fond of large destroyers, but while the initial Type 1934 displaced over 3,000 tons, their armament was equal to smaller vessels. This changed from the Type 1936 onwards, which mounted heavy 150 millimetres (5.9 in) guns. German destroyers also used innovative high-pressure steam machinery: while this should have helped their efficiency, it more often resulted in mechanical problems.
Once German and Japanese rearmament became clear, the British and American navies consciously focused on building destroyers that were smaller but more numerous than those used by other nations. The British built a series of destroyers (the A class to I class) which were about 1,400 tons standard displacement, had four 4.7-inch (119 mm) guns and eight torpedo tubes; the American Benson class of 1938 similar in size, but carried five 5-inch (127 mm) guns and ten torpedo tubes. Realizing the need for heavier gun armament, the British built the Tribal class of 1936 (sometimes called Afridi after one of two lead ships). These ships displaced 1,850 tons and were armed with eight 4.7-inch (119 mm) guns in four twin turrets and four torpedo tubes. These were followed by the J-class and L-class destroyers, with six 4.7-inch (119 mm) guns in twin turrets and eight torpedo tubes.
Anti-submarine sensors included sonar (or ASDIC), although training in their use was indifferent. Anti-submarine weapons changed little, and ahead-throwing weapons, a need recognized in World War I, had made no progress.
Operations in the inter-war periodEdit
During the 1920s and 1930s destroyers were often deployed to areas of diplomatic tension or humanitarian disaster. British and American destroyers were common on the Chinese coast and rivers, even supplying landing parties to protect colonial interests.
World War IIEdit
By World War II the threat had evolved once again. Submarines were more effective, and aircraft had become important weapons of naval warfare; once again the fleet destroyers were ill-equipped for combating these new targets. They were fitted with new anti-aircraft guns, radar, and forward-launched ASW weapons, in addition to their existing light guns, depth charges, and torpedoes. By this time the destroyers had become large, multi-purpose vessels, expensive targets in their own right. As a result, casualties on destroyers were one of the highest. This led to the introduction of smaller and cheaper specialized anti-submarine warships called corvettes and frigates by the Royal Navy and destroyer escorts by the USN. A similar programme was belatedly started by the Japanese (see Matsu-class destroyer). These ships had the size and displacement of the original torpedo boat destroyers that the contemporary destroyer had evolved from.
Some conventional destroyers were completed in the late 1940s and 1950s which built on wartime experience. These vessels were significantly larger than wartime ships and had fully automatic main guns, unit Machinery, radar, sonar, and antisubmarine weapons such as the Squid mortar. Examples include the British Daring class, US Forrest Sherman class, and the Soviet Kotlin-class destroyers.
Some World War II–vintage ships were modernized for anti-submarine warfare, and to extend their service lives, to avoid having to build (expensive) brand-new ships. Examples include the US FRAM I programme and the British Type 15 frigates converted from fleet destroyers.
The advent of surface-to-air missiles and surface-to-surface missiles, such as the Exocet, in the early 1960s changed naval warfare. Guided missile destroyers (DDG in the US Navy) were developed to carry these weapons and protect the fleet from air, submarine and surface threats. Examples include the Soviet Kashin class, the British County class, and the American Charles F. Adams class.
In the US Navy, fleet destroyers operate in support of carrier battle groups, surface action groups, amphibious groups and replenishment groups. The destroyers currently in use by the US Navy are the Arleigh Burke class. Destroyers (with a DD hull classification symbol) primarily perform anti-submarine warfare duty while guided missile destroyers (DDGs) are multi-mission (anti-submarine, anti-aircraft and anti-surface warfare) surface combatants, with an emphasis on anti-surface warfare.
The addition of cruise missile launchers has greatly expanded the role of the destroyer in strike and land-attack warfare. As the expense of heavier surface combatants has generally removed them from the fleet, destroyer tonnage has grown (a modern Arleigh Burke-class destroyer has the same tonnage as a World War II light cruiser).
In October 2013 the first of three U.S. Zumwalt-class class of destroyers left dry dock, the destroyer built with specific structural angles and a superstructure wrapped in a carbon fiber composite canopy to reduce its radar detectability by a factor of 50. The ship, with 80 missiles and a crew of 150, will include two Advanced Gun Systems (AGS) that can fire rocket powered, computer-guided shells to destroy targets 63 miles away.
The Royal Navy operates the Type 45, or Daring class, stealth destroyer which displaces roughly 7,200 tonnes. A class of six ships is envisaged. They are equipped with the UK variant of the Principal Anti-Air Missile System (PAAMS) and BAE Systems SAMPSON radar.
The Italian Navy and the French Navy each operate two Horizon-class destroyers and will soon operate new FREMM destroyers. These stealth ships are armed with anti-ship missiles and Aster surface-to-air missiles. The Italian navy also operates two Durand de la Penne-class destroyers. The French navy also operates seven Georges Leygues-class destroyers, two Cassard-class destroyers and one Tourville-class destroyer. The French Navy and the Italian navy apply the term "first-class frigate" to their destroyers in service (under NATO classification).
The Royal Canadian Navy operates the Iroquois-class destroyers, a class of four helicopter-carrying, anti-aircraft, guided missile destroyers (with three remaining in service). They were originally fitted out for anti-submarine warfare, but the entire class underwent major retrofits in the 1990s which re-purposed the ships as area air-defence destroyers.
The Indian Navy operates three Delhi-class destroyers. These ships are armed with Kh-35 missiles, which have a range of 130 km, in the anti-ship role. They will be replaced by the Brahmos cruise missiles. Shtil (SA-N-7 Gadfly) system is installed to counter airborne threats. The Barak 1 point-defense missile system has been installed in INS Delhi and will soon be installed in the other two ships of its class. These destroyers also carry anti-submarine rockets and torpedoes. The destroyers have the capability to carry two Sea King helicopters. The Delhi class will be augmented by the new Kolkata-class destroyers, the first of which was launched in March 2006.
Since 2003, the Chinese People's Liberation Army Navy has launched the Luyang I, Luyang II and Luzhou classes. The latter two are armed with long range air defense missiles, the indigenous HQ-9 and the Russian S-300 respectively.
The Republic of Korea Navy operates several classes of destroyers including the Sejong the Great class (KDX-III), the Chungmugong Yi Sun-shin class (KDX-II) and Gwanggaeto the Great class (KDX-I) of destroyers. The KDX-III is equipped with the Aegis combat system, Goalkeeper CIWS, Hyunmoo cruise missile and the Hae Sung anti-ship missile.
The Russian Navy and the People's Liberation Army Navy of the People's Republic of China operate the Sovremenny class, a class of large multi-purpose missile destroyers. They are powered by pressure-fired boilers, making them capable of speeds in excess of 30 knots (56 km/h). Their armament consists of eight SS-N-22 Sunburn anti-ship missiles, launchers for SA-N-7 Gadfly anti-air missiles and two AK-130 twin-barreled 130 mm automatic naval guns which can fire laser-guided shells. While they also carry 533 mm torpedo tubes and RBU-6000 rocket launchers for use against submarines, their primary mission is to attack surface ships. Their anti-aircraft missiles have a surface attack mode, and both the 130 mm guns and the torpedoes are useful against ships at close range.
The modern Udaloy-class destroyer destroyers of the Russian Navy can displace about 7,900 tonnes, can travel at 35 knots (65 km/h), and have a maximum range of 10,500 nm (19,450 km) at 14 knots (26 km/h). The original class (Udaloy I) was designed for anti-submarine warfare, which can be seen in their two quadruple launchers of the Metel Anti-Ship Complex (SS-N-14), two quadruple 533 millimetres (21 in) launchers equipped with either the Type 53 torpedo on the Udaloy I class or RPK-2 Viyuga (SS-N-15) on the Udaloy II class, and the two RBU-6000 anti-submarine launchers. The II class is Russia's only multipurpose destroyer. The armament of the class has been modified. The Metal Anti-Ship Complex is replaced with eight P-270 Moskit (SS-N-22 Sunburn) supersonic sea-skimming anti-ship missile. For air defense, each Udaloy is armed with four AK-630 CIWSs, mounted parallel to each other mid ship. They also have two Kashtan CIWSs, each capable of engaging six targets automatically by either its armament of two GSh-6-30 Gatling guns or four 9M311 (SA-N-11) surface-to-air missiles. Finally, 64 3K95 Kinzhal (SA-N-9) medium-range point defense SAMs can be fired from vertical launching system.
The last US Navy Spruance-class destroyer in service, USS Cushing, was decommissioned on September 21, 2005. The Zumwalt class is planned to replace them; on November 1, 2001, the US Navy announced the issuance of a revised Request for Proposal (RFP) for the Future Surface Combatant Program. Formerly known as DD 21, the program was renamed DD(X) (and later renamed to DDG-1000) to more accurately reflect the program purpose, which is to produce a family of advanced technology surface combatants, not a single ship class. DD(X), also called Zumwalt class, is much larger than traditional destroyers, nearly three thousand tons heavier than a Ticonderoga-class cruiser (15,610 long tons, larger than most heavy cruisers from the World War II era). It will potentially employ advanced weaponry and an all-electric Integrated Power System; however, the construction program was subsequently reduced to just two vessels, and there is currently only funding for three in total. With the retirement of the Spruance class, the US Navy began commissioning an advanced variant of the Arleigh Burke class with expanded ASW capabilities, the Arleigh Burke Flight IIA, beginning with USS Oscar Austin. As of 2015[update], 34 of these vessels are in service, with more under construction.
