114-616: The Air Defense Artillery Branch is the air defense branch of the United States Army , specializing in the use of anti-aircraft weapons (such as surface-to-air missiles ) to conduct anti-aircraft warfare operations. In the U.S. Army, these groups are composed of mainly air defense systems such as the Patriot Missile System , Terminal High Altitude Area Defense (THAAD) , and the Avenger Air Defense system which fires
228-545: A limited and asymmetric nature. Naval warfare developed when humans first fought from water-borne vessels. Before the introduction of the cannon and ships with enough capacity to carry them, navy warfare primarily involved ramming and boarding actions. In the time of ancient Greece and the Roman Empire , naval warfare centered on long, narrow vessels powered by banks of oarsmen (such as triremes and quinqueremes ) designed to ram and sink enemy vessels or come alongside
342-489: A sister ship of Bismarck , was almost put out of action by miniature submarines known as X-Craft . The X-Craft severely damaged her and kept her in port for some months. A major paradigm shift in naval warfare occurred with the introduction of the aircraft carrier . First at Taranto in 1940 and then at Pearl Harbor in 1941, the carrier demonstrated its ability to strike decisively at enemy ships out of sight and range of surface vessels. The Battle of Leyte Gulf (1944)
456-600: A 75 mm 12-pounder, and even a 105 mm gun. Erhardt also had a 12-pounder, while Vickers Maxim offered a 3-pounder and Schneider a 47 mm. The French balloon gun appeared in 1910, it was an 11-pounder but mounted on a vehicle, with a total uncrewed weight of two tons. However, since balloons were slow moving, sights were simple. But the challenges of faster moving aeroplanes were recognised. By 1913 only France and Germany had developed field guns suitable for engaging balloons and aircraft and addressed issues of military organisation. Britain's Royal Navy would soon introduce
570-786: A catastrophe for the Russian military in general and the Russian Navy in particular. Although neither party lacked courage, the Russians were defeated by the Japanese in the Battle of Port Arthur, which was the first time in warfare that mines were used for offensive purposes. The warships of the Baltic Fleet sent to the Far East were lost in the Battle of Tsushima. A further step change in naval firepower occurred when
684-628: A full military structure. For example, the UK's Anti-Aircraft Command, commanded by a full British Army general was part of ADGB. At its peak in 1941–42 it comprised three AA corps with 12 AA divisions between them. The use of balloons by the U.S. Army during the American Civil War compelled the Confederates to develop methods of combating them. These included the use of artillery, small arms, and saboteurs. They were unsuccessful, and internal politics led
798-404: A group, which may be a small squadron of comparable ships, or a larger naval fleet of various specialized ships. The commander of a fleet travels in the flagship , which is usually the most powerful vessel in the group. Before radio was invented, commands from the flagship were communicated by means of flags. At night signal lamps could be used for a similar purpose. Later these were replaced by
912-437: A large number of cannon made oar-based propulsion impossible, and ships came to rely primarily on sails . Warships were designed to carry increasing numbers of cannon and naval tactics evolved to bring a ship's firepower to bear in a broadside , with ships-of-the-line arranged in a line of battle . The development of large capacity, sail-powered ships carrying cannon led to a rapid expansion of European navies, especially
1026-451: A large traverse that could be easily transported on a wagon. Krupp 75 mm guns were supplied with an optical sighting system that improved their capabilities. The German Army also adapted a revolving cannon that came to be known to Allied fliers as the " flaming onion " from the shells in flight. This gun had five barrels that quickly launched a series of 37 mm artillery shells. As aircraft started to be used against ground targets on
1140-573: A major naval power in the mid-17th century in the first Anglo-Dutch war with a technical victory. Successive decisive Dutch victories in the second and third Anglo-Dutch Wars confirmed the Dutch mastery of the seas during the Dutch Golden Age , financed by the expansion of the Dutch Empire . The French Navy won some important victories near the end of the 17th century but a focus upon land forces led to
1254-543: A maritime force against attacks by airborne weapons launched from aircraft, ships, submarines and land-based sites". In some armies the term all-arms air defence (AAAD) is used for air defence by nonspecialist troops. Other terms from the late 20th century include "ground based air defence" (GBAD) with related terms " short range air defense " (SHORAD) and man-portable air-defense system (MANPADS). Anti-aircraft missiles are variously called surface-to-air missiles , ("SAMs") and surface-to-air guided weapons (SAGWs). Examples are
SECTION 10
#17328550826411368-682: A military fleet, although the term " merchant navy " for a commercial fleet still incorporates the non-military word sense . This overlap in word senses between commercial and military fleets grew out of the inherently dual-use nature of fleets; centuries ago, nationality was a trait that unified a fleet across both civilian and military uses. Although nationality of commercial vessels has little importance in peacetime trade other than for tax avoidance , it can have greater meaning during wartime, when supply chains become matters of patriotic attack and defense, and when in some cases private vessels are even temporarily converted to military vessels. The latter
1482-801: A navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes , deter or confront piracy , ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles . Naval operations can be broadly divided between riverine and littoral applications ( brown-water navy ), open-ocean applications ( blue-water navy ), and something in between ( green-water navy ), although these distinctions are more about strategic scope than tactical or operational division. First attested in English in
1596-504: A new 3.6-inch gun, in 1918. In 1928 a 3.7-inch (94 mm) gun became the preferred solution, but it took six years to gain funding. Production of the QF 3.7-inch gun began in 1937; this gun was used on mobile carriages with the field army and transportable guns on fixed mountings for static positions. At the same time the Royal Navy adopted a new 4.5-inch (113 mm) gun in a twin turret, which
1710-624: A new field mounting was introduced in 1916. Since most attacks were at night, searchlights were soon used, and acoustic methods of detection and locating were developed. By December 1916 there were 183 AA sections defending Britain (most with the 3-inch), 74 with the BEF in France and 10 in the Middle East. AA gunnery was a difficult business. The problem was of successfully aiming a shell to burst close to its target's future position, with various factors affecting
1824-666: A par with the army, navy, or air force. In the Soviet Union, this was called Voyska PVO , and had both fighter aircraft, separate from the air force, and ground-based systems. This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces. Subsequently, these became part of
1938-458: A single ship or aspect of a ship. However, commodores can also be temporary or honorary positions. For example, during World War II, a Navy captain was assigned duty as a convoy commodore, which meant that he was still a captain, but in charge of all the merchant vessels in the convoy. The most senior rank employed by a navy will tend to vary depending on the size of a navy and whether it is wartime or peacetime, for example, few people have ever held
2052-1206: Is an integral part of the navy but there are variations such as the French Troupes de marine , which is actually part of the French Army . The United States Marine Corps is a separate armed service within the United States Department of the Navy, with its own leadership structure. Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. In World War I, several navies used floatplanes and flying boats – mainly for scouting . By World War II, aircraft carriers could carry bomber aircraft capable of attacking naval and land targets, as well as fighter aircraft for defence. Since World War II helicopters have been embarked on smaller ships in roles such as anti-submarine warfare and transport. Some navies have also operated land-based aircraft in roles such as maritime patrol and training . Naval aviation forces primarily perform naval roles at sea. However, they are also used in
2166-475: Is assisted but not governed by identification friend or foe (IFF) electronic devices originally introduced during the Second World War . While these rules originate at the highest authority, different rules can apply to different types of air defence covering the same area at the same time. AAAD usually operates under the tightest rules. NATO calls these rules "weapon control orders" (WCO), they are: Until
2280-472: Is currently building one aircraft carrier, INS Vikrant , and considering another. France is also looking at a new carrier , probably using a CATOBAR system and possibly based on the British Queen Elizabeth design. A navy typically operates from one or more naval bases . The base is a port that is specialized in naval operations, and often includes housing, a munitions depot , docks for
2394-631: Is deployed in several ways: Air defence has included other elements, although after the Second World War most fell into disuse: Passive air defence is defined by NATO as "Passive measures taken for the physical defence and protection of personnel, essential installations and equipment in order to minimise the effectiveness of air and/or missile attack". It remains a vital activity by ground forces and includes camouflage and concealment to avoid detection by reconnaissance and attacking aircraft. Measures such as camouflaging important buildings were common in
SECTION 20
#17328550826412508-454: Is operated by specialists, batteries may have several dozen teams deploying separately in small sections; self-propelled air defence guns may deploy in pairs. Batteries are usually grouped into battalions or equivalent. In the field army, a light gun or SHORAD battalion is often assigned to a manoeuvre division. Heavier guns and long-range missiles may be in air-defence brigades and come under corps or higher command. Homeland air defence may have
2622-709: Is that boats are capable of being carried by ships. (Submarines by this rule are ships rather than boats, but are customarily referred to as boats reflecting their previous smaller size.) Navies use many types of boat, ranging from 9-foot (2.7 m) dinghies to 135-foot (41 m) landing craft. They are powered by either diesel engines, out-board gasoline engines, or waterjets. Most boats are built of aluminum, fiberglass, or steel. Rigid-hulled inflatable boats are also used. Patrol boats are used for patrols of coastal areas, lakes and large rivers. Landing craft are designed to carry troops, vehicles, or cargo from ship to shore under combat conditions, to unload, to withdraw from
2736-429: Is the branch of a nation's armed forces principally designated for naval and amphibious warfare ; namely, lake -borne, riverine , littoral , or ocean -borne combat operations and related functions. It includes anything conducted by surface ships , amphibious ships, submarines , and seaborne aviation , as well as ancillary support, communications, training, and other fields. The strategic offensive role of
2850-462: Is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action". It encompasses surface-based, subsurface ( submarine-launched ), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons ). It may be used to protect naval , ground , and air forces in any location. However, for most countries,
2964-414: Is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account
3078-573: Is usually accomplished via the combined use of systems optimized for either short-, medium-, or long-range air defence. In some countries, such as Britain and Germany during the Second World War , the Soviet Union , and modern NATO and the United States, ground-based air defence and air defence aircraft have been under integrated command and control. However, while overall air defence may be for homeland defence (including military facilities), forces in
3192-425: The 13-pr QF 9 cwt and these proved much more satisfactory. However, in general, these ad hoc solutions proved largely useless. With little experience in the role, no means of measuring target, range, height or speed the difficulty of observing their shell bursts relative to the target gunners proved unable to get their fuse setting correct and most rounds burst well below their targets. The exception to this rule
3306-505: The American Expeditionary Force (AEF) was created at Arnouville-Les-Gonesse where an antiaircraft school was established. The antiaircraft units were organized as serially numbered battalions during the war, as follows: In 1938 there were only six Regular Army and thirteen National Guard regiments, but by 1941 this had been expanded to 37 total regiments. In November 1942, 781 battalions were authorized. However, this number
3420-580: The FIM-92 Stinger missile. The Air Defense Artillery branch descended from Anti-Aircraft Artillery (part of the U.S. Army Coast Artillery Corps until 1950, then part of the Artillery Branch ) into a separate branch on 20 June 1968. On 1 December 1968, the ADA branch was authorized to wear modified Artillery insignia, crossed field guns with missile. The Branch Motto, "First To Fire", was adopted in 1986 by
3534-458: The QF 3-inch and QF 4-inch AA guns and also had Vickers 1-pounder quick firing "pom-poms" that could be used in various mountings. The first US anti-aircraft cannon was a 1-pounder concept design by Admiral Twining in 1911 to meet the perceived threat of airships, that eventually was used as the basis for the US Navy's first operational anti-aircraft cannon: the 3-inch/23 caliber gun .

3648-597: The RIM-66 Standard , Raytheon Standard Missile 6 , or the MBDA Aster missile. Non-English terms for air defence include the German Flak or FlaK ( Fliegerabwehrkanone , 'aircraft defence cannon', also cited as Flugabwehrkanone ), whence English flak , and the Russian term Protivovozdushnaya oborona ( Cyrillic : Противовозду́шная оборо́на), a literal translation of 'anti-air defence', abbreviated as PVO. In Russian,
3762-653: The Royal Naval Volunteer Reserve (RNVR) was manning AA guns and searchlights assembled from various sources at some nine ports. The Royal Garrison Artillery (RGA) was given responsibility for AA defence in the field, using motorised two-gun sections. The first were formally formed in November 1914. Initially they used QF 1-pounder "pom-pom"s (37 mm versions of the Maxim Gun ). All armies soon deployed AA guns often based on their smaller field pieces, notably
3876-570: The Spanish and Portuguese navies that dominated in the 16th and early 17th centuries, and helped propel the age of exploration and colonialism . The repulsion of the Spanish Armada (1588) by the English fleet revolutionized naval warfare by the success of a guns-only strategy and caused a major overhaul of the Spanish Navy , partly along English lines, which resulted in even greater dominance by
3990-658: The United States Air Force 's operating bases in the UK. All ground-based air defence was removed from Royal Air Force (RAF) jurisdiction in 2004 . The British Army's Anti-Aircraft Command was disbanded in March 1955, but during the 1960s and 1970s the RAF's Fighter Command operated long-range air-defence missiles to protect key areas in the UK. During World War II, the Royal Marines also provided air defence units; formally part of
4104-537: The oiler , minesweeper , patrol boat , hydrographic and oceanographic survey ship and tender . During the age of sail , the ship categories were divided into the ship of the line , frigate, and sloop-of-war . Naval ship names are typically prefixed by an abbreviation indicating the national navy in which they serve. For a list of the prefixes used with ship names ( HMS , USS , LÉ , etc.) see ship prefix . Today's warships are significantly faster than in years past, thanks to much improved propulsion systems. Also,
4218-649: The 1950s, guns firing ballistic munitions were the standard weapon; guided missiles then became dominant, except at the very shortest ranges. However, the type of shell or warhead and its fuzing and, with missiles, the guidance arrangement were and are varied. Targets are not always easy to destroy; nonetheless, damaged aircraft may be forced to abort their mission and, even if they manage to return and land in friendly territory, may be out of action for days or permanently. Ignoring small arms and smaller machine-guns, ground-based air defence guns have varied in calibre from 20 mm to at least 152 mm. Ground-based air defence
4332-465: The 30th of September, 1915, troops of the Serbian Army observed three enemy aircraft approaching Kragujevac . Soldiers fired at them with shotguns and machine-guns but failed to prevent them from dropping 45 bombs over the city, hitting military installations, the railway station and many other, mostly civilian, targets in the city. During the bombing raid, private Radoje Ljutovac fired his cannon at
4446-420: The 8.8 cm FlaK 18 in 1933, the 36 and 37 models followed with various improvements, but ballistic performance was unchanged. In the late 1930s the 10.5 cm FlaK 38 appeared, soon followed by the 39; this was designed primarily for static sites but had a mobile mounting, and the unit had 220 V 24 kW generators. In 1938 design started on the 12.8 cm FlaK . Britain had successfully tested
4560-484: The AA systems are called zenitnye (i.e., 'pointing to zenith ') systems. In French, air defence is called Défense contre les aéronefs (DCA) , aéronef meaning 'aircraft'. The maximum distance at which a gun or missile can engage an aircraft is an important figure. However, many different definitions are used and unless the same definition is used, performance of different guns or missiles cannot be compared. For AA guns only
4674-713: The AAA school was moved to Fort Bliss . Army Air Defense Command ran from 1957 to 1974. In 1991 the Patriot missile was heavily utilized during the Gulf War. After this short skirmish ended Air Defense has not been involved in any significant combat actions due to lack of enemy air assets and/or missile technology. In 2010 the United States Army Air Defense Artillery School was moved from Fort Bliss to Fort Sill . The following lists all units that make up

4788-567: The Army's Air Defense Artillery Branch. The Shipton Award is named for Brigadier General James A. Shipton , who is acknowledged as the Air Defense Artillery Branch's founding father. Shipton felt that the mission of antiaircraft defense was not to down enemy aircraft, but instead to protect maneuver forces on the ground: "The purpose of anti-aviation defense is to protect our forces and establishments from hostile attack and observation from
4902-485: The British Isles increased in 1915 and the AA efforts were deemed somewhat ineffective, so a Royal Navy gunnery expert, Admiral Sir Percy Scott , was appointed to make improvements, particularly an integrated AA defence for London. The air defences were expanded with more RNVR AA guns, 75 mm and 3-inch, the pom-poms being ineffective. The naval 3-inch was also adopted by the army, the QF 3-inch 20 cwt (76 mm),
5016-534: The British adopted a new instrument developed by Vickers. It was a mechanical analogue computer - the Predictor AA No 1. Given the target height, its operators tracked the target and the predictor produced bearing, quadrant elevation and fuse setting. These were passed electrically to the guns, where they were displayed on repeater dials to the layers who "matched pointers" (target data and the gun's actual data) to lay
5130-468: The French 75 mm and Russian 76.2 mm, typically simply propped up on some sort of embankment to get the muzzle pointed skyward. The British Army adopted the 13-pounder quickly producing new mountings suitable for AA use, the 13-pdr QF 6 cwt Mk III was issued in 1915. It remained in service throughout the war but 18-pdr guns were lined down to take the 13-pdr shell with a larger cartridge producing
5244-626: The French Navy's relative neglect, which allowed the Royal Navy to emerge with an ever-growing advantage in size and quality, especially in tactics and experience, from 1695. As a response to growing naval influence of the navies of Portuguese, the warrior king of the Marathas, Shivaji laid the foundation of the Maratha navy in 1654. Throughout the 18th century the Royal Navy gradually gained ascendancy over
5358-601: The French Navy, with victories in the War of Spanish Succession (1701–1714), inconclusive battles in the War of Austrian Succession (1740–1748), victories in the Seven Years' War (1754–1763), a partial reversal during the American War of Independence (1775–1783), and consolidation into uncontested supremacy during the 19th century from the Battle of Trafalgar in 1805. These conflicts saw

NATO defines anti-aircraft warfare (AAW) as "measures taken to defend
5586-468: The Second World War. During the Cold War the runways and taxiways of some airfields were painted green. While navies are usually responsible for their own air defence—at least for ships at sea—organisational arrangements for land-based air defence vary between nations and over time. The most extreme case was the Soviet Union and this model may still be followed in some countries: it was a separate service, on
5700-745: The Spanish. From the beginning of the 17th century the Dutch cannibalized the Portuguese Empire in the East and, with the immense wealth gained, challenged Spanish hegemony at sea. From the 1620s, Dutch raiders seriously troubled Spanish shipping and, after a number of battles that went both ways, the Dutch Navy finally broke the long dominance of the Spanish Navy in the Battle of the Downs (1639). England emerged as
5814-533: The U.S. Navy lifted the ban in April 2010. The major reasons historically cited by the U.S. Navy were the extended duty tours and close conditions which afford almost no privacy. The United Kingdom's Royal Navy has had similar restrictions. Australia, Canada, Norway, and Spain previously opened submarine service to women sailors. A navy will typically have two sets of ranks, one for enlisted personnel and one for officers . Typical ranks for commissioned officers include

#17328550826415928-560: The United Kingdom launched HMS Dreadnought in 1906, but naval tactics still emphasized the line of battle. The first practical military submarines were developed in the late 19th century and by the end of World War I had proven to be a powerful arm of naval warfare. During World War II , Nazi Germany 's submarine fleet of U-boats almost starved the United Kingdom into submission and inflicted tremendous losses on U.S. coastal shipping . The German battleship Tirpitz ,

Turks carried out the first ever anti-airplane operation in history during the Italo-Turkish war . Although lacking anti-aircraft weapons, they were the first to shoot down an airplane by rifle fire. The first aircraft to crash in a war was the one of Lieutenant Piero Manzini, shot down on August 25, 1912. The earliest known use of weapons specifically made for

6270-587: The air force and ground forces respectively. At the other extreme, the United States Army has an Air Defense Artillery Branch that provides ground-based air defence for both homeland and the army in the field; however, it is operationally under the Joint Force Air Component Commander . Many other nations also deploy an air-defence branch in the army. Some, such as Japan or Israel, choose to integrate their ground based air defence systems into their air force. In Britain and some other armies,
6384-413: The altitude at which a gun could deliver a series of shells against a moving target; this could be constrained by maximum fuse running time as well as the gun's capability. By the late 1930s the British definition was "that height at which a directly approaching target at 400 mph [640 km/h] can be engaged for 20 seconds before the gun reaches 70 degrees elevation". The essence of air defence
6498-545: The anti-aircraft role occurred during the Franco-Prussian War of 1870. After the disaster at Sedan , Paris was besieged and French troops outside the city started an attempt at communication via balloon . Gustav Krupp mounted a modified 1-pounder (37 mm) gun – the Ballonabwehrkanone (Balloon defence cannon) or BaK — on top of a horse-drawn carriage for the purpose of shooting down these balloons. By
6612-494: The army adopted in simplified single-gun mountings for static positions, mostly around ports where naval ammunition was available. The performance of the new guns was limited by their standard fuse No 199, with a 30-second running time, although a new mechanical time fuse giving 43 seconds was nearing readiness. In 1939 a machine fuse setter was introduced to eliminate manual fuse setting. Naval A navy , naval force , military maritime fleet , war navy , or maritime force
6726-407: The ascending part of the trajectory can be usefully used. One term is "ceiling", the maximum ceiling being the height a projectile would reach if fired vertically, not practically useful in itself as few AA guns are able to fire vertically, and the maximum fuse duration may be too short, but potentially useful as a standard to compare different weapons. The British adopted "effective ceiling", meaning

The motto refers to a speech given by General Jonathan Wainwright to veterans of the 200th Coast Artillery (Antiaircraft) stating they were the 'First to Fire' in World War II against the Empire of Japan. According to the Army's Field Manual 3-01, the mission of Air Defense Artillery is "to protect the force and selected geopolitical assets from aerial attack, missile attack, and surveillance."

Soon the forces were adding various machine-gun based weapons mounted on poles. These short-range weapons proved more deadly, and the " Red Baron " is believed to have been shot down by an anti-aircraft Vickers machine gun . When

They will typically have a power-operated bow ramp, a cargo well and after structures that house engine rooms, pilot houses, and stowage compartments. These boats are sometimes carried by larger ships. Special operations craft are high-speed craft used for insertion and extraction of special forces personnel and some may be transportable (and deployed) by air. Boats used in non-combat roles include lifeboats, mail boats, line handling boats, buoy boats, aircraft rescue boats, torpedo retrievers, explosive ordnance disposal craft, utility boats, dive boats, targets, and work boats. Boats are also used for survey work, tending divers, and minesweeping operations. Boats for carrying cargo and personnel are sometimes known as launches, gigs, barges or shore party boats. Naval forces are typically arranged into units based on

Regional powers may maintain a " green water navy " as a means of localized force projection. Blue water fleets may require specialized vessels, such as minesweepers , when operating in the littoral regions along the coast. A basic tradition is that all ships commissioned in a navy are referred to as ships rather than vessels, with
7296-408: The competition for a share of limited defence budgets. Demobilisation meant that most AA guns were taken out of service, leaving only the most modern. However, there were lessons to be learned. In particular the British, who had had AA guns in most theatres in action in daylight and used them against night attacks at home. Furthermore, they had also formed an Anti-Aircraft Experimental Section during
7410-539: The development and refinement of tactics that came to be called the line of battle . The next stage in the evolution of naval warfare was the introduction of metal plating along the hull sides. The increased mass required steam-powered engines, resulting in an arms race between armor and weapon thickness and firepower. The first armored vessels, the French Gloire and British HMS Warrior , made wooden vessels obsolete. Another significant improvement came with
7524-782: The early 14th century, the word "navy" came via Old French navie , "fleet of ships", from the Latin navigium , "a vessel, a ship, bark, boat", from navis , "ship". The word "naval" came from Latin navalis , "pertaining to ship"; cf. Greek ναῦς ( naus ), "ship", ναύτης ( nautes ), "seaman, sailor". The earliest attested form of the word is in the Mycenaean Greek compound word 𐀙𐀄𐀈𐀗 , na-u -do-mo (* naudomoi ), "shipbuilders", written in Linear B syllabic script. The word formerly denoted fleets of both commercial and military nature. In modern usage "navy" used alone always denotes
7638-674: The early 20th century balloon, or airship, guns, for land and naval use were attracting attention. Various types of ammunition were proposed, high explosive, incendiary, bullet-chains, rod bullets and shrapnel. The need for some form of tracer or smoke trail was articulated. Fuzing options were also examined, both impact and time types. Mountings were generally pedestal type but could be on field platforms. Trials were underway in most countries in Europe but only Krupp, Erhardt, Vickers Maxim, and Schneider had published any information by 1910. Krupp's designs included adaptations of their 65 mm 9-pounder,
7752-404: The efficiency of the engines has improved, in terms of fuel, and of how many sailors it takes to operate them. In World War II, ships needed to refuel very often. However, today ships can go on very long journeys without refueling. Also, in World War II, the engine room needed about a dozen sailors to work the many engines, however, today, only about four or five are needed (depending on the class of
7866-482: The enemy aircraft and successfully shot one down. It crashed in the city and both pilots died from their injuries. The cannon Ljutovac used was not designed as an anti-aircraft gun; it was a slightly modified Turkish cannon captured during the First Balkan War in 1912. This was the first occasion in military history that a military aircraft was shot down with ground-to-air artillery fire. The British recognised
7980-602: The enemy vessel so its occupants could be attacked hand-to-hand. Naval warfare continued in this vein through the Middle Ages until the cannon became commonplace and capable of being reloaded quickly enough to be reused in the same battle. In ancient China , large naval battles were known since the Qin dynasty ( also see Battle of Red Cliffs , 208), employing the war junk during the Han dynasty . However, China's first official standing navy
8094-449: The era of the Roman empire , naval forces included marine legionaries for maritime boarding actions . These were troops primarily trained in land warfare, and did not need to be skilled at handling a ship. Much later during the age of sail, a component of marines served a similar role, being ship-borne soldiers who were used either during boarding actions, as sharp-shooters, or in raids along shorelines. The Spanish Infantería de Marina
8208-417: The exception of destroyers and submarines, which are known as boats. The prefix on a ship's name indicates that it is a commissioned ship. An important tradition on board naval vessels of some nations has been the ship's bell . This was historically used to mark the passage of time, as warning devices in heavy fog, and for alarms and ceremonies. The ship's captain, and more senior officers are "piped" aboard
8322-654: The field, wherever they are, provide their own defences against airborne threats. Until the 1950s, guns firing ballistic munitions ranging from 7.62 mm (.30 in) to 152.4 mm (6 in) were the standard weapons; guided missiles then became dominant, except at the very shortest ranges (as with close-in weapon systems , which typically use rotary autocannons or, in very modern systems, surface-to-air adaptations of short-range air-to-air missiles , often combined in one system with rotary cannons). It may also be called counter-air , anti-air , AA , flak , layered air defence or air defence forces . The term air defence
8436-451: The following, in ascending order ( Commonwealth ranks are listed first on each line; USA ranks are listed second in those instances where they differ from Commonwealth ranks): "Flag officers" include any rank that includes the word "admiral" (or commodore in services other than the US Navy), and are generally in command of a battle group , strike group or similar flotilla of ships, rather than
8550-578: The ground-based air defence of the British Army's Anti-Aircraft Command , although field-deployed air defence relied on less sophisticated arrangements. NATO later called these arrangements an "air defence ground environment", defined as "the network of ground radar sites and command and control centres within a specific theatre of operations which are used for the tactical control of air defence operations". Rules of engagement are critical to prevent air defences engaging friendly or neutral aircraft. Their use
8664-579: The guns. This system of repeater electrical dials built on the arrangements introduced by British coast artillery in the 1880s, and coast artillery was the background of many AA officers. Similar systems were adopted in other countries and for example the later Sperry M3A3 in the US, was also used by Britain as the Predictor AA No 2. Height finders were also increasing in size; in Britain, the seven-foot optical base World War I Barr & Stroud UB 2 stereoscopic rangefinder
8778-527: The invention of the rotating turrets, which allowed the guns to be aimed independently of ship movement. The battle between CSS Virginia and USS Monitor during the American Civil War (1861–1865) is often cited as the beginning of this age of maritime conflict. The Russian Navy was considered the third strongest in the world on the eve of the Russo-Japanese War , which turned to be
8892-494: The late 1930s for development work on sound-locating acoustic devices to be generally halted, although equipment was retained. Furthermore, in Britain the volunteer Observer Corps formed in 1925 provided a network of observation posts to report hostile aircraft flying over Britain. Initially radar was used for airspace surveillance to detect approaching hostile aircraft. However, the German Würzburg radar put into use in 1940
9006-601: The main effort has tended to be homeland defence . Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles ). ‘Layered air defence’ usually refers to multiple ‘tiers’ of air defence systems which, when combined, an airborne threat must penetrate in order to reach its target; This defence
9120-513: The mobile naval base defence organisation, they were handled as an integral part of the army-commanded ground based air defences. The basic air defence unit is typically a battery with 2 to 12 guns or missile launchers and fire control elements. These batteries, particularly with guns, usually deploy in a small area, although batteries may be split; this is usual for some missile systems. SHORAD missile batteries often deploy across an area with individual launchers several kilometres apart. When MANPADS
9234-487: The need for anti-aircraft capability a few weeks before World War I broke out; on 8 July 1914, the New York Times reported that the British government had decided to "dot the coasts of the British Isles with a series of towers, each armed with two quick-firing guns of special design," while "a complete circle of towers" was to be built around "naval installations" and "at other especially vulnerable points". By December 1914
9348-458: The number of ships included, a single ship being the smallest operational unit. Ships may be combined into squadrons or flotillas , which may be formed into fleets . The largest unit size may be the whole Navy or Admiralty . A task force can be assembled using ships from different fleets for an operational task. Despite their acceptance in many areas of naval service, female sailors were not permitted to serve on board U.S. submarines until
9462-416: The numerous United States carrier battle groups . Only two nations, the United States and France , presently operate CATOBAR carriers of any size, while Russia , China and India operate sizeable STOBAR carriers (although all three are originally of Russian design). The United Kingdom is also operating two Queen Elizabeth -class carriers, which are the largest STOVL vessels in service, and India
9576-432: The prow of the ship. Firing a cannon salute partially disarms the ship, so firing a cannon for no combat reason showed respect and trust. As the tradition evolved, the number of cannons fired became an indication of the rank of the official being saluted. Historically, navy ships were primarily intended for warfare. They were designed to withstand damage and to inflict the same, but only carried munitions and supplies for
9690-418: The radio transmitter, or the flashing light when radio silence was needed. A " blue water navy " is designed to operate far from the coastal waters of its home nation. These are ships capable of maintaining station for long periods of time in deep ocean, and will have a long logistical tail for their support. Many are also nuclear powered to save having to refuel. By contrast a " brown water navy " operates in
9804-627: The rank of Fleet Admiral in the U.S. Navy, the chief of the Royal Australian Navy holds the rank of Vice Admiral, and the chief of the Irish Naval Service holds the rank of Commodore. Naval infantry, commonly known as marines , are a category of infantry that form part of a state's naval forces and perform roles on land and at sea, including amphibious operations , as well as other, naval roles. They also perform other tasks, including land warfare, separate from naval operations. During
9918-715: The seafaring local people (either Malays of Srivijaya or Javanese of Mataram ) to attack as far as the coast of Tanzania and Mozambique with 1000 boats and attempted to take the citadel of Qanbaloh, about 7,000 km to their West, in 945–946 AD. In 1350 AD Majapahit launched its largest military expedition, the invasion of Pasai , with 400 large jong and innumerable smaller vessels. The second largest military expedition, invasion of Singapura in 1398, Majapahit deployed 300 jong with no less than 200,000 men. The average jong used by Majapahit would be about 76.18–79.81 m LOA , carrying 600–700 men, with 1200–1400 tons deadweight . The mass and deck space required to carry
10032-461: The shells' predicted trajectory. This was called deflection gun-laying, where "off-set" angles for range and elevation were set on the gunsight and updated as their target moved. In this method, when the sights were on the target, the barrel was pointed at the target's future position. Range and height of the target determined fuse length. The difficulties increased as aircraft performance improved. The British dealt with range measurement first, when it
10146-494: The ship using a Boatswain's call . In the United States, the First Navy Jack is a flag that has the words, "Don't Tread on Me" on the flag. By English tradition, ships have been referred to as a "she". However, it was long considered bad luck to permit women to sail on board naval vessels. To do so would invite a terrible storm that would wreck the ship. The only women that were welcomed on board were figureheads mounted on
10260-507: The ship). Today, naval strike groups on longer missions are always followed by a range of support and replenishment ships supplying them with anything from fuel and munitions, to medical treatment and postal services. This allows strike groups and combat ships to remain at sea for several months at a time. The term "boat" refers to small craft limited in their use by size and usually not capable of making lengthy independent voyages at sea. The old navy adage to differentiate between ships and boats
10374-569: The single artillery branch has been responsible for both home and overseas ground-based air defence, although there was divided responsibility with the Royal Navy for air defence of the British Isles in World War I . However, during the Second World War , the RAF Regiment was formed to protect airfields everywhere, and this included light air defences. In the later decades of the Cold War this included
10488-477: The speed and direction of both the target and the projectile. Throughout the 20th century, air defence was one of the fastest-evolving areas of military technology, responding to the evolution of aircraft and exploiting technology such as radar, guided missiles and computing (initially electromechanical analogue computing from the 1930s on, as with equipment described below). Improvements were made to sensors, technical fire control, weapons, and command and control. At
10602-422: The start of the 20th century these were either very primitive or non-existent. Initially sensors were optical and acoustic devices developed during World War I and continued into the 1930s, but were quickly superseded by radar, which in turn was supplemented by optoelectronics in the 1980s. Command and control remained primitive until the late 1930s, when Britain created an integrated system for ADGB that linked
10716-463: The target and having its height. Second, that the target would maintain a steady course, speed and height. This HAA was to engage targets up to 24,000 ft (7.3 km). Mechanical time fuses were required because the speed of powder burning varied with height, so fuse length was not a simple function of time of flight. Automated fire ensured a constant rate of fire that made it easier to predict where each shell should be individually aimed. In 1925
10830-400: The vessels, and various repair facilities. During times of war temporary bases may be constructed in closer proximity to strategic locations, as it is advantageous in terms of patrols and station-keeping. Nations with historically strong naval forces have found it advantageous to obtain basing rights in other countries in areas of strategic interest. Navy ships can operate independently or with
10944-695: The voyage (rather than merchant cargo). Often, other ships that were not built specifically for warfare, such as the galleon or the armed merchant ships in World War II , did carry armaments. In more recent times, navy ships have become more specialized and have included supply ships, troop transports, repair ships, oil tankers and other logistics support ships as well as combat ships. Modern navy combat ships are generally divided into seven main categories: aircraft carriers , cruisers , destroyers , frigates , corvettes , submarines , and amphibious assault ships . There are also support and auxiliary ships, including
11058-409: The war and accumulated large amounts of data that was subjected to extensive analysis. As a result, they published the two-volume Textbook of Anti-Aircraft Gunnery in 1924–1925. It included five key recommendations for HAA equipment: Two assumptions underpinned the British approach to HAA fire; first, aimed fire was the primary method and this was enabled by predicting gun data from visually tracking
11172-437: The war ended, it was clear that the increasing capabilities of aircraft would require better means of acquiring targets and aiming at them. Nevertheless, a pattern had been set: anti-aircraft warfare would employ heavy weapons to attack high-altitude targets and lighter weapons for use when aircraft came to lower altitudes. World War I demonstrated that aircraft could be an important part of the battlefield, but in some nations it
11286-575: The world's total numbers and total tonnage of naval vessels of 1,000 tons or greater. Throughout the rest of the 20th century, the United States Navy would maintain a tonnage greater than that of the next 17 largest navies combined. During the Cold War , the Soviet Navy became a significant armed force, with large numbers of large, heavily armed ballistic missile submarines and extensive use of heavy, long-ranged antisurface missiles to counter
11400-440: The years immediately after World War I, the prospect of another major war seemed remote, particularly in Europe, where the most militarily capable nations were, and little financing was available. Four years of war had seen the creation of a new and technically demanding branch of military activity. Air defence had made huge advances, albeit from a very low starting point. However, it was new and often lacked influential 'friends' in
11514-458: Was arguably the largest naval battle in history ; it was also the last battle in which battleships played a significant role. By the end of World War II , the carrier had become the dominant force of naval warfare. World War II also saw the United States become by far the largest naval power in the world. In the late 20th and early 21st centuries, the United States Navy possessed over 70% of
11628-571: Was capable of providing data suitable for controlling AA guns, and the British Radar, Gun Laying, Mark I , was designed to be used on AA gun positions and was in use by 1939. The Treaty of Versailles prevented Germany having AA weapons, and for example, the Krupps designers joined Bofors in Sweden. Some World War I guns were retained and some covert AA training started in the late 1920s. Germany introduced
11742-581: Was determined by time of flight, but the burning rate of the gunpowder was affected by altitude. The British pom-poms had only contact-fused ammunition. Zeppelins , being hydrogen-filled balloons, were targets for incendiary shells and the British introduced these with airburst fuses, both shrapnel type-forward projection of incendiary "pot" and base ejection of an incendiary stream. The British also fitted tracers to their shells for use at night. Smoke shells were also available for some AA guns, these bursts were used as targets during training. German air attacks on
11856-404: Was electrical; the operator entered the target range and had displays at guns; it was used with their 75 mm. The British Wilson-Dalby gun director used a pair of trackers and mechanical tachymetry; the operator entered the fuse length, and deflection angles were read from the instruments. By the start of World War I , the 77 mm had become the standard German weapon, and came mounted on
11970-482: Was especially important, and common, before 20th-century military technology existed, when merely adding artillery and naval infantry to any sailing vessel could render it fully as martial as any military-owned vessel. Such privateering has been rendered obsolete in blue-water strategy since modern missile and aircraft systems grew to leapfrog over artillery and infantry in many respects; but privateering nevertheless remains potentially relevant in littoral warfare of
12084-411: Was formed in 1537, making it the oldest, current marine force in the world. The British Royal Marines combine being both a ship-based force and also being specially trained in commando frogman -style operations and tactics, operating in some cases separately from the rest of the Royal Navy. The Royal Marines also have their own special forces unit . In the majority of countries, the marine force
12198-595: Was not established until the Southern Song dynasty in the 12th century, a time when gunpowder was a revolutionary new application to warfare. The Chola Dynasty in Southern India had a navy composed of trade ships transporting armies overseas. The Chola Navy reached its peak under Rajendra I , and was most notably used in invasions of Sri Lanka and Southeast Asia . Nusantaran thalassocracies made extensive use of naval power and technologies. This enabled
12312-457: Was pared down to 331 battalions by the end of the war. By late 1944 the regiments had been broken up into battalions and 144 "Antiaircraft Artillery Groups" had been activated; some of these existed only briefly. The serially-numbered battalions in late World War II included the following types: and in the 1950s: On 9 March 1942 Antiaircraft Command was established in Washington D.C. and 1944
12426-575: Was probably first used by the UK when Air Defence of Great Britain (ADGB) was created as a Royal Air Force command in 1925. However, arrangements in the UK were also called "anti-aircraft", abbreviated as AA , a term that remained in general use into the 1950s. After the First World War it was sometimes prefixed by "light" or "heavy" (LAA or HAA) to classify a type of gun or unit. Nicknames for anti-aircraft guns include "AA", "AAA" or "triple-A" (abbreviations of "anti-aircraft artillery"), "flak" (from
12540-472: Was realised that range was the key to producing a better fuse setting. This led to the height/range finder (HRF), the first model being the Barr & Stroud UB2, a two-metre optical coincident rangefinder mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF
12654-572: Was replaced by the nine-foot optical base UB 7 and the eighteen-foot optical base UB 10 (only used on static AA sites). Goertz in Germany and Levallois in France produced five m (16 ft) instruments. However, in most countries the main effort in HAA guns until the mid-1930s was improving existing ones, although various new designs were on drawing boards. From the early 1930s eight countries developed radar ; these developments were sufficiently advanced by
12768-551: Was soon joined by the height/fuse indicator (HFI), this was marked with elevation angles and height lines overlaid with fuse length curves, using the height reported by the HRF operator, the necessary fuse length could be read off. However, the problem of deflection settings — "aim-off" — required knowing the rate of change in the target's position. Both France and the UK introduced tachymetric devices to track targets and produce vertical and horizontal deflection angles. The French Brocq system
12882-501: Was the guns protecting spotting balloons, in which case the altitude could be accurately measured from the length of the cable holding the balloon. The first issue was ammunition. Before the war it was recognised that ammunition needed to explode in the air. Both high explosive (HE) and shrapnel were used, mostly the former. Airburst fuses were either igniferious (based on a burning fuse) or mechanical (clockwork). Igniferious fuses were not well suited for anti-aircraft use. The fuse length
12996-496: Was the prospect of strategic air attack that was the main issue, presenting both a threat and an opportunity. The experience of four years of air attacks on London by Zeppelins and Gotha G.V bombers had particularly influenced the British and was one of if not the main driver for forming an independent air force. As the capabilities of aircraft and their engines improved it was clear that their role in future war would be even more critical as their range and weapon load grew. However, in
