129-518: Developed as a successor to the AIM-9L Sidewinder , the AAM-3 improved target acquisition and tracking capabilities through more sensitive temperature difference detection, and improved flight manoeuvrability of the missile itself. Research began as early as 1974, but full-scale development only began in 1986 and entered service in 1991 ( Heisei 2). In 1974, Japan began limited development of

258-572: A SARH (semi-active radar homing) variant (AIM-9C) and an IR (AIM-9D) in 1963. The AIM-9C's semi-active radar was exclusively tied to the F-8 Crusader 's radar and fire control system (FCS). A total of around 1,000 AIM-9C missiles were launched from 1965 to 1967, but their usage in Vietnam war proved unsuccessful, downing no enemies. A filter modification program for reworked units (to allow high altitude capability up to 18,288m (60,000 feet) This

387-484: A naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict

516-515: A shuttle diplomacy mission from President Ronald Reagan to broker a peace deal based on an interim authority taking control of the islands pending negotiations. After hearing from Thatcher that the task force would not be withdrawn unless the Argentines evacuated their troops, Haig headed for Buenos Aires. There he met the junta and Nicanor Costa Méndez , the foreign minister. Haig was treated coolly and told that Argentine sovereignty must be

645-535: A solid rocket motor for propulsion, similar to most conventional missiles, a continuous-rod fragmentation warhead , and an infrared seeker . The seeker tracks a difference in temperatures detected and uses proportional guidance to achieve impact. Older variants such as the AIM-9B with uncooled seeker heads could only track the high temperatures of engine exhaust , making them strictly rear aspect. Later variants, however, featured liquid nitrogen coolant bottles in

774-635: A common topic for discussion. Diplomatic relations between the United Kingdom and Argentina were restored in 1989 following a meeting in Madrid , at which the two governments issued a joint statement. No change in either country's position regarding the sovereignty of the Falkland Islands was made explicit. In 1994, Argentina adopted a new constitution , which declared the Falkland Islands as part of one of its provinces by law. However,

903-721: A contract to support Sidewinder operations through to 2055. Air Force spokeswoman Stephanie Powell said that its relatively low cost, versatility, and reliability mean it is "very possible that the Sidewinder will remain in Air Force inventories through the late 21st century". The AIM-9 was a product of the US Naval Weapons Center at China Lake in the Mojave Desert . It features a lightweight, compact design with cruciform canards and tail fins. It uses

1032-603: A crisis meeting headed by Prime Minister Margaret Thatcher , the First Sea Lord and Chief of the Naval Staff , Admiral Sir Henry Leach , advised that "Britain could and should send a task force if the islands are invaded". On 1 April, Leach sent orders to a Royal Navy force carrying out exercises in the Mediterranean to prepare to sail south. Following the invasion on 2 April, after an emergency meeting of

1161-529: A heat-homing rocket. The name Sidewinder was selected in 1950 and is the common name of Crotalus cerastes , a rattlesnake , which uses infrared sensory organs to hunt warm-blooded prey. It did not receive official funding until 1951 when the effort was mature enough to show to Admiral William "Deak" Parsons , the Deputy Chief of the Bureau of Ordnance (BuOrd). It subsequently received designation as

1290-464: A mixture of surface-to-air missile (SAM) systems (Franco-German Roland and British Tigercat ) and light anti-aircraft guns, including Swiss-built Oerlikon 35 mm twin cannons and 30 mm Hispano-Suiza cannon and German Rheinmetall 20 mm twin anti-aircraft cannons . More of the anti-aircraft guns were deployed to the airstrip at Goose Green. Lockheed Hercules transport night flights brought supplies, weapons, vehicles, and fuel, and airlifted out

1419-780: A naval bombardment demonstration by two Royal Navy vessels ( Antrim and Plymouth ), the Argentine forces, a total of 190 men, surrendered without resistance to the Royal Marines. The message sent from the naval force at South Georgia to London was, "Be pleased to inform Her Majesty that the White Ensign flies alongside the Union Jack in South Georgia. God Save the Queen." The Prime Minister, Margaret Thatcher, broke

1548-531: A new UK Minister of State for Foreign Affairs , Nicholas Ridley , went to the Falklands trying to sell the islanders the benefits of a leaseback scheme, which met with strong opposition from the islanders. On his return to London in December 1980, he reported to parliament but was viciously attacked at what was seen as a sellout. (It was unlikely that leaseback idea would have progressed further anyway since

1677-705: A new nose dome and superior optical filtering. Conversions were done to European AIM-9B to upgrade them to the FGW.2 standard. The official designation is the AIM-9B FGW.2 but it is known as the AIM-9F in US nomenclature. The AIM-9G was very similar to the AIM-9D in most aspects, and did not differ externally. The AIM-9G was an AIM-9D that used an improved AIM-9D seeker head with SEAM (Sidewinder Extended Acquisition Mode), this allowed

1806-467: A pre-condition of any talks. Returning to London on 11 April, he found the British cabinet in no mood for compromise. Haig flew back to Washington before returning to Buenos Aires for a final protracted round of talks. These made little progress, but just as Haig and his mission were leaving, they were told that Galtieri would meet them at the airport VIP lounge to make an important concession; however, this

1935-642: A program in 1952. Originally called the Sidewinder 1 , the first live firing was on 3 September 1952. The missile intercepted a drone for the first time on 11 September 1953. The missile carried out 51 guided flights in 1954, and in 1955 production was authorized. In 1954, the US Air Force carried out trials with the original AIM-9A and the improved AIM-9B at the Holloman Air Development Center. The first operational use of

2064-484: A radio proximity fuze could be used. These improvements were all added into AIM-9D and went into service with the USN. Around 1,000 AIM-9D units were produced from 1965 to 1969. The primary problem of the AIM-9D was breakup during launch. The AIM-9D was eventually developed into AIM-9G. ATM-9D (USN) : AIM-9D used for captive flight target acquisition training. GDU-1/B : AIM-9D used for firing practice. The AIM-9E "Echo"

2193-644: A serious threat, and she was escorted by two modern Type 42 guided-missile destroyers , armed with Exocet missiles. On 1 May, the British nuclear-powered submarine HMS  Conqueror (one of three patrolling the TEZ) located the Belgrano group and followed it until the following day, when it was about 12 hours away from the Task Force and just outside the Total Exclusion Zone. Admiral Woodward

2322-526: A signal to the Argentines that the UK was unwilling, and would soon be unable, to defend its territories and subjects in the Falklands. On 2 April 1982, Argentine forces mounted amphibious landings, known as Operation Rosario, on the Falkland Islands. The invasion was met with a fierce but brief defence organised by the Falkland Islands' Governor Sir Rex Hunt , giving command to Major Mike Norman of

2451-420: A spinning disk with lines painted on it, alternately known as a "reticle" or "chopper". The reticle spun at a fixed speed, causing the output of the photocell to be interrupted in a pattern, and the precise timing of the resulting signal indicated the bearing of the target. Although Hamburg and similar devices like Madrid were essentially complete, the work of mating them to a missile had not been carried out by

2580-416: A submarine alert was sounded and operations were halted, with Tidespring being withdrawn to deeper water to avoid interception. On 24 April, British forces regrouped and headed in to attack. On 25 April, after resupplying the Argentine garrison in South Georgia, the submarine ARA  Santa Fe was spotted on the surface by a Westland Wessex HAS Mk 3 helicopter from HMS  Antrim , which attacked

2709-876: A wide variety of missile projects were underway, from huge systems like the Bell Bomi rocket-powered bomber to small systems like air-to-air missiles. By the early 1950s, both the US Air Force and Royal Air Force had started major IR seeker missile projects. The development of the Sidewinder missile began in 1946 at the Naval Ordnance Test Station (NOTS), Inyokern, California, now the Naval Air Weapons Station China Lake , as an in-house research project conceived by William B. McLean . McLean initially called his effort "Local Fuze Project 602" using laboratory funding, volunteer help and fuze funding to develop what they called

2838-547: Is a short-range air-to-air missile . Entering service with the United States Navy in 1956 and the Air Force in 1964, the AIM-9 is one of the oldest, cheapest, and most successful air-to-air missiles. Its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13 (AA-2 "Atoll"), a reverse-engineered copy of the AIM-9B, was also widely adopted. Low-level development started in

2967-474: Is a very limited weapon, but it had no serious competitors and counters when it was introduced, causing it to be adopted by the USAF and NATO as a standard weapon, with around 80,000 units being produced from 1958 to 1962. The viewing angle of the AIM-9B's sensor was a minuscule 4 degrees, So at launch, the pilot had to accurately aim the aircraft's sight over or above the target (to account for drag). The speed of

3096-600: Is an optical type using a laser. The warhead uses a directional warhead that can efficiently deliver large attack power. Its overall capabilities are said to exceed that of the American AIM-9L Sidewinder , which the missile was developed off of.

3225-406: Is controlled using a direct-drive electric servo actuator that responds quickly and allows fine-grained control, unlike conventional gas servo systems that use hot gas . In addition, the bank-to-turn technology has been introduced, the seeker and swing angle have been expanded, and two-color infrared rays have been adopted, resulting in a high accuracy rate. The proximity fuse is also made by NEC and

3354-581: Is more accurate and somewhat more resistant to countermeasures. The new rocket motor burns longer and the redesigned body makes the R-13M more maneuverable. K-13M1/R-13M1 : Improved R-13M with new forward fins introduced in 1976. The lackluster performance of the AIM-9B caused the Navy to look for successor. And in 1963 the AAM-N-7 Sidewinder IC was designed, It was developed in two variations:

3483-514: The AIM-95 Agile and SRAAM that were intended to replace it. The Sidewinder is the most widely used air-to-air missile in the West, with more than 110,000 missiles produced for the U.S. and 27 other nations, of which perhaps one percent have been used in combat. It has been built under license by Sweden and other nations. The AIM-9 has an estimated 270 aircraft kills. In 2010, Boeing won

3612-489: The Argentine flag at South Georgia Island , an act that would later be seen as the first offensive action in the war. The Royal Navy ice patrol vessel HMS  Endurance was dispatched from Stanley to South Georgia on the 25th in response. The Argentine military junta, suspecting that the UK would reinforce its South Atlantic Forces, ordered the invasion of the Falkland Islands to be brought forward to 2 April. The UK

3741-580: The Argentine occupation of Southern Thule , secretly sent a force of two frigates and a nuclear-powered submarine , HMS  Dreadnought , to the South Atlantic, codenamed Operation Journeyman . It is unclear whether the Argentines were aware of their presence, but British sources state that they were advised of it through informal channels. Nevertheless, talks with Argentina on Falklands sovereignty and economic cooperation opened in December of that year, though they proved inconclusive. In 1980,

On 31 March 1982, the Argentine ambassador to the UN, Eduardo Roca , began attempting to garner support against a British military build-up designed to thwart earlier UN resolutions calling for both countries to resolve the Falklands dispute through discussion. On 2 April,

4128-636: The Royal Marines . The garrison consisted of 68 marines and eleven naval hydrographers , assisted by 23 volunteers of the Falkland Islands Defence Force (FIDF), who had few weapons and were used as lookouts. The invasion started with the landing of Lieutenant Commander Guillermo Sanchez-Sabarots' Amphibious Commandos Group , who attacked the empty Moody Brook barracks and then moved on Government House in Stanley . When

The conflict began on 2 April 1982, when Argentina invaded and occupied the Falkland Islands , followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched

4386-418: The conical scan was very slow, additionally, the uncooled missile had a low sensitivity and was liable to extraneous heat. The AIM-9B was recommended for use on non-threatening targets (like bombers), only from behind (so it can lock on the thermal radiation from the target engines) and only with the sun behind or to the side of your aircraft (as the missile would lock onto it due to its thermal radiation). It

Due to this, the AAM-3 is expected to be replaced by the AAM-5 . The AAM-3 uses a unique passive dual-wavelength light wave ( infrared and ultraviolet ) homing seeker. The front section is equipped with a large notched canard that improves

4644-426: The 2nd Marine Infantry Battalion with Assault Amphibious Vehicles arrived, the governor ordered a ceasefire and surrendered. The governor, his family and the British military personnel were flown to Argentina that afternoon and later repatriated to the United Kingdom. The British had already taken action prior to the 2 April invasion. In response to events on South Georgia, on 29 March, Ministers decided to send

4773-634: The AAM-3 as a project to replace the existing AIM-9 Sidewinders in Japanese service. The project was rather limited in budget due to the failure of the AAM-2 . The project received a massive boost in development in the 1980s, driven by Japan's needs for more modern military equipment, rocketing the budget to nearly ¥12.2 billion ($ 77.3 million USD). The missile was required to be more capable than existing missiles in Japanese service . The final result came out in

4902-566: The AIM-9. Originally a tail-chasing system, early models saw extensive use during the Vietnam War , but had a low success rate (8% hit rate with the AIM-9E variant). This led to all-aspect capability in the L (Lima) version, which proved an effective weapon during the 1982 Falklands War and Operation Mole Cricket 19 in Lebanon. Its adaptability has kept it in service over newer designs like

5031-561: The AIM-9B, but is worse than the "D". The canard design was changed to a squared tip double delta planform, this helped improve canard behaviour at higher angles of attack (AOA). Over 5,000 AIM-9B's were rebuilt into AIM-9E's. The AIM-9E appeared in Vietnam after the conclusion of the Operation Rolling Thunder in 1968, with the U.S. Air Force (USAF), becoming one of their main missile armaments. Up until Operation Linebacker in 1972 intense air-to-air activity in Vietnam

Admiral Sandy Woodward 's carrier battle group of twelve warships and three supply ships entered the TEZ on 1 May, shortly before the first Black Buck raid, intending to degrade Argentine air and sea forces before the arrival of the amphibious group two weeks later. In anticipation, Admiral Anaya had deployed all his available warships into three task groups. The first

Several of these flights were intercepted by Sea Harriers outside the British-imposed Total Exclusion Zone ; the unarmed 707s were not attacked because diplomatic moves were still in progress and the UK had not yet decided to commit itself to armed force. On 23 April, a Brazilian commercial Douglas DC-10 from VARIG Airlines en route to South Africa

At a private committee meeting that evening, it was reported that Ridley said: "If we don't do something, they will invade. And there is nothing we could do." In the period leading up to the war—and, in particular, following the transfer of power between the military dictators General Jorge Rafael Videla and General Roberto Eduardo Viola late in March 1981—Argentina had been in

This was a significant win for the UK, giving it the upper hand diplomatically. The draft resolution Parsons submitted had avoided any reference to the sovereignty dispute (which might have worked against

5805-589: The Falkland Islands was considered extremely difficult. The chances of a British counter-invasion succeeding were assessed by the US Navy , according to historian Arthur L. Herman , as "a military impossibility". Firstly, the British were significantly constrained by the disparity in deployable air cover. The British had 42 aircraft (28 Sea Harriers and 14 Harrier GR.3s ) available for air combat operations, against approximately 122 serviceable jet fighters, of which about 50 were used as air superiority fighters and

Operation Acme was the deployment of a single Nimrod R.1 surveillance aircraft of No. 51 Squadron RAF to the Chilean base at Isla San Félix to gather signals intelligence from Argentinian forces in the Falklands; three sorties were conducted,

6063-460: The Moody Brook depot were found to have foodstuff missing according to Private Alan Craig from the 7th Regiment, and troops garrisoning Port Howard were starved, and according to Max Hastings and Simon Jenkins in their book The Battle for the Falklands (Norton, 1984), "Attempts to go absent without leave were punished by beatings or forcing the offender to sit for hours with his naked feet in

6192-487: The Navy opted for a different approach after Walt Freitag, a USN engineer proposed a full change to solid-state in one missile. The "H" variant had major changes over the AIM-9D/G, which had multiple issues with reliability. One of the issues was the intolerance of the vacuum tubes to repeated 20ft/sec sink rate landings by US Navy aircraft on carrier decks. The "H" was the first Sidewinder to be fully solid state, replacing

6321-652: The Taiwan strait resulted in a AIM-9B becoming lodged in a MiG-17 without exploding, allowing it to be removed after landing. The Soviets later became aware that the Chinese had at least one Sidewinder, and after some wrangling, were able to persuade the Chinese to send them one of the captured missiles. K-13/R-3 (AA-2) Variants : K-13/R-3 (Object 300) (AA-2 Atoll): It was the standard variant and entered limited service only two years later in 1960.

On 30 April, the British government had brought into force a 200 nautical miles (370 kilometres; 230 miles) Total Exclusion Zone (TEZ) to replace the previous Maritime Exclusion Zone; aircraft as well as ships of any nation were liable to be attacked inside it, if they were aiding

6579-629: The UK ambassador to the UN, Sir Anthony Parsons , that an invasion was imminent and he should call an urgent meeting of the Security Council to get a favourable resolution against Argentina. Parsons had to get nine affirmative votes from the 15 Council members (not a simple majority) and to avoid a blocking vote from any of the other four permanent members. The meeting took place at 11:00   am on 3 April, New York time (4:00   pm in London). United Nations Security Council Resolution 502

The resolution called for the removal only of Argentine forces: this freed Britain to retake the islands militarily, if Argentina did not leave, by exercising its right to self-defence allowed under the UN Charter. The Argentine Army unit earmarked for

Upon detonation, the rods are scattered in a toroidal shape, ensuring that at least some portion of the shrapnel hits enemy aircraft. Newer models of the AIM-9 sought to increase the range that the seeker head's gimbal can turn, allowing

6966-446: The amount of energy devoted to actuating control surfaces, the AIM-9 does not use active roll stabilization. Instead, it uses rollerons , small metal discs protruding out of the aft end of the tips of the tail fins which spin as the missile flies through the air, providing gyroscopic stabilization. The AIM-9 uses a passive infrared proximity fuze to detonate its warhead near an enemy aircraft, scattering shrapnel that aims to damage

7095-636: The cabinet, approval was given to form a task force to retake the islands. This was backed in an emergency sitting of the House of Commons the next day. Word of the invasion first reached the UK from Argentine sources. A Ministry of Defence operative in London had a short telex conversation with Governor Hunt's telex operator, who confirmed that Argentines were on the island and in control. Later that day, BBC journalist Laurie Margolis spoke with an islander at Goose Green via amateur radio , who confirmed

7224-441: The campaign. This was the critical instrument of crisis management for the British with its remit being to "keep under review political and military developments relating to the South Atlantic, and to report as necessary to the Defence and Overseas Policy Committee". The War Cabinet met at least daily until it was dissolved on 12 August. Although Margaret Thatcher is described as dominating the War Cabinet, Lawrence Freedman notes in

7353-425: The capital. Latest Argentine sources confirm that the Vulcan raids did not influence Argentina's decision to move some of its Mirage IIIs from southern Argentina to the Buenos Aires Defence Zone. This dissuasive effect was watered down when British officials made clear that there would not be strikes on air bases in Argentina. The raids were later dismissed as propaganda by Falklands veteran Commander Nigel Ward. Of

7482-502: The designation AIM-9E-2 As the Sidewinder was being acquired by NATO forces, licensed production was given to West Germany and they would produce around 15,000 units. Like the Americans, the West Germans sought to improve the AIM-9B design due to its limitations. The only visible exterior difference is a greenish sensor window, but many tech improvements were added beneath the shell. Unnoticed improvements include solid state electronics (instead of vacuum tubes), carbon dioxide seeker cooling,

7611-408: The early AIM-9A & B was that a non-propulsive attachment (NPA) for their MK 15 motor was provided, assuming an assembled missile would be less dangerous to ground crew and material if the rocket motor was ignited. This same NPA was used in the AIM-9B Sidewinder as well. The AIM-9B is very similar to the AIM-9A, but the "B" has a more sophisticated rear and more aerodynamical front fins. The AIM-9B

The longest and only paved runway was at the capital, Stanley , and even that was too short to support fast jets. Therefore, the Argentines were forced to launch their major strikes from the mainland, severely hampering their efforts at forward staging, combat air patrols , and close air support over

A Dagger and a Canberra were shot down. Combat broke out between Sea Harrier FRS Mk 1 fighters of No. 801 Naval Air Squadron and Mirage III fighters of Grupo 8. Both sides refused to fight at the other's best altitude, until two Mirages finally descended to engage. One

8514-415: The islands continue to operate as a self-governing British Overseas Territory . In 1965, the United Nations called upon Argentina and the United Kingdom to reach a settlement of the sovereignty dispute. The UK Foreign and Commonwealth Office (FCO) regarded the islands as a nuisance and barrier to UK trade in South America. Therefore, while confident of British sovereignty, the FCO was prepared to cede

8643-413: The islands since the early 19th century, are predominantly descendants of British settlers, and strongly favour British sovereignty . Neither state officially declared war , although both governments declared the islands a war zone. The conflict had a strong effect in both countries and has been the subject of various books, articles, films, and songs . Patriotic sentiment ran high in Argentina, but

When news of a proposed transfer broke in 1968, elements sympathetic with the plight of the islanders were able to organise an effective parliamentary lobby to frustrate the FCO plans. Negotiations continued, but in general failed to make meaningful progress; the islanders steadfastly refused to consider Argentine sovereignty on one side, whilst Argentina would not compromise over sovereignty on

Less well known are similar detentions in other outlying settlements, including one islander who died after being denied access to his medication. As the war's end approached, some troops began to place booby traps in civilian homes, defiled homes with excrement, destroyed civilian property and committed arson against civilian properties. Argentine officers and NCOs have been accused of handing out rough Field punishment to their conscript soldiers. Ration packs from

The effective loiter time of incoming Argentine aircraft was low, limiting the ability of fighters to protect attack aircraft, which were often compelled to attack the first target of opportunity, rather than selecting the most lucrative target. The first major Argentine strike force comprised 36 aircraft ( A-4 Skyhawks , IAI Daggers , English Electric Canberras , and Mirage III escorts), and

The conscripts born in 1963 had only recently been called-up, so they were supplemented by the recall of the previous year's intake. Brigadier General Mario Benjamín Menéndez was appointed Military Governor of the Malvinas. Argentine military police arrived with detailed files on many islanders, allowing intelligence officer Major Patricio Dowling to arrest and interrogate islanders who he suspected might lead opposition to

9288-415: The junta's dwindling legitimacy. The newspaper La Prensa speculated on a step-by-step plan beginning with cutting off supplies to the islands, ending in direct actions late in 1982, if the UN talks were fruitless. The ongoing tension between the two countries over the islands increased on 19 March, when a group of Argentine scrap metal merchants (which had been infiltrated by Argentine Marines ) raised

More successful was Operation Fingent, the placement of a Marconi S259 radar on high ground in Tierra del Fuego from where it could monitor movements at southern Argentinian air bases; the RAF crew wore civilian clothes in the guise of a sales team. Information was passed to Northwood and

9546-400: The last sighting. So if the target remained at 5 degrees left between two rotations of the mirror, the electronics would not output any signal to the control system. Consider a missile fired at right angles to its target; if the missile is flying at the same speed as the target, it should "lead" it by 45 degrees, flying to an impact point far in front of where the target was when it was fired. If

9675-533: The late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket . This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile . Due to the Sidewinder's infrared guidance system, the brevity code " Fox two " is used when firing

9804-541: The launcher, which the USAF did not use) ATM-9G (USN) : AIM-9G used for captive flight target acquisition training. Within December 1965, two designers McLean and LaBerge (who were employed by Philco-Ford) came together to create ways to improve the AIM-9G's reliability. One submission was to advance all the remaining missile electronic components from vacuum to solid-state gradually.The US Air Force adhered to this steady replacement of their AIM-9's to solid-state, however

9933-480: The launchers, allowing the missile to track any part of the aircraft heated by air resistance due to high speed flight, giving modern Sidewinders all-aspect capabilities. The nose canards provide maneuverability for the AIM-9, with the AIM-9X using thrust vectoring to augment this. The hot gases generated were used to actuate the nose canards in older models, while newer variants use thermal batteries . To minimize

10062-528: The little-used US Navy AIM-9C Sidewinder. This took longer to develop, and did not enter service until 1966. K-13M/R-13M (Object 380) (AA-2D Atoll) : The R-13M is a much improved version of the R-3S and has capabilities similar to the AIM-9G Sidewinder. The R-13M is still a tail engagement missile only but is far more capable than the R-3S due to its new seeker and rocket motor. The new cooled seeker

10191-501: The mid- Atlantic British overseas territory of Ascension Island . They included a sizeable force of Avro Vulcan B Mk 2 bombers, Handley Page Victor K Mk 2 refuelling aircraft , and McDonnell Douglas Phantom FGR Mk 2 fighters to protect them. Meanwhile, the main British naval task force arrived at Ascension to prepare for active service. A small force had already been sent south to recapture South Georgia. Encounters began in April;

10320-520: The midst of devastating economic stagnation and large-scale civil unrest against the National Reorganization Process , the military junta that had been governing the country since 1976. In December 1981, there was a further change in the Argentine military regime, bringing to office a new junta headed by General Leopoldo Galtieri (acting president), Air Brigadier Basilio Lami Dozo and Admiral Jorge Anaya . Anaya

10449-422: The missile automatically got pre-launch instructions. The conical scanning speed was also increased greatly. The seeker head was now able to seek in a 25˚ circular scan. This allowed the AIM-9G to have an improved chance of acquiring the target than earlier models. This, along with other upgraded solid-state modules, culminated in the AIM-9G. The improvement was substantial enough that an order of 5,000 AIM-9D seekers

10578-506: The missile is traveling four times the speed of the target, it should follow an angle about 11 degrees in front. In either case, the missile should keep that angle all the way to interception, which means that the angle that the target makes against the detector is constant. It was this constant angle that the Sidewinder attempted to maintain. This " proportional pursuit " system is straightforward to implement and offers high-performance lead calculation almost for free and can respond to changes in

10707-458: The missile to track aircraft at greater angles from its direct line of sight, or boresight. Models such as the AIM-9L, AIM-9M, and AIM-9X feature high off-boresight capabilities, meaning they are able to track targets at high seeker gimbal angles, or highly distant from its boresight. The Sidewinder is not guided by the actual position recorded by the detector, but by the change in position since

10836-548: The missile was by Grumman F9F-8 Cougars and FJ-3 Furies of the United States Navy in the middle of 1956. Nearly 100,000 of the first generation (AIM-9B/C/D/E) of the Sidewinder were produced with Raytheon and General Electric as major subcontractors. Philco-Ford produced the guidance and control sections of the early missiles. The NATO version of the first-generation missile was built under license in Germany by Bodenseewerk Gerätetechnik ; 9,200 examples were built. AIM-9A

10965-467: The missile's manoeuvrability, and has a stabilizing wing at the end. Developed by NEC , the seeker is very resistant to aircraft-deployed countermeasures due to its Noise Removal technology. In addition, the swing angle of the seeker is large, so the dome at the tip of the missile is larger than that of the AIM-9 Sidewinder. The missile also has high off- boresight capability, and the missile

11094-645: The news to the media, telling them to "Just rejoice at that news, and congratulate our forces and the Marines!" On 1 May, British operations on the Falklands opened with the "Black Buck 1" attack (of a series of five) on the airfield at Stanley. A Vulcan bomber from Ascension flew an 8,000-nautical-mile (15,000 km; 9,200 mi) round trip, dropping conventional bombs across the runway at Stanley. The mission required repeated aerial refuelling using several Victor K2 tanker aircraft operating in concert, including tanker-to-tanker refuelling. The overall effect of

11223-516: The night of the invasion, a banquet was held at Roca's official residence for the US ambassador to the UN, Jeane Kirkpatrick , and several high-ranking officials of the United States Department of State and the United States Department of Defense . This led British diplomats to view Kirkpatrick, who had earlier called for closer relationships with South American dictatorships, with considerable suspicion. On 1 April, London told

11352-556: The night, and Mirage IIIs (without air refuelling capability or any capable AAM) as decoys to lure away the British Sea Harriers. The decoying would be later extended with the formation of the Escuadrón Fénix , a squadron of civilian jets flying 24 hours a day, simulating strike aircraft preparing to attack the fleet. On one of these flights on 7 June, an Air Force Learjet 35 A was shot down by HMS Exeter, killing

11481-420: The occupation was the 25th Infantry Regiment , a unit of about 681 men specially trained from all the regions of Argentina ; it was flown into Port Stanley Airport as soon as the runway had been cleared. Once it became clear that the British were sending an amphibious task force, there was a general recall of reservists and two brigades of eight infantry regiments and their supporting units were dispatched to

11610-639: The occupation. Initially, Islanders suspected of holding anti-Argentine views were expelled, including the Luxton family (who had lived in the islands since the 1840s) and David Colville, editor of the Falklands Times . This proved to be counter-productive, as those expelled gave interviews to the press. Subsequently, fourteen other community leaders, including the senior medical officer, were interned at Fox Bay on West Falkland. Concerned by Dowling's actions, senior Argentine officers had him removed from

11739-416: The ocean liner SS  Canberra was requisitioned and set sail two days later with the 3 Commando Brigade aboard. The ocean liner Queen Elizabeth 2 was also requisitioned, and left Southampton on 12 May, with the 5th Infantry Brigade on board. The whole task force eventually comprised 127 ships: 43 Royal Navy vessels, 22 Royal Fleet Auxiliary ships, and 62 merchant ships . The retaking of

11868-458: The original vacuum tubes. The AIM-9H also included a new lead sulphide detector, using nitrogen cooling. The new guidance package was built using semiconductors. When the engineers redesigned these electronics, they essentially kept the AIM-9G's optical system, but the tracking rate increased further, from the original 12˚ to 20˚ degrees per second, this complementing the more powerful 120 lb.ft actuators that had been installed. They also replaced

11997-454: The other 7 were MiG-21s. This was due to the missile design and USN fighter pilot training at TOPGUN . The United States Air Force attempted to attain AIM-9Gs from the USN, due to bad experience with their AIM-9 Sidewinders models (B, E, and J), but they were incompatible with US Air Force's Sidewinder launchers due to the different cooling mechanisms. (the USN used a nitrogen gas container on

12126-404: The other. The FCO then sought to make the islands dependent on Argentina, hoping this would make the islanders more amenable to Argentine sovereignty. A Communications Agreement signed in 1971 created an airlink and later YPF, the Argentine oil company, was given a monopoly in the islands. In 1977, the British prime minister, James Callaghan , in response to heightened tensions in the region and

12255-557: The presence of a large Argentine fleet and that Argentine forces had taken control of the island. British military operations in the Falklands War were given the codename Operation Corporate , and the commander of the task force was Admiral Sir John Fieldhouse . Operations lasted from 1 April 1982 to 20 June 1982. On 6 April, the British Government set up a War Cabinet to provide day-to-day political oversight of

12384-509: The raids on the war is difficult to determine. The runway was cratered by only one of the twenty one bombs, but as a result, the Argentines realised that their mainland was vulnerable and fighter aircraft were redeployed from the theatre to bases further north. Historian Lawrence Freedman , who was given access to official sources, comments that the significance of the Vulcan raids remains a subject of controversy. Although they took pressure off

12513-547: The remainder as strike aircraft , in Argentina's air forces during the war . Crucially, the British lacked airborne early warning and control (AEW) aircraft. Planning also considered the Argentine surface fleet and the threat posed by Exocet -equipped vessels or the two Type 209 submarines . By mid-April, the Royal Air Force had set up an airbase on RAF Ascension Island , co-located with Wideawake Airfield, on

12642-629: The ship, died in the incident. More than 700 men were eventually rescued from the open ocean despite cold seas and stormy weather, enduring up to 30 hours in overcrowded life rafts. The loss of General Belgrano drew heavy criticism from Latin American countries and from opponents of the war in Britain; support for the British cause wavered amongst some European allies, but the United States remained supportive. Regardless of controversies over

12771-418: The sinking — including disagreement about the exact nature of the exclusion zone and whether General Belgrano had been returning to port at the time of the sinking — it had a crucial strategic effect: the elimination of the Argentine naval threat. After her loss, the entire Argentine fleet, with the exception of the diesel-powered submarine ARA  San Luis , returned to port and did not leave again during

12900-413: The slewing of the optics through a search pattern to acquire the enemy (most likely using a rosette scan ), it also allowed the slaving of the optics to a radar or helmet sight. This was connected to the onboard computer of the aircraft, which gave the capability of capturing the target using the data coming from the airborne radar. This meant that the target could be locked without being in the sights, and

13029-549: The small Sea Harrier force, the raids were costly and used a great deal of resources. The single hit to the edge of the runway was probably the best that could have been expected. Contrary to some reports, this reduced the capability of the runway to operate Mirage III fast jets but not other, smaller jet fighters, the Pucara , and the Hercules C-130 . Nor did it cause the Argentine air force to deploy Mirage IIIs to defend

13158-466: The squadron commander, Vice Commodore Rodolfo de la Colina, the highest-ranking Argentine officer to die in the war. Stanley was used as an Argentine strongpoint throughout the conflict. Despite the Black Buck and Harrier raids on Stanley airfield (no fast jets were stationed there for air defence) and overnight shelling by detached ships, it was never out of action entirely. Stanley was defended by

13287-494: The submarine HMS  Superb left Gibraltar and it was assumed in the press she was heading south. There has since been speculation that the effect of those reports was to panic the Argentine junta into invading the Falklands before submarines could be deployed; however, post-war research has established that the final decision to proceed was made at a junta meeting in Buenos Aires on 23 March. The following day, during

13416-419: The submarine, scoring hits. Santa Fe was damaged badly enough to prevent her from diving. The crew abandoned the submarine at the jetty at King Edward Point on South Georgia. With Tidespring now far out to sea and the Argentine forces augmented by the submarine's crew, Major Sheridan decided to gather the 76 men he had and make a direct assault that day. After a short forced march by the British troops and

13545-476: The target's flight path, which is much more efficient and makes the missile "lead" the target. During World War II , various researchers in Germany designed infrared guidance systems of various complexity. The most mature development of these, codenamed Hamburg , was intended for use by the Blohm & Voss BV 143 glide bomb in an anti-ship role. Hamburg used a single IR photocell as its detector along with

13674-618: The thermal battery with a turbo-alternator. The AIM-9H also included a continuous-rod bundle warhead, improving its destructive capability. The AIM-9H was the last and most manoeuvrable of the rear-aspect USN Sidewinders, with USN moving to the all-aspect AIM-9L. The AIM-9H was actually used at the very end of the Vietnam war, with it being introduced into the US navy service in 1972 and being used in Operation Linebacker . A total of around 7,700 AIM-9H units would be manufactured from 1972-1974 by Philco-Ford and Raytheon. The AIM-9H

13803-459: The time the war ended. In the immediate post-war era, Allied military intelligence teams collected this information, along with many of the engineers working on these projects. Several lengthy reports on the various systems were produced and disseminated among the Western aircraft firms, while a number of the engineers joined these companies to work on various missile projects. By the late 1940s

13932-542: The unfavourable outcome prompted large protests against the ruling military government , hastening its downfall and the democratisation of the country . In the United Kingdom, the Conservative government, bolstered by the successful outcome, was re-elected with an increased majority the following year . The cultural and political effect of the conflict has been less in the UK than in Argentina, where it has remained

14061-604: The wounded up until the end of the conflict. The only Argentine Hercules shot down by the British was lost on 1 June when TC-63 was intercepted by a Sea Harrier in daylight as it was searching for the British fleet north-east of the islands, after the Argentine Navy retired its last SP-2H Neptune due to unreliability. Various options to attack the home base of the five Argentine Étendards at Río Grande were examined and discounted ( Operation Mikado ); subsequently five Royal Navy submarines were lined up, submerged, on

14190-422: Was a major episode in the protracted dispute over the territories' sovereignty . Argentina asserted (and maintains) that the islands are Argentine territory, and the Argentine government thus described its military action as the reclamation of its own territory. The British government regarded the action as an invasion of a territory that had been a Crown colony since 1841. Falkland Islanders, who have inhabited

14319-560: Was a pre-production of the Sidewinder, first fired successfully in September 1953. Missile production began in 1955, and the first models entered the Navy's fleet service in 1956. Generally, it was a prototype production run, with 240 pieces being produced, and mainly intended for training pilots in air combat techniques. The AIM-9A was initially called the AAM-N-7 before the tri-service designation change in 1962. An interesting fact about

14448-453: Was added for the fuze, being the first in the world. This enhanced the missile's head sensitivity. Maneuverability was also improved with a faster tracking rate, as well as a new actuator system. The Sidewinder's range was improved as well, with the new Hercules MK 36 solid-fuel rocket motor allowing the missile to fly up to 18km. Finally, a new Mk 48 continuous-rod warhead was fitted to the missile for increased damage; this also meant infrared or

14577-534: Was adopted by 10 to 1 (with Panama voting against) and 4 abstentions. Significantly, the Soviet Union and China both abstained. The resolution stated: Deeply disturbed at reports of an invasion on 2 April 1982 by armed forces of Argentina; Determining that there exists a breach of the peace in the region of the Falkland Islands (Islas Malvinas), Demands an immediate cessation of hostilities; Demands an immediate withdrawal of all Argentine forces from

14706-713: Was aware of the Argentine carrier group approaching from the other direction and ordered the cruiser to be attacked to avoid being caught in a pincer movement ; he was unaware that the Veinticinco de Mayo had failed to gain enough headwind to launch her aircraft. The order to sink the cruiser was confirmed by the War Cabinet in London and the General Belgrano was hit by two torpedoes at 4 pm local time on 2 May, sinking an hour later. 321 members of General Belgrano ' s crew, along with two civilians on board

14835-473: Was cancelled at the last minute. On 30 April, the Reagan administration announced that they would be publicly supporting the United Kingdom. The nuclear-powered submarine Conqueror set sail from Faslane, Scotland on 4 April. The two aircraft carriers Invincible and Hermes and their escort vessels left Portsmouth , England only a day later. On its return to Southampton from a world cruise on 7 April,

14964-491: Was centred around the aircraft carrier ARA  Veinticinco de Mayo with two old but missile-armed destroyers, and a second comprised three modern frigates. Both these groups were intended to approach the TEZ from the north. A third group approaching from the south was led by the Second World War -vintage Argentine light cruiser ARA  General Belgrano ; although old, her large guns and heavy armour made her

15093-432: Was famously the first Sidewinder variant to be fired in anger as on 24 September 1958, it achieved the world's first successful kill with a air-to-air missiles, when Taiwanese F-86Fs shot down Communist Chinese MiG-15s using AIM-9Bs supplied and fitted by the U.S. Navy (USN). RB24 : A Swedish AIM-9B Sidewinder. K-13/R-3 (AA-2) : The K-13/R-3 was a reversed engineered AIM-9B Sidewinder, A engagement on 28 September 1958 in

15222-589: Was initially taken by surprise by the Argentine attack on the South Atlantic islands, despite repeated warnings by Royal Navy captain Nicholas Barker (Commanding Officer of the Endurance ) and others. Barker believed that Defence Secretary John Nott 's 1981 Defence White Paper (in which Nott described plans to withdraw the Endurance , the UK's only naval presence in the South Atlantic) had sent

15351-540: Was intercepted by British Harriers who visually identified the civilian plane. The South Georgia force, Operation Paraquet , under the command of Major Guy Sheridan RM, consisted of Marines from 42 Commando , a troop of the Special Air Service (SAS) and Special Boat Service (SBS) troops who were intended to land as reconnaissance forces for an invasion by the Royal Marines, a total of 240 men. All were embarked on RFA  Tidespring . First to arrive

15480-550: Was not present. There were 71 AIM-9E launch attempts from January to October 1972, however, only 6 missiles managed to down an aircraft, with 1 other hitting an aircraft, but not causing complete destruction. Reasons for the poor success rate was listed as "poor air crew training, launches out of the envelope, the tactical situation, marginal tone, tone discrimination, the missile going ballistic, and other malfunctions". AIM-9E : Standard production model. AIM-9E-2 : Some "E" models are equipped with reduced-smoke rocket motors and have

15609-456: Was sent on 1 May, in the belief that the British invasion was imminent or landings had already taken place. Only a section of Grupo 6 (flying IAI Dagger aircraft) found ships, which were firing at Argentine defences near the islands. The Daggers managed to attack the ships and return safely. This greatly boosted the morale of the Argentine pilots, who now knew they could survive an attack against modern warships, protected by radar ground clutter from

15738-414: Was shot down by an AIM-9L Sidewinder air-to-air missile (AAM), while the other escaped but was damaged and without enough fuel to return to its mainland airbase. The plane made for Stanley, where it fell victim to friendly fire from the Argentine defenders. As a result of this experience, Argentine Air Force staff decided to employ A-4 Skyhawks and Daggers only as strike units, the Canberras only during

15867-526: Was stopped at 1,850 units, with the rest being ordered to AIM-9G seeker specifications instead. Around 2120 AIM-9G were built by Raytheon from 1970 to 1972. The AIM-9G would be used with its predecessor, the AIM-9D, during the Vietnam War, as the US Navy's choice of IR missile. A 46% hit rate with the AIM-9G during Operation Linebackers I and II in 1972 was achieved, of which 14 aircraft were MiG-17s and

15996-597: Was the Churchill -class submarine HMS Conqueror on 19 April, and the island was over-flown by a Handley Page Victor aircraft with radar-mapping equipment on 20 April, to establish that no Argentine ships were in the vicinity. The first landings of SAS and SBS troops took place on 21 April, but an ill-advised mission to establish an SAS observation post on the Fortuna Glacier had to be withdrawn after two helicopters crashed in fog and high winds. On 23 April,

16125-492: Was the basis for the all-aspect USAF/USN AIM-9L. ATM-9H : Was a training version of the AIM-9H for captive flight target acquisition. The AIM-9K was a planned U.S. Navy (USN) upgrade to the AIM-9H, but the development was abandoned in favour of USAF/USN joint AIM-9L. Falklands War Operation Corporate The Falklands War (Spanish: Guerra de Malvinas ) was a ten-week undeclared war between Argentina and

16254-491: Was the first version developed solely by the U.S. Air Force (USAF). The AIM-9E allows the expansion of the weapons acquisition envelope, especially at low-altitude, increasing its Probability of Kill (P[k]). It achieved this using a new low-drag conical nose head, being a distinguishing feature of USAF Sidewinders. A magnesium fluoride seeker dome was introduced, along with a more compact optical assembly, an improved guidance control system, new electronics, and significant changes to

16383-441: Was the first version to enter widespread production, in spite of a very long seeker settling time around 22 seconds, as opposed to 11 seconds for the original version. PL-2 : Chinese produced R-3S. A-91 : Romanian produced R-3S. K-13R/R-3R (Object 320) (AA-2B/C Atoll) : While the R-3S was being introduced in 1961, work started on a semi-active radar homing (SARH) version for high-altitude use, with 8 km range, similar to

16512-512: Was the main architect and supporter of a military solution for the long-standing claim over the islands, expecting that the United Kingdom would never respond militarily. By opting for military action, the Galtieri government hoped to mobilise the long-standing patriotic feelings of Argentines towards the islands, diverting public attention from the chronic economic problems and the ongoing human rights violations of its Dirty War , bolstering

16641-428: Was the only planned modification. Recognizing the limitations of the initial AIM-9B, the US Navy (USN) worked to improve the missile's performance. They changed the missile nose to an aerodynamical ogival nose. The seeker was improved with a wider field of view beyond 25 degrees and a reduced instantaneous field of view of 2.5 degrees, to reduce foreign thermal interference (from flares). A better nitrogen cooling system
