135-708: The Arleigh Burke class of guided-missile destroyers (DDGs) is a United States Navy class of destroyer centered around the Aegis Combat System and the SPY-1D multi-function passive electronically scanned array radar . The class is named for Admiral Arleigh Burke , an American destroyer officer in World War II and later Chief of Naval Operations . With an overall length of 505 to 509.5 feet (153.9 to 155.3 m), displacement ranging from 8,300 to 9,700 tons, and weaponry including over 90 missiles,

270-515: 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 After hearing from Thatcher that the task force would not be withdrawn unless the Argentines evacuated their troops, Haig headed for Buenos Aires.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

405-580: A $ 170.7 million letter contract for USS  John Finn  (DDG-113) long lead-time materials. Shipbuilding contracts for DDG 113 to DDG 115 were awarded in mid-2011 for $ 679.6 million–$ 783.6 million; these do not include government-furnished equipment such as weapons and sensors, which took the average cost of the FY2011/12 ships to about $ 1.843 billion per vessel. DDG 113-115 are "restart" ships, similar to previous Flight IIA ships, but including modernization features such as OACE and

540-409: A SeaRAM. In February 2018, Lockheed Martin received a contract to deliver its High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS) system for installation onto an Arleigh Burke destroyer. HELIOS is a "60+ kW"-class laser, scalable to 120 kW, that can "dazzle" or destroy small boats and UAVs up to 8.0 km (5 mi) away. It would be the first laser weapon put on

675-635: 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,

810-482: A contract to modernize 11 ships. In May 2014, USNI News reported that 21 of the 28 Flight I and II Arleigh Burke -class destroyers would not receive the full mid-life upgrade that included electronics and Aegis Baseline 9 software for SM-6 compatibility; instead, they would retain the basic BMD 3.6.1 software in a $ 170 million upgrade concentrating on HM&E systems, and on some ships, their anti-submarine suite. Seven Flight I ships—DDGs 51–53, 57, 61, 65, 69—received

945-603: 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

1080-464: 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

1215-780: 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

1350-531: 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

1485-467: 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

1620-814: A secondary anti-ship role. The SM-2 uses semi-active radar homing (SARH); up to three targets may be simultaneously intercepted as the Arleigh Burke s have three AN/SPG-62 fire-control radars for terminal target illumination. The SM-6, which provides over-the-horizon defense, and the SM-2 Block IIIC feature a dual-mode seeker with active radar homing (ARH) capability; they do not have to rely on external illumination, so more targets may be intercepted simultaneously. Flights IIA and III—and modernized Flight I and II ships—can carry RIM-162 Evolved SeaSparrow Missiles (ESSMs), which provide medium-range air defense and are also capable of targeting other ships. ESSM

1755-644: 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

1890-612: A service life extension to justify refit costs that would only prolong their service lives a short time when they are already more expensive to operate, and the newest Flight III ships that are optimized for BMD would be given a new, complex mission requiring a major refit shortly after introduction. About 20 Flight IIA destroyers will undergo further modernization under the DDG MOD 2.0 program. DDG MOD 2.0 will backfit SPY-6(V)4 and Aegis Baseline 10 to provide similar capabilities to Flight III ships, as well as upgrade cooling systems to support

2025-526: 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

2160-429: A steel hull with a superstructure made of lighter aluminum to reduce top weight, but the lighter metal proved vulnerable to cracking. Aluminum is also less fire-resistant than steel; a 1975 fire aboard USS  Belknap gutted her aluminum superstructure. Battle damage to Royal Navy ships exacerbated by their aluminum superstructures during the 1982 Falklands War supported the decision to use steel. Other lessons from

2295-416: 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

2430-524: A total of four or eight Harpoons, providing an anti-ship capability with a range in excess of 65 nautical miles (120 km; 75 mi). During Exercise RIMPAC 2024, DDG-62 , a Flight I ship, launched a Naval Strike Missile (NSM); the launchers for the Harpoons were removed to make room for the NSM's proprietary launch boxes. The class can perform tactical land strikes with VLS-launched Tomahawks . With

2565-685: A warship. In November 2019, USS  Dewey  (DDG-105) had the Optical Dazzling Interdictor, Navy (ODIN) system installed. ODIN differs from the XN-1 LaWS previously mounted on USS  Ponce in that ODIN functions as a dazzler, which blinds or destroys optical sensors on drones rather than shooting down the aircraft. HELIOS was delivered to the Navy in August 2022 and installed on USS  Preble  (DDG-88) . Preble

2700-815: Is done in two phases: the first phase updates the hull, mechanical, and electrical (HM&E) systems, while the second phase focuses on Aegis Combat System upgrades and introduces an Open Architecture Computing Environment (OACE). By 2017, modernization technologies were introduced to production ships, and the Navy started modernization of Flight IIA ships through a single process combining both phases of upgrading. The capabilities of modernized destroyers include CEC, Integrated Air and Missile Defense (IAMD), ESSM support, improved electronic support with Surface Electronic Warfare Improvement Program (SEWIP) Block 2, improved data processing with Boeing 's Gigabit Ethernet Data Multiplex System, and improvements to littoral warfare . In July 2010, BAE Systems announced it had been awarded

2835-502: Is small enough to be quad-packed into a single Mk 41 VLS cell. ESSM Block 1 uses SARH, guided similarly to older SM-2s. ESSM Block 2, which achieved initial operating capability (IOC) in 2021, features a dual-mode seeker with ARH capability. The SM-3 , SM-6, and SM-2ER Block IV provide Ballistic Missile Defense (BMD), the SM-3 being an exoatmospheric interceptor and the latter two having terminal phase anti-ballistic capability. So vital has

2970-607: The AN/SPQ-9B , a feature of Flight III, instead of the AN/SPS-67. Flight III proper began with the third ship procured in 2016, USS  Jack H. Lucas (DDG-125). In place of the canceled CG(X) program, the U.S. Navy began detailed design work on a DDG 51 Flight III design in FY2013. The Navy planned to procure 24 Flight III ships from FY2016 to FY2031. In June 2013, it awarded $ 6.2 billion in destroyer contracts. Costs for

3105-597: The AN/SPY-1 D passive electronically scanned array (or the AN/SPY-6 active electronically scanned array on Flight III ships), which allows continual tracking of targets simultaneous to area scans. The system's computer control also allows centralization of the previously separate tracking and targeting functions. The system is resistant to electronic countermeasures . The Standard Missile SM-2MR / ER and SM-6 provide area air defense, though they may also be used in

3240-684: The AN/SQQ-89 ASW combat system, which is integrated with Aegis. It encompasses the AN/SQS-53C bow-mounted sonar and a towed array sonar, though several Flight IIA ships do not have a towed array. The towed array is either the AN/SQR-19 Tactical Towed Array Sonar (TACTAS) or the newer TB-37U Multi-Function Towed Array (MFTA). The ships can carry standoff RUM-139 vertical launch anti-submarine rockets . A Mark 32 triple torpedo tubes mount on each side of

3375-672: The AN/WLD-1 Remote Minehunting System (RMS). However, only Pinckney , Momsen , and Bainbridge were installed with the system before the RMS program was canceled. Efforts to modernize the Arleigh Burke class began amid congressional concerns over the retirement of the Iowa -class battleship . In 1996, the Navy began a program to field the Extended Range Guided Munition (ERGM) for

3510-509: The Aegis BMD role become that all ships of the class are being updated with BMD capability. By January 2023, there were 51 BMD-capable Arleigh Burke -class destroyers. Flight III ships have been delivered since 2023 with AN/SPY-6(V)1 radars and improved BMD capabilities; Flight IIA ships are also planned to receive these upgrades with AN/SPY-6(V)4 radar retrofits. Flights I and II carry two stand-alone Harpoon anti-ship missile launchers for

3645-543: The Aegis Ballistic Missile Defense System , as well as the introduction of the AN/SPY-6 radar system, the class has also evolved capability as mobile anti-ballistic missile and anti-satellite platforms. The lead ship of the class, USS  Arleigh Burke , was commissioned during Admiral Burke's lifetime on 4 July 1991. With the decommissioning of the last Spruance -class destroyer, USS  Cushing , on 21 September 2005,

3780-489: 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

3915-580: 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,

4050-579: The Arleigh Burke -class destroyers are larger and more heavily armed than many previous classes of guided-missile cruisers . These warships are multi-mission destroyers able to conduct anti-aircraft warfare with Aegis and surface-to-air missiles ; tactical land strikes with Tomahawk missiles ; anti-submarine warfare (ASW) with towed array sonar , anti-submarine rockets , and ASW helicopters ; and anti-surface warfare (ASuW) with ship-to-ship missiles and guns. With upgrades to their AN/SPY-1 radar systems and their associated missile payloads as part of

4185-564: The Arleigh Burke -class ships became the U.S. Navy's only active destroyers until the Zumwalt class became active in 2016. The Arleigh Burke class has the longest production run of any U.S. Navy surface combatant . As of October 2023, all seventy-three built are active, with nineteen more planned to enter service. The Arleigh Burke -class destroyer has four variants, referred to as "Flights". Newer Flights incorporate technological advancements. The Arleigh Burke -class ships are among

4320-441: The Arleigh Burke s are more heavily armed than many preceding guided-missile cruiser classes. The Arleigh Burke -class destroyer is equipped with the Aegis Combat System , which combines information from the ship's sensors to display a coherent image of the environment and guides weapons to targets using advanced tracking and fire control. Their main radar differs from traditional mechanically rotating radars. Instead, Aegis uses

4455-593: The Conventional Prompt Strike program. However, the C-HGB is expected to be around 3 ft (0.91 m) wide, making it too large to fit in Mk 41 VLS tubes or on deck launchers. Installing them on Arleigh Burke destroyers would require removing some Mk 41 cells to accommodate the larger weapon, an expensive and time-consuming process. There is criticism of this idea: the oldest Flight I ships would need

4590-636: The Official History of the Falklands Campaign that she did not ignore opposition or fail to consult others. However, once a decision was reached, she "did not look back". 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,

4725-419: The Optical Dazzling Interdictor, Navy (ODIN), a directed energy weapon that can target unmanned vehicles. DDG 88 is equipped with the higher-power High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS). Flights IIA and III have two hangars for stowing MH-60 helicopters. Their Light Airborne Multi-Purpose System (LAMPS) helicopter system improves the ship's capabilities by enabling

4860-513: The Royal Fleet Auxiliary (RFA) Fort Austin south from the Mediterranean to support HMS Endurance , and the nuclear-powered fleet submarine HMS  Spartan from Gibraltar , with HMS  Splendid ordered south from Scotland the following day. Lord Carrington had wished to send a third submarine, but the decision was deferred due to concerns about the impact on operational commitments. Coincidentally, on 26 March,

4995-636: 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

5130-638: The U.S. 6th Fleet based in Naval Station Rota, Spain (USS Carney , USS Ross , USS Donald Cook , and USS Porter ) received self-protection upgrades, replacing one of their two Phalanx CIWS with a SeaRAM CIWS, which combines the Phalanx sensor dome with an 11-cell RIM-116 launcher. This was the first time the system was paired with an Aegis ship. Another four ships (USS Arleigh Burke , USS Roosevelt , USS Bulkeley , and USS Paul Ignatius ) have since been forward-deployed to Rota and also received

5265-576: The 11-cell SeaRAM. It is unclear if ships with two Phalanx CIWS or ships already in a Phalanx-SeaRAM configuration will retain one Phalanx. USS  Michael Murphy  (DDG-112) was originally intended to be the last of the Arleigh Burke class. The Navy planned to shift production to the Zumwalt -class destroyer focusing on NGFS and littoral operations. However, at a July 2008 hearing, Navy officials announced intentions to restart Arleigh Burke production in place of additional Zumwalt s, testifying to

5400-426: 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

5535-493: The 30 mm Mk44 Bushmaster II instead of the 25 mm M242 Bushmaster of previous variants. The Mk 38 Mod 4 is planned to be fielded on Flight IIA and III Arleigh Burke -class destroyers. In October 2020, National Security Advisor Robert C. O'Brien said that all three Flights of the Arleigh Burke -class destroyer would field the Common-Hypersonic Glide Body (C-HGB) missile developed under

5670-558: The AN/SPS-73(V)12. Subsequent Flight IIA ships employ additional signature-reduction measures: the hangars of DDG 86 onwards are made of composite materials , and the exhaust funnels of DDG 89 onwards are shrouded by the superstructure. The use of the improved SPY-1D(V) radar, starting with USS  Pinckney  (DDG-91) , enhances the ships' ability to filter out clutter and resist electronic attack. Several Flight IIA ships were constructed without any Phalanx CIWS because of

5805-448: The Argentine occupation. 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

The Lynx launched a torpedo , and strafed the submarine with its pintle -mounted general purpose machine gun ; the Wessex also fired on Santa Fe with its GPMG . The Wasp from HMS  Plymouth as well as two other Wasps launched from HMS  Endurance fired AS-12 ASM antiship missiles at

6075-712: The British Task Force was shadowed by Boeing 707 aircraft of the Argentine Air Force during their travel to the south. 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

6210-573: The British had sought a long-term lease of 99 years, whereas Argentina was pressing for a much shorter period of only thirty years.) 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

6345-794: The DDG 51 class. The ERGM was to extend the class's 5-inch Mark 45 gun range to 63 nautical miles (117 km). It necessitated a modification of the gun; the 62-caliber Mark 45 Mod 4 was created and installed on DDG 81 and onwards in anticipation of the ERGM. However, the ERGM was canceled in 2008. The current DDG 51 modernization program is designed to provide mid-life upgrades to ensure the destroyers remain effective with service lives of at least 35 years. Modernization of existing ships provides commonality with in-production ships. The program's goals are reduced manning, increased mission effectiveness, and reduced total cost. Mid-life modernization of Flight I and II ships

6480-625: The Falkland Islands (Islas Malvinas); Calls on the Governments of Argentina and the United Kingdom to seek a diplomatic solution to their differences and to respect fully the purposes and principles of the Charter of the United Nations. 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

6615-589: 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

6750-717: The Falklands War led to the Navy's decision to protect the Arleigh Burke class's vital spaces with double-spaced steel layers, which create a buffer against anti-ship missiles (AShMs), and Kevlar spall liners. Arleigh Burke destroyers are equipped with AN/SLQ-32 electronic warfare (EW) suites that provide electronic support . Vessels with the SLQ-32(V)3, SLQ-32(V)6, or SLQ-32(V)7 variant can jam radars. The destroyers have Mark 36 infrared and chaff decoy launchers, as well as Nulka decoy launchers, for spoofing incoming AShMs. For defeating incoming torpedoes,

7560-503: The Navy proposed a procurement plan for nine ships, with an option for a tenth, to build two ships a year from 2023 to 2027. Some lawmakers pushed to add a third ship to be built in 2023, bringing the total of the proposed deal to eleven ships. This would follow the Navy's two-ship per year procurement from 2018 to 2022. DDG-116 to DDG-124 and DDG-127 will be "Technology Insertion" ships with elements of Flight III. For example, USS  Delbert D. Black  (DDG-119) and onwards have

7695-607: The SM-2ER Block IV. An expansion of fuel capacity slightly increased the displacement. The Flight IIA design was first procured in FY1994. Among the additions are two hangars and support facilities for ASW helicopters, Cooperative Engagement Capability (CEC), the Kingfisher mine detection system, and five blast-resistant bulkheads . To accommodate the hangars, the length was increased to 509.5 ft (155.3 m), and

7830-483: The SPY-6(V)4, Aegis Baseline 10, and cooling system upgrades during a later depot modernization period. Starting in 2025, the Navy will replace Phalanx CIWS on the destroyers with RIM-116 Rolling Airframe Missile (RAM) launchers to improve their point defense capability. Arleigh Burke s with the latest Aegis baselines will receive the 21-cell Mk 49 RAM launcher; Arleigh Burke s with older Aegis software will receive

7965-588: The TB-37U MFTA, which are being backfit onto previous ships. The U.S. Navy was considering extending the acquisition of Arleigh Burke -class destroyers into the 2040s, according to revised procurement tables sent to Congress, with the procurement of Flight IV ships from 2032 through 2041. This was canceled to cover the cost of the Columbia -class submarines , with the air defense commander role retained on one cruiser per carrier strike group . In April 2022,

Zumwalt's approach to the fleet was a "high-low mix"—a few high-end, high-cost warships supplemented by numerous low-end, low-cost warships. The introduction of the Aegis-equipped Ticonderoga -class cruiser in the early 1980s filled the high end. The Navy started work to develop a lower-cost Aegis-equipped vessel to fill the low end and replace

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

9315-425: 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

9450-562: The class has two AN/SLQ-25 Nixie towed countermeasures. The ships' Prairie-Maskers can reduce their radiated noise. A collective protection system makes the Arleigh Burke class the first U.S. warships designed with an air-filtration system against nuclear, biological, and chemical warfare (NBC). Other NBC defenses include double air-locked hatches, pressurized compartments, and an external countermeasure washdown system. The class's electronics are hardened against electromagnetic pulses . Fire suppression equipment includes water sprinklers in

9585-406: The class was introduced in FY1992. The incorporation of the AN/SRS-1A(V) Combat Direction Finding enhanced detection of signals. The TADIX-B , JTIDS Command and Control Processor, and Link 16 improved communication with other assets. The SLQ-32 EW suite was upgraded to (V)3, and the SPS-67 (V)3 surface search radar was upgraded to (V)5. Flight II also gained the capability to launch and control

9720-470: The contract to be the lead ship design agent. The Navy contracted Ingalls Shipbuilding to build the second ship. Political restraints led to design restrictions, including the absence of helicopter hangars, a displacement limit of 8,300 tons, and a 50-foot shorter hull than the Ticonderoga 's. The designers were forced to make compromises, such as a wide flaring bow. To compensate for the limited length,

9855-509: The design would be "at best marginally effective" because of the "now-shrunken radar". The U.S. Navy disagreed with the GAO findings, stating that the DDG 51 hull was "absolutely" capable of fitting a large enough radar to meet requirements. Guided-missile destroyer Guided-missile destroyers are equipped with large missile magazines, with modern examples typically having vertical-launch cells . Some contain integrated weapons systems, such as

9990-678: The development of the Tomahawk Block V, all existing Block IV Tomahawks carried will be converted to the Block V. The Tomahawk Block Va version is called the Maritime Strike version, and it provides anti-ship capability in addition to its land attack role. The Block Vb version features the Joint Multi-Effects Warhead System for hitting a wider variety of land targets. Arleigh Burke -class ships have

10125-482: The edge of Argentina's 12-nautical-mile (22 km; 14 mi) territorial limit to provide early warning of bombing raids on the British task force. Operation Folklore was a plan to deploy two Canberra PR.9 aircraft of No. 39 Squadron RAF , disguised in Chilean Air Force markings, to the Chilean air base at Punta Arenas , with the intention of undertaking high-level photo-reconnaissance flights over

10260-409: The fighting. This had the secondary effect of allowing the British to redeploy their nuclear submarines to the coast of Argentina, where they were able to provide early warning of outgoing air attacks leaving mainland bases. However, settling the controversy in 2003, the ship's captain, Hector Bonzo, stated to a documentary crew that General Belgrano had actually been manoeuvring, not sailing away from

10395-533: The first ship was $ 1.1 billion, the other $ 778 million being for the ship's weapons systems. USS Arleigh Burke was laid down by the Bath Iron Works at Bath, Maine , on 6 December 1988, and launched on 16 September 1989 by Mrs. Arleigh Burke. The Admiral himself was present at her commissioning ceremony on 4 July 1991, held on the waterfront in downtown Norfolk, Virginia . Orders for Flight I ships continued through 1995. The Flight II iteration of

10530-499: The five Black Buck raids, three were against Stanley Airfield, with the other two being anti-radar missions using Shrike anti-radiation missiles . The Falklands had only three airfields. 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

10665-552: The forward Phalanx CIWS. Flight IIA ships were initially built without the AN/SQR-19 TACTAS, though later units were subsequently installed with TACTAS. Starting with USS  Winston S. Churchill  (DDG-81) , the longer 5-inch/62-caliber (127 mm) Mark 45 Mod 4 gun was installed. Later Flight IIA ships starting with USS  Mason  (DDG-87) use the BridgeMaster E as their navigation radar instead of

10800-617: The freezing water on the mountainside." Private Rito Portillo from the 1st Marine Anti-Aircraft Battalion and Private Remigio Fernández from the 5th Regiment were reported to have been executed or died because of mistreatment by their own officers. Soldiers were made to sign non-disclosure documents on their return from the Islands. On 8 April, Alexander Haig , the United States Secretary of State , arrived in London on

10935-479: The full $ 270 million Baseline 9 upgrade. Deputy of surface warfare Dave McFarland said that this change was due to the budget cuts in the Budget Control Act of 2011 . In 2016, the Navy announced it would begin outfitting 34 Flight IIA Arleigh Burke s with a hybrid-electric drive (HED) to lower fuel costs. The four LM2500 gas turbines of the class are most efficient at high speeds; an electric motor

11070-454: The hostilities. The conflict 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

11205-442: The islands and by using a late pop up profile. Meanwhile, other Argentine aircraft were intercepted by BAE Sea Harriers operating from HMS  Invincible . 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

11340-590: 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

11475-470: 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

11610-426: The islands to Argentina. 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

11745-619: The islands. For almost a month, the civilian population of Goose Green was detained in the village hall in "unpleasant conditions". 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

11880-415: The islands. 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

12015-584: The islands. The total Argentine garrison numbered some 13,000 troops by the beginning of May. 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

12150-415: 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

12285-570: The largest destroyers built in the United States; only the Spruance , Kidd (563 ft or 172 m), and Zumwalt classes (600 ft or 180 m) are longer. The Arleigh Burke class was designed with a new large, water-plane area-hull form characterized by a wide flaring bow, which significantly improves seakeeping ability and permits high speed in high sea states . The class's design incorporates stealth techniques , such as

12420-564: The last on 17 May narrowly avoided being shot down by the Chileans, leading to the cancellation of the operation. 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

12555-488: The latter's inability to counter emerging ballistic missiles, anti-ship missiles, and blue-water submarines. Arleigh Burke -class destroyers have been in production for longer than any other surface combatant class in the U.S. Navy's history. In April 2009, the Navy announced a plan limiting the Zumwalt class to three units while ordering another three Arleigh Burke -class ships from both Bath Iron Works and Ingalls Shipbuilding. In December 2009, Northrop Grumman received

12690-453: The living quarters and combat information center (CIC). The CIC is below the waterline. The Arleigh Burke class are multi-mission ships with numerous combat systems, including anti-aircraft missiles, land attack missiles, ship-to-ship missiles, and an anti-submarine warfare (ASW) system. Missiles are stored in and fired from Mark 41 Vertical Launching System (VLS) cells; with 90 cells on Flights I–II and 96 cells starting with Flight IIA,

12825-501: 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;

12960-520: 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

13095-612: The new radar. DDG MOD 2.0 will also deliver the AN/SLQ-32(V)7 EW suite, which adds the SEWIP Block 3 electronic attack subsystem. In May 2021, the Navy approved a "Smart Start Plan" for four ships—DDGs 91, 93, 95, 97—to make a gradual transition to DDG MOD 2.0. These ships will undergo a DDG MOD 1.5 phase that provides the SLQ-32(V)7; in 2023, DDG 91 became the first destroyer to receive SLQ-32(V)7. They will then receive

13230-645: 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

13365-517: The next day. On 5 April, the British government dispatched 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

13500-564: 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

13635-556: 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

13770-420: 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

13905-639: 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

14040-416: 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

14175-455: The originally-planned 80,000 shaft horsepower (shp) LM2500 gas turbines were upgraded to 100,000 shp. No main gun was included in the original design, later amended to include an OTO Melara 76 mm , before finally selecting the 5-inch/54-caliber Mark 45. Despite their constraints, the designers benefitted from insight gained from previous classes; for example, they chose an all-steel superstructure to improve survivability. The total cost of

14310-404: 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

14445-442: The planned Evolved SeaSparrow Missile; the Navy had initially decided that ESSM made Phalanx redundant. However, the Navy later changed its mind and decided to retrofit all IIA ships to carry at least one Phalanx CIWS by 2013. DDGs 91–96 (USS Pinckney , USS  Momsen , USS  Chung-Hoon , USS  Nitze , USS  James E. Williams , and USS  Bainbridge ) were built with superstructure differences to accommodate

14580-494: 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

14715-509: 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

14850-534: The rear-facing SPY-1D arrays are mounted one deck (eight feet) higher to prevent a blind spot. Flight IIA replaced retractable missile loading cranes on the forward and aft VLS with a total of six additional cells. The propellers are of a different design to reduce cavitation . New fiber optics improved bandwidth and helped reduce weight gain. Systems removed from Flight IIA include the Harpoon missile launchers and, starting with USS  McCampbell  (DDG-85) ,

14985-547: 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

15120-580: The ship can fire Mark 46 , Mark 50 , or Mark 54 lightweight torpedoes for short-range ASW. The ships can detect anti-ship mines at a range of about 1,400 meters. All ships of the class are fitted with at least one Phalanx close-in weapon system (CIWS), which provides point defense against air and surface threats. Eight ships ( DDG 51 , DDG 64 , DDG 71 , DDG 75 , DDG 78 , DDG 80 , DDG 84 , DDG 117 ) are equipped with one SeaRAM CIWS for improved self-defense. Arleigh Burke s can also carry two 25 mm Mk 38 machine gun systems , one on each side of

15255-679: The ship, designed to counter fast surface craft. There are numerous mounts for crew-served weapons like the M2 Browning . Located on the forward deck is the 5-inch (127 mm) Mark 45 gun . Directed by the Mark 34 Gun Weapon System , it can be used in anti-ship, anti-air, and naval gunfire support (NGFS) roles. It can fire 16–20 rounds per minute and has a range of 13 nautical miles (24 km). Arleigh Burke s can stow 680 5-inch rounds. As of 2023, six destroyers ( DDG 100 , DDG 104 , DDG 105 , DDG 106 , DDG 111 , DDG 113 ) are equipped with

15390-566: 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

15525-418: 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

15660-549: 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

15795-466: 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

15930-494: 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

16065-419: 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

16200-485: 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

16335-604: 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

16470-602: Was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic : the Falkland Islands and its territorial dependency , South Georgia and the South Sandwich Islands . The conflict began on 2 April 1982, when Argentina invaded and occupied the Falkland Islands , followed by the invasion of South Georgia

16605-534: 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

16740-713: 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

16875-473: 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,

17010-491: 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

17145-507: Was deployed with an AAI Aerosonde unmanned aerial vehicle (UAV). The aircraft is under demonstration for Flight I and II ships, which do not have accommodations for permanently storing helicopters. The Aerosonde has a small enough footprint to be stowed on those destroyers. It can perform missions such as intelligence, surveillance, and reconnaissance at a much lower cost than manned helicopters. The Chief of Naval Operations (CNO) from 1970 to 1974, Admiral Elmo Zumwalt , sought to improve

17280-756: Was expected to begin at-sea testing of the HELIOS in FY2023. Also by 2018, all Arleigh Burke -class ships homeported in the Western Pacific were scheduled to have upgraded ASW systems, including the TB-37U MFTA replacing the AN/SQR-19 TACTAS. In FY2019, the Navy started a program to procure the Mod 4 variant of the Mark 38 machine gun system to address "unmanned aerial systems (UAS) and high speed maneuverable unmanned surface vehicle (USV) threats." Mod 4 will incorporate

17415-589: 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

17550-540: 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

17685-456: 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

17820-414: 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

17955-597: 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,

18090-512: 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

18225-567: Was to be attached to the main reduction gear to turn the drive shaft and propel the ship at speeds under 13 knots (24 km/h), such as during BMD or maritime security operations. Use of the HED for half the time could extend time on station by 2.5 days before refueling. In March 2018, the Navy announced the HED would be installed on USS  Truxtun  (DDG-103) to test the technology, but upgrades of further destroyers would be halted due to changed budget priorities. Also in 2016, four destroyers of

#799200
