The SAS lost 18 men in the crash, their highest number of casualties on one day since the Second World War . The Royal Signals lost one man and the RAF one man. During the 1991 Gulf War Sea Kings from several nations, including Canada, Britain, and the U.S., were present in the coalition forces against Saddam Hussein 's Iraq regime. Due to
408-548: A SAR flight in the islands, initially from Navy Point on the north side of Stanley harbour, and later from RAF Mount Pleasant. In 1992, six further helicopters were ordered to replace the last remaining Westland Wessex helicopters in the SAR role, entering service in 1996. However, teething problems resulted in the actual operational use of the HAR3A's being delayed until mid 1997. The six Sea King HAR3As featured updated systems, including
544-436: A Sea King to conduct a water landing and, being completely watertight, would enable the rotorcraft to remaining floating for prolonged periods on the ocean's surface. Deployable airbags in the aircraft's sponsons added to the rotorcraft's stability and buoyancy, resisting pitching and rolling. The hull design was compatible with landing on challenging terrain, including ice, snow, swamp land, and tundra. Wheels are installed in

A team of Indian engineers was sent to Britain to help develop the Mk42B's avionics, especially
1088-634: A different crew arrangement, with operations being controlled by an observer rather than the pilot, as well as fitting a search radar. The Royal Navy selected the Sea King to meet a requirement for an anti-submarine warfare (ASW) helicopter to replace the Westland Wessex , placing an order with Westland for 60 SH-3D Sea Kings in June 1966. The prototype and three pre-production aircraft were built by Sikorsky at Stratford, Connecticut and shipped to
1224-619: A digital navigation system and more modern avionics. Westland also manufactured SAR versions of the Sea King for the Royal Norwegian Air Force, the German Navy and the Belgian Air Force . On SAR variants, the cabin was enlarged by a stretch of the fuselage behind the door; another key feature, used for additional flotation in the unusual event of a water landing, inflatable buoyancy bags were housed inside
1360-581: A logistical capacity at sea, transferring personnel, mail, and other lighter cargoes between vessels. The Royal Canadian Navy (RCN) became a major operator of the Sikorsky CH-124 Sea King following its introduction to service in 1963.

3808-653: The Fairey Gannet aeroplane was withdrawn after the last of the RN's fleet carriers was decommissioned in 1978. During the Falklands War, a number of warships were lost and casualties suffered due to the lack of an AEW platform. The proposed fleet cover by the RAF Shackleton AEW.2 was too unresponsive and at too great a distance to be practical. Consequently, two Sea King HAS2s were modified in 1982 with
3944-573: The HAS2 , HAS5 and HAS6 . Changes from initial production aircraft included an expansion of the cabin and upgraded engines. One of the most extensively modified variants was the Westland Commando , operated by the Royal Navy as the HC4. The Commando had capacity for up to 28 fully equipped troops and had originally been developed to meet an Egyptian Air Force requirement. Due to the deletion of

As the Sea King was too large to operate from the Adelaide -class frigates , 817 Squadron was then forced to operate from land bases, in both ASW and utility roles, with the Sea King relinquishing the anti-submarine mission in 1990. During the 2003 Iraq War, Sea Kings were heavily used in logistical roles, such as the first delivery of humanitarian aid to
9656-417: The carrier's primary anti-submarine aircraft. During the early 1960s, India and Britain agreed upon the domestic production of the Leander -class frigate . The initial helicopter deployed aboard India's Leander s, known as the Nilgiri class , was the Aérospatiale Alouette III , however, this offered much less capability in the anti-submarine role compared with the Sea King and the need for design changes
9792-571: The cessation of hostilities. A further eight HAS2s were modified to a production standard, known as the AEW2 . Two remained "fitted for but not with". These entered operational service in 1985, being deployed by 849 Naval Air Squadron . Three Sea King HAS5/6s were later converted as part of the ASaC Mk7 programme, bringing the Mk7 fleet to 13; still 3 below the requirement. The upgrade programme resulted in
9928-482: The combat zone and operated from the decks of various ships of the Royal Navy, such as the landing platform dock HMS Fearless . In the theatre, they performed a wide range of missions, from anti-submarine patrols and reconnaissance flights to replenishment operations and the insertion of special forces . Support provided by the Sea Kings in the form of transport for men and supplies has been viewed as vital to
10064-633: The command of the Joint Rescue Coordination Centre of Southern Norway and Northern Norway . Introduced in May 1973, they were originally stationed at Bodø Main Air Station , Ørland Main Air Station , Sola Air Station and Station Group Banak . In 1997, the squadron conducted 237 SAR and 747 air ambulance missions. From 1995 to 1998, one helicopter was stationed at Ålesund Airport, Vigra , and since 1999, one has been stationed at Rygge Air Station . Florø Airport became
10200-516: The controlled environment of a hangar , and when completed Walrus was passed operational and ready to be used for different sensor and payload tests. In 2023 a new flight was formed by 700X Naval Air Squadron to learn how to maintain and safely operate the QinetiQ Banshee Jet 80+ . The Banshee Jet 80+ drones can achieve above 400 miles per hour (640 km/h) and are of capable more than 60 miles (97 km) range. The 3m x 2.5m drone
10336-475: The detection and tracking of Soviet submarines. In the event of open warfare breaking out between the two powers, Sea Kings would have been used to attack these submarines with the intent to sink them. The Sea King was able to operate from the flight decks of many of the US Navy's vessels as well as shore bases. It could also operate from offshore platforms to extend their surveillance and strike ranges. The type
10472-416: The development of an entirely new rotorcraft. A total of ten prototypes were produced to support the development program. On 11 March 1959, the first prototype conducted its maiden flight . During early 1961, a pair of prototypes were stationed on board the aircraft carrier Lake Champlain to fulfill a demand for carrier suitability trials. These trials, which involved testing the folding mechanism of
10608-436: The development of the Sea King. During the late 1950s, the US Navy took advantage of recent aerospace advances, such as the turboshaft engine, by commissioning the development of a new large naval helicopter. Sikorsky received a request from the service to design a new turbine-powered helicopter that would be capable of performing the ASW mission. The specification included a dipping sonar , mission endurance of four hours, and
10744-491: The differences between the Westland-built Sea King and the original helicopter were as a result of differing operational doctrine. While the U.S. Navy Sea Kings were intended to be under tactical control of the carrier from which they operated, the Royal Navy intended its helicopters to be much more autonomous, capable of operating alone, or co-ordinating with other aircraft or surface vessels. This resulted in
10880-435: The emerging ASW helicopter included its amphibious hull , which enabled the rotorcraft to readily perform water landings, and its adoption of a twin-turboshaft engine arrangement that enabled it to be larger, heavier and better-equipped than had been possible with prior helicopters. The designation HSS-2 was applied, allegedly to imply a level of commonality to the earlier HSS-1 , should political sentiment turn against
11016-706: The end of the Sea King's operational life, several HAS6s were repurposed by the removal of the ASW equipment, as troop transports. In 2010, the last of the UK's converted ASW Sea Kings to troop transports were retired. In the 1970s, Westland's experience with the Sea King led the company to conduct the British Experimental Rotor Program (BERP), in coordination with the Royal Aircraft Establishment , which applied innovations in composite materials and new design principles to
11152-698: The evacuation of British citizens from Lebanon . In October 2011, following several years of service in Afghanistan as troop transports for the International Security Assistance Force (ISAF) forces stationed there, the Sea King HC.4s returned to the UK; their replacement is the AgustaWestland AW101 Merlin. Between April 2009 and July 2011, the Royal Navy's Sea Kings stationed at Camp Bastion conducted over 1000 operational missions. The last Sea King flight in service
11288-460: The face of operational needs. The NH-3A (S-61F) was an experimental high-speed compound helicopter based on the Sea King tested in the 1960s. Later modified with a tail rotor able to rotate 90° to serve as a pusher propeller; this helicopter demonstrated "Roto-Prop" pusher propeller for Sikorsky's S-66 design . In addition to those Sea Kings that were manufactured by Sikorsky, several license agreements were enacted with other firms to produce
11424-572: The first Sea King was videoed being used by the Ukrainian Naval Aviation . In April 2023, the BBC did an interview with one of the co-pilots of a UK donated Sea King to Ukraine. These helicopters served in the Falklands War so they are at least some 40 years old. The co-pilot has said that the Sea King is used for rescuing pilots who have ejected, delivering soldiers, and conducting reconnaissance, among other tasks. One engineer also told
11560-416: The flagship HMS Hermes . On 12 May, a Sea King operating from Hermes crashed into the sea due to an altimeter problem; all crew were rescued. On 19 May 1982 a Sea King, in the process of transporting SAS troops to HMS Intrepid from Hermes , crashed into the sea while attempting to land on Intrepid . Twenty-two men were killed and nine survived. Bird feathers were found in the debris, suggesting
11696-615: The flight were the Flight Commander who integrated the Puma with the ship, the mission operator who flew the Puma and the vehicle operator who controlled the camera. As of 2021, twelve Puma systems were deployed with the squadron permitting individual teams to be embarked on Royal Navy vessels as might be required. In 2024, the Navy reported that there were a total of nine qualified Puma teams, six of which were dedicated to supporting
11832-430: The ground advance. There was thorough radar coverage by U.S. airborne early warning and control (AWACS) aircraft; British AEW Sea Kings were not deployed. Following the end of hostilities, the available Sea Kings remained on deployment in the region to conduct transport missions to relocate people displaced by the conflict to refugee camps and repatriate citizens to their home countries. The Sea King participated in
11968-799: The introduction into the Fleet Air Arm of the anti-submarine warfare and utility helicopter, the Westland Wessex , the Blackburn Buccaneer attack aircraft , the McDonnell Douglas F-4 Phantom II , an interceptor and fighter-bomber , the Westland Sea King anti-submarine, medium-lift transport and utility helicopter, the Westland Lynx multi-purpose helicopter and British Aerospace Sea Harrier , amongst other aircraft. More recently,
12104-518: The main rotor blades and a series of takeoffs performed during winds of up to 50 mph (80 km/h), were completed successfully in mid-1961. Shortly after the completion of suitability trials, the US Navy formally accepted delivery of the first HSS-2 rotorcraft, which was subsequently re-designated as the SH-3A, in September 1961. In late 1961 and early 1962, a modified US Navy HSS-2 Sea King
12240-417: The main successor. Following the Indo-Pakistani War of 1965 , Pakistan invested heavily in modern submarines and long-range torpedoes. In response, India opted to procure six Westland Sea Kings from Britain in 1969, for ASW duties, designated as Mk42 . The purchase also included the provision of air-droppable homing torpedoes for use against submarines. The delivery of the aircraft began a few months before
12376-580: The manufacture of some components by Hindustan Aeronautics Limited (HAL). In December 2000, President Bill Clinton permitted a relaxation of the sanctions. In the late 2000s, HAL and AgustaWestland signed an agreement to jointly maintain and perform upgrades to India's fleet of Sea Kings. The Norwegian Ministry of Justice owns 12 Mk43B Sea Kings which are operated by the Royal Norwegian Air Forces's 330 Squadron . The aircraft are used for SAR and air ambulance missions and are under
12512-532: The new radar enables the ASaC7 to simultaneously track up to 400 targets, instead of an earlier limit of 250 targets. The effectiveness of the AEW7 was greatly increased via the addition of a Link 16 data link, allowing gathered radar information to be analysed and rapidly put to use by multiple allied platforms in range. The ASaC7s remained in service until they were replaced under the "Crowsnest" programme; intended as
12648-577: The onboard software. Changes from the older Sea Kings included a brand new avionics suite, the use of composite materials throughout the fuselage and in the rotor blades, as well as the integration of the Sea Eagle missile , which had been procured from Britain in 1983. Between 1988 and 1992, a total of 20 Mk42B Sea Kings were delivered to the Indian Navy. Six Sea Kings in troop-carrying capacity, designated Mk42C , were also procured in 1987. Although
12784-665: The primary causes were the loss of oil from the main gearbox. The Australian Sea Kings had similar avionics to that of the Sea King HAS.1, with the same ARI 5995 search radar in a dorsal radome, but had American Bendix AN/AQS-13A dipping sonar instead of the Plessey sonar of the Royal Navy Sea Kings. They also had more powerful engines giving improved high temperature hover performance. Australia's Sea Kings were flown by 817 Squadron RAN from HMAS Melbourne until
12920-571: The region and delivered aid relief to citizens in the flooded areas. The replacement of the Fleet Air Arm's Sea King fleet commenced faster than initially planned following the loss of a Sea King during a humanitarian aid mission in Indonesia in April 2005, resulting in nine deaths. Investigators uncovered serious faults in the condition of the Sea King's mechanical flight control system, resulting from maintenance deficiencies. In May 2007,
13056-475: The sea killing all three crew. In November the squadron took over the 701 Naval Air Squadron aircraft which were operating from Stornoway harbour and this became known as 700 Stornoway Flight. In March 1941 this Flight moved to RAF Sullom Voe and joined the Shetland Flight, but this then disbanded in May when RAF aircraft became available. Trailing Kriegsmarine capital ships in the lead up to
13192-648: The ship's Limbo anti-submarine mortar . Beyond the original 1971 procurement, India chose to acquire a further six Mk42s in 1974, and three more in 1980; these three had been specifically modified to operate from the flight deck of the last two Nilgiri s and designated as Mk42A . As a follow-on to the Nilgiri s, India commenced development of a new frigate, based on the Leander / Nilgiri , but larger. The resultant Godavari class , also known as Project 16, could operate two Sea Kings simultaneously. In 1982, India signed
13328-708: The six remaining Sea Kings were grounded for two months following the discovery of a number of missing parts. On 1 September 2011, the Australian Minister for Defence Materiel, Jason Clare , announced that the Sea Kings would be withdrawn from service in December 2011; having flown in excess of 60,000 hours in operations in Australia and overseas in that time. The farewell flight was conducted on 15 December 2011, three Sea Kings flew over Sydney Harbour and across to Canberra , passing Lake Burley Griffin and
13464-474: The sponsons for land operations. The armament fitted upon a Sea King could vary considerably. For anti-submarine missions, the aircraft could carry up to four torpedoes or four depth charges. For anti-ship duties, some models were outfitted to carry one or two missiles, typically Sea Eagles or Exocets . The Sea King could also be fitted to deploy the B57 nuclear bomb . ASW equipment used on Sea Kings has included
13600-494: The squadron began trials on HMS Lancaster with the Peregrine rotary-wing UAV . The rotary-wing UAV was designed to operate alongside its regular helicopter detachment and provide enhanced surveillance capabilities to the frigate. The battle honours awarded to 700 Naval Air Squadron are: 700 Naval Air Squadron operated from a number of naval air stations of the Royal Navy , Royal Air Force stations and other airbases in
13736-499: The squadron had three flights, operating with the AeroVironment RQ-20 Puma system, for deployment. These were designated Phantom Flights A, B and C, with each flight made up of a commander, an air engineering technician and a naval airman. The initial operational test was during the name ship of her class HMS Albion 's Mediterranean deployment. To operate the Puma system, the three personnel who made up
13872-479: The squadron moved to RNAS Middle Wallop (HMS Flycatcher ) , on 23 November 1945. It moved again the following April when it 1946 the squadron relocated to RNAS Yeovilton (HMS Heron ) , Somerset and where in May 1948 it became part of the 50th Training Air Group . 700 Maintenance Test Pilots training Squadron disbanded in September 1949. 700 Naval Air Squadron reformed as a Trials and Requirements Unit on 18 August 1955 at RNAS Ford (HMS Peregrine ) , Sussex. It
14008-683: The squadron moved to RNAS Yeovilton (HMS Heron ). In January 1956, when 787 Naval Air Squadron disbanded, 700 NAS took over its duties, however, in February 1957 the Fleet Requirements work was given to Airwork Services Ltd at Hurn . The squadron moved to RNAS Yeovilton in September 1958 where it later disbanded in July 1961. The Squadron carried on trials of de Havilland Sea Vixens on HMS Victorious and HMS Centaur during 1958 and from October 1959 formed at Yeovilton with
14144-673: The squadron was re-commissioned at RNAS Culdrose (HMS Seahawk ) in Cornwall during December 1998 as 700M Naval Air Squadron, with a primary role as an Intensive Flying Trials Unit (IFTU) of testing and evaluating the AgustaWestland Merlin HM.1 helicopter. In September 2001 the unit became the Operational Evaluation Unit (OEU) for the Fleet Air Arm's Merlin helicopter. In 2002 the OEU deployed to both

Sea Kings also protected the fleet by acting as decoys against incoming Exocet missiles , with some missions being flown by Prince Andrew, Duke of York . Anti-Submarine Sea Kings of 820 Naval Air Squadron were embarked in HMS ; Invincible . With 11 HAS.5s, the squadron operated anti-submarine and search and rescue sorties with one helicopter always airborne on surface search duties. On 14 June, an 820 NAS Sea King HAS.5
14416-482: The threat of potential use of any Iraqi weapons of mass destruction , it was standard practice for Sea King crews to wear fully enclosed NBC (nuclear, biological, chemical) protective suits . Britain's Sea Kings primarily engaged in inter-ship transport duties, including ferrying troops between the fleet and land. Six Sea King Mk4 helicopters from 845 Naval Air Squadron and six of 848 Squadron , which had been reformed to meet this operational demand, worked in support of
14552-647: The three main areas of degradation between the Mk2 and Mk7. (NVG, Anti-Collision lighting and Interoperability with ships). These had been identified and two contracts let to mitigate the risks had been cancelled by an administrative official. Moreover, in 1994 the RN had rejected the recommendation of the programme manager to retain NVG. In July 2006, Sea King HC.4 helicopters based at RNAS Yeovilton were temporarily deployed to Cyprus to assist in Operation Highbrow,
14688-774: The two Queen Elizabeth -class aircraft carriers. The UK has also planned to retire the HC4 and search and rescue variants in March 2016. A dedicated search and rescue (SAR) version, the HAR3 , was developed for the RAF Search and Rescue Force . The type entered service in 1978 to replace the Westland Whirlwind HAR.10 . A 16th helicopter was ordered shortly after, and following the Falklands War of 1982, three more instances were purchased to enable operation of
14824-624: The type remain in service in nations around the world, although some major users have begun to retire the type. The Sea King has been built under license by Agusta in Italy, Mitsubishi in Japan, Canada by United Aircraft of Canada , and by Westland in the United Kingdom as the Westland Sea King . The major civil versions are the S-61L and S-61N . The S-61R was another important variant, which

Another noteworthy Sea King variant, the significant change this time being the adoption of a conventional fuselage, the Sikorsky S-61R , was also concurrently developed for transport and search and rescue (SAR) duties, this type being extensively operated by the U.S. Air Force and the U.S. Coast Guard . In US Navy service, the initial SH-3A model of
15096-672: The type. These included the Japanese conglomerate Mitsubishi and the Italian aerospace company Agusta . Another licensee was the British helicopter manufacturer Westland Helicopters , which substantially redesigned the Sea King to produce various models of their own, collectively referred to as the Westland Sea King . In contrast to the US Navy's Sea Kings, the Westland Sea King was intended for greater operational autonomy. In total, Westland produced 330 Sea Kings; outside of its British-based operators, various export customers were found for

It is powered by a pair of Rolls-Royce Gnome turbines (license-built T58s), and has British avionics and ASW equipment. This variant first flew in 1969, and entered service the next year. It was until 2017 also used by the Royal Air Force in a search and rescue capacity, and has been sold to many countries around
15504-463: Was 826 Naval Air Squadron with nine HAS.5s, which carried out continuous anti-submarine sorties. From the departure of Hermes from Ascension in April until the Argentine surrender, the squadron operated at least three helicopters airborne continuously for fleet protection. On 23 April 1982, a Sea King HC4 was ditched while performing a risky transfer of supplies to a ship at night, operating from
15640-422: Was also the first helicopter to be procured under the US Navy's new weapon system concept, under which Sikorsky was responsible not only for the design and production of the airframe, but all major onboard systems, such as the sonar , navigational equipment, electronic devices, and support equipment. As such, the navigation suite for the rotorcraft was developed jointly by Sikorsky and the US Navy. Key features of
15776-592: Was bombed by Walrus L2268 of 700 NAS from HMS Devonshire and attacked by HMS Milford on 7 November 1940 off the Cameroons . The submarine was damaged and forced to surrender, and later scuttled off the Gulf of Guinea . The crew of Petty Officer P H Parsons, Sub Lt A D Corkhill and N A Evans were all awarded gallantry medals. By the middle of 1943 the squadron strength was down to twenty aircraft as radar made catapult launched aircraft unnecessary. What
15912-475: Was capable of conducting nighttime ASW operations, albeit these usually posed considerable difficulty for the flight crew. The Sea King also performed various other roles and missions such as search-and-rescue, transport, anti-shipping and airborne early warning operations. Aircraft carriers would typically deploy Sea Kings to operate near the carrier as a plane guard , ready to rescue air crew who crashed during takeoff or landing. They were routinely used in
16048-547: Was conducted by Westland and GEC-Marconi. This variant was initially referred to as the Sea King AEW7 , but renamed ASaC7 (Airborne Surveillance and Control Mk.7) just before In Service Date. The main role of the Sea King ASaC7 is detection of low-flying attack aircraft; it also provides interception/attack control and over-the-horizon targeting for surface-launched weapon systems. In comparison to older versions,
16184-636: Was disbanded in July 2014 when it was merged with 702 Naval Air Squadron to form 825 Naval Air Squadron , the first operational FAA AgustaWestland Wildcat unit. In October 2014 the squadron reformed as 700X Naval Air Squadron at RNAS Culdrose (HMS Seahawk ), Cornwall. It was initially tasked with Operational Test and Evaluation (OT&E) for the Boeing Insitu ScanEagle an unmanned surveillance and reconnaissance aerial vehicle . The squadron has been setup to undertake Remotely Piloted Air Systems (RPAS) trials, and it previously acted as
16320-434: Was equipped with the multirole training aircraft Avro Anson , Fairey Firefly TT.4 target tug, de Havilland Sea Vampire F.20 fighter-bomber, Hawker Sea Hawk day fighter, Westland Wyvern strike aircraft and Fairey Gannet anti-submarine aircraft. 703 STU and 771 FRU had disbanded at RNAS Ford the previous day and they were successfully combined to form 700 Trials and Requirements Unit. One month later, on 19 September
16456-559: Was formed for the war with 10 Sea King HAS.2s modified as utility variants to support ground forces. The anti-submarine equipment was removed and the helicopters fitted with troop seats. Two aircraft embarked in Queen Elizabeth 2 and were later used for moving troops from QE2 to other ships, the remainder embarked in Atlantic Causeway and were used for troop movements around the islands. Embarked in HMS Hermes
16592-457: Was in September 2018, marking an end to half a century of service with the Royal Navy. In 1974, Australia purchased 12 Westland Sea King Mk 50s as the Royal Australian Navy 's new ASW helicopter; the Sea Kings replaced the aircraft carrier HMAS Melbourne 's complement of Westland Wessex HAS31 in the following year. Early operations were troubled by a series of accidents. Between October 1975 to May 1979, four aircraft were lost in accidents,
16728-422: Was initially capable of generating up to 1,250 shp (930 kW) each. In normal operations, the Sea King typically would have a four-man crew on board; these being a pilot and copilot in the cockpit, and two aircrew stationed within the main cabin area. When conducting anti-submarine missions, the rear aircrew operated the aircraft's sensors and interpreted the generated data. For search-and-rescue missions,
16864-542: Was initially designated HSS-2 , which was intended to imply a level of commonality to the earlier HSS-1 ; it was subsequently redesignated as the SH-3A during the early 1960s. Introduced to service in 1961, it was operated by the United States Navy as a key ASW and utility asset for several decades prior to being replaced by the non-amphibious Sikorsky SH-60 Seahawk in the 1990s. In late 1961 and early 1962,
17000-499: Was initially equipped with forty-two Supermarine Walrus flying boats, together with eleven Fairey Seafox and twelve Fairey Swordfish floatplanes . On 21 June 1940, a Walrus ( P5666 ) of 700 Squadron on the cruiser HMS Manchester found the German battleship Scharnhorst but Manchester did not engage. From July, the squadron absorbed small number of Supermarine Walrus operated from RAF Sullom Voe , designated as
17136-566: Was left of A' Flight became 'B' Flight of 771 Naval Air Squadron at RNAS Hatston and 700 Naval Air Squadron disbanded on 24 March 1944. 700 Naval Air Squadron reformed on 11 November 1944 as the Maintenance Test Pilot Training Squadron at RNAS Donibristle (HMS Merlin ). It later moved to RNAS Worthy Down (HMS Kestrel ) , Hampshire, and became part of the School of Aircraft Maintenance, operating with
17272-507: Was one of the first ASW rotorcraft to use turboshaft engines. The Sea King has its origins in efforts by the United States Navy to counter the growing threat of Soviet submarines during the 1950s. Accordingly, the helicopter was specifically developed to deliver a capable ASW platform; in particular, it combined the roles of hunter and killer , which had previously been carried out by two separate helicopters. The Sea King
17408-635: Was primarily designed for performing anti-submarine warfare (ASW) missions. A Sea King variant known as the Commando was developed by Westland to serve as a troop transport. In British service, the Westland Sea King provided a wide range of services in both the Royal Navy and the Royal Air Force . As well as wartime roles in the Falklands War , the Gulf War , the Bosnian War , the Iraq War and
17544-479: Was realised to allow the Sea King to be deployed upon the flight deck of the Nilgiri class, a practice pioneered by the Royal Canadian Navy using their Sikorsky CH-124 Sea Kings on similar-sized frigates. It proved unfeasible to operate the Sea King from the unmodified Nilgiri class, with the last two ships of the class being fitted with an enlarged flight deck and hangar. This required removal of
17680-609: Was short-listed to conduct further discussions for the NAWSARH programme for up to 16 helicopters. The German Navy placed an order for 22 Sea King Mk.41s on 20 June 1969 as a replacement for the Grumman Albatross flying boat in the Search and Rescue Role. This was the first export sale for the Westland Sea King, and was the first dedicated Search and Rescue Sea King variant, with an enlarged cabin and more fuel. The German Sea Kings had similar radar and navigation equipment to
17816-520: Was spent at RNAS Dundee (HMS Condor II) , a seaplane base / repair depot, in Dundee , where the focus was on water operations, which included night landings. Week seven was a catapult course aboard HMS Pegasus , a Royal Navy aircraft carrier/ seaplane carrier , in the Irish Sea . Week eight was then a return to RNAS Donibristle (HMS Merlin ). The final successful attack on an enemy submarine by
17952-777: Was the CH-3C/E Sea King, used by the U.S. Coast Guard as the HH-3F Pelican, and the Air Force's HH-3E Jolly Green Giant; this version had a ramp at the rear among other changes. During the Cold War , the Soviet Navy built up a large and varied fleet of submarines which at one point was in excess of 200 operational submarines. The US Navy countered this threat by the improvement and development of various anti-submarine warfare (ASW) capabilities, which resulted in
18088-450: Was the primary helicopter for retrieving manned space capsules starting with Mercury-Atlas 7 in May 1962. Helicopter 66 was the primary recovery vehicle for Apollo missions 8 and 10 to 13. In February 1971, an SH-3A, operating from the amphibious assault ship USS New Orleans , recovered Apollo 14 . A specialist search and rescue variant of the SH-3, the HH-3, also performed in this capacity. Several Sea Kings, operated by
18224-466: Was the use of a winch 'hauldown' landing and securing method, referred to as a ' Beartrap '. This device considerably increased the ability of Sea Kings to land in difficult conditions, such as on small flight decks or during poor weather conditions. The Sea King was exported in large numbers to various nations, such as Brazil , Italy , Japan and the United Kingdom . Several operators have kept their Sea Kings in use for more than 50 years. During
18360-430: Was used to break the FAI 3 km, 100 km, 500 km and 1000 km helicopter speed records. This series of flights culminated on 5 February 1962 with the HSS-2 setting an absolute helicopter speed record of 210.6 mph (338.9 km/h). This record was broken by a modified French Sud-Aviation Super Frelon helicopter on 23 July 1963 with a speed of 217.77 mph (350.47 km/h). The base design of
18496-540: Was used to transport Major General Jeremy Moore to Port Stanley to accept the surrender of Argentine troops on the island. The squadron flew 1,650 sorties during the war.
