The following are operators of the Sikorsky H-19 Chickasaw and Westland Whirlwind. helicopters. This helicopter was operated globally with many operators military in the late 20th century.
The Sikorsky MH-60/HH-60 Pave Hawk is a four-blade, twin-engine, medium-lift utility military helicopter manufactured by Sikorsky Aircraft. The HH-60 Pave Hawk and its successor the HH-60W Jolly Green II are combat rescue helicopters, though in practice they often serve humanitarian and peacetime disaster rescue. It is a derivative of the UH-60 Black Hawk and incorporates the US Air Force PAVE electronic systems program. The HH-60/MH-60 is a member of the Sikorsky S-70 family.
The Sikorsky SH-3 Sea King is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft. A landmark design, it was one of the first ASW rotorcraft to use turboshaft engines.
The Westland Whirlwind helicopter was a British licence-built version of the U.S. Sikorsky S-55/H-19 Chickasaw. It primarily served with the Royal Navy's Fleet Air Arm in anti-submarine and search and rescue roles. It was also exported to other countries, and the Whirlwind was succeeded by the turbine powered Westland Wessex which was developed from the H-19/Whirlwind. The helicopter was made in many variants using a variety of radial (piston) and turbine engines.
The Westland Wessex is a British-built turbine-powered development of the Sikorsky H-34. It was developed and produced under licence by Westland Aircraft. One of the main changes from Sikorsky's H-34 was the replacement of the piston-engine powerplant with a turboshaft engine. Early models were powered by a single Napier Gazelle engine, while later builds used a pair of de Havilland Gnome engines.
The Westland WS-61 Sea King is a British licence-built version of the American Sikorsky S-61 helicopter of the same name, built by Westland Helicopters. The aircraft differs considerably from the American version, with Rolls-Royce Gnome engines, British-made anti-submarine warfare systems and a fully computerised flight control system. The Sea King 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.
The AgustaWestland AW101 is a medium-lift helicopter in military and civil use. First flown in 1987, it was developed by a joint venture between Westland Helicopters in the United Kingdom and Agusta in Italy in response to national requirements for a modern naval utility helicopter. Several operators, including the armed forces of Britain, Denmark, and Portugal, use the name Merlin for their AW101 aircraft. It is manufactured at factories in Yeovil, England, and Vergiate, Italy. Licensed assembly work has also taken place in Japan and the United States.
The Sikorsky H-19 Chickasaw is a multi-purpose piston-engined helicopter that was used by the United States Army and United States Air Force. It was also license-built by Westland Aircraft as the Westland Whirlwind in the United Kingdom. United States Navy and United States Coast Guard models were designated HO4S, while those of the U.S. Marine Corps were designated HRS. In 1962, the U.S. Navy, U.S. Coast Guard and U.S. Marine Corps versions were all redesignated as H-19s like their U.S. Army and U.S. Air Force counterparts.
The Mil Mi-4 is a Soviet transport helicopter that served in both military and civilian roles.
The Sikorsky H-34 is an American piston-engined military utility helicopter originally designed by Sikorsky as an anti-submarine warfare (ASW) aircraft for the United States Navy. A development of the smaller Sikorsky H-19 Chickasaw (S-55), the H-34 was originally powered by a radial engine, but was later adapted to turbine power by the British licensee as the Westland Wessex and by Sikorsky as the S-58T. The H-34 was also produced under license in France by Sud Aviation.
The Sikorsky R-4 is a two-seat helicopter that was designed by Igor Sikorsky with a single, three-bladed main rotor and powered by a radial engine. The R-4 was the world's first large-scale mass-produced helicopter and the first helicopter used by the United States Army Air Forces, the United States Navy, the United States Coast Guard and the United Kingdom's Royal Air Force and Royal Navy. In U.S. Navy and U.S. Coast Guard service, the helicopter was known as the Sikorsky HNS-1. In British service it was known as the Hoverfly.
RNAS Portland was an air station of the Royal Navy, situated at the Isle of Portland, Dorset, England. It was established in 1917 on the western edge of Portland Harbour as HMS Sarepta. From 1959 the station shared the name HMS Osprey, the anti-submarine establishment based at Portland, with helicopters used for research and development in anti-submarine techniques. RNAS Portland remained operational until 1999.
The Westland Widgeon was a helicopter developed by Westland Aircraft as a private venture improvement on the Westland WS-51 Dragonfly.
The Bristol Type 192 Belvedere is a British twin-engine, tandem rotor military helicopter built by the Bristol Aeroplane Company. It was designed by Raoul Hafner for a variety of transport roles including troop transport, supply dropping and casualty evacuation. It was operated by the Royal Air Force (RAF) from 1961 to 1969. The Belvedere was Britain's only tandem rotor helicopter to enter production, and one of the few not built by Piasecki or Boeing.
The Westland WS-51 Dragonfly helicopter was built by Westland Aircraft and was an Anglicised licence-built version of the American Sikorsky S-51.
The AgustaWestland AW139, now known as the Leonardo AW139, is a 15-seat medium-sized twin-engined helicopter developed and produced by the Italian helicopter manufacturer AgustaWestland, now part of Leonardo. It is marketed at several different roles, including VIP/corporate transport, military use, offshore transport, firefighting, law enforcement, search and rescue, emergency medical service, disaster relief, and maritime patrol.
705 Naval Air Squadron was first formed as a flight in 1936 from No 447 Flight Royal Air Force and operated Swordfish torpedo bombers from battlecruisers. It achieved squadron status in 1939 before being disbanded in 1940. The squadron was re-formed briefly in 1945 and then again in 1947 as a fleet requirements unit to evaluate naval use of helicopters. Since the 1950s the squadron has been involved in the basic training of helicopter aircrew, and currently forms part of No. 1 Flying Training School at RAF Shawbury.
The Royal Air Force Search and Rescue Force was the Royal Air Force organisation which provided around-the-clock aeronautical search and rescue cover in the United Kingdom, Cyprus and the Falkland Islands, from 1986 until 2016.
737 Naval Air Squadron was a Naval Air Squadron of the Royal Navy's Fleet Air Arm. It was initially active during 1943 as an amphibious Bomber Reconnaissance Training Squadron. Reactivated in 1944 it operated as an ASV Training Unit until 1945. It was active again between 1949 and 1957. From 1959 it was the Anti-Submarine Warfare school at RNAS Portland. It operated Westland Wessex HAS.3 rescue helicopters from their land base at RNAS Portland, Dorset.
728C Naval Air Squadron was a Naval Air Squadron of the Royal Navy's Fleet Air Arm (FAA). It was active between January and October 1958 as the Amphibious Warfare Trials Unit. Equipped with four Westland Whirlwind HAS.22 helicopters, the squadron operated around the Mediterranean Basin before it was redesignated 848 Naval Air Squadron on achieving first line status.
