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 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 Bristol Type 171 Sycamore is an early helicopter developed and built by the helicopter division of the Bristol Aeroplane Company. The name refers to the seeds of the sycamore tree, Acer pseudoplatanus, which fall with a rotating motion. It has the distinction of being the first British helicopter to receive a certificate of airworthiness, as well as being the first British-designed helicopter to be introduced by and to serve with the Royal Air Force (RAF).
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.
The Sikorsky H-5 is a helicopter built by Sikorsky Aircraft Corporation.
The Westland Widgeon was a helicopter developed by Westland Aircraft as a private venture improvement on the Westland WS-51 Dragonfly.
The Bristol Type 173 was a British twin-engine, tandem rotor transport helicopter built by the Bristol Aeroplane Company. It was designed by Raoul Hafner as a civil transport helicopter but evoked interest from the military. It did not enter production but was developed into the Bristol Belvedere which was operated by the Royal Air Force from 1961 to 1969.
The North East Land, Sea and Air Museums (NELSAM), formerly the North East Aircraft Museum, is a volunteer-run aviation museum situated on the site of the former RAF Usworth/Sunderland Airport, between Washington and Sunderland, in Tyne and Wear, England. The museum has the largest aviation collection between Yorkshire and Scotland and houses over 30 aircraft and a wide collection of aero engines. The museum also has a small collection of other items such as weaponry, vehicles and other historical exhibits.
The Alvis Leonides is a British air-cooled nine-cylinder radial aero engine first developed by Alvis Car and Engineering Company in 1936.
The Percival Prince is a British light transport of the early postwar period. It was a twin-engine, high-wing, cantilever monoplane of all-metal stressed-skin construction; the undercarriage was of retractable, tricycle type.
The Sikorsky S-61R is a twin-engine helicopter used in transport or search and rescue roles. A developed version of the S-61/SH-3 Sea King, the S-61R was also built under license by Agusta as the AS-61R. The S-61R served in the United States Air Force as the CH-3C/E Sea King and the HH-3E Jolly Green Giant, and with the United States Coast Guard as the HH-3F, nicknamed "Pelican". This article covers several different variants of this type in different roles, one major difference compared to the S-61 was a rear ramp.
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 Sikorsky R-6 is an American light two-seat helicopter of the 1940s. In Royal Air Force and Royal Navy service, it was named the Hoverfly II.
The Australian Fleet Air Arm Museum, formerly known as Australia's Museum of Flight, is a military aerospace museum located at the naval air station HMAS Albatross, near Nowra, New South Wales. The museum was opened in 1990, although efforts to preserve artifacts related to Australia's naval aviation history began in 1974. The museum houses aircraft used throughout the history of the Fleet Air Arm, the naval aviation branch of the Royal Australian Navy (RAN), along with other aircraft of relevance to Australia's aviation history, and memorabilia relating to Australian aircraft carriers. The museum includes 34 aircraft and helicopters in its collection. It is open to the public daily, except for major public holidays. The museum building is also home to Albatross Aero Club.
772 Naval Air Squadron was a Naval Air Squadron of the Royal Navy's Fleet Air Arm which last disbanded during September 1995. 772 Naval Air Squadron formed as a Fleet Requirements Unit out of 'Y' Flight from 771 Naval Air Squadron at RNAS Lee-on-Solent in September 1939. While the headquarters remained there, floatplanes were operated out of RNAS Portland, however, mid 1940 saw the whole squadron move north to RNAS Campbeltown and roughly twelve months afterwards the short distance to RNAS Machrihanish. The unit moved to RNAS Ayr in July 1944 and became the Fleet Requirements Unit School. In January 1946 the squadron moved to RNAS Burscough in Lancashire, before moving to RNAS Anthorn in Cumberland, in May. It became the Northern Fleet Requirements Unit upon moving to RNAS Arbroath, in June 1947, but disbanded into 771 Naval Air Squadron in October. 772 Naval Air Squadron reformed as a Helicopter Support Squadron at RNAS Portland in September 1974. In September 1977 the squadron took over responsibility for a number of Ships' Flights of Royal Fleet Auxiliary ships. The squadron was used to reform 848 Naval Air Squadron for the Falklands Task Force in 1982, with the Ships' Flights absorbed into 847 Naval Air Squadron. In August 1982 it took on the Anti-Submarine Warfare Flight from 737 Naval Air Squadron and between 1983 - 1985 a Search and Rescue Flight operated out of RNAS Lee-on-Solent.
