The '''Westland Whirlwind''' [[helicopter]] was a British [[licence-built]] version of the U.S. [[Sikorsky Aircraft|Sikorsky]] [[Sikorsky H-19 Chickasaw|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]] (based on the [[Sikorsky H-34]]) which was developed from the H-19/Whirlwind. The helicopter was made in many variants using a variety of radial (piston) and turbine engines.

Whirlwind helicopters fitted with turbine power served right up until the early 1980s, and a converted Whirlwind was in the [[Air transport of the British royal family and government|Queen's Flight]].

==Design and development==
[[File:Westland Whirlwind 1 G-AOCZ BLA 05.09.55 edited-2.jpg|thumb|left|Whirlwind Series 1 demonstrator fitted with P&W R-1340 in 1955]]
In 1950, [[Westland Aircraft]], already building the American [[Sikorsky H-5|Sikorsky S-51]] under licence as the [[Westland Dragonfly]], purchased the rights to manufacture and sell Sikorsky's larger [[Sikorsky H-19|Sikorsky S-55]] helicopter. While a Sikorsky-built pattern aircraft was flown by Westland in June 1951, converting the design to meet British standards (including the provision of a revised main-rotor gearbox), was time-consuming,<ref name="James Westland p320-1">James 1991, pp.320–321.</ref> and the first  prototype British aircraft, registered ''G-AMJT'', powered by the 600&nbsp;hp [[Pratt & Whitney R-1340|Pratt & Whitney R-1340-40 Wasp]] did not fly until August 1953.<ref name="James Westland p322">James 1991, p.322.</ref> This was followed by ten Whirlwind '''HAR.1'''s, which entered service shortly afterwards. They served in non-combat roles, including [[search and rescue]] and communications functions. The '''HAR.3''' had a larger 700&nbsp;hp [[Wright R-1300|Wright R-1300-3 Cyclone 7]] engine.

The performance of early versions was limited by the power of the American Wasp or Cyclone engines, and in 1955, the '''HAR.5''', powered by an uprated engine, the [[Alvis Leonides Major]], flew for the first time.<ref name="James Westland p329">James 1991, p.329.</ref> This was followed by the similarly powered '''HAS.7''', which became the first British helicopter designed for [[anti-submarine warfare]] in the front-line when it entered service in 1957. It could either be  equipped with a dipping [[Sonar]] for submarine detection or carry a torpedo, but could not carry both simultaneously, so sonar equipped "Hunters" were used to direct torpedo armed "Killers".<ref name="James Westland p330">James 1991, p.330.</ref> The HAS.7 was powered by a 750&nbsp;hp (560&nbsp;kW) Alvis Leonides Major 755/1 radial engine. It had a hovering ceiling at {{convert|9400|ft|m|abbr=on}} and a range of 334 miles at 86&nbsp;mph.

In 1960 Westland introduced a Whirlwind powered by the 1,000&nbsp;hp [[Rolls-Royce Gnome|Bristol Siddeley Gnome]] [[turboshaft]], the greater power giving much improved performance over the earlier piston-engined variants; helicopters receiving this modification were redesignated as the '''HAR.9'''. The Gnome featured an early computer controlled fuel system that removed variations in engine power and made for much easier handling by the pilot.

More than 400 Whirlwinds were built, of which nearly 100 were exported to foreign customers.<ref name="James West p336">James 1991, p. 336.</ref>

Some Whirlwinds were converted to turbine power and served well into the 1970s.<ref>{{Cite web |title=Westland Whirlwind HAR Mk.10 |url=https://helimuseum.com/heli.php?ident=whirlwind-mk10 |access-date=2024-03-17 |website=helimuseum.com}}</ref>

==Operational service==
[[File:Whirlwind helicopters on HMS Bulwark (R08) c1961.jpg|thumb|Whirlwind helicopters on a Royal Navy ship]]
[[848 Naval Air Squadron]] of the [[Royal Navy]]'s [[Fleet Air Arm]] was the first squadron to receive HAR.1s, which replaced Sikorsky-built HAR.21 versions of the Whirlwind, for utility and [[search-and-rescue]] service from July 1954. After entering service with the Royal Navy, the Whirlwind also entered service with the [[Royal Air Force]] and [[French Navy]],  which received 37 Whirlwind HAR.2 between 1954 and 1957.<ref name="James West p336">James 1991, p. 336.</ref>

The [[RAF Search and Rescue Force|Royal Air Force Air Sea Rescue Services]] used Whirlwinds painted in overall yellow for rescuing people in distress around the coast of the [[United Kingdom]]. [[Westland Wessex]], and eventually [[Westland Sea King]], helicopters later supplemented and eventually replaced Whirlwinds in this role.<ref>{{cite web|quote=It wasn't until 1955 that the Squadron reformed again, this time as a search and rescue unit equipped with Whirlwinds. It is in this guise that No. 22 Squadron exists today, having flown Wessex helicopters for a number of years before receiving Sea Kings in the mid-1990s.|url=http://www.raf.mod.uk/organisation/22squadron.cfm|title=RAF 22 Squadron|date=22 April 2017|access-date=8 March 2016|archive-url=https://web.archive.org/web/20161121103431/http://www.raf.mod.uk/organisation/22Squadron.cfm|archive-date=21 November 2016|url-status=dead|df=dmy-all}}</ref>

The last Whirlwind was retired from service in 1982, and the last HAR.10 in 1981.<ref>{{Cite web |title=Westland Whirlwind in united kingdom Royal Air Force |url=https://www.helis.com/database/modelorg/RAF-Whirlwind/}}</ref>

Two upgraded Whirlwinds (HCC.8 models) were added to the Queen's Flight in 1959, and eventually replaced by the Wessex helicopter.<ref>{{Cite web |date=2023-05-06 |title=The aircraft used to fly the Royal Family over the decades |url=https://www.key.aero/article/aircraft-used-fly-royal-family-over-decades |access-date=2024-03-17 |website=www.key.aero |language=en}}</ref>
