'''Hawker Siddeley''' was a group of British manufacturing companies engaged in [[list of aircraft manufacturers|aircraft production]]. Hawker Siddeley combined the legacies of several British aircraft manufacturers, emerging through a series of [[mergers and acquisitions]] as one of only two such major British companies in the 1960s. In 1977, Hawker Siddeley became a founding component of the nationalised [[British Aerospace]] (BAe). Hawker Siddeley also operated in other industrial markets, such as [[locomotive]] building (through its ownership of [[Brush Traction]]) and [[diesel engine]] manufacture (through its ownership of [[Lister Petter]]). The company was once a constituent of the [[FTSE 100 Index]].

==History==

===Origins===
'''Hawker Siddeley Aircraft''' was formed in 1935 as a result of the purchase by [[Hawker Aircraft]] of the companies of [[John Siddeley, 1st Baron Kenilworth|J. D. Siddeley]], the automotive and engine builder [[Armstrong Siddeley]] and the aircraft manufacturer [[Armstrong Whitworth Aircraft]].<ref name=history>[http://www.centennialofflight.gov/essay/Aerospace/Hawker/Aero51a.htm US Centiennal of Flight Commission – Hawker Siddeley] {{webarchive|url=https://web.archive.org/web/20090825115531/http://centennialofflight.gov/essay/Aerospace/Hawker/Aero51a.htm |date=25 August 2009 }}</ref> At this time, Hawker Siddeley also acquired [[Avro|A.V. Roe & Company]] (Avro), [[Gloster Aircraft Company]] (Gloster) and Air Training Services.<ref name=history/> The constituent companies continued to produce their own aircraft designs under their own name as well as sharing manufacturing work throughout the group.

During the Second World War, Hawker Siddeley was one of the United Kingdom's most important aviation concerns, producing numerous designs including the famous [[Hawker Hurricane]] fighter plane that, along with the [[Supermarine Spitfire]], was Britain's front-line defence in the [[Battle of Britain]].<ref name=history/> During this campaign, Hurricanes outnumbered all other British fighters combined in service, and were responsible for shooting down 55 per cent of all enemy aircraft destroyed.

===Avro Canada===
In 1945, Hawker Siddeley purchased [[Victory Aircraft]] of [[Malton, Mississauga|Malton]], [[Ontario]], Canada from the [[Government of Canada|Canadian government]], renaming the company A.V. Roe Canada, commonly known as [[Avro Canada]], initially a wholly owned subsidiary of Hawker Siddeley.<ref name=arrow>{{Cite web |url=http://www.angelfire.com/psy/avro_arrow/ |title=The Avro Arrow – A Broken Dream |access-date=21 December 2008 |archive-date=6 August 2019 |archive-url=https://web.archive.org/web/20190806150340/http://www.angelfire.com/psy/avro_arrow/ |url-status=dead }}</ref> Avro Canada underwent a major expansion through aircraft development and acquisition of aircraft engine, mining, steel, railway rolling stock, computers, electronics, and other businesses to become, by 1958, Canada's third largest company directly employing over 14,000 people and providing 45% of the parent company's revenues.<ref>[http://www.universetoday.com/22747/book-review-cold-war-tech-war/ Whitcomb], p. 26</ref> During its operation, Avro Canada aircraft (built) included the [[Avro Canada C102 Jetliner|C102 Jetliner]], [[Avro Canada CF-100 Canuck|CF-100 Canuck]], [[Avro Canada CF-105 Arrow|CF-105 Arrow]] and [[Avro Canada VZ-9 Avrocar|VZ-9- AV Avrocar]]. Only the CF-100 fighter entered full-scale production.<ref name=arrow/> Other design projects (not built) included supersonic transport (SST) passenger aircraft, a mach-2 VTOL fighter, hovercraft, a jet engine-powered tank, and the hypersonic Space Threshold Vehicle.<ref>Whitcomb, pp. 10, 11, 236, 275.</ref> After the cancellation of the Arrow, the company began to unravel. In 1962, A.V. Roe Canada was dissolved and the remaining assets were transferred to the now defunct [[Hawker Siddeley Canada]].<ref name=arrow/>

===Postwar===
In 1948, the company name was changed to '''Hawker Siddeley Group'''. The aircraft division became '''Hawker Siddeley Aviation''' (HSA) and the [[guided missile]] and space technology operations as '''Hawker Siddeley Dynamics''' (HSD). In 1959, the [[aircraft engine|aero engine]] business, [[Armstrong Siddeley]] was merged with that of the [[Bristol Aeroplane Company|Bristol Aero Engines]] to form [[Bristol Siddeley]].<ref name=history/> In the late 1950s, the British government decided that with the decreasing number of aircraft contracts being offered, it was better to merge the existing companies, of which there were about 15 surviving at this point, into several much larger firms. Out of this decision, came the "order" that all future contracts being offered had to include agreements to merge companies. In 1959, [[Folland Aircraft]] was acquired, followed by [[de Havilland|de Havilland Aircraft Company]]<ref name=history/> and [[Blackburn Aircraft]] in 1960. In 1963, the names of the constituent companies were dropped, with products being rebranded as "''Hawker Siddeley''" or "''HS''". In this period, the company developed the first operational, and, by far, the most successful [[VTOL]] jet aircraft, the [[Hawker Siddeley Harrier|Harrier family]].<ref name=history/> This aircraft remained in production into the 1990s and remains in service.

====Hawker Siddeley Nuclear Power Company====
The Hawker Siddeley Nuclear Power Company built and operated the 10&nbsp;kW [[JASON reactor]]<ref>{{cite web |title=Hansard, Nuclear Reactors (Research And Training) Volume 631: debated on Monday 5 December 1960 |url=https://hansard.parliament.uk/Commons/1960-12-05/debates/151aa515-b608-43ee-a11e-2d2ef677ec35/NuclearReactors(ResearchAndTraining)}}</ref> in [[Langley, Berkshire]] (then in Buckinghamshire). The reactor was in operation there from 1959 to 1962 and generated a total of 1.4 MWh<ref>{{cite web |title=Transactions 11th International Topical Meeting Research Reactor Fuel Management (RRFM) and Meeting of the International Group on Reactor Research (IGORR) Centre de Congrès, Lyon, France 11–15 March 2007 |url=https://inis.iaea.org/collection/NCLCollectionStore/_Public/39/023/39023398.pdf?r=1}}</ref> before being shut down and transported to the [[Royal Naval College, Greenwich|Royal Naval College]] in [[Greenwich]], London.

====Kingston headquarters and factory====
In 1948, Hawker Siddeley acquired a factory in [[Kingston upon Thames]], [[Surrey]], on the [[A307 road|Richmond Road]] near [[Ham, London|Ham]]. This was to become their main aircraft factory and headquarters.<ref>{{cite web|url=http://myweb.tiscali.co.uk/hawkerassociation/hanewsletters/hanewsletter034nvu/greatrichmondrdfactory.html|title=The Great Richmond Road aircraft factory|publisher=Hawker Association|access-date=1 March 2018}}</ref>

====Expansion into railways====
In 1957, Hawker Siddeley purchased the Brush group of companies that included [[Brush Electrical Machines]], and [[Brush Traction]], which manufactures electromotive equipment and [[railway locomotive]]s.<ref>{{cite web|url=https://www.brush.eu/about-us/company-history|title=Company History {{!}} Brusk UK|website=The BRUSH Group|access-date=7 November 2018|archive-date=7 November 2018|archive-url=https://web.archive.org/web/20181107145113/https://www.brush.eu/about-us/company-history|url-status=dead}}</ref> The Brush prototype locomotives [[British Rail Class 53|''Falcon'']], and the futuristic but over-weight [[British Rail HS4000|HS4000 'Kestrel']], were produced there. Other railway engineering assets were acquired, including [[Westinghouse Rail Systems|Westinghouse Brake & Signal]]<ref>{{cite web|url=http://www.invensysrail.com/history.html|title=Invensys Rail: History|website=[[Invensys Rail Group]]|access-date=7 November 2018|url-status=dead|archive-url=https://web.archive.org/web/20081104054520/http://www.invensysrail.com/history.html|archive-date=4 November 2008}}</ref> and the engine builder [[Mirrlees Blackstone]], which came with the Brush businesses.<ref>{{cite web|url=http://www.enginemuseum.org/mrindex.html|title=Brief History and Development of Mirrlees Blackstone|website=[[Anson Engine Museum]]|access-date=21 December 2008|archive-date=18 November 2015|archive-url=https://web.archive.org/web/20151118185948/http://www.enginemuseum.org/mrindex.html|url-status=dead}}</ref>
[[File:CabooseSRM.jpg|thumb|left|[[Caboose]] built in the Hawker Siddeley plant of [[Thunder Bay]], Ontario]]
In the early 1970s, Hawker Siddeley's [[Canada Car and Foundry]] subsidiary began to build rapid transit vehicles for the North American market. The first order was for the [[Port Authority Trans-Hudson]] line and consisted of 46 PA-3 cars numbers 724–769, which were largely based on the original hexagonal profile PA-1 & PA-2 cars designed and built by the [[St. Louis Car Company]] during 1966–67. Hawker Siddeley later sold the same general design to the [[MBTA]] in Boston for their [[Blue Line (MBTA)|Blue]] and [[Orange Line (MBTA)|Orange Lines]]. 70 48' cars were delivered to the Blue Line in 1978–80 and 120 65' cars were delivered to the Orange Line in 1980–81. Hawker Siddeley also manufactured much of the [[Toronto subway|Toronto subway system's]] older [[Toronto subway and RT rolling stock|rolling stock]], the [[H series (Toronto subway)|H5 and H6 models]]. The heavy rail manufacturing business, based in [[Mississauga]] and [[Thunder Bay]], Ontario, are now part of [[Alstom]].

MBTA also bought a number of commuter rail coaches from the German firm [[Messerschmitt]], thereby teaming Hawker Siddeley with its old [[World War II]] rival under the same organisation.

===Nationalisation of aircraft production===
On 29 April 1977, as a result of the [[Aircraft and Shipbuilding Industries Act 1977]], Hawker Siddeley Aviation and Dynamics were nationalised and merged with [[British Aircraft Corporation]] (BAC) and [[Scottish Aviation]] to form [[British Aerospace]].<ref name=history/> However, HSA and HSD accounted for only 25% of the Hawker Siddeley business by this time, and the non-aviation and foreign interests were retained by a holding company known as ''Hawker Siddeley Group [[Public limited company|Plc]]'' after 1980.

===Rationalisation and sale to BTR===
The group rationalised in the 1980s, focusing on railway engineering and signalling, industrial electronics and instrumentation and signalling equipment.

[[Orenda Aerospace]], the only remaining original company from the Avro Canada / Hawker Siddeley Canada era, although greatly diminished in size and scope of operations, became part of the [[Magellan Aerospace|Magellan Aerospace Corporation]].<ref>{{Cite web |url=http://www.magellanroi.com/About_Us/hr_history/hr_history.html |title=Magellan Aerospace Corporation: History |access-date=21 December 2008 |archive-url=https://archive.today/20060515053758/http://www.magellanroi.com/About_Us/hr_history/hr_history.html |archive-date=15 May 2006 |url-status=dead }}</ref>

The late 1980s also saw Hawker Siddeley divest itself of much of its other North American heavy manufacturing enterprises. Its [[Talladega, Alabama|Talladega]], [[Alabama]]-based [[TreeFarmer]] heavy equipment business was sold to [[Franklin Equipment]] in 1990<ref>[http://www.franklin-treefarmer.com/company.htm Franklin: The realisation of the American Dream]</ref> and
its Canadian rail car production facilities were split between [[SNC-Lavalin]] and [[Bombardier Transportation|Bombardier]] in 1992.<ref>{{Cite web |url=http://www.caw.ca/en/4786.htm |title=CAW members ratify three-year agreement |access-date=21 December 2008 |archive-url=https://web.archive.org/web/20081212153939/http://www.caw.ca/en/4786.htm |archive-date=12 December 2008 |url-status=dead }}</ref>

In 1992, Hawker Siddeley Group Plc was acquired by [[BTR plc]] for £1.5bn. This was led by [[Alan Jackson (businessman)|Alan Jackson]] and [[Owen Green|Sir Owen Green]] who were the CEO and Chairman of BTR respectively during this time.<ref>[http://www.brushtraction.com/fhistory/history.htm Brush Traction: History]</ref> Through a series of takeovers, the business units finally became part of [[Schneider Electric]] in 2014.

===Hawker Siddeley name today===
In 1973, HS acquired the industrial electronics firm [[Hawker Siddeley Switchgear|South Wales Switchgear]]. Later known as Aberdare Holdings, in 1992 this company was renamed ''[[Hawker Siddeley Switchgear]]'' (HSS).<ref>{{Cite web |url=http://www.hss-ltd.com/about/history |title=HSS: History |access-date=21 December 2008 |archive-url=https://web.archive.org/web/20081205092359/http://www.hss-ltd.com/about/history |archive-date=5 December 2008 |url-status=dead }}</ref> They have an Australian subsidiary, ''Hawker Siddeley Switchgear Australia''. Another company which retains the name is ''Hawker Siddeley Power Transformers.''<ref>[http://www.businessmagnet.co.uk/company/hawkersiddeleypowertransformersltdincorporatingassociatedtapchangersfkitransformerdiv-55906.htm Hawker Siddeley Power Transformers]</ref>

In 1993, [[British Aerospace]] sold its corporate jet product line to the American [[Raytheon Company]]. In 2006 the product line was sold to a new company to be known as ''[[Hawker Beechcraft]]'', owned by [[Onex Partners]] and [[Goldman Sachs]].<ref>[http://www.boston.com/business/articles/2006/12/21/raytheon_to_sell_jet_subsidiary/ Raytheon to sell jet subsidiary]</ref>
