As a result, Billing sold his shares in the company for about £12,500 to Hubert Scott-Paine and the other directors who renamed the company Supermarine Aviation Works Ltd and officially registered it under that name on 27 June 1916. As well as Scott-Paine,

680-425: A lack of orders, 80 per cent of the staff were fired, leaving only 14 employees. On 14 November 1914 Broughton used his resources to pay off the company's debits which allowed the company to continue in business. Some work was obtained repairing aircraft subcontracting from Sopwith. Broughton then enlisted which left Scott-Paine in charge. At some point in 1914 Carol Vasilesco died suddenly of a heart attack, which left

816-508: A larger role, the new Spitfire caught the popular imagination and became the aircraft associated with the battle. It went on to play a major part in the remainder of the war, in a number of variants and marks, and it was the only Allied fighter aircraft to be in production through the entirety of the Second World War . Other company planes from the period include the Seafire (a naval version of

The resulting metal hulled version of the Southampton entered service as the Mk II. The Southampton series was very successful with a total of 83 of all types being built. As a result of the success of the Seagull and Southampton between 1923 and 1927 sales rose from £137,683 to £403,868 and profits from £58,002 to £111,935. While it had been Scott-Paine' love of speed and competitive nature that had been

1088-456: A monoplane seaplane called the S.4 which was used to set a new world air speed record over Southampton Water of 226.75 mph (364.9 kmh). However the sole example crashed during testing prior to the event, forcing the company to withdraw from the event. With sponsorship from the Air Ministry, Mitchell began to design a new streamlined monoplane aircraft designated the S.5 . Compared with

1224-619: A number of possible acquisitions. Blackburn Aircraft was in poor condition, Saunders was potentially too costly as a consortium headed by A.V. Roe was proposing to purchase them, while Short was too big and diverse. That left Supermarine. Aware that Supermarine's ability to modernise and expand was limited by a lack of financial resources, Bird and the other directors agreed to sell to Vickers in 1928. Vickers paid £390,000 and renamed it as Supermarine Aviation Works (Vickers) Ltd . Subsequently, in December 1938, following both Air Ministry's and

10064-789: The business was soon profitable, which allowed Billing (with the assistance of Scott-Paine) to design a series of flying boats with detachable propeller and wings so that with them removed it could be used as a motor launch. Pemberton-Billing submitted a patent application for his design in October 1913. After obtaining his aviator's certificate on 17 September 1913 following a £500 bet with Frederick Handley-Page that he could obtain it within 24 hour of commencing flight training, he decided to build his own aircraft.

In March 1938, Nationalist Chinese forces won their first major victory at Taierzhuang , but then the city of Xuzhou was taken by the Japanese in May. In June 1938, Chinese forces stalled the Japanese advance by flooding

10336-516: The commercial services Scott-Paine employed ex-RNAS pilots Henri Biard , Francis Bailey, Philip Brend. John Hoare, Basil Hobbs and Herbert Horsey. Following the completion of his duties for the Royal Naval Air Service NZAS James Bird (1883–1946) was invited in 1919 by Scott-Paine to join Supermarine as a director. A qualified marine architect he had previously been supervising contracts being undertaken by various companies in

10472-511: The company modified the Sea King II by increasing the size of the rudder and fin and fitting a more powerful engine which gave a 50 percent increase in power. Designated Sea Lion II the aircraft won the contest and thus stopped the Italians from winning the trophy outright. With it looking likely that no British company would be entering an aircraft in the 1923 Schneider Trophy contest Scott-Paine

10608-452: The company without a designer. In early 1915 the company obtained work building 12 Short S.38 seaplanes under licence. Work continued on the company's own designs with the next to see the light of day being the P.B.23. The prototype was delivered in September 1915 with tests conducted at Heldon indicating that the design had some promise. As a result, a revised version designated the P.B.25

10744-487: The company's technical capability Scott-Paine advertised for a personal assistant. The successful applicant was R. J. Mitchell , who so impressed Scott-Paine he was hired on the spot and given a range of roles within the company to expose him to every aspect of the business including within a year acted for a period as assistant works manager. In 1917 the company was contracted to build Short Type 184 torpedo bombers and Norman Thompson N.T.2B trainers. In response to

10880-494: The company, was; Supermarine, Southampton . The first aircraft built by the new company was the Pemberton-Billing P.B.1 a single-seat open cockpit biplane flying boat. Following modifications, the P.B.1 entered testing, but failed to achieve flight. Billing, who had designed the aircraft, claimed he "wanted a boat which would fly rather than an aircraft that would float". Though no proof can be found, Billing claimed that

11016-403: The conflict well into 1941. In December 1940, Roosevelt accused Hitler of planning world conquest and ruled out any negotiations as useless, calling for the United States to become an " arsenal of democracy " and promoting Lend-Lease programmes of military and humanitarian aid to support the British war effort; Lend-Lease was later extended to the other Allies, including the Soviet Union after it

11152-509: The contract was cancelled. For the next contest Mitchell created the all-metal S.6 which featured the smallest possible airframe that he could design around a Rolls-Royce engine instead of the Napier engines used in the S.4 and S.5. This design won the 1929 contest. For the 1931 contest Mitchell created the S.6a, a derivative of the S6. This won the contest and as Britain had won the trophy three times in

11288-515: The creation of a " New Roman Empire ". Adolf Hitler , after an unsuccessful attempt to overthrow the German government in 1923, eventually became the Chancellor of Germany in 1933 when Paul von Hindenburg and the Reichstag appointed him. Following Hindenburg's death in 1934, Hitler proclaimed himself Führer of Germany and abolished democracy, espousing a radical, racially motivated revision of

11424-739: The dissolution of the Austro-Hungarian, Ottoman, and Russian Empires. To prevent a future world war, the League of Nations was established in 1920 by the Paris Peace Conference . The organisation's primary goals were to prevent armed conflict through collective security, military, and naval disarmament , as well as settling international disputes through peaceful negotiations and arbitration. Despite strong pacifist sentiment after World War   I , irredentist and revanchist nationalism had emerged in several European states. These sentiments were especially marked in Germany because of

11560-405: The driving force behind the company's entry's in the early Schneider Trophy contests, Bird was happy to continue Supermarine's involvement as he wanted to use it to enhance the company profile. After the failure of their 1924 entry, and realizing that other countries designs were far superior, Mitchell reached the conclusion that racing flying boats were no longer competitive. As a result, he designed

11696-637: The end of May completed the German conquest of the Balkans. Partisan warfare subsequently broke out against the Axis occupation of Yugoslavia , which continued until the end of the war. In the Middle East in May, Commonwealth forces quashed an uprising in Iraq which had been supported by German aircraft from bases within Vichy-controlled Syria . Between June and July, British-led forces invaded and occupied

11832-460: The end of the war Supermarine was the only British aircraft constructor dedicated to building flying boats and Scott-Paine still wished the company to continue in this specialist field. To this end Supermarine joined the Society of British Aircraft Constructors in late 1919 and purchased from the government about 16 surplus AD Flying boats and the two completed Supermarine Babys. Supermarine modified 10 of

11968-508: The end of the war. World War II changed the political alignment and social structure of the world, and it set the foundation of international relations for the rest of the 20th century and into the 21st century. The United Nations was established to foster international cooperation and prevent conflicts, with the victorious great powers—China, France, the Soviet Union, the UK, and the US—becoming

12104-489: The existing Vickers aircraft manufacturing division which was restructured as a semi-independent subsidiary called Vickers (Aviation) Ltd under the management of Robert McLean . McLean was tasked with expanding the new company which he undertook by improving the capability of the existing factory and looking for new facilities. Identifying that a manufacturer of flying boats would be good fit with their existing expertise designing and constructing land-based aircraft they evaluated

12240-566: The first step of what its government saw as the country's right to rule Asia , staged the Mukden incident as a pretext to invade Manchuria and establish the puppet state of Manchukuo . China appealed to the League of Nations to stop the Japanese invasion of Manchuria. Japan withdrew from the League of Nations after being condemned for its incursion into Manchuria. The two nations then fought several battles, in Shanghai , Rehe and Hebei , until

12376-843: The former Chinese imperial capital of Peking after instigating the Marco Polo Bridge incident , which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a non-aggression pact with China to lend materiel support, effectively ending China's prior cooperation with Germany . From September to November, the Japanese attacked Taiyuan , engaged the Kuomintang Army around Xinkou , and fought Communist forces in Pingxingguan . Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai , but after three months of fighting, Shanghai fell. The Japanese continued to push Chinese forces back, capturing

12512-512: The invasion of the Ethiopian Empire (also known as Abyssinia ) by the armed forces of the Kingdom of Italy ( Regno d'Italia ), which was launched from Italian Somaliland and Eritrea . The war resulted in the military occupation of Ethiopia and its annexation into the newly created colony of Italian East Africa ( Africa Orientale Italiana , or AOI); in addition it exposed the weakness of

12648-483: The issue of Navy Air Board Specification N.1(b) in early 1917, the company designed what later was called the Supermarine Baby . Three were subsequently built. The signing of the armistice agreement, with little prospect of any military contracts for some time, led to the company diversifying by employing its woodworkers in constructing everything from toilet seats to wooden framed bodies for Ford Model T cars. At

12784-529: The main income between 1919 and 1921 came from selling Channels with a modified design known as the Channel II being developed. As well as sales within Great Britain the company was able to sell 19 overseas, to customers including Chile, Japan, New Zealand, Norway and Sweden. In 1919 Scott-Paine decided to enter an aircraft from Supermarine in the upcoming 1919 Schneider Trophy seaplane race. A suitable aircraft

12920-499: The market for small amphibians and flying boats which was becoming more competitive as Blackburn and Short Brothers entered the market, the company designed large multi-engine flying boats to Air Ministry specifications. As a result, one example was built of the Scylla , a torpedo bomber triplane flying boat to specification 14/21. No orders were forthcoming. One example was also built of the Swan ,

13056-448: The opinion that as well as wages being higher than at Vickers, it was also not being run efficiently, had poor record keeping, stock control, and was poorly equipped to build all-metal aircraft, with the ratio of unskilled to skilled labour at 1:3 compared with Vickers' 3:1. They therefore saw numerous opportunities to improve the profitability. One measure Vickers undertook was to send their experienced engineer Barnes Wallis to overhaul

13192-408: The other directors were Alfred Delves de Broughton and solicitor Charles Cecil Dominy. The first product of the new company was the P.B.31E Nighthawk which was a carryover from Billing's time for a quadruplane heavily armed and searchlight-equipped home defence fighter. Fitted with a recoilless Davis gun, it had a separate powerplant to power the searchlight . Only the prototype was built, which

13328-497: The permanent members of its security council . The Soviet Union and the United States emerged as rival superpowers , setting the stage for the Cold War . In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia . Most countries whose industries had been damaged moved towards economic recovery and expansion . World War II began in Europe on 1 September 1939 with

13464-571: The political European map with the defeat of the Central Powers —including Austria-Hungary , Germany , Bulgaria , and the Ottoman Empire —and the 1917 Bolshevik seizure of power in Russia , which led to the founding of the Soviet Union. Meanwhile, the victorious Allies of World War I , such as France, Belgium, Italy, Romania, and Greece, gained territory, and new nation-states were created out of

13600-583: The port of Tobruk . By late March 1941, Bulgaria and Yugoslavia signed the Tripartite Pact ; however, the Yugoslav government was overthrown two days later by pro-British nationalists. Germany and Italy responded with simultaneous invasions of both Yugoslavia and Greece , commencing on 6 April 1941; both nations were forced to surrender within the month. The airborne invasion of the Greek island of Crete at

13736-693: The remainder of Czechoslovakia and subsequently split it into the German Protectorate of Bohemia and Moravia and a pro-German client state , the Slovak Republic . Hitler also delivered an ultimatum to Lithuania on 20 March 1939, forcing the concession of the Klaipėda Region , formerly the German Memelland . Greatly alarmed and with Hitler making further demands on the Free City of Danzig ,

14008-410: The significant territorial, colonial, and financial losses imposed by the Treaty of Versailles . Under the treaty, Germany lost around 13 percent of its home territory and all its overseas possessions , while German annexation of other states was prohibited, reparations were imposed, and limits were placed on the size and capability of the country's armed forces . The German Empire was dissolved in

14144-494: The start or prelude to World War II. The exact date of the war's end also is not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 15 August 1945 ( V-J Day ), rather than with the formal surrender of Japan on 2 September 1945, which officially ended the war in Asia . A peace treaty between Japan and the Allies was signed in 1951. A 1990 treaty regarding Germany's future allowed

14280-461: The strength and profitability of the group. The most notable was their merger in January 1928 with long term rival Armstrong Whitworth to form Vickers-Armstrongs , with the exception of the Armstrong-Whitworth aircraft division and Armstrong Siddeley motor car division, which were bought out by J. D. Siddeley , and so did not join the new group. The new Vickers-Armstrong entity retained

14416-575: The strong Maginot Line fortifications on the Franco-German border, Germany directed its attack at the neutral nations of Belgium , the Netherlands , and Luxembourg . The Germans carried out a flanking manoeuvre through the Ardennes region, which was mistakenly perceived by the Allies as an impenetrable natural barrier against armoured vehicles. By successfully implementing new Blitzkrieg tactics,

14552-569: The two wars became World War II in 1941. Other proposed starting dates for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War   II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939. Others view the Spanish Civil War as

14688-504: The war were not fulfilled in the peace settlement. From 1922 to 1925, the Fascist movement led by Benito Mussolini seized power in Italy with a nationalist, totalitarian , and class collaborationist agenda that abolished representative democracy, repressed socialist, left-wing, and liberal forces, and pursued an aggressive expansionist foreign policy aimed at making Italy a world power, promising

14824-553: The war, the company produced a series of jet fighters . The company was founded in 1913 as Pemberton-Billing Ltd on the River Itchen close to Woolston, Southampton , on ground previously purchased by Noel Pemberton Billing to construct motor launches. It produced a couple of prototypes using quadruplane designs to shoot down zeppelins , the Supermarine P.B.29 and the Supermarine Nighthawk . The aircraft were fitted with

14960-475: The war. Germany annexed western Poland and occupied central Poland ; the Soviet Union annexed eastern Poland ; small shares of Polish territory were transferred to Lithuania and Slovakia . On 6 October, Hitler made a public peace overture to the United Kingdom and France but said that the future of Poland was to be determined exclusively by Germany and the Soviet Union. The proposal was rejected and Hitler ordered an immediate offensive against France, which

15096-477: The water, which were eventually resolved. This led to 34 being built, though none saw service. In March 1916 Billing was elected as an MP . Once in parliament he was very vocal in his support of air power, constantly accusing the government of neglecting the issue. As he intended to run a campaign against the Royal Aircraft Factory and its products, it became apparent that if the company was to maintain

15232-503: The west halted the German advance for several days, but it was outflanked and encircled by the Wehrmacht . Remnants of the Polish army broke through to besieged Warsaw . On 17 September 1939, two days after signing a cease-fire with Japan , the Soviet Union invaded Poland under the supposed pretext that the Polish state had ceased to exist. On 27 September, the Warsaw garrison surrendered to

15368-550: The wings and undertake the final completion of two Vickers Viastra airliners and then employing it to construct a special version called the Viastra X, for the Prince of Wales . The other notable work was the design of the Type 179 , a six-engined flying boat, which led to the company being awarded a contract to build a prototype. Construction proceeded as far as the construction of the hull before

15504-626: The work practices in the design department. He arrived while Mitchell was away on his 1929 Christmas holidays and after installing himself in Mitchell's office began to make changes. Mitchell returned in the New Year, expressed his outrage at Wallis's presumption and immediately moved him to a disused loft in a remote corner of the Woolston works with orders to his staff not to make the interloper comfortable. Wallis eventually complained to McLean, who raised it with

15640-687: The world order , and soon began a massive rearmament campaign . France, seeking to secure its alliance with Italy, allowed Italy a free hand in Ethiopia , which Italy desired as a colonial possession. The situation was aggravated in early 1935 when the Territory of the Saar Basin was legally reunited with Germany, and Hitler repudiated the Treaty of Versailles, accelerated his rearmament programme, and introduced conscription. The United Kingdom, France and Italy formed

15776-614: Was invaded by Germany. The United States started strategic planning to prepare for a full-scale offensive against Germany. At the end of September 1940, the Tripartite Pact formally united Japan, Italy, and Germany as the Axis powers . The Tripartite Pact stipulated that any country—with the exception of the Soviet Union—that attacked any Axis Power would be forced to go to war against all three. The Axis expanded in November 1940 when Hungary , Slovakia , and Romania joined. Romania and Hungary later made major contributions to

15912-560: Was able together with Southern Rail and the Asiatic Petroleum to establish the British Marine Air Navigation Company in 1923. They subsequently ordered three Sea Kings, which were used to commence a daily service on 25 September 1923 between Southampton and Guernsey. Then late in 1922 orders were received from the Air Ministry for five Seagull IIs followed by two further orders in early 1923. Later orders for what

16048-451: Was applied to the aircraft. Despite selling his shares to Vickers-Armstrongs, Bird stayed on as managing director of Supermarine while Mitchell continued as chief designer. He had signed a 10-year employment contract in 1923, that included a clause that said, if he left Supermarine he could not work for any other competitor without the directors written consent. While Supermarine was extremely profitable McLean and his management team were of

16184-591: Was applied to the aircraft. The first Supermarine landplane design to go into production was the famous and successful Spitfire . The earlier Hawker Hurricane and the Spitfire were the mainstay of RAF Fighter Command fighter aircraft which fought off the Luftwaffe bombing raids with fighter escorts during the Battle of Britain in the summer of 1940. While the Hurricane was available in larger numbers and consequently played

16320-597: Was called the Seagull III were received in 1925 from the Royal Australian Navy. Partly due to Scott-Paine's preoccupation with developing the airline business the relationship between him and Bird began to breakdown. As a result, Bird assembled sufficient funds and on 16 November 1923 he confronted Scott-Paine who after negotiation accepted Bird's offer of £192,000 of his shares and left the company. In 1925 in an attempt to obtain additional funds with which to expand

16456-454: Was expected would place an order for aircraft with Supermarine. In expectation of receiving an order the directors decided not to reduce staff numbers. Meanwhile, to meet the requirements of the expected order Mitchell designed the Sea King in late 1922 to carry six passengers in an enclosed cabin. After receiving confirmation that subsidies would be available from the British government Scott-Paine

16592-573: Was felt that production was not worth pursuing. With no orders coming in, Billing had to sell one of his yachts and lease out part of the facilities to Tom Sopwith who used it for assembly and then testing of his Bat Boat . At the outbreak the First World War Billing enlisted in the Royal Navy Volunteer reserve, and thus he was no longer involved in day-to-day activities. With the business by now in serious financial trouble due to

16728-464: Was finished Supermarine received an order in late 1926 for two examples, with an order for a third following in early 1927. The S.5 dominated the 1927 contest, finishing first and second. The third example crashed killing its pilot while he was attempting to set a new air speed record over the Solent in 1928. In the late 1920s Vickers Ltd began a series of divestments and mergers as it attempted to improve

16864-563: Was found to have insufficient performance to be of any use against Zeppelins. After completion of the Nighthawk Scott-Paine dropped Billing's fixation with anti-Zeppelin defence fighters, and in the hope of gaining orders for flying boats forged a strong relationship with the RNAS through their local liaison officer James Bird. In early 1916 William Abraham Hargreaves was hired as chief designer. By 1917 realizing that he needed to strengthen

17000-493: Was hoped that he would be more diplomatic in bringing Supermarine's design office into agreement with Vickers work practices. That said the parent company provided the combined Vickers (Aviation) Ltd with £250,000 in 1929 to support research and development. As a consequence the capabilities of the design team at Supermarine were expanded by employing among others Alfred Faddy, William Munro (who had expertise in hydrodynamics and metal hull construction) and Beverley Shenstone who

17136-467: Was in electrical engineering and automobiles. Romanian Carol Vasilesco was employed to prepare drawings and undertake the detailed design of airframes. On land at Oakbank Wharf on the river Itchen in Woolston, Southampton that Billing had previously purchased, the company established a factory with Hubert Scott-Paine as work manager. Its registered telegraphic address , used for sending telegrams and cables to

17272-505: Was insufficient time to overcome a number of design issues which lead to Supermarine withdrawing from the event. In the early 1920s the company developed a series of similar one-off amphibians. The most notable of these was the Seal II, which was a three-seater fleet spotter paid for by the Air Ministry. After it performed well during its evaluation by the RAF, two examples of an improved version, named

17408-524: Was persuaded by the British organizers to enter. As Supermarine being in a poor financial state, Mitchell was restricted to modifying the Sea Lion II, the result which was designated Sea Lion III and proved to be uncompetitive. For the 1924 contest Mitchell began design work on a completely new flying-boat biplane design called the Sea Urchin, which would have been fitted with a Rolls-Royce engine. However, there

17544-452: Was postponed until the spring of 1940 due to bad weather. After the outbreak of war in Poland, Stalin threatened Estonia , Latvia , and Lithuania with military invasion, forcing the three Baltic countries to sign pacts allowing the creation of Soviet military bases in these countries; in October 1939, significant Soviet military contingents were moved there. Finland refused to sign

17680-474: Was produced by heavily modifying N61, the youngest of the two Babys that the company had purchased from the government. Fitted with a Napier Lion engine it was given the name Sea Lion . Flown by Basil Hobbs the aircraft sank on 10 September 1919 after it struck flotsam while competing in the event. In early 1920 the company developed the Supermarine Sea King a single seat flying boat fighter resembling

17816-587: Was produced, for which an order for 20 was received from the Royal Naval Air Service . In late 1915 having completed serving with the RNVR and RNAS Billing returned to the company. As a result of his experience while involved in the organising of the air raid in November 1914 on the Zeppelin sheds at Friedrichshafen on Lake Constance Billing believed that England was defenceless against attacks by Zeppelins. As

17952-511: Was promoted within the Vickers group and left Supermarine. He was succeeded at Supermarine by H.B. Pratt. In response to the onset of the Depression in 1929, with completion of contracts for Southampton running down and no new aircraft orders being received it was necessary to reduce construction staff numbers by a third over the winter of 1930. Vickers supported Supermarine by contracting it to build

18088-761: Was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with

18224-651: Was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless. The United States, concerned with events in Europe and Asia, passed the Neutrality Act in August of the same year. Hitler defied the Versailles and Locarno Treaties by remilitarising the Rhineland in March 1936, encountering little opposition due to the policy of appeasement . In October 1936, Germany and Italy formed

18360-480: Was the deadliest conflict in history, resulting in 70 to 85 million deaths , more than half being civilians. Millions died in genocides , including the Holocaust of European Jews, as well as from massacres, starvation, and disease. Following the Allied powers' victory, Germany , Austria , Japan , and Korea were occupied, and war crimes tribunals were conducted against German and Japanese leaders . The causes of World War II included unresolved tensions in

18496-504: Was the first academically trained aerodynamicist at Supermarine. As a consequence the services of Mitchell's deputy Frank Holroyd were no longer required and he was dismissed. By 1931 the restructuring of the company ended with Mitchell still technical director and reporting to him, the Technical Office under Alan Clifton and the Drawing Office under Joe Smith. Vickers' own pilots took over test flying, which led to Henry Biard's role as Supermarine's test pilot since 1919 coming to an end. As
