Hawker Siddeley

Hawker Siddeley, one of the largest and best-known companies in  British aviation, got its start through a bankruptcy. The failed firm,  Sopwith Aviation, had been very active during World War I and had built  the famous Sopwith Camel fighter plane. Orders from the government dried up following the end of  the war, in 1918, and Sopwith found itself struggling. Then the British  treasury presented a very large bill for excess profits during the war.  Unable to pay it, Sopwith responded by declaring that it was bankrupt.  Its assets were taken over by a group of investors led by the test  pilot Harry Hawker. His new firm, H. G. Hawker Engineering Company,  opened for business late in 1920.

Hawker found work initially by building motorcycles and motorcars  and by rebuilding used aircraft. However, company officials wanted to  return to being full-time planebuilders. The Royal Air Force was  placing orders for small numbers of new aircraft from a variety of  British companies, which gave Hawker Engineering its opportunity. A  brilliant chief designer, Sydney Camm, helped as well.

Under his leadership, Hawker scored a substantial success with a single-engine bomber, the Hart. Camm introduced a steel framework for light weight. The finished aircraft had an empty weight of only  2,530 pounds (1,148 kilograms), which gave it great speed. When the  first Harts entered service in 1930, they had a top speed of 184 miles  per hour (296 kilometers per hour), which was 30 miles per hour (48  kilometers per hour) faster than biplane fighters that tried to  intercept.

The Hart remained in production through much of the 1930s, and gave  rise to 17 variants. Because of its high speed, it was adapted for use  as a fighter. Another version, fitted with pontoons, flew with aircraft  carriers of the Royal Navy. More than 3,000 Harts were built, making  this the most produced British airplane in the years before World War  II.

Few other companies approached this success. Indeed, after 1930, the  Great Depression placed many planebuilders under considerable financial  stress. Officials of the British government responded by encouraging  aviation leaders to reorganize their industry into fewer but stronger  companies. Thomas Sopwith, chairman of Hawker, took the initiative by  drawing on profits from sales of Harts as he raised capital of £2  million, some $10 million. He then bought up other firms: Gloster  Aircraft, Armstrong Siddeley Motors, Armstrong Whitworth Aircraft, Air  Service Training, and A. V. Roe. In 1935 he reorganized these holdings  as the Hawker Siddeley Aircraft Company. These mergers placed those  firms on a good financial footing, at a time when war was only a few  years away.

Also during 1935, the rising threat of war with Germany led the  Under-Secretary of State for Air, Sir Philip Sassoon, to announce a  sharp increase in the purchase of warplanes. This change in policy took  place at a time when aircraft design was changing dramatically. The  best aircraft of the day, including the Hart, still were biplanes.  However, by the mid-1930s the all-metal monoplane was in the forefront. Such aircraft were heavier than biplanes, but excellent streamlining made them considerably faster. At Hawker, Sydney Camm soon was ready  with a new fighter: the Hurricane. It first flew in November 1935. In  April 1936, the directors of Hawker placed it into production even  before receiving a formal government order. It entered service in 1938  and showed a top speed of 325 miles per hour (523 kilometers per hour),  nearly twice that of the Hart.

Then in April 1940, the dictator of Germany, Adolf Hitler, unleashed  a powerful army that already had overrun Poland in less than a month.  The Netherlands now fell in only five days. France surrendered in June.  With complete victory in view, Hitler then ordered his generals to  prepare to invade England. Only one military command stood in their  way: the Royal Air Force.

The ensuing Battle of Britain succeeded in defending that nation, as  Hitler called off his invasion. The Hawker Hurricane emerged as the  outstanding fighter of this conflict. Hurricanes in service outnumbered  all other British fighters combined, shooting down 55 percent of all  enemy aircraft destroyed. The historian Francis Mason writes that the  Hurricane showed superior "ability to withstand battle damage, ease of  repair, better ability to operate from poor quality [airfields] and  comparative ease of flight training. It also proved much simpler to fly  at night."

The end of World War II led quickly to the Cold War, a prolonged  confrontation with the Soviet Union. Jet engines now were the key to  fighter design, and Sydney Camm took advantage of their power by  developing the Hawker Hunter fighter-bomber. During an early flight in  1953, its test pilot set a world speed record of 728 miles per hour  (1,172 kilometers per hour). Amid steady improvement, the Hunter was  crafted in 12 versions, with some 2,000 of these aircraft being built  by 1960. Faster fighters by then were available, but a Hunter could be  refueled and rearmed in as little as five minutes. It found a  particular role in attacking ground targets, for which it did not  require supersonic speed. It became popular in the export market, with hundreds of Hunters remaining in service into the 1980s.

Even so, it was clear by the mid-1950s that modern aircraft were too  costly for Britain to pursue on its own. Nor was there need for them;  American warplanes were the world's best and could easily be purchased.  In 1957 the British minister of defense, Duncan Sandys, issued a White  Paper, a formal document that announced a new policy: Great Britain  would build no new fighter aircraft for its Royal Air Force. The  industry was free to build airliners, sell fighters overseas, and  collaborate with the United States and with France. Even so, this  policy brought a sharp cutback in the prospects for Britain's  planebuilders.

They responded with a new wave of mergers. The engine-builders  Armstrong Siddeley and Bristol Aero-Engines combined in 1959 to form  Bristol Siddeley. Hawker Siddeley took over the big firm of De  Havilland Aircraft in 1960. Vickers, English Electric, and Bristol  Aircraft united to create British Aircraft Corporation, also in 1960. Rolls Royce, the nation's leading engine builder, merged with Bristol Siddeley in 1966.

At Hawker, innovation continued. Ralph Hooper, a senior manager, developed a strong interest in a new Bristol engine, the Pegasus, with nozzles that could swivel in any direction.  Hooper saw that a fighter powered by such an engine could direct its  thrust downward to take off and land vertically, to hover, to stop in  midair, and to maneuver in flight with unprecedented agility. He built  an experimental airplane, the P.1127, which first flew in 1960. This  led to an operational fighter, the Harrier. It showed such promise that  the British government reversed its White Paper policy and purchased  Harriers for both the Royal Navy and Royal Air Force, with the first of  them entering service in 1968. The U.S. Marines acquired their own  Harriers. In addition, Hawker Siddeley formed a partnership with  America's firm of McDonnell Douglas. This brought development of an advanced Harrier that could carry heavier loads.

The Harrier went to war in 1982, when Argentina seized the  British-held Falkland Islands in the South Atlantic. Prime Minister  Margaret Thatcher sent a naval force that included these fighters. They  shot down 28 Argentine aircraft while losing none of their own in  aerial combat. The British won the battle and took back the islands.

By then the firm of Hawker Siddeley no longer existed as such. An  act of Parliament in 1977 had combined it with British Aircraft to form  a single enormous company, British Aerospace. But old Thomas  Sopwith—Sir Thomas, having been knighted in 1953—was still very much  alive. He had been chairman first of Hawker and then of Hawker Siddeley  since 1920. He died in 1989 at the age of 100 years, as the last  pioneer from the early days of British aviation.
