, a well-to-do gentleman sportsman interested in aviation, yachting and motor-racing, in June 1912, when Sopwith was only 24 years old. The company's first factory premises opened that December in a recently closed roller skating rink in Canbury Park Road near Kingston Railway Station in South West London. An early collaboration with the S. E. Saunders boatyard of East Cowes on the Isle of Wight, in 1913, produced the Sopwith "Bat Boat", an early Flying boat
Flying boat
A flying boat is a fixed-winged seaplane with a hull, allowing it to land on water. It differs from a float plane as it uses a purpose-designed fuselage which can float, granting the aircraft buoyancy. Flying boats may be stabilized by under-wing floats or by wing-like projections from the fuselage...

During the First World War, the company made more than 16,000 aircraft and employed 5,000 people. Many more of the company's aircraft were made by subcontractors rather than by Sopwiths themselves. These included Fairey

After the war, the company attempted to produce aircraft for the civil market based on their wartime types, such as the Dove derivative of the Pup and the Swallow, a single-winged Camel, but the wide availability of war-surplus aircraft at knock-down prices meant this was never economic. In 1919 the company worked with ABC motorcycles

Famous Sopwith aircraft


Initially, Tom Sopwith himself, assisted by his former personal mechanic Fred Sigrist, led the design of the company's types. Following a number of unremarkable pre-war designs for the Royal Naval Air Service, such as the Three-Seater and Bat-Boat, Sopwith's first major success was the fast and compact (hence the name) Tabloid

 fighter was introduced. This aircraft was highly manoeuvrable and well-armed, and over 5,000 were produced up until the end of the War. It destroyed more enemy aircraft than any other British type, but its difficult flying qualities also killed very many novice pilots in accidents. It was used, modified, as both a night-fighter and shipboard aircraft, and was flown in combat by the Belgian and American Air Services as well as the British.

 armoured ground-attack development of the Snipe, but these types were too late to see action. Many other experimental prototypes were produced throughout the war, mostly named after animals (Hippo, Gnu etc.), leading to some referring to the 'Sopwith Zoo'.

Following World War I, the Sopwith Snipe was chosen as the standard fighter of the much-reduced Royal Air Force, and soldiered on until finally replaced in the late 1920s.
