On November 11th the indefatigable David Hassard, who has given more
than 200 talks on Sopwith, Hawker and other local firms, addressed the
Association on the importance of Kingston’s aircraft industry to the
war effort. David tackled the story chronologically talking to
excellent slides. Such a talk is difficult to report as it is so visual
and packed with improvised verbal detail. What follows can give but a
poor impression of the actual event.
In 1906-07 the Brooklands motor racing circuit was built near
Weybridge. Inside the banked concrete oval was a large, flat and level
expanse of grass which was soon used as an aerodrome by the aviation
fraternity. Tommy Sopwith taught himself to fly there in 1910. Many
manufacturers and flying schools set up their ‘sheds’ at Brooklands,
including Sopwith in 1912. He would teach you to fly for £75 (£7,500
today). His engineer, Fred Sigrist, created the Sopwith Hybrid as an
improved trainer which was sold to the Admiralty causing the Sopwith
Aviation Co, a family owned business, to be accredited.
With Vickers, Bristol and other companies there
Brooklands became crowded so Sopwith rented the Kingston roller skating
rink with its level and flat open space (no pillars), ideal for
building aircraft. A supply of skilled boatbuilding woodworkers was
available locally and there were plenty of women workers with fabric
cutting and stitching skills. Aircraft were taken by road to fly from
Brooklands.
The first product of the Kingston factory was the flying
boat/amphibian Bat Boat which set many records in the hands of
Australian Harry Hawker, who had joined Sopwith and Sigrist as a
mechanic but was taught to fly by Sopwith and became the Company’s test
and demonstration pilot and co-designer.
In 1913 aircraft production was under way with sales
to both the Navy and the Army of float and landplanes. The small, 80
hp, two seat Sopwith Tabloid, brainchild of Hawker and tested at
Farnborough, demonstrated a maximum level speed of 92 mph, the fastest
ever recorded. It was soon ordered for the Army’s Royal Flying Corps
(RFC). In December 1913 the Sopwith Aviation Company Ltd was formed and
started its expansion in Canbury Park Road, Kingston.
The speaker went through every Sopwith, and other
manufacturer’s, types on a year-by-year basis, illustrating each with
excellent photographs, and highlighting particular design features and
achievements. The Tabloid proved to be a very important type which set
the pattern for all subsequent fighting scouts. It was developed into
the Baby and led to the Pup, Triplane, Camel, Snipe and Dragon.
In April 1914 a Taboid floatplane won the
international Schneider Trophy race at Monaco and set the world speed
record. During 1914 production increased; 12 Sopwith Folders, 24
Spinning Jennies and 18 torpedo droppers were sold to the Royal Naval
Air Service (RNAS).
In 1915 130 Sopwith Schneider floatplanes, derived
from the Monaco Tabloid, were ordered and 30 Sopwith pusher landplanes
were subcontracted to Robey & Co. Other manufacturers operating in
Surrey included Bleriot and DFW at Brooklands from 1914. In 1915 Martin
and Handasyde/Martinsyde at Woking and Brooklands, Whitehead Aircraft
at Richmond and Vickers of Crayford, Kent who had bought the Itala car
works at Brooklands, were all active in Surrey.
Sigrist’s 1 ½ Strutter with its synchronised forward
firing machine gun emerged in early 1915 followed by the Pup in 1916.
58 fighter and 178 bomber Strutters were ordered from Sopwith.
Contractors would build 1100 and 4200 would be built in France. 97 Pups
were ordered from Sopwith with 250 from contractors.
The high performance Sopwith Triplane, based on the
Pup fuselage, flew in 1916; Sopwith built 103, Contractors 49. That
year Whitehead built 100 Pups. The Sopwith Camel flew in 1917 and was
ordered for the RFC and the RNAS. 553 were built by Sopwith and ten
Contractors built 5194. By the end of 1917 the Canbury Park factory
covered 5½ acres and was soon building the four gun Dolphin of which
1000 had been ordered from Sopwith with 750 from Contractors.
Because of the high attrition rate with an aircraft
average life of 8 weeks, the Government needed 3500 new aircraft every
month to support the 200 squadrons required for air superiority. To
satisfy this the Government instituted the National Aircraft Factory
(NAF) scheme; four were to have been built. NAF 2 was built at Ham and
leased by Sopwith to build 700 Snipes, 800 Salamanders and 330 Dragons.
In September 1918 Sopwith was building 40 aircraft a week. Whitehead,
Bleriot, Martinsyde, Vickers and Glendower at Kew were also mass
producing military aircraft under contract. In 1918-19 6000 aircraft
were built in Surrey.
The armistice was signed on November 11th 1918 leading to the
cancellation of orders and a consequent 60% cut in the workforce.
During WW I 18100 aircraft had been built to Sopwith designs.
After the war Sopwith struggled to keep going with
some prototype aircraft and motorcycle manufacture but had to close
down when the Government submitted a bill for excess profit tax. The
Sopwith Aviation Co Ltd was liquidated and a new era started in 1920
when, Sopwith, Sigrist and Hawker started again with the HG Hawker
Engineering Co which grew into Hawker Aircraft and the industrial
giant, Hawker Siddeley.
David Hassard produces a weekly article, ‘The
Kingston Aviation Story - 100 Years Ago This Week’, which you can find
on-line at www.kingstonaviation.org. David started this important task
in May 2013 and is now approaching his 300th issue. Deeply researched
and precisely illustrated the articles chronicle, week-by-week, the
progress of TOM Sopwith, his companies, his colleagues, his aircraft
and their achievements. All back issues are available.
