Some of the incredible Aircraft built on the Isle of Wight over the last 120 years..
The Simmonds Spartan – 1930’s
The Simmond Spartan bi-plane was designed and built in Somerton, Cowes in the early 1930’s. These 3 seater planes were extremely popular with the new generation of wealthy private pilots, allowing 2 passengers to be flown hundreds of miles for business and pleasure, all be it exposed to the elements.
The wings were designed to fold back easily, in order to be stored in a shed rather than requiring a dedicated hangar, 25 of the 3 seater Spartans were produced in total in the early 1930’s.

Saunders-Roe SR.A/1 – 1940’s
The Saunders-Roe SR./A.1 was a prototype flying boat fighter aircraft designed and built by British seaplane manufacturer Saunders-Roe. It was the first jet-propelled water-based aircraft in the world.
The concept behind the SR./A.1 originated during the Second World War as a reaction to Japan’s successful use of military floatplanes and the emergence of the turbojet engine. Saunders-Roe presented an initial proposal of their jet-powered seaplane concept, then designated SR.44, to the Air Ministry during mid-1943.
In April 1944, the Ministry issued Specification E.6/44 for the type and supported its development with a contract for three prototypes. Development was protracted by Saunders-Roes’ work on other projects, the war having ended prior to any of the prototypes being completed.
On 16 July 1947, the first prototype made its maiden flight. The SR./A.1 was evaluated by the Royal Air Force (RAF), who concluded that the design was incapable of matching up to the performance of land-based designs. Despite interest from foreign governments, including the United States, no orders for the SR./A.1 materialised.
As such, it never entered volume production or saw service with any operators. While interest in the SR./A.1 programme was briefly revived following the start of the Korean War, the aircraft was considered to be obsolete by that point and was again rejected.

The SR-53 Jet Fighter – 1950’s
The SR-53 Jet Fighter was designed and built by Saunders Roe at the famous Columbine Works in East Cowes.
The Saunders-Roe SR.53 was a British prototype interceptor aircraft of mixed jet and rocket propulsion developed for the Royal Air Force (RAF) by Saunders-Roe in the early 1950s.
The SR.53 would have been used as an interceptor aircraft, using its rocket propulsion to rapidly climb and approach incoming hostile bombers at high speeds and following it’s attack run, the aircraft would be able to return to its base by making use of the secondary jet propulsion instead.
Although the SR.53 proved to have promising performance during test flights, the requirement for such an aircraft had been overtaken by rapid advances in surface-to-air missile technology, leading to reconsideration of the aircraft’s purpose. In July 1960, the development program was formally cancelled, by which time a total of 56 test flights had been performed.
A pair of prototype SR.53 aircraft had been completed and used during flight tests. One of these was destroyed during one such test flight in June 1958. The other, the first prototype, survived and was preserved and is currently on public display at the Royal Air Force Museum Cosford.
