Wight built Aircraft

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.

The 1932 ZK-ARH Spartan is still airworthy and currently in New Zealand. Owner Rod Hall Zones has lovingly restored the aircraft and kept it flight worthy.

Rob would like the aircraft to become part of the Wight Aviation Museums collection and we hope to secure enough funding in future to achieve this.

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 only surviving SRA/1 Prototype TG263, is currently on display at the Solent Sky Museum in Southampton. The two other prototypes we’re lost in accidents during flight testing.

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.

Britten Norman Islander

The Britten-Norman BN-2 Islander is a British light utility aircraft and regional airliner designed and originally manufactured by Britten-Norman from the mid 1960’s.

It Still in production today and the Islander is one of the best-selling commercial aircraft types produced in Europe, with over 750 still in service with commercial operators around the world. The aircraft is also used by the British Army and police forces in the United Kingdom and is a light transport with over 30 military aviation operators around the world.

Initially the aircraft were manufactured at Britten-Norman’s factory in Bembridge, Isle of Wight, UK but due to increased demand additional capacity was added in Romania, but after the company ran into cash flow problems in the early 1970’s the company was acquired by Fairey Aviation and production of the Islanders and it’s larger sibling the Trislander aircraft, was only continued in Romania to reduce production costs.

The completed fuselages were then shipped to Avions Fairey works in Belgium for finishing, before being flown to the UK for flight certification. The Islander has now been in production for over 50 years.

How it started:

In 1953 Britten-Norman was formed by John Britten and Desmond Norman for the purpose of converting and operating agricultural aircraft, amongst other vehicles such as the Cushioncraft hovercraft. In 1963, the firm initiated development work upon what would become the Islander, having sensed a demand for a simple and inexpensive twin-piston engine aircraft. John and Desmond had seen the rapid growth of the commuter airline sector and concluded that capacity was of a higher value to these operators than either range or cruising speed, thus the Islander emphasized payload over either of these attributes.

This plywood prototype gives a good idea of the compact size of the Aircrafts cabin.

The Islander could lift considerably heavier payloads than the typical aircraft in its power, weight or cost classes. To reduce manufacturing costs, both the wings and tail surfaces maintain a constant profile and thickness, while the ribs within the aircraft’s wing are all identical; both rivets and external fishplate joints are used for the same purpose. The type was originally intended to use a fabric-and-steel design. A light alloy monocoque approach was adopted instead. The structure is designed to give rise to and experience low levels of stress, and has an infinite fatigue life without testing.

The prototype BN-2 Islander displayed at the 1965 Paris Air Show six days after its maiden flight
On 13 June 1965, the first prototype BN-2 Islander conducted its maiden flight, powered by a pair of Rolls-Royce/Continental IO-360B piston engines; only four days later, the prototype appeared at the Paris Air Show. The IO-360B engines were later replaced by more powerful Lycoming O-540-E engines, which were located further outboard on the wings, for superior single-engine climb performance. On 20 August 1966, a second BN-2 prototype performed its first flight. These prototype aircraft, while resembling subsequent production models for the most part, were outfitted with different, less powerful engines. On 24 April 1967, the first production Islander performed its first flight; UK type certification was received in August 1967, US authorities also certified the type in December 1967.

Initial production of the Islander started at the Britten-Norman factory at Bembridge on the Isle of Wight; however, within a few years the company found that it could not produce the aircraft at a sufficient rate to keep up with the customer demand. To expand production, a contract was placed with Intreprinderea de Reparatii Material Aeronautic (IRMA) of Romania, initially to assemble kit-form aircraft, which were then sent to the UK for completion. In August 1969, the first Romanian-assembled Islander performed its first flight. IRMA proved successful at economically producing the aircraft, producing roughly 30-40 aircraft per year at times, and eventually became the primary manufacturing site for the Islander. In 1977, IRMA received a contract for the production of a further 100 Islanders; from that point on, the firm produced all subsequent Islander aircraft. More than 500 of the type were manufactured in Romania

The popularity of the Islander led to a model kit being produced by Valom.

In 1970, a military version of the Islander, marketed as the Defender, conducted its first flight. Modifications included the addition of underwing hardpoints for armaments/equipment, and the main cabin area being fitted out for light troop transport and support aircraft duties. The Defender capitalised on the aircraft’s rugged structure, making it suitable for long-term operations in developing countries. Purchases from police and military customers have typically been for use in surveillance and counter-terrorism operations. The Maritime Defender is another military version of the Islander, intended for search and rescue, coastal patrol and fishery protection.


The Britten-Norman BN-2 Islander is a high-wing cantilever monoplane with a rectangular fuselage and two wing-mounted engines; early aircraft were equipped with a pair of piston engines while later production models may be alternatively fitted with turboprop engines in their place. The rectangular cross section fuselage, which is furnished with a conventional tail unit and fixed tricycle landing gear, typically accommodates a single pilot and up to nine passengers in a commuter configuration, each row being accessed by its own door; the cabin can be rapidly reconfigured, allowing for a single aircraft to undertake a diverse range of tasks within a minimal period of time. Often referring to the type as “The world’s most versatile aircraft”, Britten-Norman promotes the Islander’s low direct operating costs, minimal maintenance, and its stability in flight as major attributes of the aircraft.

The original Islander was designed with an emphasis upon providing ease of access within the short haul sector to remote locations as a safe, efficient, and profitable transport aircraft. It has been regularly used by such operators, including the frequent use of unprepared rough airstrips and from challenging terrain; the Islander being capable of short takeoff and landing (STOL) operations. The low load height and wide side doors provide for easy access for passenger and cargo operations, while the aircraft’s ability to maintain a high takeoff frequency has led to the type’s use for parachuting. For operating within noise-sensitive environments, silencers can be equipped on both the aircraft’s engine and propellers.

Designed as a small and inexpensive commuter/utility aircraft, various cabin configurations and equipment loadouts are available to suit a wide variety of different purposes, including charter flights, scheduled flights, agricultural uses, aerial firefighting, air freight VIP/executive transport, aerial surveillance, air ambulance, paradropping, and law enforcement.

The design programme can be entirely personalized, allowing each customer to be involved in every area of the aircraft’s manufacture to mold it to their preferences. Later versions of the Islander offer various options, including enlarged bay doors, 3-bladed scimitar propellers, low drag fairings, modern interior, ergonomic leather seating, in-flight entertainment systems, and alternative seat arrangements; underwing hardpoints can also be installed for carrying pod, spray booms and other external stores.
