Saunders-Roe PrincessThe Saunders-Roe SR.45 Princess was a British flying boat aircraft developed and built by Saunders-Roe at their Cowes facility on the Isle of Wight. It is the largest all-metal flying boat to have ever been constructed. The Princess had been developed to serve as a larger and more luxurious successor to the prewar commercial flying boats, such as the Short Empire. It was intended to serve the transatlantic route, carrying up to 100 passengers between Southampton, United Kingdom and New York City, United States, in spacious and comfortable conditions. To achieve this, designers decided early on to make use of newly developed turboprop technology, opting for the Bristol Proteus engine still in development to power the aircraft. The project suffered delays due to difficulties encountered in the development of the Proteus engine. On 22 August 1952, the first prototype Princess, G-ALUN, conducted its maiden flight. Between 1952 and 1954, the first prototype performed a total of 47 test flights, including two public appearances at the Farnborough Airshow. This work was carried out under a development contract for the Ministry of Supply, the intention being that this would lead to a contract for the aircraft from British flag carrier British Overseas Airways Corporation (BOAC). Although the initial development contract had been successfully met, BOAC eventually decided to focus on its land-based routes using the jet-powered De Havilland Comet, instead. The era of the large flying boat had effectively ended prior to the aircraft's completion. Work on the Princess was ultimately cancelled after having produced three examples, only one of which flew. By the mid-1950s, large commercial flying boats were being increasingly overshadowed by land-based jet airliners. Factors such as runway and airport improvements had added to the viability of land-based aircraft, which did not have to compromise to accommodate the additional weight and drag of the boat hulls that were necessary on seaplanes, or the mitigating measures needed against the corrosion caused by seawater. Following the project's termination, the three airframes were stored with the intention of selling them on, but upon receipt of a promising offer for the aircraft, corrosion was found to have set in while in storage. As a result, all three aircraft prototypes were subsequently scrapped.

Saunders-Roe SR.A/1The 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-Roe's 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.

Saunders-Roe SR.53The 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. As envisaged, 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; following its attack run, the aircraft would then return to its base using jet propulsion. 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 programme 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. The second prototype was destroyed during one such test flight in June 1958. The first prototype has been preserved to this day. It rests on public display at the Royal Air Force Museum Cosford.

Saunders-Roe SR.177The Saunders-Roe SR.177 was a 1950s project to develop a combined jet- and rocket-powered interceptor aircraft for the Royal Air Force (RAF) and Royal Navy. It was an enlarged derivative of the Saunders-Roe SR.53, which was itself an experimental combined jet-and-rocket interceptor aircraft. The SR.177 principally differed from the smaller SR.53 in its adoption of a nose-mounted aircraft interception radar unit, which allowed it to scan for and lock onto its own targets; a more powerful turbojet engine was also incorporated. In addition to British interests in the aircraft, the German Navy had also expressed their interest in the project and closely evaluated its progress with an eye towards its potential procurement. However, the SR.177 was ultimately cancelled as a result of changes in Britain's military policies in 1957. A much larger derivative of the SR.177 had been studied, which was designated as the SR.187, and was being developed with the intention of meeting the requirements of Operational Requirement F.155. However, this work was also cancelled in 1957. By the time of termination, approximately 90 per cent of the first prototype had been completed, while several other prototypes were in various states of completion. The prototypes were stored for several years while attempts were made to revive the project; while interest was present, including from Japan, nothing more came of the project and the remaining assets were broken up.

Saunders-Roe SkeeterThe Saunders-Roe Skeeter is a two-seat training and scout helicopter that was developed and produced by British manufacturer Saunders-Roe ("Saro") of Cowes and Southampton, in the United Kingdom. Work on what would become the Skeeter had been commenced by the Cierva Autogiro Company as the Cierva W.14. Following Saunders-Roe's takeover of Cierva's helicopter development contracts, it was decided to continue its projects, including the Skeeter. Despite an initial preference for the rival Fairey Ultra-light Helicopter, which had already been ordered, there was a reversal of fortune with interest from the Bundeswehr in the potential procurement of a large number of Skeeters. This led to the British order for the Ultra-light Helicopter being cancelled and the Skeeter effectively taking its place, which also served to guarantee an export order from Germany. During the late 1950s, the Skeeter entered service with the British Army Air Corps, the German Navy, and the German Army. It has the distinction of being the first helicopter to be used by the Army Air Corps. While some consideration had been made to developing a version of the Skeeter powered by a turbine engine instead of a piston engine, it was decided to produce the developmental Saro P.531 for this purpose instead of a more direct Skeeter derivative. In the 21st century, a number of examples are preserved as museum pieces in the UK, Germany, and Poland.

Saunders-Roe DuchessThe Saunders-Roe Duchess also known as the model P.131 was a British design for a large jet-powered flying boat envisaged by Saunders-Roe, based in Cowes on the Isle of Wight. The Duchess had been intended to follow on from the propeller-driven Princess and drew heavily upon its design. Being larger than preceding commercial flying boats, as well as the novel use of jet engines for such a vehicle, Saunders-Roe promoted the Duchess as representing the next generation of flying boats to various civilian airlines. During the early 1950s, it was also promoted for military applications such as aerial reconnaissance and military transport duties, as had been the Princess. An even larger flying boat, the Saunders-Roe Queen, was also proposed around the same time. Unlike the Princess, however, no examples of the Duchess ever flew; attempts to garner interest in the concept never resulted in any orders being placed for the type, thus it never left the drawing board.
