The Saunders-Roe SR.A/1 was a prototype flying boat fighter aircraft designed and build by Saunders-Roe. It was tested by the Royal Air Force shortly after World War II.

Design and development

The SR.A/1 was directly inspired by the (modest) successes experienced by the Imperial Japanese Navy with seaplane fighters such as the Nakajima A6M2-N (an adaptation of the Mitsubishi Zero) and the Kawanishi N1K. In theory, seaplanes were ideally suited to conditions in the Pacific theatre, and could turn any relatively calm area of coast into an airbase. Their main disadvantage came from the way in which the bulk of their floatation gear penalised their performance compared to other fighters. Saunders-Roe realised that the new turbojet engine presented an opportunity to overcome this drawback. Not requiring clearance for a propeller, the fuselage could sit lower in the water and utilise a flying boat-type hull. The company approached the Air Ministry with the idea then known as the SR.44 , which led to specification E.6/44 and an accompanying development contract for three prototypes in May 1944.

The first prototype flew on July 15 1947, and while it and its two sisters proved to have good performance and handling, the need for such aircraft had completely evaporated with the end of the war. Furthermore, the success of the aircraft carrier in the Pacific had demonstrated a far more effective way to project airpower over the oceans. In addition, the cockpit canopy was small and heavily framed, giving the pilot a poor view outside the aircraft. The project was finally abandoned in May 1951.

Although the aircraft never received an official name, it was referred to by company workers as 'Squirt'.

The first prototype, serial number "TG263", has been preserved, and is on display at Solent Sky (previously Southampton Hall of Aviation). Both other aircraft were lost in accidents during the four-year flight test programme.
