Supermarine S.6


The Air Ministry felt that it could no longer stand by and see foreign aircraft winning the Schneider Trophy contest, so it ordered a number of racing seaplanes and formed a special RAF High Speed Flight to enter them in the 1927 contest at Venice.

One of the types ordered was the Supermarine S.5, that won the race at a speed of 281.65 mph. Two years later (the contest became biannual from 1927) the success was repeated by a slightly larger machine on the same lines, the S.6, with a 1,900 h.p. Rolls-Royce R engine.

In 1929, the world absolute speed record went up to 358 mph when a British Supermarine S-6 seaplane made an official run.

In 1931 Britain gained the Trophy outright when the S.6B with its Rolls-Royce engine boosted to give 2.300 h.p. won the third consecutive contest at 340.6 mph over the 189 mile course. The S.6 and S.6B also set up new world speed records of 357.74 and 406.99 mph (29 September 1931) respectively. They were forerunners of Mitchell's Spitfire.
