Short S.5 Singapore I / S.19 Singapore III
The Singapore III reconnaissance and coastal patrol flying-boat was basically the production version of the earlier Singapore II, itself developed from the twin Buzzard-engined Singapore I of 1926.
The huge biplaned Singapores entered service with the RAF in 1934. Built with a deep, well -faired beamy hull constructed of duralium, the boat had a good seaworthy reputation and was quite maneouvrable on the water. While the book claimed a cruise of 105 knots, RNZAF crews seldom watched the wave tops go past at more than 80 knots. The endurance was some six and half hours at around a thousand feet, the low altitudes being little hindrance as the primary obser-vation device in those early days was the Mark One eyeball.
Thirty-seven Singapore IIIs were delivered to the RAF, entering service in the spring of 1935. The last few aircraft were withdrawn in late 1941, when they were transferred to the Royal New Zealand Air Force. Powered by four 730 hp Roll Royce Kestrel VIII/IX gly-col-cooled engines mounted in two tan-dem pairs between the fabric-cov-ered wings.
