engines and
Handley Page auto-slots on the upper wings. The first prototype of the
Short Singapore, also known as the
Short S.5 (
military designation Singapore I), was a metal hull version of the wooden-hulled
Short Cromarty. The biplane design included a single fin and rudder, and was originally powered by two
Rolls-Royce Condor IIIA engines. Its maiden flight was made from
Rochester on 17 August 1926, piloted by Short's
Chief Test Pilot John Lankester Parker. The type did not enter production, but was used by Sir
Alan Cobham for a survey flight around
Africa. Registered
G-EBUP, it left Rochester on 17 November 1927 and arrived at the
Cape on 30 March 1928, returning to Rochester on 4 June 1928. It was displayed at the
Olympia in July 1929. The
Singapore II (manufacturer's designation
Short S.12) which followed was a development of the Singapore I with four engines, mounted in tandem
tractor/
pusher pairs (also known as the
push-pull configuration). The single example of this aircraft to be built was first flown on 27 March 1930, also by John Lankester Parker. From the Singapore II came a design with four engines and triple fins. In 1933 the British
Air Ministry ordered four flying boats based on the Singapore II for trials with squadrons under
specification R.3/33. These would be followed by a further production order to specification R.14/34. These aircraft, the
Singapore III (manufacturer's designation
Short S.19), had all-metal hulls and fabric-covered metal flying surfaces. They were powered by four
Rolls-Royce Kestrel IX mounted between the wings in two tandem push-pull pairs, similar to the Singapore IIs. The crew of six was located in a central cabin and fore, aft, and midships open gun positions (
Vickers machine gun or
Lewis gun). A long-range fuel tank could be carried externally on the dorsal hull. The first Singapore III flew on 15 June 1934. Although obsolescent by the time the first aircraft entered service with
210 Squadron in January 1935, the type arrived just in time to benefit from the arms race of the late 1930s and 37 were built. Production terminated in June 1937. ==Operational history==
