The Short S.26 G-class was a large transport flying-boat with non-stop transatlantic capability. Three aircraft were built for Imperial Airways, subsidised by the Air Ministry in anticipation of military use. All three were impressed into military service.
The S.26 was designed as an enlarged Short C-Class Empire flying boat, also incorporating features from the Short Sunderland. Greater use of extrusions in the structure, rather than bent sheet sections, compared to the C-Class aircraft, helped to keep the weight down. It was powered by four 1,400 hp (1,044 kW) Bristol Hercules sleeve valve radial engines, and it was designed with the capability of crossing the Atlantic without refuelling, and was intended to form the backbone of Imperial Airways' Empire services. The plan was for the first aircraft to make long range runs, the second would operate medium length (2,000 miles) flights with a dozen passengers, and the third would make short range (1,000 miles) trips with 24 passengers. It could fly 6,000 miles unburdened, or 150 passengers for a "short hop". The S.26/M version had defensive armament of 12 0.303 inch machine guns in two dorsal, and one tail, Boulton Paul BPA Mk II four-gun turrets. Offensive armament was eight 500 lb (227 kg) bombs under the wings. There was internal stowage for 20 reconnaissance flares, 28 flame floats and 8 smoke floats. Air to Surface Vessel (ASV) radar was fitted, plus armour plating for the internal fuel tanks and the crew stations.
On 21 July 1939, the first aircraft, (G-AFCI "Golden Hind"), was first flown at Rochester by Shorts' chief test pilot, John Lankester Parker. On 24 February 1940, the second (G-AFCJ "Golden Fleece") flew, and the third (G-AFCK "Golden Horn") flew on 8 July 1940. Although two aircraft were handed over to Imperial Airways for crew training, in 1940 all three were impressed (along with their crews) into the RAF, before they could start civilian operation. They were modified by Shorts to S.26/M military configuration before delivery to the RAF as X8275, X8274 and X8273 respectively. After modification at Rochester, Air to Surface Vessel (ASV) RDF (later called Radar) was fitted by Blackburn Aircraft Limited at Dumbarton in Scotland.
