Short S.26, X8274, moored on the Medway at Rochester, Kent, before being flown to Blackburn Aircraft Ltd at Dumbarton for the installation of radar equipment. X8274, originally built as G-AFCJ "Golden Fleece" for Imperial Airways, was impressed and modified for RAF service before her launch at the Short Brothers Rochester works on 8 July 1940. Military modifications included the installation of two dorsal and one tail Boulton & Paul gun turrets, each mounting four Browning .303 machine guns, underwing racks for eight 500-lb bombs, armour plating for the crew positions, and stowage for floats and reconnaissance flares. After being equipped with ASV radar, X8274 became the first of three S.26s to join 'G' Flight - later No. 119 Squadron RAF - of Coastal Command at Bowmore on 24 December 1940. In June 1941, the S.26s were attached to No. 10 Squadron RAAF to undertake special long-range supply flights to Gibraltar and the Middle East and, on 20 June 1941, while outward bound for Gibraltar, X8274 ditched off Cape Finisterre after developing engine trouble, and foundered.
