Aéronavale
In 1929, the Royal Air Force needed urgent replacements of the Supermarine Southampton IIs then operated by No. 203 Squadron RAF based at Basra, Iraq. The Air Ministry issued Specification S.18/29 to specifically cover the procurement of a military variant of the Short S.8 Calcutta, similar to the S.8/2 Calcutta then being designed in collaboration with Breguet for Aviation Navale (French Naval Aviation). The new RAF version had Shorts designation S.8/8 and RAF designation Rangoon, and three examples were initially ordered.
