The Calcutta biplane flying boat originated from an Imperial Airways requirement to service the Mediterranean legs of its services from and to India. The Calcutta itself was derived from the Short Singapore military flying boat; however, it is noteworthy for being the first stressed skin, metal-hulled flying boat. Imperial Airways operated five of the seven Calcuttas produced, and a single
sale to the French government was followed by the French company Breguet licence-building four Calcuttas as the Bizerte. Further examples were built for the RAF as the S.8/8 Rangoon.
