The original naval base was established as a fall-back for the British Eastern Fleet. Despite public pronouncements to the contrary, the official view was that the main base at Singapore would be untenable if the Japanese made serious headway in Malaya and Java – which, in the event, is what happened in 1942. The intention had been to operate from Trincomalee, Ceylon (now Sri Lanka). Upon inspection, however, the naval commander-in-chief, Admiral James Somerville found the port inadequate, vulnerable to a determined attack and open to spying. An isolated island base with a safe, deep anchorage in a suitably strategic position was required, and Addu City met the requirements. Once available, its facilities were used extensively by the Fleet.
