'necessary facilities', which included Masirah. A Cabinet Office memorandum of 1945 recommended the acquisition of Masirah on a 99-year lease, US interests in the island notwithstanding (During World War II the United States also had a base on the island.). The Sultan was to be offered an annual payment of £3,750 with an initial premium of £7,500. The base continued to expand into the 1970s, supporting British and Oman forces fighting insurgents during the Dhofar Rebellion and providing transit facilities for long-distance RAF flights. The British military presence at RAF Masirah extended until 31 March 1977, when Sultan of Oman's Air Force (now the Royal Air Force of Oman) took over the base, which became first SOAF Masirah and then RAFO Masirah. In the 1970s, the base included a HF communications hub and a rear link to SAS units and british Royal Engineer Units based in Oman in support of the actions against rebels in the south of the country (RAF Salalah). United States' units used Masirah Island as a staging base in Operation Eagle Claw, the unsuccessful 1980 attempt to free US hostages then held in Iran. The island was subsequently used as a staging area for operations into Afghanistan in 2001. , the American private military contractor DynCorp had a contract to staff and serve a US military storage-depot at this base. Radio Relay Station In 1966 Masirah took on a new role, it became the base for the British Middle East Relay Station. This was built by the British Diplomatic Wireless Service to be a relay station for the World Service of the BBC. The station had been previously based in Somalia and Perim called the East Africa Relay Station. These stations were both closed as the politics of the region changed. The station was badly damaged by a Hurricane in 1976 but was rebuilt and handed over to the BBC in 1985. Ecology The island is an important hatching ground for loggerhead sea turtles, similar in importance to the beaches at Ras al Hadd and nearby Ras al-Jinz as a hatching ground for green sea turtles. Critically endangered humpback whales also migrate in the waters surrounding the island and Masirah gulf. Economy Historically, the island had copper ore mining dating back to the Bronze Age. The fishing industry, building on a long tradition, is centered on the north coast, and includes a fish processing plant. See
