Between 1959 and 1963, in addition to manned aircraft, Bomber Command also gained 60 Thor nuclear intermediate-range ballistic missiles dispersed to 20 RAF stations around Britain in a joint UK-US operation known as Project Emily. During the following twelve years, Bomber Command aircraft frequently deployed overseas to the Far East and Middle East. They served particularly as a deterrent to Sukarno's Indonesia during the Konfrontasi. A detachment of Canberras had a permanent base at Akrotiri in Cyprus in support of CENTO obligations.
