The October 1956 Suez Crisis brought relations between Britain and the United States to a low ebb. Eisenhower met with the new British prime minister, Harold Macmillan, in Bermuda in March 1957 and raised the possibility of basing US intermediate range ballistic missile (IRBM) systems in the UK. This came to be called Project Emily. There were also discussions on exchanging nuclear submarine propulsion technology for information on the British Calder Hall nuclear power plant, allowing the United Kingdom Atomic Energy Authority (UKAEA) to purchase uranium ore from Canada and co-ordinating the war plans of RAF Bomber Command with those of the Strategic Air Command.
