December 1953 – 22 April 1956 Operation Gold (the Berlin Tunnel) From 1955 to 1956 the CIA and British SIS tapped Soviet military phone and teleprinter cables in East Berlin from a 1,476-foot tunnel, unaware that a KGB mole had betrayed the plan before digging began. 4 February – 14 May 1943 Operation Mincemeat In 1943 British intelligence floated a dead man dressed as a Royal Marines officer ashore in Spain with forged letters pointing at Greece and Sardinia, to hide the coming invasion of Sicily. 1 July 1969 – 16 June 1975 Project Azorian (the Glomar Explorer) In 1974 the CIA used a purpose-built ship, passed off as Howard Hughes's deep-sea mining vessel, to lift part of the sunken Soviet submarine K-129 from 16,500 feet down in the Pacific. 24 November 1954 – 16 May 1960 The U-2 program and the 1960 shoot-down From 1956 the CIA's U-2 photographed the Soviet Union from 70,000 feet.

How these files are written

Each page is built from primary sources first: the State Department's Foreign Relations of the United States, CIA, NSA and FBI releases, congressional investigations and court records, all public domain, quoted briefly and linked. For 80 operations we compare the dates and outcome in a government source with Wikipedia and publish the result. Contested claims are labelled. Read the methodology.
