In June 1966, Helms was appointed director of Central Intelligence. At the White House later that month, he was sworn in during a ceremony arranged by President Lyndon Baines Johnson. In April of the prior year, John McCone resigned as DCI. Johnson then had appointed Admiral William Raborn, well regarded for his work on the submarine-launched Polaris missile, as the new DCI (1965–1966). Johnson chose Helms to serve as deputy director of Central Intelligence (DDCI). Raborn and Helms soon journeyed to the LBJ Ranch in Texas. Raborn did not fit well into the institutional complexities at CIA, with its specialized intellectual culture. He resigned in 1966.
