The CIA played a leading role in orchestrating propaganda efforts in the lead up to the ill-fated Bay of Pigs invasion of April 17, 1960, particularly via its broadcasting front organization, Radio Swan.
“Project officers … consulted with Voice of America and the United States Information Agency on propaganda operations,” Agency internal documents reveal.
“There were many discussions with the Federal Communications Commission on the licensing of Radio Swan and with the Defense Department concerning its cover. The State Department was regularly consulted on political matters.”
As the actual Cuban invasion approached “Radio Swan and other outlets were broadcasting 18 hours a day on medium-wave and 16 hours on short-wave. Immediately after D Day, these totals were increased to 55 hours and 26 hours, respectively. Fourteen frequencies were used. By the time of the invasion a total of 12,000,000 pounds of leaflets had been dropped on Cuba.”
