Operation 40 was a covert CIA task force established around 1960, primarily composed of Cuban exiles, with the objective of overthrowing Fidel Castro’s regime in Cuba. The group engaged in intelligence-gathering, sabotage, and assassination planning, notably participating in the failed Bay of Pigs invasion in April 1961. Beyond Cuba, Operation 40’s activities have been linked to various geopolitical events, raising questions about its broader impact on global covert operations.
