Venona project The Venona project was a counterintelligence program initiated by the United States Army's Signal Intelligence Service (later the National Security Agency) that ran for nearly four decades, spanning 1943 to 1980. The purpose of the Venona project was the decryption of messages transmitted by the intelligence agencies of the Soviet Union, e.g. the NKVD, the KGB (First Chief Directorate) and the GRU (military intelligence). During the 37-year duration of the Venona project, the Signal Intelligence Service obtained approximately 3,000 Soviet messages (only some of which were ever decrypted); the Signal-Intelligence yield included discovery of the Cambridge Five espionage ring in the UK and Soviet espionage of the Manhattan Project in the U.S. The Venona project remained secret for more than 15 years after it concluded, and some of the decoded Soviet messages were not declassified and published until 1995.
