ww2dbaseThe program that was later codenamed VENONA began in Feb 1943 by the Signal Intelligence Service of the United States Army. It began per the orders of US Army Deputy Chief of Military Intelligence Carter Clarke who distrusted the Soviet Union for its pre-war collaboration with Germany and the potential that it might sign a separate peace treaty with Germany. It studied intercepted Soviet communications by American, British, and Australian listening posts. Most of the intercepted messages were obtained between 1942 and 1945, almost most of them were not deciphered until 1946. Through some of these messages the United States learned of the Soviet attempts to obtain information on the Manhattan Project. Later during the Cold War the VENONA project was instrumental in exposing Julius and Ethel Rosenberg as Soviet spies. The program was canceled in 1980, and the program records began to be revealed to the public in 1995. ww2dbase
