Aspect of the Cold War

Cold War espionage describes the intelligence gathering activities during the Cold War ( 1947–1991) between the Western allies (primarily the US and Western Europe) and the Eastern Bloc (primarily the Soviet Union and allied countries of the Warsaw Pact). Both relied on a wide variety of military and civilian agencies in this pursuit. While several organizations such as the CIA and KGB became synonymous with Cold War espionage, many others played key roles in the collection and protection of the section concerning detection of spying, and analysis of a wide host of intelligence disciplines.

Zenit (Zenith) The Zenith Satellite program, was a satellite program developed by the Soviet Union and used from 1961 to 1994. During the course of its lifespan over 500 Zenith satellites were launched, making it the most used satellite system ever. The Soviets concealed the nature of the system by giving the satellites the Kosmos designation. The Zenith satellites had an advantage over the satellites developed by the United States, in that they could be reused. A total of eight variants would be developed for a variety of mission types, ranging from high resolution photography to ELINT to cartographic and topographic missions. Yantar The Yantar satellites, designed to replace the Zenit satellite system, are among the newest Russian satellites. Yantar satellites have been launched as recently as 2015. Two variants of the satellite have been developed for high resolution photography and for medium resolution broad spectrum imaging.

After 1990s new memoirs and archival materials have opened up the study of espionage and intelligence during the Cold War. Scholars are reviewing how its origins, its course, and its outcome were shaped by the intelligence activities of the United States, the Soviet Union, and other key countries. Special attention is paid to how complex images of one's adversaries were shaped by secret intelligence that is now publicly known. The Soviet Union proved especially successful in placing spies in Britain and West Germany. It was largely unable to repeat its successes in the 1930s in the United States. NATO, on the other hand, also had a few successes of importance, of whom Oleg Gordievsky was perhaps the most influential. He was a senior KGB officer who was a double agent on behalf of Britain's MI6, providing a stream of high grade intelligence that had an important influence on the thinking of Margaret Thatcher and Ronald Reagan in the 1980s. He was spotted by Aldrich Ames a Soviet agent who worked for the CIA, but he was successfully exfiltrated from Moscow in 1985. Biographer Ben McIntyre argues he was the West's most valuable human asset, especially for his deep psychological insights into the inner circles of the Kremlin. He convinced Washington and London that the fierceness and bellicosity of the Kremlin was a product of fear, and military weakness, rather than an urge for world conquest. Thatcher and Reagan concluded they could moderate their own anti Soviet rhetoric, as successfully happened when Mikhail Gorbachev took power, thus ending the Cold War.
