What were the key technological developments affecting the cold war in the 1950s

Many of the military technological advancements that have been made in the last 60 years can be attributed to the Cold War. Much of the technology developed during the period of the Cold War is still in use today by the military and government. Advancements in offensive technology are well known to just about everyone in the way of nuclear energy harnessed in the form of the nuclear bomb, but little is known about the battle for information during the Cold War. The Cold War produced some of the most advanced technology used in the fields of detection and reconnaissance in history. The United States’ detection and reconnaissance technology played a major role against communism during the Cold War, and these types of technology still play roles today.
