Many of the military technological advancements that have been made in the last 60 years can be attributed to the Cold War.

The Cold War Project Group Online claims “the advancement of technology during the Cold War was greater than that of any one time period” (“The Arms Race”). The war developed nuclear missiles and many other technological advancements taking the world into a new era, the Nuclear Era. It was estimated at one time the United States and the Soviet Union could nuke the world seven times over; the governments realized the pointlessness of so many nuclear missiles and turned their attention toward other ways to get an upper hand in the conflict. Tensions ran high during this time; without military confrontation, research and resources were redirected towards other fields of technology such as detection systems, surveillance equipment, and underwater technologies.
Hope this answers your question!
