The geopolitical rivalry between the United States and the Soviet Union between 1947 and 1991 was fought not only through proxy wars and diplomatic brinkmanship, but through an unprecedented state-funded technological arms race. The competition to achieve supremacy in ballistic rocketry, nuclear physics, satellite reconnaissance, microelectronics, and digital communications laid the foundational infrastructure for the modern internet and aerospace industries.
This historical overview details the Space Race (Sputnik to Apollo 11), the origins of DARPA and the ARPANET, early silicon microelectronics, and the Strategic Defense Initiative (SDI).
