The Critical Importance of Space to U.S. National Security

Bert Chapman

Space has become essential to all aspects of civilian and military space policy. In our personal lives cell phones use GPS satellites to track our locations, satellites are involved in multiple bank and financial transactions, and when we watch news and sports from domestic and international locales such as the Winter Olympics, we depend on satellites to transmit and receive these images. GPS guides commercial airlines and container ships to their locations along ambulances, fire departments, and police depending on GPS to execute their responsibilities. Storms such as hurricanes are also tracked by satellite.

Recent years have seen the establishment in the U.S. and other countries of government agencies aspiring to regulate the commercial space industry and space transportation This has also been true as the national militaries have also developed or are in the process of developing military forces and intelligence capabilities to defend space assets and monitor the capabilities and threats posed by hostile countries. Examples of some of these agencies for the U.S. and their allies include the U.S. Space Force, the 3 Canadian Space Division, the Australian Defence Force’s Space Command, Britain’s Royal Air Force U.K. Space Command, and France’s Air and Space Force. These military forces have also begun developing military doctrine to conduct operations in space.
