The Race Begins in the Cold War
The military interest in space started during the Cold War, when the United States and the Soviet Union viewed space as the next strategic frontier. What began as a competition to launch satellites quickly turned into a race for space dominance. Intelligence-gathering satellites, early warning systems, and intercontinental ballistic missile (ICBM) delivery concepts emerged, making space a key element in nuclear deterrence.
Space Becomes a Strategic Asset
By the 1970s and 1980s, satellites had become vital for navigation, communication, and surveillance. Both superpowers relied heavily on space-based systems to guide their forces and monitor each other’s military activities. This led to a new realization—control over space meant a significant military advantage on Earth. While the Outer Space Treaty of 1967banned the placement of nuclear weapons in space, it did not stop nations from using space for military support operations.
Post-Cold War Shifts
After the Soviet Union collapsed, the U.S. became the dominant space power. Space-based technology supported peacekeeping, humanitarian aid, and precision warfare. The 1991 Gulf War demonstrated how GPS-guided weapons and satellite communications could change the battlefield. This was a turning point—space was no longer just about watching the enemy; it was about actively shaping combat outcomes.
The New Era of Competition
In the 2000s, other countries, including China and Russia, began developing advanced anti-satellite (ASAT) weapons, cyber tools, and electronic warfare systems targeting space assets. The 2007 Chinese ASAT test, which destroyed a satellite, proved that space infrastructure could be vulnerable. The U.S. military realized that space superiority was not guaranteed and that its assets could be disrupted or destroyed in a future conflict.
Birth of the U.S. Space Force
In December 2019, the United States formally created the U.S. Space Force (USSF)—the first new military branch in over 70 years. Its mission is to protect U.S. space interests, defend satellites, and ensure freedom of operations in space. This marked a shift in doctrine—from using space as a support tool to treating it as a fully recognized warfighting domain, just like land, sea, air, and cyberspace.
Modern Military Space Doctrine
Today’s military space doctrine focuses on resilience and defense. This includes deploying satellites in constellations rather than single large systems, using maneuverable satellites, investing in space situational awareness (SSA), and integrating cyber defense measures. Nations are also exploring the use of small satellites and private sector partnerships to reduce vulnerability and increase flexibility.
Looking Ahead
The next phase of space doctrine will likely involve artificial intelligence for satellite operations, on-orbit servicing and repair, and even defensive capabilities that can intercept hostile actions in space. With more countries and private companies entering the space arena, the challenge will be balancing military security with international cooperation—and avoiding a new arms race above Earth.
