Summary of "Challenges to Segurity in Space" (2022)

Core Content

This report discusses the growing challenges to U.S. space security in an era of global competition and expansion. It highlights the increasing reliance on space-based capabilities for both military and civilian functions, as well as the development of counterspace technologies by China, Russia, and other nations.

Main Threats to U.S. Space Security

• Space Proliferation and Expansion:

  • The number of operational satellites from China and Russia has grown by approximately 70% between 2019 and 2021, following a 200% increase from 2015 to 2018.
  • Space capabilities are being developed across multiple domains, including satellite communications (SATCOM), remote sensing, navigation, and science/technology demonstration.
  • The militarization of space is increasing, with both China and Russia integrating space and counterspace capabilities into their national and warfighting strategies.

• Space Debris and Collisions:

  • The risk of collisions in low Earth orbit (LEO) is rising due to the increase in space launches and the fragmentation from past ASAT tests and collisions.
  • This trend is expected to continue through at least 2030, creating potential threats to satellites and space operations.

• Counterspace Capabilities:

  • Competitor nations are developing and deploying various counterspace technologies to degrade or destroy U.S. and allied satellites.
  • These include physical and cyber attacks on ground infrastructure, jamming of navigation and communication satellites, and the use of ASAT missiles.
  • China tested an ASAT missile in 2007, creating a debris cloud that still poses a threat to satellites in nearby orbits. Russia destroyed one of its derelict satellites in 2021 using an ASAT missile.

• Nuclear and Electromagnetic Threats:

  • Nations with nuclear weapons could potentially conduct high-altitude nuclear detonations to create widespread electromagnetic disruptions, damaging or destroying satellites.

Key Players and Their Strategies

China

• Goals: To become a leading space power and establish global space norms.
• Space Program: Managed by the People's Liberation Army (PLA), China's space program includes both civilian and military applications.
• Military Strategy: Emphasizes "informatized warfare" and the importance of space in modern military operations.
• Counterspace Development:
  • China has developed ASAT missiles and mobile jammers to deny U.S. and allied SATCOM and GPS capabilities.
  • It has a large ISR satellite fleet, second only to the U.S., with over 250 systems as of January 2022.
  • China is advancing in quantum communication with the QUESS satellite, which could enable secure communications.
  • China is also developing multiple SATCOM constellations in LEO, though their effectiveness remains uncertain.

Russia

• Goals: To challenge U.S. dominance in space and reduce reliance on U.S. systems like GPS.
• Counterspace Development:
  • Russia has developed and tested ASAT weapons and has created a separate space force.
  • It regularly expresses concerns about space weapons and is pursuing legal space arms control agreements to limit U.S. space capabilities.

Emerging Challenges

• Iran and North Korea:
  • Both are developing electronic warfare (EW) capabilities to deny or degrade space-based communications and navigation.
• Global Space Services:
  • The proliferation of space services across more nations is increasing the vulnerability of all countries to space disruptions.
• Orbital Congestion:
  • As more satellites are launched, the risk of collisions and debris increases, affecting both military and civilian operations.

Key Space Issues Through 2030 and Beyond

• Reusable Space Technology:
  • The growth of reusable launch vehicles is reducing the cost and increasing access to space for more countries.
• Human Spaceflight and Cislunar Operations:
  • China has launched a robotic lander and rover to the Moon's far side and is conducting lunar and Martian exploration missions.
• Space Debris and Orbital Collisions:
  • The risk of collisions is growing due to the increasing number of satellites and debris, with potential long-term impacts on space operations.
• Beyond Earth Orbit:
  • The report includes a new section on space operations beyond Earth orbit, emphasizing their strategic and operational importance.

Space Strategy and Doctrine

• China's Peaceful Use of Space:
  • China advocates for the peaceful use of space and is pursuing UN agreements on the nonweaponization of space.
  • However, it continues to develop counterspace weapons and integrate them into joint military operations.
• Military-Civil Fusion:
  • China emphasizes the use of dual-use technologies and policies to enhance its military capabilities.
  • It collaborates with civilian organizations, including universities and research institutions, to support its military space efforts.
• Strategic Support Force (SSF):
  • Established in 2015, the SSF integrates cyberspace, space, and electronic warfare capabilities.
  • It is divided into two main departments: the Space Systems Department (SSD) and the Network Systems Department (NSD).

Summary of Space Capabilities

• Remote Sensing and ISR:
  • Used for military and civilian applications, including surveillance, mapping, and intelligence gathering.
  • China's ISR satellites provide electro-optical and SAR imagery, as well as electronic and signals intelligence data.
• Satellite Communications:
  • Enables beyond-line-of-sight communication, including for military and civilian use.
  • China has over 60 communications satellites, with at least 4 dedicated to military use.
• Positioning, Navigation, and Timing (PNT):
  • China's BeiDou system is an independently developed PNT service, providing high-accuracy navigation for civilian and military use across many countries.

Conclusion

The report underscores the increasing competition in space and the need for the U.S. to maintain its dominance in this domain. As China and Russia continue to expand their space and counterspace capabilities, the U.S. must adapt to ensure the security and reliability of its space assets. The report also highlights the importance of addressing space debris and orbital congestion to prevent long-term disruptions to global space operations.
