In the latest special edition of the Aerospace Advantage podcast, Episode 169 titled “Russian Nukes in Space? Understanding the Threat and Implications,” we delve into the evolving dynamics of space power, with a particular focus on recent developments regarding Russia’s space capabilities. Hosted by John “Slick” Baum of the Mitchell Institute, this episode features an in-depth interview with Col Charles Galbreath, USSF (Ret), Senior Fellow at the Mitchell Institute Spacepower Center of Excellence, exploring the critical implications of Russia’s potential deployment of nuclear weapons in space

Episode 169 – Special Edition: Russian Nukes in Space? Understanding the Threat and Implications – Mitchell Institute for Aerospace Studies

21 February, 2024

Discussion Overview:Emerging Threat from Russia: A new threat has emerged from Russia, involving a nuclear anti-satellite weapon that endangers a vast array of satellites. This weapon, with roots in the Cold War era, is nearing operational capability and poses a significant risk of debilitating attacks on both civilian and military satellites.
Nuclear Threats in Space: The potential deployment of nuclear weapons in space, including both detonation-capable and powered systems, presents indiscriminate hazards. The discussion touches on the historical precedent from 1962 and the limitations imposed by the 1967 Outer Space Treaty on nuclear power sources in space, highlighting the distinction between nuclear-powered spacecraft and weapons of mass destruction.

Impact of Space Warfare: The use of nuclear weapons in low Earth orbit could have lasting detrimental effects, endangering nearby satellites for months or even years and creating debris fields that could persist for decades. This situation would not only affect military and civilian satellites but also pose significant risks to human life in low Earth orbit, including those aboard the International Space Station.

Countering Adversary Threats: The conversation suggests that deploying a proliferation of low-cost satellites in low Earth orbit could serve as a countermeasure against adversaries’ capabilities. The need for a comprehensive approach encompassing intelligence gathering, budgetary robustness, and public education on the importance of space capabilities and the threats they face is stressed. Additionally, the importance of diplomatic efforts to establish norms against the deployment of weapons of mass destruction in lower Earth orbit is emphasized.

Key Themes Explored:
Emerging Threats: The episode sheds light on the newly emerged threat from Russia, involving a nuclear anti-satellite weapon that poses a significant risk to satellite arrays. This development, rooted in Cold War-era technologies, is nearing operational capability and could lead to debilitating attacks on satellite infrastructure.
Nuclear Hazards in Space: A detailed discussion on the potential hazards of deploying nuclear weapons in space, including both detonation-capable and powered systems, is presented. The historical precedents and the limitations imposed by international treaties, such as the 1967 Outer Space Treaty, are examined to highlight the distinction between nuclear-powered spacecraft and weapons of mass destruction.
Space Warfare Impact: The potential lasting effects of nuclear weapons detonated in low Earth orbit, including damage to nearby satellites and the creation of long-term debris fields, are analyzed. The episode also considers the implications for human life in low Earth orbit, such as the crew aboard the International Space Station.
Countermeasures and Diplomacy: Strategies for countering adversarial capabilities, such as the deployment of low-cost satellite constellations and the importance of diplomatic efforts to establish norms against weapons of mass destruction in space, are discussed as vital components of a comprehensive approach to space security.

This episode not only provides an analytical overview of the discussions surrounding the potential for Russian nuclear capabilities in space but also emphasizes the importance of vigilance, strategic resilience, and international collaboration to navigate the complexities of securing a sustainable and secure future for space activities.
