The head of U.S. Space Command, Gen. Stephen N. Whiting, has expressed serious concerns that Russia may be developing a nuclear anti-satellite (ASAT) weapon in orbit. Such a weapon could disrupt global communications, GPS systems, and daily life on Earth, according to Whiting. He made the remarks during an appearance on The General & The Journalist, a podcast by The Times.
Russia’s Potential Violation of the Outer Space Treaty
Whiting emphasized that deploying a nuclear ASAT weapon would violate the 1967 Outer Space Treaty, which prohibits placing nuclear weapons in orbit. Russia is a signatory to the treaty. The treaty also prohibits claims of sovereignty over space, treating it as a global commons.
Russia’s Space Capabilities and Motivations
Whiting noted that Russia remains a sophisticated space power despite economic sanctions. He suggested that Russia may be pursuing such a weapon to counter U.S. and NATO conventional military superiority. By targeting satellites, Russia could level the battlefield in its favor, according to Whiting.
Potential Consequences of a Nuclear ASAT Weapon
A nuclear detonation in low Earth orbit (100–1,200 miles above Earth) could have devastating consequences for both military and civilian infrastructure. Whiting warned that such an attack would put all satellites in low Earth orbit at risk, including those used for communications, navigation, and scientific research.
Russia’s Other Space Aggressions
Whiting also highlighted Russia’s sustained satellite communication and GPS jamming, which has reportedly put civilian airliners at risk. These actions are part of a broader strategy of increasing aggression in space, according to U.S. officials.
U.S. and NATO Response
In light of Russia’s actions, NATO and the European Union have discussed efforts to bolster Europe’s arms production. This comes as U.S. President Donald Trump has raised doubts about Washington’s commitment to the transatlantic alliance.
U.S. Intelligence and Verification
Whiting did not confirm the underlying intelligence but stressed the seriousness of the concern. The Pentagon has been contacted for further comment on the matter.
