US's Orbital Weapons: The Limits of Global Pacts Governing Space Militarisation, Pg16

Key Highlights:

• The United States publicly confirmed on September 14, 2026, that it has active "on-orbit space control weapons" deployed in space.
• This marks the first such official admission by any nation regarding the deployment of weapons in Earth's orbit.
• U.S. Air Force Secretary Troy Meink stated these weapons are capable of defending joint forces against hostile adversary actions.
• China and Russia immediately reacted, urging the U.S. to cease expanding military capabilities in space and calling for complete demilitarization of outer space.
• The U.S. did not disclose the specific nature or number of these deployed weapons.

Detailed Insights:

• The U.S. Space Force indicated that "space control" involves employing both kinetic and non-kinetic means for offensive and defensive purposes.
• Experts suggest the deployed weapons are likely non-kinetic, such as jammers or electronic warfare systems, to avoid creating hazardous space debris.
• The militarization of space includes capabilities like Earth-to-space anti-satellite missiles, space-to-space weapons, and space-to-Earth systems.
• Four nations—the U.S., Russia, China, and India—have publicly demonstrated anti-satellite (ASAT) capabilities through tests.
• The Outer Space Treaty of 1967 prohibits placing nuclear weapons or other weapons of mass destruction in orbit but does not explicitly ban conventional weapons.
• Attempts to create a comprehensive international legal framework, such as the Prevention of an Arms Race in Outer Space (PAROS) treaty, have not succeeded due to lack of consensus among major space powers.
• China and Russia previously proposed a treaty to ban all weapons in space, but it excluded Earth-to-space weapons and did not gain traction.
• The Artemis Accords, a U.S.-led framework for civil space exploration, promotes peaceful uses but does not restrict the deployment of weapons by signatories.

Key Concepts Involved:

• Weaponization of Space: The development and deployment of military assets in outer space designed to attack space-based or terrestrial targets.
• Outer Space Treaty of 1967: A foundational international treaty that prohibits weapons of mass destruction in space and limits military activities on celestial bodies.
• Anti-Satellite (ASAT) Weapons: Systems designed to destroy or incapacitate satellites in orbit, which can be kinetic (physical destruction) or non-kinetic (jamming, cyberattacks).
• Prevention of an Arms Race in Outer Space (PAROS): A United Nations initiative aimed at establishing a legally binding instrument to prevent the weaponization of outer space.
