The United States confirms for the first time that it has deployed “on-orbit” space control weapons, with US officials saying they are meant to help defend US forces against hostile actions in space. Air Force Secretary Troy Meink says the capability is critical to US military and economic security. A US Space Force spokesperson says the weapons can defend the “Joint Force” but neither source provides specifics on what has been placed in orbit.

The disclosures come as the US frames space as increasingly contested, citing concerns about activities by Russia and China. The terminology used by US officials describes “space control” as using both kinetic and non-kinetic means, which could include actions such as jamming or other interference with adversary systems. Analysts cited by Dawn say the announcement is likely to intensify fears of a weapons race and highlights a gap in comprehensive legal rules for conventional space weapons.

Russia and China react with warnings against “weaponising” space. China calls for the US to stop expanding military capabilities in outer space, while Russia urges space to remain free of any weapons and promotes demilitarisation. Other reporting places the move within the broader historical context of Cold War-era militarisation and the 1967 Outer Space Treaty, which bans weapons of mass destruction in orbit but leaves uncertainty for other weapon types.
