US Confirms Weapons in Orbit, Raising Space Arms Race Concerns
The United States has confirmed deploying weapons in orbit, intensifying international concerns over space militarisation, treaty disputes and a potential arms race.
The United States has confirmed that it has deployed weapons in orbit, marking a significant development in the militarisation of space and intensifying long-running debates over international space treaties. Air Force Secretary Troy Meink said the US had deployed “on-orbit space control weapons” designed to defend military forces against hostile actions.
The US has not disclosed what the weapons are, how they operate or whether they are intended to target objects in space or on Earth. The announcement comes as the Trump administration expands its focus on space-based defence, including the proposed Golden Dome missile defence system and plans for space-based interceptors.
Washington has previously raised concerns about Russia’s development of space-based anti-satellite capabilities and has also warned about China’s growing military capabilities in space. Much of the US military and civilian infrastructure depends on satellite communications and other space-based systems.
The Trump administration has directed the Pentagon to pursue space-based interceptors as part of its broader missile defence plans. The Congressional Budget Office has estimated that the space-based components of Golden Dome could cost up to USD 542 billion over 20 years.
The development also adds pressure to existing international debates. The 1967 Outer Space Treaty prohibits placing nuclear weapons and other weapons of mass destruction in orbit, while broader proposals to prohibit conventional weapons in space remain contested.
With Washington now acknowledging the deployment of orbital weapons, concerns over a potential space arms race and competing interpretations of international rules are likely to intensify.
