US confirms for first time it has deployed weapons in space

Air Force Secretary Troy Meink Announces On-Orbit Deployment

The U.S. military publicly acknowledged its orbital capabilities at the annual Air, Space, Cyber conference on Monday. Air Force Secretary Troy Meink told attendees that Washington has fielded active on-orbit space control weapons, designed to defend the Joint Force against hostile adversary action.

While Meink declined to disclose the specific mechanics or deployment timelines of the hardware, a U.S. Space Force spokesperson clarified that space control can refer to employing kinetic and non-kinetic means to affect adversary capabilities, adding that these capabilities can be employed for offensive and defensive purposes.

Strategic Ambiguity and Expert Assessment on Capabilities

The decision to withhold exact technical details is a deliberate strategic consideration. Juliana Suess at the German Institute of International and Security Affairs and an expert in space security noted that the capability of the weaponry could range from reversible interference, such as jamming, to kinetic, permanently destructive effects, and that it is based in space rather than being a missile based on Earth that could hit a satellite in orbit.

Astronomer Jonathan McDowell, who spent decades compiling a list of rocket launches and worked at the Harvard-Smithsonian Center for Astrophysics until he retired this year, told the Guardian it was reasonable to assume Washington had such weapons in space, probably jammers, as it had already deployed several satellites with secret payloads. Victoria Samson, the Secure World Foundation’s chief director of space security and stability, suggested that the public confirmation serves a dual purpose.

“It is possible it’s meant to be used as a deterrent effect for adversaries to think twice before interfering with US space systems. I also believe that it’s meant to solidify the Space Force as a warfighting branch, as opposed to a military branch that supports other branches.”

International Reaction from China and Russia

Global powers responded swiftly to the public disclosure. China’s foreign ministry stated that Washington was preparing for war in outer space, and warned against turning space into a battlefield, as well as an arms race there. In Moscow, the Kremlin spokesperson, Dmitry Peskov, told reporters that Russia believed that space must be free of any weapon and called for the complete demilitarisation of space.

Analysts expect that Beijing and Moscow could respond by demonstrating their own space capabilities, as they have done previously. Jonathan McDowell noted that Russia and China would now respond in kind and deploy their own weapons, finding it questionable whether this is in the US national interest in the long run. In 1967, superpowers and other countries signed the outer space treaty, which banned weapons of mass destruction in orbit, although the text does not contain a general prohibition on placing conventional weapons in Earth orbit.

Modernizing the Force for a Rapidly Accelerating Threat Environment

Alongside the space weapons disclosure, Meink described a rapidly accelerating threat environment facing the U.S., saying that adversaries were exploiting new technologies and arguing that the U.S. needed to increase combat power faster and more affordably, including through autonomous systems and cheaper weapons. His comments came as governments are reassessing what weapons and defense systems they’ll need to defend themselves against an increased threat from hybrid attacks, with the fighting in Ukraine in particular highlighting how warfare is moving more towards autonomous systems, AI and drones.

“We will dramatically increase our combat power by adding large numbers of highly autonomous systems. Because of the steps we’re taking today, we’ll have a radically different-looking Air Force by 2032.”

The Space Force itself remains a branch created by President Donald Trump in 2019. Victoria Samson described the overall acknowledgement as a very destabilizing statement by the United States, while Jonathan McDowell warned that even radio jamming would be a big escalation of military activity in space.
