U.S. Space Force confirms first deployment of weapons in orbit

The U.S. Space Force announced on Thursday that it has deployed weapons in orbit, the first time the United States has confirmed armed space assets. The statement came from the Space Force’s public affairs office in Washington, D.C., and was issued after a briefing with senior lawmakers. The agency said the weapons are part of a new “space operations” capability designed to protect U.S. satellites and deter hostile actors from disrupting critical communications, navigation and intelligence services.

The move follows a rapid build‑up of space power by China and Russia, which have both tested anti‑satellite missiles and announced plans to field their own space weapons. The United States has long kept its space armament program secret, citing national security and the need to avoid provoking an arms race. The Space Force’s disclosure comes as the U.S. government pushes for clearer rules on space conduct and seeks to reassure allies that American satellites are protected. Experts say the weapons could be kinetic kill vehicles, directed‑energy lasers or other systems that can disable or destroy satellites without firing a traditional missile. The Pentagon said the new capability will be used only as a last resort, but the fact that it exists signals a shift in how the U.S. views space as a contested domain.

In the briefing, Space Force officials said the weapons are already in orbit and are tested on a small number of U.S. satellites. They added that the system can be activated quickly if a hostile satellite is detected. The announcement prompted a mix of reactions. Some lawmakers praised the transparency, arguing that it helps prevent misunderstandings in space. Others warned that revealing the details could spark a new arms race and called for an international treaty to limit space weaponization. The U.S. has already urged the United Nations to revisit the Outer Space Treaty, which prohibits weapons of mass destruction in orbit but does not forbid conventional weapons.

The next steps for the U.S. include formalizing the policy through a new space strategy and engaging with allies to set norms for space conduct. The Space Force will likely expand the program and conduct more tests, while the Department of Defense will coordinate with the intelligence community to monitor other nations’ space activities. Internationally, the announcement has prompted discussions in the U.N. General Assembly and the European Union about creating a framework to prevent an escalation in space weaponry. The U.S. will also face pressure to balance its defensive posture with the need to keep space operations open for civilian use, such as GPS and weather satellites, which millions of people rely on daily.
