WASHINGTON | The United States has publicly acknowledged for the first time that it has deployed weapons in space, marking a significant shift in the Pentagon’s disclosure of its military capabilities in orbit amid growing competition with China and Russia.
Air Force Secretary Troy Meink made the announcement Monday at the Air and Space Cyber Conference in Maryland, saying the United States now has “on-orbit space control weapons” capable of defending U.S. forces against hostile action. He did not identify the weapons, disclose how many have been deployed or explain how they operate.
The disclosure comes as the U.S. military places greater emphasis on protecting satellites and other space-based systems that support communications, navigation, missile warning and military operations. The U.S. Space Force has described space as increasingly contested, with Russia and China developing capabilities intended to disrupt, disable or threaten satellites.
The acknowledgment also follows years of growing concern over anti-satellite technology. In 2024, U.S. officials publicly warned that Russia was developing a potentially dangerous anti-satellite weapon that could be launched from space, although the White House said at the time that the threat was not considered imminent.
The United States has itself demonstrated anti-satellite capabilities for decades. In September 1985, an Air Force F-15 launched an ASM-135A anti-satellite missile that destroyed the Solwind P78-1 satellite in orbit. The Air Force said the test was the first time a satellite had been destroyed from an aircraft and was the only operational use of that particular anti-satellite missile.
The creation of the U.S. Space Force in December 2019 formalized the growing military importance of space. It became the sixth branch of the U.S. armed forces and was established specifically to organize, train and equip personnel for space operations and to protect U.S. interests and capabilities in the domain.
The latest announcement does not mean that international law prohibits all weapons in space. The 1967 Outer Space Treaty bars countries from placing nuclear weapons or other weapons of mass destruction in orbit or stationing them in outer space. It also prohibits military bases, weapons testing and military maneuvers on the Moon and other celestial bodies. The treaty does not contain a blanket prohibition on every type of conventional weapon in orbit.
That distinction has become increasingly important as military powers develop systems that can interfere with satellites without necessarily destroying them. The United States, for example, has expanded electromagnetic warfare capabilities designed to disrupt satellite communications, while its Space Development Agency is building increasingly sophisticated satellite networks for missile warning, tracking and defense.
The Pentagon’s disclosure therefore represents more than a new weapons announcement. It makes public a capability that the U.S. military has previously discussed largely in terms of defending satellites and maintaining freedom of action in space.
Meink also said the Air Force is expanding its use of autonomous systems and expects the service to look “radically different” by 2032, including greater reliance on one-way attack drones.
For the United States and its rivals, the development underscores how space has evolved from a domain dominated by communications and scientific exploration into an increasingly important military theater. The challenge now is whether greater transparency about space weapons will strengthen deterrence or accelerate an arms race in orbit.
