The U.S. Has Deployed Weapons in Space

What does it mean for the future of warfare in space, and how far have the United States, China and Russia gone in developing the ability to disrupt, disable or destroy satellites that underpin military communications, navigation and surveillance, after Washington acknowledged for the first time that it has weapons deployed in orbit?

U.S. Secretary of the Air Force Troy Meink has now confirmed that the United States has deployed “on orbit” space-control weapons, publicly confirming an offensive military capability in space that Washington had not previously acknowledged.

“This is why the United States now has on-orbit space control weapons capable of defending the joint force against hostile adversary action,” Meink said in a keynote address at the Air & Space Forces Association’s Air, Space & Cyber Conference in National Harbor, Maryland.

Meink did not disclose what weapons had been deployed, when they were placed in orbit or whether they were capable of physically destroying satellites. He said the United States needed to remain prepared for “evolving threats”.

The U.S. Space Force later said: “Space control encapsulates the mission areas required to contest and control the space domain – employing kinetic and non-kinetic means to affect adversary capabilities through disruption, degradation and even destruction, if necessary.

“These capabilities can be employed for offensive and defensive purposes at the direction of combatant commands.”

The disclosure marks a significant shift in how openly Washington discusses offensive capabilities in orbit, as the United States faces growing competition with China and Russia over military space technology.

The Pentagon has for years warned that both countries are developing counterspace systems designed to interfere with U.S. satellites. The Space Force says China has developed space and counterspace capabilities as part of its military modernization and that Russia regards space as a potential warfighting domain.

The militarization of space is not new. The United States and Soviet Union deployed military satellites during the Cold War, but the development of systems capable of directly attacking satellites has accelerated in recent decades.

China demonstrated a direct-ascent anti-satellite, or ASAT, weapon in January 2007 by destroying its Fengyun-1C weather satellite. The test generated more than 2,500 trackable pieces of debris, according to NASA, creating one of the largest artificial debris clouds in low Earth orbit.

In 2008, the United States used a modified SM-3 missile to destroy the malfunctioning USA-193 satellite, demonstrating its own ability to conduct an anti-satellite interception.

Russia conducted a destructive ASAT test in November 2021 against its Cosmos 1408 satellite. NASA said the test generated at least 1,500 trackable fragments and created a debris cloud that threatened the International Space Station and other satellites in low Earth orbit.

The debris issue has become a major concern because objects in low Earth orbit can travel at roughly 7 to 8 km per second, according to NASA, meaning even relatively small fragments can cause severe damage in a collision.

In response, the United States announced in 2022 that it would no longer conduct destructive, direct-ascent ASAT missile tests, saying such tests create dangerous debris and threaten the long-term sustainability of space.

The new U.S. disclosure does not necessarily indicate a reversal of that pledge. The nature of the newly acknowledged systems remains unclear, and space-control weapons can include non-kinetic capabilities such as jamming or other forms of electronic interference that do not generate orbital debris.

The 1967 Outer Space Treaty, negotiated during the Cold War by the United States, Soviet Union and other countries, prohibits placing nuclear weapons or other weapons of mass destruction in orbit or stationing them in outer space. It does not impose a blanket ban on conventional weapons or military satellites.

That distinction has allowed major powers to develop military space capabilities while remaining within the treaty’s central restrictions.

The United States established the Space Force in December 2019 as the sixth branch of its armed forces and the first new U.S. military service in 73 years. Washington said the move reflected the growing importance of space to national security and the increasing ability of potential adversaries to threaten U.S. space assets.

The Trump administration has also made space-based interceptors a component of its planned Golden Dome missile-defense system. Meink said on Monday that the Space Force had “flight ready” hardware for space-based interceptors, although he did not provide details about their deployment.

The United States has increasingly framed space as a potential battlefield because modern militaries depend on satellites for communications, intelligence, surveillance, targeting, navigation and early warning.

The latest disclosure raises the prospect of a more explicit space arms race, even as Washington and other governments have sought to establish rules limiting the most destabilizing forms of anti-satellite warfare.
