US space weapon announcement comes amid deepening space race, experts say

The United States’ announcement this week that it has deployed orbiting space weapons could deepen a space race with competitors China and Russia, and it necessitates closer dialogue with the powers about space militarization, defense analysts said.

Air Force Secretary Troy Meink offered no details about the nature or makeup of the weapons but described them as “on-orbit space control weapons capable of defending the joint force against hostile adversary action.” He made the surprise admission during his keynote address Monday at the annual Air, Space and Cyber Conference at National Harbor, Md.

A Space Force spokesperson said the weapons were deployed to increase “readiness against existing threats,” but declined to provide additional detail.

“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and even destruction, if necessary,” the spokesperson said in an emailed statement under the condition his or her name not be published. “These capabilities can be employed for offensive and defensive purposes at the direction of combatant commands.”

The weapons could carry capabilities from directed energy to electromagnetic spectrum jamming technology to kinetic capabilities like missiles, according to experts. The weapons are likely to be designed for use from space against threats in space and not against direct threats on the ground, said Philip Sheers, a defense fellow at Washington, D.C.-based think tank The Center for a New American Security.

Meink has not commented on why he chose this week to unveil the existence of the space weapons. The Space Force spokesperson did not address questions about the timing. Sheers speculated it could indicate that the U.S. believes competitors are deploying their own space weapons.

“‘It stands to reason that this is perhaps a response to some kind of burgeoning or latent capability the United States perceives in its adversaries, which there’s plenty of evidence for,” Sheers said.

U.S. intelligence revealed in 2024 that it believed Russia was developing space-based nuclear weapons, which would violate the 1967 Outer Space Treaty. Moscow has denied such a program, and Dmitry S. Peskov, the Kremlin spokesman, said Tuesday that Russia would push for the demilitarization of space among the international community.

China also condemned the U.S. space weapons on Tuesday.

“We urge the U.S. side to stop expanding its military capabilities and preparing for war in outer space,” foreign ministry spokesman Guo Jiakun said in a news briefing.

Despite their objections, the deployment of American weapons in space is likely not a surprise to those adversaries, said Dan Hart, a senior fellow with the D.C.-based Atlantic Council’s GeoTech Center.

“The argument could be made that China and Russia have been escalating, and (the U.S. is) responding,” Hart said.

The Cold War-era Outer Space Treaty does not ban weapons from space but urges that space be reserved for “peaceful purposes” and prohibits the deployment of weapons of mass destruction, including nuclear weapons, from space and the moon.

Meink’s announcement could open the gates for new dialogue around space militarization and for cooperation on civil space affairs, said Hart, who has long called for the United States and China to cooperate on space activities.

“The Outer Space Treaty absolutely needs to be expanded upon,” Hart said. “It definitely needs work, and I would say shame on us globally for not picking up the pen.”

The space weapons announcement came just ahead of Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, telling U.S. troops this week they should begin preparing for conflict in all domains, including on and around the moon.

Sheers and Hart both said they could not envision a true space conflict soon. But space weapons could be used in an earthbound conflict to protect the critical satellites advanced militaries rely on for communications, reconnaissance and command and control capabilities, they said.

“Barring an explicit deployment of a major adversary weapon capability in space, like an orbital nuclear weapon or something as drastic as that, I would not hold my breath for an imminent, full-on, high-intensity space confrontation without a precipitating terrestrial event in the near term,” Sheers said. “I think it is far more likely that terrestrial events, crises, and conflict that happen on Earth between countries on Earth bring in space as a natural extension of those crises.”

Hart warned that deepening militarization of space brings with it the potential for misunderstandings that could bring conflict between top powers who are deploying increasingly more technology into orbit.

“China is catching up with us in launch, and so … we’re going to have a lot of systems up there, and how do we avoid miscalculation?” he said. “There’s a lot of learning, and hopefully we find a way to have what we need to be confident that we can operate in space and avoid accelerating this ever-accelerating arms race.”
