The U.S. Space Force is opening up about its operation of orbital weapons, but not much beyond admitting that they exist.
During a “State of the Space Force” address at the Air & Space Forces Association’s Air, Space & Cyber Conference in National Harbor, Maryland, on Tuesday (Sept. 15), Chief of Space Operations Gen. Douglas Schiess stated unequivocally that the Space Force uses active space-based weaponry to support United States national defense.
“Let me be crystal clear: Today, Guardians operate on-orbit weapons that can defend the joint force against space-enabled attacks,” Schiess said, referring to the official name for Space Force personnel.
Space is central to national security infrastructure and warfighting efforts, and serves a critical role in how the military communicates, navigates, conducts operations and tracks threats globally. It’s become an increasingly contested domain, with adversaries developing technologies designed to disrupt or destroy satellites in orbit as well as hypersonic weapons that challenge ground-based-only defenses.
Schiess didn’t specify what kind of weapons the U.S. operates in orbit, how many there are, or what exactly they do. But the revelation that the Space Force is operating those kinds of assets is by itself a pretty hefty admission. The news expands the known scope of U.S. military activity in the final frontier, which already included the use of satellites for GPS, communications, missile warnings and other targeting and intelligence operations.
“Space is both a battlefield and the backbone of our joint force,” Schiess said. “We face determined and credible adversaries who are building counter-space systems at incredible speeds to target directly the United States’ space advantage.”
The chief adversaries are China and Russia, experts have said. Both nations have developed a range of counterspace capabilities intended to threaten or interfere with other satellites, including through electronic warfare and anti-satellite (ASAT) systems. Russia demonstrated as much in 2021, when it destroyed one of its own spacecraft with an ASAT missile, which created a cloud of more than 1,500 pieces of orbital debris.
The U.S. has been rapidly expanding its own military presence in orbit over the past decade or so, and is ramping up those efforts even more with plans for the implementation of President Trump’s Golden Dome missile interception system. In the last year alone, the Space Force has awarded more than $12 billion in major contracts to companies like SpaceX, Rocket Lab, L3Harris and Boeing for a wide range of services, including national security launches, space-based tracking satellites and other defense technologies.
Schiess pointed to the Victus Haze mission as an example of how the Space Force is getting ready to react to orbital threats on short notice. Rocket Lab carried out Victus Haze in June, launching an Electron rocket and interceptor spacecraft within just 17 hours of receiving notice from the Space Force, setting a launch turnaround record.
Schiess also highlighted the Space Force’s critical role in Operation Epic Fury and the ongoing engagement of U.S. military forces in Iran. “Guardians are not supporting from the sidelines as a nice-to-have, but we are delivering space power directly into the fight as a need-to-have,” he said. Schiess even gave an anecdotal example of the actions of one Guardian, “Specialist Gray,” in the heat of battle.
“Even as alarm red sirens were blaring and incoming missiles targeted her site, she courageously held the line, protecting forces, denying adversary capability, and delivering space effects until her commander had to literally pull her from the console to safety,” Schiess said.
Schiess described her operations before she was pulled from that console, giving some clue as to what exactly is meant by “on-orbit weapons.”
He said the Guardian in question needed to “reconfigure her weapon system and execute critical non-kinetic fires,” and went on to add, “She locked onto the target, optimized her weapon system and waged electromagnetic warfare against a determined adversary.”
Those descriptions offer at least some clues about the technologies involved. Phrases like “electromagnetic warfare” and “non-kinetic” could point to signal jamming technology or other non-physical means of disrupting a target.
Schiess said the Space Force intends to continue expanding its combat power with more robust architectures and the ability to respond with increasing speed to evolving threats. That proliferation on behalf of Golden Dome and other national security programs stands to deliver substantially more military hardware into orbit in the coming years, but Schiess framed the buildup around the prevention of conflict, rather than its provocation.
“Our aim is deterrence,” he said.
