“The PLA probably considers DEWs [directed energy weapons] ideal counterspace systems because they can cause both reversible and nonreversible effects against satellites,” the Defense Intelligence Agency wrote in its unclassified report Challenges to Security in Space.
DIA's core assessment and timeline
The unclassified DIA report, released Monday and based largely on open-source information with a July cutoff date, warns that “by the late 2020s, China may field space-based directed energy systems and higher-powered ground-based directed energy systems capable of threatening satellites in higher orbits.” The report frames directed energy weapons (DEWs) as attractive counterspace tools because they can produce both temporary (reversible) and permanent (non-reversible) effects against space systems.
China’s growing orbital presence: more than 510 ISR systems
As of July 2026, the DIA noted Beijing’s intelligence, surveillance and reconnaissance (ISR) satellite fleet “contained more than 510 systems, having more than tripled since 2018.” The report highlights that many ISR satellites are affiliated with commercial and civil missions but stresses their dual-use nature, tied to Chinese military-civil fusion policies, meaning imagery and data could be used by the People’s Liberation Army. The report also calls out new concepts under development such as spaceplanes, and mentions DEWs could be placed on either conventional satellites or aboard spaceplanes for experimental or limited roles.

The DIA separates directed energy outcomes into reversible attacks—such as jamming signals or temporarily blinding optics (dazzling)—and non-reversible attacks that cause permanent damage. Examples in the report include temporarily blinding sensors with laser dazzlers, burning holes in satellites with lasers, frying electronics with high-power microwaves, coating solar panels with aerosol pigment, and even kinetic options such as direct-ascent intercepts or nuclear detonations in space. The report also notes physical manipulation—satellites that approach and tamper with other satellites—remains part of China’s known on-orbit toolset.
Recent incidents and the challenge of attribution
The DIA underscores practical risks with recent on-orbit encounters and breakups. In 2022 a Chinese satellite was observed grabbing another satellite and pulling it out of its normal geosynchronous slot into a “super-graveyard drift orbit,” illustrating the potential for close-proximity inspection or manipulation. Earlier this month, the report recounts, a Russian satellite, Kosmos 2612, may have passed within approximately 85 feet (26 meters) of ICEYE-X36, a U.S.-registered commercial imagery satellite that was providing imagery to Ukraine; no contact or damage was detected. A time-lapse of part of that encounter was posted by s2a systems.
The report also catalogs unexplained on-orbit breakups: a Russian inspector satellite launched in 2014 appeared to break up unexpectedly; around the end of July the Chinese reconnaissance satellite Yaogan 50-02 broke up; and on Sept. 13 the U.S. Cold War-era Farrah III (also known as USA 32) suffered a similar fate. The DIA emphasizes that malfunction, accident, and hostile action can be difficult to disentangle in space; directed energy attacks in particular could be hard to attribute because they can occur at a distance and allow a single platform to engage multiple targets quickly.
U.S., Russia, Iran and operational responses
The report places China’s activities in a broader context of counterspace competition. It notes Russia already fields ground-based laser systems capable of affecting U.S. and allied satellites, and records that in 2026, “with the onset of Operation Epic Fury, the U.S. and Iran took offensive actions against each other’s space capabilities to degrade and disrupt military actions on both sides.” The DIA also says Iran and North Korea will continue building civil and military space capabilities and maintain their jamming capabilities.
On the U.S. side, the report cites recent public disclosures: last month military officials acknowledged the U.S. has weapons in orbit, after Secretary of the Air Force Troy Meink said on the AFA 2026 Air, Space & Cyber Conference keynote that there are on-orbit weapons deployed to protect America’s interests in space. The U.S. Space Force described those capabilities in terms of a Space Control mission that can employ kinetic and non-kinetic means “to affect adversary capabilities through disruption, degradation and even destruction, if necessary,” and said such operations comply with international law and the Law of Armed Conflict.
What this means for the U.S. military, commercial imagery providers, and allied operations
- U.S. military: The DIA notes that even reversible attacks against space-based sensing and communications could materially affect combat operations, underlining why Space Control capabilities and readiness are central to military planners.
- Commercial imagery providers: The ICEYE-X36 encounter shows commercial satellites operating in conflict zones can face proximate risks from other nations’ on-orbit activity while providing imagery to customers, including governments.
- Allied operations and partners: China’s expanding dual-use ISR fleet and Russia’s and China’s ground-based laser activity mean allies that rely on space-based sensing and communications may also face reversible and non-reversible degradations of capability.
The DIA’s unclassified assessment does not provide technical specifics—whether lasers, high-power microwaves, particle beams or a mix—but its timeline is blunt: space-based DEWs are a plausible capability before the decade’s end. That projection, paired with recent on-orbit maneuvers and breakups, leaves a narrow margin for states and operators to sharpen detection, attribution and resilience measures before the risks become operational realities.
