Coverage of North Korea’s recent Party Congress has largely focused on its rejection of engagement with South Korea, leadership shifts, and renewed commitments to a growing nuclear arsenal. But one development deserves far more scrutiny than it has received.

Among the items on its five-year defense plan, Pyongyang listed “special assets for attacking enemy satellites in times of emergency.” That single phrase marks an important turning point: For the first time, North Korea has formally adopted counterspace weapons as a development priority. This is not offhand rhetoric from a state media commentary or an ambiguous research and development signal. It is a top-level policy directive, building on earlier legislation, from the country’s most important political event.

The counterspace objective is part of a broader modernization agenda spanning nearly every domain of military competition—from undersea deterrence to artificial intelligence to electronic warfare. Unlike the rest of these capabilities, however, the space component has no precursor in previous five-year plans. It represents a novel, qualitative, and potentially destabilizing expansion of strategic ambition into a domain where North Korea has, until now, been conspicuously absent.

“Special assets” is deliberately vague, but the most straightforward possibility is a direct-ascent anti-satellite (ASAT) weapon—a ground-launched missile adapted to reach orbital altitudes and kinetically destroy a satellite. China, India, and Russia currently possess these systems, and North Korea’s extensive ballistic missile program could provide the foundation for one. (The United States has tested and maintains a latent ASAT capability but does not operate or acknowledge possessing these weapons.) North Korea can already reliably launch missiles into low Earth orbit; the challenge, then, is having the precision needed to actually hit a satellite—something its guidance systems have historically lacked.

If North Korea is indeed eyeing an ASAT capability, testing would be a key indicator, and that comes with its own risks. The environmental consequences of North Korea’s previous missile tests have largely been confined to perturbing fish in the Pacific, but the effects in space, it goes without saying, would be far more severe. A direct-ascent ASAT test that destroys a target satellite would generate long-lasting space debris in an already crowded low Earth orbit. Similar tests by Russia in 2021, India in 2019, and China in 2007 all produced debris of varying lifespans; some debris from China’s test will remain on orbit until the latter half of this century.

However, the ambiguity of the phrase “special assets” also suggests another, more alarming possibility with far greater consequences. North Korea could be pursuing a nuclear-armed counterspace capability—that is, a weapon designed to detonate a nuclear warhead at high altitude, generating an electromagnetic pulse and propagating radiation that would disable satellites across wide swaths of orbit.

Though it may sound like science fiction, this is not a fanciful scenario; it is the crudest and most technically accessible counterspace attack available to a nuclear-armed state with a ballistic missile capability. Unlike a kinetic ASAT weapon, a nuclear ASAT does not require precision guidance and advanced technical capacity, only the ability to loft a nuclear warhead to orbital altitude and detonate it. North Korea can already do the first part, and the second is well within its demonstrated competence, should leader Kim Jong Un choose to allocate precious fissile material toward such a purpose.

Critically, unlike other nuclear states, North Korea can credibly employ such a capability in a war. Though Kim has military aspirations for space, North Korea currently has only one reconnaissance satellite of limited functionality in orbit and thus little to lose in that domain from an indiscriminate nuclear ASAT detonation. (There would, however, almost certainly be consequences for such an action back on Earth.)

The question is why Pyongyang would seek this capability now, and the answer seems to lie in Washington. North Korea is closely watching the United States’ most ambitious missile defense initiative in decades: the Golden Dome. Current plans envision a multilayered defense architecture spanning land, sea, and space. At its heart is a constellation of low-Earth-orbit satellites equipped with infrared sensors and, eventually, space-based interceptors designed to detect and destroy ballistic missiles during their boost and midcourse flight phases. The sensor backbone of the Golden Dome, the Space Development Agency’s Proliferated Warfighter Space Architecture, is being scaled up rapidly, too.

For North Korea, the Golden Dome represents a significant threat: If the United States can reliably detect and intercept North Korean intercontinental ballistic missiles, or ICBMs, during their most vulnerable phases of flight—boost phase, when they are relatively slow, hot, and visible to infrared sensors, or midcourse, when they are traveling predictably through space—then Pyongyang’s ability to hold the U.S. homeland at risk, and therefore its nuclear deterrent, would be seriously undermined. Whatever doubt exists about the Golden Dome’s scope, costs, and technical feasibility, North Korea has to presume the worst.

This is where the counterspace calculus becomes clearer. From a North Korean perspective, space-based sensors and possible interceptors would be the Golden Dome’s most critical—and most vulnerable—components. Without persistent overhead infrared tracking, ground-based radars cannot provide the early warning and continuous track custody needed to cue interceptors against fast-moving ballistic and hypersonic targets. North Korea’s strategists almost certainly understand this. The reference to “attacking enemy satellites in times of emergency” is likely a direct response to this emerging vulnerability.

A nuclear ASAT weapon—detonated in low Earth orbit during a crisis or at the outset of a conflict—would be a blunt but devastatingly effective tool against the space-based components of Golden Dome and even against the ability of the United States and its allies to carry out conventional military operations. A single warhead could degrade or destroy hundreds if not thousands of satellites, including those comprising the Golden Dome’s tracking and interceptor layers. As a U.S. Defense Department official told Congress in 2024, a nuclear detonation in space “could render low Earth orbit … unusable for some period of time.” But for a regime confronting what it perceives as an existential threat during a war, contaminating low Earth orbit to preserve its nuclear deterrent could be a grim but rational calculation.

North Korea’s counterspace ambitions cannot be assessed in isolation from its deepening relationship with Russia. Kim met Russian President Vladimir Putin at the Vostochny Cosmodrome in Russia’s Far East in 2023, and their 2024 comprehensive strategic partnership treaty directly alludes to space cooperation. Since North Korean troops were deployed to Ukraine, Pyongyang has received a variety of military-relevant technology and knowledge from Moscow in return. While tracking these transfers remains challenging, multiple U.S. officials warned in late 2024 and 2025 that Russia intended to share “advanced space and satellite technology” with North Korea.

Russia itself has extensive ASAT experience, from Soviet-era co-orbital interceptors to more recent direct-ascent and electronic warfare capabilities, and U.S. officials have also disclosed that Russia is developing a nuclear ASAT capability. Any transfer of expertise—whether in the form of technical knowledge, targeting data, or even components—would lower the barriers to a viable North Korean counterspace capability.

The Russia factor also intersects with the broader question of space technology transfer. North Korea’s reconnaissance satellite program has reportedly benefited from Russian technology and launch vehicle improvements, and the Party Congress’s call for “more evolved reconnaissance satellites” signals that Pyongyang intends to continue building out its orbital infrastructure. Both Russia and North Korea have joined the 1967 Outer Space Treaty, which explicitly prohibits the emplacement of nuclear weapons on orbit. The United States has argued that Russia’s planned nuclear ASAT weapon violates its treaty obligations, and North Korea certainly has shown little hesitation in the past to undertake activities that put it in violation of its international commitments.

While counterspace is the most serious addition to Pyongyang’s plans, Kim’s ambitions should also be read alongside the adjacent pledge in the Party Congress report to build “very powerful electronic warfare weapons systems to paralyze enemy command centers.” Electronic warfare and counterspace are deeply intertwined, and North Korea has already demonstrated significant GPS-jamming capabilities, which signals competence in the electromagnetic spectrum. Scaling this would be a significant undertaking, even with Russian support, but a counterspace strategy that combines nuclear or kinetic attacks on satellites with electronic jamming of ground stations and communication links would certainly be a formidable challenge to U.S. and allied space infrastructure.

Though considerable ambiguity remains about Pyongyang’s counterspace ambitions, several indicators will be worth watching in the years ahead.

First, we should look for a North Korean missile test on an unusually high-apogee trajectory. North Korea has previously tested ICBMs on lofted trajectories to avoid overflying neighboring states; the same technique could be used to demonstrate the ability to reach orbital altitudes with an ASAT payload. Second, improvements in North Korean tracking, guidance, and space situational awareness, particularly with help from Russian technology transfers, would suggest movement toward a more precise counterspace capability. Third, the pace and success of North Korea’s satellite launch program will matter, as each launch will improve the infrastructure and expertise that could support an ASAT mission. Finally, the United States could try to put diplomatic pressure on China by emphasizing the risks a nuclear detonation in space would pose to Chinese assets, including the crewed Tiangong space station.

In the meantime, Pyongyang’s new counterspace language should prompt a reassessment of how the United States and its allies think about the vulnerability of space-based missile defense. Golden Dome’s architects are designing for a world of great-power counterspace threats from China and Russia, but North Korea’s formal entry into this domain, however crude its initial capabilities, adds a new variable. The proliferated satellite architecture favored by the Space Development Agency is designed to be resilient against single, kinetic attacks. But it is not designed for, and may not survive, the electromagnetic and radiation effects of a nuclear detonation in orbit—which is precisely why Moscow is and Pyongyang may be seeking such capabilities.

If North Korea makes good on its stated intent, the assumed resilience of the Golden Dome’s satellite constellation will need to account for a threat that most missile defense planners have not prioritized: a nuclear ASAT attack from a desperate, risk-acceptant adversary with barely anything to lose in space. And as the last 20 years clearly attest, it would be a mistake to underestimate North Korea when it sets its mind to something.
