Space Security Depends on Networks, Ground Systems and Supply Chains

Kari Bingen asks people to begin with the ordinary systems they already use: communications, GPS navigation, package tracking and financial transactions. Space underpins all of them. It also enables how the U.S. military commands forces, launches weapons and operates globally. That dependence, she says, is precisely why adversaries have spent decades developing ways to counter it.

The threat is not confined to an attack that physically destroys a satellite. Bingen describes an expanding counterspace toolkit: communications and GPS jamming, lasers that can blind satellites, ground-based missiles that can intercept them, and cyber capabilities. Russia’s 2021 anti-satellite test demonstrated the kinetic option; Bingen also points to reporting about a Russian nuclear weapon designed for orbit.

A ground-launched nuclear weapon would not make much sense as an anti-satellite system, she argues, because Russia already possesses nuclear-armed ICBMs. The more consequential possibility is a weapon placed in orbit and detonated there. The contrast is between a sniper rifle and a shotgun: an attack on a single satellite has a discrete target, while a nuclear detonation in low Earth orbit could affect thousands of commercial, civil and military satellites in that orbit.

The consequences would not be isolated to a space program. U.S. ships, aircraft and tanks are built around the assumption that space capabilities will remain available. If satellites are degraded or neutralized, Bingen says, the ability to project power and conduct military operations is significantly affected.

The core strategic problem is that space has become integral to civilian life and national security faster than its security architecture has matured. The United States has had decades to build doctrine, tactics and strategy for land, maritime and air operations. In space, Bingen says, military organizations are “building that airplane essentially in flight.”

Robert Lightfoot describes a shift away from the old model of government-led space systems: bespoke, exquisitely engineered satellites that took a long time to build, cost a great deal to operate and could be relatively fragile in orbit. Private investment and commercial development have changed the infrastructure model toward proliferated constellations—many spacecraft able to provide overlapping services.

That proliferation can create resilience. If an adversary destroys or disrupts one satellite, another may be able to take over. Lightfoot’s deterrence argument is straightforward: attacking an architecture with thousands of satellites is a different proposition from taking out two or three high-value assets. A commercial provider’s assessment during the war in Ukraine captured the logic, he says: “You don’t have enough jammers to take us all out. You can’t hit us all.”

But proliferation does not eliminate vulnerability; it relocates it. An adversary does not need to attack every satellite if it can find the critical point connecting a network to users and systems on Earth. The concentrated points of failure may be a data link, command function, network connection, ground station, terminal or supplier rather than the spacecraft itself.

? dan-smoot separates the underlying dependencies into two connected supply chains. The first is physical: space-grade raw materials and components must meet demanding assurance and purity requirements, because failures in orbit are expensive and difficult to remedy. The second is a data supply chain: the IT, networking and software systems that connect physical assets to users, operations and decisions. Both must be secured against malicious control or compromise.

Lightfoot uses GPS to show why a new satellite alone is insufficient. GPS signals can be jammed or spoofed. The newest GPS block includes M-code, intended to operate through a jammed environment; Lightfoot says enough satellites were on orbit for a globally available M-code signal for warfighters. But receiving that signal requires compatible terminals, algorithms and downstream systems. If the ground equipment cannot receive, interpret and use it, the satellite’s anti-jam capability does not solve the mission problem.

Smoot argues that the commercial sector has an obligation to secure the physical and data links around spacecraft, rather than treating security as a perimeter-defense problem. His starting point is zero-trust architectureA security approach that verifies every user and connection rather than trusting those inside a network perimeter.: every participant in a supply chain or value chain should initially be treated as a potential bad actor unless proven otherwise.

That is a substantial change from legacy systems built around the assumption that anyone inside a firewall is trusted. In a connected supply chain, Smoot says, an attacker can exploit a stolen credential or a weak connection, enter a trusted network and inflict damage from within. A perimeter defense may secure an organization’s edge while failing to secure the relationships and systems operating inside it.

The second requirement is traceability. Knowing a Tier 1 supplier is not enough, Smoot argues. A small electronic component supplied through a Tier 2, Tier 3 or Tier 4 company may affect a satellite’s performance in orbit. Operators need to map that chain backward, identify suppliers’ origins and corporate structures, and establish compliance metrics for participation.

This will require a significant technology upgrade and cooperation with government on regulatory standards and global frameworks. Smoot sees activity in individual functions and sectors, but says the overarching framework that could connect these efforts “quickly and seamlessly” does not yet exist. Companies will need to build reliable, compliant capabilities for the particular parts of the supply chain they serve while coordinating with counterpart firms across the wider system.

The issue is not abstract. Mitchell frames it against recent hospital cyberattacks that forced staff back to manual processes. Space-dependent communications and economic systems could face a comparable reversal if attackers compromise the systems that connect orbital assets to operations on the ground.

The problem is not simply that space is busier. Heather Pringle argues that commercial activity has proliferated faster than norms, regulations and arrangements for managing a congested and contested domain. The 1967 Outer Space Treaty brought more than 100 nations together, she says, but commercial space at the time was limited largely to Intelsat and a small number of other operators. That environment has fundamentally changed.

Pringle places the current space economy at $546 billion and projects it will exceed $1 trillion by the end of the decade. More than 90 space-faring nations operate some form of space asset, she says. Pringle also says deployments have increased roughly fourteenfold in two decades—from a few hundred annually in 2004 to nearly 3,000 operating today.

Commercial activity now accounts for nearly 80 percent of the global space economy, according to Pringle. The speed of that expansion brings capabilities into orbit faster, but it also increases exposure to debris and interference.

Congestion is itself a security hazard. Russia’s 2021 kinetic intercept generated 1,500 large pieces of debris, Pringle says. In low Earth orbit, objects travel about 17,500 miles per hour—nearly three miles a second—and even a tiny fleck of paint can shatter a window on the International Space Station. A debris-producing attack would not merely be a bilateral act against a target; it would impose risks across an orbital environment used by governments, commercial operators and international partners.

Pringle’s prescription is not a claim that international agreement will be easy. Negotiating country by country, with every state having a voice in an international forum, is difficult. But she argues that rules of behavior, dialogue and international cooperation are necessary to keep space secure and peaceful. She identifies the Artemis Accords—then joined by more than 40 nations—as a meaningful early step: a set of roughly 10 principles intended to structure civil cooperation in space.

Bingen makes the more pointed deterrence argument. There are not yet adequate norms in space, she says, and that absence creates a real risk of miscalculation. Maritime and aviation domains offer a precedent: even during the Cold War, adversaries negotiated incidents-at-sea arrangements. The United States can establish and articulate responsible behavior even without meaningful current dialogue with Russia or China.

But a norm without consequences is not deterrence. If a country violates an established standard, Bingen says, the response cannot be merely international disapproval. It must carry economic, diplomatic or some other meaningful consequence.

Kari Bingen portrays China as the more rapidly expanding space competitor. She says China conducted more than 60 launches in the previous year—second behind the United States’ more than 100—and has more than 700 satellites on orbit. Of particular concern, she says, are more than 300 Chinese intelligence, surveillance and reconnaissance satellites.

Those systems give China the ability to observe, track and target U.S. and allied forces in the Indo-Pacific, Bingen argues. Her description is a “transparent ocean”: a theater in which forces that once benefited from distance and concealment can be persistently observed. China also has jammers, interference capabilities, lasers, ground-based missiles and substantial cyber capabilities, she says.

Russia remains highly capable in a different mix of areas. Bingen points to ground capabilities that interfere with satellites and to the war in Ukraine, where Russia has used satellite-communications jamming and GPS interference. She also cites an increasing number of apparent Russian anti-satellite weapons in orbit, likening them to artillery shells able to attack other satellites.

The larger strategic reality is that China and Russia learned from the U.S. use of space-enabled military power. Bingen points to the 1991 Gulf War, where U.S. space capabilities contributed to the rapid defeat of the fourth-largest army in the world. Competitors, she says, have asked how they could deny the United States a similar advantage in a future conflict. Their investments in counterspace are an answer to that question.

Heather Pringle rejects the idea that creating the U.S. Space Force itself improperly militarized a previously benign domain. Space was already heavily militarized, she and Mitchell agree. The case for a dedicated service is that operating and commanding in space demands specialists who understand orbital mechanics, attribution and the distinctive conditions of the domain.

Attribution is especially difficult when assets, services and components are shared across borders. Bingen cites the cyberattack against the Viasat network immediately before Russia’s invasion of Ukraine: it affected Ukrainians, but its spillover also affected German wind turbines and customers across Europe. A space-related attack may not map neatly onto a single country or a single victim.

That interdependence can also strengthen deterrence. Pringle argues that attacking an asset used by the United States and its allies complicates an adversary’s calculation: whom, exactly, has it attacked? Partners can contribute ground sites, antennas, geography and specialized technologies. Bingen sees the U.S. network of allies and partners as an advantage that China and Russia do not share, and argues that expanding partner capacity should be a central element of a strategy to counter China.

A resilient space architecture requires people able to manufacture specialized components, develop software, test systems, interpret data, secure supply chains and integrate commercial capabilities with national-security missions.

Heather Pringle calls talent—not capital—the global space economy’s greatest deficit. Her point is broader than a shortage of aerospace engineers. Space needs artists and communicators as well as orbital-mechanics specialists, scientists and engineers; the challenge is moving people into the capabilities that expanding space enterprises need.

? dan-smoot similarly emphasizes the terrestrial infrastructure behind advanced space programs: manufacturing environments, specialized suppliers and the firms that assemble those contributions into operational systems. Sustaining that ecosystem, he says, requires public and private investment.

Robert Lightfoot sees space as a way to widen the pool of people who see themselves in STEM. Earlier generations were inspired by the 1969 Moon landing, he says; a new generation can see scientists and people outside the traditional test-pilot archetype working and flying in orbit. The limiting question is whether that talent pipeline can keep pace with the systems the sector is trying to build and defend.
