Modern military power is typically assessed through its most visible elements—platforms, sensors, and weapons systems. Yet a significant share of that capability depends on far less visible inputs embedded deep within industrial and logistics chains. Specialized industrial gases are among these discreet but structurally critical dependencies.
Helium, xenon, krypton, neon, and nitrogen are not military technologies in themselves. Their role is indirect, but they are essential at multiple critical stages, from manufacturing and maintenance to space operations. This dependency remains largely absent from most strategic assessments, even as it can directly affect the real availability of military capabilities.
A concentrated and hard-to-substitute resource
Helium provides a particularly revealing case. Global production, estimated at roughly 180 million cubic meters, is concentrated in a small number of countries, including the United States, Qatar, Russia, Algeria, and Canada. Data from the U.S. Geological Survey highlights this structural concentration and the vulnerability associated with any localized disruption in production or transport.
This concentration is compounded by the lack of viable substitutes. Helium remains essential for cryogenic applications requiring extremely low temperatures, with no direct alternative under current technological conditions. This does not mean a military would be immediately constrained by supply shortages, but it does introduce friction in specific industrial and technical segments that underpin military capability.
Competition between civilian and industrial uses further intensifies these pressures. Healthcare, research, and semiconductor industries all consume significant volumes, making allocation decisions more complex during periods of market stress.
Rare gases at the core of space and electronic systems
The role of industrial gases extends well beyond helium. Xenon and krypton are directly linked to electric propulsion systems used in satellites to maintain orbit and adjust positioning. Research from the U.S. space sector confirms that Hall-effect thrusters already in operation rely on these gases, establishing a direct link between their availability and space-based capabilities.
This dependency is increasingly relevant as military space systems expand, whether for surveillance, communications, or navigation. The availability of these gases directly shapes the resilience and continuity of those services.
Neon plays a different but equally structural role. It is used in semiconductor manufacturing, which underpins modern electronics. A disruption in neon supply can therefore affect a wide portion of the industrial ecosystem, including defense-related production chains. Analyses from the European Commission’s Joint Research Center confirm the importance of these gases in critical value chains.
These dependencies are not limited to raw resource availability. They also involve purification, distribution, and associated industrial capacities, which are often concentrated among a small number of actors.
Russia as a constraint and a reshaping factor
Russia occupies a distinct position within this ecosystem. It is not just a producer, but a player capable of shaping supply dynamics. Its helium production, estimated at around 17 million cubic meters in 2024, remains below that of leading producers but is part of an expansion trajectory driven by the development of the Amur gas processing complex.
The project is intended to significantly expand production capacity and could alter market balances over the medium term. However, this expansion does not automatically translate into greater availability for European actors, given the geopolitical context and sanctions environment.
For the European Union, the Russian factor reflects a broader dependency. In 2021, nearly half of rare gas imports originated from Russia and Ukraine. This situation combined reliance on a politically sensitive supplier with dependence on an industrial partner weakened by war.
The ban on Russian helium imports, which took effect in 2024, illustrates how dependency has been transformed into a strategic choice. While this decision reduces Russia’s economic leverage, it also constrains sourcing options for European industries in an already concentrated market.
The result is not an immediate rupture, but a reconfiguration of supply flows. Imports are shifting toward other producers, including the United States, Qatar, and Algeria—often at higher cost and with increased competition from civilian demand.
A European dependency still partially structured
The European Union has begun integrating critical gases into its supply security considerations, but this effort remains less advanced than for other resources, such as critical minerals. Vulnerabilities extend beyond resource access to the entire logistical chain, from purification to storage.
This dimension is essential, as it determines the actual availability of gases within industrial systems. Disruptions may occur not at the production level, but in transport, infrastructure, or contractual arrangements. This complexity makes the dependency harder to map and address in policy.
Concrete implications for military capability
The impact of industrial gases on defense is indirect but tangible. In production, they are used in industrial processes, testing environments, and certain advanced technologies. Supply constraints can slow production or force trade-offs between programs.
In sustainment, some systems require controlled environments or specific maintenance procedures involving technical gases. Logistical constraints can therefore affect equipment availability.
At the operational level, space systems, sensors, and electronic architectures depend indirectly on these resources. A prolonged disruption could degrade surveillance, communication, or targeting capabilities.
This reality is already acknowledged within some organizations. The U.S. Defense Logistics Agency manages industrial gas supply for applications related to aviation, missile systems, and space operations, underscoring their role in sustaining military capability.
A logistics framework still taking shape
In response to these constraints, several approaches are emerging, though they remain fragmented. Industrial actors are working to diversify suppliers, secure contracts, and expand storage capacity. Efforts are also underway to develop recycling solutions or technological alternatives where feasible.
However, these initiatives are not always embedded within a coordinated defense policy framework. Critical gases are still often treated as an industrial issue rather than a core component of military resilience.
A discreet constraint at the core of capability
Specialized industrial gases are neither visible nor spectacular. Yet they occupy a central position in the value chains that sustain modern military power. Their importance lies not in volume, but in their role at critical—often invisible—stages.
Russia highlights this reality by acting both as a potential supplier and as a driver of geopolitical realignment. Tensions in these flows do not produce immediate breakdowns, but rather gradual constraints affecting cost, timelines, and availability.
For European actors, the challenge is to turn this largely invisible dependency into an explicit strategic consideration. This requires better mapping of uses, securing supply chains, and integrating these resources into a broader defense-industrial resilience framework.
