The Arctic Critical Minerals Race: How Canada Is Building Resilient Defence Supply Chains
Canada is accelerating efforts to secure access to critical minerals that underpin modern defence systems, as geopolitical competition and supply-chain fragility reshape industrial strategy across NATO. At the center of this shift is molybdenum—a high-performance alloying metal essential to military aviation, naval engineering, missile systems and armoured platforms. Recently, federal support for early-stage development work at Greenland’s Malmbjerg molybdenum project, including a C$7 million contribution through Natural Resources Canada, has highlighted how Ottawa is extending its resource strategy beyond domestic borders into allied Arctic jurisdictions. The initiative reflects a broader policy shift in which critical mineral security is increasingly treated as a matter of national defence readiness rather than purely industrial policy.
Molybdenum and the Backbone of Modern Military Engineering
Although rarely visible in public discussions of defence procurement, molybdenum plays a foundational role in systems that define modern military capability. In aerospace applications, molybdenum is a key element in nickel-based superalloys used in gas turbine engines. These alloys enable fighter aircraft engines to operate under extreme thermal stress while maintaining structural integrity. Components such as turbine blades, combustion chambers and exhaust systems rely on molybdenum-enhanced alloys to resist creep deformation at temperatures exceeding 1,000°C. Within naval propulsion systems, the same metallurgical advantages are equally important. Gas turbines used in modern destroyers and frigates depend on high-temperature alloys capable of sustained performance in corrosive marine environments. As Canada advances long-term naval procurement programs, including next-generation surface combatants, the reliability of these materials becomes central to fleet readiness and lifecycle performance.
Furthermore, in armoured warfare, molybdenum is widely used in high-strength steels for main battle tanks and infantry fighting vehicles. Small additions of the element significantly improve hardenability, toughness and resistance to brittle fracture—properties essential for platforms designed to withstand ballistic impact and explosive shock. Lastly, but most importantly, across missile and rocket systems, molybdenum-containing alloys are also critical. Components exposed to extreme heat during ignition and sustained high-speed flight require materials that maintain dimensional stability under thermal stress, particularly in rocket motor casings, exhaust assemblies and guidance system housings.
Canada’s Defence-Industrial Expansion and Supply Chain Security
Building on these material dependencies, Canada’s increasing focus on defence production capacity is closely linked to its broader industrial strategy. As Ottawa commits to higher defence spending and modernization of air, land and maritime forces, policymakers are emphasizing secure upstream supply chains for critical inputs such as titanium, nickel, cobalt and molybdenum. Rather than relying solely on domestic extraction, Canada is pursuing partnerships with allied jurisdictions to ensure access to strategically important materials. In Greenland, the Malmbjerg project—one of the world’s largest undeveloped primary molybdenum deposits—has emerged as a focal point due to its potential to supply North Atlantic markets under politically aligned governance structures. The C$7 million federal contribution, through this lens, is not only a research investment but also a signal of intent: strengthening allied critical mineral capacity is becoming an extension of defence policy itself.
NATO’s Growing Emphasis On Industrial Resilience
Across NATO, supply-chain security has become a central concern following disruptions in global commodity markets and heightened geopolitical tensions. The alliance, in response, has increasingly emphasized the need for member states to maintain access to secure sources of critical materials required for defence production. Molybdenum, while less publicly discussed than rare earth elements, is essential to sustaining industrial output for platforms ranging from combat aircraft to naval vessels. Its role in high-temperature alloys and structural steels places it at the intersection of aerospace, maritime and land systems engineering. As NATO members expand ammunition production, modernize air fleets and invest in long-range precision strike capabilities, the availability of specialty metals is becoming a limiting factor in industrial scaling. Supply-chain resilience, in turn, has become inseparable from operational readiness.
NORAD Modernization and Arctic Infrastructure
Simultaneously, Canada’s defence modernization plans—including NORAD upgrades and expanded Arctic surveillance capabilities—are increasing demand for advanced materials and complex manufacturing ecosystems. Next-generation radar systems, satellite infrastructure, unmanned platforms and cold-weather operational systems all depend on supply chains that include high-performance alloys and precision-manufactured components. Arctic operating environments further intensify material requirements due to extreme temperatures, corrosion exposure and logistical isolation. Overall, as Arctic shipping routes gradually become more accessible, infrastructure development and domain awareness systems are gaining strategic importance. Consequently, reliable access to critical minerals is becoming indirectly tied to Canada’s ability to sustain surveillance and defence operations across the North.
Greenland’s Strategic Geography
Greenland, from a geopolitical perspective, therefore occupies a pivotal position in the Arctic due to its location between North America and Europe, as well as its substantial untapped mineral potential. Its deposits—including rare earth elements, graphite, zinc and molybdenum—are increasingly viewed through a strategic lens by Western governments seeking to diversify supply chains. Among these, the Malmbjerg deposit stands out due to its scale and quality, making it one of the most significant potential sources of primary molybdenum outside existing dominant producers. Development of such resources aligns with broader allied efforts to build supply networks that are less exposed to geopolitical leverage and concentrated production hubs. In this context, Greenland is not only a resource frontier but also part of a wider Arctic system in which industrial policy, security strategy and geography are becoming tightly interlinked. It is also a strong counterweight to China which remains a major producer and processor of molybdenum and plays an influential role in global critical mineral supply chains.
China’s Role in Global Molybdenum Supply Chains
While the molybdenum market is more diversified than some rare earth segments, China’s significant production share and downstream processing capacity still give it structural influence over pricing and availability. Beijing, in recent years, has expanded export control frameworks covering selected strategic materials, reinforcing perceptions among Western policymakers of potential supply-chain vulnerability. As a result, governments in North America and Europe have increasingly prioritized diversification strategies. Efforts to develop production capacity in allied jurisdictions, alongside domestic investment and joint ventures, consequently reflect a broader shift toward “friend-shored” supply chains intended to reduce exposure to geopolitical disruption.
A Strategic Material in a Strategic Region
Taken together, Arctic geopolitics, defence modernization and industrial policy are converging around materials such as molybdenum, elevating them from niche industrial inputs to strategic enablers of military capability. Canada’s support for Arctic-linked critical mineral development reflects this structural shift. Rather than focusing solely on platforms and procurement, defence planning is increasingly shaped by the resilience of the global supply chains that sustain industrial output. Ultimately, as NATO countries prepare for long-term strategic competition in an increasingly contested international environment, securing access to foundational industrial materials may prove as important as developing the next generation of weapons systems themselves.
