Modern military systems depend on long and often invisible industrial chains. A fighter aircraft, an air-defense radar, a missile, or a drone may rely on materials extracted, processed, and refined across multiple countries before reaching a production line.
Across North America, Europe, and the Indo-Pacific, governments are now seeking to strengthen the resilience of these supply chains. New mines are being developed, industrial capabilities are being rebuilt, and strategic stockpiles are making a comeback.
The challenge extends far beyond mining itself. Between a rare earth deposit and a weapon system lies an entire industrial ecosystem. Strategic competition is increasingly focused on securing every step of that chain: From mine to missile.
Diversifying supply sources to reduce risk
The first response is to diversify supply sources.
No country can realistically replace China’s position in critical material supply chains on its own. However, several allied nations are developing alternative capabilities designed to reduce the risks associated with excessive concentration.
Australia and Canada are investing heavily in their mining sectors to become trusted suppliers for Western industries. Lithium, rare earths, nickel, and cobalt are among the resources increasingly viewed as essential for both civilian and military technologies.
Europe is pursuing a similar approach. Sweden’s Per Geijer deposit and Norway’s Fen complex are among the most promising projects for strengthening European access to rare earths. None of these projects will transform the global market on their own. Together, however, they contribute to building alternative sources capable of reducing strategic dependencies.
But securing access to resources addresses only part of the challenge. Many of the most significant bottlenecks are located further downstream in the industrial chain.
Rebuilding lost industrial capabilities
Opening a mine does not automatically create strategic resilience. After extraction, critical materials must be concentrated, separated, refined, and transformed before they can be integrated into military systems. Over the past several decades, many of these capabilities became concentrated in China. Western governments are now seeking to rebuild those industrial links.
In the United States, MP Materials has become one of the most visible examples of this effort. The company operates the Mountain Pass mine in California and is progressively developing separation, refining, and permanent magnet manufacturing capabilities with support from the U.S. Department of Defense.
These magnets are used in numerous defense applications, including radars, electronic warfare systems, precision-guided munitions, and advanced naval and aerospace technologies.
Other initiatives follow a similar logic. Lynas is developing rare earth separation capabilities outside China, while Solvay is expanding its processing activities in La Rochelle to support the emergence of a European supply chain
The European Union is supporting these efforts through the Critical Raw Materials Act, which aims to strengthen European extraction, processing, and recycling capacities by 2030
The objective is no longer simply to secure access to materials. It is to rebuild the industrial ecosystem that transforms those resources into military capability.
The return of strategic stockpiles
Even with new mines and expanded industrial capacity, supply chains remain vulnerable to disruption. Conflicts, export restrictions, cyberattacks, or natural disasters can interrupt access to critical materials for months or even years. This is why strategic stockpiles are returning to the forefront.
In the United States, the National Defense Stockpile maintains reserves of materials considered essential for defense production. The objective is not to replace industry but to provide a buffer capable of absorbing temporary shocks.
Japan follows a similar approach through JOGMEC, which combines public reserves and private-sector participation to reduce supply disruption risks. These stockpiles do not eliminate vulnerabilities. They simply buy time.
Why rebuilding a strategic supply chain takes a decade
Time remains the biggest challenge. Critical material supply chains are among the most complex industrial systems to rebuild. Mountain Pass illustrates this reality particularly well.
Even when a mine already exists, every stage required to transform a resource into a usable product must be rebuilt or expanded.
Each stage requires major investment, specialized infrastructure, skilled labor, and regulatory approvals.
Even projects supported by strong political backing can face delays caused by technical, financial, or administrative challenges. The progress achieved by MP Materials demonstrates that rebuilding these capabilities is possible. It also highlights that such efforts require long-term commitment.
This reality explains why governments increasingly view critical material supply chains with the same strategic importance as shipyards, missile factories, or ammunition plants. The challenge facing Western nations is not simply securing access to resources. It is rebuilding the industrial foundations that transform those resources into military capability.
From the United States and Europe to Canada, Australia, and Japan, governments are investing in new mines, processing facilities, strategic stockpiles, and industrial partnerships designed to reduce supply chain vulnerabilities.
These efforts are not aimed at achieving complete self-sufficiency. They are aimed at building resilience. During the post-Cold War era, efficiency and cost optimization shaped global supply chains.
Today, resilience, redundancy, and industrial security are becoming strategic objectives in their own right. Competition over critical materials is therefore no longer simply about resources.
It is increasingly about industrial capacity, processing expertise, and the ability to transform raw materials into military capability. The race for critical materials is ultimately not just a race for mines. It is a race to secure every step of the journey from mine to missile.
