What's happened
Countries ramping up military production face supply chain vulnerabilities, especially in rare earth elements and oxidizers like ammonium perchlorate. The US and Germany are investing heavily to boost manufacturing, but reliance on China and limited suppliers pose risks to future military readiness amid rising global tensions.
What's behind the headline?
Critical vulnerabilities threaten global military modernization efforts
The current surge in military orders, including tanks, missiles, and drones, is built on a fragile foundation of raw materials. Germany's reliance on Chinese rare earths like neodymium and dysprosium, essential for modern weapon systems, exposes a significant supply chain risk. Similarly, the US faces bottlenecks in oxidizer production, with ammonium perchlorate (AP) produced predominantly by AMPAC in Utah. Despite recent investments, such as AMPAC's $100 million expansion, scaling these supplies to meet rising demand will take time, leaving potential gaps in military readiness.
The historical context reveals a pattern of consolidation, where the Pentagon favored a 'merger-to-monopoly' approach in the 1990s, reducing competition and creating single-source dependencies. Today, as new entrants challenge these duopolies, the risk of supply chain disruptions increases. The US and Germany are actively investing in domestic manufacturing, but the complexity of certifying high-purity materials and the high standards for safety slow progress.
This situation underscores a broader strategic vulnerability: reliance on limited suppliers for critical materials could hinder rapid military expansion if supply disruptions occur. The push for diversification and domestic production is essential, but it will take years to fully mitigate these risks. In the meantime, the global rearmament effort remains exposed to geopolitical and logistical shocks, which could delay or limit military capabilities in a future conflict.
What the papers say
The articles from Politico, TechCrunch, and Business Insider UK collectively highlight the growing military demand and the supply chain vulnerabilities that underpin it. Politico emphasizes Germany's dependence on Chinese rare earths, crucial for modern warfare systems, and the fragility of these materials. TechCrunch details the US's efforts to expand missile motor production and the bottleneck posed by ammonium perchlorate, a key oxidizer produced mainly by AMPAC, with investments underway to increase capacity. Business Insider UK focuses on the surge in air defense missile production, particularly Patriot systems, driven by global conflicts and rising threats, and the risks posed by limited production capacity and supply chain bottlenecks. While all sources agree on the importance of increasing domestic manufacturing, they also underscore the persistent vulnerabilities due to reliance on limited suppliers and the slow pace of scaling up critical materials, which could impact future military readiness.
How we got here
Recent military rearmament efforts are driven by increased global tensions, including conflicts in Ukraine and the South China Sea. Countries like the US and Germany are expanding their arsenals, but the supply chains for critical materials such as rare earth elements and oxidizers remain fragile. Historically, the defense industry has favored consolidation, reducing competition and increasing dependency on limited suppliers, especially from China, which supplies most rare earths. The US is now investing in domestic production to mitigate these vulnerabilities, but scaling up remains a challenge amid strict certification standards and high demand.
