Moog and Niron Magnetics are set to demonstrate their innovative rare-earth-free actuator solutions, powered by Niron’s groundbreaking Iron Nitride permanent magnets, at the Association of the United States Army (AUSA) 2026 Annual Meeting and Exposition in Washington, D.C., next October. This collaborative effort aims to revolutionize defense technology by eliminating reliance on geopolitically sensitive rare earth elements, thereby enhancing supply chain resilience for critical military applications such as land vehicles and guided munitions. The showcase at AUSA 2026 represents a significant milestone in a partnership focused on securing vital components for the U.S. Army’s rapidly evolving operational needs.
The Strategic Imperative: Decoupling from Rare Earth Dependency
The modern defense landscape is inextricably linked to advanced materials, none more critical and strategically vulnerable than rare earth elements (REEs). These 17 metallic elements possess unique magnetic, catalytic, and optical properties that are indispensable for a vast array of high-tech applications, ranging from consumer electronics to the most sophisticated military hardware. In the defense sector, REEs are fundamental to precision-guided munitions, advanced radar systems, stealth technology, communication devices, and, crucially, high-performance permanent magnets used in motors and actuators. Without these magnets, many of the Army’s most advanced systems, from the F-35 Joint Strike Fighter to complex land vehicles and drones, would be unable to function as designed.
Jonathan Rowntree, CEO of Niron Magnetics, starkly articulated the current precariousness of this supply chain, stating, "Today almost all of that supply runs through a single foreign source." This "single foreign source" is, unequivocally, China. A comprehensive report from the Council on Foreign Relations (CFR) in October 2025 underscored this alarming dependency, revealing that "China controls up to 90 percent of the world’s critical-mineral processing capacity, including more than 99 percent of processing for three rare earths needed for heat-resistant magnets." These specific rare earths often include Neodymium, Praseodymium, and Dysprosium, which are vital for creating the most powerful and temperature-stable magnets. This near-monopoly grants China significant geopolitical leverage, posing substantial national security risks to nations like the United States, which rely heavily on these materials for their defense industrial base. Any disruption, whether due to political tensions, trade disputes, or natural disasters, could severely cripple military readiness and technological advancement.
Niron Magnetics’ Iron Nitride: A Technological Breakthrough
In response to this critical vulnerability, Niron Magnetics has developed a proprietary Iron Nitride technology that promises to produce high-performance permanent magnets entirely free of rare earth materials. This innovative solution leverages the fundamental properties of iron and nitrogen to create magnetic compounds with strength comparable to, or even exceeding, some traditional rare earth magnets. The process involves introducing nitrogen into an iron lattice structure at a precise atomic level, altering its magnetic characteristics. This development is not merely an incremental improvement but a paradigm shift, offering a direct path to eliminating the problem at its source rather than simply diversifying the supply of rare earths.
Niron claims its Iron Nitride magnets can achieve high magnetic performance without the environmental and geopolitical baggage associated with rare earth mining and processing. Rare earth extraction is notoriously environmentally damaging, involving complex chemical processes that generate toxic waste. By sidestepping this entire chain, Niron’s technology offers a more sustainable and secure alternative. The company has been actively producing Iron Nitride magnets and conducting customer qualification since 2025, demonstrating the technology’s maturity and readiness for real-world applications. Niron anticipates commencing commercial production within the next 18 months, signaling its readiness to scale up and meet market demand. Beyond defense, Niron’s magnets are already finding applications in diverse sectors, including artificial intelligence infrastructure, automotive products, industrial equipment, and consumer electronics, showcasing the technology’s versatility and broad commercial viability.
Moog’s Role: Integrating Innovation into Defense Systems
Moog Inc. brings decades of expertise in designing, manufacturing, and integrating high-performance precision control components and systems for aerospace and defense applications. Known for its sophisticated motion control systems, Moog is a critical supplier for everything from aircraft flight controls to missile steering mechanisms and industrial automation. Their partnership with Niron Magnetics, initially announced in December 2025, focuses on rigorously testing and qualifying Niron’s Iron Nitride permanent magnets specifically within Moog’s electromechanical actuators.
Electromechanical actuators (EMAs) are crucial components in modern defense systems, converting electrical signals into precise mechanical motion. They control everything from the movement of turrets on armored vehicles to the flight surfaces of guided munitions and the positioning of sensor arrays. The performance, reliability, and mass of these actuators directly impact the effectiveness and survivability of military platforms. Ryan Aures, Moog Land and Sea Systems engineering director, underscored the urgency of this collaboration, stating, "The Army is transforming quickly, and the systems soldiers rely on can only move as fast as the supply chains behind them." He further emphasized the strategic objective: "Our work with Niron is about making sure a disruption never stands between the warfighter and the capability they need." This statement highlights Moog’s commitment to ensuring operational readiness and mitigating supply chain vulnerabilities for the U.S. Army. The current focus on land vehicles and guided munitions indicates the immediate high-priority applications for this rare-earth-free technology.
U.S. Government’s Broader Strategy for Critical Minerals
The Moog-Niron project is a critical component of a broader U.S. government strategy to secure and de-risk the supply chains for essential minerals. While the Moog-Niron initiative focuses on developing alternatives that eliminate the need for rare earths, other governmental actions aim to bolster domestic production and processing of these materials. For instance, according to the CFR report, the Department of Defense (DoD) made a significant investment of $400 million in July 2025, acquiring a 15 percent stake in U.S.-based rare-earth producer MP Materials. MP Materials operates the Mountain Pass mine in California, currently the only active rare earth mining and processing facility in North America. This investment, alongside other initiatives like executive orders promoting domestic mining and processing, underscores a dual-pronged approach: enhancing domestic supply where possible, and actively pursuing technological innovations that bypass the dependency altogether.
The Moog-Niron project represents the latter, more revolutionary path. By developing permanent magnets that do not require rare-earth materials, the collaboration offers what could be considered the ultimate "shutdown response" to the entire geopolitical predicament: if the Army just eliminates the need for these minerals, the vulnerability dissipates. This proactive technological bypass offers a more durable solution than simply diversifying or increasing domestic extraction, which still faces environmental, economic, and regulatory hurdles.
The AUSA 2026 Showcase: A Platform for Defense Innovation
