Strategic Deal to Secure High‑Performance Magnets

Massachusetts‑based ePropelled, a specialist in electric propulsion systems, has signed a joint development agreement with USA Rare Earth to supply neodymium (NdFeB) magnets for advanced drone technology. The move underscores growing U.S. efforts to secure critical materials for aerospace and defense applications while reducing dependence on foreign supply chains.

Announced on Wednesday, the partnership will combine ePropelled’s expertise in high‑efficiency electric motors with USA Rare Earth’s ability to produce domestically sourced rare‑earth magnets. These components are vital for drone propulsion systems, where performance, power density, and weight reduction are critical.

“This agreement is a major step toward reshaping how the U.S. sources and manufactures critical technologies,” said Nick Grewal, CEO of ePropelled. “By working with USA Rare Earth, we can integrate world‑class propulsion design with a secure supply of neodymium magnets — a key ingredient for the next generation of unmanned aerial systems.”

Why Neodymium Magnets Matter

Neodymium‑iron‑boron (NdFeB) magnets are essential to producing high‑power, lightweight electric motors used in drones, aircraft, and electric vehicles. They enable motors to deliver more torque in a smaller package, improving efficiency and extending flight times.

However, over 80% of global neodymium magnet production is controlled by China, creating strategic vulnerabilities for industries that depend on these critical materials. As the U.S. expands its domestic drone manufacturing and defense production, ensuring a secure magnet supply has become a national priority.

“Without reliable access to these materials, American aerospace innovation is at risk,” said Pini Althaus, CEO of USA Rare Earth. “This partnership is about ensuring that vital components of drone technology are made in the U.S. — by U.S. companies — without depending on overseas supply chains.”

Reducing Reliance on Foreign Suppliers

The deal between ePropelled and USA Rare Earth reflects a wider policy shift. The U.S. government has identified rare earth elements as critical minerals and has invested heavily in domestic mining, refining, and magnet production. USA Rare Earth operates facilities aimed at developing a full end‑to‑end rare‑earth supply chain within U.S. borders, from raw material extraction to finished magnet production.

By sourcing magnets domestically, ePropelled can mitigate risks linked to trade disputes, export restrictions, and geopolitical instability. “This is more than a commercial transaction,” said a senior aerospace analyst at Jane’s Defence. “It’s about protecting strategic technologies from external shocks.”

Implications for Drone Technology

For ePropelled, which designs propulsion systems for both commercial and defense drones, access to a stable magnet supply means it can scale production rapidly and meet strict performance requirements. Drones used in military reconnaissance, disaster response, and commercial logistics need motors that are efficient, durable, and capable of sustained operation in harsh environments.

“Neodymium magnets give us the power density to make drones lighter, faster, and longer‑lasting,” Grewal explained. “This translates into better mission endurance, more payload capacity, and greater reliability — all critical factors for our customers.”

As global demand for drones surges, motor and magnet technology has become a differentiator in performance. By controlling both design and key material supply, ePropelled hopes to set a new benchmark in propulsion efficiency.

Aligning With U.S. Industrial Policy

The partnership aligns with Washington’s broader push to onshore production of high‑tech components critical to national security. The Defense Production Act has been invoked in recent years to support domestic mining and processing of rare earth elements, while federal agencies have funded pilot projects for U.S. magnet manufacturing.

“Public policy is creating the conditions for these kinds of agreements,” said Daniel Clifton, a policy strategist at Strategas Research. “Companies are moving fast to secure domestic sources before new regulations or procurement standards make foreign dependence unacceptable.”

The ePropelled‑USA Rare Earth agreement is expected to support this trend by demonstrating that U.S. firms can deliver competitive, high‑performance magnets without relying on Chinese supply chains.

A Boost to U.S. Manufacturing Capacity

USA Rare Earth is developing advanced processing facilities in Texas and Oklahoma that can produce magnets at commercial scale. These sites are designed to handle the entire magnet manufacturing process domestically, from refining rare earth oxide to assembling finished NdFeB products.

For ePropelled, this means its drone propulsion systems will integrate magnets made entirely in America, ensuring quality control and regulatory compliance. “This is the kind of vertical integration the U.S. has lacked for decades,” said Althaus. “We are rebuilding industrial capacity that was offshored years ago.”

Global Competition in Critical Materials

The deal also reflects the global race to control supply chains for critical materials. China has signaled its willingness to limit exports of rare earth products in response to trade tensions, prompting the U.S., Europe, and Japan to accelerate investments in alternative sources.

“Rare earths are the new oil in terms of strategic value,” said Clifton. “Whoever controls production and refining controls the pace of innovation in aerospace, defense, and electric mobility.”

By locking in a U.S.‑made source of neodymium magnets, ePropelled positions itself to weather supply disruptions and maintain production even if global trade becomes more restrictive.

Technical Collaboration and Next Steps

Under the agreement, engineers from both companies will jointly develop optimized magnets tailored to ePropelled’s motor designs. This customization aims to maximize torque and minimize heat generation, improving drone efficiency and reducing maintenance needs.

The first production samples are expected to be tested later this year, with full‑scale manufacturing scheduled for 2026. Commercial and defense drone manufacturers are already in talks to evaluate propulsion units incorporating these domestically produced magnets.

“This is not just about securing materials — it’s about improving performance through co‑design,” Grewal said. “We’re engineering magnets that are made specifically for our propulsion platforms rather than adapting generic components.”

Wider Industry Impact

Analysts say the ePropelled‑USA Rare Earth partnership could inspire similar collaborations in electric vehicles, aerospace, and renewable energy. As electrification accelerates, demand for high‑performance permanent magnets is expected to soar, creating opportunities for vertically integrated supply chains.

“This is a template for how critical material partnerships should work,” said the Jane’s Defence aerospace analyst. “Secure the resource, co‑develop the technology, and build everything at home.”

Other U.S. motor and propulsion system manufacturers may now look to secure similar agreements to avoid potential shortages as global competition for rare earth materials intensifies.

The joint development agreement between ePropelled and USA Rare Earth represents a significant milestone in U.S. efforts to strengthen domestic supply chains for critical technologies. By combining propulsion expertise with a secure source of neodymium magnets, the companies are preparing to deliver high‑performance drone systems that meet both commercial and defense needs.

More broadly, the deal signals that U.S. industry is serious about reducing reliance on foreign suppliers for strategic materials — a shift that could reshape manufacturing in aerospace, defense, and beyond.

As testing begins and production ramps up, the partnership is expected to position both companies as leaders in next‑generation propulsion solutions. “This is about securing the future of American innovation,” Grewal said. “When we control the materials, we control our destiny.”
