The United States military’s ongoing push to secure a fully domestic defense manufacturing ecosystem has reached a critical milestone, though it underscores deep structural challenges that remain across the broader technological supply chain. The U.S. Army has officially selected Vulcan Elements to supply high-performance rare earth magnets for its ambitious SkyFoundry drone initiative. These specialized magnets are essential components used to power the brushless motors that drive small tactical reconnaissance and operational drones. While Vulcan has confirmed its selection for the high-profile defense program, the company and military officials have not yet disclosed specific order quantities or public delivery schedules.
This major defense award shines a glaring light on the wider vulnerabilities facing U.S. uncrewed aerial vehicle (UAV) manufacturing. Rare earth magnets serve as the critical heartbeat for modern drone propulsion systems, just as advanced battery cells, specialized microelectronics, and proprietary software form the nervous system of contemporary aircraft. As Washington intensifies its legislative and industrial efforts to decouple its defense supply chain from foreign adversaries—most notably China—geopolitical friction has escalated rapidly. Beijing has aggressively tightened its export controls on critical technological materials, enacting sweeping rules that require stringent government licenses for the export of specific rare earth elements and specialized magnets.
The pressure mounted further when trade authorities implemented even stricter regulatory reviews on exports directed toward the United States, targeting listed drones, key mechanical and electrical parts, and associated manufacturing technologies. For the Department of Defense, these geopolitical maneuvers confirm an urgent reality: building millions of tactical drones domestically is impossible without establishing an entirely secure, uninterrupted, and sovereign pipeline for the raw materials and refined components that go inside them.
Production Today and Plans for Expansion
Meeting this unprecedented domestic demand requires massive industrial scaling from the ground up, a challenge that companies like Vulcan Elements are actively racing to address. Vulcan currently produces neodymium iron boron magnets at its initial, small-scale facility located in Durham, North Carolina, which successfully came online in 2025. Recognizing that a localized pilot facility falls orders of magnitude short of national defense requirements, the company is aggressively building a much larger, state-of-the-art manufacturing plant in Benson, North Carolina.
Once fully operational, this upcoming facility is designed to achieve an ambitious annual production capacity of 10,000 metric tons of rare earth magnets. Industry analysts and defense observers note, however, that 10,000 metric tons represents planned maximum capacity rather than current output, and Vulcan has not yet announced a firm calendar date for when the Benson plant will reach its full industrial stride.
Simultaneously, the company is forging a network of domestic feedstock partnerships to secure the underlying rare earth materials necessary for its manufacturing pipeline. Vulcan has established a commercial-scale offtake agreement with ReElement Technologies and has signed a memorandum of understanding with Ucore to build a robust domestic rare earth magnet supply chain firmly on U.S. soil. Ucore has publicly projected that it will begin supplying refined domestic material out of its Louisiana operations by 2027. Furthermore, Vulcan is actively testing and evaluating material sourced from Energy Fuels. Despite these strategic partnerships, the companies have not yet clarified which specific material supplier will feed the production lines fulfilling the newly announced Army award.
What Do the Production Numbers Tell Us?
To understand the magnitude of the industrial hurdle facing the United States, one must examine the sheer scale of the production goals set by programs like SkyFoundry alongside current market realities. Vulcan reports that the SkyFoundry initiative aims to foster the domestic production of one million small drones every single year. To put that staggering figure into some contextual perspective, Federal Aviation Administration data indicates that approximately 424,516 nonrecreational small drones were active across the entire United States civilian airspace in 2025.
The Army program’s stated annual production goal alone is more than twice the size of that entire active civilian fleet estimate. While military tactical attritable drones and civilian commercial aircraft measure entirely different operational metrics and use distinct components, this comparison vividly illustrates the unprecedented industrial scale required to satisfy the Pentagon’s vision.
At present, however, there are no reliable public figures or verified mathematical models indicating exactly how many SkyFoundry drones Vulcan’s current or near-future production capacity can realistically support. Because Vulcan has not disclosed its present baseline annual output, its specific contractual delivery commitments to the Army, or the exact number of magnet units required per individual aircraft, external analysts are left with an incomplete picture.
Compounding the equation is the reality that the planned output from the Benson manufacturing facility will not be dedicated exclusively to the military; it must also service a wide array of commercial customers, electric vehicle manufacturers, and other critical infrastructure industries. These missing operational details will ultimately determine when domestic magnet supply can genuinely synchronize with SkyFoundry’s intended manufacturing velocity.
Even with these lingering questions regarding timelines and capacity bottlenecks, the announcement represents a tangible, highly encouraging step forward in the national effort to onshore the critical defense supply chain. The United States certainly possesses a solid geological foundation upon which to construct this industrial autonomy. According to data published by the U.S. Geological Survey, the nation holds substantial domestic rare earth mineral resources and domestic mines successfully produced an estimated 51,000 metric tons of rare earth oxide in concentrates during 2025.
However, raw mining output alone is fundamentally insufficient to guarantee a secure, resilient defense supply chain. Recovered minerals must undergo complex chemical separation, specialized processing, and advanced metallurgical manufacturing to be transformed into high-grade magnets at scale. Vulcan Elements’ existing facilities and ambitious expansion initiatives represent vital stepping stones toward achieving that complete domestic capability. As these industrial plants mature and the network of material partnerships solidifies, their sustained output will finally provide a clear and reliable timeframe for powering U.S. military engines with authentically American-made parts.
