The 2027 Defense Deadline That is Forcing the U.S. to Rebuild 40 Years of Lost Tech

Estimated reading time: 5 minutes

Roughly 40 years ago, the United States made a decision that seemed perfectly rational at the time: it stopped processing rare earths. The economics didn't make sense when China could do it cheaper, so U.S. facilities closed…the expertise scattered…and an entire layer of industrial capability mostly disappeared from North American soil.   Companies mentioned in today's commentary includes:  Realloys Inc. (ALOY), MP Materials Corp, USA Rare Earth Inc., Energy Fuels Inc. Perpetua Resources Corp., Comstock Inc.

REalloys (ALOY) is the company now working to undo the four decades of neglect that have followed…and the reason it matters is that the expertise it holds may be the single hardest thing in the rare earth supply chain to replace.

In fact, the Center for Strategic and International Studies has identified rare earth metallization and alloying as the least developed and most difficult capability to rebuild outside China. According to CSIS, this kind of expertise is learned over long operating histories, not built on a schedule. It's the kind of expertise that can only be built through years of doing it…and no amount of money can speed that up.

How America Lost Control of a Critical Industrial CapabilityThe West didn't lose its rare earth processing capability to espionage or theft. It lost it to economics. Starting in the 1980s and accelerating through the 1990s, China made a deliberate decision to invest heavily in rare earth mining and processing. State support absorbed losses, environmental controls were minimal, and labor was cheap. The result was a production cost that no Western facility could match. One by one, processing operations across North America and Europe shut down. The last major U.S. rare earth mine, Mountain Pass in California, closed in 2002.

But what disappeared was far more than a few facilities. The people who knew how to run them retired or moved on, and the specialized equipment was decommissioned. The institutional knowledge of how to separate 17 individual rare earth elements, how to convert oxides into metals at extreme temperatures, and how to alloy those metals to exact specifications for defense and industrial use…well, that accumulated expertise simply ceased to exist in the West.

As one rare earth processing expert put it bluntly: the West abdicated its rare earth processing capability to China. The skillsets, the workforce, the equipment, and the process knowledge are now 30 years behind, and none of it can be developed overnight.

China understood the value of what it was accumulating. While Western companies optimized for short-term profitability, China was playing a longer game, building deep process knowledge, training specialized workforces, and integrating downstream into metals, alloys, magnets, and finished components. By the time anyone in the West noticed how dependent they'd become, China controlled approximately 90–95% of global rare earth processing and an even larger share of finished magnet production.

No Amount of Money Can Replace 40 Years of Knowledge

Converting rare earth minerals into defense-grade metals and alloys is an extraordinarily complex industrial process. It involves separating 17 individual rare earth elements through multi-stage solvent extraction…then converting purified oxides into metals at temperatures exceeding 1,200 degrees…then precision alloying to exact specifications across thousands of individual micro-steps…and all of this must be controlled with extreme precision.

Each stage requires specialized knowledge that can only be built through years of hands-on operation. There are no textbooks that teach it. There are no consultants who can install it. It has to be learned by doing, failing, adjusting, and doing it again over years and years.

The SRC facility in Saskatchewan, built by REalloys' processing partner, illustrates just how steep the learning curve is. When China blocked the export of processing technology in 2020, SRC had to design and build its own systems from scratch.

It took years of work by a multidisciplinary team of mineral experts, processing specialists, and AI engineers working in concert. The AI system alone was trained by deliberately breaking the separation process over and over for months until it ran out of problems to solve.

Even with SRC's 15 years of prior experience working with rare earth clients, it still took years to get to where they are today, which is producing higher-purity metals with six people and an AI system, compared to the 80 workers a comparable Chinese facility would require.

The Company That Kept the Expertise Alive

Through its acquisition of PMT Critical Metals, REalloys (ALOY) took ownership of the Euclid, Ohio, facility along with more than 30 years of applied development in specialty metals processing. That includes eight years of focused work on rare earth metallization in collaboration with U.S. national laboratories and the Defense Logistics Agency, which is work that involved thousands of production runs, failed experiments, and iterative redesigns carried out in operating facilities rather than academic labs.

The Euclid facility is currently the only site in North America with a proven track record of delivering rare earth metals and alloys to government and commercial partners.

It already holds contracts with the U.S. Department of Defense, Department of Energy, and NASA. And the processes it uses have been demonstrated, tested, and qualified under real-world conditions, which is what separates operational expertise from a business plan.

Andrew Sherman, REalloys' Head of Research and Development, describes the Euclid facility as a platform the company can build from rather than something it has to invent. The remaining work, he says, is about expanding capacity and locking in long-duration defense programs where material supply is committed for years. The hardest part, which is proving the process works, has already been done.

That distinction is critical. Defense and industrial customers qualify processes and the people and facilities behind them, not technologies on paper. Qualification can take several years, and once a supplier is locked in, switching becomes a technical and regulatory undertaking that nobody takes on willingly. A company starting from scratch today would need to build the expertise, prove the process, and then spend years getting qualified…all while REalloys is already delivering.

Expertise Backed by a Complete Supply Chain

Upstream, the company owns the Hoidas Lake rare earth project in Saskatchewan and has secured feedstock agreements with partners in Kazakhstan, Brazil, and Greenland. Midstream, it holds an exclusive 80% offtake on production from the Saskatchewan Research Council's Rare Earth Processing Facility in Saskatoon, targeting first commercial production in late 2026 to early 2027. Downstream, the Euclid facility will handle the metallization, alloying, and magnet manufacturing that defense and industrial customers actually need.

By early 2027, the combined platform is expected to produce approximately 525 tonnes per year of neodymium-praseodymium metal, roughly 30 tonnes of dysprosium oxide, and 10 tonnes of terbium oxide. At that scale, the SRC facility would be the largest source of heavy rare earth oxides outside China, sitting right in North America's backyard.

Phase 2 plans call for significantly larger production later this decade, including approximately 200 tonnes per year of dysprosium metal, 45 tonnes of terbium metal, with capacity to produce up to 20,000 tonnes per year of heavy rare earth permanent magnets.

That timing is critically important, as on January 1, 2027, updated U.S. defense procurement rules under DFARS take effect that will restrict the use of Chinese-origin rare earth materials in qualifying weapons systems. That creates immediate, government-mandated demand for domestically processed, defense-compliant material, which is exactly what REalloys' Euclid facility has spent 40 years learning to produce.

The institutional support behind REalloys reflects the seriousness of the undertaking. The U.S. Export-Import Bank has issued a $200 million letter of intent to support the company's supply chain development.
