Highlights

• The Pentagon has requested industry proposals by March 20 for projects to secure supply of 13 critical minerals, with potential funding between $100-$500 million, targeting materials heavily dominated by Chinese production.
• Four rare earth elements—yttrium, samarium, gadolinium, and ytterbium—are critical to defense technologies including jet engines, permanent magnets, nuclear control systems, and high-power lasers.
• This initiative represents a structural shift in U.S. policy from passive reliance on global markets to active industrial strategy, though the real supply chain chokepoint remains downstream processing and magnet manufacturing, not mining.

The U.S. Pentagon has quietly asked industry for proposals to help mine, process, or recycle 13 critical minerals essential for weapons systems, semiconductors, and advanced technologies. The request, reported by Reuters, signals a broader shift: Washington is accelerating efforts to secure supply chains that today depend heavily on China. Several of the materials listed—including yttrium, samarium, gadolinium, and ytterbium—are rare earth elements critical to defense technologies. For investors, the message is clear: defense policy is rapidly becoming a central driver of critical minerals markets.

A Pentagon Shopping List for Strategic Materials

According to reporting by Reuters (opens in a new tab) journalist Ernest Scheyder, the U.S. Department of Defense asked members of the Defense Industrial Base Consortium (DIBC) to submit proposals by March 20 for projects that could strengthen supply of 13 critical minerals.

Potential project funding could range from $100 million to more than $500 million, suggesting Washington is prepared to finance significant industrialcapacity.

The list includes:

• arsenic
• bismuth
• gadolinium
• germanium
• graphite
• hafnium
• nickel
• samarium
• tungsten
• vanadium
• ytterbium
• yttrium
• zirconium

Many of these materials—particularly rare earth elements and tungsten—are heavily dominated by Chinese production or processing, a longstanding vulnerability in the U.S. defense supply chain.

Rare Earths in the Defense Arsenal

Four rare earth elements in the Pentagon’s request deserve particular attention:

Yttrium – used in thermal barrier coatings that allow jet engines and turbines to withstand extreme heat.

Samarium – a key component of samarium-cobalt permanent magnets, which perform reliably in high-temperature defense environments.

Gadolinium –used in nuclear control systems, defense electronics, and specialized alloys.

Ytterbium – important for high-power lasers and advanced sensing technologies.

While these elements rarely dominate headlines like neodymium or dysprosium, they remain critical niche inputs for military technologies.

China remains the largest global producer or processor for many of them, reinforcing the strategic logic behind the Pentagon’s request.

The Supply Chain Reality Check

The Reuters report accurately captures Washington’sconcern about mineral supply risk. However, it leaves out a crucial technical point.

Mining alone does not secure supply chains.

Rare earth and critical mineral ecosystems require:

• chemical separation and refining
• metallization and alloy production
• magnet and component manufacturing

These downstream stages remain heavily concentrated in China, particularly for rare earth magnets.

Industrial Policy Is Now Driving the Market

The Pentagon request fits into a larger pattern of U.S. policy moves aimed at rebuilding mineral supply chains.

Recent initiatives include:

• proposals for a $12 billion strategic minerals stockpile
• Federal investment in companies such as MP Materials
• discussions of an allied critical minerals trading bloc.
• Funding in other supply chain ecosystems, such as ReElement Technologies and USA Rare Earth

Together, these policies signal a structural shift: the United States is moving from passive reliance on global commodity markets to active industrial strategy. While Rare Earth Exchanges™ has suggested far more needs to be done from an industrial policy perspective, the Trump administration, to be fair, has launched more activity in this area than any other administration over the past few decades.

Investor Takeaway

The Reuters reporting is broadly accurate. But it understates the scale of the challenge. The real chokepoint in rare earth supply chains is not mining—it is downstream processing and magnet manufacturing. For investors watching the sector, one conclusion stands out from a Rare Earth Exchanges lens: Defense policy is becoming one of the most powerful forces shaping the future of critical minerals markets.
