Pentagon Orders 21-Day Weapons Surge-Rare Earths and Germanium Could Be the Chokepoint

Highlights

• Deputy Defense Secretary Feinberg issued a 21-day directive demanding faster weapons production and delivery from major defense suppliers after operations against Iran depleted munitions stocks.
• China's April 2025 export controls on samarium, terbium, dysprosium, and yttrium have created verifiable supply gaps, with no Chinese yttrium shipments to the U.S. reported for two consecutive months by June 2026.
• Germanium, critical for infrared optics and missile guidance, is emerging as a strategic chokepoint, prompting Lockheed Martin to pursue North American supplies from Teck Resources and 5N Plus.
• The Pentagon has sought proposals covering 13 critical minerals including germanium and yttrium, while Washington announced roughly $3 billion in new critical-mineral and battery investments.
• Military readiness now depends on multi-tier industrial supply chains that cannot be surged on command—geology, separation chemistry, and magnet qualification operate on timelines far beyond 21 days.

The Pentagon has given major defense suppliers 21 days to propose faster production and delivery schedules, according to an authenticated August 5 memo from Deputy Defense Secretary Steve Feinberg. The immediate problem is munitions replenishment after sustained operations against Iran. The deeper problem is harder to solve: missiles cannot be manufactured faster than their most constrained materials, components, and production lines. The Trump administration is now attacking both ends of that equation—demanding faster weapons output while committing billions to critical-mineral capacity.

REEx Insight | You Cannot Surge What You Cannot Source

The Feinberg directive is real; some of the surrounding reporting requires more care. Exact classified stockpile levels cannot be independently verified publicly, and the administration disputes characterizations that America is broadly “running out” of munitions. What is verifiable is that Washington is demanding an industrial surge while simultaneously scrambling for the materials required to sustain one.

Rare Earth Exchanges® has been warning about precisely this collision. Our recent analysis, “America’s Empty Magazine Risk: Missiles Meet China’s Mineral Chokepoints,” identified rare-earth magnets, yttrium, and germanium as latent constraints on sustained missile replenishment. Earlier REEx reporting asked whether the mineral problem could ultimately prove harder than the missile shortage itself.

The Factory Has a Periodic Table

China's April 2025 controls cover samarium, terbium, dysprosium, yttrium, and other strategic rare-earth materials. The pressure is no longer theoretical: Rare Earth Exchanges has reported no Chinese yttrium shipments to the United States for two consecutive months by June 2026. USGS separately places terbium, dysprosium, yttrium, and germanium among America's highest-risk mineral supply chains.

Germanium deserves equal attention even though it is not a rare earth. It enables infrared optics and other defense technologies; Lockheed Martin is now pursuing North American germanium supplies from Teck Resources and 5N Plus. Other defense contractors are approaching traders about the specialty mineral. China previously restricted germanium exports, demonstrating how small-volume materials can become enormous strategic chokepoints.

Meanwhile, the Pentagon has sought proposals covering 13 critical minerals, including germanium and yttrium, and Washington just announced another roughly $3 billion of critical-mineral and battery investments.

The 21-Day Paradox

Feinberg is right that years-long acquisition cycles are incompatible with wartime urgency, as we have witnessed in both Ukraine and in the Persian Gulf. But geology, separation chemistry, metallization, magnet qualification, and specialized manufacturing do not obey a 21-day memo. That is the Great Powers Era 2.0 lesson: military power increasingly rests upon industrial networks buried several tiers beneath the prime contractor. The real readiness metric is therefore not how many missiles Washington orders. It is whether every irreplaceable material and component exists when the production line asks for it. Yes, America can order a weapons surge overnight. It cannot order a supply chain into existence overnight.
