Pentagon officials testify on critical minerals equity investments and China dependence

Purpose

The Senate Armed Services Committee convened this hearing to examine the state of America's critical minerals supply chains and the Department of War's strategy for reducing reliance on China, which supplies about 70% of U.S. rare earths▶ 0:17:17 and 95% of global rare earth output▶ 0:30:11. Two Pentagon officials, Michael Cadenazzi (Assistant Secretary for War) and Jeff Frankston (Acting Deputy Assistant Secretary of Defense), testified about equity investments, price floor deals, the National Defense Stockpile, and recycling programs, while senators from both parties pressed on the legal basis for the Pentagon's equity stakes in mining companies. Begins at▶ 0:16:21

Who spoke

• Chair Roger Wicker (R-MS)▶ 0:16:21: Opened by warning that reliance on Chinese critical minerals is a major strategic vulnerability, noting China twice threatened to cut off rare earth exports last year▶ 0:16:21; later pressed Cadenazzi on how the U.S. fell so far behind▶ 0:38:37 and on equity investments as a strategy▶ 0:40:53.

• Sec. Michael Cadenazzi, Assistant Secretary for War (Industrial Base Policy)▶ 0:18:53: Outlined four pillars of the Pentagon's strategy—onshoring, allied supply chains, R&D substitution, and stockpile modernization▶ 0:31:31; cited $5 billion for the Industrial Base Fund and $2 billion for the stockpile from last year's reconciliation bill▶ 0:19:52, and deals with MP Materials, Corning, and Elements USA▶ 0:20:19; defended equity investments as necessary given a "failed marketplace approach"▶ 0:41:18 and said the goal is not financial return but taxpayer-repaid outcomes▶ 1:22:38.

• Mr. Jeffrey Frankston, Acting Deputy Assistant Secretary of Defense▶ 0:36:39: Emphasized interagency cooperation and stockpile oversight▶ 0:36:55; described building supply chain maps for each critical mineral from raw material to finished product▶ 0:58:57; noted recent hires bolstering his team's mineral expertise▶ 1:26:27.

• Sen. Jack Reed (D-RI), Ranking Member▶ 0:24:00: Questioned the legal basis for DOD's equity investments, saying the Defense Production Act doesn't explicitly authorize equity purchases▶ 0:26:24; flagged the $110/kg, 10-year MP Materials magnet price deal as undisclosed in rationale and duration▶ 0:27:21; pressed on Antideficiency Act compliance for future appropriations reliance▶ 0:48:00 and on shareholder-vs-government-agent legal distinctions▶ 1:24:19.

• Sen. Dan Sullivan (R-AK)▶ 0:48:44: Argued Democratic-aligned environmental opposition has blocked Alaska mining, citing USGS findings that Alaska holds 56 of 60 needed critical minerals▶ 0:49:58 and the Ambler Mining District fight▶ 0:50:55; pressed on permitting reform▶ 0:52:23 and small business/mentor-protege programs▶ 0:53:46.

• Sen. Jeanne Shaheen (D-NH)▶ 0:55:00: Objected to Sullivan's partisan framing▶ 0:55:00; pressed Cadenazzi for clear criteria on equity investment decisions▶ 0:55:56 and whether DOD is investing in processing versus extraction, noting China's processing dominance is the core issue▶ 0:58:32.

• Sen. Tim Kaine (D-VA)▶ 1:00:49: Countered that Democrats have long supported permitting reform but that the administration's fight against offshore wind has stalled bipartisan progress▶ 1:01:11; asked how DOD is helping Australia scale lithium refining▶ 1:02:09 and about battery sourcing requirements for the Drone Dominance program▶ 1:05:16.

• Sen. Mark Kelly (D-AZ)▶ 1:06:38: Pressed on semiconductor supply chains, asking why DOD programs still use outdated foundries instead of funded "Secure Enclave" and "Commons" alternatives▶ 1:08:12, and what would speed migration▶ 1:11:18.

• Sen. Mazie Hirono (D-HI)▶ 1:11:40: Raised opposition to reversing the Minnesota Boundary Waters mining ban▶ 1:12:02 and questioned the legal authority behind DOD's ~$400 million equity stakes▶ 1:12:33; pressed on recycling progress, citing the DLA germanium recycling program▶ 1:14:57, and asked about a March 1, 2026 NDAA-mandated report deadline▶ 1:16:34.

• Sen. Jim Banks (R-IN)▶ 1:17:41: Asked Cadenazzi to explain the unique value of equity stakes versus other financing tools▶ 1:17:41 and about consequences of China's October rare earth export controls▶ 1:20:32.

• Sen. Elizabeth Warren (D-MA)▶ 1:27:22: Cited GAO findings that DOD's major weapons programs were 18 months behind schedule and $50 billion over budget in FY2024▶ 1:27:51, listing Northrop Grumman's Sentinel program as $36 billion over budget▶ 1:28:21; contrasted this with $3 billion in stock buybacks/dividends by Raytheon, General Dynamics, and Northrop Grumman and CEO pay of up to $24 million▶ 1:30:23, and pressed for legislation to codify an executive order restricting buybacks for underperforming contractors▶ 1:32:23.

Key moments

• China controls 95% of global rare earth output while the U.S. imports almost 100% of what it uses, 90% from China, per Cadenazzi▶ 0:30:11.

• Reed questioned the legal basis for DOD's equity investments, noting the administration's own budget office has requested legislation to explicitly authorize equity investment—suggesting DOD recognizes current authority is uncertain▶ 0:26:51.

• The Pentagon's MP Materials deal locks in a $110/kg magnet price for 10 years starting 2028; Reed said the committee has received no explanation for how the price or duration were set, and other domestic producers say it undermines their competitiveness▶ 0:27:21.

• Sullivan said Alaska holds 56 of the 60 critical minerals the U.S. needs per USGS, and blamed "far left" opposition for blocking the Ambler Mining District road, which the committee approved 21-6 before Democratic leadership stripped the provision▶ 0:50:55▶ 0:51:21.

• Cadenazzi acknowledged the U.S. has "been trying consistently the last 10-15 years" without success, and that current dependence on China for rare earths "is significantly high"▶ 0:41:45.

• Cadenazzi confirmed the Pentagon has taken equity stakes in critical mineral companies, comparable to a precedent from the 2008 financial crisis, and said the goal is improved mineral production rather than financial return▶ 1:19:16▶ 0:41:18.

• Warren cited GAO data that DOD's major weapons programs were 18 months late and $50 billion over budget in FY2024, including Northrop Grumman's Sentinel program at $36 billion over, while contractors spent $3 billion each on buybacks/dividends and paid CEOs up to $24 million▶ 1:27:51▶ 1:28:21▶ 1:30:23.

• Kaine noted Australia produces about half the world's lithium but has historically relied on Chinese refining; Cadenazzi responded that lithium is "not on our critical list" and doesn't require much DOD focus▶ 1:02:54.

• Hirono raised the roughly $400 million in DOD equity stakes and asked what would happen if the underlying legal authority were found not to exist, referencing the Supreme Court's tariff ruling▶ 1:12:33▶ 1:13:51.

• Kelly asked why DOD's funded "Secure Enclave" semiconductor alternative isn't being used by major programs still relying on outdated chip foundries; Cadenazzi cited cost and requalification burdens as the barrier▶ 1:08:12▶ 1:09:59.
