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 earths0:17:17 and 95% of global rare earth output0:30:11. 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 at0:16:21

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 year0:16:21; later pressed Cadenazzi on how the U.S. fell so far behind0:38:37 and on equity investments as a strategy0:40:53.

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 modernization0:31:31; cited $5 billion for the Industrial Base Fund and $2 billion for the stockpile from last year's reconciliation bill0:19:52, and deals with MP Materials, Corning, and Elements USA0:20:19; defended equity investments as necessary given a "failed marketplace approach"0:41:18 and said the goal is not financial return but taxpayer-repaid outcomes1:22:38.

Mr. Jeffrey Frankston, Acting Deputy Assistant Secretary of Defense0:36:39: Emphasized interagency cooperation and stockpile oversight0:36:55; described building supply chain maps for each critical mineral from raw material to finished product0:58:57; noted recent hires bolstering his team's mineral expertise1:26:27.

Sen. Jack Reed (D-RI), Ranking Member0:24:00: Questioned the legal basis for DOD's equity investments, saying the Defense Production Act doesn't explicitly authorize equity purchases0:26:24; flagged the $110/kg, 10-year MP Materials magnet price deal as undisclosed in rationale and duration0:27:21; pressed on Antideficiency Act compliance for future appropriations reliance0:48:00 and on shareholder-vs-government-agent legal distinctions1:24:19.

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 minerals0:49:58 and the Ambler Mining District fight0:50:55; pressed on permitting reform0:52:23 and small business/mentor-protege programs0:53:46.

Sen. Jeanne Shaheen (D-NH)0:55:00: Objected to Sullivan's partisan framing0:55:00; pressed Cadenazzi for clear criteria on equity investment decisions0:55:56 and whether DOD is investing in processing versus extraction, noting China's processing dominance is the core issue0:58:32.

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 progress1:01:11; asked how DOD is helping Australia scale lithium refining1:02:09 and about battery sourcing requirements for the Drone Dominance program1:05:16.

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" alternatives1:08:12, and what would speed migration1:11:18.

Sen. Mazie Hirono (D-HI)1:11:40: Raised opposition to reversing the Minnesota Boundary Waters mining ban1:12:02 and questioned the legal authority behind DOD's ~$400 million equity stakes1:12:33; pressed on recycling progress, citing the DLA germanium recycling program1:14:57, and asked about a March 1, 2026 NDAA-mandated report deadline1:16:34.

Sen. Jim Banks (R-IN)1:17:41: Asked Cadenazzi to explain the unique value of equity stakes versus other financing tools1:17:41 and about consequences of China's October rare earth export controls1:20:32.

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 FY20241:27:51, listing Northrop Grumman's Sentinel program as $36 billion over budget1:28:21; contrasted this with $3 billion in stock buybacks/dividends by Raytheon, General Dynamics, and Northrop Grumman and CEO pay of up to $24 million1:30:23, and pressed for legislation to codify an executive order restricting buybacks for underperforming contractors1:32:23.

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 Cadenazzi0:30:11.

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 uncertain0:26:51.

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 competitiveness0:27:21.

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 provision0:50:550:51:21.

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 return1:19:160:41:18.

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 million1:27:511:28:211:30:23.

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 focus1:02:54.

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 ruling1:12:331:13:51.

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 barrier1:08:121:09:59.
