Hearing Analysis
Overview
The Senate Armed Services Committee met on February 24, 2026, to address the strategic vulnerabilities created by the United States' reliance on the People's Republic of China (China) for critical minerals. Chairman Roger F. Wicker (R-MS) opened the hearing by highlighting that China currently controls over 70 percent of rare earth imports and 60 percent of antimony, materials essential for advanced weaponry and the civilian economy. He noted that recent export threats from Chinese leader Xi Jinping underscored the urgent need to rebuild domestic supply chains, a process estimated to take over a decade. Ranking Member Jack Reed (D-RI) concurred on the threat but raised significant concerns regarding the Department of Defense (DOD) strategy of taking equity stakes in private companies, questioning the legal authority and market impacts of such interventions.
Key Testimony
The witnesses, Michael P. Cadenazzi, Jr., Assistant Secretary of Defense for Industrial Base Policy, and Jeffrey Frankston, Acting Deputy Assistant Secretary of Defense for Industrial Base Resilience, outlined a four-pillar strategy to reclaim mineral independence. This strategy includes reshoring production, "friend-shoring" with allies, interagency cooperation, and strengthening the National Defense Stockpile. Cadenazzi testified that China controls 95 percent of global heavy rare earth output, allowing Beijing to weaponize supply chains. To counter this, the DOD is utilizing $5 billion appropriated through the "One Big Beautiful Bill Act" and authorities under Title III of the Defense Production Act (DPA) to catalyze domestic mining and refining.
Policy Proposals
A central point of discussion was the DOD’s recent $400 million investment to acquire a 15 percent equity stake in MP Materials Corp. (MP Materials). Cadenazzi defended the move as a necessary catalyst for private investment in a "failed market" manipulated by Chinese pricing. However, Sen. Reed and Sen. Mazie K. Hirono (D-HI) questioned whether the DPA actually authorizes equity purchases, noting that the Office of Management and Budget (OMB) has since requested explicit legislative authority for such deals. Sen. Reed also expressed concern over a 10-year price floor agreement for magnets with MP Materials, suggesting it might disadvantage other domestic producers.
Overview
The hearing also highlighted the role of international partners. The DOD has secured deals with the Commonwealth of Australia (Australia), the Federative Republic of Brazil (Brazil), and the Kingdom of Saudi Arabia (Saudi Arabia) for mining and refining. Specifically, a trilateral investment involving Alcoa Corporation (Alcoa) and Japan was mentioned, along with a deal with Ma'aden in Saudi Arabia. Domestically, the witnesses cited investments in Korea Zinc Co., Ltd. (Korea Zinc) for a U.S.-based smelter and a consortium involving Vulcan Energy Resources (Vulcan), Re-Element Technologies (Re-Element), and Corning Inc. (Corning) for magnet production.
Partisan Dynamics
Partisan friction emerged regarding environmental regulations and permitting. Sen. Dan Sullivan (R-AK) criticized the "last frontier lockup," arguing that 70 executive orders from the previous administration hindered mining in Alaska, which contains 56 of the 60 minerals the U.S. requires. He advocated for major NEPA permitting reform. In contrast, Sen. Hirono and Sen. Jeanne Shaheen (D-NH) emphasized that environmental protections must not be discarded, with Sen. Hirono specifically opposing mining near Minnesota’s Boundary Waters.
Industry Impact
The semiconductor sector was also addressed. Sen. Mark Kelly (D-AZ) questioned why major DOD programs continue to rely on outdated "trusted foundries" rather than leading-edge chips produced through the Secure Enclave or Microelectronics Commons programs. Cadenazzi attributed this to high certification costs and the lack of incentives for programs to migrate to new architectures.
Notable Exchanges
In a notable exchange, Sen. Elizabeth Warren (D-MA) attacked the performance of major defense contractors, including Northrop Grumman Corporation (Northrop Grumman), Raytheon Technologies (Raytheon), and General Dynamics Corporation (General Dynamics). She cited a Government Accountability Office (GAO) report finding $50 billion in cost overruns and criticized these firms for spending billions on stock buybacks and executive compensation while failing to deliver systems on time. Cadenazzi agreed that contractor performance has been "unsatisfactory" and expressed a willingness to work with Congress to give more "teeth" to executive orders prohibiting buybacks for failing contractors.
Overview
Regarding next steps, the DOD committed to providing the committee with term sheets for the MP Materials deal and a legal opinion from the Office of General Counsel regarding equity investments. Additionally, the Defense Logistics Agency (DLA) is expected to submit a report by March 1, 2026, on best practices for strategic material recovery and recycling, a sector Cadenazzi identified as a critical long-term source of supply.
