GALLIUM (GA)
CRITICAL RISK
Overview
A soft metallic element primarily recovered as a byproduct of bauxite and zinc refining. Gallium is essential for gallium nitride (GaN) semiconductors used in high-power radio frequency electronics, radar systems, electronic warfare platforms, and advanced aerospace technologies.
Strategic importance
GaN-based power amplifiers are at the core of every modern fighter radar system including the F-22 APG-77 and F-35 APG-81 AESA radars. Gallium is also critical for electronic warfare systems, directed-energy applications, hypersonic guidance systems, and advanced RF communications. No viable semiconductor alternative currently matches GaN performance at required military power densities.

Strategic impact
Gallium is foundational to advanced RF semiconductor systems enabling modern fighter radar, electronic warfare, hypersonic weapons guidance, and directed-energy systems. A prolonged disruption in gallium refining or export access would directly constrain AESA radar production, advanced semiconductor manufacturing, electronic warfare capabilities, and next-generation aerospace systems. Gallium represents one of the clearest examples of direct overlap between critical minerals and advanced military technological superiority.
Supply chain control
China
Dominates primary gallium production as a bauxite and zinc byproduct and has actively used export controls.
Risk indicators
- China controls ~80% of global gallium production
- Export controls imposed August 2023 — actively disrupting supply chains now
- U.S. stockpiles limited; domestic production nascent and insufficient
Risk & challenge analysis
Gallium is primarily recovered as a byproduct of aluminum and zinc refining, making rapid supply expansion difficult even when strategic demand increases. China's overwhelming dominance in both gallium production and refining enabled the August 2023 export controls that immediately disrupted global semiconductor supply chains. Western efforts to establish alternative gallium refining capacity remain early-stage and insufficient to offset near-term dependence.
Strategic insight
The 2023 gallium export restrictions represented one of the first modern demonstrations of critical mineral leverage directly targeting advanced semiconductor and defense supply chains. Unlike theoretical future vulnerabilities, gallium disruption is already occurring in real time. The combination of limited U.S. stockpiles, immature domestic production, and rapidly growing GaN demand creates an unresolved strategic exposure across advanced military electronics.
