COBALT (CO)
CRITICAL RISK
Overview
A hard, heat-resistant transition metal essential to aerospace superalloys, high-performance batteries, and advanced industrial manufacturing. Cobalt is particularly critical for jet turbine blades, military propulsion systems, and high-energy-density battery cathodes used in aerospace and defense applications.
Strategic importance
Cobalt-based superalloys are irreplaceable in jet turbine blades, submarine propulsion systems, nuclear reactors, and advanced aerospace manufacturing. Battery cathodes for military drones, autonomous systems, and electrified combat platforms also depend heavily on cobalt chemistry for energy density and thermal stability.

Strategic impact
Cobalt is deeply embedded in the aerospace and defense-industrial base through both superalloy production and advanced battery systems. A major disruption in cobalt refining or mining would directly impact jet engine manufacturing, submarine propulsion systems, autonomous military platforms, and high-performance battery production. While alternative battery chemistries are emerging, cobalt remains essential for applications requiring maximum energy density, thermal resilience, and operational reliability.
Supply chain control
China
DRC mines much of it, but Chinese firms control major refining and ownership stakes.
Risk indicators
- DRC produces ~70% of global cobalt; Chinese firms control most mines
- Child labor and artisanal mining abuses compound reputational and ESG risk
- Cobalt-free battery chemistries cannot match aviation energy density requirements
Risk & challenge analysis
The Democratic Republic of Congo produces the majority of global cobalt supply, with Chinese state-affiliated firms controlling significant mining ownership, logistics, and refining infrastructure. Political instability, corruption, artisanal mining abuses, and ESG concerns create persistent operational and reputational risk. Although Indonesia is emerging as an alternative supplier, much of its downstream processing remains tied to Chinese industrial infrastructure.
Strategic insight
Cobalt-free battery chemistries such as lithium iron phosphate (LFP) are gaining market share in civilian EVs, but they currently cannot match the energy density requirements necessary for advanced aerospace systems, military drones, and long-range autonomous platforms. Aerospace superalloy demand also remains structurally dependent on cobalt.
