Gallium: Why the US Cannot Produce Precision Missiles and Fully-Functional F-35s
TL;DR
The U.S. faces a critical shortage of gallium, essential for precision missiles and F-35s, due to complete reliance on imports from China, which controls 94-98% of global production.
✦ Why It Matters
Evaluate your supply chain for critical materials like gallium to mitigate risks.
Key Takeaways
- Assess your reliance on critical materials like gallium in your projects.
- Explore alternative suppliers for essential components to reduce risk.
- Stay informed about geopolitical developments affecting supply chains.
- Invest in training for engineers in emerging technologies like 6G.
How It Works
Gallium is extracted as a byproduct of bauxite and zinc processing, which China dominates. The U.S. cannot simply start gallium production without first establishing the necessary aluminum and zinc industries, a process that takes over a decade.
