Defense electronics
Trusted fabs, RF components, and rare-earth magnets behind missiles, radar, and avionics.
⚠ Trusted foundry & gallium supply
Key chokepoints
- Trusted foundry & ASIC fabSemiconductors
U.S. trusted foundry capacity is limited; CHIPS Act funding targets on-shore advanced packaging.
Related tickers: LMT, RTX
- Rad-hard packaging & testPackaging
Qualified packaging lines are scarce; lead times stretch during procurement surges.
- GaN / GaAs RF componentsRF electronics
Gallium refining is concentrated in China; DoD stockpiling programs address shortfalls.
- Rare-earth magnets (precision guidance)Materials
Non-Chinese magnet supply chains are still ramping; MP Materials and downstream partners are key.
