United Kingdom
The UK's DragonFire laser DEW program represents the most advanced laser DEW capability in Europe. UKAEA's STEP program, Tokamak Energy, and General Fusion UK constitute a diverse fusion research ecosystem. AUKUS cooperation extends DEW collaboration with the US and Australia.
Key Findings
DragonFire (50-100 kW laser, £316M contract) represents Europe's most advanced laser DEW program, with Royal Navy deployment planned by 2027.
UKAEA's STEP program targets a compact fusion reactor by 2040, with Tokamak Energy's FRC/stellarator development as a commercial complement.
AUKUS DEW cooperation (February 2026) extends the UK's defense technology collaboration with the US and Australia.
61 entities and 71 relationships map the UK's fusion and DEW ecosystem.
No evidence of UK plasma orb weapons development — investment is concentrated in laser DEW and magnetic confinement fusion.
