Company Profile

First Light Fusion is a UK-based technology company delivering high-performance solutions for Aerospace, Space, and Defence applications. Originating from the University of Oxford in 2011, we specialise in systems that simulate and withstand extreme environments, supporting innovation in propulsion, survivability, and advanced materials.

Our capabilities include:
Hypervelocity launch & impact testing – Simulating extreme conditions to validate materials and components under real-world stress.
Pulsed power systems – Compact, modular platforms enabling high-intensity power delivery for propulsion research and weapons development.
Extreme environment simulation – Bespoke platforms for testing resilience, shielding, and system performance in challenging operational scenarios.

We help clients reduce development risk, speed up validation, and avoid the need for capital intensive test infrastructure. Our solutions are built to accelerate innovation and ensure mission critical reliability.

While our long-term goal is to deliver practical, clean fusion energy, the technologies we’ve developed are solving problems today, offering strategic value across the most demanding sectors.

First Light Fusion combines cutting edge science with real world engineering to help clients push the limits of performance, safety, and speed in frontier applications.
