Core Defence Capabilities

GEL operates from a 330,000 sq ft advanced manufacturing facility in the UK, providing a complete end-to-end solution for defence engineering projects.

Design for Manufacture

We work in close collaboration with defence customers from the early stages of a programme, supporting the development of efficient, manufacturable solutions for mission-critical components. By aligning with customer requirements early, we optimise designs for production, improve scalability, and reduce technical and delivery risk. Our engineering teams provide practical insight into materials, processes, and manufacturing methods, ensuring components are designed for reliability, repeatability, and long-term performance in high-hazard environments.

Manufacture to Specification

GEL delivers precision manufacturing from customer-supplied build-to-print drawings, producing complex, tolerance-critical components to exacting specifications. From initial manufacture through to assembly, testing, and final delivery, we provide a complete, high-assurance solution tailored to defence programme requirements. Our controlled processes, advanced manufacturing technologies, and rigorous quality systems ensure consistent output, full traceability, and compliance with defence and safety-critical standards.
