James Fisher Defence operates the world’s most comprehensive submarine rescue services - supporting national and international programmes with fast, reliable mobilisation and proven equipment.

We design, manufacture and operate full-system rescue solutions including air-transportable vehicles, launch and recovery systems, hyperbaric reception and transfer under pressure chamber facilities. Our teams also provide training, through-life engineering and real-world operational support at high levels of availability.

In addition to submarine rescue, James Fisher Defence supports military teams with a wider range of subsea solutions - including life support systems and special forces vehicle integration.

Our modular rebreather systems are trusted by defence divers worldwide for their safety, adaptability and endurance - supporting operations from deep mine clearance to shallow covert tasks. We also provide tactical life support, diver vehicle integration and engineered payloads for special forces applications including infrastructure protection and littoral manoeuvre.

We also design and supply certified submarine platform systems - including escape hatches, towers and watertight doors – to navies around the world.

Alongside our defence work, we deliver critical systems, equipment and support services to the global commercial diving industry, helping operators maintain safety and performance in subsea energy, infrastructure and tunnelling operations.

These solutions are underpinned by in-house design, manufacturing and through-life support - ensuring readiness, safety and performance in the world’s harshest operating environments.
