Integrated underwater capabilities for submarine platforms
We bring together critical capabilities that enable safe, effective and mission‑ready submarine operations. Built around decades of specialist engineering expertise, our offering is structured across three complementary pillars.
Core capability pillars
Escape and rescue interface systems provide proven solutions that support submarine escape and rescue operations, ensuring crew survivability and operational resilience in emergency scenarios.
Ingress and egress at pressure enables the safe transfer of personnel and underwater vehicles into and out of the submarine while submerged. These systems support special forces divers and vehicles, delivering reliable access in the most demanding operational environments.
Environmental management covers the monitoring, control and production of the submarine atmosphere. These systems are essential to sustaining life on board, supporting both submariners and divers through continuous environmental control and health monitoring.
Associated products and services
To support these capabilities, JFD offers a comprehensive range of products and services across the full submarine lifecycle.
This includes submarine design and build, escape towers, watertight doors and hatches, and complete submarine escape and rescue systems.
We also provide commissioning, training and acceptance services, alongside specialist solutions such as Lock‑In/Lock‑Out (LILO) systems, Dry Deck Shelters (DDS), atmosphere and environmental management, health monitoring, and the integration, launch and recovery of TDVs and AUVs.
Together, these solutions position JFD as a trusted partner in delivering safe, capable and future‑ready submarine platforms.
