Submarine services

50+ years in submarine support, globally

Partnering with the ASC, we play an important role in the ongoing sustainment and future capability of the Collins class submarines through engineering, design, systems integration and platform management capabilities from our engineering and maintenance facilities in South Australia and Western Australia.

We are the manufacturer and maintainer of the Weapons Discharge System and Submerged Signal Ejector (SSE) as well as the in-country repair agent for the Air Purification Unit and Air Turbine Pump. We undertake repair, refurbishment and replacement of key system components throughout the life cycle of its systems.

Internationally, we have supported the UK’s Royal Navy submarine capability for more than 50 years. We sustain the entirety of the Royal Navy’s Vanguard, Trafalgar and Astute Classes including the delivery of through-life support and life extensions.

Babcock manages HMNB Clyde and HMNB Devonport (Plymouth) – two of the UK’s three naval bases – which comprise the operating ports of the Royal Navy’s submarine fleet. These unique facilities enable us to undertake 100% of deep maintenance, in-service maintenance, in-service support and through life management of the UK fleet of nuclear-powered submarines.

We also deliver services for submarine classes in the Unites States, Canada, Spain and South Korea.
