Babcock and Truflo Marine have launched a UK-Australia pilot program under the AUKUS alliance to strengthen submarine industrial capacity.
The initiative will initially focus on manufacturing selected low-complexity submarine valve components at Truflo Marine’s Century Engineering facility in Adelaide.
Over the next 18 months, the parts will undergo UK-led engineering oversight, quality assurance, and validation before potential integration into sustainment support for the Royal Navy’s Astute-class attack submarines.
The pilot is intended to test whether Australian industrial suppliers can be integrated into UK submarine maintenance supply chains as AUKUS partners work to expand shared sustainment capabilities.
Moreover, the effort also aligns with preparations for Submarine Rotational Force-West, the planned rotational deployment of UK and US nuclear-powered submarines in Western Australia, which will require stronger regional maintenance and logistics infrastructure.
It also marks an expanded role for Century Engineering, which recently became the first Australian company to secure US export contracts through the Australian Submarine Supplier Qualification program.
AUKUS Developments
Under the trilateral pact, Australia is expected to build its SSN-AUKUS nuclear-powered attack submarines domestically from the early 2040s, while reactor units will be supplied by the UK.
Washington has also expanded support for the program.
Earlier this year, the US approved a potential $1-billion foreign military sale to support the UK’s AUKUS submarine program.
The package covers technical assistance for the design and development of submarine components and systems.
These include vertical launch systems, weapon launchers, support modules, network hardware, and specialized electronics.
