We design, build, test, and commission the most advanced submarines ever operated by the Royal Navy, as well as their state of the art combat systems and equipment.
With our main base in Barrow we also operate satellite sites around the UK employing around 13,500 people and working closely with a wide range of suppliers.
With a proud history we are currently working on the Astute and Dreadnought class submarines for the Royal Navy.
We have also signed a tasking statement with the Australian Submarine Agency (ASA) and ASC Pty Ltd, to support the delivery of the SSN AUKUS fleet of conventionally armed, nuclear-powered submarines for the Royal Australian Navy.
Our people
We employ nearly 10,000 people supported by a supply chain of many thousands more.
