Maritime – Submarines

Our Submarines business has been safely delivering world class submarines to the UK Royal Navy for more than a century.

The Astute class will equip the Royal Navy with its largest and most capable generation of attack submarines. We are responsible for the design, build, test and commissioning of these state-of-the-art vessels. In total, seven boats will make up the fleet, each weighing a mighty 7,400 tonnes.

Dreadnought is the successor to the Vanguard class of nuclear deterrent submarines. We will deliver four submarines to the Royal Navy, with the first submarine entering service in the early 2030s. Dreadnought is widely considered to be one of the world's most complex engineering challenges.
