Submarine service

Stealth, endurance and flexibility. At the forefront of underwater warfare for over a century.

Under the radar

Silent and secretive. Our submarine fleet plays a powerful role in protecting and defending the high seas.

Using potent torpedoes and precision land-attack missiles, our underwater fleet can seek out and destroy surface vessels, other submarines and land targets - before enemies even know we’re there.

With world-leading tech in our arsenal, we have the freedom to lead national, coalition and nuclear deterrent missions.

Nuclear deterrent

World-leading. Nuclear-powered.

Our Vanguard class submarines - the UK’s strategic nuclear deterrent force - are continually in operation: patrolling the world’s oceans undetected, ready to strike at any time.

Their presence alone sends the most powerful message to anyone who would do us harm. That message will be stronger than ever when our fearsome new breed of submarine, the Dreadnought class, comes in to service.
