Fully engaged around the world. Our people operate ships and submarines across every ocean and continent.
Where we operate
Continuous at Sea Deterrent
For 24 hours a day, 365 days a year, Royal Navy Vanguard class submarines patrol the world’s oceans. Their mission? To carry the Trident missile system: the United Kingdom’s strategic nuclear deterrent.
Our long-standing commitment to continuous nuclear deterrence will continue for decades to come when our lethal Dreadnought class ballistic submarines come in to operation in the early 2030s.
