They were introduced in the 1990s as part of the UK’s nuclear deterrent program and are equipped with Trident II D5 ballistic missiles, manufactured in the United States.

Main Features of the Vanguard-Class Submarines:

Type: Nuclear ballistic missile submarines (SSBN) In service: Since 1994 (with HMS Vanguard as the first of the class) Propulsion: Nuclear-powered, enabling extended submerged operation without surfacing for refueling Main Armament: Trident II D5 ballistic missiles, capable of carrying nuclear warheads Nuclear Deterrence Capability: Central to the UK’s nuclear defense strategy, operating under a continuous deterrence principle (one Vanguard submarine is always on patrol)

Importance of the Vanguard-Class Submarines

These submarines form the backbone of the UK’s nuclear deterrence, providing a second-strike nuclear capability in the event of aggression. They are designed for stealthy and submerged operation, remaining at sea for months and being virtually undetectable.

Replacement by the Dreadnought Class

The Vanguard class will be gradually replaced by the new Dreadnought class submarines, currently under construction. These new submarines are expected to enter service in the early 2030s, continuing the UK’s nuclear program.
