Successor submarine programme: the facts

Chrono Date: 
Tuesday, November 24, 2015

Successor is the replacement programme for the Royal Navy’s Trident missile Vanguard Class submarines which form the UK’s nuclear deterrent.

The continuous at sea deterrent (CASD) has provided the United Kingdom’s ultimate security insurance policy every day for the last 46 years.

Since 1992 the 4 boats of the Vanguard Class have maintained CASD, ensuring at all times 1 submarine was deployed. As the Vanguard submarines progress to the end of their lifespan, the UK is looking at the next generation of submarines to carry forward the vital role.
