The Royal Navy has been operating continuous at-sea deterrent patrols for more than 40 years and the Successor submarines will allow us to do so with cutting-edge equipment well into the future.

Defence Secretary Philip Hammond said:

“This £79 million investment is another important milestone in our preparations to build these world leading submarines.

“The current Vanguard Class of deterrent submarines perform a vital role in the defence of the UK and the replacement for this capability is of national importance.

“The Successor programme is supporting around 2,000 jobs and up to 850 British businesses could benefit from the supply chain as we exploit the most modern technologies, and employ a significant portion of the UK’s engineers, project managers and technicians over the coming years.”

Admiral Sir George Zambellas, First Sea Lord, said:

“The Royal Navy has been operating continuous at-sea deterrent patrols for more than 40 years and the Successor submarines will allow us to do so with cutting-edge equipment well into the future.”

The submarines are being designed to be some of the stealthiest in the world and are expected to see operational service from the late 2020s right up to the 2060s.

The Successor design and build programme is amongst the most complex ever undertaken by British industry.

The total number of MoD and industrial staff currently working on the Successor programme is around 2,000, with more than half working as engineers and designers.

Over 850 potential UK suppliers have so far been identified as benefiting from investment in the programme and as many as 6,000 people will be involved by the time that the construction reaches a peak.
