As set out in the 2015 Strategic Defence and Security Review, we are taking steps to manage the defence nuclear enterprise and ensure the Successor submarines are delivered to time and budget. As part of this, we have established a new Director-General Nuclear to act as single and accountable focal point within the Ministry of Defence for all aspects of the defence nuclear enterprise. We are also establishing a new submarine delivery body for the procurement and in-service support of all nuclear submarines, including the Successor submarines. We have deliberately moved away from a traditional single 'Main Gate' approach, to a staged investment approach with multiple control points. This will enable us to better regulate and control programme funding and delivery.

The rollout of the Successor submarines supports the programme to maintain a Continuous at Sea Deterrent.
