Dr Thérèse Coffey (Suffolk Coastal) (Con)
16. What estimate he has made of the minimum number of submarines required to maintain a continuous-at-sea nuclear deterrent.
John Howell (Henley) (Con)
17. What assessment he has made of the potential effect that a reduced number of nuclear-armed submarines would have on the UK’s ability to maintain a continuous-at-sea deterrent.
The Secretary of State for Defence (Mr Philip Hammond)
The 2006 White Paper, “The Future of the United Kingdom’s Nuclear Deterrent”, stated that the minimum number of Vanguard class submarines required to maintain a continuous-at-sea nuclear deterrent was four. The number of submarines required to deliver CASD into the future will be determined in the main gate investment decision for the successor replacement for the Vanguard class, which is expected in 2016. This is a technical, rather than a policy, question.
