Nuclear Submarines

Volume 498: debated on Monday 2 November 2009

To ask the Secretary of State for Defence what his policy is on a future fourth submarine for the next generation of the nuclear deterrent. (296631)

The 2006 White Paper (Cm 6994) said that if it is technically possible to deliver Continuous At Sea Deterrence, the policy of having one nuclear-armed submarine on patrol at all times, with three submarines then we would do so. The Prime Minister has asked for a report on this by the end of the year. The UK remains committed to Continuous At Sea Deterrence which is the backbone of our deterrence posture, ensuring a credible and capable deterrent against blackmail and acts of aggression against the UK's vital interests including her NATO allies by nuclear-armed opponents. Continuous At Sea Deterrence is the UK's most enduring current operation and has been successfully delivered for over 40 years by our dedicated service personnel.
