Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what assessment he has made of the effect of the delay in the delivery of HMS Audacious on the cost of extending the service lives of Trafalgar-class submarines.
We do not routinely release planning assumptions for submarine availability as disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces. There are no additional costs over those which are currently planned.
