§ Mr. Cousins
To ask the Secretary of State for Defence how many nuclear arms capable, or nuclear-powered vessels and submarines of the Royal Navy have been (i) completely scrapped, (ii) are in store or (iii) are in active service at the present time.
§ Mr. Kenneth Carlisle
It is not our practice to define Royal Navy ships as being nuclear-capable or non nuclear-capable. Four nuclear-powered submarines have been taken out of service, and are awaiting final disposal. Of these, one is stored afloat and three are being, or are about to be, decommissioned. There are currently 18 nuclear-powered submarines in service with the Royal Navy.
