32. Mr. Corbyn

To ask the Secretary of State for Defence what is the current deployment of the Trident submarine fleet. [82611]

Mr. George Robertson

There are currently three Trident submarines in the operational cycle in order to maintain one submarine on deterrent patrol at all times. The UK's minimum deterrent force is maintained at several days' notice to fire as was announced in the Strategic Defence Review.
