Des Browne
The White Paper (CM 6994) on the future of the UK's nuclear deterrent published on4 December set out (at paragraph 5-3 and 5-4, Box 5-1 and Annex B, paragraph 6) our assessment of the effectiveness of a nuclear deterrent based on cruise missiles. We concluded that, in terms of both cost and capability, retaining the Trident D5 ballistic missile is by far the best approach.
