The review reduced operational launch tubes from 12 to eight and warheads from 48 to 40. It forecast savings of 750 million pounds during the spending-review period and 3.2 billion pounds over ten years. The claimed disarmament benefit is challenged on the grounds that Britain's reductions did not persuade other nuclear powers to follow. A further concern is that the cuts may have weakened perceptions of Britain's deterrent credibility and thereby made the world less secure.
