As for trident bin it and adapt what we have already ie tomahawk system or maybe a couple of stealth bombers from the yanks surely going to bemcheapermeasiermand amdamn site quicker into service
Is it not true that the nuclear version of tomahawk has been withdrawn from US service as the result of a treaty with the Russians? Either way we would have to develop our own warhead if we want our nuclear deterent to remain independant of the US which would cost a fortune.
Plane launched missiles are not a good idea for the UK's strategic deterenent as our island is too small and we would no longer be in a postion to threaten our enemies with MAD. Besides which the US would not sell US would not sell us stealth bombers we maybe one of their strongest allies but certain technology is not for export!
