The point is there would always be more than one boat at sea making us less vulnerable to a single lucky? hit. If our Int is so poor we have no notice of an impending strike then we deserve to lose.

You may be right. However, someone with far more knowledge of international affairs than me tells me that if we decommission two Trident warheads for every W80 we activate, there is unlikely to be major objections.
The major problem is will the USA allow us the blueprints for these weapons?
We no longer have any way of testing
