But the UKG is considering replacing the Tridents with newer version in the next decade from the US and I have not heard about any issues wrt the MTCR and this sale definately happen AFTER the MTCR is in place!
Only qualms I heard have been about the price to the UK.
It's the submarines that are going to be replaced, not the missiles. The missiles will be in service till 2042, after a life extension program. The Vanguard class subs that carry the trident missiles will need replacement, since they are nearing the end of their service lives.
