Re: Well, its good to see the QE going out to sea.
'Some of the time.'
Well yes, no ones yet invented an infallible missile, or anything else yet which is why you tend to go for defence in depth.
Interestingly it turns out 48 missiles is significantly more than any of the air defence ships in the Falklands conflict fired. Of course if something like you suggest happened in the Gulf I suspect a large number of TLAM would be en-route to the source before they got close to launching 50.
