Whilst I respect your opinion on the 45’s, I can find no sources which agree with your conclusions. I would greatly appreciate some links to sources so i can see how you reached your point of view.
Well, most of my arguments come from known facts. Type 45 IS a large ship. It does not have towed array sonar, nor intrinsic as weapons. It does use lynx and not Merlin. It does have an enormous crew accomodation, in spite of a much smaller crew. Aster is very good, but it doesnt have a great range. These are all known facts.
The conclusion is that considering the size of the thing, and its expense, there isn’t a lot of actual fighting power.
