Whenurhappy,
Oh, and the Norwegian Aegis-fitted vessels are cheap? Well, let's get rid of the Type 45 straightaway!
True, I should, maybe have been somewhat clearer in what I wrote. I was alluding to the Hauk class and Skjold class coastal warfare vessels of the Norwegian Navy along with the Swedish Visby class corvette and vessels like the Triton trimaran.
If you look at paragraph two of my previous posting you will see that I did mention the requirement for deep water vessels. Problem with the Type 45 is that it is hugely expensive (nowt wrong with that if you can afford it) and it is air defence only. We require the anti ship and anti submarine vessels, along with many more big black metal whales, to go with them.
