North Sea Tiger - are you sure? I can see no evidence of a radome or any structure protruding from the nose to give a radar a wide field of view.
Crab, it's in the nose, has the same field of view as the current radar on the S61 and the main thing is that it points forwards. So you have a radar which shows what's in front of you rather than whats behind you. Which in my opinion is always an advantage!
