Well, the Gotrige "Seacat"(within quotas becouse it's based of the seacat, but has gone through several mods)has somewhat increased range. I'll be thinking over the SAM vs CIWS matter for a bit.
I would like to point out that several IRL navies kept the Seacat even into the 80's, the British flagship during the Falklands War, for example - The HMS
Glamorgan, was carrying the Seacat. So having this ship carrying it would actually be very plausible.
The decks are 15 pixels high - that's about 2,3 m - granted, part of that goes for the actuall floors, but I consider it to be ample. I can increase it one or two pixels if needed be however.
I'll be seeing to the aft hull form... you're right about that one.
That aft 155m gun has been replaced by a Sea Dart comparable system(Not visible on current pic), so no worries there.
I tried more boxy SSM launcher initially, but felt more happy with these.
Hope my reply/explanations was satisfactory.
