Small help
(and correct template
)
-rethink the funnels and the hangar: one funnel in the middle, hangar over the whole beam? So you have more space for helos and gear and if you want
you can place an additional RHIB (comes in handy for boarding missions...)
-reduce the height of the hangar a bit (radar signature, top weight?)
-use more "angled" corners (like with the spy/ the Atago for stealth)
-reduce the size of the prop and the rudder (two props? like Atago and more "ground clearance")
For the Spy: AU or not it don't make sence to have 2*180deg. radar if you can have 4*180deg. That means you have full 360deg. cover
and
the other angled superstructure is for stealth reasons, so not a must have but make sence on a stelth ship IMHO
Just look at the other drawings and compare
so you will become better (e.g. shading) and fot technical issues you can ask.
