A revised design, using APAR:
I've added a second radar over the hangar (along with a control window), replaced the directors with CEROS 200 (as a back-up fire control for the guns) and fitted SMART-L as surveillance capability is rather important in an AAW capable vessel! This has necessitated a rearrangement of the turbine exhausts/intakes so instead of a single funnel, the new design has one on each side.
The intakes and exhausts for the forward GTA are very close together and re-ingestion of exhaust gasses is likely.
What if the intakes were located on the sides, as shown, and the exhausts facing aft from the break of the forward superstructure?
Are both electromotors in the same space?
They are mounted symmetrically, yes. If that is likely to be a problem, I could always bring one forward to the compartment between the Gas turbines (also mounted symmetrically) and the GTGs...but I wanted to avoid the complications of long prop shafts.
I don't understand how the lifeboats are arranged.
They are mounted on the sides of the superstructure, just below the deck walk (as on the Burke class).
If that is a door for torpedo tubes in the hull under the hangar then it is very low and will flood very easily, even without damage (rough weather)
Fair point, so I've moved the tubes to the superstructure below the harpoon cannisters.
OK, a good start, a few points:
APAR is a gap-filling (horizon search) and fire control radar, not a volume search radar. If you used APAR you would not need separate illuminators but would loose a lot of surveillance capability - this is why APAR based systems use a separate search radar.
I for some unknown reason completely forgot about APAR and its operational profile
The main reason I went with SPY-1 was to avoid the need for a separate search radar clogging up my topsides! The new arrangement with APAR/SMART-L fits (just about) but in some ways I do still prefer the less cluttered lines of the first draft.
I'm not confident in the extent of my knowledge to attempt the design of an integrated mast, not least because I'd run into the issues of a dedicated volume search radar again.
And yes, this goes with a search radar (Seamaster 400).
I think I'd want something a little meatier than Seamaster!
