Bravo Zulu! Beautiful ships and very interesting designs!
However, I like several before me in this thread question the arming of the hospital ships.
Under international law (Hague Convention X 1907, Second Geneva Convention 1949, San Remo Manual on International Law Applicable to Armed Conflicts at Sea), a hospital ship cannot claim the protection of a protected symbol (the Red Cross) whilst still remaining armed, as it cannot be "used for any military purpose".
Further, if we to nitpick, in order to be in compliance with the rules of the Geneva Convention, Article 43 states that "All exterior surfaces shall be white. One or more dark red crosses, as large as possible, shall be painted and displayed on each side of the hull and on the horizontal surfaces, so placed as to afford the greatest possible visibility from the sea and from the air."
Excellent work all along, sorry for chiming in that late.
These ships are excellent realistic designs, masterfully executed with a level of detail probably beyond compare among contemporary fictional designs.
Keep up the great job, I'm really looking forward for more of these!
