Lessons Learned : The Ryukyu Kingdom disagreement.

Looks like a small heavy cruiser's worth of 203mm secondaries as well. Thats one shiny torpedo magnent.

Somebody loves flying boats.

I would cut the whole thing short, and add wings to the BB.
IRL attempt.

Maddox, don't be showing everyone my TOP SECRET plans!  ;D

But seriously, which tech does Space Battleship Yamato fall under? The tech tree needs to be updated to include "wave motion engines" and "wave motion guns"!

And don't forget the frikin flying-boat on the fantail! It's totally getting built.
