Imperial Roman Navy, 1909 and Earlier Preliminary Pass

[eltf177]

8 - 13.39" / 340 mm 45.0 cal guns - 1,212.54lbs / 550.00kg shells, 100 per gun
     Breech loading guns in turret on barbette mounts, 1907 Model
     4 x Twin mounts on centreline, evenly spread

No superfiring ?

I was just going to ask the same thing... :-[

Its intentional.

[Walter]

So it is kinda like Gangut with the main gun layout but with 4 twin 340 mm turrets instead of 4 triple 305mm turrets, right?

Hmmm... It looks like the design does not love you. :)

Actually quickly comparing, I think it is exactly the same. Might be that you opened the SSR file to check it and not closed it as you worked on correcting the design. The file is still open in the background and when you save it and try to open the SSR file again, you're actually just getting the already open SSR file with the old data back to the foreground.
