Ultra Dreadnoughts...  See the rant of Paul Timbre before the Industrialists congress.

The design he financed, and will be pushed down parliaments throat.

The HY report 1913 HY1 isn't done yet, so it's possible parliament won't go with it immediatly.

Perhaps Gran Colombia will see if M. Timbre would like to finance a few million mortgages...

Looks like I'll have to use a timewarp to bring my Yamato class BBs to ~1915... :)

I don't think you can put six main gun turrets AND eight 14cm gun mounts on the same level and get adequate firing arcs for the main battery, even if the ship is 270m long.

Interresting study drawing to do.
