User blog comment:I am that guy/Fun Fact: the British 18' gun/@comment-27822411-20160109091232

Woah. Found this old thread.

Point to note, Yamato's guns were actually 18.1 inches, slightly bigger than Furious' 18 inch guns. Though really, the difference is not really major.

I still wouldn't try and sink the Yammmy in that thing though. For obvious reasons.
