Re: Spectacular ignorance
You forgot the Zumwalt Class which has a 15.5 cm gun system. Aside from that, I totally agree and I'm a destroyerman with seven years of straight sea time thereon. Having a "real" battleship with, perhaps, some RAP [Rocket Assisted Projectiles] rounds around would be all too the good.
