Sadly the censorship ruins it. Other than that, pretty good video.

I wanna say it's Yamato-class, because the battleship in this is absolutely massive, carries a lot of guns and has design features that are strongly reminiscent of the class; but without a full bow to stern panning shot, I really can't say for certain due to how damaged the ship is in the conning tower area. All the shots are either too far away, or too close.

Any ID for the ship?
