Which means that Yamato wouldn't get into krishima's position is enough. Considering how Kirishima fired at damaged warship with all its brute scoring multiple hits but not penatrating a single armour plate. The difference was kirishima was unprepared. As if it was ambushed. But either ways your comment was really informative.
My point, since you seem to have missed it, was that while Yamato's radar was sufficient to give warning, it was not sufficient to lay its guns, meaning it still needs fair weather in daylight to actually lay its guns well.
As for the turning-radius, given Iowa's superior speed, that doesn't amount to much. A Fletcher can outturn either battleship under discussion, but I doubt you'd put your money on it. If Yamato wants to stay in a small spot of sea under the fire of radar-directed guns, have at it.
