Allow me to clarify just how far ahead American and British fire control was:

Yamato's fire control still relied on optical methods. Its radar was capable of calculating range but not bearing, which is a very important part of fire control: knowing where the enemy ship is counts for little since by the time your shells get there, it's moved away.

American and British radar was entirely capable of determining distance and bearing. What this means is that they can do away with optical methods.

What that means is that American and British ships can fire completely blind: in the dark, in poor weather, even over the horizon. Japanese ships can't.
