At the WW1 Battle of the Falkland Islands the Northern Hemisphere
Coriolis correction in the British firing tables didn't hurt their
shooting.


This is the British Dreyer Fire Control Table, literally a 4-leg
table:

The problem is to reconstruct the enemy's course relative to your own
and then calculate the gun angles to place shells on where he will be
after the shell's time of flight, assuming both ships hold straight
courses, which they must when firing at each other this way. A fast
ship too small to shoot back might confound the system by maneuvering.

By WW2 US radar fire control was automated enough to shoot back
accurately while dodging enemy shells.
https://en.wikipedia.org/wiki/USS_Johnston_(DD-557)
Large armor piercing naval shells tend to act like solid cannonballs
and just punch a hole their size when they strike thin-skinned targets
that don't slow the shells enough to detonate them.

Some of those torpedoes may have been the spread that chased the
monstrous battleship Yamato away from the action. The Japanese mistook
those incredibly bold little destroyers for larger cruisers.
