It feels a bit strange when you hear naval people from the 40s talking about 'computing a firing solution'. But these systems must have been reasonably sophisticated for 2 moving warships 10+ miles apart to stand any chance of hitting each other, allowing for wind, changes in atmospheric pressure, the earth's curvature, pitching and yawing and coriolis force.
