We had a volunteer here that was on Iowa in the 50's.....some real interesting stuff on getting that stuff to hit what you want.
He did weather....never really thought about it, the different temps, pressures, winds at different altitudes all effect just where that shell is going to land over the many miles to its target.
He told a story on gunnery practice that was off of cuba....they had a ship pulling a barge that pulled another barge that was (i want to say 30 miles behind the ship with people on it) that was the target.....the barges are like 5 miles apart and then the ship with people on it is like 20 miles in front of that....I think I explained this right. Anyhoo on the first salvo they hit the first barge behind the ship and that was it for practice.....he said the captain was not happy....the sound and the shock from the guns just amazing.
He also said being the weather guy he worked in the only area of the ship that had A/C and it was there for the fire computers....early tubes. He also won a lottery to use FDR's bath tub.
He had some cool stories about shore leave in pre castro cuba.
