Sub-calibre guns question
Posted by Bob Wiringa on 10/7/2020, 3:17 pm
I've seen occasional photos of battleship main turrets with small guns (for example, a 90mm on a Dunkerque's 330mm mount) mounted beside, outside on the turret turntable. I gather these had something to do with gunnery practice, being used instead of the main guns to avoid barrel wear. But how were they actually employed? How many navies used them?
