USS Iowa fires a full broadside of nine 16 inch (406 mm)/50-caliber and six 5-inch (127 mm)/38-caliber guns during a target exercise.

Okay, this brings up a question I've long had about large guns, but never looked up. How are large guns classified in caliber? A 16" gun is a 50 caliber? A 5" gun is a 38 caliber?

Chas.

Also Charles they are in Field Artillery sized as this, 5 inch is 155mm and 16 inch is 406mm like almost everything military it is called in the metric system, 8 inch is 203mm

Also cannon and howitzers are different, cannon are full aspect ratio and howitzers are 2/3 ratio. I spent 14 years in FA not as an officer, enlisted NCO
