Ah, the loading machine! Brings back memories. Spent many an hour drilling gun crews on that torture device.
As a Gunners Mate I had to know each crew member’s duties first hand, so I had to go thru all the drills myself and then did it for real in a mount and turret. (Rick’s correct. They are different). The “projectile” was a solid piece of brass turned to the dimensions of a real projectile. The 5"/54 powder case and projectile were a little heavier than the 5"/38, weighing 32 and 70 pounds. During a drill there were actually 2 cases and 2 projectiles that rotated in use. One in the mechanism and one to replace each as they were removed from the hoist. A vicious circle for the two guys throwing them around.
John’s 15-18 rounds per minute was what the book said but that rate could only be sustained for a very short time. It would slow to 10 or less as the crew tired and then even less as the supply of ammunition slowed (don’t forget, the magazine and ready room crews had to throw those cases and projectiles around too). When the elevation angle got steep, as in firing directly overhead, one or two rounds per minute was doing pretty good.
Rick’s right again about bag vs case ammunition. 8" and larger is bag and 6" and under is case, although some of the rapid fire guns use case for 8 inch. As recently as WW II there were bag guns in both 5 and 6 inch.
And AKMS, there is no such thing as a “swab-jockey gunner’s mate”. You are either one or the other. And it’s Gunners Mate, with capital letters. :) :)
I haven’t seen “The Carrier” on PBS but I understand it was the USS Midway on which I served one summer. But that was back in the days when it had a straight deck and lots of guns.
