I was a
successful Weapons Officer, which means to say I never did carry a MK-16 Torpedo! I did go to School on them, along with all other SSN-637 Class usable weapons.
I do not know the answer to your question.
A fun story, I think, involves the Torpedo Record Book for some of the MK-14s. (Every Torpedo had a Record Book, that recorded major maintenance, transfers to different boats and ships and stations, Mods, etc.)
Occasionally we would receive a MK-14 Torpedo that had been built and loaded on a boat prior to August 1945. One or two, IIRC, had been built at the old Torpedo Factory in Virginia. We always got a chuckle out of the notion that the weapon in front of us had been loaded onto a boat as a warshot under wartime conditions and disappointingly had come home to be off-loaded. (Kind of like a long career as a Kamikaze Pilot.)
We always treated those old girls as something special and showed a little extra respect for where it had been.
