I was on WWII subs in 1951. My bunk was situated so that the lower half of my body was alongside the bowplane motor. A couple of times the guys on the bowplanes in the control room would run them down to the stops. A loud THWOCK! and a bright flash would follow. More than got my attention.
Dad was EM1 on a Balao class during WWII... SS-318, the USS Baya... His rack was in the forward torpedo room, and he always joked that his bunkmate was a torpedo. Then when I got to go onboard one with him he showed me... He wasn’t kidding - you could lay on the rack and literally reach over a few inches and pat the torpedo on its side. I always thought it was no big deal to sleep with my combat gear on in the Army when the situation warranted it... But sleeping next to that much explosive and torpex just sort of made me shudder. I’ve never meet a WWII Navy vet that, upon learning of my dad’s having served on a sub, didn’t say something along the lines of “That was a rough way to make a living in the Navy.” But every submariner I’ve met always said “at least they fed us submariners well” in order to make up for it.
