Hey it's a bubblehead!
I volunteered for subs but got picked for carrier, so glad I did honestly but I got to train on an S5W sub and later repaired the S8G prototype in Ballston Spa and I was shocked at how huge the engine room was compared to the old boomers.
Kinda cool that I was in the navy from 1996-2005 and got to work on a WWII destroyer engine room, 2 1960s reactor plants, a 1990s reactor plant, a 1980s sub engine room, and a 1990s sub reactor.
