If you ever wondered how, or just curious about all the systems a WWII sub used and how they worked this is the video to watch.
15 minutes, it loops once.
Its titled incorrectly, it is a WWII Sub ops movie from that era and I recommend anyone that enjoys the immersive nature of controlling the subs system watch it. It also give you a sense of what is urgent during a damage control scenario.
I found it wonderfully educational.
