It’s amazing to see them doing this with such incredibly basic technology.
- Having to draw their ship and the submarine and constantly update its movement.
- sonar guy is just looking at a screen that blips every now and then.
- all communication by morse code - must be horrendously slow in the heat of battle
- even communication within the ship is passed between multiple people so big chance of Chinese whisper type errors.
I don’t know how realistic it is to real life but it gives you an appreciation for how smart and situationally aware the captain of the ship needs to be.
