#2> The second step in classification requires analysis. It takes 30 to 45 seconds to get a look at a new detection and discover what kind of engine she’s running, what kind of hydraulic pumps are online, and what screw blade configuration she is using.
One can imagine ML making this job somewhat obsolete in the not-too-distant future.

#4I'm not normally one to promote Hollywood but the film Greyhound (2020) with Tom Hanks does an _excellent_ portrayal of this technology (albeit slightly more primitive) in fighting German U-Boats in WW2. Well worth a watch if this interests you.

I was just going to say exactly this.
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.

#8I've heard the sonar ping from a submarine is so powerful that it will kill you if your a diver near the sonar dome.

#9This[0] is an interesting account of an accident with a submarine and how sonar played a role in the event.

That movie and Master and Commander are two movies that helped a digital nerd like me understand how an incredibly complex system can be managed by lots and lots of humans playing very specific roles.
