    ELI5: Passive sonar gives you the opponent's bearing only; Active sonar gives you the opponent's bearing and range; active sonar gives your bearing to your opponent(s); firing a torpedo gives away your bearing to your opponent(s). Why wouldn't you confirm a solution with active sonar before firing?

      Maybe you don't want to give yourself away!

      > Developing an intuition for these situations is hard. They never happen in real life, and we practice them in high-fidelity trainers where time is precious, so young officers don't get many reps. I thought it would be fun to cheaply simulate close range engagements on a laptop, and play against my friends on the web.

      I remember reading, decades ago, that the U.S. Navy's flight school in Pensacola had a student who'd done unusually well in the course because he'd bought a copy of an early version of Microsoft's Flight Simulator software (IIRC) with maps of the nearby Navy airfields used for student training. That led to the Navy adopting PC-based flight simulator software generally. (I couldn't find a reference.)

        That's exactly the type of thing I was going for here!

        >Some games, like the early-2000s Sonalysts simulations, accurately simulate TMA, but they are so complex that they are hard to learn. As a qualified submarine officer, I still couldn't figure out how to play Dangerous Waters.

          This is great! I loved playing Sub Command as a kid, and seeing the very familiar waterfall display was a real blast from the past.

            Seems like a good strategy is to circle slowly until you pick up a sonar trace and then try to follow it and get in the opponent's baffles. Converting the sonar trace into a map of the opponent's position over time is the essential skill and is something that I'm sure is automated in real submarines.

              One of my first Game Boy (Color?) games was a sub combat game. I think it was the first thing I ever ordered off amazon.

                I love submarines, military history, and all things that this should fit with, but I can't seem to get the hang of this. I kinda wish I could play it solo to just to figure it out.

                  I didn't make a solo game mode, but you can play against yourself by opening the link in a new tab if that's helpful

                  This is very cool. On the tutorial page, if you confirm the torpedo (and it fits) should you get a 'congratulations' popup?

                    yeah I love that!

                      Playing this for a few turns and you will see why they developed the banjo and then the Torpedo Data Computer. I am currently reading a fiction submarine warfare book (entertaining with warts) and they cover the switch over.

                      The book is Sink the Rising Sun.

                      The TDC is described well here - https://en.wikipedia.org/wiki/Torpedo_Data_Computer

                      Manual for the banjo here. Imagine a slide rule that could solve the problems in this game (given perfect input data) - https://maritime.org/doc/banjo/index.php
