    Why did it never occur to me that drones should go underwater? This is brilliant!

      It’s more difficult as you need to be able to communicate with it and water blocks a lot of radio frequencies pretty well.

        you need to be able to communicate

        Not necessarily. Piloting the weapon into position with internal navigation, then having the thing recognize and engage targets autonomously is becoming common with drones.

        Also, you can just trail a very long wire behind the thing to communicate with home base. This is how torpedoes have worked going back to the Cold War.

          True and there have been numerous advances in and deployment of drones with anti jamming basically dragging 5-20miles worth of fiber cable behind them. makes the landscape look like a giant spiderweb though so that’s neat.

            Torpedos, sure but I’m impressed that the wire in fly by wire missiles can withstand the fire coming out the back. Even if placed away, they’d still be in the jet stream.

              The wire is glass fibre optic so I guess whatever temperatures glass can withstand for the brief moment that segment of the wire is near the heat - remember it’s continually extending cable

        Just like air drones in Ukraine carrying kilometres of fibre optic cable, sea drones may do the same

        I thought you were talking about Minecraft for a second there when I read “water blocks”
