Somehow it never occurred to me that underwater drones were a possibility even as I’ve literally watched underwater robots do things.

Probably a hell of a lot easier to build and don’t have nearly the same weight challenges as it doesn’t have to, you know, fly.

I was referring more to small stealthy surface drones, like Ukraine's can carry a 200kg warhead and have a one-way range of 800km, but underwater drones... I mean, that's pretty much the literal definition of a torpedo, no? A modern Mark 48 torpedo has an estimated max range of 38 km at 55 kt or 50 km at 40 kt, probably even farther if you ran it slower... or if you weren't trying to fit it into a 21-inch-wide tube.
