I have read the comms channels underwater are low to very low bit rate. If true, a remote controlled sub seems unrealistic.
Also a remote control sub would be continually sending data back which surely is tantamount to continually yelling "I'm here! I'm here!", so I don't really buy the RC sub theory yet. (edit: I don't buy your suggestion that it's possible to hide that. You just need to emit too much power and you can't hide that).

- bsagdiyev 7y agoCorrect, you can’t remote control a submerged submarine, you get maybe a few characters per minute rate of transmission. There are a few ELF stations throughout the world, the US, Russia and India all having some. Some more info: https://en.wikipedia.org/wiki/Extremely_low_frequency https://en.wikipedia.org/wiki/Extremely_low_frequency which has my favorite quote. “ ... few nations have built naval ELF transmitters to communicate with their submarines while submerged. China has recently constructed the world's largest ELF facility roughly the size of New York City in order to communicate with its submarine forces without having them to surface. ...” The antenna needed for these transmissions requires a lot of land.
