    Maybe a small floating buoy with a communication package/antenna on the surface thats tethered to an underwater drone?

      My guess: Waterproof outdoor fiber cable, several km’s long connected to a relay out at sea. The sub unspools the cable as it moves in.

      This way it avoids all jamming or detection from observers.
