#1 Diesel subs in shallow water have always been a huge danger. The Soviets kept them in shallow waters near their harbors and the Chinese keep them in the shallow waters between them and Taiwan.

All the turbulence in shallow waters make them hard to hear and if they are stationary or running slow, those batteries make zero noise and can stay down for a very long time. MAD detection (magnetic anomaly detector) is about the only way to find them in that state and that requires planes to fly in hostile skies.

Flying drones or swimming drones might work equipped with MAD, but no R&D has been put to that as far as I know.

#3 I suspect active sonar could help a lot. All a UUV drone would need would be a really loud pinger and enough AI (which wouldn't need to be much) to avoid broadcasting at the location of its launch vehicle. It wouldn't need any processing, the launch vehicle could do that.

#4 So where did our sub just run into an uncharted seamount? Could it have been one of these?
