The Navy Isn't Prepared To Face The Growing Diesel Submarine Threat
2021-11-03
[The Drive] Before I fully understood the implications of AIP, I believed there was nothing new to fear in the old. I was wrong. In fact, if you take into account propulsion, tactics, and implementation by adversary navies, there really isn’t anything old about the new. Once again, we have placed ourselves in a disadvantaged position. ASW created the dragon that is AIP— but there is no reason ASW can’t develop the means to slay it.
Long article, the best stuff starts about 2/3 of the way through.

#5  ...Xi did you lose another submarine?

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

#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.

#2  AERIAL MAGNETOMETRY WITH DRONES

Underwater Drones Could Be the End of Submarines

#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.
