Instead of making the subs quieter is it possible to jam the opponents sonar capabilities?

That reminds me of something. I have always wondered whether a SURTASS-equipped ship could be "jammed" by simply trailing a loud ship or two (like a container ship) beside the spy ship's TAS line and randomly cavitating its props. This would be a far less provocative act than actually cutting the TAS line.

Those ships (and subs) contain pretty powerful processing hardware for the purpose of sifting through and isolating individual signatures though, right? My understanding has always been that with subsurface warfare the game is to leak as little and as weak a signature as possible. I imagine a loud jamming signal would be easily isolated and filtered out.

It would be similar to any signals jamming. If you hit the received with enough interference, you can overload it and stop it from being able to register any useful signals it might pick up.

But to do that means you need to hit the receiver with more energy than its design tolerances to either trigger self-protection features like auto-gating, or to potentially cause real physical damage to the sensor.

I'm not even sure pining with active sonar at close range would be able to do that, so you probably need to develop effectively a kind of sonic weapon.

To do that would be far more provocative than even deliberately cutting TAS lines in my view.

Do we have a way of knowing if it is refitted 094 or a brand new bulid? also, french, british, russia and us have either 4 or 12 ssbns, no? 5 would be a peculiar number....

Surely a new not modernised... the 4th # 412
