  1.  @ycplum7062  If you are defending a coastline against incursions by nuclear boats, the diesel (or other non nuclear) boats have the upper hand and become the hunters. I would agree that it wouldn't happen in the mid Pacific.

  2. It's pretty hard to make a non magnetic electric motor and they all have them, nuclear boats included.

  3.  @ycplum7062  Even a hovering helicopter?

  4.  @ycplum7062  Most of the nuclear boats out there can't operate in shallow coastal waters and none of the boomer subs.

  5.  @ycplum7062  So, in yet one other way, diesel/electric boats are stealthier. I would never have considered that they might have lower magnetic signatures as well as being quieter. Conventional subs are far more dangerous than their "press" would indicate that they are.

  6.  @markbrown4442  Hmmm China's first sea battle in their entire history in metal vessels .... seamanship and experience count for a lot. The PLAN is still amateur hour.

  7. @Drew Peacock How do you demagnetize things like electric motors?

  8. " is there not technology being examined to detect subs by their wakes?" I am aware of a technology whereby they "sniff" the water looking for the ionization products caused by particles emitted from nuclear reactors, thus locating wakes.

  9.  @Mar-s5q8m  .... angles not normal to the direction of flow ... Wouldn't that create cavitation?

  10.  @Mar-s5q8m  Yes, I see ... as long as there is no significant pressure difference between one side and the other ..,

  11. "the ping of an active radar bounces off the air inside the submarine." You need to have a second pressure hull outside of the first one with a vacuum maintained between the two., then.

  12.  @Kyoptic  Yes but the sound waves wouldn't propagate through the vacuum layer in either direction. Anyway, you are right it would be impossible to do. You have to wonder though if the place for a second stealthy sound disrupting layer is between the outer hull and the pressure vessel inside.

  13. @Drew Peacock Hmmm. Remove the crew first, if you please.
