I don't know if She She Pings but the Collins class subs and the US Virginia Class subs sure ping enough to be heard underwater with today's technology and we know this after the Titan implosion was detected by the US Navy and they told us they notified the US Coast Guard of the detection in that location . I wonder who among us on this thread would be willing to serve on a submarine of any sort in wartime these days knowing what we know now about America's [and who else?] ability to detect the implosion above the Titanic wreck site way out in the Atlantic ocean. Anybody here keen to put their hands up to be an aussie submariner ahead of being a sailor on an Aircraft carrier? Underwater drones exist and are in the arsenal of our potential enemies.
