Mk 48 ADCAP/CBASS still has comms imprediments despite its capability - the kicker with torps such as CBASS will be when untethered comms management improves.In retrospect and AFAIK that's basically one of the capabilities of a Mk 48 ie. locate a hostile with active sonar and communicate this back via tether to it's mother ship. Though this new UUV doesn't appear to a kamikaze.
it will be a generational and quantum leap in smart torpedoes....
the other thing is the rapid developments in AI.
eg look at the mobbing AI demonstrated recently with unmanned harbour patrol - its not a huge leap to migrate that smartness to mobbing USV's as hunter killers in a SLOC
energy mgt is the key to all of this. just a damn shame that there is no gentle way to build a sodium generator so that the platforms run on "infinite energy" principles
