Sorted - working properly now - and running 'that' scenario again the UUV performed as trailed !!
Ran her in at speed slowing from time to time for sonar and picked up the Kilo at 3 nm when it spooked,
at the incoming, dropped a CM and ran. But (SQ haunts me) a torp would have had the same 'spooking' effect
and my sub sonar did a better job at picking up the the spookee.
The real question to be answered is at what range Mk2 will pickup a loitering Kilo while the UUV is beeing
deployed in a stealthy approach.
Impressed with the ASuW sonar performance in my first proper run though.
The Jurys out on ASW though, but good luck with that element .
