RA Mk48ADCAP fails to find the target.

[Ghost Dog]

I've noticed that too, especially vs targets with anechoic coating, ie modern subs. My solution: fire 2 torps at each target, the lead torpedo being active, the trailer being passive. Chances are he'll cavitate and at least your passive fish will get him. Active underwater seekers in RA seem to have shorter range and are easier spoofed with countermeasures but they do tend to make the AI run.

The new seeker behaviour in RA is likely for multiplayer balance. It's my understanding the new ADCAP Mod 7 CBASS can switch between active and passive modes as needed during the terminal homing phase. Perhaps more proof or documentation is needed before Ivan will add it to RA.
