If Tanguska has ability to switch its systems to auto mode, just as ship’s defense, it should be capable of engaging anything incoming towards may it be shells, friendly aircraft or AGMs. Human response time to ID, classify, calculate and attack is too slow to do such task for that reason AI does a much better job in ‘auto mode’, also its much more dangerous as someone noted here with example of GW2 and Tornado. This becomes argument of not if system sensors can detect, but if Tanguska has ‘auto’ mode.
I place ПЗРК taking down AGMS in category of bugs.
