Looks like I've got more training to do then!

Thanks P7 for your answer. What about the sensor difference between the two boats?
I'll rephrase the question - what do you do when you get a TIW, out of the blue and it's a complete surprise?
Shoot a spread? When should you enable them? Shoot ASW missiles? or just focus on evading?
Cheers for your help,
Stew
