Thanks Rob, I did download it and will check it out. This is curious. My autocrew picked up a fast moving Alpha via the Towed array at 20K yards. Finally i thought they are doing their job. Sea stae was one with very little surface traffic. I made sure i was on the same side of the thermal as the Alpha. I let the Alpha het to 6000 yards of me and was in position so my hull array could pick it up and the frigging crew classifies the Alph as a false contact

This is on a 688i platform to boot. I was able to do myself at a much farther distance, but the point here is why does the autocrew act like friggin dupes? I think the arrays might be OK. My suspicion is that the autocrew really are working for the enemy or some crap. I will see if there is a way to boost their efficiency. Thanks for the info!
