AI P51's don't appear to be able to detect some ships

[Rolds]

P51's as wingmen or as their own group do not appear to be able to detect/attach schnellboots or U-boats. This came up when I had a group of them as wingmen and tried to get them to attack a U-boat with me. They never reported seeing the ships and would not accept attack ships commands. See track where an AI group of P51's fly over schnellboots and do not attack, even if as game master you command them to attack.
