Mau, thank you!
I was getting AEGIS ships to fire at link missiles contacts, sometimes up to 70nm away! I accomplished this by disabling the requirement of the AEGIS SM-2's to require the FCR to lock on the missile.
This was done to experiement with the parameters which limit engagement.
The solution put in place now, is to still require the FCR, however the range of the FCR's on AEGIS ships has been greatly increased. Previously it was limited to picking up missiles within 10nm and that was way way too short. So, now, the ships still require the FCR, however for "no-warning" threats, there seems to be a delay between acquiring the missile on the search radar, and the ships painting the vampires with their FCR, which slows down launch a little bit. With link or launch-track warning, the FCR radars seem to be on sooner and the ships have a bearing for the vampire, so engagement occurs a bit sooner.
Interestingly, a lot of this has been largely unintentional, on my part, and seems to be built into the sim. So I think this is another example of how DW was hardcoded with some amazing features, that nobody ever saw because of limitations in the database, in this case, the extremely unnatural range limits on the AEGIS FCR's.
