Anyway, you can tell the mx where to look for its intended target and you can tell it what the target is doing at launch. You can't tell the mx what the target does after launch, you can't tell the mx what else might be in the (expanding) uncertainty box and you can't easily determine what the mx has targeted when and if it finds something to go after.
May I respectfully point out that the AIM-120 from day one way back in the '80s had a datalink that enabled the launch aircraft to guide the missile's flight and tell it when to turn on its internal sensor for terminal homing? In other words, if there was uncertainly about where the missile had gone and what it was going to see when it got there, the missile's internal sensor would simply not get turned on. The missile has improved mightily since.
Would I like my wingman shooting a LOAL mx into my furball? Erm, not really, thank you.
May I respectfully point out that the point of an LOAL shot is to AVOID the furball, and not to engage one.
