You are obviously a great modder![]()
That's been obvious for some time now.

I just tested the new interception code and it is working beautifully. An interesting side effect is that you see more of a hidden mechanic. As air units get damaged, it lowers their interception chance. Since Air units are being intercepted a lot more, the defensive air interceptors are taking a real beating, so after 9 or 10 bombing runs, 7 of them (with 30% intercept chance each) are only intercepting 50% of planes now. So it balances air assaults quite well, IMHO.
As usual, this component is optional and can be disabled.![]()
Sweet. Amazing how small bits of feedback like this can so quickly turn into whole new mod components.

SR-71 still has to dodge them ALL!!!
I think it already has a very high evasion chance, but yes this will need to be taken into account in your mod Aff. Realistically even with massive air defences it would still be nigh impossible to bring down a Blackbird, at least in present times (future era is a different matter).
