@TOPOLO That is absolute nonsense. As long as the RADAR has good track and doesn’t lose the target, the RADAR mode should not matter (RWS/TWS soft-lock vs. STT).
STT just makes the RADAR focus on that one target, but does not change the ability for the RADAR to track a target and provide mid-course updates to airborne missiles (TWS and firing on multiple targets at once).
If missile PK is directly linked to RADAR lock state then that is totally bogus.
If the targets are aggressively maneuvering, then maybe TWS can be wrong and mis-guide the missile, lowering PK as a result of the RADAR tracking mode, but in many situations this isn’t the case (remembering the relative motion of the target is small from the perspective of the RADAR viewpoint). Only if the target makes large vertical maneuvers or starts beaming will PK materially drop, but that would happen even in STT.
@fvelazdem What difficulty level were the AI? If ACE, they are all-knowing, perfect pilots and will evade most missile shots. Try Veteren if you find they are too good (I know I do).
I went 1 vs. 2 BVR with 2x Su-27 and they would evade everything I threw at them (usually just by turning cold and dragging the missile). I’ve seen the same with other AI aircraft at ACE level.
