Summary0003600: R27-R missile possible problem
DescriptionMaybe it is intended but I am unable to hit anything with it.
The radar is locked on, however when target deploys chaff and flare the lock is lost, although the target is still in my sights and locked.
Do flares and chaff even suppose to disrupt the lock, thermal - yes, laser - may be, but radar ?

Chaff is strips of metal designed specifically to spoof radar

Okay then it is intended ?
However it is still difficult to hit with that radar lock.

The vanilla R77 missiles are still jammed by the AI little bit, but they have a decent hit probability. But with R27 they jam like 100% of the time.

BI r77 has cmimmunity = 0.85 where r27 use 0.8.

R77 uses inertial guidance with mid-course update and terminal active radar homing, where R27 use just semi-active radar homing so it's natural they behave differently in game.
