HARM PB MODE NOT EFFECTIVE AT DISTANCE...

AFter a failed mission using HARMS PB mode at 45nm > SAM11 I put a simple SAM11 3 object on a map and approached at 30k.  HARM PB mode aircraft pull up consistently inaccurate i.e. useless if fired beyond around 22nm.  HUD will indicate in range at 50 60nm but no chance.... at 20nm it will hit OK but of course the SAM11 has one back at you...  TOO mode is accurate and safer getting a hand off around 25nm.

Is this being currently being looked at ??? (before the hassle of making tracks / video for ED)

every SA11 launcher has own track radar and their actions depend on search radar(snow drift), SD searches and if it finds any target to fire, tells launcher. and SA11 launcher turns to target, starts emitting, finds target and fire, if you want to hit launcher(and one of the track radars for this case) you have to come closer(around 20 mile, as you said) to make sa11 look at you and fire at you. so that you harm can find the launcher's radar signal. if you hit snow drift first, the effectiveness of launchers will reduce significantly but they can still find you and track you if you are close enough.

Thanks Solo... It used to be child's play launching Harms at great distance for SAM11 in PB.... now your descriptor seems R/L logic is now in play.... which is all good.  I'll dust off the TALDS and get a few mates and see how she goes with this knowledge before bothering ED... (tnx BN)

Trackfile attached.  SAM11 unit, 1x C2 - 1x Snow Drift SR & 3x Firedome launchers.

Approaching at 20k, once RWR shows SR active, HARM launched PB around 30 miles out, clearly steering towards Launcher but missed by several hundred yards. 

Came around fired a second from about 22nm which steered for and hit a separate launcher.  Came around and fired TOO mode from 20nm which steered for and destroyed the SR.  The 2 remaining launchers continued to actively target well beyond 20nm.

No idea if this is correct programmed behavior or not but on further testing it seems sometime all components need to be destroyed and at other times just one launcher makes makes the SAM11 group nulled.  PB mode certainly does not bring much to the party for the SAM11 which if intended is a bit of a surprise but not a big deal....

You have entered the code for the launcher, but it is not active, so the AGM-88 does not see anything.

The code for "SD" Snow drift SR is 107, not 115.
