A question concerning the AA-10 Semi Active Radar Homing missile

[4H_Ccrashh]

I know that the semi-active radar homing AIM-7 requires a lock from the launch platform during the entire TOF of the missile from launch to impact. Does the AA-10 semi-active missile have the same restriction?

I ask this because I was practicing against an SU-27. I launched, he launched, I press, he breaks hard to his left , beams my radar and I lose lock. He loses lock as well, the launch warning and lock tones go away in my headset. Both missiles go stupid.

As he turns back into me I get a lock with a sidewinder and launch, then I blow up from a missile hit. His AA-10 that had gone dumb got smart again as his nose came on.

I was under the impression that once semi active radar homing missiles go dumb after launch they stay dumb. At least my AIM-7 does.

In Tac-View you see his missile go straight and dumb as he maneuvers, then gets smart again. It was going to pass down my left side  but instead makes a hard left turn and hits me.

I'm running the latest beta with the super carrier mod.

Attached is my track and the TAC-VIEW File

Reacquisition at this point is an unlikely proposition, it'd only be possible with FLOOD mode and even then, very unlikely it'd happen IRL. AI probably cheats here to make it much more probable.

Make sure your jammer isn't active when you're being launched upon. The R-27 family has HOJ capability, and you won't get a launch warning even though the missile is still tracking you in that case.

Thanks for the reply's.

No the jammer was not active. I'm going to do some more practicing and see if it happens again.

Well that didn't take long. It happened again. Attached the Tav-View File.  Same thing, we both fire he evades all missiles go stupid. He turns back toward me and his missile goes smart again. This time I got another lock tone in my headset. I assumed he had shot another missile. I went into the notch and barely made it. Died later but that is a another issue completely related to my inability to fly the jet correctly.

Maybe this thread should be moved to an official bug thread. The AA-10 Semi active being able to reacquire is a major advantage over the AIM-7 and as far as I have researched not at all accurate.

just for giggles last post in this thread, I don't want to beat a dead horse. Happened again. This time I took two AIM-54's. Shot down one SU-27 at range  switched to Sparrow, locked second guy up at 20 miles and launched head on. He also Launched. He evades my missile but also loses lock.  I switch to heaters and close in.  His nose comes around and again his missile which had gone dumb and was suppose to pass down my left side gets smart again, makes a hard left turn and reacquires me.

TRACK and Tac-View attached

In DCS, all SARH can reacquire if you relock the original target, and the target is still in the missile seeker's FoV (under special conditions you can actually make it relock to another target but thats a whole other can of worms ).

If you are in the tomcat there is currently a bug where the RWR spike will stop showing if the bandit maneuvers. I’ll bet you are seeing this. I’m not 100% on what exactly causes it but it has something to do with the threat maneuvering, and then your spike will fade, then after they pitch back even if they are still spiking you (locked supporting a missile) they show back up on the RWR as nails, so you think you are safe, and their missile is still guiding.

 

It sounds like you are running into this issue. It’s been a bit of a problem over the last couple of months since you will just run into his missile with zero SA that its still guiding.

 

Recommend you post this in the Tomcat bug forum to see if they have any additional data on it.

Bringing this back up. I was on a 4Ya server in a tomcat.  Engaged an F-14A he launch a sparrow, I launched a Sparrow. He maneuvered and lost his lock on me . His sparrow went stupid. He turned back in got a radar lock and his Sparrow got smart again made a hard left turn and hit me in the face.

Sparrows should not do that.
