this is normal. you locked and launched rear aspect, where the exhaust of their engine is pointing towards the seeker, but they then turned to the left, so the engine exhaust is not as visible, so it lost lock.
By the time the exhaust is no longer in view, the missile can already get a lock through all aspect means, plus if u go to the bug report i put in, you can see the same thing happening against full afterburn jets.
Video is an AI bot Mig-15, they are bugged. You have this problem on them with all missiles. A4s are ok.
Both Videos in the bug report you shoot at a very hard angle. I never use 9Ms this way. I shoot them close range full rear aspect, so enemy has a hard time to flare them.
Test Flight Mig-15s are a bit of an issue, especially with just how cold they are. (They really need to change the AI aircraft for higher BRs)
There are a few things you can try to mitigate the issues though
Hold the lock for a second before firing.
Lead the missile better, rather than firing at the target, fire in front of it (some aircraft will give you a missile intercept point)
Fire within the LSZ. Aim-9s are not the most kinematically strong missiles, so firing within the LSZ helps a lot
But overall, it looks like the usual test flight buggyness rather than a specific Aim-9M issue. But i’ll keep an eye out in actual matches. We did have a 2 month period at the start of this year where they were broken everywhere
9Ms tend to be mediocre when in rear aspect if the guy you are shooting at is paying attention, so side aspect is usually the best choice if you have it, on both clips (which is kinda hard to tell cuz its sensor view) i do lead it, especially on the f14 one the missile when being fired is already going where the mig29 was going to be, it just gives up and goes forwards then blows up, if i had a 9L on either of those shots it would have hit, since neither flared
That isnt anything to do with the seeker though. Only how the IRCCM works.
Its much harder to defeat the IOG in side-aspect than it is in rear-aspect. But if no flares are dropped and the seeker shutoff never triggers, then the 9M is identical to the 9L. (though it should have a greatly increased lock range, which then helps with the tracking too. The Track rate can also be buffed)
Its outside test drive aswell, as shown in the bug report, i just put this one here because i thought it showed what i meant better, the LSZ thing you mentioned is true, ill try to fire only inside of it from now on see if it still happens, but AIM-9s after the B,E and J are pretty long range fox 2s, (compared to R-73s, R60s and so on), i think the L,G and M all have similar range so even when i change between them, they all feel the same, aside from the flare resistance ofc, its just the 9M that gives me issues lately
Only thing I will say is that replays dont always show flares, you’ll need to check the server side version, as I think you are on the client side version
Yeah i think it has to do with the seeker shutoff, but i can guarantee they did not flare, i still remember the matches, the Su-27 didn’t know i was there and the Mig-29 i assume just didn’t see it cuz it was GRB, that’s why on the bug report i put it has the IRCCM not turning back off since the missile just goes forwards, then either falls out of the sky or blows up, but just incase ill try to check the server replays.
Yeah that second video is exactly the same thing as the ones i sent! I just can’t find a way to replicate it, i also tried to find similar bug reports to mine, but theres none, it seems the 9M works fine for everyone else
even if it isn’t in range it would just go forwards to where the mig 15 was, not steer of into the left to the point where the entire planes leaves the missile FOV, i can guarantee that if i could see the replay of that test drive, the missile would have track on that Mig 15 the whole time, again just watch the other videos in the bug report
It’s possible that is what is going on in the clip linked in the original post. But Im not entirely convinced of that answer. Though it doesnt explain the clips in OPs bug report (Su-27SM at sub 3Km and Mig-29M within 2km. Though I think the second clip, the one vs the Mig-29M might just be a bad shot, rather than necessarily the missile breaking, but its really hard to know either way.)
Aim-9Ms have a well known track record of just going AWOL with no explanation and no consistant means of replication. Was fixed before, but they have been playing around with missiles in the past few weeks (prox fuse changes) and it would not be unlike them to end up somehow breaking it again.
The IOG might kick in and hte missile just keeps going to where the contact would be in an attempt to reacquire, but it does seem to overpull rather than maintaining its initial turn for that
