Why does this keep happening with aim7's?

I shoot an Aim7F with a perfectly good frontal aspect PD lock with nothing to distract it in its seeker cone. Still, the missile decides to turn 180º and go land on the enemy airfield or something.

You fired a missile on a target with very little airspeed at a very high aspect.

It more than likely didn’t catch your signal and flew off to where it thought the enemy would be.

Totally frontal aspect here, and the sparrow is usually perfectly capable of hitting on the rear aspect unless the target matches your speed or notches.

Doesn’t matter how perfectly capable of anything it is when it isn’t launched with high signal fidelity.

It saw a nearby McDonalds and decided to go for a Bigmac before going after the target…

Honestly. no idea, never seen or had a missle do that before.

That happens to be the issue I’m talking about. That launch should have good “signal fidelity” or whatever you want to call it.

Just watch the video carefully before defending broken things

Nothing went wrong.
First missile was launched during a notch so it had no radar return.
Second missile had a radar return.

Yes, and the missile hit.
Nothing broken about a missile hitting a target heading toward you.

Notch does nothing about radar return, absolutely nothing in this case cause he is in SRC mode. Notch only deceives doppler mode to ignore the return through filtering as the approach rate is 0.

This post was flagged by the community and is temporarily hidden.

First off, F-16 doesn’t have an SRC mode that isn’t PD for the transmitter.
Second, AIM-7s don’t have their own radars so their seeker being a “SRC receiver” means nothing cause the PD radar from the aircraft isn’t giving the “SRC receiver” a signal.
Third, I see HighRisk’s recent post is attempting to derail this discussion with provocations against innocent parties rather than being on-topic.

In case you guys don’t understand what happened in the video:

1- First dud launch was frontal aspect, I specifically waited for the mig23 to get his nose on me before launching
2- lock is absolutely fine, I only unlocked when I saw the missile going haywire to relock for the 2nd one just in case it was a radar bug
3-missile goes haywire even though its radar seeker is tracking the target absolutely fine inside the painted zone by the aircraft’s radar, despise the “SRC” from launch.

4- I suspect this is another case of cheap and unreliable servers by Gaijin, but I only get these with sparrows and the like, never R-27R / R-27ER

having watched the replay a few times. I think this was the sequence events.

You fired the missile just as the target was switching from going right to left to left to right (0.09). The missile begins its launch tracking the targets predicted path and in the second or so it takes the seeker to home in on your lock, the target has totally shifted position and is no longer within the FoV of the missile (0.11). The missile continues the turn without input based upon where the target could theoretically be if it had still been going in the same direction at hte moment of launch.

But it is a really wierd sequence of events. If you say this keeps happening, then it would be good to start recording it a lot more, and possibly even submit a bug report for it. It to me, looks like a 1 in a million sequence of events and shouldnt be happening on a regular basis.

As to how to avoid it… Maybe wait a second or 2 before firing, confirm the target’s path to set up a solid intercept.

The missile went haywire with the target still within its seeker’s FOV, only went out of FOV after the missile was already turning away from it.

Yeah, but I wonder if the seeker had activated though. I dont know if Aim-7Fs have a slight delay (looks to be about 1.5 seconds which is fairly common for activation delay on missiles) and the replay is just a bit buggy or lying to you (wouldnt be the first time)

So you fire at 9 seconds
at 10 seconds the target shift angles
at 11 seconds the seeker arms but the target is no longer in FoV

or something. I really dont know, but that would be the sequence of events I would guess. But I think this is gunna need a tech mod to answer

Other than server issues, I can only think of a track rate limitation maybe

That is possible. Was it a high ping match?

The seeker was active because the missile had a correct path initially, when the mig23 went fully frontal aspect, the sparrow started turning away from it and eventually the target went out of the seekers max FOV even though the missile own seeker was trying to follow the target correctly.

That sparrow knew where the target was, and where it wasn’t. But sadly it didn’t know where its fins where

Not for me, but I’ve noticed ridiculous stuff against high ping players. Like their aircraft appearing in a different position in my client.

For example, in my client a guy was on my left like in formation side-by-side (overshoot), but on theirs they were trailing behind my six. Then they shoot into nowhere (from my perspective) but I get suddenly killed because in their client they still were on my six

Yeah, anything is possible. Wouldnt be surprised if its a combo of issues.

My recommendation going forward (unless a tech mod sees this and has a better idea of what the hell is going on)

  1. log any other similar missile behaviour, if its common, submit a bug report. Try and save the clog and a screenshot of the missile doing its thing. Also share the replay, perhaps even in this thread for comparison.

  2. delay firing a few seconds. Looking at that replay, I would say you fired 1-2 seconds too early (at least compared to how I would engage such a target) so perhaps sit on your shot where you can and just be patient, id have fired just as it came out of the turn, rather than as it was entering the head-on (I’ve also found that delaying the shot seems to fix a lot of problems, I think the game freaks out when you arm and fire a missile too quickly, and thats all missile types)

Sure will do. But waiting any longer on that situation would result in a trade at best if that guy had an R-24R left and was aware of me. I had a perfectly good lock and waited till he got fully frontal because I saw him looping and going very slow and I didn’t want to possibly waste a missile. Tough luck…

After that kill, I had an R-27R launched at me from the remaining enemy in a premium mig21, I notched it successfully at first but got out of the notch and the missile reacquired me again because of datalink. I exited the notch too soon but if I kept notching I would have to deal with an r-73 at short range while being defensive anyway. Well, you can’t win them all. Luckily that teammate was able to run him down and we won.
