(WIP) Modern IR (FOX2) Missile - History, Performance & Discussion

Yeah those modern TVC missiles are really impressive.
That’s why when i see people thinking we need the 9X in game to counter the R-73 i’m always trying to tell them it’s too op.

Ircc the thing is that FPA seeker still have some DIRCM capabilities since the laser is going to blind only 1 pixel of the frame (the one that see the laser) or maybe a bunch of them but then the missile just goes “home on jam” and tries to impact the laser. It sacrifies it seeker but still know the general direction of the laser so it can just guide toward it.
It wouldn’t work only if the laser blinded the whole frame, but the same can be said of the IRIS-T, if the scan rate is 80 times a second then if all the pixels are blinded , when the scanner look at them it sees nothing.

RIS-T should be able to do a 180° turn in about 2s while the AIM_9X should able to do it in about 2.5s. So it’s close but the IRIS-T is still at an advantage.

more than 90 degrees per second

Acceleration ( kinda max range)

nope I mean instant acceleration. although this is debatable with 9x due to the lack of smoke.

i think you mean gimbal

close but in my opinion it’s called differently

100° → 90° → 60/75° → 60°

AIM-9X → 90°

And in general iris-t and aim-9x are similar in terms of performance characteristics.
Well, according to you, Python 5 should be better

(0:58) AIM-9M as always, a flying slowpoke, with an unstable flight trajectory.

And by the way, you don’t have data on the motor in the video irl, it has much lower acceleration and longer operating time.

There are even rumours that the IRIS-T can do up to 120g because of a comment made by Diehl BGT Defence

AAM-3 is already so hard to get info on, AAM-5 might as well be made up by Gaijin…

These are like the only things i have on AAM-5 and they still don’t really mention numbers

@Patriotic_FR I hope gajin consider another infrared Air-to-Air Missile PL-5E, PL-5E II, PL-8B, AIM-9M-8, AIM-9M-9, AIM-9L/i and TC-1 in first major update & second major update 2024

full frame seekers cannot possibly provide the same accuracy. thats just how it is with lenses and a sensor. you get the same effect when shining a laser at your phone(dont try that).

the special thing about IRIS-T is that it physically doesnt “look” at everything.

This article is a summary of a research paper written by the same author on the resistance of IIR missiles to DIRCM. The conclusion is that full frame seekers appear to be highly resistant to DIRCM.

A DIRCM system doesn’t block out the whole seeker image on an IIR missile:

Even when very high power lasers are pointed directly into the seeker the seeker still produces a clear enough image to allow for home on jam:

There are other research papers online that also back up the claim of conventional DIRCM being ineffective against IIR seekers.

Here is the full paper by the person who wrote the article. This is the concussion:

The first section of this paper illustrated the capability of an imaging seeker to track as long as any target feature is detected, even in the presence of a large area masked by a jamming laser. The second section showed that the laser jamming signal does not saturate all of the focal plane and therefore the jammer (and target) location is still detectable, even when there is sufficient jamming energy to cause damage to the focal plane. It seems that the future countermeasures for imaging seekers are more like a DEW (Directed Energy Weapon) than a jammer, and such technology will soon be within reach13. Until DEW are used, the data shown above leads to the conclusion that simple laser jamming or dazzle will not be effective against imaging seekers.

thats pretty cool ig

i wonder if this is affected by the lenses

I have a question about FOV gating. For missiles that we have in-game with FOV gating (R-27(E)T, Magic 2, R-73), what happens when a missile is initially locked onto a target and still on the rail (before launch)? Does the seeker head remain with a wide FOV until it is launched, or does the seeker shrink down the FOV the moment it acquires a target, even if it is still on the rail?

Judging by the lock circle HUD in-game, the seeker remains wide while on the rail. How does this work IRL?

so for crossed array detectors like the R-73 the way they work is its an FM style seeker divided into 4 detectors in the shape of a cross (hence crossed array detector) each of these detectors are very thin which the game acknowledges by making these missiles have an IFOV thats also very tight. The way the crossed array detector IRL works is it tries to keep the frequency a signal appears in each detector as it spins around in a circular motion constant. So the way these detectors ignore flares is if a flare enters one detector it sends a signal but since the flare is not the target the frequency between the last signal in the previous detector and the next changes, this offsets the image and the seeker counteracts this by comparing to the control signal (previous cycles where the target was centered) and adjusts accordingly quickly filtering out the flare. Also since the detectors are so small flares leave them very quickly so adjusting is a simple task. IRL the best way to counter these detectors was to dump flares because by flooding all the detectors with this new signal they cannot properly adjust and as such cannot tell apart the signals recieved from the original target and the flares

image
In this image basically imagine the image crossing each detector at relatively the same point, when it does this the time it does so is at a constant frequency, when it becomes off set because something else crossed the detector at a different point the image offsets which increases or decreases the frequency of signals recieved which will cause an adjustment to fix that to return to the constant frequency.

TLDR is basically how war thunder does it where detectors are so small individual flares quickly leave the detector (IFOV)

IRL the “FOV” or Boresight in this case is the scanning pattern, it will go around in a pattern until it finds a target and once all 4 detectors are aligned tone is given and fire away.

Am I correct in thinking that the R-73 seeker first scans in a wide pattern (nutates?) and once it finds a heat source it snaps onto it and remains on axis (like in the image)? Would that not mean that once the seeker has snapped onto the target the game should reflect it by narrowing the seeker FOV we see in the game (I am talking about the small circle inside the big circle getting smaller)?

That is how it should work. Same goes for all of these missiles which have FoV reduction. Without this, pre-flaring is more effective.

Aster 15/30 does have thrust vectoring on the booster and lateral thrusters on the “terminal dart”

sources are few tho, and i don’t know how reliable they really are.

one of them mention it here
https://www.sciencedirect.com/science/article/abs/pii/S1270963816307003

as for mica it can turns pretty well (not going to get into the debate of which turns best, but it should do the job) :

and VL version (one launch at the end with a pretty tight turn)

someone please suggest the Aim-9L I-1 for the german tornados man…

do you want them to go to 12.3?

i doubt that giving two aim-9Ms to the tornados will grant them that br,
but if it will,
i guess we can restrict it for the Tornado ECR, the F4F-ICE and the EF Typhoon


its not even that bad
giving it 2 9Ms will at least move it up to 12.0
Tornado ECR will never come. its an entirely redundant addition for war thunder
