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

@Faster_Boiiiii Since the dev thread was closed, gonna answer here. Although tbh I’m not sure on the effectiveness of spatial flares on 9M. They do slow down insanely fast, as they are basically like chaff but burning, so if the 9Ms IRCCM activates, they would have the same or even less effectiveness as basic MTV flares.

But I have no damn clue how exactly the seeker suspension is triggered and if it would happen with spatial flares

The AIM-9M uses three deafferent criteria to detect flares:

and all 3 need to be true? Then it might not trigger the size detection

Well, AIM-9M is currently massively underperforming and should have performance close to de-chirped AIM-9L tested by Britain.

Yep, seen that report before.

Wait the 9M use a dual band seeker?
Never saw anything about it, do you have more info on that?

My personal opinion
The best rocket will be

aim-9x block-2
smokeless, has better acceleration, captures targets that are ahead of the curve, and can instantly change the trajectory.
The only downside is the 128x128 pixel matrix, due to which it can go to a false target.

Then ASRAAM, A-Darter.
everything is the same but worse.

Then iris-t, mica-ir, aam-5, pl-10
because they are smoky and have worse acceleration and maneuverability, but have better range than 9x

Then pyton-5
It doesn’t stand out, but it’s smokeless and the engine runs longer. but may well go to second place.

Then R-74m
there is little data, it is smoky, its production and presence in the military are unknown.

if we take range into account this is a completely different tier list for sure which i think will play a pretty big role in how good they are

It wouldn’t be easier then to take a medium-range missile with an active seeker.

well with these modern seekers i think they would be much harder to defeat than an arh seeker would and some of these missiles have ins and datalink so they would probs play a lot like an arh missile

sorry what?

Maneuverability refers to the ability of a vehicle, aircraft, or ship to change direction or position with ease and precision. It is a measure of how well a vehicle can perform different types of maneuvers, such as turning, accelerating, decelerating, and climbing or descending. It is an important factor in the design and performance of vehicles, and can affect their safety and effectiveness in different types of operations.

you list the IRIS-T as having worse acceleration and maneuverability

YES, and was a video where 9x unfolds 90 degrees almost in place

no idea what thats supposed to mean
but you’re wrong.
i make a whole ass post about the iris-t, explaining it in detail and this is the result…

what a lost cause.

why do i even bother

I’m not saying that the Iris-t has poor maneuverability and acceleration, I’m saying that it’s worse than the aim-9x. the end.

“Why do I even bother.”
I don’t know, maybe it’s because of fatigue.

Calm down guys,

@reinshil i’m sorry but i agree with @Faster_Boiiiii and the 9X indeed has worse maneuvrability than the IRIS-T.
The IRIS-T has a special booster that help it to turn as sharply as possible off the rail. The IRIS-T only have a short impulsion while using TVC when it get out of the rail to have the tigthest turning circle possible., and then the main booster kicks in to make the missile accelerate toward the target. A feature the 9X doesn’t have.
From video i ESTIMATED that the IRIS-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.

The cost of this multi-stage booster is that the range of the IRIS-T is pretty limited.
And you should read the IRIS-T thread, it’s a good one.

@reinshil .About your list (even if its your personal opinion, i’m going to try to comment based on facts).

Smokewise:
Difficult to compare but from best to worse:

Very low smoke → low smoke → smoky
AIM-9X/ASRAAM/Python 5 → MICA/IRIS-T /AAM-5-> R-74M
Don’t know about the other.

Acceleration (based on max range, because by accelaration i think you mean kinda max range and by itself it’s not that usefull)

MICA->ASRAAM->Python 5->R-74M ->AAM-5-> AIM-9X->PL-10 → IRIS-T → A-Darter

By captures target ahead of the curve i think you mean gimbal ?

If so:

100° → 90° → 60/75° → 60°
Python 5 → ASRAAM=IRIS-T=A-DARTER=AAM-5=AIM-9X=PL-10-> R-74M → MICA IR

If you take about LOAL, then the IRIS-T/ASRAAM/MICA/Python 5/PL-10/AAM-5/A-DARTER are also capable of it.

By change the trajectory i think you mean maneuvrabilty off the rail?

If so:

IRIS-T-> AIM-9X/PL-10/AAM-5/A-DARTER → MICA/ R-74M → Python 5 → ASRAAM

TVC is the big upgrade here, since the missile can turn rigth off the rail.

Seeker wise:
From best to worse IRCCM wise:

ASRAAM Blck 6/MICA NG
Python 5 has the most pixel (320240) and is dual band
Mica has an unknwon number of pixel (High resolution but nothing else said) and dual band.
IRIS-T 128
128 but with special capabilities against DIRCM
ASRAAM=AIM-9X, same seeker, not the same algorithm behind tho, so one could be better than the other.
PL-10 : Said to be 128*128 (only rumors, no official statement)
R-74M: No IIR seeker, only a multi element dual band seeker.

A-DARTER : Somewhere between ASRAAM BLCK 6 and IRIS-T: Unknwon number of pixel and dual band. (and pretty modern)
AAM-5 : Somewhere between ASRAAM BLCK 6 and IRIS-T: Unknwon number of pixel and dual band (AAM-5B). (and pretty modern)

its just the nature of the seeker head. while other IIR seekers are full frame and basically like a camera, the IRIS-T is 128x2 and scanned mechanically with a mirror like 80 times a second(to my knowledge. the actual scan rate might be different) so in case of a laser dazzler it doesnt affect the whole image at once

Here’s a cool video of AIM-9X turning tightly after launch (not claiming it’s better than any other missile, jut think it’s a cool video):

@Aurelian_ROW about this image that you posted:

Spoiler

Some issue i have about it:
First off all WTF is MIKA, the missile never was called MIKA , always MICA even at the start (since it4s an acronym).

Didn’t know the Python 5 used scanning imaging.
On the other hand i know that the MICA and IRIS-T indeed uses scanning imaging instead of having a FPA (or a full frame IIR).
While this is usefull agaisnt DIRCM, the image is rigth, missiles used this tech because full frame imaging infrared didn’t exist yet (also called Matrix).
The advantage of a FPA seeker are:

  • responsivity and response speed (lower latency)
  • Simplicity/reliability (no moving part)
  • higher frame rates (whole image instead of scanning 2*128 pixel 64 times for 1 image) (if the 80hz figure of the IRIS-T is true then it’s not mutch of a problem)
  • lower computational requirement (no need to asemble the image if the image is moving)
  • better countermeasures resistance ( scan the entire scene at once , the flare is imediatly detected)

That’s the one i’ve got on top of my mind, there’s probably others
