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

Gotta love that tail control with a lift body.

Same as AMRAAM design, without wings.

No offense, but the article linked about the IRIS-T states that it can pull more than 100 G, not 60 to 80 G.

No offense taken.
It’s just that i haven’t seen any primary source with the 100G figure but i’ve seen some saying it was 60G+.
I’ve seen other secondary source stating 60 or 80g and that’s why i putted it in that ballpark.
But the g limit is not the most impressive thing on the IRIS-T, it’s its turn radius which is obtained by multiple stage of boost which iirc don’t exist in other missile.

Thanks to it the missile manage to have only half of the turn radius of the R-73.
Indeed the turn radius is more influenced by the speed (squared) than by the g limit of the missile.

Anyways, if you find a primary source (not condidential), or multiple secondary source stating the 100g figure i’ll glady change the value in the post

No rocket in the world has yet managed to reach 100G

I think something thats actually kinda understated about the IRIS-T (and something that wont be modelled ingame) is actually its guidance law. Afaik, its one of if not the only missile using an H-inifinity guidance controller, whereas other contemporary missiles (or atleast missiles up to 4th gen IR missiles) use PID controllers.

H-infinity controllers are much more accurate and optimizable and much more suited to complex problems such as high speed interceptions (which is likely why the IRIS-T has such a high claimed intercept rate in Ukraine), but pay for that in cost/complexity.

I actually didn’t know this… what sources do we have on this so we can prepare in case gaijin does not somewhat implement this feature?

In lateral acceleration or axial acceleration?

From that reason with actual tvc realization, will be worst missile sraam level

lateral acceleration

How about this bad boy, It looks similar in design language to the european fox 2s like mica and irist

Spoiler

Pl-10 looks like the chinese copied an IRIS-T almost 1:1 but slapped on the MICA tailfins to make it look a bit different.

True, but i really don’t know how they’ll implement H-infinity controller instead of the classical PID one on the IRIS-T.
Since they already have so mutch problem in missile guidance with the TVC, having the TVC and the H-Infinity controler seems unprobable for now (unless they manage to recuit a specialist in missile guidance but even then it would be unprobable).

But if introduced, it will be fun to be able to intercept ennemy missile with your own IRIS-T (even if its intercept rate against A-A missile will be a lot lower than against cruise missile or shahed)

Like i said, they wont implement it. Its just a notable feature.

From what i read online , the PL-10 is rated as a 55/60g TVC missile so more maneuvrable than a 9X but less than an IRIS-T.
Range wise its pretty poor as its being rated as only 20/25km (so only a bit more than the AIM-9L/M that we have in game).

Can do that in game right now with the AIM-9B, have had people shoot down my fireflash/AA20 with their sidewinders in a head on multiple times.

Very annoying, to say the least.

You can already do that but its very unreliable to say the least.

The Iris-T should have a better time doing that kind of thing maybe 50% of intercept if the missile is detected.
(Number is completly made-up since idk why kind of effenciency it does have irl)

Missiles in WT are abnormally attracted to other missiles, its one of the reasons why radar missiles act all funky in jousts actually, they much rather track other missiles than planes, which is an odd design decision on gaijins part.

The AIM-54 actually has such a large signature in WT that you can see them in radar when they are launched which is why i think its hilarious people complain that the AIM-54 is hard to defend against. You have multiple different ways to identify and track a launch and determine if its coming at you or not…

iirc the IRIS-T can be set to be directly used by the Preatorian DASS system of the EF2000 as a kind of hard kill APS. If they actually do use at that way, itd need to be pretty reliable at hitting things, like, 80% or even 90%+ imo

Not just Aim-54.

I constantly track all types of missiles on radar in the tornado F3 or Gripen. More than once I’ve found myself manoeuvring to fire on an enemy radar contact only to find out it’s a missile fired by friend or foe. Actually kinda annoying at times.
