Neither the Strela or the Type 81 are IIR homing, they are dual mode contrast and IR homing missiles.
They might seem to be the same tech, but they aren’t.
In the game there is a diffrence?
Both “see” image of the plane
I don’t know if there is/would be a difference, because I’m not a developer for War Thunder.
There realistically should be a difference, as for the Strela and Type 81 you have to switch between contrast and IR mode with the contrast mode not working at night or with bad weather conditions, while IIR missiles would always lock on via IR (and/or radar cueing/slaving) and then create an infrared image of the target to distinguish the target from other heat sources.
Apparently the contrast/TV/electro-optical seekers in WT are coded very primitively, so the implementation of IIR seekers might end up being very similar in terms of performance with the main difference being the usability at night and in bad weather.

I don’t think there are any IIR missiles in the game yet (at least as far as i can remember).
The current optical/IR missiles have two modes that you either manually switch between or the missiles chooses the best one for the situation, but once fired they use only the mode they were in when fired, either video mode or IR mode.
An IIR missile effectively use both modes at the same time to get the best of both worlds. Sort of like a “data fusion” between both modes (Not really, but it’s the best way i can describe it).
TLDR: Instead of being only heat tracking it has a “camera” with an optical image of the target but that “camera” only films in IR colors so it sees the world in heat vision and tracks both the heat source and the shape of the plane at the same time. So the target needs to be both hot AND look like a plane (if i remember correctly the missile has a hard drive of pre-trained images on it that it compares with the video feed to know if what it is tracking is a plane/helicopter or something else).
It basically sees this:

Why dont u add the SL version of the missile so we have something that can counter the USSR spam of ICBMs?
.
I just dont get why u refuse to give the rest of the nations things can that match the PANTSIR against the supersonic missiles that outrange everything that can counter it on the ground.
If the guessed leak is right, geemany might getvthe slm 40km range
Thats good news I guess.
I don’t understand people complaining about X and Y nation not getting this and that. You should realise that it’s just a question of time, we will get it all eventually. Have a bit of patience my lads.

There’s a general frustration at the fact that only one nation has been allowed to dominate the SPAA aspect of the game going on two years now. To say better SPAAs are way overdue for everyone…seems to justify the discussions and requests.
Like you might as well brace for it now. If the US gets passed on a more modern SPAA (or equivalent to be competitive) or there’s upgrades to the ADATS as someone mentioned, then theres going to be some backlash.

Spinning rust surviving 100Gs? It’s all stored in flash memory, just a funny observation X)
Hah! Yeah, couldn’t remember the English word so went with the one i could think of x)

i still dont like the fact that 3 nations will have 40 km range sams, that will make every other nations spaa useless, even more drastically than the pantsir did
the pantsir went from 12 km to 20
and most nations had 10-12 at that point
now we are going from 20 to 40
while every nation but russia still has 10-12…
Who is getting 40km range SAMs? So far we have seen one with 12km range and one with 17km range. That leaked SLM launcher for Germany can theoretically launch SLS missiles, so it would be limited to 12km as well.
it can not
They have fitted SLS missiles to the launchers in the Ukraine.
so far that we know from Gsabi and other leakers
IRIS-T SLM (makes no mention of SLS in any way in the leaks)
3½t Truck (SAM-1) (“Type 81 (C)”) with ARH missile
SPYDER AiO (Derby/Python 5 launcher)
different vehicles, germany decided to no get those modifications because they have the boxer iris-t in development
"Combination of IRIS-T SLM and IRIS-T SLS
However, Germany is not only wasting time and resources with this approach, but also wasting opportunities. Diehl Defence has made a number of changes to its air defence system for Ukraine, which were introduced by Ukrainian soldiers based on their experience in the ongoing war. One of these concerns the combination of IRIS-T SLM (Medium Range) and IRIS-T SLS (Short Range).
The SLM and SLS missiles are different. SLM interceptors are significantly larger, but also have greater range and extended capabilities. SLS are smaller, cheaper and identical to those used by fighter aircraft. As Ukraine’s air defence is constantly in a state of emergency, it needs a mix of weapons that is appropriate for the attacker, the ammunition supply and the budget.
Diehl Defence actually managed to combine solutions for both systems within a few months, so that Ukraine can now deploy its IRIS-T SLM in combination with the SLS. Both systems and the combination are not only mobile, but also battle-tested against Russian attacks.
However, instead of recognising Ukraine’s certifications and adopting those systems that have been jointly developed by combat-proven air defenders and industry as a result of war experience, German procurement practice remains the same. And the German plans do not envisage a Ukrainian solution, but an IRIS-T SLS based on the Boxer: The anti-aircraft missile tank (FlaRakPz), which is to be developed as part of the Nah- und Nahbereichschutz (NNbS) programme."
Germany literaly just returned a IRIS_T SLM to diehl because the current crane used in ukraine doesnt fit their safety requirements.
If it doesnt fit germanys plans they dont take it

Spyder AiO doesn’t have to come with Derbys, so it could be limited to the sub 20km range and as far as I know the SAM-1C has 14km of range.
