IRIS-T SLM and Multi-Vehicle SAM Systems!

A swedish source. Devs have the habbit to accept these over everything else.

Its probably why they reduced SLS to just M2. I thought Iris T would be better. How does it look like with the air launched Iris? Also the G overload looks really low. Thrust vectoring and all these fins…and then just 40g. Other sources all claim 60g.

Looks like same situation as pantsir, you wont be hitting brained CAS players farther than 8km.

god I hate mattdawg xD

I mean tbh it claims “>40G” which could be anywhere from 41 to +∞

Theoretically yes.

i know whats gonna happen
its still gonna die miserably to 38mt
and flares and chaff would be enough to dodge all of them missiles
dodging SLAMRAAM missiles is like dodging a normal 120
multi path and chaff
SLM would just be flares and multipath
same with AIO and etc
new spaa wouldnt help
they are even more vulnerable
and given gaijin modeling, on live i dont think they would be any better. UNLESS gaijin pull a “ykw just make CAS difficult to play” and they make them almost and impossible to dodge

Add on top that most maps are insanely small, just imagine 3 or 4 of these at any given time, it will be quite frankly unplayable. Ground as a whole needs to undergo massive changes before systems like these can operate at full efficiency. Maybe an entire new game mode for top tier would be the way to go, with new maps and objectives, etc, etc…

War Thunder’s IRIS-T SLM model critically underperforms real world specifications manufacturer data (Diehl Defence) confirms Mach 3+ capability at altitude requiring at least 250+ kN total impulse to achieve documented 40 km range and Ukrainian engagements: Intercepted Kh-47M2 Kinzhal (Mach 10 capable) at 20 km altitude implies SLM speed > Mach 3 The game’s current 148 kN·s impulse (18.8 kN boost + 5.4 kN sustain) is 60% deficient causing missile to not active even 30% of its capability like how it say it can engage up to 40km but in game can’t even do Mach 1 at 12km

In-Game Performance (From Testing & Screenshot):

  • Max speed observed: ~Mach 1.65 (2021 km/h)

  • Struggles to sustain Mach 1 at just 12–18 km range

                                  **Real-World IRIS-T SLM Specifications (Diehl Defence):**
    
  • Top Speed: Over Mach 3 (≈ 1020+ m/s at high altitudes)

  • Effective Range: Up to 40 km against air targets

  • Total Impulse Estimate: >250 kN·s, required to reach Mach 3+ and 40 km, consistent with a dual-stage boost/sustain propulsion system

  • Seeker: Imaging Infrared (IIR) with advanced ECCM, capable of high off-boresight targeting angles

  • Combat Proven: Intercepted a Kh-47M2 Kinzhal (Mach 10-capable) at ~20 km altitude in Ukraine, implying extremely high terminal speed and tracking performance

The Problem:

  • In-game missile has ~60% less total impulse than real-world estimates
  • Lacks the speed and energy to even reach 30% of its real range
  • Cannot perform realistic long-range, high-speed interceptions
  • Behaves more like a short-range missile despite being classified as medium/long-range in real life

You mean IRCCM? Radar seekers would have ECCM.

Sounds not good :(

Also IR missiles with 2 way DL, you don’t want them to jam your DL

I wonder if we’ll get larger maps so when I spawn in I’m not immediately bombed, targeted or strafed by aircraft.

Lets look at the best ground launched anti air missile in the game.

95Ya6 (Pantsir) vs IRIS-T SLM

95Ya6 20km launch range | IRIS-T SLM 12km (Should have 40km with a radar lock the IR seeker will track when close enough to the target otherwise it uses IOG/2WAYDL to guide the missile towards the target)

95Ya6 5,5kg explosive mass | IRIS-T SLM 4,5kg (Should have around 11.4kg no idea why its filler is halfed in War Thunder)

95Ya6 1,300 m/s with 30 seconds guidance time | IRIS-T SLM 710m/s with 150 seconds guidance time (Should have 1029 m/s (Mach3) with 80+ seconds gudiance time)

Now the part that makes the least sense…
95Ya6 Calibre 90 mm, mass 72.5kg | IRIS-T SLM Calibre 180mm, mass 155kg

How do these stats even make any sense? What type of magic are we talkin about here? I have no idea where they found these stats. Every information I found over the SLM is that the missile has around 127mm in calibre with something around 100kg weight. But it gets a bit confusing here, there is multiple missile for the IRIS-T system aka the SLS, SLM, SLX and HYDEF (which is currently in development). I wonder if they mixed up different missile types or something.

Non of the specs in this game for modern equipment makes any sense anymore (Not all but most). Not even balance wise… But yea I’m sure they got some sort of excuse on why this missile is a marketing lie again and they gonna fabricate some sort of story around it to justify the missile being the worst ground launched IR/IOG/DL missile for its age in the game.

AFAIK that would be the SLS which uses the unchanged IRIS-T missile (127 mm diameter and 88 kg instead of 100 kg) with it’s four stage burn-profile rocket motor.
The SLM has 152 mm diameter (two stage rocket motor with more than double the fuel and more thrust) and weights around 140 kg (according to a swiss interview with a representative of Diehl) while being around 51 cm longer.

SL but what about the SLM. SL could mean anything because there is multiple.

SL was the earlier name of the SLM before it got renamed to SLS, SLM, SLX and HYDEF.

But wasnt the early version the SLS? Thats what I could gather

The SL (now SLM) was the standard variant and the first version to be developed in 2007 AFAIK. Later the SLS was developed as a shorter range option using the default IRIS-T missile. The SLX was announced 2024. So to be in line with the others the SL was renamed to SLM.

At the start there was only IRIS-T (air launched) and IRIS-T SL as the “M” was the only surface launched version. When the “normal” air launched IRIS-T started being used as surface launched they named them SLS and SLM. So SLS = IRIS-T (Air launched) and SL (old designation) = SLM and then newer version after that came as well.
