Iris-t slm

Experience is not only tied to public matches, you should know that.

Again, handwaving arguments that doesn’t suit you by using “skill issue” is funny.
Pantsir was a great addition, others not getting something similar is a shame though.

Pantsir was terrible addition when no other nation had similar systems, especially when most planes didn’t event have RWR that could detect K-Band.

Even now Gaijin nerfed upcoming Spaa’s so bad that they cant even perform at their 30 percent capacity compare to real life.

Like it or not Pantsir is more than capable of dealing with enemy units even from +13Km’s, if you can’t do it then it’s on you, not on system.

Heard enough… Nerf IRIS T make the missile Mach 1 and let in only pull 10 G with a max range of 4 km and Buff Pantsir

if u want the truth its going to be better than irl in game , why ? cus everything its going to intercept in game is going to be supersonic most of the times , irl it was mainly used on subsonic cruise missiles (mach 0.5-0.85) that fly in a straight line or in a easily predictable pattern. what u can argue about is that its lacking in terms of kinematics. but i thin they will buff it later on , even with a kinematic nerf it will still be good.

that looks like stinger

heard enough Buff all the vehicles and Planes on the Russian Techtree and give Pantsir immortality for realistic balance reasons.

Remove every Ammo for the western Tech trees
and Buff KH38 even more

and last but not least Nerf EF 2000 and Iris t and nerf everything for a 5th time

Ito and Flakrad have awful radar elevation, and even if they manage to lock the 38, it’s a dice roll whether the VT1 will proxy
ADATS is not allowed to lock the Mach 2 missile coming straight at it, and it’s not allowed to cue its IR lock to a radar track anyway
Otomatic is even less likely to proxy on the Kh38 than the VT1, but to be fair its proxy fuze rarely works against any munitions
Type 81 missiles also lose track of Kh38 once they burn out

It’s almost as if bias is real… nah we need a couple more years of 90% russian queues and Kh38 + Pantsir + helis immune to IR missiles before that’s a possibility

its funny you call it “it only used against cruise missiles”, “its better in dev server right now than it is in real life” maybe you see it is been used against cruise missiles ,only becasue russia knows if they send a fighter jets to iris t’s envolope,it is not coming back.
please dont cluther this forum we don’t really need someone trying to prove it is bad with no evidence at all.

when did i say its bad ? also slm has much less range , if fighters do end up getting within their range , patriots will be used not SLM. patriot has much more range than SLM. both pac 2&3 patriots have much more range than SLM.

holy shit, are you sherlock holmes?
because thats just, woow

an system which is designed for bigger distance has more range than an system for medium range?
no way, not possible

Indeed

Didn’t proxy, didn’t detonate.

Now, tihis is from 1 month ago, but I doubt very much it’s been fixed.

sorry to tell you, but thats fixed on dev…

The I must be missing the misiles completely then, because more often than not they don’t proxy on them sadly. :(

Mavericks, no problem. Hellfires, no problem. Vikrs? No problem. These things… more often than not nope.

Edit- missed the part where you said on dev. Just hope it’s not like the stomer thing where they said they fixed and just… didn’t.

It was and still is a great thing to have in the game. Only thing that had a chance to fight back against CAS.

If you can’t dodge it’s missile from 6-7-8km and up, then it’s on you, not on the system.

Damn do I love using skill issue arguments…

If u can’t see it on RWR then I guess partially acceptable. Not being able to see it immediately when launched is a bit painful tbh.

I already send this on the Rumor topic but i will send it here to

Since we have what we could call a SAM situation, so i decided to do some testing and i used Gemini and asked him the following:

Spoiler

we have a missile like IRIS-T SLM (same shape of SLM with aerodynamic cap and everything else), the missile can utilise thrust vectoring control, this missile is lunched at 90 degrees just like the SLM, this missile have complete weight of about 155kg, have diameter of 180mm and length of 3.4m, this missile also have a weight of 115kg at end of the booster burn and weight of 92kg at the end of the sustainer burn, and the burn time of the booster is 5 seconds and sustainer burn time is 10 seconds.

If this missile have an effective range of 40km and effective altitude of 20km and have a maximum not effective but maximum range of 50km and maximum service celling of 25km (altitude) how much velocity will it need to achieve this range, and how much thrust the booster and the sustainer will have to generate to reach that range? keep in mind this missile was tested, and they found out that it can successfully hit a maneuvering target at a range of 30km (not it’s max range) and 12km of altitude (not it’s max altitude) in almost 60 seconds.

And got this answers (this is the entire answer with equations and complete explanation):

This is a small summary too:

Spoiler

Missile Performance Summary
To hit its targets, your missile, similar to the IRIS-T SLM, needs some serious speed and power!
How Fast Does It Need to Go?

  • For its effective range (40 km) and altitude (20 km), the missile needs to reach a top speed of about 900 to 1,050 meters per second (around Mach 3 to 3.5).
  • To achieve its maximum range (50 km) and highest altitude (25 km), it needs to be even faster, hitting speeds of approximately 1,100 to 1,200 meters per second (around Mach 3.7 to 4).
    How Much Thrust Does It Need?
  • The booster, which gets the missile off the ground quickly, needs to generate a powerful thrust of about 20,400 Newtons (20.4 kN). That’s roughly enough force to lift over 2 tons!
  • The sustainer, which keeps the missile going after the initial boost, needs to produce a continuous thrust of about 5,870 Newtons (5.87 kN). This is crucial for maintaining speed and reaching higher altitudes.
    These powerful engines allow the missile to accelerate rapidly, overcome air resistance, and climb high enough to intercept targets far away.

Some clarifications and my personal opinion about this:

Spoiler
  1. This is something for a bit of fun plus to have a general understanding about the math and physics behind this issue plus what characteristics the SLM need to reach the quoted range.

  2. This is not to be used to make a bug report this is just for discussion and even if used it will ofc not be accepted.

  3. The approach behind this that i didn’t ask directly about the SLM rather than made the theoretical missile and told it its similar to SLM with all the exact ingame values, so the answers will be less basis and bit more authentic, and these are the sources:

  1. Gemini calculations seems to be a highly accurate plus almost realistic too but it seems it have some problems in conversion from m/s to Mach so be easy on him in that regard.

  2. Funny enough Gemini calculations when it come to thrust seems to be close to Gaijin assumptions about the SLM thrust and i will guess that Gemini might be abit more accurate for example:
    The ingame booster thrust is 18,800N Gemini sed it need to be 20,405N with the difference being almost only 1,200N for the ingame sustainer thrust it’s 5,405N Gemini say it need to be 5,870N with the difference being almost only 330N.

  3. Now the difference it no that big in the end when it come to thrust but that’s still a problem when it come to a max range of 50km but it’s not the problem that limit the missile from achieving the effective range of 40km.

  4. The real problem is the acceleration and gaijin hard lock of top speed and acceleration of the missile since it’s locked on 710 m/s almost M2, which will make the missile not even able to achieve an effective range of 15km, which Gemini in here suggests that the missile need a speed no less than M3 and say it will need a top speed between M3.5 to M4 to achieve the maximum range of 50km and 25km in altitude.

  5. How to fix this simple just increase the top speed and possibly the thrust too, there may be some problems in flight characteristics and performance but i didn’t include these calculations like drag and other things to make it less complicated.

  6. Will increasing the burn correct this problem, well the answer is no if the missile keeps the 710 m/s since it will not reach the 30km and 12km altitude in the time recorded by the test which is nearly 60 seconds, so unless acceleration is correct along side thrust increasing brun time won’t be that effective.

  7. In the emd this is just a discussion, that’s all the points i have and if anyone is interested feel free to share your opinion. Thank you

As player who grind entire German TT using FlarakPz and FlarakRad couple of years ago (I’m still trying to enjoy current FlarakRad situation but I can’t). The reason most SPAA not trying to shoot down KH-38MT because in many case they are oftenly launch more than 1 KH-38 (and in many case Russia have more CAS in the game). So instead being died to missile that you don’t know it comes to you or not (many SPAA dont have TWS), it will be much better to hiding then pray not die to one of them. And wait for their CAS come to your direction (normally I prefer to engage at 6-8km and pop my smoke while at same time guiding my missile from inside smoke).

The issue is delta V here, SLM is ultimately an IRIS-T, for which it weighs around 60kg without fuel, and then a scaled up motor section. Somehow the empty weight for SLM is 92kg. If we account for the larger motor section shroud etc… the empty weight of SLM is likely ≈70kg. That would be an extra 22kg of fuel, and less weight.

This would give it a delta V of ≈1450-1500m/s, now we can really hit some high speeds!

Next is the drag, its current cD is 1.75, however given it is modelled with its full caliber along the full length of the missile, it should have a much lower cD compared to other missiles. It also has a wind shield for its first moments of flight before reaching lock range. So should be treated as an average between that of an ARH and IIR missile.

Yes that’s a long time, but I haven’t optimised the loft profile yet. And that’s a lot better than it was.
