Proof of LDIRCCM capability in IIR against Laser DIRCM

If it has a songle point of origin, it can be homed on.
Your argument presented no logic.

And fyi a laser is more akin to a flashlight than a lamp.

Well good luck with that it’s not lamp or flashlight to be source of dispersed light and any deviation could result in quite distance between you and target.

are you trying to make me lose braincells??


invert missile direction and place the seeker at the front

tell me what do you get??
when under effect of LDIRCM, IIR guided SAM accuracy increases inversely proportionally to distance

Good post. I believe that Slavik magic LDIRCM rays will be fixed.

Looking at which kind of posts he likes to engage with, in combination with what nation and specific vehicle he plays mainly (Bonus points if you guessed its an undertiered Heli) and how many sources he posts alongside his claims, you should probably know everything you need to know.

Its the classic “oh it shouldnt be fixed because it currently benefits me” all over again

Directed InfraRed Laser CounterMeasure systems

How they work

There are 3 DIRLCM systems in game currently (excluding the one on the Mi-8AMTSh-VN)

  1. CIRCM

CIRCM operates by emitting an InfraRed Laser Beam that matches the aircrafts natural exhaust Infrared profile. This laser beam is generated inside the main module and sent to the turret module which directs it towards the incoming threat. (A similar IR signature is utilised in order to try and fool the incoming threat to think that the decoy signature is the real target)

Since the natural/standard IR signature of an aircrafts exhaust CANNOT burn through or even damage a simple pre-modern IR seeker, damage to a modern state of the art Imaging IR seeker would be impossible. Hence a dazzling method is used in order to, try, to saturate the seeker and cause it to miss. Other methods include attempting to mislead the seeker away from the aircraft however these are yet to be researched into as to how they work or even IF they work.

As is seen on the first post, dazzling with a low power IR laser beam does not cause permanent damage to an IIR seeker and the seeker can maintain target tracking using the many algorithms at its disposal. (FT, HOJ etc)

Source(s) are listed below:

  1. L-370V28-5LE Vitebsk-5 (Export version: President-S)

Main components of Vitebsk:

  • L370-1 control unit
  • L150 “Pastel” Digital RWR, 1.2- to 18-GHz range, 360° horizontal and 60° vertical
  • L370-2 IR/UV warning sensors
  • L140 Otklik LWS
  • L370-3S digital active jamming station (planned for use against Radar guided threats)
  • L370-5 DIRCM / L370-5L LDIRCM/ L418-5 LDIRCM, stated range from 500 to 5000 meters (not specified for which of the 3 systems this belongs to)
  • UV-26 CM launcher, 32 rounds per pod
  • Towed Radar decoy (for fixed wing aircraft)

The known specific configurations are L370E31 (Ka-31), L370V50 (Ka-50), L370V52 (Ka-52), L370E8 (Mi-8MT), L370E26L (Mi-26), L370V24 (Mi-24), L370V28 (Mi-28), L370K25 (Su-25).

In the files, the system is named as L-370V28-5LE, since it is a Russian helicopter, it is possible that the E should not be listed as it is a domestic version rather than export (Vitebsk-5 rather than President-S).

The brochure for the President-S system states: “The laser optical-electronic suppression station is designed for individual protection of helicopters from guided missiles with infrared homing heads.”

Reading carefully, we can understand the following:

  1. The system uses a laser for optical-electronic suppression
  2. It is designed for use against missiles with IR homing heads.

Now there is no mention of Imaging IR seekers. But lets put that to the side for a moment. The brochure mentions IR guided missiles, which means, to decoy such a missile, the Laser must operate in the IR wavelengths. We can even be specific, that for SUPRESSION of IR guided missiles, a laser is used.

No mention of seeker destruction, no Imaging Infrared seekers, no mention of seeker damage even.

Source(s) are listed below:

  1. Z-10ME DIRCM (name unknown, information needed)

Assumed to operate similarly to CIRCM

@tripod2008 has also written a pretty good analysis in his comment here, he also points out how it is not explained how the LDIRCM (and even a normal DIRCM) can decoy the UV seeker channel of SAMs like the Stinger.

Another thing to note is the power of these systems. As stated on the brochures, the CIRCM and Vitebsk systems draw a maximum of 545W and 3500W respectively. However there is a problem with the latter value. According to the brochure, it is 3.5KVA which cannot be converted into Watts without the specific power factor (determining system efficiency).

Regardless, both of these values indicate power draw. As when such systems need to be integrated into vehicles with limited fuel and electronic power supply, the power draw is one of, if not the first question to be asked.

Secondly, only the CIRCM brochure actually indicates maximum power draw by the laser generator (before inefficiencies eat away at the output power) as 250Watts. The Vibetsk does not indicate the power draw specifically for the laser generator.

That you think IIR will ignore any ECM and fly straight to the target.

And what ? This topic about IRIS-T being able to shoot down everything at once. Is this one is better that what ever you painted on me ?

Pretty much what I got from this too knowing very well these missiles are toned down for balance, they always have. I do want to see these weapons get dual-plane maneuvering though.

You knew who you were talking to

Well pantsir wasn’t nerfed, wasn’t it? So only your side is allowed to ground all CAS?
With how advanced CAS has become - release version of IRIS-T was a pure bottom feeder.
If you were killed by IRIS-T before it means that you either constructed your gameplay wrong or you’re a kh-38 slinger, which is a baseline skill issue. We all know who you are. ru mains yearn for handouts.

What side ? This is about LDIRCM vs IRIS-T and it contains China, America And Russia.

And what this whatabotism has to do with anything at this moment ?

It’s about you having no sense of your surroundings and complete misunderstanding of reality.

Hmmm devs siad don’t think LDIRCM only works at IR wavelegnth because that is only teminological thing but here we are Nth topic about LDIRCM works only in IR, seems to be because me having no idea of reality and surroundings.

Buddy, you sound barely coherent.

Well no wonder this is Nth topic about LDIRCM works only in IR

It will just like how an arh will ignore ircm

IIR won’t be unaffected by ldircm but it won’t be decoyed by IR either

No thats just me calling LDIRCM an ECM because i think it fits for it.

Basically for now reason.

I think we’ve pretty much proven that at least for the CIRCM and Vibetsk-5, their specific LDIRCM is incapable of decoying IIR missiles.
