“Its a lot easier to overwhelm” he says with 8 strelas firing at him simultaneously and it still took like 6 volleys before they managed to hit him …
Also want to point out they seem to have MASSIVELY increased the range of LDIRCM. Used to work at 500m, now it seems to be jamming things 3km out lmao
Oh and also, he was only using 1 of the 2 emitters, so yeah, a single IRIS-T, even with its TEL’s located at opposite sides of a map firing simultaneously likely will never be able to take out the AH-64E and Z-10ME. Might have a chance against the Mi-28NM now, MAYBE.
Also want to point out that this just reinforces the fact that when the Su-57 comes, it will be totally immune to IR missiles if this is how LDIRCM remains. Absolute joke of a “rework”
They just did the meme, they copied the existing MUSS code from the Puma and added to it to DIRCM sentries. But blatantly disregarded everything about the “DIRECTED” feature of the whole laser system.
So like I said, nothing really changed. The only scenarios where this might work is if a helicopter is being engaged from multiple directions and missiles are approaching it from different aspects, which is absolutely never going to happen.
An IRIS-T TEL engaging it from single point is totally hopeless as all missiles within the FoV of the sentry will be jammed, and there doesn’t appear to be any “cooldown” delays either, so spacing your shots does not seem to help.
I was hoping this would allow for say, shooting a Brimstone at a Mi-28 to trick the DIRCM to jam the laser munition, followed by AIM-9M behind it which is going to get there faster and proxy on it. God forbid we have strategies and skill expression in this game.
is it even possible for a laser to jam 2 missiles even if they come from a similar bearing ?
My understanding of what a laser is is screaming bs
Unless the laser beam is 50m wide of course, but considering the size of the device on helos, I have my doubts
Not much of a laser at all at that point lmao. Laser beam divergence should likely be well below 1°, ESPECIALLY if its decoying missiles out past 3km like it seemed to be doing in the above video…
So who wants to do the math? A laser with a few kW pulse power getting its laser beam spread over 10.816 m² applies what power to the 5x5 cm big missile sensor? I guess it will be milliwatts lol :D
Edit: Yep, it’s 2,3 milliwatts for a 10 kW pulse laser, not nearly enough to jam anything.
Also: As a laser usually has a really tiny point it focusses its energy, it has to be extremely precise against all the odds (vibrations, moving target, air turbulances, spread by atmospheric particles and the air itself, etc.). Hitting a 10x10 cm target at 500 meters the laser would have to be directed as precise as 0,0057° against all these aforementioned odds, a little less precise if you calculate in the spread of the laser cone but that also means less power at distance.
The problem here: You can get either precise or fast or have to do extreme mechanical investments (like multiple steps, one cardan, one/two piezo mirrors, etc.) to get something usable. You also have to pinpoint the targets location extremely precise/with an extremely low margin of error for the orientation to be precise.
This is all simple physics, just logical thinking is needed, no need for “sources”.
I just watched the vid. It doesn’t seem DIRCM is practically nerfed. When you consider the ammount of incmoing missils @ several waves, there is still no practical way to shot down these choppers. Cause they shot back as well and the launcher won’t live long enough to launch that many missiles.
Also the question arises what the logic might be behind this? How can a tiny and narrow laser affect that many lined up missiles? It should be blocked somehow.
As I didn’t want to calculated all those values myself, I outsorced my thinking and put it into a spoiler. The target size is 25 cm² for a 5x5 cm sensor. The laser has a beam which spreads to 10816 m² at 3 km.

52 mW at a seeker at 100 meter distance from a 250 W laser with that beam spread… Not enough to damage anything, most likely not enough to really blind something too, but perfect if you go by HOJ (home-on-jam).
Edit: But also the “200/250 W” for the laser are continous power draw (how much the board power circuit has to supply) and not the power of a single pulse. If you stretch the pulse intervals to 1/10 of the time, you can generate laser pulses with 2 / 2,5 kW power.
It’s just the report showing the IRIS-T SLM missile’s real weight being 126kg.
Apologies for not clarifying, a different source other than a video showed the IRIS-T SLM as “>M3”, and that was forwarded. Just was saying that devs should know about the IRIS-T SLM being greater than mach 3 even before this video came out.
