Right, I forgot about manpads on helicopters. Yeah the DIRCM works against them, unlike IRCM. Though if you manage to lock the Ka-52 from > 1km with a missile that uses the tracking suspension type IRCCM, the missile is able to at the very least take an inertially guided flight path to the target, so if the Ka-52 (or Mi-28NM, being the only other with DIRCM I think) doesn’t change directions, they might still get hit through proximity.
I suppose having DIRCM is still quite useful then. Though point still stands, unless you are having near knife fights with a helcopter essentially, attaining IR locks on them is pretty hard to begin with, especially when they have HIRSS and are facing you. But yeah, in case of helipad camping it works well, against their IR missiles and not their gun if they have it ofc.
I’ve done a test against Stingers recently, and there was no difference in lock range between HIRSS and no HIRSS.
Some helicopters without HIRSS actually had a lower lock range than those with HIRSS.
So there’s a lot of IR inaccuracies with helicopters at this time.
Did you test on the same helicopter with and without HIRSS or on different helcopters, on the Ka-52 (or Mi-24s) you can for instance just turn off the module. If tested on different helcopters, tests might be inconclusive because of different engine IR signature and configurations. But without a doubt, the IR lock ranges can be indeed very inconsistent
It does work. The ka52 had a bug 2 updates ago, basically if you installed the MAW, HIRSS would be removed (now its fixed) but I played a lot without it. It’s noticeable, I saw manpads firing from longer than usual ranges.
Two Things I noticed from a Russian and NATO cross section of the Ka-50 is that the KH-25 missile used is the KH-25MP, not ML, which is a modular ARM. Also, the use of the A-T-A missile was the R-73, not R-74.
See cross sections:
NATO CS
Soviet CS
Now, this is the Ka-50, not the 52, so, just my assumption that it would continue to use the same/upgraded weaponry of the Ka-50, but I’d have to find a Ka-52 CS.
Something fairly new, I’ve not seen that specific modification of it before. Would anyone else like to see the different versions come to the game, and be foldered with the “original” one to the game?
Sorry if I introduce myself into this discussion, even if it doesn’t have much to do with it, but the new Italian Fenice helicopter should also have the DIRCM, do you think it is the same as that of the KA-52, or is it some more advanced model, furthermore for my complete ignorance, how many helicopters in real life and in game use DIRCM???
Maybe start to read some Think Thanks studies, etc. I do not relly on youtube, facebook or any other social media as a source of information. I am old school, reading articles, books etc. Try google, and some good question, he will find something to read for you. But even you should understand that , 40 Ka52s were not shootdown all by heavy machinegun, or ATGM launcher.
There is definitely a weakness in DIRCM, I can imagine it works on longer ranges, like 3-4km + , but at close range the system maybe does not have time to react. In this game DIRCM is modeled, that it does not even wait for launch of the missile.
The thing is that the DIRCM shouldn’t effect the Stingers with the POST seeker(FIM-92B and later & MIM-72G), for a few reasons.
The use of the UV channel which is well outside the Laser’s bandwidth, so provides a guidance channel that should be unimpacted by the projected jamming signal.
The Seeker’s response to some types of countermeasure is to switch from a Rosette pattern to Conical scan and so reduces the FoV as well as the ability to blank a channel’s guidance input and push ahead like the AIM-9M pending countermeasure detection, which in later variants can be reprogramed, which alters the required jamming signal to defeat.
Ability to use a IR/UV Contrast channel for extended range (by the strictest definition it isn’t Photo-contrast due to Rosette scan being a *pseudoimageing technique *, since it’s a single detecting element[ in the POST seeker’s case it’s a twined co-axial detector ] that is procedurally scanned across a scene)
Abstracted from various excerpts from the following patent;
L370 works in UV wavelenghts on top of IR. iirc it was advertised as this and also a videos of dual seeker missiles getting jammed exist to back this up.
Those likely only work against flares instead of DIRCM. The only debate left is if IIR seekers are actually immune to it, as there isn’t much information available
