perhaps, but i dont see the missile reaching 40km when it can just about do 25 right now by just improving the loft, its just not there kinematicly maybe im just realy underestimating what loft can do but as far as i know it already does loft to some extend, so finetuning just that … lets just say i dont think any amount of loft would get it to 40km
Old example, but this is a graph of various loft profiles I made for the AIM-54C to prove how substantial a more optimized loft profile can be on the energy of a missile. I did not modify the AIM-54C in any other way beyond the loft profile, and yet, from an 80km launch, the most optimized loft profiles lead to an impact velocity of M2.19 vs the in-game’s M1.5.
That is a 46% increase in impact velocity, simply with an adjustment of the loft.
Now, obviously the SLM will react differently to a change in loft profile due to its specific motor burn, drag, weight, etc… But I wouldn’t necessarily be surprised to see an improved loft profile push it much closer to the 40km range (granted regardless, the missile is underperforming massively according to literally all sources available, so this isnt a silver bullet, its just another potential avenue the gap could be shortened)
I just did some quick ( extremely inaccurate ) calculations:
Under a perfect ballistic loft in a vacuum the missile would reach 40km in 90s and it would need to reach a speed of about 650m/s for that. So we can clearly tell that even in a vacuum the missile JUST about has enough energy to reach 40km under what isn’t really a loft anymore, but just a ballistic trajectory(if it were on a planet with no athmosphere that is)

this is my report btw, but they seem hell bent on staying with the trend of “nothing can be better than a russian equivalent”

AFAIK it’s 80 Hz (80 times per second) which makes sense to me as 24-30 Hz would be way too slow for a high maneuverability missile with TVC.
I also wrote something about DIRCM in the Typhoon thread:

Hey guys I’m pretty new here, the 3 posts I’ve made on the page have been my very first in the forum… like ever. I love playing SAMs if you cant tell from my name lol. But I’ve been waiting and dreaming about the SLM being added to War Thunder for years and I’m absolutely horrified looking at what Gaijin might do to the SLM. I want to start digging but I have no idea what I can do, I’ve never looked for a military source in my life but if I can help you guys at all please let me know what can I do to help. Sorry for being all sappy.

Nyet comrade, don’t you know glorious Russian helicopter DIRCM is impervious to stupid capitalist IIR missiles. (Regardless of IIR being almost entirely resistant to DIRCM IRL)
also, when exposed to DIRCM in HOJ, it would technically be vulnerable to flares too
Incorrect
I stand corrected, iris t is pretty resistant to dircm, however, as the guy said above, other staring seekers on other iir missiles are pretty prone to getting damaged to dircm
They are not. They would have to be in the class of directed energy weapons to defeat IIR systems. Currently that is not what is equipable on a helicopter sized host vehicle
We live in a world where pencil lasers burn camera seekers. while iir seekers in theory could be more resistant, so are the dircm more powerfull than the pencil lasers
No? As opposed to an ejcted flare the signal of the DIRCM doesn’t differ from the registered flight path so the seeker would prioritize it. For the IRIS-T, which would just ignore all scanned lines other than the DIRCM ones, the flares wouldn’t even be visible as they would “spawn” outside its FoV.
An exception would be BOL (the real BOL and not that abomination they are in game) which creates a wall of IR radiation behind the plane. If the missile chases the plane the IR wall would effectively obstruct the view of the missile at the plane, so the IR missile would have to fly through that wall first to lock onto the plane again. That’s why the real BOL is effective against missiles with IIR seekers too. In a tail chase scenario at least. I don’t know the behavior if the missile comes from the front but I would guess it would be like the sun rising behind the plane (IRIS-T having an advantage again here as it can just ignore all lines that don’t show the plane).
Distances and vibrations have to be taken into account too. AFAIK the intensity of radiation reduces with the distance as the laser “divergates” because of particles in the air (dust, steam, etc.). So it loses a lot of power if it has to reach further than a kilometer. Vibrations of the carrier and target platform have to be taken into account too to be able to focus the laser correctly without having to widen the focus point (and therefore reducing the energy transmitted to one point). Additionally you have to point your DIRCM as precise as it gets to hit the seeker head optimally.
So there are a lot of variables to even get the desired outcome of destroying the seeker not even talking about pulse powers and pulse lengths as additional factors and DIRCCM, for example seeker shutoff of the missile, switching to IOG when registering a too high radiation level or a function like variable electrochromatic sun glasses for the seeker or, in case of the IRIS-T, focus another part of the target and shutoff the lines where the DIRCM is located.

If they wanted to make DIRCM “better” they should have added an RNG chance to blind the seeker (based on seeker type), current dev server implementation of DIRCM is laughably op to be honest.
And it blinds IIR seekers on the spikes as well if i’m not wrong, so the only chance the spike and pars carriers had to defend against the Mi-28M is gone, and you know they’re adding a ka-52m next with the same type of DIRCM
Which is stupid. They should implement HOJ mode for IIR missiles already. It’s not even RNG as the DIRCM would act as a beacon for the missile to target.
Problem is we can’t prove HOJ for majority of munitions, i saw 1 video where a 9X block I demonstrated HOJ against a laser DIRCM, i tried searching for IRIS-T HOJ but it is possible that since it has stated “excellent dircm resistance” it doesn’t even need it.
But even if we consider DIRCM completely efective against all ir based seekers, its effectiveness would still be limited to the number of jammers right? I mean, if the heli only have, lets say, 2 jammers it could only jam two missiles at once, but in the videos shown above, it affects all the missiles when you spam them.
That’s the clue of “Imaging”-Infrared seekers. They generate an image which an image analysis software processes. The moment the software registers DIRCM in the picture it gets marked as such and a possible target (like the heat signature of the engine) so HOJ is exactly no different than the normal target aquisition. You could even say all IR seekers are normally operating as Home-on-Jam or Home-on-Blind in this case as they target the emitter source which blinds them technically :D
Well i sure as hell hope gaijin will accept that reasoning.
