That’s classified if I remember correctly. But that is the most logic and practical way how this missile will work. Since everything staged and done by system after being launched. What operator do just press fire button.
Putting two and two together tells that Gaijin got the missile entirely backwards, the lock range is reduced the closer a target is due to turbulence and heat effects on the seeker, the full lock range is unlocked once the booster phase ends and the seeker is in range of a target which is 10 or so kilometers.
Spoiler


I honestly have no idea how Gaijin came to the conclusion that the IIR seeker that has 10 to 20 km of target acquiring range IRL can be castrated to just 4 (IN ALL SCENARIOS), when we know for a fact that the aerodynamic cap jettisons the moment the missile enters the terminal phase which is when the booster ends and the full range of the seeker is available to the missile.
Gaijin can simply code some logic that if the booster is still active the cap jettison range is 4 km away from the target, once the booster ends the cap jettison is increased to 10 km away from the target. That’s fair.
so are we just gonna forget about this change ?
Yea, we’re screwed once again and about to be screwed 1 more time in the upcoming update.
Put on your BDSM suit and wait, since you chose to play germany.
What else can be done? SMIN1080P has been contacted multiple times, and each time he has ignored the problem. Gaijin refuses to fix it.
These stats are basically a lie now, there is no scenario where the seeker will activate at 9 or 12 km, for all intent and purposes this change made the seeker 4 km in “all aspects” which is worse than Stingers or AIM-9Bs from the 60s

And of course you can get spawned camped by BUK (specially in flat maps because of the massive warhead that does splash damage) or SAMP-T and now Type 03. Long range shots are now a thing of the past for IRIS-T, most engagement distances barely exceed 10 or 7 km, so your standoff range is basically the same range they have to kill you in return.
However…
It does feel like they made IRIS-T more “reliable” and by reliable I mean 1 in every 8 shots will connect with a Mi-28, I’ve also noticed that some missiles fly entirely on Datalink.
This might have been Gaijin’s “improvement” to IRCM, to make the seeker not actually work so that IRIS-T behaves more like a SARH missile. It is still bullshit tho, having to rely on RNG should not be the case (are we DCS IRCCM now?), there is no consistency.
So either your missile flies entirely on Datalink for some god-damn reason, or you thread the eye of the needle by hitting the blind spot. Great.
Either way, I’d much rather have the lock range nerf reverted, screw IRCM “improvements” you neutered this SPAA to basically Stinger SHORAD status, the seeker is more than capable of acquiring and tracking target at distances greater than 10 km.
The problem was it was a 40km IR missile that gave you nearly no warning other than a single ping on the RWR compared to the SARH missiles. First week out it was brutally oppressive to uptier into.
Ah yes the “?” is pinging me on the rwr, life is fine.
Wrapping that nerf in an “IRCM improvement” buff is silly. If it WAS intended as a buff, it was absolutely overtuned.
9 km front aspect lock range was fine, but 4 km is just insanely bad. The missile can activate its seeker when it enters a range at which it can reliably lock a target (at least IRL)
They could’ve coded some logic that if the booster was still active then the seeker activation range is 4 km away from a target, once it is in its terminal phase the seeker activation range is 10 km away from a target. It is just extremely annoying having to guide the missile for so long and having no guarantee it will begin tracking with IR.
Also, air-to-air Datalink seems to work just fine, but ground-to-air Datalink doesn’t really work the same way, the game has no recollection of what the missile was previously targeting when radar contact is lost and regained, I’ve had missiles just fly past planes that were lost and reappeared in the radar screen, but the missiles simply don’t change course.
The only “buffs” we can hope for is if DL is lost the missile goes on IOG+SRC, aka the missile will look for a target on its own with its seeker, and Datalink for the terminal IR phase, currently once a missile tracks a target on its own, Datalink is lost, this should help it not lose track and/or defeat LDIRCM.
Me when CLAWS AIM-120s
I suspect there’s plenty of issues with ground radars and their implementation. DL being one of them.
GJN broke it intentionally, this change achieved the result they wanted. To make the IRIS-T SLM horrible. So why would they acknowledge any feedback about it?
