if we assume 93° they will only start overlapping 50m away from the helicopter
but the inverse square law is a thing
and at 92° they will overlap 75m away from the helicopter
at 91° they will overlap 150m away from the helicopter
and it haveing coverage at 50m and beyond is what matters, as to safely divert a missile with proximity fuse you need to engage it fairly far away
Do we know at what distance the DIRCM engages on these helicopters? At least in the game files?
iirc around 500m to 1km

that is under the assumption that it can even gimbal that far
my guys this is basic geometry
how is it supposed to fire a laser throgh the opaque housing
sure but we dont have that ingame sooo

that image makes it hard to tell if it can gimble that far or not
but think of it like this, what design constraints would prevent them from allowing the system to gimble far enough to cover direct front
because there isnt any good reasons for them to not be capable of doing so

plus for all i know, it could turn out to be a CM dispenser
this is it here
as we can see, the max depression from the normal appears to be 90 degrees
SS from
turns out this is a normal DIRCM. not a laser based one
oh and its dutch
that shows it can angle past 90 degrees? with potentially somewhat reduced effectiveness
look at the axis of rotation and the edge of the housing
some of the lens might be blocked by part of the laser should still be visible well past 90 degrees
no the CIRCM is the laser one
But yeah, all in all, the only thing that’s needed is for the system to rotate 90° and then the eye to provide 1 more degree for it to be see at 150m frontally which is well within engagement range for these systems. Seems logical enough with the information we have that it has overlapping bubble front and back.
even if true, still wont protect against IRIS-T since it has HoJ capabilities so

To get the bubble down, how does it work? Does the entire sphere inside rotate to make the block moving +/- 90° face downward-upward? Cause if there’s no rotation of that type, the coverage would be worse at the bottom and up despite providing full frontal/backward protection.
same with like all modern IIR missiles
we all know that LDIRCM is overpreforming in game
the issue is that due to how strong SLM is gaijin had to add it at this level to make helicopters usable
there is not exactly a sphere inside.
think of it as a tank turret with seperate horizontal and vertical drives
just as in tanks, the gun cannot depress into the physical body of the tank
the issue with this is that, contrary to even my understanding a few moments ago, the laser is not emitted from the turrets
it is merely directed. the emitters are actually deeper inside the fuselage as it isnt possible to generate such level of intense lasers in such a small aperture like area
there is another system by northrop grumman on other AH-64Es which employs a different design
this might have more than 90degrees of elevation, but this is called the LAIRCM
while the CIRCM of the current Apache E is not so capable in traverse
