This can only be done with the missile accepting data in the mid course
No?
IOG doesn’t need mid course guidance

How could it be an IOG shot if no sensor on the aircraft could see the aircraft ?
You know the plane can use data link just not the missile in flight
I think you lack an understanding of how this all works
Not true.
Yeah basically this but ASRAAM
Wingman aircraft gives datalink to launch aircraft carrying ASRAAM > Launch aircraft carrying ASRAAM gives the ASRAAM data from the wingman while it is mounted > ASRAAM is launched and does manuevers heading towards last known position derived from data.
Or just HMD or other sensors like RWR giving initial off-boresight position and then the seeker finds it fast with 90 degree Gimball

I’m not sure HMD itself can provide targeting data though, so if an aircraft is to the rear of the platform (beyond the ASRAAM’s gimbal limits), then I cannot imagine HMD solely can be used to shoot off a shot.
Id have to defer to someone else to confirm, but I cant think of any reason why it couldnt. I assume thats how the F-18 shot was achieved
Better to assume it was datalink. Why would an HMD be able to detect planes itself? It’s not like it features an IRST, radar, or some kind of optical scan to see where a target is.
HMD is able to provide prelaunch coordinates in Azi/elevation. Missile launches with that data, complete a search pattern in the direction of the target and hands over to self tracking.
The missile only needs to turn until the target is within that 180° FoR to be captured by the search pattern.
If you think of it like an IRST without range information (no laser or passive ranging), you’re doing the same thing with your HMD, just providing that positional data. The IMU can do the heavily lifting of what it needs to do to bring the target into view.
Or alternatively if you imagine a BVR launch in LOAL, functionality identical, one is beyond seeker range and needs to fly to be within it, one is out of gimble and needs to turn to bring the target in view.
But functionally we’re talking about a LOAL target, doesn’t matter if that LOAL is due to range or out of FoR, the process prelaunch is the same.

It’s still a bit different than LOAL, since with LOAL you’d assume some form of datalink for course correction.
It’d be closer to MADDOG, such as what some SAM currently have in game, no ?
My main question about using an HMD for such a shot is wether a pilot using HMD, especially when looking behind, would be « precise enough » when looking at a target but without the ability to lock it with IRST or radar to give decent coordinates for such a shot.
LOAL does not need datalink.
It is “Lock On After Launch”, MADDOG is LOAL. The need is for the seeker to aquire the target after it was launched.
It can be done with no pre-launch data, like Tan-SAM Kai (it should provide such data if the launcher has a lock, but Gaijin is yet to implement it), or with pre-launch data, like EldE 98.
HMD is able to provide needed data, that is azimuth and elevation. The missile will then turn, enable its seeker in a search pattern, and acquire the target
HMD is oriented inside the plane, in the same coordinate system. That is why helmets with HMD have a bunch of markers on them.
So the system knows exactly where the pilot is looking, that data is then provided to the missile.
These systems are precise enough, so they know exactly where to display symbology on the HMD, the same applies to aiming.

I’m not doubting the HMD being correctly oriented, I’m doubting the pilot themselves in this case. When looking behind you, you have to use your eyes. You can’t rotate your head a full 180º to look behind and a thus can’t a lock on a target directly on your 6. I would guess the most a human could do would be around 100-120º to the side (so not much more than say the AESA FoR of say the EFT, or SM2)
You can move your torso around the cockpit you know right? But yeah straight to the six is unlikely.
Biology lies
I don’t know the limits of the harness but if you can lean forward enough you could maybe get to 4/5 o’clock? I doubt there is enough freedom to turn to your six though. But its an “over the shoulder shot”.

A human can on average turn its head 180º from left to right. My 220º assumption was counting that as well. Especially in a relatively cramped cockpit and even more while maneuvering and pulling some Gs. I really find it unlikely that the over the shoulder tests were done using HMD, rather using buddy targeting or even some on board systems like RWR.
LOAL simply means Lock On After Launch. Any weapon which locks the target after it is launched counts as LOAL, there is no requirement for datalink guidance. Even things like the Sparrow and Paveway count as LOAL.
