So, there is actually already a camera target designation mask, i havent messed around with it yet though, might go do that rn actually.

Patiently awaiting the results now lol
Unfortonately it doesn’t appear to, took a while messing around with a bunch of different things, it works for slaving, but DL updates i cant tell if its doing anything or not.
Mmm, decreasing the prolongation time max and lock time out makes the AAM-4’s DL work a lot closer to how it actually should. Having it swap back to DL+IOG basically as soon as the track filter fails.

wrong pic for R-27EA, common misconception that radome should be pointy
also, here is a pic for export variant of R-77-1
for 27ea u can use this, as it would’ve been similar to 27er
@DirectSupport imo you can’t really compare air and ground launched.
For example, I derby er has a max range of 40 km ground launch, same as mica ng. But air launched it only 100km, while mica em is likely much more than that. Ground and air launch are kinda apples to oranges imo.
R77 for example has max range of 12km ground launch but 80 km air launched.
it could be reasonable to assume that the derby er is understated in air launches.

I Derby er example.
Though launch vehicle is subsonic… definitely more than 100km if it’s going Mach 2 lol
Yeah that subsonic launch does explain why it’s understated in frontal air launch ranges, although do note MICA NG is stated at over 40km in ground launch, we probably won’t know the full extent until years later.
The ground launch range doesn’t sound likely.
Yeah you can see here that they’re understating the range (12km??) when it is able to achieve 9km of altitude range. Achieving altitude range is much harder than horizontal range.
Compare it with IRIS-Ts for instance.
I am aware of all of this, the horizontal max launch range is still wrong unless the radar is limited in range itself preventing launches greater than 12km. This isn’t a primary source is it?
Nah it’s secondary… but I don’t think there’s any other mention of ground launched r-77 that still surviving on the internet
Alright, here’s some information on r-77 on how it tracks, datalink, guidance delay, etc. I would assume a lot of other fox 3s employ similar methods as this. This is from the Russian magazine Крылья Родины which the r-77 patent refers to as a reference point for the missile.
Before launch
About 10 seconds before entering the authorized launch zone, the rocket starts operating in “pre-launch mode” and recieves information about the target from carrier.
At the command “start”, the automatic power is turned on, and information about the target is stored in the missile and the fins are unlocked. They are given a preliminary deviation from the carrier in order to safely separate from the carrier.
If located on a rail launcher, then the engine is ignited immediately. If located on an ejection launcher, then the pushrods are triggered first, separating the rocket from the aircraft, and then after a delay, the engine is ignited.
If target is in the case of “minimum range” of when seeker head is to activate, then missile goes active immediately.

During flight
Missile guidance is a combination of both inertial and active radar homing at the final section of the trajectory.
The transition to the latter is carried out by the signal of the on board computer, which determines the distance of the target with the homing head.
After the missile switches to active radar homing, the correction line of the missiles flight data form the carrier continues to form a mathematical model of the target.
In case of loss on the trajectory, a re-searching of the target is done using this model.
In all application modes, the method of modified proportional guidance is used. And in conditions of organized interference, in which the host carrier can provide missile guidance of the direction and approach speeds for the target, guidance occurs along special trajectories.
The missile also employs the ability to passively aim at a source combined with a target.

Thoughts on how this is modeled in wt and general thoughts:
-
IMO, it seems like this missile has contant datalink with the aircraft, even after the missile seekerhead locks onto its target. This should enable the ability to relock the target for the missile if it loses track and if host aircraft manages to keep track of target. Currently, this only happens if the target is in “look down” when IOG+DL will be activated, if target is in look up, it will not use IOG+DL and will simply lose target if they notch it early.
-
The missile loses datalink if the host radar switches radar mode, which idk if irl will make it lose datalink with aircraft, but in WT it does.
-
This missile seems to kinda employ similar methods of datalink like the AAM4 that @Xeno_quaza talks about, unless I am misunderstanding something horribly about aam4
-
It seems like fins should be activated right off the rail in wt when rail launched. IK other missiles like amraam also activate the fins right off the rail IRL when rail launched, but in game all fox 3s seem to be modeled with their ejector launch fin delay.
idk about that, yes amraam is
but that 150-300m is very far
even assuming a 10m/s ejection (which is average to somewhat fast for ejectors) (and g = 10 for easy math)
position function comes out to 2.5t^2+5t=150 which gives and incredibly long delay (almost 7 seconds)
and that is the best case assuming the minimum safe distance listed
that is for proxy fuse not fins
that makes sense, idk why that phrasing confused me
