I agree and to add on, RWR needs to be less sensitive. Friendly plane’s missiles trigger the RWR, enemies lock your friendly and fire at them but you receive the lock and fire ping, even though your friendly is not that close to you.
So all three of those primary sources say the maximum launch range is up to 80 km.
Presumably that means the best it will manage is 80 km under ideal conditions? It certainly makes me doubt the claims that it was capable of 100 km launch ranges.

This is a limitation of battery life
Maybe so, but it still makes claims of 100 km range doubtful.
Also if the range is up to 80 km wouldn’t that mean it has to be for a high altitude supersonic launch against a supersonic target? Because it is essentially saying that 80 km is the highest possible firing range.

The maximum range is limited by many parameters
Battery life, ensuring minimum G, ensuring minimum speed to hit a target, etc.The rocket can fly at least 200km away.But due to the boundary conditions it is limited to 80km
Yes, but if the missile has a battery limited range of up to 80 km that is presumably for a high altitude, high speed, launch.
If the missile is fired at a lower speed, or lower altitude it’s average speed will be lower meaning it covers less distance during its battery life.
Also is the battery life of R-77 80 seconds like AMRAAM?

This applies to absolutely all missiles.Aircraft-based range is always indicated from a high altitude and speed
I can’t say for sure
Yes, so to me the quoted 80 km range seems likely to be high altitude Mach 2 launch against co-speed / altitude target (seeing as it is “up to 80 km” the 80 km figure must be for best case conditions, with less range under other conditions).
In that case AMRAAM likely has better range than R-77, as it is said to have 92 km range when fired at Mach 1.6 / 35,000 ft against a co-speed / altitude, target.

The speed of the target is not stated, only the speed of the carrier.usually these are aerial targets in the USSR, the LA-17 was used with subsonic speed
Either way it seems unlikely that the R-77 is hitting an 80 km target from a sub sonic launch, like I’ve seen people saying.
The target is subsonic, not a carrier
How is a target subsonic at such high altitudes, why would they even test that tbh.

12-14km may well be a subsonic flight
We’ve already discussed this, is this some kind of bait? We know the R-77 to have 80km range under similar circumstances to the AIM-120A’s 74km figure. Likewise, both can exceed 100km with higher speed and altitude launches.
Let’s not forget that the R-77 does so WITHOUT lofting.
When we last discussed R-77 performance you said:
I took your word for it at the time. Today I was wondering what sources were available for the R-77, so looked though the sources section and comments in this thread and quickly found three primary sources saying range of “up to 80 km”.
To me “up to” implies 80 km is the maximum range the missile could possibly hit a target, which would be extension mean for a high altitude Mach 2 launch.
Hence my confusion: what information points to 80 km being for a subsonic launch?

Those same sources state the R-27ER/ET to have “up to” a specific range figure which we know isn’t their actual maximum range. Simply put, it wasn’t translated well to English and it isn’t “up to and not exceeding…”
The reasoning for it being 80km on subsonic launch is because when testing in-game my AIM-120 model matches known data points within a good margin of error (5-10%) when the known public data is used. When I do the same for the R-77 it exceeds the 80km datapoints in the same conditions as the AIM-120s 74km launch unless it has quite literally double the drag coefficient.
what were the conditions for the 74km range?

The same ones you refused to send us as a “source” when you claimed I was wrong… until you realized we already had that source. Verified by a couple of other places as well.
No, the other source you and Flame and Gun job all have.
