Here is a rough calculation for Gokdogan's effective range.
I read in f16.net, the time it takes for a BVR missile to lose 25% of its velocity after burn out at supersonic speeds.
*Never @ > 100,000 m (~300,000 ft) ; in space
*150 seconds @ 24,000 m (~80,000 ft)
*70 seconds @ 18,000 m (~ 60,000 ft)
*25 seconds @ 12,000 m (~ 40,000 ft)
*10 seconds @ 6,000 m (~20,000 ft)
*5 seconds @ Sea Level
Now if Gokdogan is launched at supersonic speed it will achieve Mach 4+ near hypersonic speed.
Let's say a TurAF F16 flew up to 15,0000 meters and launched the Gokdogan at supersonic speed in a lofting trajectory. (To maximize the effective range)
You can see in this Gokdogan test firing video, the nose cone of the F16 is angled at 30-35 degrees upward w.r.t white skyline below.
So, in this case Gokodgan will cover roughly 10km in the boost phase before the rocket motor burns out.
And then it will likely to continue climbing upward in a lofting trajectory. Hence slowing down the velocity loss.
By the time it losses 25% of its velocity and descends to Mach 3, it will probably be 90-100km away or more you get an idea. For an accurate estimate you need to do the math) while still retaining roughly 30G Maneuverability.
Now that it will come down on the target from above in a lofting trajectory, it means, outmanoeuvring it would be relatively harder than if it were to come from any other angle.
On a side note- If above mentioned missile's velocity properties are correct, then it kind of explain, why USA isn't that bothered with not having the best BVR weapon or some countries despite having the chance to get Meteor for its Eurofighter fleet are still buying AIM-120D. (Germany recently requested to buy 969 AIM-120 C-8/D. Or Qatar bought AIM-120 with its Typhoon Trench 3A along meteor) That is probably because, when maximizing the Altitude and speed advantage of Eurofighter (or even better F-15EX with a maximum altitude of 20000m) and launched upward in a lofting trajectory, the effective range of AIM-120D and Meteor does not wildly differ as much as we previously thought.
However, Meteor (or any ducted rocket missile for that matter) will have game changing ability when launched at low altitude like 4000-6000 m where conventional missile losses 25% its velocity in 10 seconds or less. (Plus Meteor will always have superior end game maneuverability due to its multiple pulse motor hence also maximizing the kill probability)
