I’m going to assume that is against a non-maneuvering target though, the extra weight and G limit of missiles like the R-77-1 will act against it at range more so than something like the AIM-120A, that may be how a missile like the AAM-4 is balanced, it weighs significantly more than the R-77-1 or PL-12 which are missiles that already weigh much more than AIM-120s, MICAs and Derbys
I do believe that even the R-77-1 would underperform against the AIM-120 at range and that kind of leads me back to the original point that they really need to fix the drag issues first, the R-77 needs to find a middle ground between the MICA and AIM-120, it shouldn’t have the range of the 120 as it pulls harder, but it should have more than the MICA as that has thrust vectoring.
In its current state the range is mostly fine without maneuvering but as soon as it turns it bleeds way more speed than it should
yeah, you’re right.
another point we could make is let’s say time to 20km range at 5km alt and 1.0M
Derby - 46 sec
R-Darter - 45 sec
R-77 - 44 sec
Mica-EM - 44 sec
R-77-1 - 37.5 sec
PL-12 - 37 sec
AIM-120A/B - 33.5 sec
AIM-120C-5 - 32.5 sec
AAM-4 - 32.5 sec
we can also look at how much speed missiles have at that time:
Derby ~ 120 m/s
R-Darter ~ 124 m/s
R-77 ~ 135 m/s
Mica-EM ~ 130 m/s
R-77-1 ~ 160 m/s
PL-12 ~ 180 m/s
AIM-120A/B ~ 220 m/s
AIM-120C-5 ~ 225 m/s
AAM-4 ~ 230 m/s
You can imagine how much difference that would make trying to hit a moving target as well, you could probably dodge most of those missiles kinematically but much less likely for the top 3
I wonder what it would look like if you brought it down to 15 or even 10km
at 5km alt and 1.0m time to 15km and speed at impact:
Derby ~ 22.5s and 240m/s
R-Darter ~ 22s and 250m/s
R-77 ~ 23s and 250m/s
Mica-EM ~ 21.5s and 260m/s
R-77-1 ~ 20s and 310m/s
PL-12 ~ 20s and 325m/s
AIM-120A/B ~ 19s and 360m/s
AIM-120C-5 ~ 19s and 370m/s
AAM-4 ~ 19s and 365m/s
No Darter is ever making a shot past 20km…They weigh more than the Derby.
Unless that aircraft is flying right at you at mach 2.0 then maybe. But all they have to do is just turn slightly and the missile is trashed.
As was already said the max range of the Darter is about 24km, that is from 5km altitude at Mach 1 against an effectively static target, by 20km the missile is only traveling 120m/s which is slower than most propeller aircraft and therefore wouldn’t be able to hit anything manoeuvring, the stats shown are the perfect kinetic statistics, not their practical effective range
Darter is one of the biggest disappointments, it pulls great G and its fast off the rail. Close range shots it massively over leads and corrects, It just flies straight into the ground or loses the target. They are comically easy to avoid while Aim120 and R-77 take some real effort.
