The AIM-120C-7 in the game has a speed of 780 m/s (about 2.3 M). The AIM-120C-5, its closest peer, has a speed of 4.4 M, which is almost twice that value, and the AIM-120C-7 physically cannot have such a low speed, especially in comparison with its previous version. At the same time, the speed of the Soviet 95Ya6 missile on the Pantsir-S1 is for some reason indicated correctly, as much as 1300 m/s. I am not hinting at anything now, but I ask for an explanation of why the AIM-120C-7 has such a low speed.
the aim120c-7 is fired from a 0 0 platform 0speed 0 alt, so it has to use all its power of the booster to gain speed and alt, with results in it having sutch a low speed. but it should be way more than it has now i belive. the pantsir rocket has a strong booster and also a sustaner or how its called. so the pantsir first booster makes the mach 3 speeds and the sustainer keeps the speed up.

u cant compair a aim 120c-7 with is fired from a vehivle on the ground against a aim 120b with is fired while march 1 or more from a plane

i think i can, because it is indicated as max speed overall, not counting such factors as place of launching, etc.
also i believe we can surf the internet and find some materials where aim120c-7 had speed more than 2.3 M despite the fact that is has been launched from a spaa
its launchd from a humvee thats why its says 780ms thats are the stats for the aim120c-7 when its fired from a humvee
Max speed is one of the most misleading stats in the stats card. To quote a technical moderator who commented on this bug report as an example:
Max speed depends on many things, including the speed of the carrier, air density and altitude. So max speed in the stat card doesn’t really says anything. The actual in-game max speed may be more or less than in stat card, depending on circumstances.

The rocket motor physically does not have enough energy to even get the missile to Mach 4 in a vacuum, so that Mach 4+ topspeed is indeed for an air launched scenario.
You can see in the missile spreadsheet that the AIM-120C-7 only has a dV of a bit less than 900 m/s, which means it’s not enough to even go mach 3 (at least at sealevel conditions) even if it experienced 0 drag. It would require negative drag to go any faster. Engine performance wise, it seems fairly correct. Rocket fuel mass is correct and specific impulse of HTPB fuels are around 250s, so at most maybe it’s very slightly underperforming, but not enough to get it to mach 3, and especially not mach 4, from a ground launch configuration.
I don’t claim that the missile can develop incredible speeds with the help of twists (unless, of course, the Soviets have them), but here the question arises: why does the US have an anti-aircraft system delivered in the early 2000s, and the Soviets have a Pantsir delivered in 2012, which is stronger than the American anti-aircraft system.
and still it seems to me that in the game the Soviet missiles are stronger than the American ones, or at least this is the impression created, especially when you see 780 m/s against 1300 m/s, here the psychological effect already comes into play - maybe I would not have written this post if the game had indicated a different speed value, closer to the real one.
It should be in no way Mach 4 when launched from a stationary site BUT it shouldn’t be close to the AIM-9X in terms of speed. They both go the same speed now and that’s weird
The C-7’s speed is correct. Any bug reports will be correctly dismissed.
C-7 goes mach 4 when launched at 12,000 meters altitude going mach 0.9.
