Thsts where ur wrong lol.
Smaller projectiles are affected more by drag because they have less inertia.
The sustainer, (i admit im not sure which part of the missile it is in) does not sustain a high speed for long but rather a high speed up to around 10km which is the stated irl maximum engagement height of the pantsir’s 20km ranged missiles.
10km altitude means it maintains an interception worthy energy state up to that point.
It stands to reason that after 10km either vertically or horizontally, the sustainer will have died out a while ago or the remaining projectile will be flying only on inertia and momentum.
I’m unsure of what you mean by any of this.
The booster is meant to rapidly pick up speed for the missile and the sustainer is there not to speed it up in the same way as the booster,
but to make it loose speed slower.
This by design going to keep the missile at a higher speed over a short distance compared to a much larger missile with a longer sustained burn.
It’s like comparing a marathon runner with a 100M sprinter
Yes.
Thats why its called the sustainer.
It sustains the speed/velocity.
However to say that the SLM dies out around 15km altogether while the pantsirs missile can go on upto 18km is an unfair assessment
Especially for real life where it is capable of 40km
You need to practice and get used to that, and that is the only thing I can tell you. Sometimes they are much more effienciy than other IR AGMs, especially there are tons of SPAA
