a missile deadzone is covered by the gun. The overlap might not be perfect but it certainly beats not having a gun at all.
Yes, indeed comparing CS/SA5 to SLM will make the CS/SA5 look bad. I already stated that SLM overshadows any AA system we currently have. But you proposed to lower it to 11.7/11.3 and as such im comparing it to AA systems found at 11.7.
Ito90M and SLM both share BR of 12.0, should Ito90M be lowered to 11.3 also as VT1s are also overshadowed by SLM?
As much as might currently enjoy the mental damage SLM seems to inflict to the CAS players, I ultimately think it shouldnt stay at 12.0 where it stomps 11.0 planes. And i also think Ito90M shouldnt go lower.
they are faster, yes, but you paint it as if thats only thing that matters.
VT1 has booster with burn time of 3.5 seconds and no sustainer (albeit little shy of double the thrust of FB-10A), while FB-10A has burn time of 4 seconds AND 10 second sustainer. Meaning it should maintain its speed better than VT1 over longer distances as FB-10A is also lighter than VT-1 (65kg vs 73kg).
and no gun
That is not true. VT1s have relativley large deadzone. Not because the missile has bad pull but because if the missile leaves a guidance cone, it will stop tracking alltogether. Meaning against close range targets you cant effectively track them unless theyre coming at you or away from you.
You know what would be great to have in such scenario?
A gun.

in which way? as mentioned above, FB-10A has sustainer unlike VT1.
sure, as long as you have line of sight.
and a gun.
and missiles not having to rely on LoS.
issue not unique to CS/SA5, SLMs radar is also bugged to hell and back.
see the sustainer mentioned aboe.
just like VT1.
issue not unique to the CS/SA5. VT1s are affected all the same.
OSA has burn time of 3.7 seconds with 13.5 second sustainer. OSA has more powerful booster but FB-10A has more powerful sustainer.
that is indeed truth, i give you that.
issue sadly not unique to the CS/SA5. SLM missiles also fail to intercept incoming AGMs but thats due to server tick rate.
bad gun beats no gun.
guidance issues are not unique to the CS/SA5. SLM also has those, it also doesnt like to switch to IR terminal under certain conditions. IRIS-T has those. Just scroll few posts above to the video @Phoenix_RX01 posted.
see the booster vs sustainer above.
bugs not being fixed is not an issue unique to any nation.
I did not.
