I thought they could do only FL100
AFAIK US Stinger has some 8 km range, Soviet Strela some 9 km, and when I served the army (30 years ago) I operated improved version of this missile produced in ex-Yugoslavia that had effective range of 12 km. I’m not into weapons and I don’t know anything about recent development of such missiles but moving at 2 mach and with 12 km of effective range this weapon can reach relatively slow aircraft at some higher altitude.
Any more pics, @eal?
