It carries 9M38M1 missiles that have a ceiling of 46,000 feet.
There's also the 2k22 Tunguskas, which currently can fire its missiles and hit up to 20,000 and the current upgrade under development will hit to 25k or 30k.

Do you have a source? Documentation I see shows 3.5 km (11,482 ft).
That’s going to be more than a stretch for the Tunguska, but the SA-11 can certainly handle it. Not what I’d call cheap, though. Armenia has them, but I don’t know how many.
