The Hezb never talks about its air defense system. However, once, a commentator close to the Hezb said on Lebanese TV that the Hezb had the Iranian version of the Russian S-400 (reverse engineered) and that Hezb members have been trained on it. This commentator is not too reliable and no one from the Hezb ever mentioned any of this. So I don't know how much credibility to place on this. That was a few years ago during Corona when I watched a lot of TV.

In any case, the Hezb certainly has the ability to destroy all airports including military ones so that if planes go on a mission, they have nowhere to land.
