First off, Israel is spreading propaganda about the number of hits, second off, Iran has EW-capable, anti-radar, terminal stage maneuverable hypersonic missiles that penetrate ANY air defense.

You first use hypersonics (We even saw video of this) to hit the AA radars, then roll in the cheapo BMs to finish the job.

Basically the only downside to hypersonics is the cost of the damn thing.

Iran is today a missile superpower. Underestimate her at your own peril.
