True, in any large-scale missile volley, saturation can challenge even advanced systems. However, there are multiple open-source indications suggesting that Iranian hypersonic or quasi-ballistic missiles did indeed challenge and in some cases bypass—layered defense systems. The mention of SM-6 is relevant because, while it's not confirmed to have been deployed in this instance, it remains part of the broader Aegis Ballistic Missile Defense capability often cited in deterrence discussions.
Even if no direct hit on an American warship occurred, the fact that Iranian missiles reportedly penetrated multiple defense layers still points to a notable vulnerability. It’s not necessarily about one system failing, but about the combined strain on all layers when facing coordinated, highspeed attacks.
It’s also important to note that the United States deployed THAAD batteries to Israel precisely because systems like Arrow 3, while capable, are not fully equipped to counter newer hypersonic threats on their own.
