hypersonic during launch phase only, at the target it's more like Mach 3.5 if we're talking about Kinzhals downed by Patriot some months ago
TIL hypersonic is genuinely a distinct word from supersonic.
It's usually over mach 5, but originally it was used to refer to when you start needing to deal with heating up the air.
Also around the point where jet engines kinda just stop working right.
