The Iranian-backed Houthi group claimed on Sunday to have launched a hypersonic ballistic missile at Israel. While there is no evidence that the claim is accurate, it is clear the Houthis managed to reach Israel with a missile. Its flight path is not known, nor the particulars of its speed, but the Houthis claimed it flew 2,040 km. in 11.5 minutes.

The IDF confirmed some aspects of the Houthi claim. It said that a surface-to-surface missile was fired from Yemen toward Israeli territory, launched at 6:21 a.m. “An initial inquiry indicates the missile most likely fragmented in mid-air,” the military said. The sirens sounded in Israel at 6:32 a.m. – meaning that the flight time the Houthis claimed appears relatively accurate.
This allows for a quick calculation of the approximate speed of the missile: approximately 177 km. per minute. A hypersonic speed is defined as being above Mach 5, or more than five times the speed of sound, that is more than 102 km. per minute.
