supersonic

This term describes a specific physical threshold where an object breaks the sound barrier, creating a sonic boom. It carries a connotation of extreme power, cutting-edge technology, and immense velocity, typically associated with aerospace engineering and military aviation.

In a figurative sense, the word is occasionally used to describe something that happens with incredible speed or efficiency, though it remains primarily a technical descriptor. It is distinct from hypersonic, which refers to speeds significantly higher (typically five times the speed of sound) than the supersonic range.
