hypersonic missiles capable of reaching the U.S.) exponentially.
Despite being remarkable, the JF-22 is not the inaugural wind tunnel globally capable of extraordinary speeds. Numerous others have managed to achieve at least Mach 20 over time. Nevertheless, it seems to be the first capable of simulating scenarios up to Mach 30 — placing it significantly above what is regarded as the United States’ most sophisticated wind tunnel, LENS II, which only attains Mach 7. Furthermore, sources indicate that China’s JF-22 can operate for an average of 130 milliseconds, while the LENS II reportedly has a maximum runtime of 30 milliseconds.
