Popular Science reports that China’s developing a hypersonic weapon that has triple the range of existing Chinese air-to-air missiles. The new missiles rely on a ramjet engine that may have a speed of at least Mach 5, or 3,835 miles per hour.
All this could mean greater range, maneuverability, and speed for missiles that are being mounted on Chinese stealth fighters like the J-20 and J-31.
This is nonsense. The engine is only one factor affecting the ramge of a missile. At higher speeds, the range drop rapidly.
