Chinese scientists and engineers are developing a smart, ultra-small hypersonic glide missile that can be fired from an 80mm (3.4-inch) anti-aircraft gun.
Upon leaving the barrel, the missile reaches a speed close to Mach 6, far faster than a conventional anti-aircraft shell.
This allows it to strike fighter jets or drones more than 20km (12 miles) away, even at altitudes around 10,000 metres (32,800 feet).
Because of its tremendous speed and small size, an enemy aircraft may only detect the…
