Here is a short passage to sharing the related knowledge about DF-ZF for you.
DF-ZF，also known as WU-14, is type of hypersonic glide vehicle. Its high-speed maneuverable warhead tests were hold in Wuzhai Missile Test Center in Shanxi Province of China which is completed in the distance of about 250 miles southwest of Beijing (400 kilometers). The speed of the glider is flexible to satellite tracking, flying along the edge of the atmosphere, and finally to the impact areas in western China.
It is said that DF-ZF hypersonic glide vehicle speeds up to Mach 5 to Mach 10, i.e. 6173 km to 12,359 km/h. DF-ZF is a large warhead ballistic missile booster to the edge of space and Earth’s atmosphere, and about 100 kilometers above the ground. After reaching this height, it will begin to pull on and accelerate action to Mach 10, and gliding along a relative flat track. Gliding stage not only makes the complete aircraft aerodynamic maneuvers (e.g. avoid interception), but also increases the missile range. US Defense Department officials confirmed in June 2015, it completed the “extreme maneuver” on the fly during the test. It is reported that there is no means of defense against the DF-ZF as a new type of hypersonic weapons at present.
