The Wu-14 Hypersonic Jet launched from an Intercontinental Ballistic Missile System travels at Mach 10 on the Edge of Space carrying Nuclear Warheads
This craft, known as the Wu-14 travels between Mach 5 and Mach 10 which is somewhere in the vicinity of 3500 and 7400 Mph. Sources say the hypersonic vehicle can travel up to 9,000 Mph! This means circling the Earth in 2.5 hours. At this speed, the vehicle can out maneuver any missile system currently active.
If the vehicle was launched from a sub or aircraft carrier in one of the oceans, then a strike to nearly any country would happen in just a couple of minutes.
The WU-14 “threatens to neutralize US strategic missile defenses with the unique capability of flying at ultra-high speeds and maneuvering to avoid detection and tracking by radar and missile defense interceptors.”
