The missile has been reported to be based on either a shortened Hwasong-14 first stage, or a Hwasong-12. [7] [12] However, the distance between the verniers and the main chamber on the motor suggest that the base of the missile is the Hwasong-14, as it has a slightly longer gap between those.
Comparison of Ballistic Missile and Hypersonic Glide Vehicle (C-HGB) Flight Trajectories for the LRHW Program Scramjet-powered hypersonic cruise missile. A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as above Mach 5, or above 5 times the speed of sound.
The AGM-183 ARRW ("Air-Launched Rapid Response Weapon") is [5] a hypersonic air-to-ground ballistic missile planned for use by the United States Air Force.Developed by Lockheed Martin, the boost-glide vehicle is propelled to a maximum speed of more than Mach 5 [6] by a rocket motor before gliding toward its target.
The missile effectively surfs on its own hypersonic shockwaves, generating lift without the increased drag that wings create. The U.S. tested similar designs on the experimental X-51 from 2005 to ...
Strictly speaking, a hypersonic missile could describe any weapon that exceeds five times the speed of sound—i.e. traversing a mile per second—but practically, the term applies to two modern ...

North Korea did not name the missile that had the first stage to be used in this test, instead, depicting it as "an intermediate-range solid-fuel ballistic missile" and claimed the test was a success, while South Korea and Japan claim the missile exploded before releasing any warheads.
However, the missile allegedly failed to actually achieve hypersonic flight, with South Korean intelligence determining it only reached Mach 2.5-3, whereas hypersonic weapons are considered to travel at a speed of at least Mach 5 (1.7 km/s; 6,100 km/h) although actual data on the flight was not publicly released.
