Original title: Han Jun: the North Korean hypersonic missile is about three times the speed of sound and is still in the early stage of research and development
(Observer News) as for the test launch of the newly developed "mars-8" hypersonic missile announced by North Korea, on September 29, the South Korean Joint Staff Headquarters announced that the missile is still in the initial stage of research and development, and it will take a long time to be put into practical deployment from the flight speed of North Korea's "hypersonic missile".
According to Yonhap, the missile speed detected by the Korean and US intelligence agencies is about Mach 3 (three times the speed of sound), which has not yet reached the standard of five times the speed of sound of hypersonic missiles. Therefore, the Korean and US study and judge that it is still in the early stage of research and development. At present, only the United States, China and Russia have successfully developed hypersonic missiles.

The South Korean joint staff headquarters said that the military judged that South Korean and US weapons could detect and intercept missiles tested by the North Korean side. However, some people believe that after the DPRK completes the test firing and puts it into actual combat deployment, the interception difficulty may increase. At the same time, the report also quoted an analytical point of view that, given that North Korea's hypersonic missile has entered the test launch stage, it is necessary for the South Korean and US military to improve the missile defense system in time.

For the rare official confirmation by the South Korean army that North Korea has developed a new missile, military sources said that only the contents of North Korea's public reports may cause national anxiety. Therefore, the joint staff explained the current situation.
According to the former Korean Central News Agency, park Zhengtian, member of the Standing Committee of the Political Bureau of the Central Committee of the Korean workers' Party and Secretary of the Party Central Committee, confirmed that North Korea conducted a newly developed "mars-8" hypersonic missile test on September 28. According to the report, through the first test firing, North Korean defense scientists confirmed the flight control performance and stability of the missile in the active section, the guidance mobility and gliding flight characteristics of the separated hypersonic gliding flight warhead. The stability of ampouled missile fuel system and engine used for the first time was confirmed. The test results show that all technical indexes meet the design requirements.
In this regard, the observer network military commentator said that this is the first time that North Korea has confirmed the test firing of hypersonic weapons. Countries have different definitions of hypersonic weapons. Generally speaking, hypersonic weapons refer to weapons that fly at more than five times the speed of sound in the atmosphere. At present, only China has practical hypersonic weapons in the world. Neither the United States nor Russia has officially listed hypersonic weapons.
