North Korea's missile development is complicated, noting that North Korea has announced that it has conducted a "tactical guided missile" launch test on the 17th, pointing out that it uses two types of short-range ballistic missiles properly. It shows the view that it is in the "second cycle" to make it difficult to be intercepted by allowing it to change its trajectory.

The Workers' Party of Korea's Rodong Sinmun, dated 18th, reported that a launch test of "tactical guided missiles" was conducted on the 17th according to the plans of the Academy of National Defense Science, and the Korean media reported that it was a short-range "ATACMS" owned by the United States. He reported the view that it resembles a range ballistic missile.

In addition, the analysis that the "tactical guided missile" launched by North Korea on the 14th of this month is an improvement of Russia's short-range ballistic missile "Iskander".

Regarding this, Yu Koizumi, a full-time lecturer at the Research Center for Advanced Science and Technology, the University of Tokyo, who is familiar with missiles, said, "The" North Korean version of Iskander "has a range of about 700 km, and the" North Korean version of ATACMS "has a range of about 300 km. I think it's possible, "he said, pointing out the possibility that the operating units may also have a division.

On top of that, "I think North Korea was able to try" first cycle "from medium-range to ultra-long-range ballistic missiles in 2017. What we are doing now is" second cycle ", which was intercepted. We are starting to develop missiles that are difficult and can change their trajectory in a complicated manner. "

On the other hand, Koizumi's full-time lecturer said, "The new hypersonic missile launched this month is trying to keep it out of Japan's exclusive economic zone, even though it has the ability to fly quite far." It is said that North Korea is cautiously avoiding the situation of military conflict with the three countries of Japan, the United States and South Korea as it was a year ago.
