Under the guidance of North Korea's highest leader Kim Jong -un, North Korea test newly developed a newly developed sub -fire -type strategic cruise missile on Sunday (January 28).Han Jun believes that from the perspective of North Korea's non -disclosure parameters, the possibility of exaggeration is not ruled out.

DPRK reported on the 29th that Kim Jong-un personally guided the newly developed "Rockets 3-31" sub-fire-type strategic cruise missile testing activity that day.Two cruise missiles flew over 7,000 seconds over the eastern waters of North Korea and hit the island target after more than 7,000 seconds.However, North Korea did not open the missile flight distance, launch a submarine or platform name.

After the first launch of the "Rockets 3-31" missile on the 24th, North Korea did not open the time and distance such as the flight time and distance. It only declared that "the missile is in the research and development stage."

Scholars: The speed of technical progress is too fast to be suspicious

In this regard, Han Jun believes that the same missile needs considerable improvement or development according to the different launch location.Changing the launch platform in such a short period of time is related to the possibility of exaggeration.

Missile expert and honorary professor of the National Defense University, Quan Longxuan believes that after the first test of new submarine missiles in the Mainland, it was launched at sea after four days. The technical progress is too fast and doubtful.

Report also pointed out that Kim Jong -un has specifically mastered the construction of nuclear submarines, implying that the nuclear submarine construction business has made considerable progress.Kim Jong -un emphasized: "Navy's nuclear militaryization is an urgent mission of the times, and is the core requirement for the construction of national nuclear strategic force."

North Korea proposed the "five major national defense core topics" at the Eighth Congress of the Labor Party held in January 2021, namely the development of hypersonic missiles, manufacturing super large nuclear warheads, and increased the precision of strike accuracy within the range of 15,000 kilometers.The development of intercontinental ballistic missiles, development nuclear submarines and submarine nuclear strategic weapons using solid fuel rocket engines.Among them, nuclear submarines are the most inadequate areas of North Korea in the "five major national defense core topics".

North Korea ’s technological progress may benefit from Russian support

Former submarine captain and Professor Wen Genzhi, a professor at Hanyang University, said that from the perspective of Kim Jong -un's inspection, the construction project of nuclear submarines has made certain progress.Perhaps North Korea asked for various technical support to (Russia), and I think there may be progress in this regard.

A high -level section who is unwilling to be named said that the core of the nuclear submarine is a special steel technology that can withstand deep sea pressure for a long time.In order to master this technology, North Korea will actively use cooperation with Russia.

The Central Daily analyzed that the 28th of North Korea's test missiles was to welcome the 75th anniversary of the establishment of diplomatic relations between the North Korea and the second day of the return of the Chinese Ministry of Foreign Affairs, the deputy minister of the Chinese Ministry of Foreign Foreign Affairs, on the 25th.Prior to this, Cui Shanji, a Korean foreign affairs, also visited Russia and met with Russian President Putin.North Korea chose to test missiles on the 28th to show the close relationship between North China and Russia, which opposite the United States.
