North Korea said it was a newly-developed mega-cannon of the projectile shot on the East Sea yesterday. Emphasizing that it is a weapon that is not in the world, we cannot rule out the possibility that it is a different weapon system from the three types that have been tested recently.

The projectile, launched by North Korea, is called a newly-developed ultra-large cannon and was released with a picture of Kim Jong Un.

[Korea Chosun TV: (Kim Jong-un) was thrilled to see the great militant power of the super-armor gun weapon system.]

Its length and wing shape are similar to the new large-caliber maneuvering cannons launched earlier this month.

However, the peak altitude was three times higher than the new large-caliber maneuvering cannon and flew up to 160 kilometers further.

The same is true with the two-row mobile launch pad, but some say that the number of launchers is smaller, exceeding 400mm in diameter.

[Shin Jong-Woo / Senior Defense Analyst, Korea National Defense Security Forum: In the case of China's 400mm large-caliber guns, the range is over 400km. If the caliber is bigger than this, we can say that North Korea has developed a cannon that can be used in all of South Korea.]

Although it may be an improved version of the existing gun, it is called the super-large and emphasized the first test shot and the birth of an unprecedented weapon, and it is impossible to exclude the possibility that it is a weapon system different from the three missiles and guns.

It's also worth noting that the projectile's top speed is over Mach 6.5 to missile levels.

Although the cannon has smaller warheads than short-range missiles, they have less destructive power, but they are more difficult to defend because they are fired in large quantities toward a specific target.
