In connection with the announcement by the Japanese government of North Korea's launch of the launch vehicle earlier today, South Korea is analyzing whether it is aware of South Korea's decision to stop the ROK-Japan military information security agreement (GSOMIA, GSOMIA).

Japan's Kyodo news agency reported today at 7:24 am that the North Korean government appears to have launched a ballistic missile.

This is 12 minutes ahead of the Korea Defense Ministry announcement (7:36 am).

This year, it is unusual to consider that the announcement of ROK Joint Chiefs of Staff was always faster than Japanese military officials in eight North Korean short-range projectile launches to date.

South Korea detects North Korean missile launches with the Green Pine-class ballistic missile early warning radar and the Aegis' ballistic missile detection radar (SPY-1D).

At this time, due to the curvature of the earth, it is said that more accurate information can be obtained than in Japan at the initial stage such as the specific launch time.

South Korean military officials do not immediately announce that they have confirmed that they have fired, but rather communicate with the US military and conduct some analysis of range, altitude, specifications, etc.

Today, Japan released the North Korean missile launch itself, but South Korea first released specific information on ballistic missiles, altitude, distance, launch location and direction.

It is analyzed that Japan is in a hurry to announce the launch of North Korean missiles, and that the South Korean decision to stop North Korea's decision to stop North Korea's nuclear and missile information is to ease its domestic concerns.

But Japan's swift announcement was possible because North Korea's launch was at an altitude of up to 97 km and the first capture was later than South Korea.

When North Korea fires at a low angle, it is said that the detection of radar in Japan is rarely due to the curvature of the earth.

Japan's request for South Korea to share relevant information under effective Sosmia until November 24 shows that there is a limit to analyzing North Korean missile information with its own intelligence.

South Korea is also in contact with North Korea and is in a favorable environment to capture missiles, but Japan needs help to ensure that information is complete.

The South Korean government reportedly received information about two North Korean short-range ballistic missiles launched on July 25 from Japan.

At that time, North Korea fired two ballistic missiles from the Wonsan Hodo Peninsula in the northeast direction. Due to global curvature, South Korea's ballistic missile radars were known to have limited detection of the end stage.
