North Korea Launches Projectile into East Sea on September 20, 2026

On September 20, 2026 North Korea fired an unidentified projectile from the eastern coastal city of Wonsan toward the East Sea. Japan’s Defense Ministry reported that the object landed outside Japan’s exclusive economic zone, while South Korea’s Joint Chiefs of Staff confirmed the launch and began analyzing the projectile’s specifications and flight range. South Korean officials described the launch as a short-range ballistic missile, marking the first such launch in eight days after a similar test on September 12.

The September 20 launch follows a series of recent weapons displays by Pyongyang. On September 12, North Korea fired multiple short-range missiles a day after the United States, South Korea and Japan concluded the “Freedom Edge” trilateral drill. Earlier, on August 29 – September 10, a U.S.–led naval exercise involving South Korea and Japan took place near Guam, which Pyongyang condemned as provocative.

Kim Yo Jong, the sister of leader Kim Jong Un, publicly blamed U.S.–led drills for “ever-worsening” tensions on September 18 and pledged no change in North Korea’s effort to strengthen its nuclear arsenal. In parallel, U.S. President Donald Trump recently ordered a substantial reduction of the annual Ulchi Freedom Shield exercise with South Korea, citing a desire to improve relations with Kim Jong Un.
