North Korea has launched a ballistic missile into the Sea of Japan, with state media describing the exercise as a test of a hypersonic strategic weapon supervised by leader Kim Jong Un.
The missile was fired from the Wonsan area on 3 October. South Korea’s military said it travelled more than 700 kilometres, while Japan’s Defence Ministry estimated a flight distance of approximately 680 kilometres and a maximum altitude of 90 kilometres. Japan said the missile landed outside its exclusive economic zone, with no reported damage to aircraft or vessels.
In a report published on 4 October, North Korea’s Korean Central News Agency said the missile struck a target 1,000 kilometres away. It described the launch as training for troops operating a hypersonic strategic weapon system and said Kim called for continued development of the country’s nuclear deterrent. That claimed distance exceeds the estimates released by Seoul and Tokyo.
Kim Yo Jong, the North Korean leader’s sister, claimed the weapon could manoeuvre at low altitude and incorporated unspecified artificial intelligence capabilities intended to complicate interception. Those capabilities have not been independently verified.
Japan condemned the launch and lodged a protest, describing it as a violation of United Nations Security Council resolutions. Its government directed officials to strengthen information gathering, coordinate with the United States and South Korea, and maintain surveillance for further activity.
The US military confirmed the launch and said it was consulting closely with allies and partners. Its initial assessment found no immediate threat to US personnel or territory, or to allied countries.
The test follows heightened tensions over landmine explosions near the inter-Korean border on 21 September that injured three South Korean soldiers. Seoul has blamed Pyongyang and demanded an apology, while North Korea denies responsibility. South Korean and US authorities are continuing to analyse the missile’s specifications.
