SEOUL, South Korea — North Korea launched multiple ballistic missiles toward waters off its eastern coast on Monday, regional defense authorities said, accelerating weapons demonstrations following a recent high-profile military test by South Korea.
South Korea’s Joint Chiefs of Staff reported that projectiles of several varieties were fired from around Pyongyang, an area that includes the capital city’s main airport, long utilized as a key missile launching venue. South Korean military spokesperson Jang Do-young said at least one missile traversed more than 559 miles before plunging into the sea, though military officials did not disclose the total number of projectiles detected.
Flight Details and Hypersonic Suspicions
Japanese defense officials offered further flight data regarding Monday’s activity. Japan’s Deputy Defense Minister Takashi Koyari stated that at least two missiles flew roughly 17 minutes apart and splashed down outside Japan’s exclusive economic zone, with no damage reported by the prime minister’s office, according to reports from Al Jazeera and the New York Post.
Koyari detailed that the initial projectile covered approximately 137 miles, while the subsequent missile traveled more than 565 miles along an irregular trajectory, prompting Japanese defense analysts to suspect it may have involved hypersonic technology. Jang told reporters that South Korean analysts were evaluating whether North Korea had tested hypersonic systems during the launches.
South Korea’s presidential national security office condemned the launches, stating that Pyongyang’s recurring ballistic tests breached United Nations Security Council resolutions and demanded an immediate halt to the provocations.
Rival Missile Demonstrations
The missile firing took place days after South Korean President Lee Jae Myung observed his country’s first flight trial of a domestically produced hypersonic missile, designed to fly beyond five times the speed of sound. Lee’s administration described the technology as vital to bolster conventional military capabilities and deliver surprise strikes against priority regional targets, CBS News and NBC News reported. Al Jazeera reported the test took place on Thursday, while other outlets reported it occurred on Friday.
Jang noted that North Korea’s launches appeared designed to sharpen technical missile capabilities while presenting a direct counter to Seoul’s recent hypersonic trial. On Oct. 3, Pyongyang conducted its own launch of an intermediate-range hypersonic weapon intended to bypass missile defenses in South Korea and Japan, according to reports.
Alongside tests of advanced missiles, North Korea has conducted live-fire exercises and introduced a new naval warship in recent weeks as leader Kim Jong Un continues to promote his country’s nuclear arms program.
Border Tensions and Diplomatic Stalemate
The weapons activity unfolds amid worsened cross-border friction following a landmine explosion in the Demilitarized Zone that wounded three South Korean troops. A joint probe by the South Korean military and the U.S.-led United Nations Command determined the mines had been placed by North Korean personnel, an assessment that Pyongyang dismissed while rejecting Seoul’s demands for an apology.
The rising hostility presents challenges for President Lee, who assumed office in 2025 promising to revive dialogue with the North while simultaneously developing domestic conventional military strength to reduce reliance on the United States. In August, Washington scaled back a major combined military drill, with President Donald Trump pointing to his personal rapport with Kim.
Formal nuclear talks between Washington and Pyongyang have remained frozen since a high-stakes summit collapsed in 2019. Kim has characterized South Korea as a permanent adversary, and Pyongyang maintains that diplomatic engagement cannot resume until Washington drops its denuclearization prerequisites and ends what the North describes as hostile policies.
South Korean and Japanese defense authorities said they are continuing to track military activities in North Korea and analyze sensor data from Monday’s launches.
