SEOUL, South Korea (AP) — North Korea said Thursday that its latest missile tests involved a new hypersonic system aimed at strengthening its nuclear war deterrent, as leader Kim Jong Un continues to build up weapons designed to overwhelm South Korea defenses.

The report by North Korea’s official Korean Central News Agency came a day after South Korea’s military said it detected the North firing multiple missiles from an area south of the capital, Pyongyang, and said they flew about 350 kilometers (217 miles) northeast before falling on land.

The tests came days before world leaders, including U.S. President Donald Trump and Chinese President Xi Jinping, are expected to gather in rival South Korea for the annual Asia-Pacific Economic Cooperation meetings.

The U.S. Forces Korea said in a statement that it was “fully aware” of North Korea’s ballistic launches and also its “relentless pursuit of long-range missile capabilities.” It urged the North to refrain from “unlawful and destabilizing actions” in violation of U.N. Security Council sanctions, adding that the U.S. commitment to its alliance with Seoul remains “ironclad.”

KCNA said the launches involved two hypersonic projectiles that accurately struck a land target in the country’s northern region. It described the system as strategic, implying that the missiles were designed to be armed with nuclear warheads.

KCNA didn’t specify the name of the missile system it tested. At a military parade earlier this month, Kim unveiled some of his military’s newest weapons, including what appeared to be a short-range ballistic system fitted with hypersonic glide vehicles.

North Korea in recent years has been testing various missile systems tipped with hypersonic weapons, which are designed to fly at more than five times the speed of sound. The speed and maneuverability of such weapons are meant to help them evade regional missile defense systems, but experts have questioned whether they have consistently flown at the speeds the North claimed during tests.

Pak Jong Chon, one of Kim’s top military officials who attended Wednesday’s tests, lauded the performance of the “new cutting-edge weapon system” and said the North would continue efforts to bolster its war deterrent and defense capabilities.

During the Oct. 10 parade, Kim also unveiled a new intercontinental ballistic missile that state media described as the country’s most powerful nuclear asset, adding to his growing collection of weapons with potential range to reach the U.S. mainland. Experts say the North could be preparing to test the missile in the coming weeks, ahead of a major ruling party conference in early 2026, when Kim is expected to announce key policy directions, potentially including his approach toward the United States.

Kim has been sharply accelerating the pace of weapons tests since his high-stakes nuclear diplomacy with Trump fell apart in 2019 due to wrangling over the U.S.-led economic sanctions.

Wednesday’s launches were North Korea’s first ballistic missile tests since liberal South Korean President Lee Jae Myung took office in June, pledging to restore peace on the Korean Peninsula. But Kim has so far rejected Lee’s offer for talks and has said he won’t resume diplomacy with the United States unless Washington abandons its goal of denuclearizing the North.
