North Korea said yesterday it had tested a new hypersonic intermediate-range missile powered with solid propellants, extending a run of weapons tests that’s deepening a nuclear standoff with neighbors and the United States.
With the supposed success of the demonstration, North Korean leader Kim Jong Un declared his country had acquired the ability to build solid-fuel, nuclear-capable missiles of all ranges as he pursues an arsenal that can credibly threaten rivals in Asia and the United States.
But the South Korean military said the North is exaggerating the success of the test and its overall missile prowess.
The report by North Korean state media came a day after the South Korean and Japanese militaries detected a missile launched from near the North’s capital toward its eastern sea.
State media said the test was supervised by Kim, who described the Hwasong-16B missile as a key piece of his nuclear deterrent he vowed to further build up to counter his “enemies,” a reference to the United States, South Korea and Japan.
In recent years, North Korea has been developing more missiles with built-in solid propellants. Such weapons are easier to move and hide, and can be launched quicker than liquid-propellant missiles, which need to be fueled before launch and cannot stay fueled for long periods of time.
North Korea tested a solid-fuel intercontinental ballistic missile for the first time last year, adding to its arsenal of long-range weapons targeting the U.S. mainland. The country also has an extensive lineup of short-range and mid-range solid-fuel missiles that can be fired from land vehicles, ships and submarines and are potentially capable of hitting targets throughout South Korea and Japan. In recent months, the North demonstrated some of these missiles in drills it described as simulated nuclear strikes.
Since 2021, it’s also been testing hypersonic weapons designed to fly at more than five times the speed of sound. If perfected, such systems could potentially pose a challenge to regional missile defense systems because of their speed and maneuverability. However, it’s unclear whether these missiles are consistently flying at the speeds the North claims.
North Korean official media KCNA claimed that during the Tuesday test, the missile’s hypersonic glide warhead reached a peak altitude of 101 kilometers (62 miles) and flew about 1,000 kilometers (621 miles) after separating from the launch rocket, and performed various maneuvers before landing in waters between the Korean Peninsula and Japan.
South Korea’s Joint Chiefs of Staff yesterday maintained its assessment that the missile flew about 600 kilometers and accused North Korea of exaggerating the missile’s flight performance, although acknowledging that the North’s technologies were improving. The previous day, Japan reported a similar flight distance, although its Defense Ministry reported a maximum height close to that claimed by the North.
The Joint Chiefs of Staff said it remains unclear whether the North has perfected the technologies to ensure that the warheads of its hypersonic solid-fuel missiles and intercontinental ballistic missiles survive the harsh conditions of atmospheric re-entry.
“Hypersonic missiles are weapons systems that are still being developed by advanced nations (the United States, China and Russia etc.) and they require highly difficult technologies,” the Joint Chiefs of Staff said in a text message to reporters. “It’s difficult to predict when they will be deployed operationally, but it’s expected to take a considerable amount of time.”
The North also tested a purported hypersonic intermediate-range ballistic missile in January, years after it flight-tested liquid-fuel IRBMs. Experts say such weapons if perfected is potentially capable of reaching remote U.S. targets in the Pacific.
“North Korea’s development of hypersonic IRBMs targets Guam, which hosts U.S. military bases, and even Alaska,” said Chang Young-keun, a missile expert at South Korea’s Research Institute for National Strategy.
Kim Dong-yub, a professor at the University of North Korean Studies in Seoul, said the missile tested on Tuesday was likely different from the system tested in January, which state media didn’t name but was likely the Hwasong-16A. KIM TONG-HYUNG, SEOUL, MDT/AP
