North Korea Tests Upgraded Hwasong-11Ma-1 Hypersonic Missile

North Korea’s Missile Administration test-fired an upgraded hypersonic weapon, designated the Hwasong-11Ma-1, from the country’s east coast on September 20, 2026, state media reported, with leader Kim Jong Un and his daughter observing the launch. South Korean and Japanese militaries detected two missiles and measured ranges and altitudes substantially lower than the figures North Korea’s own released flight data displayed, underscoring how far Pyongyang’s hypersonic claims currently outrun independent verification.

What Happened

North Korea’s Korean Central News Agency (KCNA) reported on September 23 that the Missile Administration Bureau had carried out a test of a “new-type weapon” two days earlier, calling it a “significant step in the technological development of its weapons systems” and insisting the launch “did not have any adverse impact on the security of neighboring countries.” State media released flight-trajectory graphics labeled “Hwasongpho-11Ma-1,” identifying the system as an upgraded version of the Hwasong-11Ma hypersonic missile Pyongyang first displayed at its Defence Development-2025 exhibition in October 2025.

According to the North Korean display, the missile flew 908.2 kilometers, reached a maximum altitude of 35.8 kilometers, and stayed airborne for roughly 445 seconds at a peak velocity of 2,146 meters per second, or about Mach 6.3. South Korea’s Joint Chiefs of Staff, however, said it detected two short-range ballistic missiles launched from the Wonsan area toward the East Sea (Sea of Japan), with the first flying about 450 kilometers and the second about 600 kilometers. Japan’s Ministry of Defense gave similar figures — roughly 440 km and 590 km — and estimated maximum altitudes of 60–70 kilometers, notably higher than North Korea’s own claimed apogee. Neither Seoul nor Tokyo has confirmed that the flights matched the hypersonic glide profile North Korea’s imagery depicted, and South Korean analysts have publicly questioned whether Pyongyang adjusted its published figures to present the test as more successful than the raw data shows.

Kim Jong Un, who watched the launch alongside his daughter Kim Ju Ae, called the test “undoubtedly a striking demonstration of ultramodern defence technology” and said the advance would give adversaries “an incurable headache and a very cruel and unavoidable blow.” KCNA described the test as part of “regular activities” tied to an “important weapon system for a specific purpose,” language consistent with Pyongyang’s practice of not officially confirming operational status even after repeated tests.

The Product/System

The Hwasong-11Ma-1 is built on the airframe of the Hwasong-11 family — known in Western and South Korean nomenclature as the KN-23 — a solid-fuel, road-mobile short-range ballistic missile broadly comparable in layout to Russia’s Iskander-M. Rather than a conventional ballistic warhead, the Ma variant substitutes a wedge-shaped hypersonic glide vehicle (HGV) designed to separate from the booster, re-enter the atmosphere, and maneuver toward its target at high speed and relatively low altitude, complicating tracking and interception compared with a purely ballistic trajectory.

Analysts who reviewed the September 20 imagery noted apparent changes to the vehicle’s aerodynamic control surfaces from the version unveiled in October 2025, suggesting an effort to improve gliding and maneuvering performance. The transporter-erector-launcher (TEL) used for the test also changed: North Korea’s original Hwasong-11Ma was shown on a five-axle wheeled chassis, while the September test employed a six-axle vehicle with redesigned protective missile covers, capable of carrying two rounds. It remains unclear whether this represents a standardized operational launcher or a one-off test configuration. The Hwasong-11 family is developed and produced domestically by North Korea’s Missile Administration (formerly the Academy of National Defense Science), with no known foreign co-production or technology-transfer partners.

Who Uses It

North Korea is the sole known operator of the Hwasong-11Ma/Ma-1, as it is for the rest of the Hwasong-11 (KN-23) family. There is no confirmed export activity, and the missile is understood to be intended exclusively for North Korea’s own Missile Administration units. Unverified reporting since 2022 has alleged that earlier-generation Hwasong-11 variants were transferred to Russia for use against Ukraine, though Pyongyang and Moscow have not officially confirmed a hypersonic-specific transfer, and no evidence ties the Ma-1 variant specifically to any foreign deployment.

Export/Procurement History

Because the Hwasong-11Ma-1 remains an in-development, non-exported system, there is no procurement or export history to report. Kim Jong Un’s remarks framed the test as evidence that North Korea has “completed” foundational research into hypersonic missile technology and is moving toward fielding the weapon operationally, but KCNA stopped short of declaring the system deployed or assigning it to specific units, and independent observers have not verified an operational timeline.

Global Competitors

North Korea’s pursuit of a hypersonic glide vehicle mounted on a short-range ballistic missile places it in a field that includes Russia’s Avangard and Kinzhal systems, China’s DF-17, and India’s developmental hypersonic programs, as well as the United States’ Dark Eagle Long-Range Hypersonic Weapon. Compared with those systems, the Hwasong-11Ma-1’s claimed and observed ranges — in the hundreds, not thousands, of kilometers — place it in a shorter-range, more tactical category aimed primarily at regional targets in South Korea and Japan rather than intercontinental strike, more akin in concept to China’s DF-17 than to longer-range Russian or Chinese hypersonic glide systems.

Why It Matters

A functioning short-range hypersonic glide vehicle would complicate South Korea’s and the United States’ layered missile-defense architecture on the peninsula, which is built substantially around intercepting conventional ballistic trajectories. A maneuvering, lower-altitude glide vehicle is harder to track and engage than a predictable ballistic arc, even at comparatively modest ranges. The test also lands amid a broader pattern: it was announced as the UN General Assembly’s high-level session opened in New York and shortly before a scheduled Trump-Xi meeting in Washington, a sequencing analysts frequently read as Pyongyang using weapons tests to reassert relevance during periods of major-power diplomacy.

At the same time, the gap between North Korea’s published performance data and the independent South Korean and Japanese measurements is itself the more consequential story for now. Tal Inbar, a space and missile researcher at Israel’s Fisher Institute, described the weapon as “a very significant weapon, bringing hypersonics to the operational/tactical arena,” while cautioning that “the available evidence is still insufficient to determine how closely the Hwasong-11Ma-1’s actual performance matches the capabilities depicted by North Korean state media.” Until North Korea conducts additional tests under conditions that allow for more precise external tracking, the true state of the program — glide vehicle reliability, guidance accuracy, and genuine range — remains substantially unverified.

What Happens Next

North Korea’s own messaging — Kim’s description of completed research and a shift toward deployment — suggests further tests are likely, potentially with refinements to the six-axle launcher or glide vehicle aerodynamics observed in this iteration. South Korea’s Joint Chiefs of Staff and Japan’s Ministry of Defense are expected to continue publishing their own tracking data after future launches, which will remain the main external check on North Korea’s performance claims. Any move toward serial production or unit assignment would likely be signaled through a military parade appearance or a more explicit KCNA statement, neither of which has occurred as of this writing.

FAQ

What is the Hwasong-11Ma-1?

It is North Korea’s latest hypersonic missile variant, combining the solid-fuel Hwasong-11 (KN-23) short-range ballistic missile body with a maneuverable hypersonic glide vehicle warhead, tested on September 20, 2026.

How fast is the Hwasong-11Ma-1?

North Korean state media displayed a peak velocity of 2,146 meters per second, or roughly Mach 6.3 (about 4,800 mph), though this figure has not been independently confirmed.

Why do South Korea’s and North Korea’s range figures differ?

North Korea’s released data claimed a 908.2-kilometer flight, while South Korea’s Joint Chiefs of Staff and Japan’s Ministry of Defense independently tracked ranges of roughly 440–600 kilometers, a discrepancy South Korean analysts say may reflect North Korea presenting an idealized or extrapolated trajectory rather than the missile’s actual measured flight.

Is the Hwasong-11Ma-1 operational?

No. North Korean officials describe the program as having completed foundational research and moving toward operational deployment, but KCNA has not declared the system fielded to units, and this remains North Korea’s fourth known test event tied to the Hwasong-11Ma line.

Has North Korea exported this missile?

There is no confirmed export of the Hwasong-11Ma or Ma-1 variant. North Korea remains the only known operator, and it is developed and produced entirely domestically by the Missile Administration.
