North Korea has released imagery of what appears to be a flight test of an updated version of its Hwasong-11Ma hypersonic missile, nearly a year after the weapon first appeared publicly at a military technology exhibition in Pyongyang.
The September 20 test involved a short-range ballistic missile (SRBM) booster fitted with a hypersonic glide vehicle, according to photographs released by North Korean state media. A display screen visible in the imagery identifies the weapon as the Hwasongpho-11Ma-1, or Hwasong-11E-1 in the equivalent English-language designation.
The test was conducted from the east coast near Anbyon County, south of Wonsan, an area North Korea has repeatedly used for missile testing. The launch site allows missiles to be fired eastward over the Sea of Japan, providing a relatively controlled area for testing short- and medium-range systems.
South Korean and Japanese authorities say they detected two launches on September 20, with the first occurring at approximately 3:00 p.m. local time and the second several hours later.
North Korean photographs show the missile being launched from a coastal location, with Kim Jong Un and senior missile officials observing the test. Kim’s daughter, Kim Ju Ae, also appears in the imagery.
North Korea displayed a mock-up of what it called the Hwasong-11Ma at its Defense Development-2025 exhibition in October 2025. The design uses the basic architecture of the Hwasong-11 family, known in the West as the KN-23 family, but substitutes a distinctive glide wedge-shaped vehicle for the conventional warhead arrangement.
North Korea claimed another hypersonic missile test that same month, but did not release launch imagery clearly connecting that test to the Hwasong-11Ma. The missile was subsequently shown again during a military parade in Pyongyang.
The latest “-1” designation suggests an iterative evolution of the Hwasong-11Ma, although Pyongyang has not explained what modifications it represents.
Based on the imagery, the new configuration also includes a modified launcher, with the missile carried on a six-axle transporter-erector-launcher (TEL). When the Hwasong-11Ma was first shown, it was mounted on a five-axle TEL. The latest vehicle also appears to incorporate modified retractable covers around the missile.
It remains unclear whether the new TEL represents a standardized operational vehicle or a test configuration.
As with previous North Korean weapons announcements, the country’s state media claims need to be treated very cautiously. Pyongyang has a long record of publicizing weapons systems and test results that cannot be independently verified, while some of its purported hypersonic tests have left outside analysts unable to determine whether the advertised maneuvering performance was actually demonstrated.
Perhaps the most revealing test-related imagery comes from a display screen photographed at the launch site.
Kim Jong Un and his daughter can be seen watching the screen, which shows the apparent flight trajectory of the Hwasong-11Ma-1. The displayed path initially follows a ballistic trajectory before descending and then performing a pull-up maneuver, regaining altitude before continuing toward the target area.
That type of trajectory is consistent with the basic concept behind a hypersonic glide vehicle. The booster provides the initial velocity and altitude, after which the unpowered glide body follows a relatively shallow, atmospheric flight path at hypersonic speeds, while maneuvering rather than following a simple ballistic path.
The graphic is useful for understanding what Pyongyang says the weapon is designed to do, but it does not independently demonstrate that the missile actually followed the depicted trajectory.
The flight data visible on the display provides some unusually specific figures.
According to the North Korean imagery, the missile traveled 908.2 kilometers (564.3 miles), reached an altitude of 35.8 kilometers (22.2 miles), and remained in flight for approximately 445 seconds, or 7.4 minutes.
The display gives a velocity of 2,146 meters per second, equivalent to roughly 4,800 mph. That is hypersonic velocity in the aerodynamic sense, but speed alone is not what makes a hypersonic glide weapon particularly challenging to defend against. More consequential parameters include sustained controlled flight, maneuverability, guidance, and accuracy.
Other portions of the display appear to show additional points along the flight, including different times, altitudes, and speeds. None of these figures have been independently verified.
The claimed range is particularly noteworthy because it does not match the publicly reported tracking data from South Korea and Japan.
South Korea’s Joint Chiefs of Staff said North Korea launched two SRBMs from the Wonsan area on September 20. The missiles were assessed to have traveled approximately 450 and 600 kilometers, respectively.
Japan similarly reported two launches, assessing the first at approximately 440 kilometers and the second at approximately 590 kilometers, with maximum altitudes of roughly 60 and 70 kilometers.
Those figures are substantially different from the 908.2-kilometer distance shown on North Korea’s display.
The discrepancy does not necessarily establish that either side’s data are incorrect. The North Korean figure could represent a different measurement of the flight path, or could correspond to a portion of the test that was not reflected in the public South Korean and Japanese assessments. It is also possible, if not highly probable, that Pyongyang selectively presented or altered the data.
South Korean analysts have already raised questions about the unusually long distance displayed by North Korea. Yonhap reported that experts suggested Pyongyang may have altered the figure to portray the test as more successful.
Regardless of the range actually achieved in this test, the Hwasong-11Ma/Ma-1 is significant because it represents an attempt to combine a relatively compact SRBM with a maneuvering hypersonic glide vehicle.
The underlying Hwasong-11 family is a well-established North Korean missile design. In its KN-23 configuration, members of the family have also been used by Russia against Ukraine. By placing a glide vehicle on this type of booster, Pyongyang could potentially give a regional strike weapon a flight profile substantially different from that of a conventional ballistic missile. The Hwasong-11Ma/Ma-1 also uses a solid-fuel booster, allowing for faster launches than earlier liquid-fuel designs.
In principle, the Hwasong-11Ma/Ma-1 could give North Korea an additional hypersonic strike option against more heavily defended targets in South Korea. Having road-mobile TELs would also provide greater operational flexibility despite their relatively limited range, while making it more difficult for adversaries to locate and track the launchers.
A genuine boost-glide weapon creates significant challenges for defending forces since the sheer speed of the weapon bypasses most air defenses. Its trajectory can also become less predictable after the boost phase. Maneuvering at lower altitudes could also reduce the time available to detect, track, and engage the weapon.
However, the available imagery does not establish the extent of the vehicle’s maneuverability, its ability to maintain controlled flight, its accuracy, or the reliability of the complete missile system.
North Korea has made similar claims about its hypersonic weapons in the past.
Pyongyang says it has flight-tested multiple hypersonic boost-glide vehicle designs since at least 2021, but there continue to be questions about what degree of actual capability the country has achieved in this regard. Viable wedge-shaped boost-glide vehicles have historically been extremely difficult to design and then bring to an operational state.
The challenge is not simply reaching hypersonic speed. A weapon has to sustain controlled flight and maneuverability under extreme thermal loads, while also overcoming demanding materials-science, guidance, and navigation requirements. The terminal phase is harder still. Accurately finding and striking a moving target, particularly a ship, requires a highly capable seeker and guidance system. Integrating a nuclear warhead introduces another layer of engineering and weapons-design challenges.
Those demands have made hypersonic weapons a major technological challenge for the United States and other major powers. China is currently widely regarded as the leading country in deploying and developing operational hypersonic systems, although important questions remain about the capabilities and maturity of individual weapons.
Pyongyang said it first flight-tested a wedge-shaped hypersonic glide vehicle in 2021 aboard the liquid-fuel Hwasong-8, before pairing a similar-looking vehicle with the solid-fueled Hwasong-16B intermediate-range ballistic missile (IRBM) in 2024.
In its coverage of the latest test, North Korean state media initially avoided identifying the weapon, describing the event as a successful trial of a “new-type weapon” that it said was significant for the rapid development of weapons technology.
Kim said the development would give adversaries an “incurable headache” and deliver what he described as a “cruel and unavoidable blow.”
Tal Inbar, the head of the Space and UAV Research Center at Israel’s Fisher Institute for Air and Space Strategic Studies identifies the Hwasong-11Ma/Ma-1 as a “very significant weapon, bringing hypersonics to the operational/tactical arena and [posing] a challenge to … air and missile defense systems.”
Whatever the exact achievements of the test, the imagery points to continued development of a weapon North Korea first publicly displayed nearly a year ago. The appearance of a new, six-axle TEL, a potentially modified missile, combined with the apparent flight test, suggests that the Hwasong-11Ma/Ma-1 program has progressed since its initial public unveiling.
What remains uncertain is how much of that progress represents a genuine improvement in operational capability.
The latest test therefore provides another indication of the resources and attention Pyongyang is devoting to hypersonic weapons, but 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.
