North Korean leader Kim Jong Un presided over a major exhibition of uncrewed aerial vehicles (UAVs) on Thursday. A mockup of an apparent new large stealth drone was displayed prominently alongside an increasingly diverse collection of reconnaissance drones, armed UAVs, loitering munitions, and small attack drones. While there is no evidence that North Korea is capable of getting a stealthy flying-wing drone flying, let alone operating as a operationally relevant low-observable platform, there are no doubts that the country has an increasingly impressive uncrewed aircraft arsenal, with the smaller, lower-end types being of greatest importance.

As for the “stealth drone,” photographs released by North Korean state media show a mockup of a tailless flying-wing design. In terms of appearance, there are clear parallels with advanced uncrewed combat aerial vehicles (UCAVs) developed by the United States, China, and Russia.

However, huge questions remain as to what degree the mockup is part of a realistic program. We have no details of the program’s development status and planned capabilities. It is highly questionable if Pyongyang is able to produce a functional prototype. Even if it can get it into the air, there is no evidence that it possesses the capabilities to master meaningful stealth technologies, let alone the command-and-control functions and other elements needed for it to operate in a tactically relevant manner.

The exhibition, titled Unmanned Aeronautical Technology Development-2026, was held on Thursday, with images published by the ruling Workers’ Party newspaper Rodong Sinmun today. Kim called for the country to achieve “absolute superiority” in drone technology and announced unspecified measures to accelerate the development of uncrewed aviation systems and military artificial intelligence.

An Ambitious New Flying-Wing Design

The mockup of the new aircraft was positioned prominently in the exhibition hall, suggesting that Pyongyang considers it at least indicative of its broader ambitions.

Based on the available photographs, Hong Min, a senior research fellow at the Korea Institute for National Unification, interviewed by NK News, estimated the wingspan at roughly 56 to 66 feet and its height at around 10 to 11.5 feet. Standout features include a dorsal air intake, a relatively large center fuselage section integrated into the flying wing, and retractable tricycle landing gear.

In terms of general arrangement, there are similarities to Northrop Grumman’s X-47B, the U.S. Navy’s experimental carrier-based UCAV. There are also visual similarities with China’s GJ-11 Sharp Sword and Russia’s S-70 Okhotnik, two other large flying-wing UCAV designs.

At this point, North Korea has not provided any technical information about the aircraft’s propulsion system, payload, intended mission, or flight performance.

Critically, while the external shape is consistent with a stealthy UCAV, a flying-wing configuration on its own is only one part of a far more complex puzzle in achieving a genuinely low radar signature. Other factors include the engine inlet and exhaust arrangements, radar-absorbing materials, surface treatments, manufacturing tolerances, and the alignment of individual edges and surfaces, low probability of intercept communications and much more.

The Iranian RQ-170 Precedent

Overall, there are many good reasons to be extremely cautious about North Korea’s apparent ambitions in this area.

Iran is another country that has displayed a drone that resembles an advanced Western stealth platform, without actually reproducing its capabilities. It has, however, gotten a UCAV-lookalike into the air.

After recovering a U.S. RQ-170 Sentinel reconnaissance drone that came down inside Iranian territory in 2011, Tehran announced that it had successfully reverse-engineered the aircraft. In 2014, Iranian authorities displayed what they presented as a domestically produced copy of the American drone, claiming that it would soon undertake a test flight.

Outside observers questioned whether the displayed aircraft was anything more than a non-functional replica, noting apparent shortcomings in its construction and the use of components inconsistent with a sophisticated operational aircraft.

Iran subsequently presented a family of aircraft derived from the RQ-170 concept, including the Shahed-171 Simorgh and the smaller Shahed-191. Iran has demonstrated flying examples of these designs, but they fall far short of replicating the RQ-170’s actual low-observable qualities, let alone its sensors and avionics.

In the case of Pyongyang, however, the possibility of Russian assistance is at least worth considering.

North Korea’s burgeoning military relationship with Moscow, including the deployment of North Korean troops to support Russia’s war in Ukraine, could provide a chance for the exchange of technical knowledge and operational experience from Moscow. Russia has developed and flown the S-70 Okhotnik UCAV, exposing it to some operational trials in Ukraine, and could have passed related information on to Pyongyang.

In particular, North Korea would welcome Russian assistance in developing and manufacturing propulsion, flight control, sensor, and materials technologies.

However, there is so far no proof of technology transfer from Russia. Even if it were to be provided, it is far from clear that this would suffice to get a true UCAV into the air anytime soon, although an Iran-style knockoff with far reduced capabilities cannot be ruled out entirely. It’s also worth noting that Russia’s own UCAV program has been anything but a smooth and rapid advancement to an operational state.

Overall, the new flying-wing concept does not represent a realistic technological undertaking — at least for now. Very few countries have managed to develop and fly drones in this class, and fewer still have been able to field them operationally.

North Korea’s Drone Development Effort

The flying-wing aircraft was only one part of a much larger display. More than 30 types of UAVs reportedly appeared at the exhibition, reflecting North Korea’s efforts to diversify its uncrewed aviation capabilities.

Some of these designs had been seen before, including the Saetbyol-4 and Saetbyol-9. These were first displayed in 2023 and are, in terms of appearance, clones of the U.S. RQ-4 Global Hawk and MQ-9 Reaper, respectively.

Imagery released of the Saetbyol-9 showed it carrying — and firing — several types of air-to-ground weapons. These include a Hellfire-like laser-guided missile, along with smaller rockets and other possible guided munitions.

Other exhibits included loitering munitions resembling Israel’s Harop and Russia’s Lancet, as well as smaller drones with configurations similar to the U.S.-made Switchblade family.

Hundreds of small quadcopter drones were also displayed on storage racks. Some appeared to carry cylindrical containers associated with fiber-optic control systems, a technology that has become increasingly prominent in the Russia-Ukraine war. Unlike conventional radio-controlled drones, fiber-optic systems are largely immune to conventional radio-frequency jamming of their control links. These drones would be a major feature in a cross-DMZ conflict.

North Korean interest in artificial intelligence was another recurring theme. Kim called for the development of increasingly intelligent uncrewed weapons, although there is no indication of how advanced the country’s existing autonomous navigation, target recognition, or engagement systems actually are.

The exhibition was accompanied by live-fire demonstrations involving UAVs, cruise missiles, and multiple rocket launchers. North Korean state media claimed that missiles launched from drones and other systems struck an island target “with 100 percent accuracy.”

From Ambition To Operational Capabilities

North Korea’s rapidly expanding interest in drones should also be seen against the shortcomings of its aging crewed combat aviation fleet. Relatively inexpensive UAVs offer opportunities for reconnaissance and attacks against military infrastructure without exposing pilots to enemy air defenses. At the same time, Pyongyang has failed to introduce new crewed combat aircraft to modernize its air force, the capabilities of which are thoroughly outmatched by those of South Korea.

The war in Ukraine (as well as lessons from conflicts in the Middle East) also provides Pyongyang with an opportunity to study the use of drones on a large scale. North Korean troops deployed to Russia will have gained first-hand experience of drone warfare, including the integration of reconnaissance UAVs, FPV attack drones, and electronic warfare systems.

That experience could help accelerate the development of North Korea’s own uncrewed platforms, particularly relatively simple systems that can be produced in large quantities.

An attack drone in the Shahed/Geran class, for example, could be produced relatively easily in very large numbers (and that is likely already happening to some degree) and could saturate South Korean air defenses, which are generally tailored to address more conventional threats. North Korea doesn’t need the long range that the Shahed/Geran typically provides, since many of its primary targets are much closer. The shorter distances involved could permit a greater proportion of a drone’s weight to be allocated to its warhead, depending on the design. Alternatively, a drone with the roughly 1,000-mile reach of the Shahed/Geran could fly a very complex route to reach targets in the South, including approaching via the coast. At the very least, expanding North Korean efforts in this area could tilt the balance of power on the peninsula, providing Seoul with a major interdiction problem and forcing the development of new countermeasures, such as directed-energy weapons and cheap interceptors.

The possibility of Russian assistance via its own Geran development effort is likely bringing enhanced technologies within reach of North Korea. Indeed, that kind of expertise is already being gained by tens of thousands of North Korean workers who have been sent to Russia as additional labor for its drone-production efforts.

And once again, it’s these one-way attack munitions and smaller drones that can be mass-produced and rapidly iterated upon that pose a real threat to South Korea. It is likely that North Korea will continue to ramp-up its investment in these systems, building them in very large tranches in order to create an asymmetric advantage — one that has proven challenging to counter in real conflicts around the globe. At the same time, they will also continue to build high-tech-looking clones of far more advanced systems which will have little tactical or strategic impact but work well for propaganda purposes.
