The new North Korean Saebyeol-4 strategic reconnaissance drone is using elements of the Chinese Chengdu J-7 fighter jet.

South Korean aviation columnist Minseok (James) Kim announced this on his X (ex-Twitter) page.

The DPRK state media recently released a video of the drone’s inspection by the country’s leader, Kim Jong-un, which allowed them to obtain detailed images of the drone in satisfactory quality.

The observer drew attention to the landing gear, which was withdrawn from the Chinese J-7 fighter jet. The landing gear layout did not change; however, the wheels of the main landing gear were reoriented from the inner to the outer position. At the same time, the front landing gear has not undergone any changes.

Accordingly, this may indicate that the drone was designed using off-the-shelf solutions, some of which may have been changed during the development process.

One can only assume which elements in the Saebyeol-4 were borrowed from other aircraft; the use of J-7 elements suggests that other components and assemblies of this fighter jet could have been used.

In July 2023, Militarnyi reported on the first demonstration of this drone.

Saebyeol-4 visually resembles the American RQ-4 Global Hawk strategic reconnaissance drone and, more specifically, its Rangehawk variant.

The exact specifications of the North Korean replica are unknown, but Minseok (James) Kim suggests that its takeoff weight is limited to 9 tons.

He made this assumption based on the technical characteristics of the J-7 landing gear, which is designed for aircraft weighing up to 9.1 tons.

It is safe to say that the North Korean Saebyeol-4 is inferior in its characteristics to the American RQ-4 Global Hawk because the DPRK has limited access to modern mil-spec technologies.

Therefore, the UAVs are most likely to use North Korean and Chinese electronics.
