CH-7 Stealth drone: revealed at China Airshow 2024

• The fifteenth iteration of the air show featured a dazzling array of some of the most advanced unmanned aerial vehicles.
• China plans to unveil a comprehensive array of advanced drones at the Zhuhai Air Show.
• The development of the CH-7 is indicative of China's ongoing endeavours to bolster its inventory.

China has recently captured international attention by unveiling a series of highly significant advancements in military technology, particularly in anticipation of the forthcoming Zhuhai Air Show, one of the most prominent aerospace exhibitions globally. Among the standout innovations is the much-anticipated J-35A stealth combat aircraft, which has sparked considerable intrigue, complemented by the introduction of an upgraded model of the CH-7 stealth drone. This drone has quickly gained attention through its striking images circulating across various media platforms and social networks, illustrating China's commitment to advancing its aerial capabilities.

The CH-7 is classified as a high-altitude, long-endurance unmanned combat aerial vehicle (UCAV). Developed by the state-owned China Aerospace Science and Technology Corporation (CASC), it first made its debut at the 2018 edition of the China Air Show to a curious audience. The CH-7 is engineered with sophisticated stealth technology, allowing it to infiltrate hostile airspace with remarkable efficiency. This drone is not only capable of conducting intelligence, surveillance, and reconnaissance (ISR) missions but is also designed to execute precise strikes while evading enemy detection, thereby enhancing its tactical utility in modern warfare.

On November 8, a series of captivating photographs and videos showcasing the CH-7 in an innovative configuration surfaced on various social media platforms. In these striking images, the drone is displayed in a vivid yellow colour scheme, positioned prominently on a runway that hints at the progression of its taxi testing phase. The anticipation surrounding its appearance at the upcoming Zhuhai Air Show is palpable, as this event serves as a significant platform for showcasing cutting-edge military technology, attracting both industry professionals and the public eager to witness the latest advancements.

At this stage, it remains uncertain whether the showcased CH-7 model is an advanced prototype or a pre-production variant. A report earlier this year from Global Times, a state-owned Chinese media outlet, indicated that the testing phase for the CH-7 had reached completion, with expectations that its final development stages would conclude within the current year.

Since its introduction in 2018, the CH-7 drone has undergone an extensive evolution, with its design continually refined to optimise its endurance and stealth capabilities. Significant modifications have been made, resulting in several iterations that reflect the ongoing enhancements based on rigorous testing and technological developments. Notably, a previous model of the CH-7 was exhibited at the 2022 Zhuhai Air Show, signalling the drone's evolution within the context of a rapidly advancing technological landscape.

Military analysts and observers have noted that the recently photographed CH-7 likely represents the culmination of its design process. This latest iteration is notably larger than the previous mock-ups exhibited at earlier air shows, showcasing a modern flying-wing configuration that improves aerodynamic efficiency and minimises radar detection, thus reinforcing its stealth capabilities.

While the Chinese government has not publicly disclosed the exact technical specifications of the CH-7, open-source intelligence suggests that this advanced drone measures approximately 10 meters in length, with a spacious wingspan extending to 26 meters. The aircraft is estimated to achieve a maximum take-off weight of 10,000 kilograms, a top speed of 926 kilometres per hour, and an impressive operational endurance of up to 15 hours, significantly enhancing its capability to conduct protracted missions in challenging environments.

Despite the limitations in independent verification of these specifications by sources such as EurAsian Times, it is apparent that the latest CH-7 represents a leap in dimensions and capabilities compared to its original mock-up, which was introduced five years ago. This progression highlights China’s unwavering dedication to technological advancement in military aviation.

Experts in military technology have remarked upon several impressive features integrated into the CH-7, including a newly conceived cranked kite wing, which enhances aerodynamic performance, along with updated wing flaps that offer increased control during manoeuvres. The incorporation of a flat exhaust system and sharper canted wingtips serve to further reduce its radar signature, enhancing its operational stealth. The CH-7 is powered by a single, unspecified turbofan engine and boasts an internal payload weapons bay designed for various munitions, underscoring its versatility in operational roles.

Shi Wen, the chief engineer overseeing the development of the CH series drone, shared insights in a 2022 interview with Global Times, highlighting that the CH-7 has a maximum take-off weight of 10 tons, enabling it to carry substantial missile loads. Furthermore, he emphasised the drone's stealth design, which diminishes its chances of detection by enemy radar systems, effectively reducing the engagement range of adversaries' anti-air defences. This critical feature significantly enhances its operational effectiveness in the diverse and information-driven combat scenarios characteristic of modern warfare.

Chinese experts further assert that the CH-7 is capable of operating at much higher altitudes than many of its competitors, allowing it to conduct prolonged surveillance of hostile targets. The drone is engineered for exceptional performance in both daytime and nighttime reconnaissance missions and is equipped to thrive in particularly hazardous environments where traditional aircraft might falter.

The introduction of the CH-7's final variant holds substantial significance, as it aligns with China's recent unveiling of the J-35A, marking a pivotal step in the country’s second venture into stealth aircraft production. Observers have drawn parallels between the J-35A and the U.S. F-35 Lightning II combat aircraft, suggesting the possibility of a derivative design. Similarly, the CH-7 has prompted comparisons to the classified U.S. RQ-180 UAV, reflecting a strategic push towards developing competitive aerial capabilities in the realm of unmanned aviation.

The development of the CH-7 is indicative of China's ongoing endeavours to bolster its inventory of long-range, low-observable drones capable of executing ISR and strike functions. This commitment to enhancing military capabilities has been a focal point of China's defence strategy, revealing an aggressive pursuit of technological superiority.

In addition, a CCTV report released in February unveiled the existence of another long-endurance stealth UAV, known as the SkyHawk. Furthermore, China is progressing with the development of the GJ-11 Sharp Sword, a UCAV designed to operate as a "loyal wingman" for the advanced J-20 stealth fighter jet, thereby enhancing complementary aerial capabilities.

China plans to unveil a comprehensive array of advanced drones at the Zhuhai Air Show, scheduled to occur from November 12 to November 17. As the largest biennial aerospace exhibition in the country, the event is poised to attract significant public interest, serving as an important showcase for both military and commercial aircraft alongside various other cutting-edge military technologies.

The fifteenth iteration of the air show featured a dazzling array of some of the most advanced unmanned aerial vehicles (UAVs) produced in China. This included an impressive lineup of combat drones developed by the People's Liberation Army, as well as a variety of previously revealed models from the CH series, together illustrating the latest advancements in China's robust military aviation capabilities.
