CASC CH-7

CH-7 is a long-range, low-observable unmanned combat aerial vehicle of Chinese origin, known as Cai Hong-7 (Rainbow 7). Developed by the China Aerospace Science and Technology Corporation (CASC), it is designed for high-altitude and multi-mission operations, employing a flying-wing architecture that integrates reconnaissance, surveillance and precision strike capabilities.

The development process dates back to its first public unveiling at Airshow China in 2018. Modifications have been made to the wingspan and control surfaces of the model. It has been reported that full-scale testing is nearing completion around 2024^【1】.

On 15 December 2025, the CH-7 successfully completed its maiden flight at an airfield in northwestern China. During this flight, basic flight characteristics and autonomous takeoff and landing performance were tested. Further flight tests are planned to validate advanced performance metrics and mission payload capabilities^【2】.

The aircraft adopts a flying-wing configuration, with a blended wing-body design that enhances aerodynamic efficiency and supports low observability. An aerodynamic profile has been developed to reduce radar signature through features such as dorsal engine air intakes and internal weapons bays. The design also bears resemblance to the ANKA-3 model produced by TUSAŞ^【3】.

Based on design parameters, the CH-7 has an approximate length of 10 metres, a wingspan of around 22 metres, and a maximum takeoff weight in the ten-ton class. Powered by a single turbofan engine, it can cruise at speeds of approximately Mach 0.5–0.75 and operate at altitudes of 12 to 15 kilometres. Its operational range can reach thousands of kilometres, with an endurance of approximately 15 hours in flight.

The CH-7’s mission payload may include anti-radar missiles, standoff precision strike weapons, and electro-optical/sensor suites. Internal weapons bays increase payload capacity while maintaining a low radar cross-section.

The CH-7 is classified as a stealth UCAV (Unmanned Combat Aerial Vehicle), combining high-altitude capability, durability and low observability among modern unmanned aerial systems.
