A promotional video for the Zhuhai Airshow 2024 displayed China's new rotor UAV BF500 with a tandem rotor configuration.
The overall layout of BF500 is very similar to that of the U.S.-made CH-47 Chinook transport helicopter, not only in the propulsion system but also in the airframe. However, the UAV is nowhere near the size of the CH-47.
For this reason, it can be assumed that BF500 is intended as a cargo UAV with better available volume and based on a well-proven layout.
China is among the countries actively working on larger cargo UAVs of different types, such as rotorcraft and fixed-wing ones. Some of the recent fixed-wing cargo UAV prototypes were stated to be capable of ranges above 1000 km and payloads in the tonnes range. Some of these designs are converted from manned cargo aircraft, while newer designs are entirely new designs with a better cargo bay volume ratio, as there is no crew compartment.
The U.S. is taking a different route as the Army and Marines are banging the door for improved logistics capability in a shorter timeframe. An important project on this matter is the MATRIX autonomy kit for UH-60 Black Hawk helicopters to allow for remote control.
Advantages like reduced human effort and the pilot not being onboard make unmanned cargo platforms capable of more sorties in the same timeframe with no risk to qualified personnel. These qualities are important, especially for the forces putting their boots on the ground and being involved in high-intensity scenarios.
