New images circulating on Chinese social networks indicate that China may be testing a second demonstrator of a compound helicopter based on the coaxial rotor and rear propulsor architecture, a concept made famous by Sikorsky in the United States.

Unlike the model previously seen in 2025, which was very similar to the S-97 Raider, the new aircraft appears larger and closer to the SB>1 Defiant, suggesting deep modifications or even the development of a new variant.
The helicopter features a longer and more slender fuselage, a possible fairing over the rotor hub, and changes that indicate modifications to the propulsion system. Although the image quality does not allow for a detailed technical analysis, experts point to clear similarities with Sikorsky’s X2 technology, including coaxial counter-rotating main rotors and a propulsive rotor installed in the tail, a solution aimed at significant gains in speed and performance.
Observers of Chinese military aviation believe the project is part of a broader technological evaluation, similar to the American Future Vertical Lift program. At the same time, China has also unveiled a tiltrotor developed by another manufacturer, indicating that the country is testing multiple configurations to determine which architecture best meets its future operational needs.
This type of helicopter offers important advantages in military scenarios, such as greater range, higher speed, the ability to accelerate and decelerate quickly, and better maneuverability compared to conventional helicopters and tiltrotors. These characteristics allow for faster movement, reduced exposure to threats, and greater evasive capability, factors that are crucial in modern battlefield operations.
