China's largest and most powerful private carrier rocket is scheduled to make its maiden flight next year, according to its developer.

The ZQ 2 liquid-propellant, medium-lift rocket is now under development at LandSpace in Beijing, one of the leading private rocket makers in China, and several parts to be used on the rocket have been manufactured and delivered, according to a statement from LandSpace.

According to the company, the 49.5-meter ZQ 2 will have a diameter of 3.35 meters－the same as those of most of China's Long March-series rockets, and a liftoff weight of 216 metric tons. It will be propelled by LandSpace's TQ-12 methane rocket engine, the first of its kind in China.

Before LandSpace, only the United States' SpaceX and Blue Origin had begun development and testing of such a machine.

The Huzhou facility will be able to produce about 15 ZQ 2 rockets and 200 TQ-12 engines per year starting in 2022, according to Zhang.
