The Z-20 is the informal name of China’s medium-lift (9-10 tonnes) utility helicopter, similar to the Sikorsky UH-60 Black Hawk, developed independently by China. The official name of this helicopter will be announced when it is commissioned. In recent years, a large number of Z-10, Z-19 and other armed helicopters have joined the Chinese People’s Liberation Army, making up for China’s lack of reconnaissance and attack helicopters. However, China has been lacking a 10-ton general tactical helicopter to carry out assault transport, airlift and logistic support tasks. China acquired 24 US Black Hawk helicopters in the 1980s.
