The Sikorsky Black Hawk family is one of the most well-known helicopters of recent history. In its dozens of guises, it serves over 20 militaries worldwide. One of the lesser known operators is the People’s Republic of China. Initially purchased to be operated in the mountainous terrain of Tibet and Xinjiang, the Black Hawk eventually found itself as an aid relief helicopter in the 2008 and 2013 earthquakes in Sichuan and an inspiration for the design of the Harbin Z-20 helicopter.
From 1979 to 1989, the United States sold numerous weapons systems to China, most notably the S-70 (UH-60) helicopter, which in its various incarnations is best known as the Black Hawk. 24 of these iconic staples of American soldiering were exported to the People's Republic of China for a cool $140 million. After the U.S. stopped selling arms to China over the communist nation’s slaughter of unarmed student protestors, Sikorsky ceased technical support for the exported helos.

It is thought to be comparable to the US-made Sikorsky UH-60 Black Hawk helicopter, the civilian Sikorsky S-70C-2 variant of which has been used by the People's Liberation Army since 1984.
Some sources suggest that the Z-20 is a copy of the Black Hawk because the Peoples Liberation Army Air force had bought 24 Sikorsky S-70-C2 which the Blackhawk is based on and link the design to the Black Hawk that was abandoned by US special forces in Pakistan during the operation to kill Osama bin Laden on 1 May 2011.[9] The sources say that Pakistan allowed Chinese officials to examine the Black Hawk wreckage. However, Aviation Week also points out that although some aspects of the design do appear similar, such as the tail wheel arrangement, there are also marked differences. For example, the Chinese Z-20 has a five blade rotor compared with the Black Hawks' four blades. Blackhawk helicopter design is around 40 years old, so a lot of information is available and China may have decided is better improving an existing known design that fits PLA operational requirements than assuming development risks. China has also used existing designs with its Z-8 and Z-9 helicopters.
While the Z-20 bears a strong resemblance to the S-70/UH-60 Black Hawk series, there are several key differences including a five-bladed main rotor and more angular tail-to-fuselage joint frame, giving it greater lift, cabin capacity, and endurance than the Black Hawk, as well as a fly-by-wire design. It also has fairings installed aft of the engine exhausts and on the tail spine, which are likely housings for satellite communications or the BeiDou satellite navigation system. The Z-20 is believed to be powered by the domestic WZ-10 turboshaft engine providing 1,600 kW (about 2,145 shp), compared to the latest GE T700-701D engine that produces 1,500 kW (about 2,011 shp). Having a less powerful engine than the UH-60 is offset by using new technologies that reduce weight and improve lift. These features enable it to conduct operations at altitudes up to 4,000 m (13,200 ft). It is not clear how much damage in combat can the helicopter tolerate or how will the helicopter perform in real operations when compared with UH-60. Z-20 has been given the nickname "Copyhawk" by some western analysts.
