The CAIC Z-10 (Chinese: 直-10, "helicopter-10"), also called WZ-10 (Chinese: 武直-10, "armed helicopter-10"), is a Chinese medium attack helicopter developed for the People's Liberation Army Ground Force. It is designed primarily for anti-tank warfare missions but has secondary air-to-air combat capability as well. Initiated by chief designer Wu Ximing, the project had early Russian involvement with Kamov Design Bureau of Russia under a contract with the Chinese government, but the collaboration was abruptly stopped due to fundamental design philosophy disagreements. The Chinese designers and their customer, the PLA General Armaments Department, preferred a lighter-weight, more agile airframe with less emphasis on armor. The helicopter was further developed by Changhe Aircraft Industries Corporation (CAIC) and locally manufactured.
