GAIC Harrier Hawk  Harrier Hawk (Yao-Ying or Yaoying, 鹞鹰) series UAVs are Chinese UAVs developed by Guizhou Aircraft Industry Corporation (GAIC), some of which have entered service with Chinese military. Harrier Hawk I is based on Guizhou Central, another UAV designed by GAIC. Harrier Hawk I and Guizhou Central UAVs both share the identical conventional layout with low wing configuration, as well as the retractable tricycle land gear system. However, the fuselage of Harrier Hawk I is different than that of Guizhou Central in that instead of having an extremely smooth shuttle shaped fuselage of Guizhou Central, the fuselage of Harrier Hawk I is shaped in the form of turtle deck cockpit.
