China's indigenously developed Caihong-4 (CH-4) unmanned aerial vehicle has successfully completed a set of live-fire tests in January. This is the first multi-type ammunition live-fire test for CH-4, conducted with five types of ammunition including 50 kg cluster bomb, 50 kg terminal-sensitive projectile, 50 kg satellite-guided bomb, 100 kg laser-guided bomb and 100 kg satellite-guided glided bomb. 

Designed based on CH-3, CH-4 is a medium-altitude long-endurance (MALE)-class, strike-capable reconnaissance platform that has been developed by the China Academy of Aerospace Aerodynamics (CAAA). 8.5 m-long CH-4 has a maximum take-off weight of 1,330 kg and a wingspan of 18 metres.
