Our Bureau - : Aug 29, 2022 - : 7:36 pm

The Caihong-4 (CH-4) ‘Rainbow’ armed drone is slated to receive upgrades to further enhance its operational capabilities and will be introduced into the market in early 2023.

The CH-4 is slated to receive a new heavy-fuel piston engine. According to China Academy of Aerospace Aerodynamics, a subsidiary of China Aerospace Science and Technology Corp, (CASC), a prototype drone fitted with the new engine recently completed all the tests required to verify its autonomous takeoff and landing, load capacity, flight ceiling and radius, as well as other functions. CH-4s that are presently in active service are powered by gasoline engines, while the new version will run either on diesel or kerosene.

The CH-4 will gain greater operating endurance and payload capability as a result of the new engine. The CH-4 is China’s most successful drone export and has been sold to at least 10 countries and according to its manufacturer has accumulated over 20,000 flight hours.

The drone has a maximum take-off weight of 1.3 tonne and payload capability of 350 tonnes of weapons/sensors.
