China recently tested a Z-18A helicopter which can be used as an anti submarine warfare, military heavy lift and as a troop and VIP carrier.
According to China Military Online China recently tested it on the Tibetan plateau at an altitude of 8000 meters.
The report said that the Z-18A helicopter is meant to transport the AH-4 155 mm light artillery system developed by the China North Industries Corporation which weighs around 4 tons.
The Z-18A helicopter series developed by Changhe Aircraft Manufacturing Company is said to become the second type of helicopter for the army aviation troops of the Chinese People's Liberation Army (PLA) to conduct operations in high altitude. Currently, China uses 18 "Black Hawk" helicopters manufactured by Sikorsky.
The Z-18 series transport helicopters evolve from the AC-313 helicopters made by the Changhe Company. The AC-313 has a maximum takeoff weight of 13.8 tons. It can accommodate 27 passengers, with a payload of 5 tons.
