"We are endeavouring to get the airworthiness certification from the civil aviation authorities by 2021, and deliver it to the customers by 2022," Xinhua quoted Huang Lingcai, the plane's chief designer at state-owned Aviation Industry Corporation of China (AVIC), as saying.
China developed the AG600 as part of a drive to modernise its military, amid a more muscular approach to territorial disputes in places like the South China Sea that has rattled nerves in the Asia-Pacific region and the United States.
It made its maiden flight in China in December. Huang also said the aircraft would make more flights this year, including its first takeoff from water.
AVIC has spent about eight years developing the aircraft, which is roughly the size of a Boeing Co 737 and is designed to carry out marine rescues and battle forest fires. It has a range of up to 4,500 kms (2,800 miles) and is designed to be able to take off and land in two metre (six feet) waves.
In December, state media said that the aircraft had received 17 orders so far from Chinese government departments and Chinese companies.
