这是AG600飞机继2017年陆上首飞、2018年水上首飞之后的又一里程碑事件，也为下一步飞机进行海上科研试飞及飞机相关性能验证奠定了基础。
China's homegrown large amphibious aircraft AG600 successfully completed its maiden flight over the sea on Sunday in the coastal city of Qingdao, east China's Shandong Province, its developer has announced. The aircraft took off from the sea off Qingdao at 10:18 a.m. and completed the test flight after flying for about 31 minutes, said state-owned Aviation Industry Corporation of China (AVIC). Sunday's successful flight from the sea is a major breakthrough for the aircraft following its maiden flight over land in 2017 and first takeoff from a water reservoir in 2018, said AVIC.AG600 flying across the water during its maritime flight in Qingdao, Shandong Province, July 26, 2020. /CCTVAG600是中国为满足森林灭火和水上救援的需要，首次研制的大型特种用途民用飞机，是国家应急救援体系建设急需的重大航空装备。
