中国自主研制的大型灭火和水上救援水陆两栖飞机“鲲龙”AG600，继完成陆上和水上首飞后，研制方中国航空工业集团有限公司（航空工业）宣布将陆续投产4架试飞机，加快适航取证进度。

航空工业发言人周国强透露，在现有首飞成果的基础上，研制团队将充分挖掘该机平台潜力，进行飞机结构、系统改进优化设计，同时围绕提高最大起飞重量、增加增压舱、完善灭火和救援任务系统配置等方面，开展改进设计及试验验证工作。

此外，在001架机在水上首飞的基础上，AG600将围绕改进设计试飞验证、失速特性、水动特性、包线扩展等性能验证开展科研试飞，同时结合研发试飞穿插进行试飞员机型改装培训及试飞员资质培训，12月底完成第二阶段研发试飞工作。
