2005年6月4日,是中国航空史上一个值得纪念的日子。40年前,我国自行研制的强5原型机冒着绵绵细雨,在江西樟树空军基地腾空而起,成功地实现了首次飞行,成为迄今为止我国研制和生产的唯一一种强击机。从迫切需要到濒临夭折,从艰苦试制到首飞成功,从优化设计到首批生产,从改进改型到批量出口,强5飞机走过了一条艰辛坎坷 June 4, 2005 is a memorable day in the history of Chinese aviation. 40 years ago, China’s self-developed Strong 5 prototype took drizzle and leaped into the air at Lishu Air Force Base in Jiangxi. It successfully achieved its first flight and became the only attack aircraft developed and produced in China. From the urgent need to the near end, from the arduous trial to the first flight, from the optimization of the design to the first batch of production, from the improvement of the reform to the export of bulk, the strong 5 aircraft has gone through a difficult ups and downs.
