1937年中日战争全面爆发后,侵华日本海军经常遭到中国空军的小规模空袭,疲于应付之际迫切需要发展一种高速和高爬升率的防空战斗机。该项目于1938年被定名为“雷电”。机身上安装有重型装甲,可与陆军的Ki61“飞燕”战斗机一样使用所谓“武士道精神”刺激下愚勇的撞击战术击落B29。 After the Sino-Japanese war broke out in 1937, the Japanese invaders invaded China were often subjected to small-scale air strikes by the Chinese Air Force and were struggling to cope with the urgent need to develop a high-speed and high-climb-rate air defense fighter aircraft. The project was named “Thunder and lightning” in 1938. The body is equipped with heavy armor, and the Army’s Ki61 “Chevron ” fighter using the so-called “Bushido Spirit ” to stimulate the foolish impact tactics to shoot down B29.
