Huang Xuhua
[7] After the Sino-Soviet split, Marshal Nie Rongzhen proposed that China develop its own nuclear submarines to break the duopoly of the United States and the Soviet Union, and Mao Zedong accepted the suggestion.In 1958, Huang was among the 29 people selected to develop the program, meant to bolster China's nuclear deterrence against the US and the USSR.Huang and his colleagues had very primitive resources, using abacuses to do calculations and gathering information from foreign newspapers.[3] In the late 1960s, Huang, together with scientist Qian Lingxi, was attacked for his "reactionary" background and sent to perform hard labour in the countryside, where he spent two years raising pigs.[10] In 1983, Huang Xuhua succeeded Peng as the 2nd chief designer and continued working on the nuclear submarine project.
