# National University of Defense Technology

The National University of Defense Technology (NUDT; 中国人民解放军国防科技大学) is a national public research university headquartered in Kaifu, Changsha, Hunan, China. It is affiliated with the Central Military Commission. The university is part of Project 211, Project 985, and the Double First-Class Construction. With the predecessor founded in 1953 as the People's Liberation Army Military Academy of Engineering (中国人民解放军军事工程学院) in Harbin, the institution was officially established in 1978 in Changsha, Hunan.
NUDT was instrumental in the development of the Tianhe-2 supercomputer. In 2017, the university incorporated five military colleges, which are the PLA College of International Relations, the PLA College of National Defense Information, the PLA Xi'an Telecommunication College, the PLA College of Electronic Engineering, and the PLA Science and Engineering University College of Meteorology and Oceanography.
Due to its military nature and lack of public information, NUDT has not been ranked or ranked accurately or adequately. Considered the No.1 military academy in China, NUDT has been consistently called the "Military Tsinghua" (Tsinghua being the highest ranked science and technology-focused university in China). In a 2016 Chinese ranking, NUDT was ranked as one of the only four "Seven Star" universities in China (others include Peking University, Tsinghua University, and the Chinese Academy of Science).

## History

On 18 March 1952, as part of the development of the first five-year plan, Acting-Chief-of-Staff Nie Rongzhen and Deputy-Chief-of-Staff Su Yu presented the "Report on the Establishment of the Military Engineering Academy" to the Chairman Mao Zedong and Central Military Commission. Mao officially approved the review on March 26, establishing the project as one of the 156 national projects started under the Central Committee of the Chinese Communist Party's 1st five-year plan.

### Harbin Military Academy of Engineering

On July 11, Chairman Mao Zedong appointed Grand General Chen Geng as the first dean and president. On August 22, the CMC established the Military Academy of Engineering Preparatory Committee, and established an office at No. 59 Gongjian Alley in Beijing on September 1. The preparatory committee composed of Grand General Chen Geng as Committee Chairman, Xu Lixing as Vice Chairman, Li Maozhi, Zhang Yan, Huang Jingwen, Hu Xiangjiu, Zhang Shuzu, Ren Xinmin, Shen Zhenggong, and Zhao Zili. On September 16, 1952, the CMC General Political Department approved the establishment of the Provisional Communist Party Committee within the Preparatory Committee with Grand General Chen Geng as the interim party secretary and consisting of Xu Lixing, Li Maozhi, Zhang Yan, Hu Xiangjiu, and Huang Jingwen. On November 24, the CMC granted final approval for the academy and issued to the entire army "instructions for the transfer of 300 teaching assistants and 1,000 cadets to the Military Engineering Academy." The same day, the preparatory committee submitted a preliminary plan for school building to the Central Military Committee.
On June 3, 1952, CCP Premier Zhou Enlai wrote to the Vice Chairman Nikolai Bulganin of the Council of Ministers of the Soviet Union asking for consultants and experts to help establish the new Military Academy of Engineering. On May 13, 1953, a Soviet advisory group arrived. After the establishment of the institute, more than 300 Soviet experts in various fields participated in the construction of the institute. This relation continued until the breakdown in Sino-Soviet relations in the 1960s. As part of the establishment, the Central Military Commission used volunteers from the 3rd Army Corps, the Second Advanced Infantry School of the Southwest Military Region and the Military Science Research Office of East China Military Region. Upon completion, the training of military science and technology talent was extended to all service branches.
On December 15, 1952, the Central Military Commission approved the establishment of the Military Academy of Engineering Construction Committee. On January 30, 1953, the CMC General Political Department approved the Communist Party Committee of the Academy of Military Engineering. On February 21, 1953, the Central Military Commission placed the Academy of Military Engineering under its direct leadership. On April 25, construction began. On May 15, 1953, Chairman Mao Zedong ordered a limit of 800 maximum graduating students per year. On August 26, 1953, Mao Zedong issued the instructions for the establishment of the Military Academy of Engineering and the first semester, and wrote the registration for it.
On 1 September 1953, the Military Academy of Engineering opened its doors, with the opening ceremony attended by the Deputy Chief-of-Staff Zhang Zongxun. Zhou Enlai, Zhu De, He Long, Liu Bocheng, Luo Ronghuan and others wrote inscriptions for the college. The academy consisted of 6 departments, 5 colleges, 22 junior colleges, and 24 undergraduate majors. The colleges were 1st Air Force Engineering, 2nd Artillery Engineering, 3rd Naval Engineering, 4rd Armored Force Engineering and 5th Corps of Engineers.
On 1 September 1955, the academy curricula was changed to five years. At the same time, the Ministry of Science and Education issued "Interim Regulations (Draft) for Postgraduate Classes" as part of the development of the academy's graduate program.
The university was founded as the premier military academy of China. It had five departments and one prep department at the time of its founding, including departments of The departments of Chemical Warfare and Nuclear Warfare were established later.
During the Cultural Revolution, the university was transitioned to the Committee of National Defense Science and Technology, and was renamed Harbin Academy of Engineering in 1966. In 1970, the main body of the university including its central administration and 4 departments moved to Changsha in South-Central China due to the possible war with the Soviet Union, and was renamed Changsha Institute of Technology. Other departments were converted to at least five independent national universities, or taken by other national universities or science research institute. The university's name was changed to People's Liberation Army National University of Defense Technology in 1978 after the Cultural Revolution was over.
In 2017, as part of the massive military reforms, the PLA Electronic Engineering Institute, PLA Institute of International Relations, PLA National Defense Information Institute, PLA Xi’an Institute of Communication and The Institute of Meteorology and Oceanography of the University of Science and Technology were consolidated under the NUDT.
In 2015, the United States Department of Commerce added NUDT to the Bureau of Industry and Security's Entity List.
