The Long March 1 (长征一号), also known as the Changzheng-1 (CZ-1), was the first member of China's
Long March rocket family. Like the U.S.'s and the Soviet Union's first rockets, it was based on a class of ballistic missiles, namely the
DF-4 class.
History
Development started in January 1965 as the Seventh Ministry of Machinery Industry issued a design task. The two stage liquid fueled
DF-4 was modified by adding a third stage in order to make it to the desired orbit. Long March 1's second flight launched China's first satellite
Dong Fang Hong 1 to space on 24 April 1970. The rocket was operational during 1970–1971.
Wang Xiji was the chief designer of the rocket.
