This article is about the rocket. For the submarine, see Chinese submarine Changzheng 1.

The Long March 1 (长征一号), also known as the Changzheng-1 (CZ-1),[3] was the first member of China's Long March rocket family.[4] 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.[5]

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.[6]
