At the end of 1959 were obtained first rocket (arrived in Beijing). March 24, 1960 2nd Engineering Department decided to develop its version of RCC and the serial production (machine-building plant in Hongda, now «Hongda Industrial Group»). The work was done under the control of the team engineer Peng Lisheng (Peng Lisheng). Technology jets and cruise missiles have a lot in common, which should facilitate the implementation of applets. Flight tests layout was scheduled for the second quarter of 1961, but this time in connection with the «adjustment of policy development of the state economy» (probably meant «Great Leap Forward» of Chairman Mao — «VP») have been thwarted.
Work resumed in 1963, they wore a «top-secret nature.» Had to spend thousands of tests before the missile was made for flight tests. In development were applied first Chinese computers.
At the end of 1964 was released the first batch of missiles. The tests were conducted in Gansu Province (on the border with Inner Mongolia). In the entire route trains with rockets and test equipment were taken stringent security measures and secrecy. RCC was launched from a ship simulator launcher (initial speed of 30 m / s, temperature of combustion gases more than 2,000 degrees Celsius). In 1965 he conducted two missile launch, which were regarded as successful. In November 1966, during the municipal trials were conducted 9 starts (8 successful). From this year RCC began to come into service of coastal missile parts PLA Navy.
