First Chinese IRBM, a single stage missile with the objective of carrying a 1500 kg warhead to Japan. The starting point for the design were R-12 construction drawings and a single exemplar of the missile provided by the Soviet Union prior to the break with Moscow in 1960. Following protracted development the design was accepted by the Chinese military for service in 1970.

The first launch failure in 1962 led to a two year delay and a complete redesign.

DF-2 Chronology


1959 June 20 - . LV Family: DF-2; Kosmos 2. Launch Vehicle: DF-2.
  • Decision to withhold R-12 and nuclear warhead drawing package from China over Sidewinder affair - . Nation: China. Related Persons: Khrushchev; Tsien. Spacecraft: Project 581. The Soviet Central Committee advises China it will not provide prototype or drawings of atomic bombs as agreed previously. Khrushchev promised China that he would provide the drawing package for the R-12 IRBM as soon as testing was completed. However then came the affair of the Sidewinder. At the end of 1958 or early 1959 a complete missile fell into the hands of the Chinese. They promised to provide it to the Russians, but then dragged their feet. They were finally told in February 1959 that unless they provided the Sidewinder, they would not be given the R-12 package. The missile was finally delivered but it was found that the key crystal in the infrared homing sensor was missing. The Chinese had also been caught disassembling a P-15 cruise missile at a training facility in China. It had taken the Russian trainers two days to get it reassembled correctly. Therefore on June 20 1959 the decision was taken not to transfer the R-12 or the promised nuclear warhead design to China.

    The Soviets created a new design bureau to copy the Sidewinder. Fabrication of the crystal for the infrared sensor was the main obstacle. The initial production batches had a 99% rejection rate. A state commission was set up to get to the bottom of the problem, but couldn’t find a solution. The main problem seemed to be low-quality ore provided by the mines.


1962 March 21 - . Launch Site: Jiuquan. Launch Complex: Jiuquan LA3. LV Family: DF-2. Launch Vehicle: DF-2. FAILURE: Failure of guidance and engine mounting. Impacted after 69 seconds of flight.. Failed Stage: 1.
  • - . Nation: China. Agency: PRC. Apogee: 0 km ( mi). First DF-2 launch attempt. The rocket impacted the earth after only 69 seconds of flight. Fundamental design errors were discovered in calculating flexing of the rocket in flight, placement of the guidance system, and engine mounting. The missile was completely redesigned for reduced thrust.

1964 June 29 - . Launch Site: Jiuquan. Launch Complex: Jiuquan LA3. LV Family: DF-2. Launch Vehicle: DF-2.
  • - . Nation: China. Agency: PRC. Apogee: 200 km (120 mi). Summary: This followed a two-year complete redesign and test program following the first launch failure in 1962. The reduced-thrust missile had a range of 1050 km with a 1550 kg warhead, barely enough to reach Japan..

1964 July 9 - . Launch Site: Jiuquan. Launch Complex: Jiuquan LA3. LV Family: DF-2. Launch Vehicle: DF-2.
  • Test mission - . Nation: China. Agency: PRC. Apogee: 200 km (120 mi).
