DF-5
Development of the the DF-5 began in 1964. The goal was an ICBM capable of reaching the United States. Although deployed in very limited numbers as an ICBM, this rocket became the basis for an entire family of space launch vehicles and the foundation of the Chinese space program.

The missile was designed from the beginning to include China's first full inertial navigation guidance package. On January 4, 1966, Tsien proposed development of a countermeasures package for the DF-5 to evade American anti-ballistic missile systems. This was to included electronic jammers and spoofers and balloon decoys. American investigators would claim, beginning in the 1990's, that the CZ-5 incorporated Titan 2 missile technology. Flight tests began in 1971 but the missile did not enter service until 1981, following a series of two recoverable-warhead tests.

  • CZ China's first ICBM, the DF-5, first flew in 1971. It was a two-stage storable-propellant rocket in the same class as the American Titan, the Russian R-36, or the European Ariane. The DF-5 spawned a long series of Long March ("Chang Zheng") CZ-2, CZ-3, and CZ-4 launch vehicles. These used cryogenic engines for upper stages and liquid-propellant strap-on motors to create a family of 12 Long-March rocket configurations capable of placing up to 9,200 kg into orbit. In 2000 China began development of a new generation of expendable launch vehicles using non-toxic, high-performance propellants with supposedly lower operating costs. However these encountered development delays, and it seemed the reliable Long March series of rockets would continue in operational use for nearly fifty years before being replaced. More...
