Chinese orbital launch vehicle. The CZ-2 was originally designed for launch of the FSW-1 recoverable military reconnaissance satellite.

Development of the launcher was begun in 1970 by the Chinese Academy of Launch Vehicle Technology (CALT) under president Ren Xinmin. The DF-5 intercontinental ballistic missile was the starting point for the design. Four gimballed liquid rocket engines with a total ground thrust of 2746 kN (280 tonnes) powered the first stage at lift-off. Second stage propulsion consisted of one fixed main engine with a vacuum thrust of 716 kN (73 tonnes thrust) and four sets of swivelling vernier engines with a total thrust of 46 kN (4.7 tonnes thrust). The computerised guidance system used an inertial platform. The development team was led by Tu Shou'e.LEO Payload: 2,000 kg (4,400 lb) to a 200 km orbit at 52.00 degrees. Failures: 1. First Fail Date: 1974-11-05. Last Fail Date: 1974-11-05. Launch Price $: 20.000 million in 1994 dollars.

  • 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...
