CZ-4C


Chinese orbital launch vehicle. The CZ-4C, first flown in 2007, had an upgraded second-stage engine that could be restarted in space. The vehicle also had structural rings at the base of the first and second stages, an interstage weather cover,ejected at liftoff, and the larger payload shroud introduced on the CZ-4B. All of these indicated that the vehicle was designed to take larger payloads to higher, more precise orbits than the CZ-4B.

LEO Payload: 2,800 kg (6,100 lb). Payload: 2,800 kg (6,100 lb) to a 900 km SSO. Launch Price $: 35.000 million in 1999 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...
