CZ-3B(A)


Chinese orbital launch vehicle. In February 1999 the China Great Wall Company announced it was developing more powerful Long March rockets using larger-size liquid propellant strap-on motors. The Long March 3B(A) would be available in 2002.

The rocket would be launched from the Jiuquan Satellite Launch Center in the northwest part of China because the existing CZ-3B launch pad at the Xichang Satellite Launch Center was not able to handle such a large rocket.

LEO Payload: 13,000 kg (28,000 lb) to a 200 km orbit at 28.50 degrees. Payload: 6,000 kg (13,200 lb) to a GTO.

AKA: Long March 3B(E); Chang Zheng-3B(E).
Status: Design 1999.
Gross mass: 580,000 kg (1,270,000 lb).
Payload: 13,000 kg (28,000 lb).
Height: 62.00 m (203.00 ft).
Diameter: 3.35 m (10.99 ft).
Thrust: 8,910.00 kN (2,003,040 lbf).
Apogee: 200 km (120 mi).

  • 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...
