Chang Zheng 2C
Part of CZ Family
CZ-2C launch
CZ-2C launch
Chinese orbital launch vehicle. The CZ-2C was the definitive low earth orbit launch vehicle derived from DF-5 ICBM. It became the basis for an entire family of subsequent Long March vehicles. Many adaptive modifications were made to the configuration of the CZ-2A to handle a variety of new satellites and upper stages. The CZ-2C had improved technical performance and payload capacity compared to the CZ-2A, with later versions having a payload capability of 2,800 kg into a 200 km circular orbit.

AKA: Chang Zheng-2C;CZ-2C;Long March 2C. Status: Active. First Launch: 1975-11-26. Last Launch: 2014-11-14. Number: 39 . Payload: 2,500 kg (5,500 lb). Thrust: 2,960.00 kN (665,430 lbf). Gross mass: 192,000 kg (423,000 lb). Height: 35.15 m (115.32 ft). Diameter: 3.35 m (10.99 ft). Apogee: 200 km (120 mi).

The CZ-2C could be launched from either the Jiuquan or Taiyuan launch sites. After its first FSW reconnaissance satellite mission on 9 September 1982 the CZ-2C launch vehicle successfully orbited six applications and two new recoverable satellites into space. On October 6, 1992, the Swedish Freja satellite was successfully launched as a co-passenger on the CZ-2C's thirteenth flight.

LEO Payload: 2,500 kg (5,500 lb) to a 200 km orbit at 52.00 degrees. Payload: 2,200 kg (4,800 lb) to a 200 km polar orbit. Launch Price $: 25.000 million in 1999 dollars.
