On April 28, 1993, the Chinese Great Wall Industrial Corporation and Motorola signed a launch services contract for multiple launch of Iridium communications satellites using CZ-2C/SD launch vehicles. The main differences between the CZ-2C and the CZ-2C/SD were: a modified fairing with a diameter of 3.35m; a newly developed Smart Dispenser; improved second stage fuel and oxidizer tanks; and second stage engines with higher expansion ratio nozzles.

AKA: Chang Zheng-2C/SD;CZ-2C/CTS;CZ-2C/SD;Long March 2C. Status: Active. First Launch: 1997-09-01. Last Launch: 1999-06-11. Number: 7 . Payload: 2,800 kg (6,100 lb). Thrust: 2,960.00 kN (665,430 lbf). Gross mass: 213,000 kg (469,000 lb). Height: 40.40 m (132.50 ft). Diameter: 3.35 m (10.99 ft). Apogee: 1,000 km (600 mi).

The Smart Dispenser included a solid rocket kick motor for insertion of the Iridium satellites into a 780 km circular orbit. Each CZ-2C/SD had the capacity of delivering two Iridium system satellites. A successful CZ-2C/SD demonstration launch was conducted from Taiyuan on September 1, 1997. The first three deployment launches for the Iridium program were successfully conducted on December 8, 1997, March 26, 1998 and May 2, 1998. Another variant of the vehicle was announced in May 2001 when it was announced that the DoubleStar and KOMPSAT-2 satellites would be launched by a CZ-2C with a CTS upper stage. This was apparently a further development of the SD and was a three-axis stabilised upper stage consisting of a Spacecraft Adapter and an Orbital Maneuver System. It was capable of putting 1400 kg of payload into a 900 km sun-synchronous orbit.

LEO Payload: 2,800 kg (6,100 lb). Payload: 1,400 kg (3,000 lb) to a 780 km 86 deg orbit. Launch Price $: 25.000 million in 1999 dollars.
