The CZ-2E added four liquid rocket booster strap-ons to the basic CZ-2 core to achieve a low earth orbit payload capability approaching the Russian Proton, US Titan, or European Ariane rockets. The Long March 2E had a maximum payload capability of 9,500 kg to low earth orbit.
The CZ-2E was based on the mature technology of previous versions of the Long March launch vehicles. Wang Uongzhi was the Chief Designer for the vehicle. With a solid Perigee Kick Motor (EPKM, built by Hexi Company, China), the CZ-2E could put 3,500 kg into a geosynchronous transfer orbit. In May 2001, it was announced that another upper stage, the ETS was being developed for the CZ-2E. This would be an adaptation of the CTS of the CZ-2C, consisting of a Spacecraft Adapter and an Orbital Maneuver System.
