CZ-2F Space Launch Vehicles

In 1992, with the approval of the Central Committee of the Chinese Communist Party, China began the development of piloted space-travel technology. The CZ-2F represents a modest extension of the existing CZ-2E with a 2-stage core vehicle and four strap-on stages, all employing UDMH and nitrogen tetroxide. The CZ-2F was designed to support the Chinese piloted spaceflight effort, with an initial launch in Novmbers 1999.

In June 1999 images purporting to be those of a version of China's Long March booster capable of launching a piloted spacecraft were made public. While some "enhancement" may have taken place, there is evidently considerable basis in truth of these images of the Long March 2F.
