CZ-1D Space Launch Vehicle

To satisfy the need for launching small satellites into LEO, the PRC developed the CZ-1D launch vehicle. The CZ-1D design consists of a 2-stage vehicle with the first stage burning UDMH and nitric acid whereas the second stage utilizes UDMH and nitrogen tetroxide. The payload capacity of the CZ-1D is 900 kg to LEO and 300 kg to a sun-synchronous orbit (References 159-161, 191-192).
