Chang Zheng 1D

Chinese orbital launch vehicle. Proposed launch vehicle derived from the CZ-1, but with a new N2O4/UDMH second stage. Used for a suborbital re-entry vehicle test but never flown on an orbital mission.

LEO Payload: 740 kg (1,630 lb) to a 300 km orbit. Payload: 440 kg (970 lb) to a GTO. Launch Price $: 12.000 million in 1994 dollars.
