DFH-14

 1984-008A

---

The first Chinese experimental comsat was launched in Jan 1984. The third stage of the Chang Zheng 3 rocket failed to restart, leaving the satellite in a low orbit, but a successful test of the apogee motor and stationkeeping propulsion system was carried out. The satellite was referred to as Shiyan Weixing (Experimental Satellite) compared to the later STTW name, implying that this satellite may not have carried an actual communications payload.
