The vehicle has performed two flights, the first in 15 September 2002 and the second 16 September 2003. The first flight failed to place a 50 kg satellite into polar orbit due to a second stage malfunction. The second flight was also a failure, however Chinese officials declared some success citing the guidance systems, fairing separation and satellite-launcher separation as successful. The second launch sent the payload, PS-2 microsatellite (40 kg) into wrong orbit. The satellite completed barely one orbit before re-entering the atmosphere.
