    One of the two different series of military surveillance satellites launched under the YW designation, although YW 5 was in a lower orbit similar to the ZY-2 satellites, lower than previous YW satellites. The launch vehicle was announced as a CZ-4B, but appeared to be a CZ-4B with the CZ-4C's restartable YF-40A upper stage under the larger CZ-4C nose fairing.
