The first survey mission of the two ships was during May 1980. After being used for tracking of the launches of indigenously developed communications satellites, Yuanwang 1 and Yuanwang 2 underwent overhauls in 1986, so they could be used for supporting international satellite launches by the PRC.

Two further ships of the class have been built. First was Yuanwang 3, commissioned on 20 October 1995. The Yuanwang 4 tracking ship was constructed by China State Shipbuilding Corporation
