Sea Dragon-2 ROUV is the successor of Sea Dragon-1 ROUV, developed by the same designer and also funded by COMRA, the funding provider of Sea Dragon-1 ROUV. During the deployment of Sea Dragon-1 ROUV, valuable information is obtained based on the feedback, and this info became the base for upgrading Sea Dragon-1 ROUV, which eventually became Sea Dragon-2 ROUV. From April 29, 2008 thru May 17, 2008, Sea Dragon-2 ROUV successfully completed its final sea trials in South China Sea under the leadership and supervision of Professor Zhu Jimao, and subsequently entered Chinese service.
