| Design basis reported by article | The Chinese 8A4 class ROUV is a remotely operated underwater vehicle (ROUV) used to perform various underwater tasks, ranging from oil platform service to salvage and rescue missions. The 8A4 is a member of a series of related ROUVs developed by the Shenyang Institute of Automation (SIA) in the People's Republic of China (PRC). The predecessor to the 8A4 was the RECON-IV, an improved version of the American RECON-III. The 8A4 itself is an upgraded version of the American AMETEK 2006, and the 7B8 is an improved version of the 8A4.[source] | — |
