Discovery (Fa-xian, 发现 in Chinese) remotely operated underwater vehicle (ROUV) is a type of very little known unmanned underwater vehicle (UUV) originally built in Great Britain by British firm Specialist Machine Development (SMD) Limited for the People's Republic of China (PRC).^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8] and the British firm was later purchased by CSR Corporation Limited in April 2015.^[9]

Equipment

In order to complete its assigned missions, Discovery ROUV is equipped with seven underwater cameras, two high definition cameras, underwater positioning system, one Titan 4 and one Atlas manipulators,^[2]^[6] each is capable of handling objects weighing up to 120 kg,^[2] and when used together, objects weighing up to 300 kg can be handled.^[6] In addition, there are more than thirty different kinds of scientific instruments and equipment indigenously developed in China for the ROUV after it entered service.^[7]

Specification

Length: 3 meter
Width: 1.7 meter
Height: 2 meter
Payload: 300 kg^[2]
Maximum operating depth: 6000 meter

Upgrade

Merely less than half a decade after entering service, Discovery ROV went through an upgrade that lasted more than half a year in China, from end of October 2018 thru April 2019.^[7] It's reported that during this maintenance/upgrade, by incorporating more advanced technologies, the maximum operating depth is increased by a third, to the original 4,500 meters to 6,000 meter after Discovery ROV returned to service.^[3]^[4] The mothership of Discovery ROUV has been Chinese research ship Science (Ke-Xue, 科学)^[1]^[2]^[3]^[5]^[6]^[7]^[8] since the ROUV first entered service in 2014.^[1]^[2]^[3]^[5]
