A former U.K. Ministry of Defense professor says China's plan to launch eight more ocean-monitoring satellites”two of them with radar capabilities”is more likely for military purposes. China already has three maritime satellites in orbit. Professor John Walker, Nottingham Trent University, said adding eight more was “a very significant investment just to monitor water.”
“I would expect the real value of these satellites to be more military and intelligence gathering,” he said.
Professor Walker has previously worked at the Royal Signals and Radar Establishment, the U.K.'s former scientific research body within the Ministry of Defense. Currently, China’s sea-monitoring system covers about 300,000 square kilometers (115,000 square miles) of ocean around the country, according to the country’s State Oceanic Administration.
National Satellite Ocean Application Service Director Jiang Xingwei told the China Daily newspaper the new satellites had already been approved by the National Development and Reform Commission. According to the report, four will observe the color of the sea, two will monitor currents and two will be radar satellites.
