China to increase maritime surveillance with UAVs

By J. Michael Cole  /  Staff reporter

As Beijing locks horns with a number of countries over the islands and waters of the East and South China Sea, China has launched a program to greatly increase its remote-sensing capabilities through the use of unmanned aerial vehicles (UAV), reports said yesterday.

The State Council last year approved a 10-year “national marine zoning” program to establish integrated, three dimensional, high-precision monitoring of China’s maritime areas. As part of China’s 12th five-year plan, which runs through to 2015, the State Oceanic Administration has been ordered to increase its remote-sensing capabilities through the acquisition and deployment of UAVs, pilot training and the construction of support infrastructure, Xinhua news agency reported.

In addition to increased surveillance of coastal waters, the UAVs are to also monitor waters under Chinese jurisdiction — including the Scarborough Shoal (Huangyan Island, 黃岩島), the Paracel Islannds (Xisha Islands, 西沙群島) and the Spratly (Nansha Islands, 南沙群島) archipelago in the South China Sea — over which China has engaged in territorial disputes with a number of neighboring states including Taiwan, Vietnam and the Philippines.

According to the report, the UAVs are also to be used to conduct surveillance near the Diaoyutai Islands (釣魚台) in the East China Sea — the object of an escalating dispute since Sept. 11 after the Japanese government announced the purchase of three of the islets comprising the potentially resource-rich archipelago. Taiwan, Japan and China all claim sovereignty over the islets.

Although China already uses space-based sensors to monitor its waters, UAVs provide much greater mobility and precision (down to 0.1m), and can loiter over a targeted area providing constant and real-time imaging. This is a major advantage over space orbiters, which, because of their altitude can only scan the same location every two or three days, thus minimizing the effective monitoring of fixed and moving targets.

‧ Planned increases to China’s remote-sensing capabilities are part of China’s 12th five-year plan.

‧ In addition to increased surveillance of coastal waters, unmanned drones are to monitor waters under Chinese jurisdiction — including the Scarborough Shoal, the Paracel Islands and the Spratly Archipelago in the South China Sea.

‧ Drones are superior to space orbiters because the latter can only scan the same location every two or three days given their orbit.


At present, China relies mostly on satellites and manned aircraft to conduct maritime surveillance.

Japanese media reported last month that the US had agreed to use some of its Northrop Grumman RQ-4 Global Hawk drones — deployed at Andersen Air Force Base on Guam since September 2010 — to conduct surveillance over parts of Japanese territory and near the Diaoyutais, known as the Senkakus in Japan.

In recent years the Chinese military as well as law enforcement agencies have acquired and developed a number of unmanned vehicles, including fixed-wing aircraft and helicopters. The People’s Liberation Army Navy, and civilian maritime safety agencies, have also worked to actively integrate ship-based UAVs to their operations.

In related news, images released by Xinhua on Saturday indicated that J-10B and Sukhoi Su-30 all-weather combat aircraft had been dispatched to augment forces operating in the East China Sea Fleet.

This development occurs as the East China Sea Fleet held a tri-service landing drill which involved land, navy and air forces that simulated a landing attack. Dozens of landing ships took part in the exercise, with forces breaking rival army blockades and transporting troops to a landing area.
