China’s new long endurance solar-powered UAV will form an important component of its developing maritime intelligence system.

Not surprisingly, the authors of this analysis also see many maritime applications for the Rainbow UAV as well. Fisheries management is an obvious and important domain that could see employment of this platform. But the article also sees the Rainbow UAV as having potential contributions to make in the fight against smuggling, piracy and even in a notional counterterrorism mission. The analysis suggests the Rainbow UAV could help to “assist the customs and the coast guard agencies to undertake real time surveillance of both the near seas and also the economic exclusive zone (EEZ)” (协助海关或海警部门进行近海或专属经济区的实时监视). With respect to “protecting maritime rights,” the analysis points out some advantages over manned systems and it is also mentioned that the Rainbow UAV can play a useful role as a communications relay link to remote reef bases.

The article notes that the discussion topic regarding “whether the Rainbow UAV can actually play a role in the anti-carrier system” has been a “hot topic” of discussion in China (‘彩虹’太阳能无人机在反航母体系中到底能否发挥作用 . . . 引起了. . . 热烈讨论). It is noted that Beijing now fields a wide array of surveillance assets from radars to sonar arrays, but it is also suggested that each of these elements has certain weaknesses. To build the first-rate maritime surveillance system that China is said to require, the Rainbow UAV is described as an “excellent choice.” (非常好的一个选择). Stressing both the time urgency and also the low cost, the authors argue that the Rainbow UAV can rather quickly—and quite cheaply—become a critical component of the developing system.

It is observed by the Chinese authors that tracking ships at sea is substantially easier that finding much smaller targets that can be camouflaged or buried on land. Stating the obvious, the article notes that aircraft carriers are a large and also loud target, giving off all kinds of emissions that can be also detected by passive means. “As a target, (the aircraft carrier’s) special characteristics are extremely obvious.” (作为目标物来说, 各种特征都是非常明显的的) In such a role of detecting adversary aircraft carrier groups, the Rainbow UAV is said to have an “enormous deterrence value and can then secure victory against the enemy.” (对敌人造成巨大威慑效果 , 进而赢得胜利). And yet the piece is also not naïve about the challenges either, admitting that the current prototype does not yet actually have the requisite capabilities for such missions. Moreover, it states that complications, such as weather or a target cloaking its locations by operating without sensors and communications, could present the challenge of finding a “needle in the big ocean” (大海捞针). Thus, the task of locating the enemy’s carrier group is surmised to be “actually not so easy” (并不是那么容易). Indeed, new Chinese UAVs will work together in this mission with a comprehensive surveillance system that includes new satellites, long-range patrol aircraft of various types, a variety of undersea sensors, as well as Skywave radars that can see out to sea for thousands of miles. This list, moreover, does not include the likely employment of the world’s largest coast guard, fishing and also merchant fleets that may also be useful for tracking adversary ships.

A recent issue of Aerospace Knowledge (航空知识) ran with a large and dramatic fold out spread of an interesting moment in aviation and geopolitical history. The foldout shows a painting of PLA soldiers crawling over the wreckage of an American U-2 surveillance aircraft that had crashed in China during the early 1960s. That wreckage is familiar to any who have visited the military museum in Beijing. It has been asserted that one of the major strategic results of that particular ambitious U.S. surveillance program was to encourage the Chinese to create a first-rate air force and air defense system as national priorities. It seems likely that another result could well be that Beijing will vigorously pursue a global surveillance posture akin to the American posture it has studied closely for so many decades.
