It's not much of an exaggeration to say that military observers in the United States have been mildly freaked out by the sudden appearance of China's Chengdu J-20 fighter aircraft -- an advanced fifth-generation stealth fighter comparable to America's F-22 Raptor.
The existence of the J-20 was only revealed in public for the first time on December 29, 2010, and now Aviation Week reports that the aircraft has just completed its first test flight:
It looks like the landing gear remained extended throughout the flight and that it may have been a rather modest outing, but we may get more data on that later. A J-10 served as the escort.
There will be much read into the fact the event happened while U.S. Defense Secretary Robert Gates was visiting China, but the event's timing may have more to do with weather aligning properly than geopolitics.
