For some reason I don't have that pic either. I thought I had all the pics. Having this on Jan 2006 means a big thing because it is a new prototype.
Plane apparently has bulge to accomodate the satlink on the spine already, by Jan 2006. Use of a different primer on different areas of the aircraft is quite interesting, as that may mean the material underneath the grey primer is not the same as the one used under the yellow primer. Yet this is in contrast to the other J-10s taken around 2006 which is still completely yellow.
Planes that are flying in this paint condition are usually prototypes. With those tanks and all, its going through a flight test with some pretty long flight times. Planes that are in primer condition in the ground may or may not be prototypes, as they may also be being carted to a seperate painting section.
Huii. ... never noticed the SAT-COM behind the canopy ! ... but could it be that this is not a completely new airframe but one of the later prototypes/pre-serials (from the 101x numbers), that was rebuilt to the latest standard as it already has that Mirage 2000 style camo.
For my opinion we already should speak of an improved J-10B for these late-production types with the new blade-antenna + GPS-COM !
