As a rule one must be careful when using satellite photos to base intelligence on. The US, Russia, The PRC,UK, UK, Germany, Japan, France, and a number of other countries are all well capable of timing and mapping the orbit of spy satellites that pass overhead and the ground crews are often notified to clear the tarmac of any special projects in advance of such.
There are stories from the US constant peg program that the pilots and air crews would often prank Russian photo analyst by laying down objects on the roof of hangers spelling out various Russian curses or placing the nose of a aircraft out one side of a hanger and the tail of another out the back in perfect alignment so it appeared to be over a hundred foot long jet.
But along with the jokes the ground crews were taking steps to ensure that the F117 and USAF Migs were not visible from space.
One must assume the same thing here.
If that mystery object is there its there by design. Either the PLAAF is decoying with a mock up, or is announcing its existence.
Samurai pointed out the bent nose on another fighter aircraft. That could be a jet with its nose cone open being repaired a visual distortion or evidence that its not a real jet but a decoy.
In the First Gulf war and WW2 the US used inflatable decoys and jets made from tents to fool enemy intelligence. Its cheap and readily available tech. Seeing is not always truth.
