As the following images show, the Chengdu J-20 Mighty Dragon flew the Jul. 2 test sortie with main weapon bay doors opened.
This was the first time China’s stealth fighter opened the bay that will house some of its weapons.
Noteworthy, the inside of the bay was blurred and the typical People’s Liberation Army Air Force “roundel” was Photoshopped on the ceiling of the weapon bay.
In order to preserve their stealthiness and keep the RCS (Radar Cross Section) as low as possible, radar-evading planes rely on weapons bay: bombs and missiles to be fired are kept inside the bays until it’s time to use them.
At the end of March the second prototype of the stealth aircraft was seen featuring a missile deployment device on the side weapons bay which extracts the selected air-to-air missile and then closes the door to keep the reduced RCS.
Actually, the roundels inside the weapons bay seem to be photoshopped in there together with a blur to hide the internal weapons carried…
So are all these leaked images about the Chinese stealth program really a gov pr work?
A clear picture of the weapon bay found at Secret Projects Forum. Seems to have mounts for 4 standard PL-12 AAMs, or later on up to 6 rumoured PL-12C AMMs with cropped or folding fins.
Its is the second picture to the top you can see part of missile that had been painted out using clone tool in Photoshop or like program
