DAS.

This is coolbert:

 Stolen?

Also understand fully well not x-ray as that word x-ray normally, commonly and generally defined.

Thanks to the Russian media controlled [?] Internet outlet Sputnik:

"Chinese Jet Shows X-Ray Vision System Only Seen on US Jets"

"After months of complaints by the US administration that China is stealing intellectual property from companies in the United States, a picture of a Chinese fighter jet has been publicized on social media featuring key technology systems developed for the American F-35."

CHINESE STEALTH FIGHTER PLANE NOW EQUIPPED WITH TECHNOLOGY AND SYSTEMS THOUGHT TO BE ITEMS AS STRICTLY ONLY FOUND ON THE AMERICAN F-35 LIGHTNING?

F-35 systems mimicked to include:

* Distributed Aperture System (DAS). Again, x-rays.

* UWARS - "Universal Water Activated Release System- is a life-preserving system . . . The UWARS is attached to a buckle or harness that, when submerged in water, releases a harness and thus prevents drowning."

Stolen? Technology as obtained by espionage and then copied?
