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.
Critics have previously noted that the Chengdu J-20 is all but a mirror copy of Lockheed Martin's F-22, an air superiority aircraft that is no longer in production. According to a report by the Washington Times, an anonymous user recently posted new images of the J-20 on Chinese military websites showing two key technologies that have long been touted as unique features of US fighter aircraft.
One of the technologies that apparently originated in the United States was the Distributed Aperture System (DAS), which is supposed to be one of the F-35's most important sensors (the aircraft itself is often colloquially described as a flying computer). DAS has been billed by advocates as a revolutionary capability allowing a pilot to see exactly what's going on 360 degrees around the aircraft — all but eliminating blind spots.
If you've ever read a report saying that the F-35 helmet lets the pilot see through the bottom of the aircraft, that functionality is made possible by DAS, Defense News notes. If the latest images suggest anything, now the Chengdu J-20 has a comparable DAS functionality as well.
"The camera lens with a relatively large optical aperture in the nose comes with a reddish-purple plating/coasting," says the posting on the China-based Chaoji Da Benying website, as reported by the Washington Times. The post, which included four pictures of the J-20 with what looks like a fresh coat of paint, noted that "it very much resembles the F-35's AN/AAQ-3 7 DAS."
The F-35's DAS, however, has been one of the driving factors behind why the jet has a low availability rate to conduct missions, Breaking Defense reported in June 2018.
