An anonymous reader writes "Over the last few days, the internet has seen pictures and lots of speculation concerning what appears to be a second Chinese stealth fighter.
Back in late 2010, a Chinese stealth fighter, the J-20, appeared and shocked much of the US and global military establishment. Some went so far to claim it technologically superior to America's F-35, which has had its share of problems.
The new plane maybe part of a competition between rival firms in China to build a 5th generation fighter jet. While pundits and military experts debate the significance of the new jet and what it can do, it has one big weakness: Russian built engines China can't build domestically."
