"Chinese version of X-47B" :fkidding:
It isn't a Chinese X47B, Badguy is getting ahead of himself.
It's more in the class of the initial X47A Pegasus or Boeng's X 45 or the Euro nEUROn. A tech demonstrator before technologies for a production variant are fully developed. It's in the same size and weight class of the aforementioned (though nEUROn, X45 and Lijian are all considerably larger and have higher thrust engines than the original X47A) and even has the same low cost engine exhaust nozzle solution as X47A:
Mind you not even X47B is a production aircraft. Its a platform for the development of autonomous carrier landing and take-off technology and the development of carrier UCAV handling procedures.
