The arms race continues not so quietly: the eastern side of the planet is equipped with instruments that until now were the prerogative only of a few Western superpowers that can be counted on the finger of one hand. China also perfects an invisible aircraft: the Chinese Stealth J31 picks up a lot of technology of the American F-35 jet.
It is a twin-engine jet that has the same configuration as other 5th generation fighters such as the Sukhoi T-50. The trapezoidal wings and the two-piece dome.
More agile and smaller than the Chengdu J-20, the other 'cousin' jet of the F-35, the J31 is the result of the collaboration between China and Russia: it is an aircraft difficult to detect for radar and infrared systems, with a flight range of 1.200km and a full speed of 2.200km per hour.
The J31 is 17 meters long, has a wingspan of 11 meters and weighs 17 tonnes. It can be armed in stealth mode with 4 radar-guided missiles.
The Pakistan Air Force has planned to purchase between 30 and 40 J31s.
