   The new Chinese J-31 stealthy aircraft was developed by Shenyang Aircraft Corporation (SAC). Development of this aircraft started in around 2008. Some sources report that in 2007 China received blueprints and other classified information of the F-35 Joint Strike Fighter. This data was used to build the J-31. It is estimated that this stolen classified information saved China 25 years of research and development.

   The J-31 made its maiden flight in 2012. In the West it is considered as a fifth-generation multi-purpose medium fighter. However China considers it is a forth-generation warplane. Currently only little is known about this new Chinese aircraft.

   It seems that this new aircraft will reach production. Some sources report that China plans to produce about 1 000 of these stealthy fighters. Possibly this aircraft will be also proposed to export customers.

   The J-31 resembles a scaled-down version of American F-22 Raptor. This stealthy aircraft is smaller than the Chengdu J-20, which appeared in 2010. It is about the same size as the F-35 Joint Strike Fighter and has some of its features.

   Prototype of the J-31 is fitted with two Russian Klimov RD-93 engines. However engines on production aircraft might be different. These are likely to be domestic engines.

   The J-31 has two internal weapon bays. Each of them can carry two missiles. Also there are three hardpoints on each wing.

   It is speculated that the J-31 might be also used as a carrierborne multi-role fighter and operate from the new Chinese Liao Ning aircraft carrier. Currently the Chinese government pays enormous attention to development of advanced fighter jets.
