Shenyang J-31 Gyrfalcon
The Shenyang J-31 (F60), rumored to be nicknamed "Gyrfalcon" (鹘鹰), or Falcon Eagle, is a twin-engine, mid-size Fifth-generation jet fighter currently under development by Shenyang Aircraft Corporation. A photo of a model labeled F-60 was posted on the Internet in September 2011. In June 2012, photos and camera video clips about a heavily overwrapped possible F-60 prototype being road-transferred on a highway started to emerge on internet, though some suspect it of mere being a L-15 trainer aircraft. Pictures of a possibly fully assembled aircraft parking on an airfield emerged on September 15–16, 2012. The F-60 is reported to be the export version, where the J-31 would be the domestic Chinese version of the same fighter.
With the maiden test flight of the prototype No.31001 on October 31, 2012, China became the second nation after the 1991 Advanced Tactical Fighter fly off, to have field-tested two stealth fighter design
The J-31 made its maiden flight on Oct 31, 2012 It was accompanied by two J-11 fighters in a ten-minute test flight with its landing gear lowered. Prior to the flight, it conducted a high-speed taxiing and then became airborne.
The appearance of the J-31 may cause neighboring countries to consider again the purchase of the F-35.
A quarter sized model of the J-31 was shown at the China International Aviation & Aerospace Exhibition 2012, hinting at a desire to offer the aircraft for export, as an alternative for those countries that cannot purchase the F-35. AVIC confirmed at the exhibition that the aircraft was intended for export, after the failure of the CAC/PAC JF-17 Thunder to win export orders so far.
Because the aircraft is in development, these specifications are speculated based from the available images.
