A photo of a model labeled F-60 was posted on the Internet in September 2011. In June 2012, photos and camera video clips started to emerge on internet about a heavily overwrapped possible F-60 prototype being road-transferred on a highway, earning the nickname "the zongzi plane" (粽子机) among Chinese netizens, though some suspect it of merely being an L-15 trainer aircraft. Pictures of a possibly fully assembled aircraft parking on an airfield emerged on 15 or 16 September 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.
Chinese aviation expert Xu Yongling has called the J-31 an export-oriented low-end latest generation warplane.
The prototype conducted a high-speed taxiing test and briefly became airborne. On 31 October 2012, prototype No. 31001 conducted the model's maiden flight
It was accompanied by two J-11 fighters in a ten-minute test flight with its landing gear lowered.
With the maiden test flight of the prototype No.31001 on 30 October 2012, China became the second nation after the 1991 Advanced Tactical Fighter fly off, to have two stealth fighter designs in field-testing at the same time. The aircraft has continued a limited test program, with footage emerging of further flights which took place in February 2013

The Shenyang FC-31, also known as the J-31 or Gyrfalcon (Simplified Chinese: 鹘鹰) is a twin-engine, mid-size fifth-generation jet fighter currently under development by Shenyang Aircraft Corporation. It has also been referred to as the "F-60" or "J-21 Snowy Owl" (Simplified Chinese: 雪鸮) in some media reports, or "Falcon Hawk" by some military enthusiasts. J-xx nomenclatures in the Chinese military are reserved to programs launched and financed by the army, while this plane was developed by a state-owned company.

The J-31 is speculated to use stealth coatings instead of "baked in" fiber-mat stealth. Officials from AVIC claim the aircraft to be stealthy against L-band and Ku-band radars, and would be low-observable against a number of multi-spectrum sensors. The engine nozzles are apparently being redesigned to reduce radar and infrared signatures
