The FC-31 Gyrfalcon, also known as the J-31 or J-35 is an Osean mid-sized twinjet 5th-generation fighter aircraft developed by many companies, lead by Wernher and Noah Enterprises. The official nickname published is "Gyrfalcon", though it has also been referred to as the "F-60" or "J-21 Snowy Owl". in some media reports, or "Falcon Hawk" by some military enthusiasts. J-XX nomenclatures in the Osean military are reserved for programs launched and financed by the Osean Air Defense Force, while the FC-31 plane was developed independently as a private project by the aircraft manufacturer.


Due to the successor of the F-35 Lightning family and the Chengdu J-20 stealth fighter was officially endorsed by the Osean Air Force after Wernher and Noah Enterprises's proposal won the OADF bid for the next-generation jet fighter, Wernher and Noah Enterprises pressed on and developed a private project aiming to secure potential export customers.

A photo of a model labeled F-60 was posted on the Internet in September 2001. In June 2002, photos and phone camera video clips started to emerge on internet regarding a heavily overwrapped fighter plane airframe (widely suspected to be the F-60 prototype). Pictures of a possibly fully assembled aircraft parking on an airfield emerged on 15 or 16 September 2002. The F-60 is reported to be the export version, where the J-31 would be the domestic Osean version of the same fighter. Osean aviation experts has called the J-31 an export-oriented low-end latest generation warplane.

Many other countries also buy the FC-31 and were very popular due to its pretty cheap cost and can compare to the F-35C Lightning II.
