Shenyang J-31

The Shenyang J-31 (or "FC-31 fifth Generation Multi-Purpose Medium Fighter") also known as the "Gyrfalcon" (鹘鹰), or "Falcon Hawk" by some military enthusiasts, is a twin-engine, mid-size fifth-generation jet fighter currently under development by Shenyang Aircraft Corporation. The fighter has also been referred to as the "F-60" or "J-21 Snowy Owl" (雪鸮) in some media reports. Its official name is Shenyang FC-31; 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.

In January 2019, the Chinese government announced that the J-31 would be developed as a carrier based multirole fighter that would be deployed from the PLAN's CATOBAR carriers.
