It's J-20 Firefang... but double!
The extreme mobility of the J-20's advanced aerodynamic profile is fully expressed. The J-20 design also allows for some very unique flight characteristics and very responsive flight control.
The J-20 is capable of extreme short-distance takeoff, and maintains consistent high manueverability for both low and high altitude.
The aircraft is a bit hard to handle without a fly-by-wire system, but it is defintely manegable.
The large size allows it to fufill the bomber role whilst maintaining its manueverable profile.

Notes for pilots:
Apply negative trim for stable flight. Lift ratio is very high
Takeoff speed is 170 mph
CTRL 7 for parachutes
Only mount cruise missles onto darker colored pylons
CTRL 1 for volley fire
