An experimental, simple, yet elegant twin-seater, with a flight control system modified from Jundroo’s Pigpen.

THIS IS FICTIONAL

Story:
In an alternative timeline, the Soviets decided to ignore the deficit in the wings of the Su-47 and put it in service.

The USAF assumed that their communist counterparts had overcome the difficulties constructing forward-swept wings, and concluded that they needed a stealth dogfighter ASAP…

As a result, the YF-22 was ditched because it was “too conservative”, as engineers from Northrop Grumman developed a canard + forward-swept wing variant based off the early YF-23 concept.

With a smaller size and lower cost, this prototype was assigned the YF-21.5 (never in reality would they name something like that)
