Fifth-Generation fighters such as the F-22 and F-35 favor chine-shaped forebodies which help reduce their Radar Cross-Section. The chine produces strong forebody vortices, which interact with the wing vortices. However, in certain conditions the interaction can produce asymmetric vortex breakdown, non-linear moments and roll departure. Future fighter aircraft will have this issue compounded as, to further reduce their RCS, future-generation fighter aircraft are projected to be tailless, sacrificing lateral control authority.
