Three key technologies combine to provide efficient, highly maneuverable tailless fighters -- high throughput digital processing technologies, on integrated/adaptive flight control system, and innovative control effectors.

Tailless aircraft face unique technical challenges in the area of flight controls: (1) control effectors exhibit non-linearities; (2) typically significant aerodynamic interactions occur between the various control effectors; (3) effectors generate control moments about multiple axes, resulting in a highly coupled system; (4) factors 1 through 3 make control allocation a very important issue; (5) instabilities in multiple axes make control priorities (6) maximum vehicle efficiency is achieved by effectively using control redundancy, when it is available, to maximize lift and drag or minimize signature.
