The nose wing on the Viggen works very well at high angles of attack, making it a routine manouvre to land on runways as short as a flight deck of a carrier, using vortex lift and the powerful engine to maximum benefit. Also in turning flight it comes into its own, while flying at low Cls (= high speed) it is more of a hindrance than a boost. At supersonic speed, when the centre of lift is at roughly 50& mean chord, it would be better to have a swing-wing nose wing, that tucks away, like the Milan, an experimental Mirage III variant.
