The first of the two YAV-8B prototypes flying with leading-edge extensions - slightly larger than the final form adopted for the AV-8B.
Photographed on the occasion of its roll-out at St Louis, this is the first of four full-scale development prototypes of the AV-8B. On this photograph, it lacks the leading-edge extensions that will be a standard feature.
