 Although the new version looked much like the original, it was larger overall and featured a new wing planform.In order to increase wing area, extra "winglettes" were added outside of the engine pods and the entire planform was re-shaped to be more of a classic delta wing.The wing inside the engine pods, about ⅔ of the overall span, was swept at about 45°, the smaller area outboard of the engine was more highly swept at about 60°.
