The Boeing was not just ugly, it failed to do both stovl and supersonic in one fighter, which was a requirement ‘ Due to the heavy delta wing design of the X-32, Boeing demonstrated STOVL and supersonic flight in separate configurations, with the STOVL configuration requiring that some parts be removed from the fighter. The company promised that their conventional tail design for production models would not require separate configurations. By contrast, the Lockheed Martin X-35 concept demonstrator aircraft were capable of transitioning between their STOVL and supersonic configurations in mid-flight.[4]
