"The TYE-wing was one of the composite starfighter designs known as "uglies." TYE-wings combined the ball cockpit and wing braces of the TIE Fighter with the engine nacelles from the Y-wing. They were armed with two TIE fighter laser cannons, usually had a functional TIE sensor package, and had fair maneuverability. Unfortunately, they had no shields, no hyperdrive, and although they were faster than many uglies, they were quite slow compared to most mass-produced fighters."
