The model was jetisoned and it's useful concepts were incorporated into the design of the TIE Interceptor. Darth Vader's TIE Advanced x1 prototype was also equiped with a hyperdrive, a major exception to imperial laws. The TIE Interceptor is more manuverable, carries more fire power, and is much faster than the standard TIE Fighter. Its design and features came from Darth Vader's TIE Advanced x1 prototype. Mounted on every all four tips of it's wedge-shaped wings are laser cannons.
Interceptors also have strong deflector shields, one on the front and one on the back.
It was a three-winged ship, with one engine mounted on each wingtip. The Wild Karrde , which appears to be a dilapidated Corellian Action VI Transport , is Talon Karrde's smuggling ship. It measures the standard 125 meters in length, but it is really a highly-modified smuggling ship. It is equipped with combat-rated shields and three turbolasers, a sophisticated sensor package, and a stealth travel system. It has room for his crew as well as a kennel for his vornskrs.
