Darth Vader's TIE Fighter is the prototype that was used as the basis for all the terrifyingly effective TIE Fighters and Interceptors that would be developed for future battles. The TIE Fighter has proved itself in battle, as it is capable of withstanding many direct hits. In addition the pilots' chances of survival were considerably enhanced by the incorporation of a hyper drive system, which enables the ship to escape from hopeless battle situations.
When stationed on Hoth, the Rebel Alliance modified T-47 air speeders to become snowspeeders, fast flying conveyances for patrol and defense of their hidden base. It took some doing to keep the crippling cold from permanently grounding their air force, but Rebel ingenuity overcame the relentless Hoth elements. The T-47 air speeder is a small, wedge-shaped craft with two forward-facing laser cannons. In its rear arc is a harpoon gun fitted with a heavy-duty tow cable. The snowspeeder is a two-man vessel, with a pilot and rear-facing tail gunner.
