When stationed on Hoth, the Rebel Alliance modified T-47 airspeeders 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 airforce, but Rebel ingenuity overcame the relentless Hoth elements. The T-47 airspeeder 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 tailgunner.
