The Arctic Aircraft Arctic Tern (named after the bird) is a bush plane that was produced in small numbers in Alaska in the 1970s and 1980s. It is a strengthened and modernised version of the Interstate Cadet of the 1940s. It is a high-wing braced monoplane with fixed tailwheel undercarriage. It has two seats in tandem, with the rear seat removable for added cargo carriage. It is also provided with a cargo loading door in the fuselage side to facilitate loading bulky items. Optional fittings included floats or skis in place of the wheeled undercarriage, and a ventral pod to carry extra cargo or fuel.

In 2007, the Interstate Aircraft company was planning a revised and updated Arctic Tern, with US FAA certification expected in the first half of the year.
