The Lockheed Model 75 Saturn was a small feeder airliner produced by the Lockheed Corporation in the mid-1940s. Lockheed announced the project on November 19, 1944.[1] The design team, led by Don Palmer, created a high-wing, twin-engine monoplane with 14 seats and a top speed of 228 mph (367 km/h). Lockheed touted the Saturn as an airliner to service small towns with limited airport facilities and could take on passengers and cargo without ramps or stairs.[2]

Tony LeVier piloted the first flight on June 17, 1947. Lockheed had received 500 conditional orders for this aircraft, priced at $85,000 each. But, by the time the design was completed, the selling price had risen to $100,000 and these orders had been cancelled, with war surplus C-47s filling the same market at a quarter the price. Lockheed lost $6 million from the development of the two prototypes, which were scrapped in 1948.
