[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's capability to take on passengers and cargo without ramps or stairs, making it suitable for small-town airports with limited facilities.

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.
