Remarks by Johan Visschedijk: "As a first departure from its low-wing design traditions, Lockheed in 1946 built two Saturns to evaluate the possible demand for high-speed feeder airline or executive aircraft. Prominent features were the high wing, long dorsal fin extending to mid-fuselage and a stand-up observation window near the empennage. The second prototype c/n 075-1002 was most likely never flown as it was never registered. Both aircraft were scrapped in early 1948."
