SNCAC NC.150

The SNCAC NC.150 was a prototype French high-altitude bomber aircraft designed and flown just prior to the start of the Second World War. It was a twin-engined monoplane, with a third engine driving a supercharger. Although testing was promising, and orders were planned for a modified version as a back-up for the Lioré et Olivier LeO 45 and Amiot 354 bombers, the surrender of France in June 1940 ended development with only the single example being built.
