"The SNCAC NC.150 (also known as the Centre 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."
"NC.150.01 First prototype. Not fitted with pressurisation and unarmed.
NC.150.02 Second prototype. Unpressurised but to be fitted with full armament. Not completed.
NC.151.03 Third prototype, representing original bomber design, with pressure cabin and full armament. Not completed.
NC.152 Planned production version powered by two supercharged Hispano-Suiza 12Y engines.
NC.153 Planned production version powered by two supercharged 1,850 hp (1,380 kW) Pratt & Whitney R-2800 S1A4-G Double Wasp radial engines."
