The French Air Force aircraft engine series Hispano-Suiza V-12's last two models were used mainly around what war(s)?
Hispano-Suiza 12Z The 12Z, designated Type 89 by the company, was the final evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model had just entered production when France fell to the Germans during World War II. A small number were produced during the war but the German occupation government would not allow full-scale production to start. After the war small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development.
Potez-CAMS 161 The Potez-CAMS 161 was a large, French six-engined flying boat airliner, designed to operate on the North Atlantic routes that were opening up in the late 1930s. Its development was almost halted by World War II. Just one was built and partially tested before its destruction by Allied forces near the war's end.
