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.
Nieuport-Delage NiD 62 The Nieuport-Delage NiD.62 was a French sesquiplane fighter from the early 1930s. This machine was a descendant of a long line of Nieuport-Delage fighters that were designed and built during the years immediately after World War I. The NiD.62 was built in 1931 as a fighter for the "Armée de l'Air". It served until the late 1930s, when it was replaced by more modern monoplane fighters. By the time of the outbreak of World War II in September 1939, all of the NiD.62s had been withdrawn from front-line fighter escadrilles but were used as trainers in French flight schools. A few aircraft were employed as target tugs. After the French capitulation and German occupation of France in June 1940, the German "Luftwaffe" had no interest in the NiD.62s and they were scrapped. None survived the war.
