The French Air Force aircraft engine series Hispano-Suiza V-12's last two models were used mainly around what war(s)?
Hispano-Suiza 12Y The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force in the pre-WWII period. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520. Its design was based on the earlier and somewhat smaller, 12X. A further development was under way, the 12Z, but ended due to the German occupation of France.
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 By the time of the outbreak of World War II in September 1939, all of the NiD.62s had been withdrawn from front-line fighter escadrilles but were used as trainers in French flight schools.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.
