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.
Heinkel He 115 The Heinkel He 115 was a World War II "Luftwaffe" seaplane with three seats. It was used as a torpedo bomber and performed general seaplane duties, such as reconnaissance and minelaying. The aircraft was powered by two 960 PS (947 hp, 720 kW) BMW 132K nine-cylinder air-cooled radial engines. Some later models could seat four, had different engines or used different weapon arrangements.
