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.
Macchi C.202 The Macchi C.202 "Folgore" (Italian "thunderbolt") was a World War II fighter aircraft built by Macchi Aeronautica and operated mainly by the "Regia Aeronautica" ("RA"; Royal (Italian) Air Force). Macchi aircraft designed by Mario Castoldi received the "C" letter in their model designation, hence the "Folgore" is referred to as the C.202 or MC.202. The C.202 was a development of the earlier C.200 "Saetta", with an Italian-built version of the Daimler-Benz DB 601Aa engine and a redesigned, more streamlined fuselage. Considered to be one of the best wartime fighters to serve in large numbers with the "Regia Aeronautica", the "Folgore" operated on all fronts in which Italy was involved.
