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.
11me Escadrille de Chasse The 11ème Escadrille de Chasse was the third and last fighter squadron of the Belgian Air Component during World War I. It was organized as a dedicated fighter unit in March 1918, to fill out a fighter wing that supported the Belgian Army's advance near war's end.
