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.
List of aircraft of World War II The List of aircraft of World War II includes all the aircraft used by those countries which were at war during World War II from the period between their joining the conflict and the conflict ending for them. Aircraft developed but not used operationally in the war are in the prototypes section at the end. Prototypes for aircraft that entered service under a different design number are ignored in favour of the service version. The date the aircraft entered service, or was first flown if the service date is unknown or it did not enter service follows the name, followed by the country of origin and major wartime users. Aircraft used for multiple roles are generally only listed under their primary role unless specialized versions were built for other roles. Aircraft used by neutral countries such as Spain, Switzerland and Sweden or countries which did no significant fighting such as most of those in South America (except Brazil), are not included.
