The French Air Force aircraft engine series Hispano-Suiza V-12's last two models were used mainly around what war(s)?
Hispano-Suiza 12Z The 12Z, designated Type 89 by the company, was the final evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model had just entered production when France fell to the Germans during World War II. A small number were produced during the war but the German occupation government would not allow full-scale production to start. After the war small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development.
Ilyushin Il-4 The Ilyushin Il-4 (Cyrillic Илью́шин Ил-4, NATO reporting name: "Bob") was a Soviet World War II bomber aircraft, widely used by the Soviet Air Force (VVS, "Voenno-Vozdushnye Sily").
