Immediately after the Second World War, the American company Republic, began working on a new turbo-jet fighter-bomber. F.84 Thunder jet was developed on a simple but effective design with a large frontal air intake, straight wings and a robust tricycle landing gear. Thanks to the General Electric/Allison J35 turbo-jet engine, F-84 Thunder jet was able to reach 1,000 Km/h. It was armed with six 12.7 mm machine guns and it could carry an offensive load of nearly 900 kg. The F-84G, entered production in 1951, is one of the latest versions of the Republic fighter-bomber. In addition to the USAF it was used by many NATO countries, including several fighter-bomber squadrons of Italian Aeronautical Military, in accordance with the Mutual Defense Assistance Act.
