The Republic P-47D Thunderbolt entered U.S. Army Air Forces service in 1942 and became one of the main fighter-bombers of World War II. It was renowned for its durability, heavy armament (eight .50-caliber machine guns), and ability to carry bombs and rockets, making it highly effective in both air-to-air combat and ground-attack missions. The P-47D served in Europe, the Pacific, and Mediterranean theaters, providing close air support, bomber escort, and tactical strike capabilities until the end of the war.
