Although partially overshadowed by the famous Mustang, the Republic P-47 Thunderbolt established a distinguished record as a high altitude interceptor and bomber escort. More Thunderbolts were manufactured during World War II than any other American fighter, and the seven-ton aircraft became extremely popular with USAAF pilots because of its ability to absorb extensive battle damage and remain flying. Perhaps the most outstanding tribute to this aircraft is the fact that all ten of the leading Thunderbolt aces survived the war. The P-47 could easily out dive the enemy fighters and could dish-out terrible punishment form its eight 0.50 caliber Browning machine guns.
