The attached article is from a 1945 Collier's Magazine and can be printed; it expounds on the evolution of the P-47 Thunderbolt through varying stages of development into the fuel-efficient juggernaut called the P-47N. Remembered in the World War II annals as the dependable escort of the B-29 Super fortresses that bedeviled the axis capitals during the closing months of World War II.
"No sacrifice was made in ammunition, guns or protective armor to provide the P-47N with this long range. It still carries eight 50.-caliber guns, four in each wing. It also can carry 10 five-inch rockets which pack the destructive power of five-inch artillery or naval shells."
