The P-47N was the final production model P-47 and was produced solely for action in the Pacific. It featured new, larger wings with squared-off wingtips. With additional internal fuel, the P-47N had a total fuel capacity of 1,266 gallons and a range of 2,350 miles, which was enough to permit it to escort B-29s to Japan in the last months of the War. The P-47N was powered by a 2,800hp R-2800 engine. It had a gross weight of 20,700 pounds and a high speed of 467mph at 32,500 feet. Republic built a total of 1,667 of the P-47N variant. An order for a further 5,934 planes was canceled. The P-47 was retired as a first-line fighter right after the War, but the bubble-canopy P-47Ds and P-47Ns stayed in the reserved training squadrons until 1955.
