Production 15,660 of all types from 3/42 to 9/45 at Republic Aviation Corporation, Farmingdale, NY:

  1 XP-47B

171 P-47B

602 P-47C

12,602 P-47D

354 P-47G built by Curtiss-Wright (otherwise identical to the D)

1 XP-47J

130 P-47M

1816 P-47N

The P-47B used a 2000 hp (1491 kW) R-2800-21 engine and lacked provisions for a drop tank or bombs.

The P-47C added drop tanks (but not bombs) and improved the maneuverability by shifting the engine slightly.

The P-47D introduced the bubble canopy.

The P-47N introduced the 2800 hp (2088 kW) R-2800-57 engine and increased the range to 2300 miles (3700 km.)

The P-47 Thunderbolt, also known as the “Jug,” was one of the best fighter-bombers of the war. Though huge for a fighter, it was very fast, had excellent high-altitude performance, could drop like a rock, had a surprisingly good roll rate for such a large airframe, and was extremely rugged, with its large air-cooled engine acting almost as a thick layer of armor protecting the pilot.

The design dated to 1940, when Republic's chief engineer, Alexander Kartveli, scrapped existing plans for a lightweight fighter, the P-10, and began designing a fighter built around the new turbocharged R-2800 engine and incorporating the early war lessons of the Allies in Europe. The design proved challenging, particularly with respect to the long landing gear required to give sufficient clearance for the large propeller, and the prototype was not complete until 6 May 1941 and the design was not approved for production until early 1942.

The fighter was initially met with skepticism by RAF pilots who were used to dogfighting in cramped but nimble fighters like the Spitfire, and the joke went around that the only way to take evasive maneuvers in a P-47 was to unstrap and run in circles in the cockpit. However, the P-47 excelled at the hit-and-run tactics that were already proving superior to traditional dogfighting. It could also carry a heavier bomb load than most light bombers could at the start of the war. It had an effective combat radius of almost 450 miles with two 108-gallon (409-liter) drop tanks.

The cost of production droppped from $105,594 in 1942 to $83,001 in 1945.

The Thunderbolt played both the roles of high-altitude escort and low-level attack aircraft with success. Though its greatest successes were in Europe and the Mediterranean, it played a significant role in the Southwest Pacific as well. Some remained in service with smaller air forces until the 1950s. About 28% of Thunderbolt crews were deployed to the Pacific.
