This is a walkaround of the
Republic P-47N-25-RE, S/N 44-89320, displayed at the  U.S. Air Force Armament Museum, adjacent to Eglin AFB.

The P-47N version of the Thunderbolt was the last version to be manufactured in quantity. It was a specialized long-range version built specifically for service in the Pacific theatre. However, the war in the Pacific required fighter ranges even greater than did operations over Germany. In pursuit of better long-range performance, in mid-1944 the third YP-47M prototype (42-27387) was fitted with a new "wet" wing of a slightly larger span and area. The aircraft was redesignated XP-47N. For the first time in the Thunderbolt series fuel was carried in the wings, a 93 US gallon tank being fitted in each wing. 

The new wing also incorporated larger ailerons and squared-off wingtips. These innovations enhanced the roll-rate of the Thunderbolt and improved maneuverability. The dorsal fin behind the bubble canopy was somewhat larger than that on the P-47D. However, the increased fuel load increased the gross weight of the aircraft. In order to cope with the increased gross weight, the undercarriage of the XP-47N had to be strengthened, which increased the weight still further. The maximum weight rose to over 20,000 pounds

The XP-47N flew for the first time on July 22, 1944. The P-47N was destined to be the last version of the Thunderbolt to be manufactured. The first P-47N-1-RE appeared in September of 1944, and 24 were delivered by year's end. The P-47N-5-RE and subsequent batches had zero-length rocket launchers added. The R-2800-77 engine was installed in late production models such as the P-47N-25-RE.

The P-47N gave excellent service in the Pacific in the last year of the War, particularly in escorting B-29 Superfortress bombers in raids on the Japanese mainland. P-47Ns were able to escort the bombers all the way from Saipan to Japan and on many other long, overwater flights.

A total of 1667 P-47Ns was produced by the Farmingdale plant between December 1944 and December 1945, when the Thunderbolt line finally closed down. 149 more P-47Ns were built by the Evansville factory.

Serials of the P-47N were:

This is a short walkaround I made during a visit to the U.S. Air Force Armament Museum, at Eglin on nov/2019. This particular example was displayed at Muniz Air Base, Puerto Rico, then restored at San Juan. It flew again on 20 September 1972. During 1970–1978 it was civil registered as N345GP, flown as 489320, coded 5A-2. Damaged, tipped on nose, propeller damaged, Myrtle Beach AFB, South Carolina, 10 June 1977. Still there in March 1979. Impounded by US Government due to breach of sale conditions.

It is currently marked as P-47N-5-RE, 44-88129, "Expected Goose",
of the 463rd Fighter Squadron, 507th Fighter Group while stationed at Ie Shima Island near Okinawa in 1945. The unofficial emblem of the 463rd FS, a duck wearing a flight helmet with two P-47 underwing tanks, is painted on the fuselage under cockpit. It is in flyable condition.

I hope you find these photos useful somehow. If you have any interesting information about the history of this aircraft, please drop me a line.
