When an effective propeller solution was not found, a basic paddle type from Curtiss was fitted instead as was a Pratt & Whitney R-2800-57 of 2,800 horsepower.Armament was reduced to 6 x .50 caliber machine guns and internal fuel capacity was lowered.
The XP-47J went on to clock an impressive 500 miles per hour in March of 1944.Another Few Developmental P-47s The XP-47H was an interesting P-47 development in that it attempted to mate the P-47 airframe with the Chrysler XI-2220-1 16-cylinder, inverted-vee, liquid-cooled engine of 2,300 to 2,500 horsepower (sources vary).Two P-51D-15 models were used in this conversion test sans their armament.The complicated and untested engine proved highly unfeasible and overly complicated to fit into the existing airframe without major modifications. First flight was achieved in July of 1945, achieving a paltry 414 miles per hour for the USAAF - far lower than the projected 490 miles per hour originally envisioned (and reportedly reached) by Republic. The XP-47J was a Republic attempt to reduce the overall weight of the airframe while increasing the overall output of the engine.The original idea was to fit an R-2800-61 with a contra-rotating propeller system mated to a General Electric turbosupercharger.Rough-Hewn P-47's From Curtiss-Wright The P-47G was the designation assigned to Curtiss-Wright built Thunderbolts and were essentially C-models reincarnated under the Curtiss-Wright production banner.
Quality control was somewhat lacking at the Curtiss-Wright plant in Buffalo, New York, and production as a whole was rather slow - this being much different than the standards at the Republic facility or the Indiana plant.
As such, production of G-models was limited to a low total of 354 examples before the plant was closed.
Many of these Thunderbolts remained stateside for pilot training, never to see combat action.
After Army testing revealed less than the 500 mile per hour figure, coupled with the fact that the XP-47J would require essentially an all-new tool production line, the project was dropped in favor of the XP-72 "Wasp Major" Super Thunderbolt development.
The XP-72 proved an impressive beast herself but the changing war environment negated the need for such an implement and she was never produced.
The XP-47K was an experimental P-47D production model fitted with a Hawker Typhoon bubble canopy and cut-down rear fuselage spine to help improve pilot vision to his all-important rear quarter.
