context_page_description: The P-47 Thunderbolt was a World War II fighter aircraft built by Republic Aviation from 1941 to 1945.
context_section_description: In an attempt to improve the performance of the Thunderbolt, Republic began a project to install a 2,300 hp Chrysler XIV-2220-1 16-cylinder inverted-V engine in two P-47D-15-RE airframes in August 1943.  The resulting XP-47H had a new streamlined nose with a large intake and was expected to have a maximum speed of 490 mph.  While sources do not agree whether the aircraft met the speed expectations or fell short, by the time the aircraft were modified in 1945, the Jet Age was beginning and the USAAF was losing interest in piston-engined fighters, and the XP-47H project was canceled.
