61st FS, 56th FG - Nicknamed "JUG", the P-47-D was one of the most important and most produced fighters of the American Air Force during the WWII. Although the P-47D was the largest and heaviest single-seat aircraft to see service in the Second World War, it became a high speed and high altitude capable fighter when powered by the huge 2000hp Pratt & Whitney R-2800 "Double Wasp" engine and a unique supercharging system. Shaped with a sharp upper ridge, the early types of P-47D were given a name "Razorback". During the war, the Razorbacks served as striking fighters and sometimes escort fighters of the allied bombers when conducting raids over Germany.
