The Republic P47 Thunderbolt is a World War IIera fighter aircraft produced by the American aerospace company Republic Aviation from 1941 through 1945. Its primary armament was eight .50caliber machine guns, and in the fighterbomber groundattack role it could carry 5inch rockets or a bomb load of 2,500 lb (1,100 kg). When fully loaded, the P47 weighed up to 8 tons, making it one of the heaviest fighters of the war.
The Thunderbolt was effective as a shortto mediumrange escort fighter in highaltitude airtoair combat and ground attack in both the European and Pacific theaters. The P47 was designed around the powerful Pratt & Whitney R2800 Double Wasp 18cylinder radial engine, which also powered two U.S. Navy/U.S. Marine Corps fighters, the Grumman F6F Hellcat and the Vought F4U Corsair. An advanced turbosupercharger system ensured the aircraft's eventual dominance at high altitude, while also influencing its size and design.
The P47 was one of the main United States Army Air Forces (USAAF) fighters of World War II, and also served with other Allied air forces, including those of France, the United Kingdom, and the Soviet Union. Mexican and Brazilian squadrons fighting alongside the USAAF also flew the P47.
The armored cockpit was relatively roomy and comfortable and the bubble canopy introduced on the P47D offered good visibility. Nicknamed the "Jug" owing to its appearance if stood on its nose, the P47 was noted for its firepower, as well as its ability to resist battle damage and remain airworthy. A presentday U.S. groundattack aircraft, the Fairchild Republic A10 Thunderbolt II, takes its name from the P47.
By the end of 1942, P47Cs were sent to England for combat operations. The initial Thunderbolt flyers, 56th Fighter Group, was sent overseas to join the 8th Air Force. As the P47 Thunderbolt worked up to operational status, it gained a nickname: "Jug" (because its profile was similar to that of a common milk jug of the time). Two fighter groups (FGs) already stationed in England began introducing the Jugs in January 1943 the Spitfireflying 4th Fighter Group, a unit built around a core of experienced American pilots who had flown in the RAF Eagle Squadrons prior to the US entry in the war; and the 78th Fighter Group, formerly flying P38 Lightnings.

Beginning in January 1943, Thunderbolt fighters were sent to the joint Army Air Forces – civilian Millville Airport in Millville, New Jersey, to train civilian and military pilots.
The first P47 combat mission took place 10 March 1943 when the 4th FG took their aircraft on a fighter sweep over France. The mission was a failure due to radio malfunctions. All P47s were refitted with British radios, and missions resumed 8 April. The first P47 air combat took place 15 April with Major Don Blakeslee of the 4th FG scoring the Thunderbolt's first air victory (against a FockeWulf Fw 190).
