What is the P-47 aircraft?
The P-47 Thunderbolt, a single-seat fighter and fighter-bomber, was used by Allied air forces during World War II. Designed by Alexander Kartveli for the U.S. Army Air Forces, it was the largest single-engined piston fighter ever produced.
The P-47D, which was generally in service by the spring of 1944, could reach a maximum speed of 440 miles per hour and a ceiling of 40,000 feet. It was heavily armed with eight wing-mounted 0.50-inch machine guns, and it could carry a bomb load of 2,500 pounds, as well as ten 5-inch rockets under the wings. The P-47's greatest contribution to Allied victory was arguably as a long-range bomber escort in Europe.

When and why was the P-47 developed?
The P-47 Thunderbolt, a single-seat fighter and fighter-bomber, was developed by Republic Aviation for the U.S. Army Air Forces (USAAF) during World War II.
Republic designer Alexander Kartveli proposed the P-47 in June 1940, planning to base the fighter on the new Pratt & Whitney R-2800 twin-row radial engine, which was turbo-supercharged for high-altitude performance. The first prototype flew in June 1941, and production commenced in March 1942.
The P-47 played a crucial role in Allied victory, especially as a long-range bomber escort in Europe. It was heavily armed and known for its effectiveness as a fighter-bomber. By the spring of 1944, the P-47D could reach a maximum speed of 440 miles per hour and had a ceiling of 40,000 feet.

What was the main role of the P-47 during World War II?
The P-47 Thunderbolt, a single-seat fighter-bomber, was vital to the Allied air forces during World War II. Armed with eight 0.50-inch machine guns, it could carry up to 2,500 pounds in bombs and ten 5-inch rockets.
The P-47's contribution to Allied victory was as a long-range bomber escort in Europe. As a fighter-bomber, it played a role in the Normandy Invasion, attacking bridges, enemy airfields, and German armored vehicles. The P-47 also proved to be effective as a ground-attack aircraft. The Thunderbolt outnumbered the P-38 Lightnings and P-51 Mustangs combined. It served with the Army Air Forces in the Pacific from the summer of 1943 and with Britain’s Royal Air Force in India and Burma.

What were some key features of the P-47’s design?
The P-47, a single-seat, low-wing fighter-bomber, was the largest single-engine piston fighter ever produced. It used a Pratt & Whitney R-2800 twin-row radial engine, turbo-supercharged for high-altitude performance. It had a maximum speed of 440 miles per hour and a ceiling of 40,000 feet. Heavily armed, the P-47 had eight wing-mounted 0.50-inch machine guns, could carry a bomb load of 2,500 pounds, and ten 5-inch rockets under the wings. Its engine and armored cockpit proved remarkably resistant to battle damage. The P-47's greatest contribution was arguably as a long-range bomber escort in Europe.

How did the P-47 compare to other fighter planes of its era?
The P-47 Thunderbolt, a single-engine fighter-bomber, was heavily armed with eight .50-inch machine guns and could carry a substantial bomb load. It was known for its ruggedness, with its radial engine and well-armored cockpit proving resistant to battle damage.
While the P-47 was as fast as German Me 109s and Fw 190s on the level and could outdive anything, it could not outclimb or outturn them at low altitudes. However, its turbo-supercharged engine gave it an advantage above 30,000 feet. The P-51 Mustang, with a Rolls-Royce Merlin engine, became the outstanding high-altitude escort fighter of the war and was competitive with the Spitfire, Bf 109, and Fw 190 in speed, climb rate, and maneuverability, with a greater radius of action. The Fw 190, a German fighter, was an outstanding air-to-air fighter with excellent maneuverability and heavy armament, holding its own against Allied fighters until the Spitfire IX.

What impact did the P-47 have on air combat during the war?
The P-47 Thunderbolt significantly impacted air combat during World War II. As a fighter-bomber, it played a crucial role in the Normandy Invasion, striking bridges, enemy airfields, and German armored vehicles. The P-47's greatest contribution was arguably as a long-range bomber escort in Europe.
The P-47 was heavily armed with eight .50-inch machine guns and could carry a substantial bomb load. Although German Me 109s and Fw 190s outmaneuvered it at low altitudes, the P-47 was faster at level flight and had the advantage above 30,000 feet due to its turbo-supercharged engine. Its rugged radial engine and armored cockpit made it exceptionally resistant to battle damage, establishing its reputation as an effective ground-attack aircraft. The Thunderbolt outnumbered other U.S. fighters in Europe and also served in the Pacific and with the British Royal Air Force.

P-47, fighter and fighter-bomber used by the Allied air forces during World War II. A single-seat low-wing fighter developed for the U.S. Army Air Forces (USAAF) by Republic Aviation, it was the largest single-engined piston fighter ever produced.
The P-47 originated with a June 1940 proposal by Republic designer Alexander Kartveli to base a fighter on the new Pratt & Whitney R-2800 twin-row radial engine, turbo-supercharged for high-altitude performance. Harnessing the power of the huge engine posed problems, and the first prototype did not fly until June 1941. Production did not commence until March 1942, and even then difficulties were caused by shock waves that formed in high-altitude dives when the local airflow approached the speed of sound, causing the flight controls to “snatch” and in some cases lock. The controllability problems were eventually resolved, but it was mid-April 1943 before the P-47 entered combat over Europe.
A total of 15,683 Thunderbolts were produced by war’s end, more than any other U.S. fighter. The P-47D, in general service by the spring of 1944, had a maximum speed of 440 miles (700 km) per hour and a ceiling of 40,000 feet (12,200 metres). Heavily armed with eight wing-mounted 0.50-inch (12.7-mm) machine guns, it could carry a bomb load of as much as 2,500 pounds (1,100 kg) and could carry ten 5-inch (127-mm) rockets beneath the wings. The P-47’s radial engine proved remarkably resistant to battle damage, and, with its heavy armament and well-armoured cockpit, the Thunderbolt established a reputation as one of the most effective fighter-bombers of the war. Though the Thunderbolt was outclimbed and outturned by German Me 109s and Fw 190s at low altitudes, it was as fast as the Luftwaffe fighters on the level and could outdive anything. More important, its turbo-supercharged engine gave the P-47 the advantage at altitudes above 30,000 feet (9,100 metres).

The P-47’s greatest contribution to Allied victory was arguably as a long-range bomber escort in Europe, though delays in developing and fielding jettisonable external fuel tanks (necessary for range extension) limited the plane’s impact in this role until early 1944. As a fighter-bomber, it played an important part in the Normandy Invasion, attacking bridges and enemy airfields before the D-Day landings on June 6 and destroying German armoured vehicles during the Allied breakout from the lodgement area.
The most important U.S. fighter in Europe numerically, outnumbering P-38 Lightnings and P-51 Mustangs combined, the Thunderbolt also served with the Army Air Forces in the Pacific from the summer of 1943 and with Britain’s Royal Air Force in India and Burma (Myanmar). Though it served with the U.S. Air National Guard for several years after the war, the P-47 was retired from front-line service after the victory over Japan in 1945.
