The Republic P-47 Thunderbolt – known as the “Juggernaut” or, simply, the “Jug” – demonstrated its prowess throughout World War II, excelling in both the European and Pacific Theaters. Famous for its versatility in aerial and ground combat, the American fighter was highly favored by Allied pilots and posed a significant challenge to Axis forces.
Here are 16 facts about this iconic aircraft.
The Republic P-47 Thunderbolt had a massive propeller
The P-47 Thunderbolt featured an exceptionally large propeller, measuring just over 13 feet in diameter. Powered by a Pratt & Whitney R-2800-59 engine, this substantial propeller necessitated design adaptations by engineers. Among these adjustments was the use of a longer-than-normal retractable landing gear, the only solution to ensure the propeller cleared the ground.
Heavy firepower
Given its role as a fighter aircraft, it’s only natural that the P-47 Thunderbolt was armed to the brim with firepower. The D-40 variant was equipped with eight M2 Brownings capable of firing 425 each and 10 High Velocity Aircraft Rockets (HVARs). It could also carry up to 2,500 pounds of bombs.
The Republic P-47 Thunderbolt featured an innovative cockpit
To ensure pilots weren’t uncomfortable in the heat of battle, the P-47 Thunderbolt was equipped with an innovative cockpit. Not only was it rather roomy, but it also featured electric fuel indicators, adequate ventilation, air-conditioning and variable heating for the gun bay. On top of this, the seat was incredibly comfortable, with some pilots comparing it to a lounge chair.
The D variant of the aircraft introduced the bubble canopy, which increased visibility.
Speaking of the ‘D’ variant…
The classic version of the P-47 Thunderbolt was the D variant, which was introduced in the middle of the Second World War. The conflict had meant the US Army Air Forces needed to accelerate improvements to its fighters, and this new variant benefited from this work.
The P-47D featured a better turbocharger, a more powerful engine, an emergency booster function, tires that could withstand the roughest of airstrips and improved armor. It also saw the addition of the aforementioned bubble canopy, as well as the drop tanks and the ability to carry bombs.
Proving impressive, even in the prototype phase
The P-47 Thunderbolt demonstrated its excellence from its earliest stages through to its final form. In its prototype phase, designated as the XP-47B, and took its first flight on May 6, 1941. Despite facing challenges like an oil leak that caused cockpit smoke, the test flight was deemed a success.
Tragically, the XP-47B was lost in an accident, but not before giving an impressive performance, reaching a top speed of 412 MPH at an altitude of 25,800 feet. This remarkable performance captured the attention of the US Army Air Forces (USAAF), leading to an order of 171 units. The initial delivery of these units started in December.
Heaviest single-seat piston fighter in the world
While fighter aircraft are typically designed to be lightweight to enable easy maneuverability during enemy engagements, the P-47 Thunderbolt defied this expectation. The aircraft weighed 10,000 pounds when empty. and with fuel, ammunition and the pilot, it reached a staggering eight tons, making it heavier than some Luftwaffe bombers.
Ideal for escort roles
Given its agility and fuel capacity, the P-47 Thunderbolt was perfect for escorting bombers. While on strategic bombing missions, it played a dual fighter-bomber role, shooting ground targets and using belly shackles to carry and drop bombs.
With continued success in the skies, the US Army Air Forces wound up making the P-47 its primary fighter-bomber.
Adding an auxiliary fuel tank
Range is incredibly important during bombing runs, which involve flying for hundreds of miles before encountering the planned target. With the P-74C Thunderbolt, an auxiliary fuel tank was added, which could be dropped once it was empty, lightening the aircraft’s load.
These auxiliary tanks were carried on combat raids, beginning in March 1944, letting the P-47C escort bombers all the way to the German capital of Berlin. By the time the P-47D was introduced, the fighter could carry up to three drop tanks, providing it with an impressive range.
Most produced American fighter aircraft of World War II
The American public dedicated themselves to manufacturing aircraft for those fighting in Europe and the Pacific, and the fighter that saw the most units leave the production line was the P-47 Thunderbolt. A total of 15,683 were produced, which comes as no surprise, given how successful it was in the skies over enemy territory.
The Republic P-47 Republic participated in over 700,000 sorties
Despite the impression created by its size and weight, the P-47 Thunderbolt was an agile aircraft that became incredibly popular among pilots. While it was ultimately replaced in its long-range escort role in Europe by the North American P-51 Mustang, the fighter flew in over 746,000 sorties, with an aerial kill ratio of 4.6:1.
Flown by Gabby Gabreski
Among the pilots to fly the P-47 Thunderbolt was American air ace Gabby Gabreski, who earned the title in the Second World War and in Korea. Gabreski flew the fighter while assigned to the 56th Fighter Group, and by the end of World War II had 28 confirmed kills, with three additional aircraft destroyed on the ground.
Capable of surviving substantial damage
Both the P-47 Thunderbolt’s large body and its radial engine were able to survive substantial damage, making it incredibly safe to fly in combat. This meant that pilots knew that when they entered the cockpit they’d return to base.
Republic P-47M Thunderbolt
Built for speed following the advent of the V-1 flying bomb and jet technology, the Republic P-47M was capable of hitting a top speed of 473 MPH. However, the addition of a new engine, supercharger and brakes only resulted in new issues, which delayed the aircraft’s debut to just a few weeks before the war in Europe ended in May 1945.
The first issue, a cracked ignition harness, was found after one of the P-47Ms crashed. This was followed by the discovery of a problem with the fuel carburetor diaphragm and rust in the pistons.
What about the ‘N’ variant?
With the war in the Pacific raging on, the P-47M Thunderbolt was updated to include a longer-span wet-wing with squared-off wingtips. This upgrade not only gave pilots more control when it came to turning, but also afforded an increased fuel capacity, with the N variant capable of flying 2,350 miles.
The Republic P-47 Thunderbolt saw active service with the Allies
Several Allied countries outside of the United States flew the P-47 Thunderbolt. The Royal Air Force (RAF) received 250 units of the D variant, designated the “Thunderbolt Mark I,” and 590 P-47D-25s, dubbed the “Thunderbolt Mark II.” As well, the Free French Air Forces (FAFL) received 446 P-47Ds, which aided in their efforts in both France and Germany.
On top of this, the Brazilian Air Force’s 1st Fighter Squadron flew 48 P-47Ds during the Italian Campaign, with a section of the Mexican Air Force, under the purview of the US Army Air Forces, operating the fighters in the Philippines.

While the Soviet Union received the P-47 Thunderbolt, the Red Army wasn’t all that impressed with the aircraft. Instead, it was decided the Ilyushin Il-2 would be the Russians’ primary fighter, with over 38,000 being built over the course of WWII.
