The Fierce Flyers of WWII: Iconic Fighter Planes and Their Pilots

World War II, which started on September 1, 1939, and continued for exactly four years and one day, was the biggest and deadliest war in history. It was fought between two main military alliances – the Allies, led by Britain, the United States, the Soviet Union, and France, and the Axis of Power, led by Germany, Italy, and Japan. According to data from the National World War II Museum, there were 15,000,000 deaths in battle, 45,000,000 civilian deaths, and 25,000,000 wounded in battle.

The U.S. military, then comprised of the Army, Navy, Marine Corps, and Coast Guard, helped the Allies to eventual victory. The Army Air Forces (AAF), later to become the Air Force, was extremely instrumental in all theaters of WWII, contributing significantly to Allied victory with strategic bombing campaigns and air operations. By the war's end, they were the most powerful Air Force in the world.

Whether on the side of the Allies or the Axis of Power, there were several legendary fighter pilots, and WWII flying aces, who were well-trained and highly skilled in aerial combat. It wasn't an easy task, but these men made it look almost effortless, earning the respect of their peers and their place in history. (Don't miss the 20 Fastest Planes in World War II)

Here are the fierce flyers of WWII: iconic fighter planes and their pilots.

Luftwaffe officer Hartmann, who survived over 1,400 missions and had 352 confirmed kills primarily on the Easter Front, is still the most successful fighter pilot of all time. (A "kill" in this context means an enemy aircraft was shot down.) Maybe it was in his blood, as his mother was one of Germany's first female glider pilots.

"Bubi" was a nickname he got as a boy, but other flyers tagged him with the moniker "Black Devil" for his ferocity in the air.

The Messerschmitt Bf-109 (often called the Me-109 by the Allies) was Germany's most mass-produced airframe in World War II and was a veritable backbone of the Luftwaffe. They first saw action in the Spanish Civil War in 1937 and were still in use at the end of the war in 1945. Several variants kept it competitive with newer Allied fighter aircraft.

Germany produced a total of 33,984 Bf-109s between 1937 and 1945, accounting for 57% of German fighter aircraft production.

American pilot George "Ratsy" E. Preddy, Jr had already achieved three aerial victories in a P-47 Thunderbolt before reaching a total of 26 and five planes destroyed on the ground in a P-51 Mustang. The legendary Chuck Yeager nominated him for the Medal of Honor. Friendly anti-aircraft fire over Belgium downed his plane, and he later died of his wounds.

North American Aviation produced approximately 15,000 P-51s throughout World War II, in four different variants (A, B, C, & D). The Korean War saw many "D" models in action. The British modified the D models with a Rolls Royce Merlin engine for a longer range. Only about 150 of these legendary fighter planes exist today, and fewer are still capable of flight.

Official reports conflict on exact numbers but RAF Wing Commander James E. "Johnny" Johnson recorded between 34 and 38 aerial victories in about 700 missions. All his victories were against other fighter aircraft. He missed the Battle of Britain because he needed surgery to correct an injury he received when playing rugby as a younger man.

The Supermarine Spitfire's Rolls Royce PV-12 engine propelled it to 360 MPH and 34,000 feet. It was highly maneuverable and agile and very successful against German planes. England produced about 20,341 Spitfires, more than any other World War II fighter plane. It holds a beloved place among the most legendary fighter planes of WWII.

One of the top-scoring Japanese pilots of WW2, Tetsuzo "Tiger Tetsu" Iwamoto had an official record of between 87 and 98 aerial victories in combat. However, his diary, found after his death, records 202 aerial victories in the Pacific alone. He also served in China in 1938 and was credited with 14 victories.

The Mitsubishi A6M Zero holds a formidable place in history. Racking up a 12:1 kill ratio throughout the war, Zeros could out-turn and out-fly any other carrier-based fighter in the early war years. Japan built approximately 11,000 Zero fighters during the war. They surprised American pilots with their speed, maneuverability, and formidable armament.

USAAF Fighter Pilot Robert S. Johnson was the first Eighth Air Force European theater pilot to pass Eddie Rickenbacker's World War I tally of 26 aerial victories with a final total after some official juggling of 27. Johnson flew 91 combat sorties. He later worked for Republic Aviation after the war testing new aircraft designs.

Republic manufactured over 15,600 Thunderbolts during the war and every theater of combat operations saw them in action. When fully armed, a P-47 could deliver about half the payload of a B-17 Flying Fortress. Its pilots nicknamed it the "Juggernaut" (shortened to Jug) because of its strong design and armor that protected them in combat. It is the heaviest single-engine fighter airplane used during WWII.

Navy pilot David McCampbell was the highest-scoring ace in the United States Navy and the third-highest-scoring American fighter pilot of World War II. He earned 34 aerial victories and won the Medal of Honor for fighting off a group of 60 Japanese aircraft and shooting down 9 of them in a single engagement.

Due to the heavy demands of the Pacific theater of operations, the indomitable Grumman F6F Hellcat went from experimental to operational in only 18 months. Nevertheless, it is responsible for 75% of the Navy's aerial victories during the entire war. Hellcat pilots like David McCampbell turned in a 19:1 kill ratio, and this was only two years before the war ended.

Although there isn't much recorded history about Oberleutnant Otto Kittel, he was one of World War II's top Luftwaffe fighter aces, earning 267 aerial victories in 583 missions. His entire career was spent on the Eastern Front, and all his victories were against Red Air Force (Russian) opponents. He was eventually shot down in 1945 and is the most successful German fighter pilot KIA.

The Focke-Wulf Fw-190 was almost as prolific in production and use as the Bf-109, forming a substantial part of the German Luftwaffe. Its electric landing gear and wing flaps were advanced for its time. It was also the only single-seat radial engine German fighter. Focke-Wulf produced several variants, including some high-altitude models.
