F4U Corsair | All You Need To Know About Pappy Boyington's Choice of Fighters

The Vought F4U Corsair was a carrier-based fighter aircraft that saw service in World War II and the Korean War. The plane was designed and produced by Chance Vought Aircraft and had one of the longest production runs of any piston-engine fighter aircraft in history. The Corsair was designed as a carrier-based aircraft, but it proved to be so successful on land that it became one of the most widely used fighter-bombers of the war.

Demand for the aircraft soon overwhelmed Vought's manufacturing capability, resulting in production by Goodyear and Brewster: Goodyear-built Corsairs were designated FG while those built by Brewster were designated F3A.

It is estimated that over 12,500 Corsairs were built between 1940 and 1952. Today, the airplane is highly revered by aviation enthusiasts and warbird collectors alike. In this blog post, we'll take a deep dive into the history and design of this iconic American fighter plane.

Development

In 1938, The U.S. Navy Bureau of Aeronautics requested a single-engine fighter to call for a maximum obtainable speed and a stalling speed no higher than 70 miles per hour. The fighter also had to carry four guns or three with increased ammunition. The Navy specified that provision needed to be made for anti-aircraft bombs to be carried on the wing. In the 1930s, it was believed that these small bombs would be dropped on enemy aircraft formations. (which made it formidable in ground attack)

The development of the Vought F4U Corsair was a significant event for the U.S. Navy. The prototype, designated the V-166B, was signed for by Vought in June 1938.

Rex Beisel led the design team, and the XF4U-1 began shortly after the mock-up inspection in February 1939. The aircraft was powered by an XR-2800-4 prototype of the Pratt & Whitney R-2800 Double Wasp radial engine, which delivered 1,805 hp (1,346 kW). (pratt whitney R 2800)

The prototype was completed quickly and had an impressive engine, propeller, and wing. The first flight went smoothly until the elevator trim tabs failed because of flutter.

The development of the Vought F4U Corsair was not without its difficulties. The aircraft had speed and climb requirements that had to be rewritten, and in full-power dive tests, speeds of up to 550 mph (890 km/h) were achieved.

While this was impressive, it came at a cost, as the control surfaces and access panels sustained damage, and in one case, an engine failure occurred. In addition, the spin recovery standards had to be relaxed. Despite these issues, the Corsair went on to be a successful aircraft with the impressive landing gear.

Design

The F4U Corsair was designed with a large engine to extract as much power as possible. A Pratt and Whitney R-2800 Double Wasp radial provided 2,000 hp (1,500 kW). A Hamilton Standard Hydromatic three-blade propeller of 13 feet 4 inches (4.06 m) was used.

The Corsair was powered by a large radial engine and had a large propeller that made it one of the fastest aircraft in World War II. It could fly at over 400 mph (640 km/h) at altitude and had a range of over 1500 miles.

The different variants of the Corsair were outfitted with different armaments, depending on their intended role. While most variants carried the standard armament of six .50 caliber machine guns, some models were equipped with four 20 millimeter cannons.

The Corsair saw action in all theaters of the war and was the main fighter of the USMC until the jet age. After the war, it remained in service with various air forces until the early 1950s.

Operational History 

The Vought F4U Corsair was a carrier-capable fighter aircraft that saw service in World War II and the Korean War. The aircraft was first flown on 29 May 1940 and entered service with the United States Navy in December 1942. The Corsair served with the U.S. Navy until the end of the war and continued to operate until 1979.

1. U.S. Service

The Corsair first flew in 1940 and began entering service with the U.S. Navy in 1941. Initially, the aircraft was used as a fighter and bomber but was later adapted for use as a carrier-based fighter. During World War II, the Corsair saw action in both the European and Pacific Theaters and continued to be used by the U.S. Military in Korea and other conflicts in the years after the war.

2. Navy Testing And U.S.M.C

After its initial flight in 1940, the Corsair underwent testing by the U.S. Navy. The Navy was initially skeptical of the aircraft, but after the Corsair proved its worth in testing, it was released to the U.S. Marine Corps for combat use in 1942.

3. USMC Combat

The Corsair quickly proved its worth in combat and was used extensively by the USMC in Pacific and European Theaters. It was particularly effective as a fighter and bomber and was often used to ground attack enemy ground targets.

VMF-214: The Black Sheep Squadron's Wartime Record

Perhaps no Corsair squadron became more legendary than Marine Fighting Squadron 214, more famously known as the "Black Sheep." Thrown together in the Solomon Islands under the leadership of the colorful Major Gregory "Pappy" Boyington, VMF-214 assembled a group of replacement pilots—some fresh, some experienced—who quickly became a formidable force.

During two intense six-week deployments, the Black Sheep carved out an impressive reputation in the South Pacific. They were credited with downing 97 enemy aircraft and inflicting damage on more than 100 others, putting them near the top of the scoreboard among Marine squadrons at the time. Their daring tactics, relentless spirit, and remarkable combat success sealed their status as one of WWII's most celebrated aviation units.

VMF-214’s Unique Approach to Aircraft Assignment and Upkeep

When VMF-214—better known as the “Black Sheep Squadron”—deployed to the South Pacific, their methods for managing their Corsair fighters were anything but standard. Formed in 1943 from a patchwork of replacement pilots, the squadron adopted a flexible approach to aircraft assignment. Instead of each pilot having a dedicated Corsair, planes were rotated among squadron members based on availability and operational readiness. As a result, it was common for pilots to head into combat in whichever Corsair was prepped and ready that day—sometimes flying a different aircraft from one mission to the next.

Major Gregory “Pappy” Boyington, the squadron’s charismatic leader, set the tone for teamwork and resilience. He made a habit of taking up the Corsair in the roughest shape before heading out on a mission, sparing the other pilots from potential mechanical headaches. This practice not only boosted morale but also demonstrated a fierce sense of camaraderie and leadership that became a hallmark of the Black Sheep.

Their unconventional, collective approach—combined with rigorous teamwork on the ground—kept their fleet operational and mission-ready, making VMF-214 one of the standout units in the Pacific theater.

4. Field Modifications For Land-Based Corsairs

To make the Corsair more suitable for use on land, the Marine Corps made several field modifications to the aircraft. These modifications included adding wheel pants and a tailhook and increasing the fuel capacity.

5. Fighter-Bomber

The Corsair was particularly effective as a fighter-bomber and was often used to attack enemy ground targets.

6. Navy Service

After the war, the Corsair continued to be used by the U.S. Navy in several different roles, including as an aircraft carrier and fighter-bomber. The aircraft saw action in both the Korean War and the Vietnam War.

7. Royal Navy

In addition to the U.S. military, the Corsair was also used during World War II. The British Royal Navy made several modifications to the aircraft to make it more suitable for use on carrier decks, including adding arrestor hooks and increasing the fuel capacity.

The Corsair was first deployed by the Royal Navy in 1943 as a fleet air arm service and saw action in both the European and Pacific Theaters during World War II.

8. Royal New Zealand Air Force

The Royal New Zealand Air Force also used the Corsair during World War II. The aircraft saw action in the Pacific Theater and was particularly effective against Japanese ground targets.

Many Corsairs were captured by the Japanese during World War II and were used by the Japanese military in various roles, including as fighters and kamikaze aircraft.

9. Korean War

The Corsair continued to be used by the U.S. military in Korea after World War II and saw action in both the air-to-air and air-to-ground roles.

10. Aéronavale

The French Aéronavale first used the Corsair in the First Indochina War in 1949. The aircraft saw action in various roles, including as a fighter, attack aircraft, and night fighter.

11. French Experiments

In addition to its use by various military forces, the French Air Force also used the Corsair for some experimental purposes, including as a test aircraft for new weapons and equipment.

Legacy

The Corsair was a carrier fighter that saw service in 1942. However, its low-speed handling was tricky due to the left-wing stalling before the right-wing. Together with poor visibility over the long nose, this factor made carrier landings a difficult task.

For these reasons, most Corsairs initially went to Marine Corps squadrons which operated off land-based runways. USMC aviators welcomed the Corsair with open arms as its performance was superior to the fighter squadrons and corsair pilots.

The Vought F4U Corsair was a powerful fighter aircraft that could outperform the Japanese A6M Zero. The Corsair was faster, had a higher maximum speed and could climb and dive better than the Zero, making it a deadly opponent in combat. The Corsair's six .50-caliber machine guns could also do a lot of damage, giving the marine pilots enough firepower to take down an enemy plane as well as provide close air support.

During World War II, the Vought F4U Corsair was a highly effective aircraft, earning nicknames such as "The Sweetheart of the Marianas" and "The Angel of Okinawa" from infantrymen. Navy and Marine aviators also nicknamed the aircraft "Ensign Eliminator" and "Bent-Wing Eliminator" due to the increased amount of training required to fly it compared to other carrier-borne aircraft. It was also the favorite aircraft of Gregory Pappy Boyington of the Black Sheep Squadron.

Many also know the Corsair as the "U-bird" or "Bent Wing Bird." Although it is commonly claimed that the Japanese called the Corsair the "Whistling Death," Japanese sources do not support this. Instead, they mainly knew it as the Sikorsky.
