Fighter Plane – 15,000 Built

Mustang Front View

The P-51 Mustang is one of the most famous fighters of WWII and of all time thanks to its exceptional performance characteristics, strong airframe and the role this fighter plane played in the European Theatre against the German Luftwaffe. Contributing to its defeat and aiding the Allies in gaining full control of the skies. It was also a long-enduring aircraft, with the last ones retired in 1984. It was by far the best day and night-time fighter of the Allies’ arsenal, with the Lockheed P-38 being its closest in-service rival.

The Origins of the Mustang

The Mustang was a single-seat and single engine fighter/fighter-bomber for day and night-time, with low wings. Its development began after a 1940 request by the Royal Air Force (RAF) for further license-built Curtiss P-40 Fighters to the North American Aviation. The British realized that bombing missions over German occupied territories were risky, suffering heavy casualties at the hands of the highly skilled Luftwaffe pilots and their fighters. The company made a move that would have a ripple effect throughout history, as it proposed to develop a new fighter instead of issuing the RAF an old model that was in short supply. The P-40 chain of production was already overloaded, with the P-40 component manufacturers reportedly turning down requests.

As a result, in 1940 the development of the Mustang began, which was by itself a feat as it took only four months. Its first flight took place in October 1940. The plane was a very advanced aircraft for its time, as it had an entirely metallic airframe, while slightly bigger than the Luftwaffe’s Messerschmitt Bf-109. The P-51 featured laminar wings and a radiator located in the rear. It developed speeds of 615 km/h thanks to its Allison V-1710 engine, found in the early P-51 Mk I and P-51A Mk II. By 1942 it had joined the ranks of the RAF, with nearly 620 units issued, executing reconnaissance missions during the first landings the Allies attempted at the French port of Dieppe in August 1942, as well as ground-attack missions following poor high-altitude performance. The V-1710 tended to underperform at altitudes above 4500 meters.

As time went by, the Mustang would receive improvements that would enhance its already stellar performance. By late 1942 North American improved the propeller, the radiator and the aircraft’s aerodynamics. The developments in the engine design gave the Mustang increased horsepower and climbing ability, thus making the aircraft an exceptional air asset. The initial 12 cylinder Allison V-1710 engine was replaced with a Packard V-1650, which itself was based on the legendary Rolls Royce Merlin. As a result speed and range both were increased, with the top speed nudging up to 703 km/h and the range increasing up to 3703 km in the P-51B and C models. Furthermore, the upgrades were the key behind the Mustang’s celebrated reputation alongside its 6 12.7mm Browning machine guns. The Mustang reportedly shot down nearly 5000 enemy airplanes in air combat sorties, and destroyed nearly 4000 ground targets. Further improvements followed in the P-51D which had its airframe slightly shortened in the rear while received a revolutionary new bubble-shaped canopy. Additionally it had greater oil capacity and provisions for carrying rockets under the wings.

During the Sicily campaign the Mustang devastated the Luftwaffe and the Regia Aeronautica (Italian Air Force.) It also served as a notable escort fighter on bombing missions deep into Germany, wiping out the Luftwaffe’s defending fighters from the skies. It also had a very limited participation in the Pacific during WWII, seeing more action during the Korea War with the US Air Force, the Republic of Korea Air Force, the Royal Australian Air Force, and the South African Air Force, until all of the aforementioned replaced the Mustang with newer platforms. During the Korean conflict Mustangs were used for ground-attack and reconnaissance missions sustaining heavy losses due to ground fire. It was then in service with reserve units until 1956, except for three F-51Ds. The nomenclature for US fighters was changed from P for ‘Pursuit’ for F for ‘Fighter’ after WWII. These F-51s were used as chase planes for the Lockheed YAH-56 Cheyenne attack helicopter project and other experimental purposes until the late 60s.


The Mustang also saw extensive use in combat with other air forces. The Netherlands used them during the Indonesian War of Independence. Israel deployed the Mustang during its War of Independence and the Suez Canal Crisis also known as Operation Kadesh. The Philippines used the Mustangs for counter-insurgency purposes during the Huk campaign against communist guerrillas. Indonesia and many South American countries used the P51 in many similar campaigns against guerrilla fighters. Sweden used the Mustangs on reconnaissance versions for Operation Falun, a reconnaissance of soviet Baltic coast military installations in 1946-47; El Salvador’s Air force also made use of this model during the 1969 Soccer War against Honduras, being the last combat use between piston engine fighters (with Honduras using the Vought Chance F4U-5); and the Dominican Republic, were they took part in Operation Power Pack, an US intervention during the brief 1965 Dominican Republic Civil War. This was the last air force in withdrawing the Mustang from active duty in 1984.

The Mustang also had a civilian life after WWII and other conflicts it served. Many are now privately owned with some now in museums and on static display. Others are still airworthy and maintained by hobbyists and historical societies. Some have even been modified for racing.  A total of 15.386 Mustangs were built.


The Mustang is a low-wing fighter, with a single tail and a single engine: 1 Allison V-1710 V-12 developing 1,325 hp used in the P-51 Mk.I and P-51A Mk.II or 1 Packard V-1650 V-12 of 1,315 hp in the P-51D and onwards. Its wings featured a laminar flow airfoils that generated very low drag at high speed, also providing outstanding aerodynamic characteristics. The radiator is a remarkable feature of the Mustang, in both its shape and performance as it takes advantage of the ‘Meredith effect’ which creates a slight jet thrust from the heated air flowing outward providing more propulsion to the engine and increasing the speed of the aircraft. A 2 stage supercharger gave the Mustang power enough to outperform its German counterparts. This designs also had incidence with the length of the aircraft, which allowing the fitting of a bigger inner fuel oil tank that increased its maximum range and speed. The fuselage shares the same features as the Lansen, which was lofted mathematically using conic sections. This resulted in a smooth fuselage with low drag surfaces. The Mustang had another unique feature: its fuselage was divided into 5 sections – forward, center, rear fuselage, and two wing halves which made assembly during production very efficient.

The aircraft material was covered in aluminum overall, which made the Mustang a lightweight aircraft for its day. Combined with its aerodynamic characteristics, it was an aircraft easy to fly with good performance in-flight and during combat.

The first versions of the Mustang (P-51 to P-51C) had conventional canopy setup with the door opening and closing upwards and downwards to the side albeit possessing poor rearward visibility. The P-51D and the following versions introduced the bubble-shaped canopy that is widely known which gave the pilot a full 360° view. This design slid on rails that moved backwards, making easy entry and exit. This would influence the design of future fighters and light bombers canopies alongside its bullet-proof windscreen.

Earlier versions were armed with 4 X 12.7mm / .50 caliber AN/M2 Browning machine guns. As North American decided to upgrade the firepower, the P-51D through H versions received 6 Browning guns.

A Reliable “Little Friend” 

Mustang Bomber Escort

The Mustang would go on to win the skies and the hearts of the bombers crews, as it provided good escort to the very risky and dangerous long-range bombings deep into German territory. Needless to say, it also won the respect and fear of its adversaries. The crew of the bombers dubbed the Mustangs as “little friends” for the invaluable protection they afforded to the bombers during the deep raid missions over German-controlled skies.

The P-51 Mustang came about initially by request from the RAF to be provided with a fighter capable enough to match the German Messerschmitt, but it had the P-40 in mind. North American, the manufacturing company, proposed instead a new airplane. When it came in service with the RAF, it became the first fighter capable of penetrating deep into the German skies from England. As a result, the US decided to operate it over the skies of Italy and Sicily. Evaluating the performance and range, the P-51 was then used as bomber escort plane, being capable of reaching even Poland and Czech Republic. When executing this particular task, it became an important air asset for the Allies to control the skies of Europe. But it was not mere realization about such need what brought the P-51 into the scene. In fact, there were two factors that pushed the Allies into adopting the Mustang as escort airplane: First, the initially reluctant allies were able to assess the potential the Mustang had once the D type was introduced with all of its improvements. Second, two disastrous raids over the German city of Schweinfurt, where the bombers suffered heavy casualties at 59 destroyed, morale was low. The resulting evaluation showcased the need for bombers to be provided with escort fighters to carry out strategic bombing operations with minimal losses.

The Mustang also executed the similar escort missions in the Pacific theatre alongside the Boeing B-29 Superfortress bombers over Japan. Once the island of Iwo Jima was taken by the Marines, the Americans had a base from which both bombers and escort fighters could strike mainland Japan.


  • NA.73X – The only prototype of the Mustang, which was ready only four months after contracts were signed

  • Commonwealth CA-17 Mustang Mk 20 – The Royal Australian Air Force (RAAF) was in need of new fighters and high-altitude interceptors. An agreement between the RAAF and North American resulted in the Australian Commonwealth Aircraft Corporation (CAC) allowed to build the P-51D version under license. Powered by the Merlin engine. 100 unassembled P-51D were issued, with only 80 being fully completed by CAC (CA-17 Mk 20).
  • Commonwealth CA-18 Mustang Mk 21, Mk 22 and Mk 23 – These versions were licensed built versions by CAC. The Mk 21 was powered by a Merlin V-1650-7, the Mk23 was powered with Rolls Royce Merlin engines. The Mk22 was modified to be a reconnaissance version similar to the F-6D. 120 CA-18 were built.
  • Mustang Cavaliers (or Mustang II F-51/Mustang III-Piper PA-48 Enforcer) – Surplus P-51Ds that were modified, with all the military equipment initially removed, and a second seat added. Some received increased fuel capacity with wing tip tanks, upgraded avionics and a tall tail. Some F-51 were repaired and upgraded by Cavalier, being delivered to the Dominican Air Force (36), to the Salvadorian Air Force (9), to the Indonesian Air Force (6), and two to the US Army serving as chase planes for the Cheyenne AH-54 attack helicopter program. Attempts to keep the P-51 in service by adding a turboprop (Rolls Royce Dart) were made, resulting in the Mustang III, but they came to no avail. The project was sold to Piper, which developed the Piper PA-48 Enforcer, finding the same fate. Only two PA-48 Enforcers exist as museum pieces.
  • P-82/F-82 Twin Mustang  Designed as a long-range, high-altitude bomber escort, with a high maximum range (3600 km/2300 miles) and very high ceiling 12192m (40,000 ft), being able to escort the B-29 bombers over Japan. It had two elongated P-51 fuselages (hence its name) that gave the aforementioned characteristics, having two pilots as crew, with one later on operating a radar. The power plants were the same of the P-51D, reaching speeds of 750 km/h (500 mph). Its firepower was the same 12,7mm machineguns, placed at the central wing, 25 air-to-ground rockets or up to 4000 lbs of bombs. It saw action in the early Cold War protecting US mainland against soviet bombers, and during the earlier stages of the Korean War, as night-fighters and ground attackers.


  • United States of America – The US Air Corps/Air Force became the second and the main operator of the P-51. As the US needed a capable bomber escort, the P-51 became the choice for this purpose with the P-38 and P-47 for the initial stages of the bombing operations. The Mustang became the mostly used escort fighter in Europe by the US. When the Mustang was used in advanced formations to the bombers, fighting the German fighters before they were able to strike the bombers, it achieved air superiority. After the Luftwaffe was nearly wiped out, it performed ground-attack mission. It was on this sort of missions that the Mustang was able to destroy the German-introduced Messerschmitt 262. The top ace using Mustangs shot down 26 enemy airplanes. It had a secondary participation in the Pacific theatre. It lasts service with the USAF was during the Korean War, when it was re-denominated as F-51, until it came to be replaced with F-86 Sabres.
  • United Kingdom – The nation whose request gave birth to the Mustang P-51, being the very first operator in January 1942. 620 were Mustangs Mk I, 93 were Mk IA, 50 were Mustangs Mk II, 308, 944 were Mustangs Mk III, 208 were Mk IV, and 600 were MK VIA. The RAF used the P-51 initially as close cooperation, ground-attack and reconnaissance, due to earlier models poor performance at high altitude. Mostly returned to the US or scrapped, remained in service with the RAF until 1947.
  • Australia – Became an operator of the P-51 in 1944, although operated the Mustangs under RAF badge. It received its first P-51 in Italy, in 1944. Received 80 and 120 later on as CA-17 and CA-18, respectively. It was deployed in the Pacific, as part of the occupation force in Japan and in the Korean War. The Citizens Air Force (CAF)reserve units used the P-51s until 1960.
  • Netherlands (East Indies Air Force) – The Netherlands used the P-51 on its East Indies Air Force, receiving 40 P-51D, using them during the Indonesian War of Independence. After the war, it handed some Mustangs to the nascent Indonesian Air Force.
  • New Zealand – Ordered 370 P-51 but received only 30 P-51D when the war came to an end. The delivered Mustangs were stored in their packing cases until 1951, when they were assembled and assigned to 4 squadrons of the Territorial Air Force. Remained in service until 1955 following corrosion problems in the undercarriage and coolant system. Some P-51s were flown as loaned airplanes with the RAF, and even some flew with the USAAC.
  • Sweden – The Flygvapnet operated initially 4 P-51s (2 P-51B and 2 P-51D) that were diverted to Sweden during operations. 50 additional P-51D were purchased, later on 111 being acquired, forming two wings. 12 were modified for photo reconnaissance, being designated as S 26 and taking part in Operation Falun, Sweden’s operation in mapping the new Soviet military installations in the Baltic countries in 1946-47. Replaced by the S 29C Tunnan in the early 50’s, selling some 25 P-51 to Israel and some Latin American countries.
  • Switzerland – The Schweizer Luftwaffe operated 100 P-51 that were diverted to Switzerland during operations, purchasing additional 130 P-51. They were in service until 1958
  • Israel – Around 4 P-51 were obtained by Israel in 1948 by buying surplus scrapped airframes, assembling and disassembling them again, packing and smuggling them to Israel in crates labelled as irrigation equipment, using them during the Israeli Independence War. They also were used as reprisal-attack aircraft, protection of an Israeli Navy Ship that ran aground, latter destroying it, and reconnaissance operations. Received 25 further P-51 from Sweden in 1951. They took part in the Operation Kadesh during the Suez Crisis, and even disrupted communications of Egypt during a parachute drop at Mitla Pass. In service until 1957.
  • Italy – Italy operated 173 P-51s after the war, with fighter, training, experimental and acrobatic purposes. Had to fly with some restrictions due to some factors affecting flight.
