North American P-51 Mustang

History of the North American P-51 Mustang

The North American P-51 Mustang proved to be a valuable addition to the Allied cause during the second half of World War II. The design and test flight of the system took only a few months, and its impact was so great that it could clearly be considered a winning design for the Allies. The Mustang primarily assisted escort bombers in long-range sorties, but was capable of bombing and machine-gunning ground targets and outperformed all German fighters compared to it.

Exuding a true "classic warbird", the Mustang became one of the most iconic piston-engine fighter jets of all time.

Development

The RAF's demand for more Curtiss P-40 production fighters prompted them to consider North American aviation's manufacturing capabilities. North American designers Edgar Schmued and Raymond Rice saw this as an opportunity to launch an all-new fighter jet, and they seized the moment and created a design for UK review.

The design was accepted under new specifications in 1940, which required heavily armed fighter jets with comparable speed and the ability to operate at high altitudes - all of which required flying prototypes within a 120-day window. Development ensued, inevitably producing the NA-73X prototype within the allotted time frame (some sources say the plane was completed in just 102 days, while others say it took as long as 117 days).

The NA-73X took to the air on October 26, 1940, with its 1,100-horsepower Allison V-1710-F3R (V-1710-39) inline engine, and demonstrated its enormous potential. The design was accepted by the British as a "Mustang" and became the first production model of the 320 Mustang I.

The Mustang I was first flown by a British pilot on 1 May 1941 - these were powered by 1,100 hp Allison V-1710-39 inline engines. As tactical reconnaissance platforms, these aircraft are armed with 4 x .50 caliber heavy machine guns. The guy showed good reflexes, and its low-level performance was exemplary, surpassing even the legendary Spitfire Mark V. Although the design proved very functional, it was soon found that the performance of the system degraded significantly at altitudes above 15,000 feet. As a result, cooperative squadrons of the British Army were assigned to this type and used for low-altitude reconnaissance and high-speed ground attack, the former being their primary function. The first Mustang I mission took place with 26th Squadron on May 10, 1942.

The Mustangs successfully bombed the hangars at Berk-sur-Mer, a German-held French territory. As more and more Mustangs appeared, by the end of 1942 the aircraft was deployed with a total of about 14 Allied squadrons - 10 RAF, 3 Royal Canadian Air Force and 1 Polish Air Group. Most early production Mustangs were the Mustang Mk.

IA (4 x 20mm gun) and Mustang Mk. II models, for a total of about 620 combined examples.

Production of all 15,469 Mustangs completed in 1946. With the creation of the USAF in 1948, all remaining P-51 Mustangs in US service are now F-51s - the "P" for "Pursuit" was replaced by the "F" for "Fighter".

The F-51 sits in the newly discovered Air Force division, although the type is slowly being relegated to the role of supporting the new jets arriving on the scene. In 1967, the Mustang went into limited production, creating a variant of the turboprop for the Counterinsurgency.

Design

Despite the traditional modern approach to design, the P-51 Mustang develops a unique look when it is finished with the classic P-51D model. Early forms of Mustang had a "razor" type hull behind the cockpit. Combine that with a framed canopy, and you can imagine a somewhat obstructed view from the cockpit, especially when looking back.

Of course, the introduction of the Bubble Canopy changed all that, but also slightly shortened the body to compensate.

Overall, the design of the P-51 is clean and sleek thanks to the choice of inline engines. The pilot sits at the center of the design, just above and behind the low-wing, straight-wing layout. Pronounced air intakes are located at the rear and below the Pilot, giving the Mustang line a unique look while eliminating drag. All wing edges are relatively straight cuts, a design philosophy that runs through the horizontal and vertical edges of the rear wing.

The wings themselves feature a new advanced laminar flow design and accommodate powerful heavy weapons. Inside, engine coolant components are strategically placed directly below and behind the pilot's seat, a departure from traditional aircraft design philosophies.

The landing gear is modern, with twin monowheel main gear embedded in the wing root/lower fuselage and a retractable tail wheel.

Armed

Weaponry varies throughout the life of the Mustang. The first version was armed with 6 x .50 heavy machine guns - two in the nose and four in the wings. A 4 x 20mm gun battery makes it ideal for ground attack roles, or a lighter alternative to the 4 x .50 caliber heavy machine guns (two per wing) for tactical reconnaissance. Finally, the legendary D model introduced a powerful line of 6 x .50 caliber heavy machine guns (three per wing) with a simplified feed mechanism to reduce weapon interference.

Underwing bomb racks and missile pylons also increase the efficiency of the platform. These may be dropped in favor of fuel tanks to improve the range of those long-range bomber escort outings.

Cockpit

The cockpit of the P-51 is considered suitable for small pilots and is generally ergonomically designed. Some American pilots found their European-style origins obvious, as their shoulders could touch both sides of the cockpit at the same time.

The dashboard is considered well thought out, with all the important gauges clearly visible on the large flat main panel. The K-14A (starting with the D model) occupies a large portion of the upper-forward field of view, with its prominent "No Handheld" message staring at the pilot.

The control column is a simple cylindrical shape with a pistol grip on top, adorned with a red pistol button. The flap levers are activated from the low setting in the range. The throttle control is a thick cylinder that is naturally located on the pilot's left side, leaving his right hand free to focus on the aircraft's control column. The fuel controls are mounted between the pilot's legs, just in front of the control column. Forward, sideways and overhead visibility was generally good with the original framed canopy, but with the addition of the teardrop canopy, visibility has improved significantly.

Overall, the focus on the P-51's cockpit design makes it an ideal fighter for long-range escort missions. Its tight fit ensures a perfect fusion of man and machine.

Operating Services

In their first operation, A-36As attacked targets on the Mediterranean island of Pantelleria. The aircraft were called upon to conduct a variety of engagements, including strafing, bomber escorts and bombing raids.

Despite their low-altitude efficiency, the new Republic P-47 Thunderbolt and the updated P-51 Mustang eventually replaced the A-36 line in this role, thanks to the addition of underwing bomb carriers, impressive machine gun fire and better low altitude performance.

Mustangs were used in ground attack and escort operations when deployed by the RAF. Mustangs can now escort attack aircraft into German-held areas and support low-altitude attacks by stopping German fighter jets. Their actions against German anti-ship groups in Norway ended up taking a toll on enemy forces and opening up the Allied waterways for another day.

At least 31 RAF (Royal Air Force) and RCAF (Royal Canadian Air Force) squadrons are dedicated to the Mustang aircraft.

Unescorted daytime bombing raids deep into German-held territory had disastrous consequences for U.S. USAAF war planners. Knowing the approximate ranges of the Republic P-47 Thunderbolt and Lockheed P-38 Lightning escort fighters???, the German interceptors simply waited for the planes to return home to refuel, leaving the bomber formation to the pesky German Messerschmitt BF-109 and Focke-Wulf Fw - 190 Hunters.

Bomber formations tried to adapt, flying special "box" formations to bring their machine gun arcs to the more efficient Bears, but casualties continued to mount so that daytime bombing had to be suspended for a while.

The arrival of the Mustang, with its speed, firepower and most importantly range, soon brought the element of sun-bombing back to the fore. The introduction of drop tanks improved the fuel and range of these small aircraft, allowing them to reach distances beyond Berlin (drop tanks inevitably improved the range of all other American escort fighters). The introduction of the P-51 will inevitably have an impact on the war, especially on the D model, which cannot be underestimated. The plane almost single-handedly changed the course of war in Europeat least in the air.

The most capable German aircraft produced in any number is the Fw 190, which famous American pilot Chuck Yeager himself admitted was the P-51's closest competitor, but not quite.

Following a variant of the P-51D, the aircraft made its European theater debut in early 1944. Immediately, the Model D was used as a bomber escort, fighter-bomber and reconnaissance platform wherever they could be deployed.

The P-51D Mustang took over the aerial playing field, creating a one-sided advantage over contemporary German manufacturers. The air war situation in Europe has officially turned, and the end of the German Third Reich is just around the corner.

Following the success of the Model D in Europe, the P-51D finally entered the Pacific and Southeast theaters in late 1944. The P-51's primary mission in the Pacific was to escort the new, high-flying, long-range B-29 Superfortress on its way to and from Japan.

Mustangs fought on all fronts until the war ended in 1945.

Troubles in the Dutch East Indies in 1946 forced the Dutch to finally move out of their colonies, leaving the P-51D and P-51K models to the Indonesian Air Force. Incredibly, these Mustangs remained in service until the 1970s.

Israel angrily used Mustangs in the 1948 War of Independence and later in the 1956 Arab-Israeli War, becoming another post-war fighter.

The Korean War led to a conflict in the aviation age, as the jet age invaded the aviation world once dominated by piston-engine aircraft. Like other World War II-era airframes, the current "F-51" Mustang was put into combat combinations and intended to serve in the early and mid-term of the conflict until it was largely replaced by more powerful jets. Despite their age, their proven ground-attack efficiency and long-range capabilities have made Mustangs the component of choice for inland strikes -- a must for newer fuel-guzzling jet fighters like the Lockheed P-80 Meteor. is an unreachable position. The Mustang, which served in Australia, South Africa, and South Korea, all played a role early on, even getting multiple air-to-air kills in the process.

With the arrival of the powerful F-86 Sabre jetsespecially the F-86F fighter-bomber in 1953the Mustang's role in the war was all but over. The F-82 Twin Mustang continued to serve as an equally important night fighter and all-weather attacker on the peninsula, and is considered the USAF's first aerial victory of the war (Yakovlev Yak-9).

The American F-51 Mustang continued to fly with the Air National Guard and Air Force Reserve until fully retired in 1957. Thankfully, the plane remains a prize for aviation collectors and remains a favorite at airshows around the world.
