As well as being economical to produce, the Mustang was a fast, well-made and highly durable aircraft. The definitive version of the single-seat fighter was powered by the Packard V-1650-3, a two-stage two-speed supercharged 12-cylinder Packard-built version of the legendary Rolls-Royce Merlin engine, and (the P-51D) were armed with six of the aircraft version of the .50 caliber (12.

In 1939, shortly after World War II began, the British government established a purchasing commission in the United States, headed by Sir Henry Self. Along with Sir Wilfrid Freeman, who, as the "Air Member for Development and Production", was given overall responsibility for RAF production and research and development in 1938, Self had sat on the (British) Air Council Sub-committee on Supply (or "Supply Committee"), and one of Self's many tasks was to organize the manufacture of American fighter aircraft for the RAF. Air Chief Marshal Sir Wilfrid Rhodes Freeman 1st Baronet, GCB, DSO, MC, RAF ( 18 July 1888 &ndash At the time the choice was very limited: none of the U. S. aircraft already flying met European standards; only the Curtiss P-40 Tomahawk came close. WikipediaWikiProject Aircraft.

Kindelberger replied that NAA could have a better aircraft with the same engine in the air in less time than it would take to set up a production line for the P-40. By now the executive head of the British Ministry of Aircraft Production (MAP), Freeman ordered 320 aircraft in March 1940. The Minister of Aircraft Production was the British government position in charge of the Ministry of Aircraft Production one of the specialised supply ministries set up by the British On 26 June 1940, MAP awarded a contract to Packard to build modified versions of the Rolls-Royce Merlin engines under licence; in September, MAP increased the first production order by 300.

The result of the MAP order was the NA-73X project (from March 1940). The design followed the best conventional practice of the era, but included two new features. One was a new NACA-designed laminar flow wing, which was associated with very low drag at high speeds. Laminar flow, sometimes known as streamline flow occurs when a fluid flows in parallel layers with no disruption between the layers [4] Another was the use of a new radiator design (one Curtiss had been unable to make work) that used the heated air exiting the radiator as a form of jet thrust in what is referred to as the "Meredith Effect". A jet aircraft is an Aircraft propelled by Jet engines Jet aircraft fly much faster than Propeller -powered aircraft and at higher altitudes -- as high as Because North American lacked a suitable wind tunnel, it used the GALCIT 10-foot wind tunnel at Cal Tech. This led to some controversy over whether the Mustang's cooling system aerodynamics were developed by North American's engineer Edgar Schmued or by Curtiss, although historians and researchers dismiss the allegation of stolen technology; such claims are likely moot in any event, as North American had purchased Curtiss’ complete set of P-40 and XP-46 wind tunnel data and flight test reports for US$56,000.

While the United States Army Air Corps could block any sales it considered detrimental or not in the interest of the United States, the NA-73 represented a special case. The United States Army Air Corps (USAAC was the predecessor of the U In order to ensure deliveries were uninterrupted, an arrangement was eventually reached where the RAF would get its aircraft in exchange for NAA providing two free examples to the USAAC for evaluation.
The prototype NA-73X was rolled out just 117 days after the order was placed, and first flew on 26 October 1940, just 178 days after the order had been placed — an incredibly short gestation period. Events 740 - An Earthquake strikes Constantinople, causing much damage and death Year 1940 ( MCMXL) was a Leap year starting on Monday (link will display the full 1940 calendar of the Gregorian calendar.

It was quickly evident that performance, although exceptional up to 15,000 feet, was markedly reduced at higher altitudes. This deficiency was due largely to the single speed, single stage supercharger of the Allison V-1710 engine, where power diminished rapidly above the critical altitude rating. A supercharger is an air compressor used for Forced induction of an Internal combustion engine. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout Prior to the Mustang project, the USAAC had Allison concentrate primarily on turbochargers in concert with General Electric; these proved to be exceptional in the P-38 Lightning and other high-altitude aircraft, in particular, the Air Corp's four-engine bombers. A turbocharger, or turbo, is an air Compressor used for forced-induction of an Internal combustion engine. Most of the other uses for the Allison were for low-altitude designs, where a simpler supercharger would suffice. The turbocharger proved impractical in the Mustang, and it was forced to use the inadequate supercharger available. Still, the Mustang's advanced aerodynamics showed to advantage, as the Mustang I was about 30 mph faster than contemporary Curtiss P-40 fighters, using the same powerplant. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The Mustang I was 30 mph faster than the Spitfire Mk VC at 5,000 ft and 35 mph faster at 15,000 ft, despite the British aircraft's more powerful engine.

The first production contract was awarded by the British for 320 NA-73 fighters, named Mustang I by the British. Two aircraft of this lot delivered to the USAAC for evaluation were designated XP-51. [7] About 20 Mustang Is were delivered to the RAF, making their combat debut on 10 May 1942. Events 1291 - Scottish Nobles recognize the authority of Edward I of England. Year 1942 ( MCMXLII) was a Common year starting on Thursday (the link will display the full 1942 calendar of the Gregorian calendar. With their long range and excellent low-level performance, they were employed effectively for tactical reconnaissance and ground-attack duties over the English Channel, but were thought to be of limited value as fighters due to their poor performance above 15,000 ft.
A second British contract called for 300 more (NA-83) Mustang I fighters. In September 1940, 150 aircraft, designated NA-91 by North American, were ordered under the Lend/Lease program. These were designated by the USAAF as P-51 and initially named Apache, although this was soon dropped and the RAF name, Mustang, adopted instead. The British designated this model as Mustang IA. The Mustang Mk IA was identical to the Mustang Mk I except that the wing-mounted machine guns were removed and replaced with four long-barrelled 20 mm Hispano Mk II cannon. The Hispano-Suiza HS404 Autocannon was one of the most widely used aircraft weapons of the 20th century used by British, American
A number of aircraft from this lot were fitted out by the USAAF as F-6A photoreconnaissance aircraft. The British would fit a number of Mustang Is with similar equipment. Also, two aircraft of this lot were fitted with Packard-built Merlin engines mounted behind the cockpit, in the fashion of the P-39. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout [8] This was identified as Model NA-101 by North American and XP-78 by the USAAF, later redesignated XP-51B.
At the same time, the USAAC was becoming more interested in ground attack aircraft and had a new version ordered as the A-36 Apache, which included six . WikipediaWikiProject Aircraft.

In early 1942, the USAAF ordered 500 aircraft modified as dive bombers that were designated A-36A (NA-97). This model became the first USAAF Mustang to see combat. One aircraft was passed to the British who gave it the name Mustang I (Dive Bomber).
In April 1942, the RAF's Air Fighting Development Unit (AFDU) tested the Mustang and found its performance inadequate at higher altitudes. As such it was to be used to replace the Tomahawk in Army Cooperation Command squadrons but the commanding officer was so impressed with its maneuverability and low-altitude speeds that he invited Ronnie Harker from Rolls Royce's Flight Test establishment to fly it. For the present day company see Rolls-Royce plc. For other uses see Rolls-Royce (disambiguation. Rolls-Royce engineers rapidly realized that equipping the Mustang with a Merlin 61 engine with its two speed, two stage supercharger would substantially improve performance and started converting five aircraft as the Mustang X. The North American Mustang X (sometimes known as the " Rolls-Royce Mustang " was a variant of the P-51 Mustang utilizing a Rolls-Royce The Vice-Chief of the Air Staff, Air Marshal Sir Wilfrid R. Freeman, lobbied vociferously for Merlin-powered Mustangs, insisting two of the five experimental Mustang Xs be handed over to Carl Spaatz for trials and evaluation by the U. Air Chief Marshal Sir Wilfrid Rhodes Freeman 1st Baronet, GCB, DSO, MC, RAF ( 18 July 1888 &ndash Carl Andrew "Tooey" Spaatz GBE (June 28 1891 &ndash July 14 1974 was an American general in World War II, and the first Chief of S. 8th Air Force in Britain. [9]
The high-altitude performance improvement was astonishing: the Mustang X (AM208) reached 433 mph (697 km/h) at 22,000 ft and AL975 tested at an absolute ceiling of 40,600 ft. In the United Kingdom to identify individual aircraft all military aircraft are allocated and display a Serial number. [10]After sustained lobbying at the highest level, American production of a North American-designed Mustang, with the Packard Merlin V-1650 engine replacing the Allison, was started in early 1943. The pairing of the P-51 airframe and Merlin engine was designated P-51B or P-51C, B (NA-102) being manufactured at Inglewood, California, and C (NA-103) at a new plant in Dallas, Texas, in operation by summer 1943. The RAF named these models Mustang III. In performance tests, the P-51B reached 441 mph/709. 70 km/h (exactly two-thirds supersonic speed at altitude) at 25,000 ft (7. 600 m) and the subsequent extended range made possible by the use of drop tanks enabled the Merlin-powered Mustang to be introduced as a bomber escort.
P-51Bs and Cs started to arrive in England in August and October 1943. The P-51B/C versions were sent to 15 fighter groups that were part of the 8th and 9th Air Forces in England, and the 12th and 15th in Italy (the southern part of Italy was under Allied control by late 1943).

China Burma India Theater (CBI (later IBT or India-Burma theater was the name used by the United States Army for its forces operating in conjuction with Allied air
Allied strategists quickly exploited the long-range fighter as a bomber escort. It was largely due to the P-51 that daylight bombing raids deep into German territory became possible without prohibitive bomber losses in late 1943.
A number of the P-51B and P-51C aircraft were fitted for photo reconnaissance and designated F-6C.
One of the few remaining complaints with the Merlin-powered aircraft was a poor rearward view. This was a common problem in most fighter designs of the era, which had only been recognized by the British after the Battle of Britain proved the value of an all-around view. The Battle of Britain (German ''Luftschlacht um England'' is the name given to the sustained strategic effort by the German Luftwaffe during the summer and In order to improve the view from the Mustang at least partially, the British had field-modified some Mustangs with fishbowl-shaped canopies called "Malcolm Hoods. An aircraft canopy is the transparent enclosure over the cockpit of some types of Aircraft. " Eventually all Mk IIIs, along with some American P-51B/Cs, were equipped with Malcolm Hoods.
A better solution to the problem was the "teardrop" or "bubble" canopy. Originally developed as part of the Miles M.20 project, these newer canopies were in the process of being adapted to most British designs, eventually appearing on late-model Spitfires, Typhoons and Tempests. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout North American adapted several NA-106 prototypes with a bubble canopy, cutting away the decking behind the cockpit, resulting in substantially improved vision to the rear. A bubble canopy is a canopy made like a soap Bubble, which attempts to provide 360° vision to the pilot This led to the production P-51D (NA-109), considered the definitive Mustang.
A common misconception is that the cutting down of the rear fuselage to mount the bubble canopy reduced stability that required the addition of a dorsal fin to the forward base of the vertical tail. Actually, both earlier Bs and Cs and subsequent D/K models also experienced low speed handling problems that could result in an involuntary "snap-roll" under certain conditions of air speed, angle of attack, gross weight and center of gravity. Several crash reports tell of P-51Bs and Cs crashing because horizontal stabilizers were torn off during maneuvering. One report stated:
"Unless a dorsal fin is installed on the P-51B, P-51C and P-51D airplanes, a snap roll may result when attempting a slow roll. The horizontal stabilizer will not withstand the effects of a snap roll. To prevent recurrence the stabilizer should be reinforced in accordance with T. O. 01-60J-18 dated 8 April 1944 and a dorsal fin should be installed. Events 217 - Roman Emperor Caracalla is Assassinated (and succeeded by his Praetorian Year 1944 ( MCMXLIV) was a Leap year starting on Saturday (link will display full calendar of the Gregorian calendar. Dorsal fin kits are being made available to overseas activities"
While some existing aircraft do not have the dorsal extension fitted, many were equipped at some point in their service or refurbishment with a taller tail, which provided a similar increase in yaw stability. Also, civilian-owned examples often have newer, lighter radios, an absence of external munitions and drop tanks, removed guns and armor plate and an empty or removed fuselage tank — reducing the need for the dorsal fin.
Among other modifications, armament was increased with the addition of another two M2 machine guns, bringing the total to six. This article is about the.50 caliber M2 machine gun For the.30-06 M2 machine gun see M1919 Browning machine gun. The inner pair of machine guns had 400 rounds each, and the others had 270 rounds, for a total of 1,880. In previous P-51s, the M2s were mounted at angles that led to frequent complaints of jamming during combat maneuvers. The new arrangement allowed the M2s to be mounted in a more standard manner that remedied most of the jamming problems. The . 50 caliber Browning machine guns, although not firing an explosive projectile, had excellent ballistics and proved adequate against the Fw 190 and Bf 109 fighters that were the main USAAF opponents at the time.

Please see WikipediaWikiProject Aircraft/page content for recommended layout Later models had under-wing rocket pylons added to carry up to ten rockets per plane.
The P-51D became the most widely produced variant of the Mustang. A Dallas-built version of the P-51D, designated the P-51K, was equipped with an Aeroproducts propeller in place of the Hamilton Standard propeller, as well as a larger, differently configured canopy and other minor alterations (the vent panel was different). Hamilton Standard, a famous Aircraft Propeller parts supplier was formed in 1929 when United Aircraft & Transport Corporation consolidated Hamilton Aero Manufacturing The hollow-bladed Aeroproducts propeller was unreliable with dangerous vibrations at full throttle due to manufacturing problems and was eventually replaced by the Hamilton Standard. By the time of the Korean war most F-51s were equipped with "uncuffed" Hamilton Standard propellers with wider, blunt tipped blades. Hamilton Standard, a famous Aircraft Propeller parts supplier was formed in 1929 when United Aircraft & Transport Corporation consolidated Hamilton Aero Manufacturing The photo reconnaissance versions of the P-51D and P-51K were designated F-6D and F-6K respectively. The RAF assigned the name Mustang IV to the D model and Mustang IVA to K models.
The P-51D/K started arriving in Europe in mid-1944 and quickly became the primary USAAF fighter in the theater. It was produced in larger numbers than any other Mustang variant. Nevertheless, by the end of the war, roughly half of all operational Mustangs were still B or C models.
Concern over the USAAF's inability to escort B-29s all the way to mainland Japan resulted in the highly classified "Seahorse" project. In late 1944 Naval Aviator (and later test pilot) Bob Elder flew carrier suitability trials with a modified P-51D. The project was canceled after U. S. Marines secured the Japanese island of Iwo Jima and its airfields, making it possible for standard P-51D models to accompany B-29s all the way to the Japanese home islands and back. ("Fly Navy" - Phil Kaplan, page 51)
During 1945–48, P-51Ds were also built under licence in Australia by the Commonwealth Aircraft Corporation (see below). For a topic outline on this subject see List of basic Australia topics. The Commonwealth Aircraft Corporation (CAC was an Australian aircraft manufacturer
The USAAF required airframes built to their acceleration standard of 8. 33 g (82 m/s²), a higher load factor than that used by the British standard of 5. 33 g (52 m/s²) for their fighters. Reducing the load factor to 5. 33 would allow weight to be removed, and both the USAAF and the RAF were interested in the potential performance boost.
A subtle change made in the lightweight Mustangs was the use of an improved NACA 66 series airfoil and a slightly thinner wing than that used by earlier Mustangs. [11]
In 1943, North American submitted a proposal to re-design the P-51D as model NA-105, which was accepted by the USAAF. Modifications included changes to the cowling, a simplified undercarriage with smaller wheels and disc brakes, and a larger canopy. The designation XP-51F was assigned to prototypes powered with V-1650 engines (a small number of XP-51Fs were passed to the British as the Mustang V) and XP-51G to those with reverse lend/lease Merlin 145M engines. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout
A third lightweight prototype powered by an Allison V-1710-119 engine was added to the development program. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout This aircraft was designated XP-51J. Since the engine was insufficiently developed, the XP-51J was loaned to Allison for engine development. None of these experimental "lightweights" went into production.
The P-51H (NA-126) was the final production Mustang, embodying the experience gained in the development of the XP-51F and XP-51G aircraft. This aircraft, with minor differences as the NA-129, came too late to participate in World War II, but it brought the development of the Mustang to a peak as one of the fastest production piston engine fighters to see service.
The P-51H used the new V-1650-9 engine, a version of the Merlin that included Simmons automatic supercharger boost control with water injection, allowing War Emergency Power as high as 2218 hp (1,500 kW). WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout Differences between the P-51D included lengthening the fuselage and increasing the height of the tailfin, which greatly reduced the tendency to yaw. The canopy resembled the P-51D style, over a somewhat raised pilot's position. Service access to the guns and ammunition was also improved. With the new airframe several hundred pounds lighter, the extra power and a more streamlined radiator, the P-51H was among the fastest propeller fighters ever, able to reach 487 mph (784 km/h or Mach 0. Mach number (\mathrm{Ma} or M (generally ˈmɑːk sometimes /ˈmɑːx/ or /ˈmæk/ is the speed of an object moving through air or any Fluid 74) at 25,000 ft (7,600 m).
The P-51H was designed to complement the P-47N as the primary aircraft for the invasion of Japan with 2,000 ordered to be manufactured at Inglewood. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout For a topic outline on this subject see List of basic Japan topics. Production was just ramping up with 555 delivered when the war ended. Production serial numbers:
Additional orders, already on the books, were cancelled. With the cutback in production, the variants of the P-51H with different versions of the Merlin engine were produced in either limited numbers or terminated. These included the P-51L, similar to the P-51H but utilizing the 2270 horsepower V-1650-11 Merlin engine, which was never built; and its Dallas-built version, the P-51M or NA-124 which utilized the V-1650-9A Merlin engine lacking water injection and therefore rated for lower maximum power, of which one was built out of the original 1629 ordered, serial number 45-11743.
Although some P-51Hs were issued to operational units, none saw combat in World War II, and in postwar service, most were issued to reserve units. One aircraft was provided to the RAF for testing and evaluation. Serial number 44-64192 was designated BuNo 09064 and used by the U. S. Navy to test transonic airfoil designs, then returned to the Air National Guard in 1952. Transonic is an Aeronautics term referring to a range of velocities just below and above the Speed of sound (about mach 0 The P-51H was not used for combat in the Korean War despite its improved handling characteristics, since the P-51D was available in much larger numbers and was a proven commodity. The Korean War refers to a period of military conflict between North Korean and South Korean regimes with major hostilities lasting from June 25 1950 until the
Many of the aerodynamic advances of the P-51 (including the laminar flow wing) were carried over to North American's next generation of jet-powered fighters, the Navy FJ Fury and Air Force F-86 Sabre.

At the Casablanca Conference, the Allies formulated the Combined Bomber Offensive (CBO) plan for "round-the-clock" bombing by the RAF at night and the USAAF by day. The Casablanca Conference (codenamed SYMBOL was held at the Anfa Hotel in Casablanca, Morocco, then a French Protectorate, from January 14 to Operation Pointblank was the code name for the Combined Bomber Offensive of the USAAF and the RAF during World War II. American pre-war bombardment doctrine held that large formations of heavy bombers flying at high altitudes would be able to defend themselves against enemy interceptors with minimal fighter escort, so that precision daylight bombing using the Norden bombsight would be effective. The Norden bombsight was a Bombsight used by the United States Army Air Forces during World War II, and the United States Air Force in the
Both the RAF and Luftwaffe had attempted daylight bombing and discontinued it, believing advancements in single-engine fighters made multi-engined bombers too vulnerable, contrary to Giulio Douhet's thesis. General Giulio Douhet ( 30 May 1869 - 15 February 1930) was an Italian Air power theorist The RAF had worried about this in the mid-1930s and had decided to produce an all night-bomber force, but initially began bombing operations by day. The Germans used extensive daylight bombing during the Battle of Britain in preparation for a possible invasion. The Battle of Britain (German ''Luftschlacht um England'' is the name given to the sustained strategic effort by the German Luftwaffe during the summer and Due to the high casualty rates, the Luftwaffe soon switched to night bombing (see The Blitz). The Blitz was the sustained bombing of Britain by Nazi Germany between 7 September 1940 and 10 May 1941 in World War II. Bomber Command followed suit in its raids over Germany.
Initial USAAF efforts were inconclusive because of the limited scale. In June 1943, the Combined Chiefs of Staff issued the Pointblank Directive to destroy the Luftwaffe before the invasion of Europe, putting the CBO into full implementation. Operation Pointblank was the code name for the Combined Bomber Offensive of the USAAF and the RAF during World War II. The Eighth Air Force heavy bomber force conducted a series of deep penetration raids into Germany beyond the range of available escort fighters. Eighth Air Force is a Numbered Air Force (NAF of the United States Air Force Air Combat Command (ACC German fighter reaction was fierce and bomber losses were severe — 20 percent in an October 14 attack on the German ball-bearing industry.

The Lockheed P-38 Lightning had the range to escort the bombers, but was available in very limited numbers in the European theater due to its Allison engines proving difficult to maintain. The Lockheed Corporation (originally Loughead Aircraft Manufacturing Company was an American aerospace company founded in 1912 which merged with Martin Marietta With the extensive use of the P-38 in the Pacific Theater of Operations, where its twin engines were deemed vital to long-range "over-water" operations, nearly all European-based P-38 units converted to the P-51 in 1944. The Pacific Theater of Operations (PTO was the World War II military activity in the Pacific Ocean and the countries bordering it a geographic scope The Republic P-47 Thunderbolt was capable of meeting the Luftwaffe on more than even terms, but did not at the time have sufficient range. The Republic Aviation Corporation was an American aircraft manufacturer based in Farmingdale Long Island New York. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The Mustang changed all that. In general terms, the Mustang was at least as simple as other aircraft of its era. It used a single, well-understood, reliable engine, and had internal space for a huge fuel load. With external fuel tanks, it could accompany the bombers all the way to Germany and back.
Enough P-51s became available to the 8th and 9th Air Forces in the winter of 1943-44, and when the Pointblank offensive resumed in early 1944, matters changed dramatically. Ninth Air Force (Air Forces Central is a Numbered Air Force in Air Combat Command (ACC The P-51 proved perfect for the task of escorting bombers all the way to the deepest targets, thus complementing the more numerous P-47s until sufficient Mustangs became available. The Eighth Air Force immediately began to switch its fighter groups to the Mustang, first exchanging arriving P-47 groups for those of the Ninth Air Force using P-51s, then gradually converted its Thunderbolt and Lightning groups until by the end of the year 14 of its 15 groups flew the Mustang.
Luftwaffe pilots attempted to avoid U. ( German 'luftvafe is a generic German term for an Air force. S. fighters by massing in huge numbers well in front of the bombers, attacking in a single pass, then breaking off the attack, allowing escorting fighters little time to react. While not always successful in avoiding contact with escort (as the tremendous loss of German pilots in the spring of 1944 indicates), the threat of mass attacks, and later the "company front" (eight abreast) assaults by armored Sturmgruppe Fw 190s, brought an urgency to attacking the Luftwaffe wherever it could be found. The P-51, particularly with the advent of the K-14 gunsight and the development of "Clobber Colleges" for the in-theater training of fighter pilots in fall 1944, was a decisive element in Allied countermeasures against the Jagdverbände.
Beginning in late February 1944 Eighth Air Force fighter units began systematic strafing attacks on German airfields that picked up in frequency and intensity throughout the spring with the objective of gaining air supremacy over the Normandy battlefield. Normandy (Normandie Norman: Normaundie) is a geographical region corresponding to the former Duchy of Normandy. In general these were conducted by units returning from escort missions, but beginning in March many groups also were assigned airfield attacks instead of bomber support. On April 15 VIII FC began Operation Jackpot, attacks on specific Luftwaffe fighter airfields, and on May 21 these attacks were expanded to include railways, locomotives, and rolling stock used by the Germans for movements of materiel and troops in missions dubbed "Chattanooga".

Rolling Stock was a Newspaper of ideas and a chronicle of the 1980s published in Boulder, Colorado " Chattanooga Choo Choo " is a Big-band / swing song which was featured in the 1941 movie Sun Valley Serenade, which starred [12] The P-51 also excelled at this mission, although losses were much higher on strafing missions than in air-to-air combat, partially due to the vulnerability of the Mustang's cooling system to small arms hits. Like other fighters using liquid cooled engines, the Mustang's coolant system could be punctured by a hit from a single bullet.
The numerical superiority of the USAAF fighters, superb flying characteristics of the P-51 and pilot proficiency helped cripple the Luftwaffe's fighter force. The United States Army Air Forces ( USAAF) was the military aviation arm of the United States of America during and immediately after World War II. As a result, the fighter threat to US, and later British bombers, was greatly diminished by summer 1944.
P-51s also distinguished themselves against advanced enemy rockets and aircraft. A P-51B/C with high-octane fuel was fast enough to pursue the V-1s launched toward London. The Fieseler Fi 103, better known as V-1 (German Vergeltungswaffe 1 was an early Cruise missile used during World War Two London ( ˈlʌndən is the capital and largest urban area in the United Kingdom.

The Me 262 then attempted to attack the bombers, only to be cut off by a mixed formation of P-51s and P-47s. The Fighter Groups competed for the kill. Eventually a P-47 pilot of the 56th, and Mustang pilots Lt Gerbe and Groce of the 352nd Fighter Groups, shared the kill. [14]
The Eighth, Ninth and Fifteenth Air Forces' P-51 groups, all but three of which flew another type before converting to the Mustang, claimed some 4,950 aircraft shot down (about half of all USAAF claims in the European theater) and 4,131 destroyed on the ground. Losses were about 840 aircraft.
One of these groups, the Eighth Air Force's 4th Fighter Group, was the overall top-scoring fighter group in Europe with 1,016 enemy aircraft claimed destroyed. Eighth Air Force is a Numbered Air Force (NAF of the United States Air Force Air Combat Command (ACC The 4th Fighter Group was an American element of the United States Army Air Forces (USAAF Eighth Air Force during World War II, and is This included 550 claimed in aerial combat and 466 claimed on the ground. [15]
In aerial combat, the top-scoring P-51 units (both of which exclusively flew Mustangs) were the 357th Fighter Group of the Eighth Air Force with 595 air-to-air combat victories, and the Ninth Air Force's 354th Fighter Group with 701, which made it the top scoring outfit in aerial combat of all fighter groups of any type. The 357th Fighter Group was an air combat unit of the United States Army Air Forces during the Second World War. Martin Bowman reports that in the ETO Mustangs flew 213,873 sorties and lost 2,520 aircraft to all causes.
P-51s were deployed in the Far East later in 1944, operating in close-support and escort missions as well as operating in the Tactical Photo Reconnaissance role.
In the aftermath of World War II, the USAAF consolidated much of its wartime combat force and selected the P-51 as a "standard" piston engine fighter while other types such as the P-38 and P-47 were withdrawn or given substantially reduced roles. However, as more advanced jet fighters (P-80 and P-84) were being introduced, the P-51 was relegated to secondary status.
In 1947, the newly-formed USAF Strategic Air Command employed Mustangs alongside F-6 Mustangs and F-82 Twin Mustangs, due to their range capabilities. The Strategic Air Command (SAC was both a major command and a "specified command" in the U In 1948, the designation P-51 (P for pursuit) was changed to F-51 (F for fighter) and the existing F designator for photographic reconnaissance aircraft was dropped because of a new designation scheme throughout the USAF. Aircraft still in service in the USAF or Air National Guard (ANG) when the system was changed included: F-51B, F-51D, F-51K, RF-51D (formerly F-6D), RF-51K (formerly F-6K), and TRF-51D (two-seat trainer conversions of F-6Ds). They remained in service from 1946 through 1951. By 1950, although Mustangs continued in service with the USAF and many other nations after the war, the majority of the USAF's Mustangs had been surplussed or transferred to the Reserve and the Air National Guard (ANG).
During the Korean War, F-51s, though obsolete as fighters, were used as tactical bombers and reconnaissance aircraft. The Korean War refers to a period of military conflict between North Korean and South Korean regimes with major hostilities lasting from June 25 1950 until the Because of its lighter structure and less availability of spare parts, the newer, faster F-51H was not used in Korea. With the aircraft being used for ground attack, their performance was less of a concern than their ability to carry a load.
At the start of the Korean War, the Mustang once again proved its usefulness. The Korean War refers to a period of military conflict between North Korean and South Korean regimes with major hostilities lasting from June 25 1950 until the With the availability of F-51Ds in service and in storage, a substantial number were shipped via aircraft carriers to the combat zone for use initially by both the Republic of Korea Air Force (ROKAF) and USAF. The Republic of Korea Air Force ( ROK Air Force, ROKAF, Hanglul: 대한민국 공군 Hanja: 大韓民國 空軍 is the Air force Rather than employing them as interceptors or "pure" fighters, the F-51 was given the task of ground attack, fitted with rockets and bombs. After the initial invasion from North Korea, USAF units were forced to fly from bases in Japan, and F-51Ds could hit targets in Korea that short-ranged F-80 jet fighters could not. A major concern over the vulnerability of the cooling system was realized in heavy losses due to ground fire. Mustangs continued flying with USAF, Republic of Korea Air Force (ROKAF), South African Air Force (SAAF) and Royal Australian Air Force (RAAF) fighter-bomber units on close support and interdiction missions in Korea until they were largely replaced by Republic F-84 and Grumman Panther jet fighter-bombers in 1953.

F-51s flew in the USAF Reserve and Air National Guard throughout the 1950s. The last American USAF Mustang was P-51D-30-NA Serial No. 44-74936, which was finally withdrawn from service with the West Virginia ANG in 1957. This aircraft is now on display at the National Museum of the United States Air Force in Dayton, Ohio. The National Museum of the United States Air Force (formerly the United States Air Force Museum) is the official National Museum of the United States Air Dayton is a city in southwestern Ohio, United States. It is the County seat and largest city of Montgomery County. It is, however, painted as P-51D-15-NA Ser No. 44-15174. [16]
The final withdrawal of the Mustang from USAF dumped hundreds of P-51s out onto the civilian market. The rights to the Mustang design were purchased from North American by the Cavalier Aircraft Corporation, which attempted to market the surplus Mustang aircraft both in the U. Cavalier Aircraft Corporation was a Sarasota Florida aircraft manufacturing sales and maintenance company whose most famous products were refurbished P-51D Mustangs known S. and overseas. In 1967 and again in 1972, the USAF procured batches of remanufactured Mustangs from Cavalier, most of them destined for air forces in South America and Asia that were participating in the Military Assistance Program (MAP). South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a The Mutual Defense Assistance Act commonly known as the Battle Act was a 1949 law passed by the United States. These aircraft were remanufactured from existing original F-51D airframes but were fitted with new V-1650-7 engines, a new radio fit, tall F-51H-type vertical tails, and a stronger wing which could carry six 0. 50-inch machine guns and a total of eight underwing hardpoints. Two 1000-pound bombs and six five-inch rockets could be carried. They all had an original F-51D-type canopy, but carried a second seat for an observer behind the pilot. One additional Mustang was a two-seat dual-control TF-51D (67-14866) with an enlarged canopy and only four wing guns. Although these remanufactured Mustangs were intended for sale to South American and Asian nations through the Military Assistance Program (MAP), they were delivered to the USAF with full USAF markings. They were, however, allocated new serial numbers (67-14862/14866, 67-22579/22582 and 72-1526/1541). [16]
The last U. S. military use of the F-51 was in 1968, when the U. S. Army employed a vintage F-51D (44-72990) as a chase aircraft for the Lockheed YAH-56 Cheyenne armed helicopter project. The United States Army is a military organization whose primary mission is to "provide necessary forces and capabilities. WikipediaProject Aircraft. Please see WikipediaProject Aircraft/page content for recommended layout This aircraft was so successful that the Army ordered two F-51Ds from Cavalier in 1968 for use at Fort Rucker as chase planes. Fort Rucker is a US Army post located mostly in Dale County, Alabama, United States. They were assigned the serials 68-15795 and 65-15796. These F-51s had wingtip fuel tanks and were unarmed. Following the end of the Cheyenne program, these two chase aircraft were used for other projects. One of them (68-15795) was fitted with a 106-mm recoilless rifle for evaluation of the weapon's value in attacking fortified ground targets. [17]
The F-51 was adopted by many foreign air forces and continued to be an effective fighter into the mid 1980s with smaller air arms. The last Mustang ever downed in battle occurred during Operation Power Pack in the Dominican Republic in 1965, with the last aircraft finally being retired by the Dominican Air Force (FAD) in 1984. The Dominican Republic ( Spanish: República Dominicana;) is a nation located in the Caribbean region and shares the island of Hispaniola with [18]
The P-51 Mustang remained in service with more than 30 air forces after World War II; the last was retired from active service in the early 1980s. Here is a list of some of the countries that used the P-51 Mustang.
Many P-51s were sold as surplus after the war, often for as little as $1,500. RAF Bodney is a former World War II RAF Station and USAAF airfield in England. Some were sold to former wartime fliers or other aficionados for personal use, while others were modified for air racing. [29]
One of the most prominent Mustangs involved in air racing was a surplus P-51C purchased by Paul Mantz, a film stunt pilot. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The aircraft was modified by creating a "wet wing", sealing the wing to create a giant fuel tank in each wing, which eliminated the need for fuel stops or drag-inducing drop tanks. This Mustang, called "Blaze of Noon", came in first in the 1946 and 1947 Bendix Air Races, second in the 1948 Bendix and third in the 1949 Bendix. He also set a U. S. coast-to-coast record in 1947. The Mantz Mustang was sold to Charles F. Blair Jr (future husband of Maureen O'Hara) and re-named "Excaliber III". Maureen O'Hara (born Maureen FitzSimons on 17 August 1920 in Ranelagh, County Dublin, Ireland) is an Irish film actress Blair used it to set a New York-to-London record in 1951. Later that same year he flew from Norway to Fairbanks, Alaska, via the North Pole, proving that navigation via sun sights was possible over the magnetic north pole region. For this feat, he was awarded the Harmon Trophy and the Air Force was forced to change its thoughts on a possible Soviet air strike from the north. This Mustang now resides in the National Air and Space Museum at Steven F. Udvar-Hazy Center.

The most prominent firm to convert Mustangs to civilian use was Trans-Florida Aviation, later renamed Cavalier Aircraft Corporation, which produced the Cavalier Mustang. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout Modifications included a taller tailfin and wingtip tanks. A number of conversions included a Cavalier Mustang specialty: a "tight" second seat added in the space formerly occupied by the military radio and fuselage fuel tank.
Ironically, in the late 1960s and early 1970s when the United States Department of Defense wished to supply aircraft to South American countries and later Indonesia, for close air support and counter insurgency, it turned to Cavalier to return some of their civilian conversions back to updated military specifications.

In early 1942, the USAAF ordered a lot of 500 aircraft modified as dive bombers that were designated A-36A. North American assigned the aircraft the model number NA-97. This model became the first USAAF Mustang to see combat. One aircraft was passed to the British who gave it the name Mustang I (Dive Bomber).
Following the A-36A order the USAAF ordered 310 model NA-99 fighters that were designated P-51A by the USAAF. and Mustang II by the RAF. A number of this lot of aircraft were equipped with K-24 cameras and designated F-6B. All these models of the Mustang were equipped with Allison V-1710 engines except the prototype XP-51B.
Beginning with the model NA-102 Mustang the Packard built Merlin V-1650 engine replaced the Allison. In the summer of 1943 Mustang production was begun at a new plant in Dallas, Texas as well as at the existing facility in Inglewood, California. The model NA-102 was produced as the P-51B in Inglewood while the NA-103 as the P-51C was produced at Dallas. The RAF named these models Mustang III. Again, a number of the P-51B and P-51C aircraft were fitted for photo Reconnaissance and designated F-6C.
The prototypes of the bubble canopy change were designated model NA-106 by North American and P-51D by the USAAF. The production version, while retaining the P-51D designation, was assigned a model number NA-109 by North American. The "D" became the most widely produced variant of the Mustang. A variation of the P-51D equipped with an Aeroproducts propeller in place of the Hamilton Standard propeller was designated the P-51K. The photo versions of the P-51D and P-51K were designated F-6D and F-6K respectfully. The RAF assigned the name Mustang IV to the "D" model and Mustang IVA to "K" models.
As the USAAF specifications required airframe design to a higher load factor than that used by British for their fighters, consideration was given to re-designing the Mustang to the lower British requirements in order to reduce the weight of the aircraft and thus improve performance. In 1943, North American submitted a proposal to do the re-design as model NA-105, which was accepted by the USAAF. The designation XP-51F was assigned for prototypes powered with V-1650 engines and XP-51G to those with reverse lend/lease Merlin 145M engines. Modifications included changes to the cowling, a simplified undercarriage with smaller wheels and disk brakes, and a larger canopy. A third prototype was added to the development that was powered by an Allison V-1710 engine. This aircraft was designated XP-51J. As the engine was insufficiently developed the XP-51J was loaned to Allison for engine development. A small number of XP-51Fs were passed to the British as the Mustang V.
The final production Mustang, the P-51H embodied the experience gained in the development of the lightweight XP-51F and XP-51G aircraft. This aircraft, model NA-126 and with minor differences NA-129, came too late to participate in World War II, but it brought the development of the Mustang to a peak which was probably the fastest production piston engine fighter to see service. The P-51H used the Merlin V-1659-9 engine, equipped with Simmons automatic boost control and water injection, allowing War Emergency Power as high as 2,218 horsepower. Water injection, also known as anti-detonant injection, is a method for cooling the Combustion chambers of Engines by adding Water to the incoming War Emergency Power ( WEP) is an American term for the Throttle setting on some World War II military Aircraft engines For use in emergency situations Some of the weight savings inherited from the XP-51F and XP-51G were invested in lengthening the fuselage and increasing the height of the tailfin, greatly reducing the tendency to yaw, and in restoring the fuselage fuel tank. The canopy was changed back to more nearly resemble the P-51D style, over a somewhat raised pilot's position. Service access to the guns and ammunition was improved. The P-51H was designed to complement the P-47N as the primary aircraft for the invasion of Japan and 2,000 were ordered to be built at the Inglewood plant. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout For a topic outline on this subject see List of basic Japan topics. With the solution to the problem of yaw control, the P-51H was now considered a suitable candidate for testing as an aircraft carrier based fighter; but with the end of the war, the testing was cut short, and production was halted after 555 aircraft were built. An aircraft carrier is a Warship designed with Although some P-51Hs were issued to operational units, none saw combat. One aircraft was given to the RAF for testing and evaluation. Serial number 44-64192 was re-serialled BuNo 09064 and used by the Navy to test transonic airfoil designs, then returned to the Air National Guard in 1952.

With the cutback in production the variants of the P-51H with different versions of the Merlin engine were produced in either limited numbers or terminated. These included the P-51L, similar to the P-51H but utilizing the 2270 horsepower V-1650-11 Merlin engine, which was never built; and its Dallas-built version, the P-51M or NA-124 which utilized the V-1650-9A Merlin engine lacking water injection and therefore rated for lower maximum power, of which one was built out of the original 1629 ordered, serial number 45-11743.
