, more recent research including scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 offered the additional advantage of low cost, which kept it in production as a ground-attack fighter long after it was obsolete in the air superiority role. As of 2008, 19 P-40s were airworthy.

Design and development

On 14 October 1938, Curtiss test pilot Edward Elliott flew the prototype XP-40, on its first flight in Buffalo. The XP-40 was the 10th production Curtiss P-36 Hawk, with its Pratt & Whitney R-1830 (Twin Wasp) 14-cylinder air-cooled radial engine

 flew this prototype some 300 miles in 57 minutes, approximately 315 miles per hour (140.8 m/s). Hiding his disappointment, he told reporters that future versions would likely go 100 mph faster. Kelsey was interested in the Allison engine because it was sturdy and dependable, and it had a smooth, predictable power curve. The V-12 engine offered as much power as a radial engine but had a smaller frontal area and allowed a more streamlined cowl than an aircraft with radial engines, promising a theoretical 5% increase in top speed.

Curtiss engineers worked to improve the XP-40's speed by moving the radiator forward in steps. Seeing little gain, Kelsey ordered the aircraft to be evaluated in a NACA

 wind tunnel to identify solutions for better aerodynamic qualities. From 28 March to 11 April 1939, the prototype was studied by NACA. Based on the data obtained, Curtiss moved the glycol coolant radiator forward to the chin; its new air scoop also accommodated the oil cooler air intake. Other improvements to the landing gear doors and the exhaust manifold combined to give performance that was satisfactory to the USAAC. Without beneficial tail winds, Kelsey flew the XP-40 from Wright Field back to Curtiss's plant in Buffalo at an average speed of 354 mph (158.3 m/s). Further tests in December 1939 proved the fighter could reach 366 mph (163.6 m/s).

An unusual production feature was a special truck rig to speed delivery at the main Curtiss plant in Buffalo, New York. The rig moved the newly built P-40s in two main components, the main wing and the fuselage, the eight miles from the plant to the airport where the two units were mated for flight and delivery.

s in each wing to be inadequate. This was rectified with the P-40E Kittyhawk, which had three .50 in (12.7 mm) guns in each wing, although Caldwell preferred the Tomahawk in other respects. It had armour around the engine and the cockpit, which enabled it to withstand considerable damage. This was one of the characteristics that allowed Allied pilots in Asia and the Pacific to attack Japanese fighters head on, rather than try to out-turn and out-climb their opponents. Late-model P-40s were regarded as well armored. Visibility was adequate, although hampered by an overly complex windscreen frame, and completely blocked to the rear in early models due to the raised turtledeck. Poor ground visibility and the relatively narrow landing gear track led to many losses due to accidents on the ground.

Operational history

In April 1939, the U.S. Army Air Corps, witnessing the new sleek, high speed, in-line-engined fighters of the European air forces, placed the largest single fighter order it had ever made for fighters: 524 P-40s.

The P-40 initially proved quite effective against Axis aircraft and contributed to a slight shift of momentum in the Allied favor. The gradual replacement of Hurricanes by the Tomahawks and Kittyhawks led to the Luftwaffe accelerating retirement of the Bf 109E and introducing the newer Bf 109F; these were to be flown by the veteran pilots of elite Luftwaffe units, such as Jagdgeschwader 27

 (JG27), in North Africa.

The P-40 was generally considered roughly equal or slightly superior to the Bf 109 at low altitude, but inferior at high altitude, particularly against the Bf 109F. Most air combat in North Africa took place well below 16000 ft (4,876.8 m), thus negating much of the Bf 109's superiority. The P-40 usually had an edge over Bf 109 in horizontal maneuverability, dive speed and structural strength, was roughly equal in firepower, but was slightly inferior in speed and outclassed in rate of climb and operational ceiling.

The P-40 was generally superior to early Italian fighter types, such as the Fiat G.50

Some DAF units initially failed to use P-40s according to its strengths and/or utilised outdated defensive tactics, such as the Lufbery circle. However, the superior climb rate of the Bf 109 enabled fast, swooping attacks, neutralizing the advantages offered by conventional defensive tactics. Various new formations were tried by Tomahawk units in 1941-42, including: "fluid pairs" (similar to the German rotte); one or two "weavers" at the back of a squadron in formation, and whole squadrons bobbing and weaving in loose formations.

, recruited from U.S. aviators. From late 1941, the P-40B was used by the Flying Tigers. They were divided into three pursuit squadrons, the "Adam & Eves", the "Panda Bears" and the "Hell's Angels".

Compared to opposing Japanese fighters, the P-40B's strengths were that it was sturdy, well armed, faster in a dive and possessed an excellent rate of roll. While the P-40s could not match the maneuverability of the Japanese Army air arm's Nakajima Ki-27

, nor the much more famous Zero naval fighter in a slow speed turning dogfight, at higher speeds the P-40s were more than a match. AVG leader Claire Chennault trained his pilots to use the P-40's particular performance advantages. The P-40 had a higher dive speed than any Japanese fighter aircraft of the early war years, for example, and could be used to exploit so-called "boom-and-zoom" tactics. The AVG was highly successful, and its feats were widely-published, to boost sagging public morale at home, by an active cadre of international journalists. According to their official records, in just 6 1/2 months, the Flying Tigers destroyed 297 enemy aircraft for the loss of just four of their own (in air-to-air combat).

 created a joint P-40 management and replacement pool on 30 July 1942 and many P-40s went back and forth between both air forces.

The 49th Fighter Group was in action in the Pacific from the beginning of the war. Robert DeHaven scored 10 kills (from 14 kills overall) in the P-40 with the 49th FG. He compared the P-40 favorably with the P-38:
"If you flew wisely, the P-40 was a very capable aircraft. [It] could outturn a P-38, a fact that some pilots didn't realise when they made the transition between the two aircraft. [...] The real problem with it was lack of range. As we pushed the Japanese back, P-40 pilots were slowly left out of the war. So when I moved to P-38s, an excellent aircraft, I did not [believe] that the P-40 was an inferior fighter, but because I knew the P-38 would allow us to reach the enemy. I was a fighter pilot and that was what I was supposed to do."


The 8th, 15th, 18th, 24th, 49th, 343rd and 347th PGs/FGs, flew P-40s in the Pacific theaters, between 1941 and 1945, with most units converting to P-38s during 1943-44. In 1945, the 71st Reconnaissance Group employed them as armed forward air controllers during ground operations in the Philippines until it received delivery of P-51s. They claimed 655 aerial victories.

Contrary to conventional wisdom, with sufficient altitude the P-40 could actually turn with the A6M and other Japanese fighters, using a combination of nose-down vertical turn with a bank turn, a technique known as a low yo-yo. Robert DeHaven describes how this tactic was used in the 49th Fighter group:
[Y]ou could fight a Jap on even terms, but you had to make him fight your way. He could outturn you at slow speed. You could outturn him at high speed. When you got into a turning fight with him, you dropped your nose down so you kept your airspeed up, you could outturn him. At low speed he could outroll you because of those big ailerons ... on the Zero. If your speed was up over 275, you could outroll [a Zero]. His big ailerons didn't have the strength to make high speed rolls... You could push things, too. Because ... [i]f you decided to go home, you could go home. He couldn't because you could outrun him. [...] That left you in control of the fight.

 973 kills in the theater, or 64.8 percent of all enemy aircraft shot down. Aviation historian Carl Molesworth stated that "...the P-40 simply dominated the skies over Burma and China. They were able to establish air superiority over free China, northern Burma and the Assam valley of India in 1942, and they never relinquished it."

While the P-40 suffered heavy loses in the MTO, many USAAF P-40 units achieved high kill-to-loss ratios against Axis aircraft. For example, the 324th FG scored better than a 2:1 ratio in the MTO. In all, 23 U.S. pilots became aces in the MTO while flying the P-40, most of them during the first half of 1943. As in the Pacific, success in combat depended in part on experience and effective tactics.

Individual pilots from the 57th FG were the first USAAF P-40 pilots to see action in the MTO, while attached to Desert Air Force Kittyhawk squadrons, from July 1942.

An anecdote concerning the 325th FG, indicates what could happen if Bf 109 pilots made the mistake of trying to out-turn the P-40. 325th FG historian Carol Cathcart wrote: "on 30 July, 20 P-40s of the 317th [Fighter Squadron] ... took off on a fighter sweep ... over Sardinia

The much-lightened P-40L was most heavily used in the MTO, primarily by U.S. pilots. Many US pilots stripped down their P-40s even further to improve performance, often removing two or more of the wing guns from the P-40F/L.

 (MA; "Naval Air Service") also referred to P-40s as Tomahawks and Kittyhawks. In fact, the Curtiss P-40 Tomahawk/Kittyhawk was the first Allied fighter supplied to the USSR under the Lend-Lease agreement.
Their units used 2,097 146 Tomahawks were shipped from Great Britain and 49 more arrived from the US, many of them coming incomplete, lacking machine guns and even the lower half of the engine cowling. In late September 1941, the first 48 P-40s were assembled and checked in USSR. Test flights showed some manufacturing defects: generator and oil pump gears and generator shafts failed repeatedly, which led to emergency landings. The test report indicated that the Tomahawk was inferior to Soviet "M-105P-powered production fighters in speed and rate of climb. However, it has good short field performance, horizontal manoeuvrability, range and endurance".
Nevertheless, Tomahawks and Kittyhawks were used against the Germans. The 126th IAP fighting on the Western and Kalinin fronts were the first unit to receive the P-40. The regiment entered action on 12 October 1941. By 15 November 1941, that unit had shot down 17 German aircraft. However, Lt (SG) Smirnov noted that the P-40 armament was sufficient for strafing enemy lines but rather ineffective in aerial combat. Another pilot, S.G. Ridnyy (Hero of Soviet Union), remarked that he had to shoot half the ammunition at 50–100 meters (164–339 ft) to shoot down an enemy aircraft.

In January 1942, some 198 aircraft sorties were flown (334 flying hours) and 11 aerial engagements were conducted, in which five Bf 109s, one Ju 88, and one He 111 were downed. These statistics reveal a surprising fact: it turns out that the Tomahawk was fully capable of successful air combat with a Bf 109. The reports of pilots about the circumstances of the engagements confirm this fact. On 18 January 1942, Lieutenants S. V. Levin and I. P. Levsha (in pair) fought an engagement with seven Bf 109s and shot down two of them without loss. On 22 January, a flight of three aircraft led by Lieutenant E. E. Lozov engaged 13 enemy aircraft and shot down two Bf 109Es, again without loss. Altogether, in January, two Tomahawks were lost; one downed by German antiaircraft artillery and one lost to Messerschmitts.

The Soviets stripped down their P-40s significantly for combat, in many cases removing the wing guns altogether in P-40B/C types, for example. Soviet Air Force reports state that they liked the range and fuel capacity of the P-40 which were superior to most of the Soviet fighters, though they still preferred the P-39. Soviet pilot Nikolai G. Golodnikov recalled: "The cockpit was vast and high. At first it felt unpleasant to sit waist-high in glass, as the edge of the fuselage was almost at waist level. But the bullet-proof glass and armoured seat were strong and visibility was good. The radio was also good. It was powerful, reliable, but only on HF (high frequency). The American radios did not have hand microphones but throat microphones. These were good throat mikes: small, light and comfortable." The biggest complaint of some Soviet airmen was its poor climb rate and problems with maintenance, especially with burning out the engines. VVS pilots usually flew the P-40 at War Emergency Power settings while in combat, this would bring the acceleration and speed performance closer to that of their German rivals, but could burn out engines in a matter of weeks. They also had difficulty with the more demanding requirements for fuel quality and oil purity of the Allison engines. A fair number of burnt out P-40s were re-engined with Soviet Klimov engines but these performed relatively poorly and were relegated to rear area use.
The P-40 saw the most front line use in Soviet hands in 1942 and early 1943. It was used in the northern sectors and played a significant role in the defense of Leningrad
Siege of Leningrad
The Siege of Leningrad, also known as the Leningrad Blockade was a prolonged military operation resulting from the failure of the German Army Group North to capture Leningrad, now known as Saint Petersburg, in the Eastern Front theatre of World War II.

. The most numerically important types were P-40B/C, P-40E and P-40K/M. By the time the better P-40F and N types became available, production of superior Soviet fighters had increased sufficiently so that the P-40 was replaced in most Soviet Air Force units by the Lavochkin La-5

 and various later Yakovlev types. In spring 1943, Lt D.I. Koval of the 45th IAP gained ace status on the North-Caucasian front, shooting down six German aircraft flying a P-40. Some Soviet P-40 squadrons had good combat records. They provided close air support as well as air-to-air capability while Soviet pilots became aces on the P-40, not as many as on the P-39 Airacobra, which was the most numerous Lend Lease fighter used by the Soviet Union. However Soviet commanders considered the Kittyhawk to significantly outclass the Hurricane, although it was "not in the same league as the Yak-1".

Variants and development stages


XP-40
The original Curtis XP-40, ordered July 1937, was converted from the 10th P-36A by replacing the radial engine with a new Allison V-1710-19 engine. It flew for the first time in October 1938.

This new liquid-cooled engine fighter had a radiator mounted under the rear fuselage
but the prototype XP-40 was later modified and the radiator was moved forward under the engine.
P-40
The P-40 (Curtiss Model 81A-1) was the first production variant, 199 built.

P-40A
One P-40 was modified with a camera installation in the rear fuselage and re-designated P-40A.
  • Revised versions of the P-40 soon followed: the P-40B or Tomahawk IIA had extra .30in in (7.62 mm) U.S., or .303 in
    .303 British
    .303 British, or 7.7x56mmR, is a .311 inch calibre rifle and machine gun cartridge first developed in Britain as a blackpowder round put into service in December 1888 for the Lee-Metford rifle, later adapted to use smokeless powders...

     (7.7 mm) machine guns in the wings and a partially protected fuel system; the P-40C or Tomahawk IIB added underbelly drop tank and bomb shackles, self-sealing fuel tanks and other minor revisions, but the extra weight did have a negative impact on aircraft performance. (All versions of the P-40 had a relatively low power-to-weight ratio compared to contemporary fighters.)
  • Only a small number of P-40D or Kittyhawk Mk Is were made, less than 50. With a new, larger Allison engine, slightly narrower fuselage, redesigned canopy, and improved cockpit, the P-40D eliminated the nose-mounted .50 in (12.7 mm) guns and instead had a pair of .50 in (12.7 mm) guns in each wing. The distinctive chin airscoop grew larger in order to adequately cool the large Allison engine.
  • Retrospective designation for a single prototype. The P-40A was a single camera-carrying aircraft.
  • The P-40E or P-40E-1 was similar in most respects to the P-40D, except for a slightly more powerful engine and an extra .50 in (12.7 mm) gun in each wing, bringing the total to six. Some aircraft also had small underwing bomb shackles. Supplied to the Commonwealth air forces as the Kittyhawk Mk IA. The P-40E was the variant that bore the brunt of air-to-air combat by the type in the key period of early to mid 1942, for example with the first US squadrons to replace the AVG in China (the AVG was already transitioning to this type from the P-40B/C), the type used by the Australians at Milne Bay, by the New Zealand squadrons during most of their air to air combat, and by the RAF/Commonwealth in North Africa as the Kittyhawk IA.

    ", after a famous stripper of the era, due to its stripped-down condition. Supplied to the Commonwealth air forces under the designation Kittyhawk Mk II, a total of 330 Mk IIs were supplied to the RAF under Lend-Lease. The first 230 aircraft are sometimes known as the Kittyhawk Mk IIA. The P-40F/L was extensively used by U.S. fighter groups operating in the Mediterranean Theater.
  • P-40G : 43 P-40 aircraft fitted with the wings of the Tomahawk Mk IIA. A total of 16 aircraft were supplied to the Soviet Union, and the rest to the US Army Air Force. It was later redesignated RP-40G.
  • P-40K, an Allison-engined P-40L, with the nosetop scoop retained and the Allison configured scoop and cowl flaps. Supplied to the Commonwealth air forces as the Kittyhawk Mk III, it was widely used by US units in the CBI.
  • P-40M, version generally similar to the P-40K, with a stretched fuselage like the P-40L and powered by an Allison V-1710-81 engine giving better performance at altitude (compared to previous Allison versions). It had some detail improvements and it was characterized by two small air scoops just before the exhaust pipes. Most of them were supplied to Allied countries (mainly UK and USSR), while some others remained in the USA for advanced training. It was also supplied to the Commonwealth air forces as the Kittyhawk Mk. III.
  • P-40N (manufactured 1943–44), the final production model. The P-40N featured a stretched rear fuselage to counter the torque of the larger, late-war Allison engine, and the rear deck of the cockpit behind the pilot was cut down at a moderate slant to improve rearward visibility. A great deal of work was also done to try and eliminate excess weight to improve the Warhawk's climb rate. Early N production blocks dropped a .50 in (12.7 mm) gun from each wing, bringing the total back to four; later production blocks reintroduced it after complaints from units in the field. Supplied to Commonwealth air forces as the Kittyhawk Mk IV. A total of 553 P-40Ns were acquired by the Royal Australian Air Force, making it the variant most commonly used by the RAAF. Subvariants of the P-40N ranged widely in specialization from stripped down four-gun "hot rods" which could reach the highest top speeds of any production variant of the P-40 (up to 380 mph), to overweight types with all the extras intended for fighter-bombing or even training missions.

  • P-40P : The designation of 1,500 aircraft ordered with V-1650-1 engines, but actually built as the P-40N with V-1710-81 engines.

    , supercharger, squared-off wingtips and tail surfaces, and improved engine with two-speed supercharger was tested, but its performance was not enough of an improvement to merit production when compared to the contemporary late model P-47Ds and P-51Ds pouring off production lines. The XP-40Q was, however, the fastest of the P-40 series with a top speed of 422 mph (679.1 km/h) as a result of the introduction of a high altitude supercharger gear. (No P-40 model with a single-speed supercharger could even approach 400 mph (643.7 km/h)) With the end of hostilities in Europe, the P-40 came to the end of its front line service.
  • P-40R : The designation of P-40F and P-40L aircraft, converted into training aircraft in 1944.
  • RP-40 : Some American P-40s were converted into reconnaissance aircraft.
  • TP-40 : Some P-40s were converted into two-seat trainers.
  • Twin P-40 : Probably the most unusual variant, it was a P-40C outfitted in 1942 with a pair of 1,300 hp (969 kW) Packard V-1650-1 Merlin

Survivors

Of the 13,738 P-40s built, only 19 P-40s remain airworthy, with three of them being converted to dual-controls/dual-seat configuration. Approximately 80 aircraft are on static display or under restoration.
