 designs in operational use during World War II. The Allies countered its potential effectiveness in the air by relentlessly attacking the aircraft on the ground, or while they were taking off or landing. Maintenance problems and a lack of fuel during the deteriorating late-war situation also reduced the effectiveness of the aircraft as a fighting force. In the end, the Me 262 had a negligible impact on the course of the war due to its late introduction and the small numbers that were deployed in operational service.

The Me 262 influenced the designs of post-war aircraft such as the North American F-86 Sabre and Boeing B-47 Stratojet.

Design and development

The Me 262 was already being developed as Projekt 1065 (P.1065) before the start of World War II. Plans were first drawn up in April 1939, and the original design was very similar to the plane

 that Hitler originally had blocked mass production of the Me 262 before agreeing in early 1944. He rejected arguments that the aircraft would be more effective as a fighter against Allied bombers then destroying large parts of Germany, and wanted it as a bomber for revenge attacks.

Test flights

The first test flights began on 18 April 1941, with the Me 262 V1 example, bearing its Stammkennzeichen radio code letters of PC+UA, but since its intended BMW 003 turbojets were not ready for fitting, a conventional Junkers Jumo 210

 engine was mounted in the V1 prototype's nose, driving a propeller, to test the Me 262 V1 airframe. When the BMW 003 engines were finally installed, the Jumo was retained for safety, which proved wise as both 003s failed during the first flight and the pilot had to land using the nose-mounted engine alone. The BMW 003s were discovered to be subject to catastrophic failure due to the propwash entering the intakes during operation and they were permanently removed from the program in favor of the relatively reliable Junkers Jumo 004

 arrangement, initially a fixed undercarriage on the "V5" fifth prototype, then fully retractable on the sixth (V6, with Stammkennzeichen code VI+AA) and succeeding aircraft, corrected this problem.

Test flights continued over the next year, but engine problems continued to plague the project, the Jumo 004 being only marginally more reliable than the BMW 003. Airframe modifications were complete by 1942, but hampered by the lack of engines, serial production did not begin until 1944, but deliveries were low, with 28 Me 262s in June, 59 in July, but only 20 in August. This delay in engine availability was in part due to the shortage of strategic materials, especially metals and alloys able to handle the extreme temperatures produced by the jet engine.

Even when the engines were completed, they had an expected operational lifetime of approximately 50 continuous flight hours; most 004s lasted just 12 hours, even with adequate maintenance. A pilot familiar with the Me 262 and its engines could expect approximately 20–25 hours of life from the 004s. Changing a 004 engine was intended to require three hours, but this typically took eight to nine due to poorly made parts and inadequate training of ground crews.

. Used tactically, this gave the jet fighter an even greater speed advantage in climb rate than level flight at top speed.

With one engine out, the Me 262 still flew well, with speeds of 450–500 km/h (280–310 mph), but pilots were warned never to fly slower than 300 km/h (190 mph) on one engine, as the asymmetrical thrust would cause serious problems.

During March, Me 262 fighter units were able, for the first time, to mount large scale attacks on Allied bomber formations. On 18 March 1945, 37 Me 262s of JG 7 intercepted a force of 1,221 bombers and 632 escorting fighters. They shot down 12 bombers and one fighter for the loss of three Me 262s. Although a 4:1 ratio was exactly what the Luftwaffe would have needed to make an impact on the war, the absolute scale of their success was minor, as it represented only one per cent of the attacking force. In 1943 and early 1944, the USAAF had been able to keep up offensive operations despite loss ratios of 5% and more, and the few available Me 262s could not inflict sufficient losses to hamper their operations.

Despite its deficiencies, the Me 262 clearly signaled the beginning of the end of piston-engined aircraft as effective fighting machines. Once airborne, it could accelerate to speeds over 850 km/h (528 mph), about 150 km/h (90 mph) faster than any Allied fighter operational in the European Theater of Operations.

Anti-bomber tactics

The Me 262 was so fast that new tactics had to be devised to attack American bombers. In the head-on attack, the closing speed, of about 350 yd (320 m), was too high for accurate shooting. Even from astern, the closing speed was too great for the short-ranged 30 mm cannon to be used to maximum effect. Therefore, a roller-coaster attack was devised. The 262s approached from astern and about 6000 ft (1,828.8 m) than the bombers. From about 3 mi (4.8 km), they went into a shallow dive that took them through the escort fighters with little risk of interception. When they were about 1 mi (1.6 km) and 1500 feet (457.2 m) below the bombers, they pulled up sharply to reduce their excess speed. On levelling off, they were 1000 yd (0.9144 km) and overtaking the bombers at about 100 mph (160.9 km/h), well placed to attack them.

Since 30 mm cannon were not accurate above 650 yd (594.4 m), and since it was necessary to break off at 200 yd (182.9 m) to avoid colliding with the target, Me 262 pilots would normally commence firing at 550 yd (502.9 m). Allied bomber gunners found their electric gun turrets had problems tracking the jets. Target acquisition was difficult because the jets closed into firing range quickly and remained in firing position only briefly, using their standard attack profile which proved to be more effective.

s. For example, if you want to fight and destroy a B-17, you come in on a dive. The 30mm cannon were not so accurate above 650 yards. So you normally came in at 600 yards and would open fire on your B-17. And your closing speed was still high and since you had to break away at 200 yards to avoid a collision, you only had two seconds firing time. Now, in two seconds, you can’t sight. You can fire randomly and hope for the best. If you want to sight and fire, you need to double that time to four seconds. And with dive brakes, you could have done that."

Eventually, new combat tactics were developed to counter the Allied bombers' defences. Me 262s, equipped with R4M rockets, would approach from the side of a bomber formation, where their silhouettes were widest, and while still out of range of the bombers machine guns, fire a salvo

 filled warhead of only one or two of these rockets was capable of downing even the famously rugged B-17 Flying Fortress; a strike on an enemy aircraft meant its total annihilation.

. This method of attacking bombers became the standard until the invention and mass deployment of guided missiles. Some nicknamed this tactic the "Luftwaffe's Wolf Pack", as the fighters would often make runs in groups of two or three, fire their rockets, then return to base.

Counter-jet tactics

The Me 262 was difficult for its opponents to counter, once in the air, because of its high speed and rate of climb which made it extremely hard to intercept. As with all other early jets, the Me 262's engines did not provide a lot of thrust at low air speeds (a key criterion for good turn performance), and throttle response was slow. Another disadvantage shared by all early jet engines was the relatively high risk of flameout
Flameout
A flameout refers to the failure of a jet engine caused by the extinction of the flame in the combustion chamber. It can be caused by a number of factors, including fuel exhaustion; compressor stall; insufficient oxygen supply; foreign object damage ; severe inclement weather; and mechanical...

 if the throttle was used too aggressively (such as was common in a dogfight

). Pilots were therefore instructed to operate the throttle gently and avoid quick changes in setting. Later in the war, an automatic throttle regulator was introduced to try to solve this, but it only partly alleviated the problem. On the plus side, thrust at high speed was much greater than on propeller-driven aircraft.

Furthermore the Me 262 had, by contemporary standards, quite a high wing loading (60.2 lbs/ft2, 294.0 kg/m2) and its turn radius at low speeds was therefore correspondingly wide. This coupled with the slow throttle response and high chance of a flameout, resulted in Me 262 pilots being told to avoid low speed dogfights with the Allied piston engine fighters. The high speed of the Me 262 also presented problems when engaging enemy aircraft, the high speed convergence allowing Me 262 pilots little time to line up their targets or acquire the appropriate amount of deflection

. This is a problem which faces any aircraft which is approaching another one from behind at much higher speed, as the slower going aircraft in front will always be able to pull a tighter turn, forcing the faster aircraft to overshoot. This was a problem the Me 262 faced a lot, as its cruising speed alone was up to 200 km/h (124.3 mph) faster than that of any piston-engine fighter of the period. Oberst Johannes Steinhoff

 experienced this problem when he encountered a dozen Russian fighters early in 1945, the much higher speed of his Me 262 making it extremely difficult for him to get his guns on the small Russian fighters. He recalled:


I passed one that looked as if it was hanging motionless in the air (I am too fast!). The one above me went into a steep right-hand turn, his pale blue underside standing out against the purple sky. Another banked right in front of the Me's nose. Violent jolt as I flew through his airscrew eddies. Maybe a wing's length away. That one in the gentle left-hand curve! Swing her round. I was coming from underneath, eye glued to the sight (pull her tighter!). A throbbing in the wings as my cannon pounded briefly. Missed him. Way behind his tail. It was exasperating. I would never be able to shoot one down like this. They were like a sack of fleas. A prick of doubt: is this really such a good fighter? Could one in fact, successfully attack a group of erratically banking fighters with the Me 262?


Luftwaffe pilots did however eventually learn how to handle the Me 262's higher speed, and the Me 262 soon proved a formidable air superiority fighter, with pilots such as Franz Schall managing to shoot down 12 enemy fighters in the Me 262, 10 of them American P-51 Mustangs. Other notable Me 262 aces included Georg-Peter Eder

Despite its high wing loading and lack of low-speed thrust, pilots soon learned that the Me 262 was quite maneuverable, especially if attention was drawn to its effective maneuvering speeds. The controls were light and effective right up to the maximum permissible speed and perfectly harmonized. The addition of full span leading edge slats, in three unconnected sections on each wing, helped increase the overall lift produced by the wing by as much as 25 to 35% in tight turns or at low speeds, greatly improving the aircraft's turn performance as well as its landing and take off characteristics. (The slats lowered the stalling speed of the aircraft to a respectable 160 km/h (81.6 kn; 99.4 mph) depending on load out. They deployed automatically below 300 km/h (153.1 kn; 186.4 mph) on takeoff or landing, where the innermost (between fuselage and nacelle) was normally deployed, and at 450 km/h (229.6 kn; 279.6 mph) in turn or climb.) And as many pilots soon found out, the Me 262's clean design also meant that it, like all jets, held its speed in tight turns much better than conventional propeller driven fighters, which was a great potential advantage in a dogfight as it meant better energy retention in maneuvers. Luftwaffe test pilot and flight instructor Hans Fey stated, "The 262 will turn much better at high than at slow speeds, and due to its clean design, will keep its speed in tight turns much longer than conventional type aircraft."

Too fast to catch for the escorting Allied fighters, the Me 262s were almost impossible to head off. As a result, Me 262 pilots were relatively safe from the Allied fighters, as long as they did not allow themselves to get drawn into low-speed turning contests and saved their maneuvering for higher speeds. Combating the Allied fighters could be effectively done the same way as the U.S. fighters fought the more nimble, but slower, Japanese fighters in the Pacific.

Allied pilots soon found the only reliable way of dealing with the jets, as with the even faster Me 163 Komet

High speed research

Willy Messerschmitt regarded the Me 262 as only an interim type when it went into production.

Swept wings had been proposed as early as 1935 by Adolf Busemann

, and Messerschmitt had researched the topic from 1940. In April 1941, he proposed fitting a 35° swept wing (Pfeilflügel II, literally "arrow wing II") to the Me 262, the same wing sweep angle that would later be used on both the American F-86 Sabre and Soviet MiG-15 Fagot

 fighter jets. Though this was not implemented, he continued with the projected HG II and HG III (Hochgeschwindigkeit, "high speed") derivatives in 1944, which were designed with a 35° and 45° wing sweep, respectively.

Interest in high-speed flight, which led him to initiate work on swept wings starting in 1940, is evident from the advanced developments Messerschmitt had on his drawing board in 1944. While the Me 262 HG I actually flight tested in 1944 had only small changes compared to combat aircraft, most notably a low-profile canopy (tried as the Rennkabine (literally "racing cabin") on the Me 262 V9 prototype for a short time) to reduce drag, the HG II and HG III designs were far more radical. The projected HG II combined the low-drag canopy with a 35° wing sweep and a butterfly tail. The HG III had a conventional tail, but a 45° wing sweep and turbines embedded in the wing root

s.

Messerschmitt also conducted a series of flight tests with the series production Me 262. In dive tests, it was determined that the Me 262 went out of control in a dive at Mach

 loads.

The HG series of Me 262 derivatives was estimated to be capable of reaching transonic Mach numbers in level flight, with the top speed of the HG III being projected as Mach 0.96 at 6,000 m (19,690 ft) altitude. Despite the necessity to gain experience in high-speed flight for the HG II and III designs, Messerschmitt undertook no attempts to exceed the Mach 0.86 limit for the Me 262.

After the war, the Royal Aircraft Establishment

The RAE achieved speeds of up to Mach 0.84 and confirmed the results from the Messerschmitt dive tests. Similar tests were run by the Soviets. No attempts were made to exceed the Mach limit established by Messerschmitt.

 claimed to be the first person to exceed Mach 1, on 9 April 1945 in a Me 262 in a "straight-down" 90° dive. This claim is disputed because it is only based on Mutke's memory of the incident, which recalls effects other Me 262 pilots observed below the speed of sound at high indicated airspeed, but with no altitude reading required to determine the actual speed. Furthermore, the pitot tube

One airframe (Me 262 HG1 V9, Werknummer 130 004, with Stammkennzeichen of VI+AD) was prepared with the low-profile Rennkabine racing canopy and may have achieved an unofficial record speed for a turbojet-powered aircraft of 975 km/h (606 mph), altitude unspecified.

Production

While Germany was bombed intensively, production of the Me 262 was dispersed into low-profile production facilities, sometimes little more than clearings in the forests of Germany and occupied countries. Through the end of February to the end of March 1945, approximately 60 Me 262s were destroyed in attacks on Obertraubling

Large, heavily protected underground factories were constructed to take up production of the Me 262, safe from bomb attacks, but the war ended before they could be completed. At B8 Bergkristall-Esche II at St. Georgen/Gusen, Austria, forced labourers of Concentration Camp Gusen II produced fully equipped fuselages for the Me 262 at a monthly rate of 450 units on large assembly lines from early 1945.

Postwar history

After the end of the war, the Me 262 and other advanced German technologies were quickly swept up by the Americans (as part of the USAAF's Operation Lusty

), British, and Soviets. Many Me 262s were found in readily-repairable condition and were confiscated.

During testing, the Me 262 was found to have advantages over the early models of the Gloster Meteor

. It was faster, had better cockpit visibility to the sides and rear (mostly due to the canopy frame and the discoloration caused by the plastics used in the Meteor's construction), and was a superior gun platform, as the early Meteors had a tendency to snake at high speed and exhibited "weak" aileron response. The Me 262 did have a shorter combat range than the Meteor.

The USAAF compared the P-80 Shooting Star and Me 262 concluding, "Despite a difference in gross weight of nearly 2000 lb (907.2 kg), the Me 262 was superior to the P-80 in acceleration, speed and approximately the same in climb performance. The Me 262 apparently has a higher critical Mach number, from a drag standpoint, than any current Army Air Force fighter."

The Army Air Force also tested an example of the Me 262A-1a/U3 (US flight evaluation serial FE-4012), an unarmed photo reconnaissance version, which was fitted with a fighter nose and given an overall smooth finish. It was used for performance comparisons against the P-80. During testing between May and August 1946, the aircraft completed eight flights, lasting four hours and 40 minutes. Testing was discontinued after four engine changes were required during the course of the tests, culminating in two single-engine landings.

These aircraft were extensively studied, aiding development of early U.S. and Soviet jet fighters. The F-86, designed by engineer
