The Messerschmitt Me 262 Schwalbe ("Swallow") was the world's first operational jet-powered fighter aircraft. Design work started before World War II began but engine problems prevented the aircraft from attaining operational status with the Luftwaffe until mid-1944. Compared with Allied fighters of its day, including the jet-powered Gloster Meteor, it was much faster and better armed. One of the most advanced aviation designs in operational use during World War II, the Me 262 was used in a variety of roles, including light bomber, reconnaissance and even experimental night fighter versions. Me 262 pilots claimed a total of 542 Allied kills (although higher claims are sometimes made) against the loss of about 100 Me 262s. The Allies countered its potential effectiveness in the air by relentlessly attacking the aircraft on the ground and 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 eventually entered service. The progression of the original design into service was delayed greatly by technical issues involving the new jet engines. Funding for the jet program was also initially lacking as many high-ranking officials thought the war could easily be won with conventional aircraft.

Among those were: Hermann Göring, head of the Luftwaffe, who cut the engine development program to just 35 engineers in February 1940; Willy Messerschmitt, who desired to maintain mass production of the Bf 109 and the projected Me 209; and Major General Adolf Galland, who supported Messerschmitt through the early development years, flying the Me 262 himself on 22 April 1943. By that time, problems with engine development had slowed production of the aircraft considerably.

The project aerodynamicist on the design of the Me 262 was Ludwig Bölkow, later a prominent figure in the post-World War II development of the German aircraft industry. He initially designed the wing using NACA airfoils modified with an elliptical nose section. Later in the design process, these were changed to AVL derivatives of NACA airfoils, the NACA 00011-0.825-35 being used at the root and the NACA 00009-1.1-40 at the tip.

The elliptical nose derivatives of the NACA airfoils were used on the horizontal and vertical tail surfaces. Wings were single-spar cantilever construction, with stressed skins, varying from 3 mm (0.12 in) thick at the root to 1 mm (0.039 in) at the tip. The wings were fastened to the fuselage at four points, using a pair of 20 mm (0.79 in) and forty-two 8 mm (0.31 in) bolts.

In mid-1943, Adolf Hitler envisioned the Me 262 as an offensive ground-attack/bomber rather than a defensive interceptor. The configuration of a high speed, light payload Schnellbomber ("Fast Bomber") was intended to penetrate enemy airspace during the expected Allied invasion of France. His edict resulted in the development of (and concentration on) the Sturmvogel variant. It is debatable to what extent Hitler's interference extended the delay in bringing the Schwalbe into operation.

Albert Speer, then Minister of Armaments and War Production, claimed in his memoirs 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 destroying large parts of Germany, and wanted it as a bomber for revenge attacks. According to Speer, Hitler felt its superior speed compared to other fighters of the era meant it could not be attacked and so preferred it for high altitude straight flying.

Although the Me 262 is often referred to as a "swept wing" design, the production Me 262 had a leading edge sweep of only 18.5°, too slight to achieve any significant advantage in increasing the critical Mach number. Sweep was added after the initial design of the aircraft, when the engines proved to be heavier than originally expected, primarily to position the center of lift properly relative to the centre of mass. On 1 March 1940, instead of moving the wing forward on its mount, the outer wing was repositioned slightly aft; the trailing edge of the mid-section of the wing remained unswept. Based on data from the AVA Göttingen and wind tunnel results, the middle section's leading edge was later swept to the same angle as the outer panels.

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.

This airframe, Wrknr. 111711, was the first Me 262 to come into Allies hands when its test pilot defected in March 1945. It was subsequently lost in August 1946, the US test pilot parachuting to safety.

The V3 third prototype airframe, with the code PC+UC, became a true "jet" when it flew on 18 July 1942 in Leipheim near Günzburg, Germany, piloted by Fritz Wendel. This was almost nine months ahead of the British Gloster Meteor's first flight on 5 March 1943. The conventional gear — producing a pronounced tail-down attitude on the ground — of the Me 262 V3 caused its jet exhaust to deflect off the runway, with the wing's turbulence negating the effects of the elevators, and the first takeoff attempt was cut short.

On the second attempt, Wendel solved the problem by tapping the aircraft's brakes at takeoff speed, lifting the horizontal tail out of the wing's turbulence. The first four prototypes (V1-V4) were built with this configuration. Changing to a tricycle 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.

Turbojet engines have less thrust at low speed than propellers, and as a result, low-speed acceleration is relatively poor. It was more noticeable for the Me 262 as early jet engines (before the invention of afterburners) responded slowly to throttle changes. The introduction of a primitive autothrottle late in the war only helped slightly. Conversely, the higher power of jet engines at higher speeds meant the Me 262 enjoyed a much higher rate of climb. 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.

Operationally, carrying 2,000 L (440 imp gal; 530 US gal) of fuel (in two 900 L (200 imp gal; 240 US gal) tanks, one each fore and aft the cockpit, and a 200 L (44 imp gal; 53 US gal) tank beneath), the Me 262 had an endurance of 60 to 90 minutes. Fuel was usually brown coal-derived J2, with the option of diesel oil or a mixture of oil and high octane B4 aviation petrol. Consumption was double the usual for a twin-engine Luftwaffe aircraft, so a low-fuel warning came on when levels fell below 250 L (55 imp gal; 66 US gal).

Unit cost for an Me 262 airframe, less engines, armament, and electronics, was RM87,400. (By comparison, a new Volkswagen Type 1 was priced at RM990.) To build one airframe took around 6,400 man-hours.

Operational history

Me 262 A-1a.

On 19 April 1944, Erprobungskommando 262 was formed at Lechfeld just south of Augsburg, Bavaria as a test unit (Jäger Erprobungskommando Thierfelder, commanded by Hauptmann Werner Thierfelder) to introduce the 262 into service and train a core of pilots to fly it. On 26 July 1944, Leutnant Alfred Schreiber with the 262 A-1a W.Nr. 130 017 damaged a Mosquito reconnaissance aircraft of No. 540 Squadron RAF PR Squadron, which was allegedly lost in a crash upon landing at an air base in Italy. Other sources state the aircraft was damaged during evasive manoeuvres and escaped.

It was the first victory for a turbojet fighter aircraft in aviation history. Major Walter Nowotny was assigned as commander after the death of Thierfelder in July 1944, and the unit redesignated Kommando Nowotny. Essentially a trials and development unit, it holds the distinction of having mounted the world's first jet fighter operations. Trials continued slowly, with initial operational missions against the Allies in August 1944 allegedly downing 19 Allied aircraft for six Me 262s lost, although these claims have never been verified by cross-checking with USAAF records. The RAF Museum holds no intelligence reports of RAF aircraft engaging in combat with Me 262s in August, although there is a report of an unarmed encounter between an Me 262 and a Mosquito.

Despite orders to stay grounded, Nowotny chose to fly a mission against an enemy bomber formation flying some 30,000 feet above, on 8 November 1944. He claimed two P-51Ds destroyed before suffering engine failure at high altitude. Then, while diving and trying desperately to restart his engines, he was attacked, by other Mustangs, and forced to bail out. Some U.S. historians proposed Nowotny's victor was P-51D pilot Lt. Robert W Stevens of the 364th Fighter Group. According to other sources, he was shot down and killed by First Lieutenant Edward "Buddy" Haydon of the 357th Fighter Group and Captain Ernest "Feeb" Fiebelkorn of the 20th Fighter Group, both USAAF.

Actually, the exact circumstances surrounding the death of Walter Nowotny remain uncertain to this day. It is also possible he was hit by "friendly" flak. The Kommando was then withdrawn for further training and a revision of combat tactics to optimise the 262's strengths.

Me 262 A, circa 1944/45

By January 1945, Jagdgeschwader 7 (JG 7) had been formed as a pure jet fighter wing, although it would be several weeks before it was operational. In the meantime, a bomber unit – I Gruppe, Kampfgeschwader 54 (KG 54) – had re-equipped with the Me 262 A-2a fighter-bomber for use in a ground-attack role. However, the unit lost 12 jets in action in two weeks for minimal returns.

Jagdverband 44 (JV 44) was another Me 262 fighter unit, of Staffel (squadron) size given the low numbers of available personnel, formed in February 1945 by Lieutenant General Adolf Galland, who had recently been dismissed as Inspector of Fighters. Galland was able to draw into the unit many of the most experienced and decorated Luftwaffe fighter pilots from other units grounded by lack of fuel.

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.

Several two-seat trainer variants of the Me 262, the Me 262 B-1a, had been adapted through the Umrüst-Bausatz 1 factory refit package as night fighters, complete with on-board FuG 218 Neptun high-VHF band radar, using Hirschgeweih ("stag's antlers") antennae with a set of shorter dipole elements than the Lichtenstein SN-2 had used, as the B-1a/U1 version. Serving with 10 Staffel, Nachtjagdgeschwader 11, near Berlin, these few aircraft (alongside several single-seat examples) accounted for most of the 13 Mosquitoes lost over Berlin in the first three months of 1945. However, actual intercepts were generally or entirely made using Wilde Sau methods, rather than AI radar-controlled interception. As the two-seat trainer was largely unavailable, many pilots had to make their first flight in a jet in a single-seater without an instructor.

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 (530 mph), about 150 km/h (93 mph) faster than any Allied fighter operational in the European Theater of Operations.

The Me 262's top ace was probably Hauptmann Franz Schall with 17 kills which included six four-engine bombers and 10 P-51 Mustang fighters, although night fighter ace Oberleutnant Kurt Welter claimed 25 Mosquitos and two four-engine bombers shot down by night and two further Mosquitos by day flying the Me 262. Most of Welter's claimed night kills were achieved in standard radar-less aircraft, even though Welter had tested a prototype Me 262 fitted with FuG 218 Neptun radar. Another candidate for top ace on the aircraft was Oberstleutnant Heinrich Bär, who claimed 16 enemy aircraft while flying the Me 262.

Anti-bomber tactics

B-17G 44-6387 of the 815th Bombardment Squadron was lost on the mission to Ruhland, Germany on 22 March 1945, the bomber being hit first by Flak, then finished off by an Me 262. Eight survived as POWs.

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 per second (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 6,000 ft higher (1,800 m) than the bombers. From about 3 mi behind (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 astern (1.6 km) and 1,500 feet (460 m) below the bombers, they pulled up sharply to reduce their excess speed. On levelling off, they were 1,000 yd astern (0.91 km) and overtaking the bombers at about 100 mph (160 km/h), well placed to attack them.

Since 30 mm cannon were not accurate beyond 650 yd (590 m), and it was necessary to break off at 200 yd (180 m) to avoid colliding with the target, Me 262 pilots would normally commence firing at 550 yd (500 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.

Captain Eric Brown, Chief Naval Test Pilot and C.O. Captured Enemy Aircraft Flight Royal Aircraft Establishment, who tested the Me 262 noted: "This was a Blitzkrieg aircraft. You whack in at your bomber. It was never meant to be a dogfighter, it was meant to be a destroyer of bombers... The great problem with it was it did not have dive brakes. 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 beyond 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 of rockets. The Hexogen 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.

Although this tactic was effective, it came too late to have a real effect on the war, and only small numbers of Me 262s were actually equipped with the rocket packs. Most of those so equipped were Me 262A-1as, members of Jagdgeschwader 7. 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.

On 1 September 1944, USAAF General Carl Spaatz expressed the fear that if greater numbers of German jets appeared, they could inflict losses heavy enough to force cancellation of the Allied bombing offensive by daylight.

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 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 frequently, as its cruising speed alone was up to 200 km/h (120 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, also with 12 enemy fighters to his credit (including 9 P-51s), Walther Dahl with 11 (including three La-7s and six P-51s) and Heinz-Helmut Baudach with 6 (including 1 Spitfire and 2 P-51s) amongst many others.

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 to 170 km/h (86 to 92 kn; 99 to 106 mph) depending on load out. They deployed automatically below 300 km/h (160 kn; 190 mph) on takeoff or landing, where the innermost (between fuselage and nacelle) was normally deployed, and at 450 km/h (240 kn; 280 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 rocket fighters, was to attack them on the ground and during takeoff or landing. Luftwaffe airfields identified as jet bases were frequently bombed by medium bombers, and Allied fighters patrolled over the fields to attack jets trying to land. The Luftwaffe countered by installing extensive flak alleys of anti-aircraft guns along the approach lines in order to protect the Me 262s from the ground, and providing top cover during the jets' takeoff and landing with the most advanced Luftwaffe single-engined fighters, the Focke-Wulf Fw 190D and (just becoming available in 1945) Focke-Wulf Ta 152H. Nevertheless, in March–April 1945, Allied fighter patrol patterns over Me 262 airfields resulted in numerous losses of jets and serious attrition of the force.

High speed research

Me 262 interior

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 roots.

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 0.86, and that higher Mach numbers would lead to a nose-down trim that could not be countered by the pilot. The resulting steepening of the dive would lead to even higher speeds and disintegration of the airframe due to excessive negative g 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 (20,000 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, at that time one of the leading institutions in high-speed research, re-tested the Me 262 to help with British attempts at exceeding Mach 1. 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.

After Willy Messerschmitt's death, the former Me 262 pilot Hans Guido Mutke 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 used to measure airspeed in aircraft can give falsely elevated readings as the pressure builds up inside the tube at high speeds. Finally, the Me 262 wing had only a slight sweep incorporated for trim (center of gravity) reasons and likely would have suffered structural failure due to divergence at high transonic speeds. 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

Underground manufacture of Me 262s

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 and 30 at Leipheim (the Neuberg jet plant was bombed on 19 March.) 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.

Wings for the Me 262 were produced in Germany's oldest motorway tunnel at Engelberg to the west of Stuttgart. In the end, slightly over 1,400 Me 262s of all versions were produced. As few as 200 Me 262s made it to combat units due to fuel shortages, pilot shortages, and the lack of airfields that could support the Me 262.

Postwar history

Reproduction of a Messerschmitt Me 262 at the Berlin Air Show 2006

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. Both the Soviets and Americans desired the technology to serve as a basis for their own jet fighters.

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 2,000 lb (900 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 Edgar Schmued, used a slat design based on the Me 262's.

Avia S-92, Kbely museum

The Czechoslovak aircraft industry continued to produce single-seat (Avia S-92) and two-seat (Avia CS-92) variants of the Me 262 after World War II. From August 1946, a total of nine S-92s and three two-seater CS-92s were completed and test flown. They were introduced in 1947 and in 1950 were supplied to the 5th Fighter Squadron, becoming the first jet fighters to serve in the Czechoslovak Air Force. These were kept flying until 1951 when they were replaced in service by more advanced jet fighters of Soviet origin. Both versions are on display at the Prague Aviation museum in Kbely.

Flyable reproductions

Reproduction of a Messerschmitt Me 262 in 2006

In January 2003, the American Me 262 Project, based in Everett, Washington, completed flight testing to allow for delivery of near-exact reproductions of several versions of the Me 262 including at least two B-1c two-seater variants, one A-1c single seater and two "convertibles" that could be switched between the A-1c and B-1c configurations. All are powered by General Electric J85 engines and feature additional safety features, such as upgraded brakes and strengthened landing gear. The "c" suffix refers to the new J85 powerplant and has been informally assigned with the approval of the Messerschmitt Foundation in Germany (the Werk Number of the reproductions picked up where the last wartime produced Me 262 left off – a continuous airframe serial number run with a 50 year production break).

Flight testing of the first newly manufactured Me 262 A-1c (single-seat) variant (Werk Number 501244) was completed in August 2005. The first of these machines (Werk Number 501241) went to a private owner in the southwestern United States, while the second (Werk Number 501244) was delivered to the Messerschmitt Foundation at Manching, Germany. This aircraft conducted a private test flight in late April 2006, and made its public debut in May at the ILA 2006. The new Me 262 flew during the public flight demonstrations. Me 262 Werk Number 501241 was delivered to the Collings Foundation as White 1 of JG 7. This aircraft will be offering ride-along flights starting in 2008. The third replica, a non-flyable Me 262 A-1c, was delivered to the Evergreen Aviation & Space Museum in May 2010.
