The Messerschmitt Me 163 Komet is a rocket-powered interceptor aircraft primarily designed and produced by the German aircraft manufacturer Messerschmitt. It is the only operational rocket-powered fighter aircraft in history as well as the first piloted aircraft of any type to exceed 1,000 kilometres per hour (620 mph) in level flight.

Development of what would become the Me 163 can be traced back to 1937 and the work of the German aeronautical engineer Alexander Lippisch and the Deutsche Forschungsanstalt für Segelflug (DFS). Initially an experimental programme that drew upon traditional glider designs while integrating various new innovations such as the rocket engine, the development ran into organisational issues until Lippisch and his team were transferred to Messerschmitt in January 1939. Plans for a propeller-powered intermediary aircraft were quickly dropped in favour of proceeding directly to rocket propulsion. On 1 September 1941, the prototype performed its maiden flight, quickly demonstrating its unprecedented performance and the qualities of its design. Having been suitably impressed, Nazi officials quickly enacted plans that aimed for the widespread introduction of Me 163 point-defence interceptors across Germany. During December 1941, work began on the upgraded Me 163B, which was optimized for large-scale production.

During early July 1944, German test pilot Heini Dittmar reached 1,130 km/h (700 mph), an unofficial flight airspeed record that remained unmatched by turbojet-powered aircraft up until 1953. That same year, the Me 163 began flying operational missions, being typically used to defend against incoming enemy bombing raids. As part of their alliance with Empire of Japan, Germany provided design schematics and a single Me 163 to the country; this led to the development of the Mitsubishi J8M. By the end of the conflict, roughly 370 Komets had been completed, most of which were being used operationally. However, some of the aircraft's shortcomings were never addressed, and the type was not as effective in combat as had been hoped. Being only capable of a maximum of seven and a half minutes of powered flight, its range fell short of projections and greatly limited its potential. Efforts to improve the aircraft were made (most notably the development of the Messerschmitt Me 263), but many of these did not see actual combat due to the sustained advancement of the Allied powers into Germany in 1945.

For a dedicated interceptor aircraft that achieved operational status, the track record of the Me 163 is somewhat underwhelming, having been credited with the destruction of between nine and 18 Allied aircraft against ten losses. Aside from the actual combat losses incurred, numerous Me 163 pilots had been killed during testing and training flights. This high loss rate was, at least partially, a result of the later models' use of rocket propellant, which was not only highly volatile but also corrosive and hazardous to be around. One noteworthy fatality was that of Josef Pöhs, a German fighter ace and Oberleutnant in the Luftwaffe, who was killed in 1943 through exposure to T-Stoff in combination with injuries sustained during a failed takeoff that ruptured a fuel line. Besides Nazi Germany, no nation has ever made operational use of either the Me 163 specifically, or rocket planes in general; however, a few captured Me 163s were flown for evaluation and research purposes.

Operational history

The initial test deployment of the Me 163A, to acquaint prospective pilots with the world's first rocket-powered fighter, occurred with Erprobungskommando 16 (Service Test Unit 16, EK 16), led by Major Wolfgang Späte and first established in late 1942, receiving their eight A-model service test aircraft by July 1943. Their initial base was as the Erprobungsstelle (test facility) at the Peenemünde-West field. They departed permanently the day after an RAF bombing raid on the area on 17 August 1943, moving southwards, to the base at Anklam, near the Baltic coast. Their stay was brief, as a few weeks later they were placed in northwest Germany, based at the military airfield at Bad Zwischenahn from August 1943 to August 1944. EK 16 received their first B-series armed Komets in January 1944, and was ready for action by May while at Bad Zwischenahn. Major Späte flew the first-ever Me 163B combat sortie on 13 May 1944 from the Bad Zwischenahn base, with the Me 163B armed prototype (V41), bearing the Stammkennzeichen PK+QL.

As EK 16 commenced small-scale combat operations with the Me 163B in May 1944, the Me 163B's unsurpassed velocity was something Allied fighter pilots were at a loss to counter. The Komets attacked singly or in pairs, often even faster than the intercepting fighters could dive. A typical Me 163 tactic was to fly vertically upward through the bombers at 9,000 m (30,000 ft), climb to 10,700–12,000 m (35,100–39,400 ft), then dive through the formation again, firing as they went. This approach afforded the pilot two brief chances to fire a few rounds from his cannons before gliding back to his airfield. The pilots reported it was possible to make four passes on a bomber, but only if it was flying alone. According to the historian Mano Ziegler, Nazi officials were allegedly considering using the Me 163 to directly ram into enemy aircraft; this desperate tactic was never actually used. During early 1944, routine aerial reconnaissance flights over German aerodromes had made the Allies aware of the existence of the Me 163.

Glider pilots were the preferred trainees, using the Stummelhabicht, with a 6-metre (20 ft) wingspan, to mimic the handling characteristics of the Me 163. Training included gunnery practice with a machine pistol mounted in the glider nose. As the cockpit was unpressurized, the operational ceiling was limited by what the pilot could endure for several minutes while breathing oxygen from a mask, without losing consciousness. Pilots underwent altitude chamber training to harden them against the rigors of operating in the thin air of the stratosphere without a pressure suit. Special low fiber diets were prepared for pilots, as gas in the gastrointestinal tract would expand rapidly during ascent.

Following the initial combat trial missions of the Me 163B with EK 16, during the winter and spring of 1944 Major Späte formed the Luftwaffe's first dedicated Me 163 fighter wing, Jagdgeschwader 400 (JG 400), in Brandis, near Leipzig. JG 400's purpose was to provide additional protection for the Leuna synthetic gasoline works which were raided frequently during almost all of 1944. A further group was stationed at Stargard near Stettin to protect the large synthetic fuel plant at Pölitz (today Police, Poland). Further defensive units of rocket fighters were planned for Berlin, the Ruhr, and the German Bight.

The first actions involving the Me 163B in regular Luftwaffe active service occurred on 28 July 1944, from I./JG 400's base at Brandis, when two USAAF B-17 Flying Fortress were attacked without confirmed kills. Combat operations continued from May 1944 to spring 1945. During this time, there were nine confirmed kills with ten Me 163s lost. Feldwebel Siegfried Schubert was the most successful pilot, with three bombers to his credit. Each engagement would see as many as a dozen Me 163s at a time launched to challenge the B-17s.

Allied fighter pilots quickly observed the short duration of the Me 163's powered flight, and adapted their tactics to take advantage of this. The fighters would delay engaging until after the engine had exhausted its propellant before pouncing on the unpowered Komet. Even with this handicap, the aircraft was extremely manoeuvrable in gliding flight and thus was not a straightforward target to down. Another Allied method of engagement was attack the airfields from which the Komets operated, performing strafing runs upon them after the Me 163s had landed. Due to the skid-based landing gear system, the Komet was immobile until the Scheuch-Schlepper tractor could back the trailer up to the nose of the aircraft, place its two rear arms under the wing panels, and jack up the trailer's arms to hoist the aircraft off the ground or place it back on its take-off dolly to tow it back to its maintenance area.

At the end of 1944, 91 aircraft had been delivered to JG 400, but a persistent lack of fuel had kept most of them grounded. It was clear that the original plan for a huge network of Me 163 bases would never be realized. Up to that point, JG 400 had lost only six aircraft due to enemy action. Nine Me 163s had been lost to other causes, remarkably few for such a revolutionary and technologically advanced aircraft. Into early 1945, the type continued to be flown to defend high priority targets, such as the Daimler Benz tank factory in Berlin. In the final days of Nazi Germany, the Me 163 was given up in favor of the more successful Me 262. At the beginning of May 1945, Me 163 operations were stopped, the JG 400 disbanded, and many of its pilots sent to fly Me 262s.

In any operational sense, the Komet was a failure. Although it shot down sixteen aircraft, mainly four-engined bombers, it did not warrant the effort put into the project. Due to fuel shortages late in the war, few went into combat, and it took an experienced pilot with excellent shooting skills to achieve kills. The Komet also spawned later weapons like the vertical-launch, similarly rocket-powered Bachem Ba 349 Natter, and the postwar, American turbojet-powered Convair XF-92 delta wing interceptor. Ultimately, the point defense role that the Me 163 played would be taken over by the surface-to-air missile (SAM), Messerschmitt's own example being the Enzian.

Postwar flight

Captain Eric Brown RN, Chief Naval Test Pilot and commanding officer of the Captured Enemy Aircraft Flight, who tested the Me 163 at the Royal Aircraft Establishment (RAE) at Farnborough, said, "The Me 163 was an aeroplane that you could not afford to just step into the aircraft and say 'You know, I'm going to fly it to the limit.' You had very much to familiarise yourself with it because it was state-of-the-art and the technology used." Acting unofficially, after a spate of accidents involving Allied personnel flying captured German aircraft resulted in official disapproval of such flights, Brown was determined to fly a powered Komet. On around 17 May 1945, he flew an Me 163B at Husum with the help of a cooperative German ground crew, after initial towed flights in an Me 163A to familiarise himself with the handling.

The day before the flight, Brown and his ground crew had performed an engine run on the chosen Me 163B to ensure that everything was running correctly, the German crew being apprehensive should an accident befall Brown, until being given a disclaimer signed by him to the effect that they were acting under his orders. On the rocket-powered "scharfer-start" takeoff the next day, after dropping the takeoff dolly and retracting the skid, Brown later described the resultant climb as "like being in charge of a runaway train", the aircraft reaching 32,000 ft (9.76 km) altitude in 2 minutes, 45 seconds. During the flight, while practicing attacking passes at an American B-17 bomber, he was surprised at how well the Komet accelerated in the dive with the engine shut down. When the flight was over Brown had no problems on the approach to the airfield; apart from the rather restricted view from the cockpit due to the flat angle of glide, the aircraft touching down at 200 km/h (120 mph). Once down safely, Brown and his much-relieved ground crew celebrated with a drink.

Beyond Brown's unauthorised flight, the British never tested the Me 163 under power themselves; due to the danger of its hypergolic propellants it was only flown unpowered. Brown himself piloted RAE's Komet VF241 on a number of occasions, the rocket motor being replaced with test instrumentation. When interviewed for a 1990s television programme, Brown said he had flown five tailless aircraft in his career (including the British de Havilland DH 108). Referring to the Komet, he said "this is the only one that had good flight characteristics".

Surviving aircraft

It has been claimed that at least 29 Komets were shipped out of Germany after the war and that of those at least 10 have been known to survive the war to be put on display in museums around the world. Most of the 10 surviving Me 163s were part of JG 400, and were captured by the British at Husum, the squadron's base at the time of Germany's surrender in 1945. According to the RAF museum, 48 aircraft were captured intact and 24 were shipped to the United Kingdom for evaluation, although only one, VF241, was test flown (unpowered).

Australia

  • Me 163B, Werknummer 191907 was part of JG 400, captured at Husum and was shipped to the RAE. It was allocated the RAF Air Ministry number of AM222 and was dispatched from Farnborough to No. 6 MU, RAF Brize Norton, on 8 August 1945. On 21 March 1946, it was recorded in the Census of No. 6 MU, and allocated to No. 76 MU (Wroughton) on 30 April 1946 for shipment to Australia. For many years this aircraft was displayed at RAAF Williams Point Cook, but in 1986, the Me 163 was transferred to The Australian War Memorial for refurbishment. It was stored at the AWM Treloar Technology Annex Mitchell, refurbished and reassembled, and was later put up for display together with a Messerschmitt Me 262A-2a, Werknummer 500200 (AM81).

Canada

  • Me 163B, Werknummer 191659 (AM215) or 191914 (AM220), is held at the Canada Aviation and Space Museum, Ottawa. Like two of the British Komets, this aircraft was part of JG 400 and captured at Husum. It was shipped to Canada in 1946.
Werknummer 19116 (but more probable 191916) and 191095 (AM211) also seem to have been held at one time in this museum.

Germany

  • A Me 163B, Werknummer 191904, "Yellow 25", belonging to JG 400 was captured by the RAF at Husum in 1945. It was sent to England, arriving first at Farnborough, receiving the RAF Air Ministry number AM219 and then transferred to Brize Norton on 8 August 1945, before finally being placed on display at the Station Museum at Colerne. When the museum closed in 1975 the aircraft went to RAF St Athan, receiving the ground maintenance number 8480M. On 5 May 1988 the aircraft was returned to the Bundeswehr's Luftwaffe air arm, and moved to the Luftwaffe Alpha Jet factory at the air base in Oldenburg (JBG 43), not far from the JG 400 unit's wartime base at Bad Zwischenahn, now a golf course. The airframe was in good condition but the cockpit had been stripped and the rocket engine was missing.

Eventually an elderly German woman came forward with Me 163 instruments that her late husband had collected after the war, and the engine was reproduced by a machine shop owned by Me 163 enthusiast Reinhold Opitz. The factory closed in the early 1990s and "Yellow 25" was moved to a small museum created on the site. The museum contained aircraft that had once served as gate guards, monuments and other damaged aircraft previously located on the air base. In 1997 "Yellow 25" was moved to the official Luftwaffe Museum located at the former RAF base at Berlin-Gatow, where it is displayed today alongside a restored Walter HWK 109–509 rocket engine. This particular Me 163B is one of the very few World War II–era German military aircraft, restored and preserved in a German aviation museum, to have a swastika marking, in a "low visibility" white outline form, currently displayed on the tailfin.

  • Me 163B, Werknummer 120370, "Yellow 6" of JG 400, is displayed at the Deutsches Museum, Munich. It was originally sent to Britain, where it had received the RAF Air Ministry number AM210. It was given to the Deutsches Museum by RAF Biggin Hill Station. Some claim this is 191316, but that is still at the London Science Museum.

United Kingdom

Of the 21 aircraft that were captured by the British, at least three have survived. They were assigned the British serial numbers AM200 to AM220.

  • Me 163B, Werknummer 191316, "Yellow 6", has been on display at the Science Museum in London, since 1964 with the Walter motor removed for separate display. A second Walter motor and a takeoff dolly are part of the museum's reserve collection and are not generally on display to the public.
  • Me 163B, Werknummer 191614, is now displayed at the RAF Museum London, where it was moved from the RAF Museum Cosford site at RAF Cosford, its former home since 1975. Before then, it was at the Rocket Propulsion Establishment at Westcott, Buckinghamshire. This aircraft last flew on 22 April 1945, when it shot down an RAF Lancaster.
  • Me 163B-1a, Werknummer 191659 and RAF Air Ministry serial number AM215, "Yellow 15", was captured at Husum in 1945 and was sent to the College of Aeronautics at Cranfield, England in 1947. After many years of touring airshows and various outdoor gatherings around the UK it was loaned to the National Museum of Flight at East Fortune Airfield, East Lothian, Scotland in 1976.

  • Five Me 163s were originally brought to the United States in 1945, receiving the Foreign Equipment numbers FE-495 and FE-500 to 503. An Me 163 B-1a, Werknummer (serial number) 191301, arrived at Freeman Field, Indiana, during mid-1945, and received the foreign equipment number FE-500. On 12 April 1946, it was flown aboard a cargo aircraft to the U.S. Army Air Forces facility at Muroc dry lake in California for flight testing. Testing began on 3 May 1946 in the presence of Dr. Alexander Lippisch and involved towing the unfueled Komet behind a Boeing B-29 Superfortress to an altitude of 9,000–10,500 m (29,500–34,400 ft) before it was released for a glide back to earth under the control of test pilot Major Gus Lundquist. Powered tests were planned, but not carried out after delamination of the aircraft's wooden wings was discovered. It was then stored at Norton AFB, California until 1954, when it was transferred to the Smithsonian Institution. The aircraft remained on display in an unrestored condition at the museum's Paul E. Garber Preservation, Restoration, and Storage Facility in Suitland, Maryland, until 1996, when it was lent to the Mighty Eighth Air Force Museum in Pooler, Georgia for restoration and display but has since been returned to the Smithsonian and as of 2011 is on display unrestored at the National Air and Space Museum's Steven F. Udvar-Hazy Center near Washington D.C.
  • Me 163B, Werknummer 191 095, is on fully restored display at the National Museum of the United States Air Force at Wright-Patterson AFB near Dayton, Ohio. It was acquired from the Canadian National Aviation Museum (now the Canada Aviation and Space Museum), where it had been restored, and was placed on display 10 December 1999. Komet test pilot Rudolf "Rudi" Opitz [de] was on hand for the dedication of the aircraft and discussed his experiences of flying the rocket-propelled fighter to a standing room only crowd. During the aircraft's restoration in Canada it was discovered that the aircraft had been assembled by French forced laborers who had deliberately sabotaged it by placing stones between the rocket's fuel tanks and its supporting straps. There are also indications that the wing was assembled with contaminated glue. Patriotic French writing was found inside the fuselage. The aircraft is displayed without any unit identification, but has its Werknummer restored to its normal fin location. Fully restored examples of both the Me 163B's single-chamber rocket motor, as well as the only known example in the United States of the experimental twin-chamber Walter "509B" rocket motor, are each on display in front, one each to either side, of WkNr. 191 095.
  • Me 163B, Werknummer 191660, "Yellow 3", is owned by Paul Allen's Flying Heritage Collection. Between 1961 and 1976, this aircraft was displayed at the Imperial War Museum in London. In 1976, it was moved to the Imperial War Museum Duxford. It underwent a lengthy restoration, beginning in 1997, that was frequently halted as the restorers were diverted to more pressing projects. In May 2005, it was sold, reportedly for £800,000, to raise money for the purchase of a de Havilland/Airco DH.9 as the Duxford museum had no examples of a World War I bomber in its collection. Permission for export was granted by the British government's Department for Culture, Media and Sport as three other Komets were held in British museums.

Japanese versions

As part of their alliance, Germany provided the Japanese Empire with plans and an example of the Me 163. One of the two submarines carrying Me 163 parts did not arrive in Japan, so at the time, the Japanese lacked all of the major parts and construction blueprints, including the turbopump, which they could not make themselves, forcing them to reverse-engineer their own design from information obtained in the Me 163 Erection & Maintenance manual obtained from Germany. The prototype J8M crashed on its first powered flight and was completely destroyed, but several variants were built and flown, including: trainers, fighters, and interceptors, with only minor differences between the versions.

The Navy version, the Mitsubishi J8M1 Shūsui, replaced the Ho 155 cannon with the Navy's 30 mm (1.18 in) Type 5. Mitsubishi also planned on producing a version of the 163C for the Navy, known as the J8M2 Shūsui Model 21. A version of the 163 D/263 was known as the J8M3 Shusui for the Navy with the Type 5 cannon, and a Ki-202 Shūsui-kai (秋水改, "Autumn Water, modified") with the Ho 155-II for the Army. Trainers were planned, roughly the equivalent of the Me 163 A-0/S; these were known as the Kugisho/Yokosuka MXY8 (Yokoi Ki-13) Akigusa (秋草, "Autumn Grass") (an unpowered glider trainer) and Kugisho/Yokosuka MXY9 Shūka (秋花, "Autumn Flower") (a Tsu-11-powered motorjet trainer).

One complete example of the Japanese aircraft survives at the Planes of Fame Air Museum in California. The fuselage of a second aircraft is displayed at the Mitsubishi company's Komaki Plant Museum, at Komaki, Aichi in Japan.

Replicas

A flying replica Me 163 was constructed between 1994 and 1996 by Joseph Kurtz, a former Luftwaffe pilot who trained to fly Me 163s, but who never flew in combat. He subsequently sold the aircraft to EADS. The replica is an unpowered glider whose shape matches that of an Me 163, although its construction is completely different: the glider is built of wood with an empty weight of 285 kilograms (628 lb), a fraction of the weight of a wartime aircraft. Reportedly, it has excellent flying characteristics. The glider is painted red to represent the Me 163 flown by Wolfgang Späte. As of 2011, it was still flying with the civil registration D-1636.

In the early 2000s, a rocket-powered airworthy replica, the Komet II, was proposed by XCOR Aerospace, a former aerospace company that had previously built the XCOR EZ-Rocket rocket-plane. Although outwardly the same as a wartime aircraft, the Komet II's design would have differed considerably for safety reasons. It would have been partially constructed with composite materials, powered by one of XCOR's own simpler and safer, pressure fed, liquid oxygen/alcohol engines, and retractable undercarriage would have been used instead of a takeoff dolly and landing skid.

Several static replica Me 163s are exhibited in museums.
