In early production of a prototype series, known as the Me , began. Three Bf prototypes VV3 were built. It was thought that intelligence services would conclude any reference to the number "" would be for that earlier design.
Ten Me As V4-V13 were built for pilot training and further tests. During testing of the prototype A-series aircraft, the jettisonable undercarriage presented a serious problem.
The original dollies possessed well-sprung independent suspension for each wheel,  and as the aircraft took off, the large springs rebounded and threw the dolly upward, striking the aircraft.
The production B-series aircraft used much simpler, crossbeam-axled dollies, and relied on the landing skid's oleo-pneumatic strut  to absorb ground-running impacts during the takeoff run, as well as to absorb the shock of landing.
If the hydraulic cylinder was malfunctioning, or the skid mistakenly left during a landing procedure in the "locked and lowered" position as it had to be for takeoff , the impact of a hard touchdown on the skid could cause back injuries to the pilot.
Once on the ground, the aircraft had to be retrieved by a Scheuch-Schlepper , a converted small agricultural vehicle,  originally based on the concept of the two-wheel tractor , carrying a detachable third swiveling wheel at the extreme rear of its design for stability in normal use—this swiveling third wheel was replaced with a pivoting, special retrieval trailer that rolled on a pair of short, triple-wheeled continuous track setups one per side for military service wherever the Komet was based.
This retrieval trailer usually possessed twin trailing lifting arms, that lifted the stationary aircraft off the ground from under each wing whenever it was not already on its twin-wheel dolly main gear, as when the aircraft had landed on its ventral skid and tailwheel after a mission.
During flight testing, the superior gliding capability of the Komet proved detrimental to safe landing. As the now un-powered aircraft completed its final descent, it could rise back into the air with the slightest updraft.
Since the approach was unpowered, there was no opportunity to make another landing pass. For production models, a set of landing flaps allowed somewhat more controlled landings.
This issue remained a problem throughout the program. Development of an operational version was given the highest priority.
In December , work on an upgraded design began. A simplified construction format for the airframe was deemed necessary, as the Me A version was not truly optimized for large-scale production.
The result was the Me B subtype, which had the desired, more mass-producible fuselage, wing panel, retractable landing skid and tailwheel designs with the previously mentioned unsprung dolly takeoff gear, and a generally one-piece conical nose for the forward fuselage which could incorporate a turbine for supplementary electrical power while in flight, as well as a one-piece, perimeter frame-only hinged canopy [ clarification needed ] for ease of production.
Meanwhile, Walter had started work on the newer HWK bipropellant hot engine , which added a true fuel of hydrazine hydrate and methanol , designated C-Stoff , that burned with the oxygen-rich exhaust from the T-Stoff , used as the oxidizer, for added thrust see: List of Stoffs.
The new powerplant and numerous detail design changes meant to simplify production over the general A-series airframe design resulted in the significantly modified Me B of late Due to the Reichsluftfahrtministerium requirement that it should be possible to throttle the engine, the original power plant grew complicated and lost reliability.
The fuel system was particularly troublesome, as leaks incurred during hard landings easily caused fires and explosions.
Metal fuel lines and fittings, which failed in unpredictable ways, were used as this was the best technology available.
Both fuel and oxidizer were toxic and required extreme care when loading in the aircraft, yet there were occasions when Komets exploded on the tarmac from the propellants' hypergolic nature.
For safety purposes, it left the immediate area of the aircraft following its delivery and capping off of the Komet ' s fuel tanks from a rear located dorsal fuselage filling point just ahead of the Komet ' s vertical stabilizer.
Then, the other tanker truck carrying the very reactive T-Stoff hydrogen peroxide oxidizer would deliver its load through a different filling point on the Komet ' s dorsal fuselage surface, located not far behind the rear edge of the canopy.
The corrosive nature of the liquids, especially for the T-Stoff oxidizer, required special protective gear for the pilots. To help prevent explosions, the engine and the propellant storage and delivery systems were frequently and thoroughly hosed down and flushed with water run through the propellant tanks and the rocket engine's propellant systems before and after flights, to clean out any remnants.
Early in the war, when German aircraft firms created versions of their aircraft for export purposes, the a was added to export ausland variants B-1a or to foreign-built variants Ba-1 but for the Me , there were neither export nor a foreign-built version.
As the Me was planned with  an alternative BMW PA rocket engine, it is likely the "a" was used for this purpose on early examples.
Only one Me , the V10, was tested with the BMW engine, so this designation suffix was soon dropped. The Me B had very docile landing characteristics, mostly due to its integrated leading edge slots , located directly forward of the elevon control surfaces, and just behind and at the same angle as the wing's leading edge.
It would neither stall nor spin. One could fly the Komet with the stick full back, and have it in a turn and then use the rudder to take it out of the turn, and not fear it snapping into a spin.
It would also slip well. Because the Me B's airframe design was derived from glider design concepts, it had excellent gliding qualities, and the tendency to continue flying above the ground due to ground effect.
On the other hand, making a too close turn from base onto final, the sink rate would increase, and one could quickly lose altitude and come in short.
Another main difference from a propeller-driven aircraft is that there was no slipstream over the rudder.
Pilots accustomed to flying propeller-driven aircraft had to be careful that the control stick was not somewhere in the corner when the control surfaces began working.
These, like many other specific Me problems, would be resolved by specific training. The performance of the Me far exceeded that of contemporary piston engine fighters.
The usable Mach number was similar to that of the Me , but because of the high thrust-to-drag ratio, it was much easier for the pilot to lose track of the onset of severe compressibility and risk loss of control.
A Mach warning system was installed as a result. The aircraft was remarkably agile and docile to fly at high speed. According to Rudolf Opitz, chief test pilot of the Me , it could "fly circles around any other fighter of its time".
By this point, Messerschmitt was completely overloaded with production of the Messerschmitt Bf and attempts to bring the Me into service.
Production in a dispersed network was handed over to Klemm, but quality control problems were such that the work was later given to Junkers, who were, at that time, underworked.
As with many German designs of World War II's later years, parts of the airframe especially the wings were made of wood by furniture manufacturers.
The older Me A and first Me B prototypes were used for training. It was planned to introduce the Me S , which removed the rocket engine and tank capacity and placed a second seat for the instructor above and behind the pilot, with his own canopy.
The Me S would be used for glider landing training, which as explained above, was essential to operate the Me It appears the Ss were converted from the earlier Me B series prototypes.
In service, the Me turned out to be difficult to use against enemy aircraft. Its tremendous speed and climb rate meant a target was reached and passed in a matter of seconds.
Although the Me was a stable gun platform, it required excellent marksmanship to bring down an enemy bomber.
Four or five hits were typically needed to take down a B Innovative methods were employed to help pilots achieve kills. The most promising was a weapon called the Sondergerät Jägerfaust.
Five were mounted in the wing roots on each side of the aircraft. A photocell in the upper surface of the Komet triggered the weapons by detecting the change in brightness when the aircraft flew under a bomber.
As each shell shot upwards, the disposable gun barrel that fired it was ejected downwards, thus making the weapon recoilless.
It appears that this weapon was used in combat only once, resulting in the destruction of a Lancaster bomber on 10 April The biggest concern about the design was the short flight time, which never met the projections made by Walter.
With only seven and a half minutes of powered flight, the fighter truly was a dedicated point defense interceptor. To improve this, the Walter firm began developing two more advanced versions of the A rocket engine, the B and C, each with two separate combustion chambers of differing sizes, one above the other, for greater efficiency.
They were tuned for high power for takeoff and climb. Two Bs, models V6 and V18, were experimentally fitted with the lower-thrust B-version of the new twin-chamber engine mandating twin combustion chamber pressure gauges on the instrument panel  of any Komet equipped with them , a retractable tailwheel, and tested in spring The main combustion chamber of the B engine used for the B V6 and V18 occupied the same location as the A-series' engine did, with the lower Marschofen cruise chamber housed within the retractable tailwheel's appropriately widened ventral tail fairing.
The X-1 never exceeded Dittmar's speed from a normal runway " scharfer Start " liftoff. Waldemar Voigt of Messerschmitt's Oberammergau project and development offices started a redesign of the to incorporate the new twin-chamber Walter rocket engine, as well as fix other problems.
The resulting Me C design featured a larger wing through the addition of an insert at the wing root, an extended fuselage with extra tank capacity through the addition of a plug insert behind the wing, a ventral fairing whose aft section possessed a retractable tailwheel design closely resembling that pioneered on the Me B V6, and a new pressurized cockpit topped with a bubble canopy for improved visibility, on a fuselage that had dispensed with the earlier B-version's dorsal fairing.
By this time the project was moved to Junkers. There, a new design effort under the direction of Heinrich Hertel at Dessau attempted to improve the Komet.
The Hertel team had to compete with the Lippisch team and their Me C. Hertel investigated the Me and found it was not well suited for mass production and not optimized as a fighter aircraft, with the most glaring deficiency being the lack of retractable landing gear.
To accommodate this, what would eventually become the Me V1 prototype would be fitted with the desired tricycle gear, also accommodating the twin-chamber Walter rocket from the start—later it was assigned to the Ju program.
The resulting Junkers Ju used a three-section fuselage to ease construction. The V1 prototype was completed for testing in August , and was glider-tested behind a Junkers Ju Some sources state that the Walter —C engine was fitted in September, but it was probably never tested under power.
This appears to have been a formality only, with Junkers continuing the work and planning production. While it did not reach operational status, the work was briefly continued by the Soviet Mikoyan-Gurevich MiG design bureau as the Mikoyan-Gurevich I The initial test deployment of the Me A, 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 , receiving their eight A-model service test aircraft by July 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 , 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 to August As EK 16 commenced small-scale combat operations with the Me B in May , the Me B'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.

On 7 October the raider, disguised as a minesweeper , departed from the Dutch-occupied port of Vlissingen with the objective to reach the Atlantic Ocean.
Initial attempts by the Royal Navy to attack the ship in the Straits of Dover had failed. On 13 October, Komet sailed from Le Havre with an escort of 4 or 5 torpedo boats.
These 3 groups headed for a position near Cap de la Hague. The German convoy were spotted by a Coastal Command aircraft in the middle of the Baie de la Seine , travelling at 16 knots, and groups A C and D hurried to get into position.
In the particularly dark night and moderately rough sea conditions, the MTB flotillas became separated from the destroyers. At just before am, Cottesmore sighted the German vessels.
The allied ships fired star shells to illuminate the target and then opened fire. To the British attackers, the Germans appeared taken completely by surprise and in the confusion, opened fire on each other, until eventually firing torpedoes at the allied ships all of which missed.
Two of the escorts were on fire and the other German ships turned inshore to gain the protection of the coastal artillery batteries.
As junior, Drayson was last in the line of MTBs and became separated from the rest of the flotilla as they crossed the Channel.
Drayson continued independently to Cap de La Hague. None of the other allied MTBs arrived in the area. After a while, Drayson saw star shells and tracer as the battle started and increased speed.
He decided to approach the action from the shoreward side to catch any German vessel trying to get away. This put MTB in position to see Komet illuminated by a star shell.
The German ship was travelling at more than 15 knots, exchanging fire with the allied destroyers who were in pursuit. Drayson's MTB was ahead of the German ship and crept in at slow speed to fire 2 torpedoes at a range of yards.
MTB immediately turned away and "crash-started" her main engines to escape under cover of a smoke-screen. Komet had now sighted her and switched fire.
Within a few seconds, the 2 torpedoes struck, followed by a huge secondary explosion. The force of this blast lifted the stern of MTB out of the water and put out of action 2 of the boat's 3 engines, leaving her to return home at reduced speed.
Group B had moved to join the battle and engaged some of the remaining German vessels, but with the main target gone and shore battery fire now becoming more accurate, broke off the action and returned home.
Komet sank with no survivors. The allied forces experienced only 2 minor casualties, despite being under heavy fire.
