Anybody know about what year this plane was actually produced & photographed for Gobbels propaganda?

12-17-2005, 10:29 PM
38-39 at a guess? it was prewar i think

12-17-2005, 10:32 PM
Pre war for sure. However Romanians used HE-112 in ww2 on Eastern front as well.
Actuall that aircrafts were promising much but in some stage they were abandoned in favour of Bf-109 as Luftwaffe mainstay fighter.

The first prototype He 100 V1 flew in January, 1938.

In 1940 Joseph Goebbels began to publicize a new fighter that he claimed was entering service with the Luftwaffe. Pictures of Heinkel He 100D-1's were taken and given the name " He 113 ".

Very good now insert KI-61 into DCG 1939 LW campaign with HE100 scheme downloaded from flying legends & dont feel guilty (I know that is an insane explanation, why feel this way about a sim, I dont know maybe a shrink can tell me)

Some pics of Romanian He 112

Hmm...that would be a rahter nice plane to have, manouverable, and hard hitting with those 20mm cannons. Even if not that fast, it would be fun for DF furballs.

12-18-2005, 07:42 AM
A Spanish He112 even shot up a P-38 enough to force it to crashland.

bad idea

apart from looks, these two types are very different in performance

100 had higher wingloading than 109
61 can handily outturn 109s, by a large margin
100 had much higher speed than 61 as well

AFAIK, the 100 was much, much faster than the 109, and with higher wingloading, maiking it not-so-manuverable (at least compared to 109)

the type that SHOULD have kept the 109 out of production

12-18-2005, 10:28 AM
Wingloading of He100D0 and Yak 3 is comparable, speed too...

Granted, but its a sim & not reality, so we have the ability to do whatever we want,so if your sick & tired of flying 109Es you have a choise, that is the beauty of DCG.

this is the 3D model that was made before FB's release

How the """ could they not release that? Its really nice.

maybe just to let down punkass "wannabe" nazi racists ?

it wasnt MG staff that made that model

12-18-2005, 11:36 PM
Mr. Heinkel was very disapointed that his fighter was beaten by the 109, but the dozen or so 100s (alot different from 112 it seems) were used for defense of the main He factory. the allies thought they were in prodution, and there were kills claimed against these planes pretty often.

some of my dad's many WW2 model airplane news, air trails, and other aviation magazines have mentions about these planes in combat, and storys about pilots and gunners shooting them down. Theres an add of some sort in one of them that has a cartoon B17 waste gunner about to engage 3 of them and yelling "2 heinkels at 3 oclock!" The german propaganda effort was very successful.

12-21-2005, 07:30 AM
I wonder how potential of armament upgrade could have the He-100/He-112 compared with the BF-109 on 1941/42.
By that time F and up to G-2 versions was equiped with 1x 20mm cannon and 2x 7.7mm mg wich was the same of the He-100.
Until 1943 the BF-109 did not received MG-131.

And your problem is... ????
As stated above the Romanian AF used this type early in the war ... and i wanted to fly this bird ... dose that make me a nazi ???

12-21-2005, 10:01 AM
Romanian AF did not use He-100.They used the He-112, which is a completely different plane.

12-21-2005, 10:32 AM
I undestatnd why Oleg did't model He100. It would be more uber then anyuthing else. Just imagine Yak 3 in 1940 planeset! Max speed was about 665 km/h, while Be109E had 560km/h and Hurri 520km/h! And maneurability would be also very good (and not heavy elevator). The only shortcoming was rather light weaponry (1xMG/ with 55 rounds and 2x MG17)...

12-21-2005, 10:39 AM
If i remember right there were many problems with this plane. And some of my readings state it wasnt any better then a 109 (maybe marginally, but not enough to claim it as an uberplane for 40). They were much more expensive to build and maintain. Along with the problems and cost the 109 was selected because if you have to build en mass in a hurry a problimatic costly fighter isnt the way to go.

12-21-2005, 11:48 AM
You are wrong, be sure.
He100 was very simple to build, max. speed was 668km/h at 6400m, 560 at 0m, range 900 km (Bf109 had only 560 km). He100D1 had no significant problems and in 1940 would be ready for service.
Maybe you meant He112?

The Heinkel He 100 was a pre-World War II fighter aircraft design from Heinkel. Although it proved to be the fastest fighter in the world at the time, the design was not ordered into production, due largely to the Luftwaffe considering the Messerschmitt Bf 109 to be "good enough" and a serious shortage of engines making production of two similar aircraft out of the question.
Even by early 1936 the RLM became interested in a new fighter that would leap beyond the performance of the Bf 109 as much as the 109 had over the biplanes it replaced. There was never an official project on the part of the RLM, but Roluf Lucht felt that new designs were important enough to ask both Focke-Wulf and Heinkel to provide "super-pursuit" designs for evaluation.

The super-pursuit type was not an official recommendation, so it was possible that Heinkel would be told to stop work on the project by other people in the RLM. Thus the work was kept secret, in a company Memo No.3657 on January 31st this was made clear; The mockup is to be completed by us... as of the beginning of May... and be ready to present to the RLM... and prior to that no one at the RLM is to know of the existence of the mockup.

Walter Günter, one half of the famous Günter brothers, looked at their existing He 112 and decided that nothing more could be done with it. He started over with a completely new design known as Projekt 1035. Learning from past mistakes on the 112 project, the design was to be as easy to build as possible while still offering good performance. That good performance was set at an astounding 700 km/h (435 mph). Keep in mind that fighters with this sort of performance didn't appear on the battlefield until 1944.

To ease production the new design had considerably fewer parts than the 112, and those that remained contained fewer compound curves. P.1035 was made of 969 unique parts and was held together with 11,543 rivets, in comparison the 112 had 2,885 parts and 26,864 rivets. The new straight edged wing was a source of much of the savings, after building the first wings Otto Butter reported that the reduction in complexity and rivet count (along with the Butter brothers's own explosive rivet system) saved an astonishing 1150 man hours per wing.

In order to get the promised performance out of the aircraft, the design included a number of drag reducing features. On the simple end was a well faired cockpit, the absence of struts and other draggy supports on the tail, and fully retractable gear (including the tailwheel) which were completely enclosed in flight. These and similar changes applied to the 109 for the F model would boost performance of that aircraft 50 km/h.

In order to reduce frontal area, the engine was mounted directly to a strong forward fuselage, as opposed to internal struts. The cowling was very tight fitting and as a result the aircraft has something of a slab sided appearance. The design used a shorter wing than the 109, trading altitude and turn performance for speed.

In order to provide as much power as possible from the DB 601 engine, the 100 used exhaust ejectors for a small amount of additional thrust. In addition the supercharger inlet was moved from the normal position on the side of the cowling to a location in the leading edge of the left wing, where the clean airflow improved the ram air effect and increased boost.

For the rest of the designed performance increase, Walter turned to the risky method of cooling the engine via evaporative cooling. In the Heinkel system, designed by Jahn and Jahnke, the engine was run at 110 Celsius and the superheated fluid was then sprayed into the interior of a centrifugal compressor, allowing the pressure to drop and steam to form. The water, being heavier, was forced to the outside of the pump by centrifugal force and returned to the engine. The weight of the water forced the steam into the only available space, the inside of the pump, where it was removed. The steam was then allowed to flow into a series of tubes running on the inside surface of the leading edges of the wings, where it would condense back into water and be pumped back to the engine. A number of pumping systems were tried, and eventually a system of no less than 22 small electric pumps (all with their own failure indicator lamp in the cockpit) was settled on.

Unlike the cooling fluid, oil cannot be allowed to boil. This presents a particular problem with the Daimler-Benz DB 601 series of engines, because of a design technique that results in a considerable amount of heat being transferred to the oil as opposed to the coolant. To cool the oil a small semi retractable radiator was fitted under the wing. This radiator was later replaced on some of the prototypes with a system in which the oil was sent to a heat exchanger where it boiled methyl alcohol to carry away the heat. The alcohol was then cooled in a similar fashion to the engine fluid, by running it to tubes on the top surface of the rear fuselage and leading edge of the vertical stabilizer.

Walter was killed in a car accident on May 25th, 1937, and the design work was taken over by his twin brother Siegfried, who finished the final draft of the design later that year. At the end of October the design was submitted to the RLM, complete with details on prototypes, delivery dates, and prices for three aircraft delivered to the Rechlin test center. At this point the aircraft was being referred to as the He 113, but the "13" in the name was apparently enough to prompt Ernst Heinkel to ask for it to be changed to the He 100.

In November Messerschmitt took the speed record for landplanes in a modified Bf 109. In response Ernst Heinkel made plans to use the He 100 design as a record setting aircraft (less serious plans for this appear to have been in the works all along). Much of the fuselage was as smooth as it could get, so the modifications were limited to the canopy and a newer set of much shorter wings. The racing version would need another airframe, so a fourth prototype was added to the series.

In a December meeting at the Heinkel factory with Ernst Udet and Roluf Lucht the plans were changed slightly. V1 through V3 were to be used for testing and record attempts, V3 sporting the clipped wings. V4 was to a testbed for series production. The RLM went ahead with the plan, due in no small part to Udet's, Minister for Aircraft Production in the RLM, plans to fly the aircraft in a series of record attempts.

The first prototype He 100 V1 flew on January 22nd, 1938, only a week after its promised delivery date. The aircraft proved to be outstandingly fast. However it continued to share a number of problems with the 112, notably a lack of directional stability. In addition the Luftwaffe test pilots disliked the high wing loading, which resulted in landing speeds so great that they often had to use brakes right up to the last 100 m of the runway. The ground crews also disliked the design, complaining about the tight cowling which made servicing the engine difficult. The big problem turned out to be the cooling system, largely to no one's surprise. After a series of test flights V1 was sent to Rechlin in March.

The second prototype addressed the stability problems by changing the vertical stabilizer from a triangular form to a larger and more rectangular form. The oil cooling system continued to be problematic so it was removed and replaced with a small semi retractable radiator below the wing. It also received the still experimental DB 601M engine which the aircraft was originally designed for. The M version was modified to run on "C3" fuel at 96 octane, which would allow it to run at higher power ratings in the future.

V2 was completed in March, but instead of moving to Rechlin it was kept at the factory for an attempt on the 100 km closed circuit speed record. A course was marked out on the Baltic coast between Wustrow and Müritz, 50 km apart, and the attempt was to be made at the aircraft's best altitude of 18000 ft (5,500 m). After some time cleaning out the bugs the record attempt was set to be flown by Captain Herting, who had previously flown the aircraft serveral times.

At this point Ernst Udet showed up and asked to fly V2, after pointing out he had flown the V1 at Rechlin. He took over from Hertingand flew the V2 to a new world 100 km closed circuit record on the 5th of June, 1938, at 634.73 km/h (394.6 mph). Several of the cooling pumps failed on this flight as well, but Udet wasn't sure what the lights meant and simply ignored them.

The record was heavily publicized, but in the press the aircraft was referred to as the "He 112U". Apparently the "U" stood for "Udet". At the time the 112 was still in production and looking for customers, so this was one way to boost sales of the older design. V2 was then moved to Rechlin for continued testing. Later in October the aircraft was damaged on landing when the tail wheel didn't extend, and it is unclear if the damage was repaired.

The V3 prototype received the clipped racing wings, which reduced span and area from 30 ft 10 in (9.4 m) and 155 ft² (14.4 m²), to 24 ft 11 in (7.6 m) and 118.4 ft² (11 m²). The canopy was replaced with a much smaller and more rounded version, and all of the bumps and joints were puttied over and sanded down. The aircraft was equipped with the 601M and flown at the factory.

In August the DB 601R engine arrived from Daimler-Benz and was installed. This version increased the maximum rpm from 2,200 to 3,000, and added methyl alcohol to the fuel mixture to improve cooling in the supercharger and thus increase boost. As a result the output was boosted to 1,776 hp (1,324 kW), although it required constant maintenance and the fuel had to be drained completely after every flight. The aircraft was then moved to Warnemünde for the record attempt in September.

On one of the pre-record test flights by the Heinkel chief pilot, Gerhard Nitschke, the main gear failed to extend and ended up stuck half open. Since the aircraft could not be safely landed it was decided to have Nitschke bail out and let the aircraft crash in a safe spot on the airfield. Gerhard was injured when he hit the tail on the way out, and made no further record attempts.

V4 was to have been the only "production" prototype and was referred to as the "100B" model (V1 through V3 being "A" models). It was completed in the summer and delivered to Rechlin, so it wasn't available for modification into racing trim when V3 crashed. Although the aircraft was unarmed it was otherwise a service model with the 601M, and in testing over the summer it proved to be considerably faster than the 109. At sea level the aircraft could reach 348 mph (560 km/h), faster than the 109E's speed at its best altitude! At 6560 ft it improved to 379 mph (610 km/h), topping out at 416 mph (669 km/h) at 16400 ft before falling again to 398 mph (641 km/h) at 26250 ft. The aircraft had flown a number of times before its landing gear collapsed while standing on the pad on the 22nd of October. The aircraft was later rebuilt and flying by March of 1939.

Although V4 was to have been the last of the prototypes in the original plans, production was allowed to continue with a new series of six aircraft. One of the airframes was selected to replace V3, and as luck would have it V8 was at the "right point" in its construction and was completed out of turn. It first flew on the 1st of December, but this was with a standard DB 601Aa engine. The 601R was then put in the aircraft on the 8th of January 1939, and moved to a new course at Oranienberg. After several shakedown flights, Hans Dieterle flew to a new record on March 30th, 1939, at 746.6 km/h (463.9 mph). Once again the aircraft was referred to as the He 112U in the press. It is unclear when happened to V8 in the end; it may have been used for crash testing.

V5 was completed like V4, and first flew on November 16th. It was later used in a film about V8's record attempt, in order to protect the record breaking aircraft. At this point a number of changes were made to the design resulting in the "100C" model, and with the exception of V8 the rest of the prototypes were all delivered as the C standard.

V6 was first flown in February 1939, and after some test flights at the factory it was flown to Rechlin on the 25th of April. There it spent most of its time as an engine testbed. On the 9th of June the gear failed in-flight, but the pilot managed to land the aircraft with little damage and it was returned to flying condition in six days.

V7 was completed on the 24th of May with a change to the oil cooling system. It was the first to be delivered with armament, consisting of two 20 mm MG/FF in the wings and four 7.92 mm MG17's arranged around the engine cowling. This made the 100 the most heavily armed fighter of its day. V7 was then flown to Rechlin where the armament was removed and the aircraft was used for a series of high speed test flights.

V9 was also completed and armed, but was used solely for crash testing and was "tested to destruction". V10 was originally to suffer a similar fate, but instead ended up being given the racing wings and canopy of the V8 and displayed in the German Museum in Munich as the record€"setting "He 112U". It was later destroyed in a bombing attack.

Overheating problems and general failures with the cooling system motors continued to be a problem. Throughout the testing period failures of the pumps ended flights early, although some of the test pilots simply starting ignoring them. In March Kleinemeyer wrote a memo to Ernst Heinkel about the continuing problems, stating that Schw¤rzler had asked to be put on the problem.

Another problem that was never cured during the prototype stage was a rash of landing gear problems. Although the wide-set gear should have eliminated the gear failures that plagued the 109, the 100's were built very thin and as a result they were no improvement. V2, 3, 4, and 6 were all damaged to various degrees due to various gear failures, a full half of the prototypes.

He 100D-0
Throughout the prototype period the various models were given series designations (as noted above), and presented to the RLM as the basis for series production. The Luftwaffe never took them up on the offer. Heinkel had decided to build a total of 25 of the aircraft one way or the other, so with 10 down there were another 15 of the latest model to go. In keeping with general practice, any series production is started with a limited run of "zero series" machines, and this resulted in the He 100D-0.

The D-0 was similar to the earlier C models, with a few notable changes. Primary among these was a larger vertical tail in order to finally solve the stability issues. In addition the cockpit and canopy were slightly redesigned, with the pilot sitting high in a large canopy with excellent vision in all directions. The armament was reduced from the C model to one 20 mm MG/FF-M in the engine V firing through the propeller spinner, and two 7.92 mm MG17's in the wings close to the fuselage.

The three D-0 aircraft were completed by the summer of 1939 and stayed at the Heinkel Marienehe plant for testing. They were later sold to the Japanese Imperial Navy to serve as pattern aircraft for a production line, and were shipped there in 1940.

He 100D-1
The final evolution of the short He 100 history is the D-1 model. As the name suggests the design was supposed to be very similar to the pre-production D-0's, the main planned change was to enlarge the horizontal stabilizer.

But the big change was the eventual abandonment of the surface cooling system, which proved to be too complex and failure prone. Instead an even larger version of the retractable radiator was installed, and this appeared to completely cure the problems. The radiator was inserted in a "plug" below the cockpit, and as a result the wings were widened slightly.

While the aircraft didn't match its design goal of 700 km/h once it was loaded down with weapons, the larger canopy and the radiator, it was still capable of speeds in the 400 mph (644 km/h) range. A low drag airframe is good for both speed and range, and as a result the He 100 had a combat radius between 900 and 1000 km compared to the 109's 600 km. While not in the same league as the later escort fighters, this was at the time a superb range and may have offset the need for the 110 to some degree.

By this point the war was underway, and as the Luftwaffe would not purchase the aircraft in its current form, the production line was shut down. The remaining twelve He 100D-1c fighters were used to form Heinkel's Marienehe factory defense unit, flown by factory test pilots. They replaced the earlier He 112's that were used for the same purpose, and the 112's were later sold off. At this early stage in the war there were no bombers venturing that far into Germany, and it appears that the unit never saw action. The eventual fate of the D-1's remains unknown. The aircraft were also put to an interesting propaganda/disinformation role, as the supposed Heinkel He 113.

Foreign use
When the war opened in 1939 Heinkel was allowed to look for foreign licensees for the design. Japanese and Soviet delegations visited the Marienehe factory in late October, and were both impressed with what they saw. Thus it was in foreign hands that the 100 finally saw use, although only in terms of adopted design features.

The Soviets were particularly interested in the surface cooling system, and in order to gain experience with it they purchased the six surviving prototypes (V1, V2, V4, V5, V6 and V7). After arriving in the USSR they were passed onto the TsAGI institute for study, there they were analyzed and its features influenced a number of Soviet designs, notably the LaGG-3 and MiG-1. Although the surface cooling system wasn't copied, the addition of larger Soviet engines made up for the difference and the LaGG-3 was a reasonably good performer. It's perhaps ironic that German aircraft would later be shot down by German inspired aircraft.

The Japanese were also looking for new designs, notably those using inline engines where they had little experience. They purchased the three D-0's for 1.2 million DM, as well as a license for production and a set of jigs for another 1.8 million DM. The three D-0's arrived in Japan in May 1940 and were re-assembled at Kasumigaura. They were then delivered to the Japanese Naval Air Force where they were re-named AXHei, for "Experimental Heinkel Fighter". When referring to the German design the aircraft is called both the He 100 and He 113, with at least one set of plans bearing the later name.

In tests the Navy was so impressed that they planned to put the aircraft into production as soon as possible as their land based interceptor €" unlike every other forces in the world, the Army and Navy both fielded complete land based air forces. Hitachi won the contract for the aircraft and started construction of a factory in Chiba for its production. With the war in full swing in Europe however, the jigs and plans never arrived. Why this wasn't sorted out is something of a mystery, and it appears there isn't enough information in the common sources to say for sure what happened.

The DB 601 engine design was far more advanced than any indigenous Japanese design, which tended to concentrate on air cooled radials. To get a jump into the inline field, Kawasaki had already purchased the license for the 601A from Daimler Benz in 1938. The adoption process went smoothly, they adapted it to Japanese tooling and had it in production by late 1940 as the Ha-40.

At the same time Kawasaki was working on two parallel fighter efforts, the Ki-60 heavy fighter and the Ki-61. The former was abandoned after poor test results (the test pilots disliked the high wing loading, as they always did) but work continued on the lightened Ki-61 with the Ha-40 engine. The Ki-61 was clearly influenced by the He 100.

Like the D's it lost the surface cooling system (although an early prototype may have included it), but is otherwise largely similar in design except for changes to the wing and vertical stabilizer. Since the Ki-61 was supposed to be lighter and offer better range than the Ki-60, the design had a longer and more tapered wing for better altitude performance. This also improved the handling to the delight of the test pilots, and the aircraft was put into production. The Hien would prove to be the first of the Japanese aircraft that was truly equal to the contemporary US fighters.

Further developments
In late 1944 the RLM went shopping for a new high altitude fighter with excellent performance. It's unclear exactly why this happened, as the Ta 152H version of the Focke-Wulf Fw 190 was currently in limited production for just this task. Nevertheless Heinkel was contracted to design such an aircraft, and Siegfried Günter was placed in charge of the new Projekt 1076.

The resulting design was similar to the He 100, but many detail changes resulted in an aircraft that looked all new. It sported a new and longer wing for high altitude work, which lost the gull wing bend and was swept forward slightly at eight degrees. Flaps or ailerons spanned the entire trailing edge of the wing giving it a rather modern appearance. The cockpit was pressurized for high altitude flying, and covered with a small bubble canopy that was hinged to the side instead of sliding to the rear. Other changes that seem odd in retrospect is that the gear now retracted outward like the original 109, and he re-introduced the surface cooling system. Planned armament was one 30 mm MK 103 cannon firing through the propeller hub, and two wing mounted 30 mm MK 108 cannons.

The use of one of three different engines was planned: the DB 603M with 1825 hp (1,361 kW), the DB 603N with 2750 hp (2,051 kW) or the Jumo 213E with 1750 hp (1,305 kW). The 603M and 213E both supplied 2100 hp (1,566 kW) using MW-50 water injection. Performance with the 603N was projected to be a shocking 880 km/h (546 mph), which would have stood as a record for many years even when faced with dedicated racing machines. Performance would still be excellent even with the far more likely 2000 hp (1.5 MW) class engines, the 603M was projected to give it the equally amazing speed of 855 km/h (532 mph).

These figures are somewhat suspect though, and are likely just optimistic guesses that could not have been met €" something Heinkel was famous for. Propellers lose efficiency as they approach the speed of sound, and eventually they no longer provide an increase in thrust for an increase in engine power. Even the advanced counter rotating VDM design is unlikely to have been able to effect this problem too much.

The design apparently received low priority, and it was not completed by the end of the war. Siegfried Günter later completed the detailed drawings and plans for the Americans in mid 1945.

In 1939 the He 100 was clearly the most advanced fighter in the world. It was even faster than the Fw 190, and wouldn't be bested until the introduction of the Vought F4U Corsair in 1943. Nevertheless the aircraft was not ordered into production. The reason the He 100 wasn't put into service seems to vary depending on the person telling the story, and picking any one version results in a firestorm of protest.

Some say it was politics that killed the He 100. However this seems to stem primarily from Heinkel's own telling of the story, which in turn seems to be based on some general malaise over the He 112 debacle. The fact is that Heinkel was well respected within the establishment regardless of Messerschmitt's success with the 109 and 110, and this argument seems particularly weak.

Others blame the bizarre production line philosophy of the RLM, which valued huge numbers of single designs over a mix of different aircraft. This too seems somewhat suspect considering that the Fw 190 was purchased shortly after this story ends.

For these reasons it seems safe to accept the RLM version of the story largely at face value; that the production problems with the DB series of engines was so acute that all other designs based on the engine were canceled. At the time the DB 601 engines were being used in both the 109 and 110 aircraft, and Daimler couldn't keep up with those demands alone. The RLM eventually forbade anyone but Messerschmitt to receive any DB 601's, leading to the shelving of many designs from a number of vendors. After all, the 109 and 110 were better than anything out there, so another aircraft that was even better didn't seem important at all.

The only option open to Heinkel was a switch to another engine, and the RLM expressed some interest in purchasing such a version. At the time the only other useful inline was the Junkers Jumo 211, and even that was in short supply. However the design of the He 100 made adaptation to the 211 difficult; both the cooling system and the engine mounts were designed for the 601, and a switch to the 211 would have required a redesign. Heinkel felt it wasn't worth the effort considering the aircraft would end up with inferior performance, and so the He 100 production ends on that sour note.

For this reason more than any other the Focke-Wulf Fw 190 became the next great aircraft of the Luftwaffe, as it was based around the otherwise unused BMW 139 (and later BMW 801) radial engine. Although production of these engines was only starting, the lines for the airframes and aircraft could be geared up in parallel without interrupting production of any existing design. And that's exactly what happened.

There is some disagreement on various measures depending on the source, this appears to be due to the limited number of records left for the aircraft. Common disagreements are on the service ceiling, and the empty weight is also often listed at 1810 kg (3,990 lb). Another issue is the overall height of the aircraft which is sometimes listed at 2.5 m. I believe this is in error in this case, the other common figure of 3.6 m is used because that is likely correct for the enlarged tail of the D-1 models.
Most importantly it should be noted that almost all of the aircraft underwent engine modifications and tweaking during their lifespan. The 650 km/h speed is almost universally quoted for the D-1 models, but it may be the case that this is the speed of the earlier and more slippery V4 "A" model. In general it appears likely that the AIR 40/237 number in the 390 mph (628 kW) range is accurate for the production aircraft.

I'm not sure about He-100, it certainly wouldn't be accepted into service with evaporative surface cooling system, which although eliminated radiator drag, was complicated, delicate & expensive. also I don't think He-100 had much more development potential compared to Bf-109.

Now, FW-187 "Falke" on the other hand (version with conventional cooling) is another story...now that would make BoB interesting if luftwaffe had long range escorts.

Looks pretty too http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Just Do some reading guys! He100D1 had NO evaporating coling system and in 1940 was ready for combat service, but me109 was considered good enough and its serila production was already at full pace. He100D would be an excellent light fighter till 1944!

<span class="ev_code_RED">He 112B in Japanese Service</span>

In 1937 the Japanese Imperial Navy found itself at a disadvantage in combat over the Chinese mainland. The fact that Navy aircraft were fighting over the mainland might seem odd, but interservice rivalry in Japan went beyond the occasional bar brawl and both services fielded complete air forces with their own types of planes.

At the time the Navy air services were small and equipped mostly with older biplanes. Meanwhile the Soviets were supplying the Chinese air forces with the I-15bis and I-16 fighters. Although the new Mitsubishi A5M was largely similar to the I-16, they were just starting to enter service and available in small numbers only. The Navy was concerned about the lack of fighters and went looking for new designs that could be purchased off the shelf to bring the squadrons to strength quickly. At the time the majority of modern design work was taking place in Europe, and with England no longer on friendly terms, they turned to Germany for a new fighter.

In late 1937 a delegation visited the Heinkel plant in Marienehe and saw V9 in action. They were impressed and placed an order for thirty of the B series planes, with an option for 100 more. They even purchased one of the older designs to take back with them immediately (according to the primary source below, this was the V5). Upon arriving in Japan the planes were named A7He1, the A7 refers to the 7th navy fighter design (the Mitsubishi Zero was 6th), and the He1 means it is the first version of this particular design, built by Heinkel.

In testing the He 112B proved superior to the A5M2 in many ways, notably in speed where the 112 could easily outrun the A5M to the tune of 65 km/h. Yet the test pilots rejected the plane out of hand because the A5M was more maneuverable. Maneuverability was considered to be the single most important factor for any fighter among the IJN pilots, everything and anything was sacrificed to improve it. It could be said that the Japanese were still fighting WWI in the air, and the focus on maneuverability would later prove to be the downfall of their air forces.

In the end the He 112 was rejected and the option for the additional 100 was canceled. The thirty already purchased were delivered over a period in 1937 and '38, drawn from a number of production runs. Upon arriving in Japan they were used for training duties, but the V11 with its DB600Aa was used for testing. As it turns out the A7 designation would later be assigned to the Misubishi A7M, essentially an advanced Zero which never saw combat.

All plane types designed pre-wwII were tried and tested in Spain and/or Russia. Pilots such as Galland and Trautloft reviewed planes, wrote reports on improvements, and how it faired in combat. The 109 and 112 were some of the planes tested in spain. The 109 was chosen for many reasons over the He. And chances are these pilots favored it for a reason.

Lets dont compare the He-112 with the He-100, the first was reviewed on Spain and there the BF-109 was a superior aircraft.

However the He-100 was faster, and maybe with the replacement of wing 7.7mm mg for MG-FF the performances will close having the He-100 an advantage on medium to low altitudes and firepower (3x20mm cannons), no mention the range wich was higher than the BF-109.
The BF-109 still a good aircraft, not for nothing it was in service and continuous improvement even after the war (Avia 199)

In Spain, the He-112 was used primarily as a ground attack aircraft... because of the 20mm cannons... Bf109 only have MGs at that time.

It was fantastic for train busting. The big drag on the He-112 was many problems with it's engine. Romanian He-112s were lost most to the engine than the russians.

BTW... the US p38 downed by a He-112, was caught on absolute surprise executing an attack from the sun with altitude advantage. The P38 managed to crashland on friendly territory. Not to mention that the flight never expected any spanish plane intercepting them.
