В.Кондратьев Самолеты первой мировой войны


В сентябре 1915 года на "Фоккер" E.III решили установить двухрядный 14-цилиндровый ротативный мотор "Оберурсель" U.III мощностью 160л.с. Новая модификация получила обозначение "Фоккер" E.IV. Значительное повышение энерговооруженности машины позволило усилить вооружение - на самолет установили три синхронных пулемета LMG.08. Правда такую огневую мощь посчитали избыточной, а вибрацию при стрельбе из трех "стволов" - чрезмерной, поэтому в серию самолет пошел с двумя синхропулеметами. Еще одним отличием от E.III стало то, что казенные части пулеметов закрыли металлическим обтекателем, переходящим за вырез кабины пилота. Впрочем, нельзя сказать, что это сильно отразилось на аэродинамике.
   E.IV строился малыми сериями с октября по декабрь 1915 года параллельно с E.III. Ежемесячно выпускалось в среднем по шесть машин. Затем, в феврале 1916-го последовал более крупный заказ на 30 самолетов, а после его выполнения постройка прекратилась. Таким образом, всего было сделано 49 экземпляров, включая прототип.
   E.IV продемонстрировал более высокую скорость, чем его предшественник, однако значительный гироскопический момент тяжелого ротативного мотора обусловил увеличение инертности и ухудшение горизонтальной маневренности . По этому показателю Е. IV значительно проигрывал новым истребителям-бипланам союзников, появившимся на фронте одновременно с ним. Управляемость, по отзывам пилотов, также ухудшилась.
   Весной 1916 г. немецкие авиаконструкторы решили отказаться от дальнейшего использования монопланной схемы в истребительной авиации. Однако к началу мая того года количество истребителей-монопланов в германских авиачастях достигло максимального значения (35 "фоккеров" E.I и E.II, 110 E.III, 28 E.IV и 56 "пфальцев"). В дальнейшем это число постепенно снижалось и к февралю 1917-го - сошло на нет.

A.Weyl Fokker: The Creative Years (Putnam)


The twin-gun installation was developed after Boelcke told Fokker that it would be welcomed, not only because it would double the fire-power but also because it would reduce the effects of the frequent gun troubles. The grip on the control column was modified: it had two key levers, side by side, to fire the guns; and the handles of the grip proper were smaller and parallel to each other. Better climbing performance and greater speed at altitude were needed. Oberursel were now building a two-row engine of some 160 h.p. that might effect the necessary improvements.
   Immelmann had even more ambitious ideas. He proposed a battery of three guns for maximum fire power during the few seconds in which the enemy aeroplane could be held in the sights. His experience convinced him that the first attack was all important, and that surprise attacks from below and behind were likely to be most effective: an observer could neither spot the attacker nor use a defending gun if he had one. For such attacks Immelmann thought the guns should be mounted at an upward angle. He also required the cocking levers to be conveniently placed in the cockpit, better protection against draught, a climb to 3,000 m. in no more than 15 minutes, and a speed of 160 km./hr. (100 m.p.h.). Immelmann stressed the importance of good performance at altitude.
   But three guns with their ammunition were a heavy load, and a new variant of the Stangensteuerung would have to be devised for such a battery. Fokker was not perturbed by such technical problems, so Immelmann’s scheme was tried. Immelmann requested that the new fighter be powered by a 160-h.p. two-row Le Rhone engine taken from a special Morane that had landed intact in the German lines. Although a modification of the aircraft built to incorporate Boelcke’s suggestions, Immelmann’s machine might itself have served as a basis for further development. Boelcke was to have the first production machine of the new type, with the two-row Oberursel and twin guns; Immelmann’s was to go direct to the front for operational evaluation.
   Apart from the increased armament, the new type had a number of modifications to the airframe and was designated M.15. The two-row Oberursel U.III needed a fore-and-aft mounting, to which end Platz devised a spider type of mounting similar in principle to that of the Avro 504. This engine mounting provided attachment points for strong external drag bracing, which Kreutzer still considered essential. The cowling had to be completely redesigned, not only because of the new mounting but also to provide better cooling, especially of the rear row of cylinders. The upper bracing pylon was strengthened, and a turtle-back fairing was fitted behind the cockpit to reduce draught. The passenger space had been abandoned in the M.14.
   The M.15 prototype (probably E.125/15, factory No. 374) was ready early in November 1915. It had the first 160-h.p. Oberursel, and was assessed by Parschau at Schwerin. His report, dated November 13, 1915, is as follows:
   “The following climbing performance was achieved with fuel for 1 1/2 hours, two machine guns and 950 rounds of ammunition on board -
   1- 0 km. in 2-75 minutes
   2- 0 km. in 7-0 minutes
   3- 0 km. in 15 minutes
   4- 0 km. in 28-5 minutes
   During offensive patrols, practical climbs are -
   3- 0 km. in 20 minutes
   4- 0 km. in 40 minutes
   In level flight at 1-0 km. altitude the indicated maximum speed is 195 km/hr (121 m.p.h.). Maximum speed determined by flying over known distances seems to be about 165-170 km/hr (103-106 m.p.h.).
   “Considerable force has to be used in warping the wings in steep turns; this can be eased by blipping the engine. The aircraft’s high speed may make it approach a target too quickly when attacking from the rear, and it may be advisable to cut the engine or to approach from below and astern.
   “Ammunition belts of hemp are better than metal belts. The belt feed guide no longer has the right-angle bend, and the ammunition containers have been reduced in width so that cartridges no longer come loose in the belt; the containers are less susceptible to vibration because they have a forward support. These modifications should make ammunition-feed trouble less likely.
   “During longer flights oil fumes can be troublesome. The latest modification therefore provides for the sealing of the fuselage from the engine. The fuel consumption is reasonable. At high altitude the engine loses much power owing to the low temperature. A suggestion made by Morell for a shielding device should be tried.”
   Leutnant Frhr. von Thuena, an experienced pre-war pilot then in charge of aircraft development at the IdFlieg, added a postscript recommending a variable cowling for the engine: this should operate in accordance with the dynamic air pressure, to reduce the loss of power at altitude. He suggested also that an atomizing cone should be fitted in the carburettor jet to achieve a more uniform mixture.
   Lt. Parschau’s rather optimistic report convinced the Feldflugchef that the Fok. E.IV was indeed a very advanced aeroplane. It did not greatly matter that Parschau had overestimated the speed, but it soon became obvious that he had failed to assess the aircraft’s lack of manoeuvrability.
   Immelmann’s special E.IV (E.189/16, Factory No. 385) with its triple gun installation was ready in December 1915. The special Le Rhone and its airscrew were not immediately available, so a 100-h.p. Oberursel was temporarily installed to enable Fokker to test the machine. After the Le Rhone had been fitted, Fokker saw a welcome opportunity of demonstrating the new aircraft when a rumour of an air attack on the Krupp works had produced a concentration of noted fighter pilots at Essen. But the synchronizer malfunctioned, sixteen bullets struck the propeller and nearly shot the blades away. A thoroughly frightened Fokker had to make a hasty landing.
   The aircraft was sent back to Schwerin for repair, and Immelmann finally took it over on January 16, 1916. Various troubles prevented him from using it in action before February 6, 1916. In March he shot both propeller blades away but managed to land without further damage. He seems to have destroyed two Allied aircraft while flying this special Fok. E.IV, but he came to dislike it. Lack of spares for the big Le Rhone led to its replacement by a 160-h.p. Oberursel. Boelcke, who was interested in the multi-gun installation, tried the aircraft but reported adversely on the tilted guns.
   Boelcke had received his standard E.IV on December 13, 1915. He too had the experience of shooting off his own airscrew: the resulting unbalance caused failure of the engine mounting, but he managed to land safely. On May 31, 1916, Immelmann had another incident of the same nature when he was flying a standard twin-gun Fok. E.IV. Fokker blamed the failure of a rocker arm in the engine for cutting through all but two of the engine-mounting struts. This was by no means impossible, but it is equally probable that the synchronizer had failed again - as Immelmann himself apparently believed.
   Production of the 160-h.p. Oberursel was slow - all its cylinders were machined out of solid steel blocks to the closest tolerances - and regulated production of the Fok. E.IV. Moreover, its lubricating castor oil was scarce. It was therefore decided that the Fok. E.IVs were to be reserved for top-ranking fighter pilots. Less distinguished pilots were to stick to the Fok. E.III, which was in quantity production.
   On the whole, the E.IV was a disappointment. Its performance fell short of expectations, partly because the authorities had specified much too great a load for the little monoplane, partly because the engine’s low compression ratio led to loss of power at altitude. This last defect was aggravated by the poor feeding allowed by the automatic inlet valves.
   Boelcke, then in command of the Fokker detachment at Sivry, reported on March 24, 1916, that the E.IV’s speed, although appreciably less than the promised 100 m.p.h., was adequate for operational purposes. In climbing, however, much speed was lost, and several Nieuport biplanes had escaped Boelcke because of this deficiency in the Fokker. Above an altitude of 3-0 km. the rate of climb was inadequate.
   The 160-h.p. Oberursel was tolerably good when new, but lost 40 to 50 r.p.m. at altitude; after some use it deteriorated quickly and would lose 100 or more r.p.m. at operational height.
   But the chief drawback was that the Fok. E.IV was less manoeuvrable than its predecessors, owing to the big rotating mass of the engine. Quick turns could only be made by blipping the engine: this entailed loss of height, a hazardous matter when fighting an enemy flying at the same altitude or higher.
   It was in his report of March 24, 1916, that Boelcke condemned the upward-firing guns originally advocated by Immelmann. On the strength of Boelcke’s report the Feldflugchef decided that fixed guns should be aligned with the direction of flight as before. On March 29 Boelcke was sent to Schwerin to discuss with Fokker the design of a better fighter, preferably a biplane.
By that time the Fokker monoplane’s supremacy was on the wane, and by the summer of 1916 it was painfully obvious that the Fokker had been kept operational too long on the Western Front and its replacement by aircraft with more reliable engines and better performance was overdue. In the east, Fokker monoplanes went unchallenged until late in 1916; and coast-defence units of the Navy, which had only Russian naval aircraft to deal with, were able to use them even longer. Austria seems to have made some little operational use of the small number of Fokker monoplanes supplied to her Luftfahrttruppen, for they were seen in action by the Italians. They seemed to score no confirmed victories, however, and none of them fell into Italian hands.
   In the west, defeats and losses of Fokker monoplanes became progressively more numerous from April 1916 onwards. Most of the Fokker pilots paid dearly for their early successes: of the first fifteen none lived to see 1917. On April 30, 1916, Graf von Hoick was shot down in flames in his Fokker E.III over Verdun during a combat with three Caudrons. In June, Hauptmann von Gersdorff, leader of No. 1 Combat Squadron, was shot down in flames. Boelcke, too, had a close shave when a French Nieuport shot him down with its unsynchronized gun. On June 18 Immelmann crashed to his death, and the fate of the Fokker E was sealed. All Fokker fighter monoplanes were either relegated to training duties or sent to the Eastern Front.
   The cause of Immelmann’s death has been, and will probably continue to be, the subject of controversy. All accounts agree that his twin-gun Fokker E.III broke up in the air, but it is uncertain whether its disintegration followed structural failure after malfunctioning of the interrupter gear caused in airscrew breakage, or by damage resulting from the attack of Lt. G. R. McCubbin and Cpl. Waller in an F.E.2b of No. 25 Squadron R.F.C.
   On his last flight Immelmann was flying a standard Fok. E.III with twin guns and a single-row 100-h.p. Oberursel. Although the significant portion of the aircraft was very badly damaged, the Germans claimed that it contained clear indications that Immelmann’s synchronizing gear had failed, one airscrew blade had been shot away, the resulting unbalance had torn the engine from its bearers and caused severe damage, and complete structural failure had been accelerated by the pilot’s attempts to regain control of his aircraft.
   Not unnaturally, it was thought that parts of the forward fuselage might have failed because of faulty welding. Sand-loading tests carried out by the Prufanstalt und Werft of the IdFlieg at Adlershof vindicated the Fokker construction methods: the fuselages that were tested to destruction were not only faultless but were substantially stronger and more resilient than they were required to be.
   A word must be said about the fighter component of the Marine-Flieger-Abteilung, the coastal defence unit of the German Navy that flew landplanes. The unit had maintained an interest in Fokker aircraft after Ernst Ditzuleit had proved to the Navy’s satisfaction that these aeroplanes could be used for longer flights. In the summer of 1915 he flew the Fokker M.5L “S.27 Kiel” to Kiel-Kopperpahl, the flight lasting 3 1/2 hours. Although the cylinders of his 80-h.p. Oberursel had turned blue by the time he landed, the flight was accepted as evidence of the Fokker’s capabilities. The Navy therefore sent a detachment of seven pilots, including Ditzuleit, to the Kampfeinsitzer-Schule at Mannheim, and a number of Fokker E.IIIs and E.IVs were ordered. These aircraft were used operationally, mainly in the east. Of the seven naval fighter pilots, only two survived the war.

Eindecker Development Notes

<...>
Fok. E.IV (M.15)

  As per the E.III, the Fokker M.15 design was an adaptation of the same basic airframe to accommodate a more powerful engine arid increased firepower. The fuselage was again lengthened and the wings/undercarriage/cockpit moved closer to the nose. The new engine was the 160 hp Oberursel U.III, which required an additional frame to support the extra weight. The E.IV was originally designed to carry a battery of three LMG08 guns. The aluminum panels were revised and a turtle deck was introduced to enclose the pilot's space in the cockpit.
  The first three E.IVs were configured to carry the three guns, but difficulties in timing the interrupter system led to all three aircraft leaving the factory with the port weapon removed. Subsequent E.IV production had two LMG08s mounted symmetrically.
  That is not to say that all Fokker E.IVs at the front had only two guns. Leutnant Kurt Wintgens, one of the most accomplished Eindecker pilots and the recipient of one of the first E.IVs that had had the starboard gun removed, reinstalled the third MG. He used this modified Eindecker extensively and successfully during the summer/fall of 1916.
  A final note about the Fokker E.IV: history has not been kind to the ultimate Eindecker. Its shortcomings have been well documented and the Fokker E.III is generally considered the best of Fokker's monoplane designs, as it was produced in the largest numbers. However, almost all of the most prolific Eindecker pilots flew the E.IV. The number of combat victories achieved in the type by this relatively small group of kanonen exceeded that of any of the other Es, making the E.IV the most successful Fokker E-type, if not the superior aircraft.


Fokker E.IV (Fokker M.15)

  The Fokker E.IV can be distinguished from the earlier Fokker Eindeckers by its two-row, 14-cylinder, 160 hp Oberursel U.III rotary engine and the longer cowling needed to cover it. The wing remained the same as earlier Eindeckers but the fuselage was lengthened to balance the heavier engine. The additional power enabled the E.IV to carry a second machine gun while simultaneously improving the E.IV's speed, climb, and ceiling compared to earlier Eindeckers. The Fokker company designation for the new type was M.15.
  However, the more powerful engine was not as reliable as the single-row rotaries used in the earlier Eindeckers, and the additional weight of the larger engine and second gun noticeably reduced maneuverability. So the E.IV was not an unqualified success on operations, especially because it appeared at the front about the same time that improved Allied biplane fighters, the Nieuport 11 and DH.2, also reached the front. While the E.IV could match these new types in speed and had better armament, both biplanes had better climb and maneuverability. The race for technical superiority in fighter aircraft now began in earnest.
  Two E.IV prototypes and the first production machine were tested with three synchronized machine guns, leading to the myth that operational aircraft also carried three guns. The third gun added too much weight and also caused synchronization problems, so it was not adopted for operational aircraft. In fact, the port gun was removed from the three machines that initially carried it before these aircraft were sent to the front. Photos of E.IV 123/15, an early E.IV flown by Oswald Boelcke, show that it had two guns offset to starboard, the port gun having been removed at the factory. Later E.IV fighters had their two guns mounted symmetrically to the aircraft's centerline.

Fokker E Series
  
   Mention must be made of the E.IV (of which some thirty examples were produced), a last-ditch effort on Fokker's behalf to prolong active life when the type was obsolescent, since the legend of the Fokker's invincibility had been shattered by the spring of 1916. The E.IV was virtually an enlarged E.III fitted with two machine-guns and with a 160 h.p. Oberursel U III engine. This was a fourteen-cylinder, two-row, rotary and had not the reliability, or flexibility, of the less powerful rotaries. Due to its weight it made the E.IV far less nimble than the E.II and E.III. Immelmann had one which had been especially equipped with three machine-guns, but performance was so poor, due to the increased weight, he reverted to the E.III, on which type he was eventually killed on 18th June 1916 during combat with an F.E. 2b of 25 Sqdn. R.F.C., flown by Lieut. G. R. McCubbin and his observer Cpl. J. H. Waller. However, Oblt. Student of Fokkerstaffel der III Armee (later on Jasta 9) preferred the E.IV to the E.III and operated with success in the Verdun sector.
   The E.I/E.IV monoplanes were of composite steel and wood construction, and bore an extraordinary degree of resemblance to the French Morane Saulnier monoplanes in both structure and appearance. The fuselage was completely fabricated from welded steel tube, with small brackets welded into the corners of the bays to form anchorages for the bracing cables, which were looped round them and joined with a single turnbuckle. Terminating in a horizontal knife-edge, the fuselage was completely slab sided except for two metal cowling panels at the sides of the extreme nose, which continued the circular section of the cowl for a short distance, and for a rounded top decking extending as far aft as the cockpit, also of sheet metal. The horseshoe-shaped cowling was cut away in the lower segment as a precaution against the accumulation of petrol, which might have drained through the valves and caught fire. The comma rudder and trapezoidal-shaped elevators were of the "all-moving" variety, with no fixed fin surfaces, and demanded continual vigilance from the pilot.
   Of parallel chord, the wings were angularly raked at the tips and were a quite flexible structure built on two I-section main spars. The ribs were of poplar, thin in section to afford the degree of flexibility necessary for the warp-type lateral control that was used in the design. The bracing of the wings was by four cables to each panel, anchored to an upper and lower pylon and to the forward main spar. A similar number of cables for lateral control were anchored to the rear spar but ran over pulleys at the apices of the pylons and thence into the cockpit, where they were connected to the control stick.
   The undercarriage was a somewhat complex steel-tube structure which also incorporated the lower cable anchorage pylons; the elastic-cord shock absorbers were attached to the tops of the main vertical members inside the fuselage. An inverted pylon of light-gauge steel tube supported the tailskid and also served as a pivot for the lower extremity of the rudder.

FOKKER E IV (M 15) Germany

   Several of the most successful Fokker Eindecker pilots, including Max Immelmann and Oswald Boelcke, asked Anthony Fokker to develop a more powerful and more heavily armed version of his fighting scout. As a consequence, the M 15 was evolved, the first example of which was delivered in September 1915 as the E IV. Embodying modest increases in overall dimensions, the E IV was powered by the 160 hp Oberursel U III two-row 14-cylinder rotary engine, and, in standard form, was fitted with paired synchronised LMG 08/15 machine guns. At least one example of the E IV was completed (for Immelmann) with the then unprecedented fixed-gun armament of three LMG 08/15s. The success of the E IV at the Front was limited and production was restricted to 49 examples, of which the last was delivered in July 1916.

Fokker E.IV flown by ace Kurt Wintgens while he was assigned to Flieger-Abteilung 6. The larger cowling for the two-row rotary distinguishes the E.IV from earlier E-types. Wintgens scored 19 victories and was awarded the Pour le Merite. He was killed in action 25 September 1916.

Fokker's M.15 design was a continuation of the M.14, modified to mount the more powerful 160 hp Oberursel U.III and carry a battery of three machine guns. This is the prototype, werknummer 298. (Peter M. Grosz collection/STDB)

This Fokker M.15 (E.IV) was set up at the factory to shoot a number of documentation photos of the three machine gun installation. Although Boelcke tested such a gun installation, he reportedly disliked it.
J.Herris, J.Scott - Fokker Aircraft of WWI. Vol.2: Eindeckers /Centennial Perspective/ (52)
Although it looks like there are only two LMG08s mounted in this photo of the M.15 prototype, the port gun is actually directly in line visually with the center MG. This airframe had the same "deflector plate" beneath the fuselage as seen on the previous E-types. (William Toohey)
J.Herris, J.Scott - Fokker Aircraft of WWI. Vol.2: Eindeckers /Centennial Perspective/ (52)
The fuselage of the E.IV was lengthened and the wings were moved closer to the nose in order to balance the heavier U.III engine, extra guns and ammunition.The tail unit, undercarriage and M.14 wings were retained from the previous Eindecker designs. The wings have a decidedly darker finish than the fuselage on M.15 w/n 298. (Peter M. Grosz collection/ STDB)

A factory documentation view near to pilot's-eye view of an experimental triple 7.92mm Spandau gun installation synchronized to fire through the propeller arc of this Fokker E IV. This fit was the culmination of Fokker's efforts to arm his early monoplanes, or eindeckers and although Max Immelmann tested this three-weapon fit, he preferred the Eindecker's standard single gun installation. The bar visible inside the cockpit was the firing control for the three guns.

Tony Fokker in the cockpit of a three gun armed Fokker M.15 (E.IV). Fokker flew a number of test flights with this aircraft and on one flight the synchronizer failed to function properly and Fokker put some sixteen rounds into his propeller, nearly shooting it away. Somewhat shaken, Fokker was able to make a safe landing.

That the Oberusel U.III engine was in fact two 7-cylinder U.0 engines bolted together is obvious here. With the first E.IVs, the LMG08 guns were mounted at a shallow angle, although not as extreme as the 15° often quoted. Each of the three guns had their own pushrod interrupter system. Unique to the first two E.IVs, the bottom longeron extended about a foot forward of the undercarriage legs. (Peter M. Grosz collection/STDB)

This is the gun installation on E.IV 122/15. Only the first three M.15 airframes had the structure to mount three LMG08s and only 122/15 had the fuel gauge set between the starboard and center guns. A compressed air tank replaced the port gun and may have been an experimental apparatus to pressurize the aft auxiliary fuel tank. With the exception of the previous photo, 122/15 was usually seen without the wind-driven generator seen on other E.IVs for this purpose. (Colin A Owers)

After some modifications, E.IV 122/15 shipped again on 20 October and was evaluated at the front by Lt. Otto Parschau. The port MG was removed and a small spinner was added to the propeller boss. Also, an additional window was installed in the cockpit's fabric wall and the windscreen was replaced. (Peter M. Grosz collection/STDB)

The third E.IV in sequence was Fok. E.IV 124/15 (w/n 374). It was the first to have the lower longeron angle upwards forward of the landing gear legs. It was also the first to have the aluminum side panels made with a curved trailing edge, although 124/15 had a unique curve-back at the bottom. (Peter M. Grosz collection/STDB)

Kurt Wintgens was the recipient of E.IV 124/15 in late January 1916, possibly while he was with FFA 12 in Burlingshofen, and he would use it extensively up to his death in September 1916. Like the first two E.IVs, this M.15 was intended to have three LMG08s, but arrived at the front with only two, the space for the port gun having been covered over. (Peter M. Grosz collection/STDB)

Much has been made about whether a 3-gun E.IV ever arrived at the front. Fokker lore has it that Immelmann received one. However, the photo presented here shows that there was indeed such a specimen in France - only it was in the hands of Kurt Wintgens. Fokker E.IV 124/15 is seen here, clearly with three LMG08s mounted. Wintgens had added in the third gun on his E.IV and overcome the issues with the three interrupter systems. (Lance Bronnenkant)

Wintgens is seen mounting Fok. E.IV 124/15. The presence of a Halberstadt fighter in the background suggests that this photo may have been taken at Jasta 1. He was brought down on 25 September 1916, likely in this E.IV. (Peter M. Grosz collection/STDB)

Baldamus achieved his first victory in this aircraft on 15 March 1916. In a letter home, he stated that only four pilots had received their E.IVs before him. Presumably, he meant Otto Parschau (E.IV 122/15), Oswald Boelcke (E.IV 123/15), Kurt Wintgens (E.IV 124/15), and Max Immelmann (E.IV 127/15). As E.IV 125/15 was tested to destruction, that leaves the likely candidate for this aircraft as Fok. E.IV 126/15. Unusually, a Wolff propeller is seen mounted on the Oberursel U.III in this photo. (Hannes Tager)
J.Herris, J.Scott - Fokker Aircraft of WWI. Vol.2: Eindeckers /Centennial Perspective/ (52)
Max Immelmann received Fok. E.IV 127/16 (w/n 377) on 16 January 1916. It had two LMG08s mounted symmetrically, as did Baldamus's machine and all subsequent E.IV production. (Peter M. Grosz collection/STDB)
The E.IV had a two-row, 160 hp Oberursel U.III rotary engine, and its larger cowling with additional cooling holes is clearly seen here. The additional power made the E.IV noticeably faster than the earlier Fokker fighters and enabled it to carry two machine guns. This makes the E.IV easy to distinguish from the earlier types, all of which look much alike and are often difficult to distinguish in photos. Immelmann was a famous early ace, and the Immelmann maneuver is named after him.

Leutnant Renatus Theiller of FFA 25 claimed his first victory on 25 March 1916, possibly in this early E.IV. After the first four of these new Eindeckers went to Fokker's favorite pilots, the others were doled out to the different Army groups, assigned to senior pilots with strong flying skills rather than combat victories. As an experienced pre-war flyer, Theiller may have received the initial E.IV for II Armee. The small circular hole in the side aluminum panel is unusual. (Coll. Jorg Muckler)

Oblt. Kurt Student stands with his late production E.IV at AOK 3 during June of 1916. As both 162/16 and 163/16 were assigned to this unit and looked largely identical, Student's E.IV could have been either. (Peter M. Grosz collection/STDB)

The end of the line. Nominally, Fokker E.IV 189/16 (w/n 578) was the final E.IV of the last production batch of M.15 airframes. Having been accepted on 26 July 1916 and delivered on 3 August, it was not actually the last E.IV completed. E.IV 188/16 was shipped on 7 August 1916 and E.IV w/n 679 left Schwerin on 10 August. 189/16 had no wooden fairings on the landing gear legs or national insignia on the fuselage at this time.

The early-production E.IVs in these two photos share numerous similarities which suggest that either or both may have been Baldamus's machine. Only 18 E.IVs were built that would have worn the 1915-style crosses, narrowing the possibilities. The fuselage stripe is green and white, Saxon colors for Baldamus.

A view inside the cockpit of a late-production Fokker E.IV. The aft crossbar supporting the LMG08s on these machines was level with the upper longeron. The brackets for holding the butt-end of the guns appear to be adjustable, perhaps allowing the pilot to change the angle of the guns. An altimeter is attached to the port side of the cockpit.

That contemporary captions can't always be trusted is proven by these photos. The removed cowling of this Fokker D.II allows a closer look at its 100 hp Oberursel U.I engine, 'Fokker D.D.' translates as "Fokker Biplane". Oddly, it was the Fokker monoplane (E.IV) seen in the background of the photos that was powered by the 160 hp Oberursel U.III instead. The unit and location are unidentified. This D.II was painted in a three-color camouflage scheme.

Naval Fokker D.I LF219 shows off its factory-applied camouflage pattern. This was only applied to the upper surfaces on a number of D.Is, and consisted of one color that is rendered as very light, while the other one appears fairly darken orthochromatic film. Note that the upper wing cross is applied onto a white square background, while the fuselage and rudder crosses are applied directly onto the plain doped fabric. Compare the fuselage crosses applied onto the plain linen fuselage and rudder of the D.I to the white cross background in used on the Fokker E.IV in the background.

Rare Line-up of eleven Fokker D.II, two Fokker E.III and one E.IV of KEK Habsheim at their airfield, circa September 1916. One of the hangars still carries the "Aviatik" name, the company operated a flying school at Habsheim before it was moved to Leipzig earlier in the year due to its proximity to the front. KEK Habsheim formed the nucleus of Jasta 15 when the Staffel was formed in October.

This photo of Kest 4b at Freiburg shows a first-generation Fokker E.IV fighter at left. Second-generation Fokker D.IIs are at the far end of the second row and the two closest fighters in the third row. Two second-generation Fokker D.III fighters are nearest the camera in the middle row. By far the best aircraft in the photo is the Halberstadt fighter furthest from the camera in the third row. The early Fokker biplane fighters were inferior to the Halberstadt and Albatros biplane fighters and were obsolescent on the Western Front. 1917 was a tough year for Fokker, who in January 1917 was directed to build 200 AEG C.IV two-seat trainers instead of his own designs.

When Kampfeinsitzerstaffel (Kest) 4b was formed by dividing Kest 4 into "a" and "b" designated half-units, they moved from Boblingen to Freiburg im Breisgau on 15 April 1917. This group photograph is thought to have been taken to commemorate their arrival at Freiburg, on or soon after this date. Their initial complement of fighters consisted of a somewhat motley collection of types: a Fokker E.IV named Hannah can be seen at far left, the only remaining Eindecker in the unit. The other aircraft seen in the picture are four Fokker D.III, three D.II, and a single Halberstadt, completing the rear trio of aircraft. Note the "Iron Cross" marked wheel hubs, which were possibly the new unit marking for Kest 4b.

In this photo of the grounds at the Schwerin-Gorries airfield, twenty-three E.IIIs from the 330-389/16 production batch can be seen (along with three E.IVs) waiting for engines and wings. Fok. E.III 368/16 heads the line at left, while 366/16 is third in line on the right side. It is interesting that none of these seemingly complete airframes have had the national insignia applied to their fuselages. The difference in size between the "flying" wheels on 368/16 and the "road" wheels on most of the others is very apparent. Fok A.I 5/16 is in the foreground. (Peter M. Grosz collection/STDB)

A rare glimpse into the fuselage assembly hall at Schwerin. Nearest to the camera is an upside-down Fokker E-type fuselage, with another laying on the starboard side next to it. Behind that is a Fokker M.18 fuselage, note that the cabane struts are an integral part of the welded fuselage structure. Numerous steel-tubes cut to the proper length can be seen in the picture.
In the foreground are three (including one hanging from the ceiling) M.14 frames that lack the steel tube framing for mounting a machine gun. Presumably these are from the last batch of Fok.

Fokker E.IV 162/16 (w/n 551) was documented at Schwerin. The firewall on the E.IV was not square, but rather the width at the bottom was wider than that at the top. The aluminum side panel had to bend to accommodate this. The "deflector" panel in front of the downward-view port in the bottom of the fuselage was a more stable, 3-faceted configuration on the E.IVs. (Peter M. Grosz collection/STDB)

Taxpayers' money wasted. The central staging area of the Schwerin-Gorries airfield became something of a morgue for disused Fokker airframes. The fuselages of around 40 Fokker Eindeckers E.III and E.IV and early D-Types are piled up to await disposition in the winter of 1916/17. All engines have been removed. Whenever possible, these were returned to their respective manufacturers or overhaul facilites in order to enjoy a second life in another airframe. Several D.I and D.II aircraft, identified by the upper wing center sections welded to the fuselages, can be seen. Dead center is E.III 222/16.

During a morning combat on 31 May 1916, Immelmann's synchronization failed and he shot off one of the propeller blades of 127/15. The resulting vibrations caused the Oberursel U.III engine to tear loose from its mount and he was lucky to land unhurt. Apparently the second blade broke off when he landed. A circular marking can be seen on the cowling/panel above the mechanics head, similar to the bullet patches seen on Immelmann's E.II. (Coll. Jorg Muckler)

Another shot of E.IV 162/16 being salvaged. A tripod sight has been fashioned in front of the guns and small rear sight is attached in front of the windscreen. An altimeter had been mounted to the port side of it. The manner in which the upper decking has been formed to go around the rigging pylon is noteworthy. The wings are stenciled "M.14 644". There is a mirror with bracket lying by the compass on the wing. (Peter M. Grosz collection/STDB)

Unlike previous E-types, photos of Fokker E.IVs returned to Schwerin for repair are rare. This late-production E.IV had an extra grommet in the fuselage fabric near the nose, possibly to accommodate an air intake tube for the rotary engine. (Peter M. Grosz collection/STDB)

A contemporary postcard illustrates a Fokker E.IV as it climbs to catch its Gallic quarry. Much discussion has been had over the color of the Eindeckers. While it seems certain that not all Fokker Es left the factory strictly in unbleached linen, the most common descriptions are of a straw, beige, or yellow finish, as seen here. Presumably the artist had either seen or heard a first-hand account of the color of the coarse fabric in use by Fokker on these aircraft. (Peter M. Grosz collection/STDB)
