Fw 189 in Hungarian Service

Hungarian Flag Kingdom of Hungary (1943)
Reconnaissance aircraft Over 28  

During the Second World War, Hungary aligned itself  with the Axis powers, and in 1941, they dispatched their armed forces to support the German invasion of the Soviet Union. Initially, the Hungarian Army, particularly its Air Force, was poorly equipped for this conflict and lacked many vital military resources, particularly modern weapons and aircraft. For example, its Air Force had to conduct tactical reconnaissance using obsolete biplane aircraft. In 1943, to support their ally, the Germans supplied a small group of the modern Fw 189 reconnaissance aircraft to the Hungarians. Although these aircraft were limited in number, they saw extensive action until the end of the war.

History

Despite many attempts to improve its Air Force during the 1930s, Hungary faced numerous obstacles that hindered its progress. The most significant challenge were the restrictions on developing certain military technologies, including aircraft, imposed by the Treaty of Trianon in June 1920. Although the geopolitical landscape in Europe had changed considerably by the 1930s, rendering the Western Allies incapable of enforcing this ban, it did little to assist Hungary. The country simply lacked the financial resources and could not find any potential sources from which they could purchase a large number of new aircraft from.

As a result, the Hungarian Air Force had to rely on the Weiss Manfred WM 21 Sólyom, a biplane developed domestically in the late 1930s, for reconnaissance operations. Fewer than 130 of these aircraft were built. To supplement the WM 21, Hungary acquired the Heinkel He 46 from Germany. However, by the time Hungary entered the war with the Soviet Union in 1941, both aircraft were clearly obsolete. Nevertheless, with no better alternatives available, they had to continue in their reconnaissance roles.

By 1943, it had become clear to Hungarian Air Force officials that the two aging aircraft in their fleet needed to be replaced. With limited options available, they turned to the Germans for assistance. At that time, Germany was deeply entangled in the conflict with the Soviet Union and was in desperate need of support from its allies. Realizing the necessity of keeping Hungary well-equipped in the fight against the Soviets, the Germans agreed to supply a small contingent of the well-known Focke-Wulf Fw 189 reconnaissance aircraft to reequip the Hungarian forces.

A Brief Fw 189  History

The history of the Fw 189 dates back to 1937, when the German Ministry of Aviation initiated the development of a new tactical reconnaissance aircraft. The role of the aircraft was to survey the front line, and carry out army liaison duties. One of the companies that responded to this competition was Focke-Wulf, which presented the Fw 189. This aircraft won the contract, leading to a production order that began in 1940. The Fw 189 was a twin-engine aircraft with a heavily glazed central fuselage which gave its crew excellent visibility. It was well-liked in service and generally performed well, with most of them being employed on the Eastern Front. By the time production ended in 1944, some 900 of these aircraft had been built.

Operational Service Life 

While the Fw 189 aircraft were allocated to the Hungarian Air Force, they operated under German command. This was not irregular; in fact, to better coordinate their efforts, large parts of the engaged Hungarian Air Force were placed under German operational control. In May 1943, Germany supplied the Hungarians with a group of 12 Fw 189A models, which were assigned to the 3rd Hungarian Flying Squadron under the command of Captain Lorand Telbisz. This squadron was subordinate to the German 4th Air Fleet.

The first aircraft operated from airfields near Harkow, where they undertook over 224 reconnaissance missions against Soviet forces. Some of these missions even targeted Soviet partisans in the Pripet Marshes. During one of these operations, the Hungarians lost their first Fw 189, when it was shot down in late May.

The aircraft also saw heavy action during the Battle of Kursk, performing reconnaissance missions and, in many instances, conducting light bombing attacks against enemy forces. However, with the failure of the German offensive, the Hungarian forces were forced to retreat as well.

In September 1943, a lone Hungarian Fw 189 achieved remarkable success against Soviet fighters. On the 21st, during a reconnaissance mission, the Hungarian Fw 189 was engaged by a group of three Yak-9 fighters. To evade the enemy, the Fw 189 pilot descended sharply, making abrupt turns. Despite intensive enemy fire, the rear gunner managed to shoot down one of the fighters. A second Soviet fighter was lost when its pilot misjudged his altitude and crashed into the ground. The last surviving fighter disengaged and retreated. While the Fw 189 lacked for a heavy defensive armament, its spindly form and exceptional maneuverability made it a difficult target for interceptors, when an experienced pilot was at the controls.

Later that same day, another Fw 189 was attacked by at least six La-5 fighters. After extensive maneuvering and exchanging of fire, the rear gunner of the Fw 189 claimed two of the attackers. In both cases, the Fw 189s successfully returned to their bases.

During this period, the Germans added a few more aircraft to the unit to replace losses and worn-out planes. By the end of October 1943, the 3rd Flying Squadron had completed its 1,000th flight mission. However, while it remained active until the end of the year, a lack of fuel and spare parts greatly reduced the number of operational flights. By March 1944, the unit had only one operational aircraft left. That same month, the unit was officially disbanded, and the surviving personnel were sent back to Hungary.

The story of the Fw 189 in Hungarian service did not end there. In April 1944, the 4th Reconnaissance Squadron was relocated to Hungary and stationed at Bydgoszcz. The squadron’s crew underwent training in night reconnaissance operations, which were completed by May. Following their training, the unit engaged in extensive action on the Eastern Front, ranging from Poland to Hungary. They remained active on the frontline until September, when it was disbanded. Following the unit’s dissolution, the surviving aircraft were returned to the Germans. While the exact number of Fw 189s operated by this unit is unclear, they are known to have lost between 10 and 11 aircraft of this type to all causes. This marked the end of the Fw 189’s service within the Hungarian Air Force.

It is not clear precisely how many aircraft of this type were operated by the Hungarians. Author G. Punka (Hungarian Air Force) places the number of  28 aircraft of this type, while in another book, Hungarian Eagles, written by  Sarhidai, G. Punka, and V. Kozlik, a figure of 21 is given. While most of these received Hungarian Air Force markings, many of them retained the original German markings, which makes identification somewhat confusing, likely contributing to this ambiguity.

After 1943, the Fw 189 would still see service within the Hungarian Air Force but primarily for night reconnaissance operations. Source: https://old-forum.warthunder.com/index.php?/topic/490017-visegrad-group-aviation-tech-tree/page/3/

Technical  Specification

The Fw 189 was designed as a twin-engine reconnaissance aircraft with a unique construction. Its central fuselage featured extensive glazing, with the cockpit at the front of the compartment, followed by a small crew area, and a gunner’s station at the rear. The fuselage was bulkier at the front and tapered toward the rear. Access to the crew area was provided through two hatches above the cockpit and a larger hatch at the rear. Although the extensive glazing left the crew more exposed to enemy fire, it was ideal for its reconnaissance role, offering excellent all-around visibility.

The wings are composed of two distinct sections. The central, square-shaped panel connects the nacelle and engines, while the second section extends outward from the booms. The wings feature a metal base covered with duralumin, though the ailerons and split flaps are clad in fabric.

The aircraft was powered by two 465 hp Argus As 410 A-1 12-cylinder air-cooled V-12 engines. These engines demonstrated remarkable effectiveness and reliability, even under the harsh winter conditions of the Eastern Front. With these engines, the Fw 189 achieved a maximum speed of 335 km/h, though exact figures may vary between sources. Each engine drove a two-blade, constant-speed propeller. Fuel was stored in two 110-liter tanks, which were housed in the tail booms. The Fw 189 had a maximum operational range of approximately 670 km.

The landing gear consisted of two landing gear assemblies that retracted into the engine nacelles. The rear smaller tail wheel was located inside the vertical stabilizer and was retracted in flight. While nominally a reconnaissance aircraft, the aircraft could be armed with machine guns for strafing targets, and had four underwing shackles for bombs, or flares.

Conclusion

The Fw 189 was a well-designed aircraft that excelled in its intended role. Given its effectiveness, it’s no surprise that the Hungarians made extensive use of the few aircraft they were supplied with. These planes were deployed exclusively against the Soviets, primarily in 1943 and late 1944.

WM–23 Ezüst Nyíl

Hungarian Flag Kingdom of Hungary (1939)
Fighter Aircraft – One prototype

In their search for a new fighter, the Magyar Királyi Honvéd Légierő MKHL (English: Royal Hungarian Home Defence Air Force), approached the Germans for help. Initially, a deal was made with the German Heinkel company for the delivery of new He 112 fighters and a production license. However, nothing came of this deal, which led to the Hungarians attempting to develop their own fighter, partially based on the He 112.

The He 112 In Hungary

In the late 1930s, the Hungarian Air Force was slowly in the process of rebuilding its combat strength by the acquisition of new aircraft. For a modern air force, they needed better fighter designs, which they were then seriously lacking. Luckily for them, they began to improve their relations with Germany, so it was possible to acquire new equipment from them. In June 1938, a  Hungarian delegation was sent to the Heinkel company, and the pilots that accompanied this delegation had a chance to fly the He 112 fighter. This aircraft was  Heinkel’s response to the Reichsluftfahrtministerium’s (English: German Ministry of Aviation) request for a new fighter. While generally a good design, it ultimately lost to Messerschmitt Bf 109. While the He 112 project was canceled by the RLM, to compensate for the huge investment in resources and time to it, Heinkel was permitted to export this aircraft to foreign buyers.  Several countries such as Austria, Japan, Romania, and Finland showed interest, but only a few actually managed to procure this aircraft, and even then, only in limited numbers.

The Hungarians were impressed with the He 112 and placed an order for 36 such aircraft. For a number of logistical and political reasons, the decision to sell these aircraft to Hungary was delayed.  A single He 112 was given to Hungary in February for evaluation but was lost on its first flight. Realizing that the Germans would not deliver the promised aircraft, the Hungarians instead decided to ask for a license. This was granted and Heinkel also delivered two more He 112 B-1s. When the license arrived in Hungary in May 1939, a production order for the 12 first aircraft was given to Weiss Manfréd aircraft manufacturer.

A New Fighter

Despite the best Hungarian attempts to put the He 112 in production, this was prevented by the war between Poland and Germany. At the start of the Second World War, RLM officially prohibited the export of any German aircraft engines and equipment. This meant that the vital Jumo 210 and DB 601 engines would not be available. Based on this fact, all work on the Hungarian He 112 had to be canceled.

As the Hungarians had the license for the He 112, some parts could still be domestically produced. In essence, this offered the Hungarians the chance to develop a new fighter, based on the He 112 blueprints. Not wanting to waste this opportunity, the Hungarian Ministry of War Affairs issued a directive to commence developing a new domestic fighter by reusing some components from the He 112. The whole project was undertaken by WM’s own chief designer Bela Samu, who began development in early 1939. To speed up development, the He 112 wing design was copied, but given the comparatively underdeveloped Hungarian aircraft industry, the wing was to be built of wooden materials instead of metal, as it was on the He 112. Other differences included using an oval-section fuselage, different armament, a new engine, and a cockpit redesign.

The first prototype was completed quickly by the end of 1939. In its prototype stage, the aircraft was painted in a light gray livery, earning it the nickname Ezüst Nyíl (English: Silver arrow)  from the personnel that worked on it. Once it was issued to the Air Force for testing, it received the standard Hungarian camouflage scheme, and the designation V/501 was also allocated to it. The maiden test flight was undertaken close to Budapest on the 23rd of February 1940. The flight proved successful and a maximum speed of 530 km/h (330 mph) at a height of 5 km (16.400 ft) was achieved. Some issues were detected, the most problematic proved to be the strong vibration caused by the exhaust system. Despite this, the project development pressed on.

Short Service Life

Despite the time and effort put into the project, it all went for nothing as the prototype was lost in an accident in February, or April, depending on the source, 1942. During a test flight at high speeds, one of the ailerons simply broke off. The pilot lost control of the aircraft and had to bail out. The uncontrolled plane hit the ground and was utterly destroyed, and with it, the whole project was canceled.

Beyond this major setback, another reason why this project was canceled was the start of the license production of the German Bf 109G fighter. It was much easier, and faster, to commence production of this aircraft, thanks to German technical support, than to completely develop new tooling and equipment for the WM 23.

Technical Characteristics

The WM 23 was a mixed-construction single-engine fighter heavily inspired by the German He 112. Given its somewhat obscure nature, not much is mentioned in the sources about its overall construction. Given the urgency of the project, instead of the monocoque fuselage, the Hungarian engineers decided to use a simpler oval-section fuselage which consisted of welded steel tubes and then covered with plywood. The wings, as mentioned, were taken from the He 112, but had one huge difference, being made of wood, including its control surfaces.

The landing gear was another part more or less taken directly from the He 112. They consisted of two larger landing wheels that retracted into the wings, and one semi-retractable tail wheel. But based on the photographic evidence, their overall design changed during the prototype’s development. On the prototype, possibly at an early stage, a V-shaped front landing gear strut was used. This was later replaced by a large single-leg landing gear. The cockpit was equipped with a sliding canopy that slid to the rear.

The WM 23 was powered by a 1,030 hp WM K-14B (sometimes marked as 14/B) engine. This engine was developed based on the license of the  French Gnome and Rhone 14K engine, a fourteen-cylinder radial engine equipped with a single-stage, single-speed supercharger. As mentioned, during the fifth test maximum achieved speed was 530 km/h (330 mph).

While the prototype was never fitted with an offensive armament, the Hungarians had plans for a potential armament In the wing, two 8 mm (0.33 in) machine guns were to be installed. In addition, two 12.7 mm (0.5 in) heavy machine guns were to be added atop the engine compartment. Lastly it was to have a  payload of two 20 kg bombs  (44 lbs).

Conclusion

The WM 23 was an interesting Hungarian attempt to domestically develop and build a fighter aircraft that was greatly influenced by the He 112. It showed to be a promising design, with the prospect of entering serial production. However, the loss of the single prototype put an end to this project. By 1942, the Hungarians simply did not have the time to start over again with the WM 23, so they abandoned it in favor of the license production of the German Bf 109G.
