The Messerschmitt (Me) Bf 109 is one of the most notable fighters of the Axis countries and a clear symbol of its air power during World War II. Its performance gave Germany the upper hand in the early stages of the war while also taking part in every front until the very end of the conflict in Europe. The Bf 109 was the main fighter of the Luftwaffe, later complemented by the Focke Wulf Fw 190. The Spanish Civil War was the Bf 109 saw its first combat action. It flew also with other nations such as Finland, Bulgaria, Italy, Spain, Switzerland, and Hungary. After the war, it was in service with the Israelis, serving also in the Yugoslavian, Romanian and Czechoslovakian Air Forces. The versatility of the fighter was one of the main factors that allowed it to serve until 1965, with numerous variants.

History

The Messerschmitt Bf 109 is single seat, single engine fighter tasked also with the roles of air superiority, interception, escort and attacking capable of all-weather operations in day or night. It was a light all-metal monocoque design with the rudder being covered with cloth. The wing was a low cantilever design fitted with flaps, while the canopy was enclosed, featuring retractable landing gear and a tailwheel, armed with machine guns and cannons. As a result, the Bf 109 was an advanced design at the time it was introduced. Its development began back in 1934, following a 1933 Reichsluftfarhtministerium study which considered that a single-seat fighter was needed to replace the Arado Ar 64 and Heinkel He 51 biplanes that were the German first-line fighters. Furthermore, it was required for the fighter to develop speeds of up to 400 km/h (250 mph) at 6000m (19,690 ft) for 20 minutes, having an range of 90 minutes. The power plant was intended to be the Junkers Jumo 210 engine of 700 hp, while the armament was intended to be comprised of a mixture of a 20 mm gun and two 7.92 mm guns, or be armed by either the cannon or the two machine guns only. In addition, as Willy Messerschmitt was not authorized by the Reichsluftfarhtministerium to build small passenger planes for Romania, the request of building a fighter came also as a sort of compensation.

Development

Bayerische FlugWerke began its work as it was awarded with the development contract in 1934, with the prototype flying for the first time in 1935, receiving the designation of Bf 109 by the aviation ministry and powered with a Rolls-Royce Kestrel IV engine, as new German-made engines were not yet available. Willy Messerschmitt was the designer behind the Messerschmitt Bf 109, hence the name of the aircraft, and the ‘Bf’ denomination. The development of the new fighter began, initially powered with the Rolls Royce Kestrel engine. The following two prototypes were powered with the Jumo 210A 600hp engines, and the last one was fitted with guns. Reportedly, 10 more prototypes followed in order to test the model. The result was a cantilever low-wing single engine fighter capable of speeds of up to 470 Km/h (Bf 109B) with its Junkers Jumo 210Ga engine. Further models received inverted Daimler Benz V-12 engines or racing engines. These engines yielded speeds of 380 mph (611 kmh) and 464 mph (755 kmh) respectively. Remaining the last a speed record for piston-engine aircraft until 1969. The fighter was very advanced, matching to any fighter in service at the time in combat. The earlier versions were armed with an array of two 7.92 mm machine guns in the forward cowl above the engine in the Bf 109B, while later C models were armed with two additional 7.92 mm machine guns in the wings and a 20 mm gun in the nose.

Presented to the public during the 1936 Berlin Olympics for propaganda purposes, it saw action for the first time during the Spanish Civil War with the German Condor Legion, where it quickly gained air superiority over its Soviet-made rivals Polikarkov I-15 and I-16 fighters with Werner Mölders, a future WWII ace, scoring 14 victories. This conflict also served to test the new fighter in combat and to detect the shortcomings and needed improvements, as well as to test the Luftwaffe’s tactics and doctrines that would be implemented in WWII. When the conflict came to an end, 40 fighters were gifted to Spain following the withdrawal of the Condor Legion.

The Bf 109 was considered sufficient for the operational needs of Germany until 1941, the year when it would have fulfilled its objectives. However, as the conflict progressed, the high command realized that the Bf 109 needed further upgrades. As a result, the versions Bf 109E, Bf 109F, Bf 109G, and the lesser known Bf 109K were created. Even so, the model’s many shortcomings persisted, putting it at a disadvantage to its rivals.

The Bf 109 had many advantages such as its good range and the powerful engine along with its reasonable size, agility, high speed, climb rate, dive speed, turn rate, maneuverability, and low cost. But there were other problems that prevailed during its service. The struts of the landing gear were rather fragile and narrow, retracting outwards and not beneath the fuselage. Second, Blitzkrieg hindered the fighter’s success as it had to accommodate for the tactic at the expense of autonomy, which would play an important role in the Battle of Britain. This problem was solved after the battle with the addition of extra drop tanks. Third, it tended to swing sideways during landing and takeoff. Fourth, it had a poor lateral control at high speed. Fifth, during combat when executing very close turning, the wings grooves tended to open, preventing stalling but often acting against the ailerons. And sixth, the length and ground angle of the landing gear ‘legs’ was so that it restricted forward visibility while on ground, forcing pilots to taxi in such a way that the undercarriage was put into heavy stress. This posed a problem for rookie pilots. The narrow wheel track also made the fighter unstable while on ground. The solution for this problem was to transfer the load up through the legs while taking off and landing maneuvers.

Approximately 34,000 Bf 109s were built in Germany from 1936 to 1945, in addition to the 239 made by Hispano Aviacion, 75 built in Romania by IAR and 603 made by Avia, with production lasting until 1958. Some 20 Bf 109s remain now as museum displays.

Design

The Messerschmitt Bf 109 is a very interesting fighter with equally interesting design characteristics. Being lightweight was the main concept of its design, development, and construction. It was also a single engine, single seat fighter with a low cantilever wing, whose sleek monocoque fuselage was entirely made out of light-weight metal. Easy access to the powerplant, weaponry at the fuselage, and other systems was considered also as important during design process, and especially when operating from forward airfields. As a result, the engine cowling was made up of large and easily removable panels, with specific panels allowing access to devices such as the fuel tank, the cooling system, and electrical equipment. The devices containing and holding the engine made it easy to remove or replace it as a unit. The power plant tended to differ from version to version: the early versions were powered by a Junkers Jumo 210g inverted V-12 700 hp, with following versions being powered by a Daimler Benz DB 600A with 986 hp and other – more powerful – Daimler Benz engines (for further information, please see the variants). As the engine was inverted, it was reportedly hard to knock out from below. And it also featured an electrical regulator.

The wing was also full of remarkable details. One of them was the main I-beam spar, placed rather aft than usually placed, with the idea of opening space for the retracted wheel, and creating a D-shaped torsion box. This box had more torsional rigidity and also removed the need for a second spar. In addition, the thickness of the wing was slightly varied, with a cord ratio of 14.2% at the root, and a cord ratio of 11.35% at the tip. The wing was also high-loading. Another feature was the introduction of advanced high-lift devices, with automatic leading edge slats and large camber-changing flaps on the trailing edge. These slats increased the lift of the wing, improving horizontal manoeuvrability. Ailerons that drooped slightly when the flaps were lowered were also fitted in the wings, increasing the effective flap area, especially on the F series. The result was an increase on the wings’ lift. As the armament was placed in the fuselage in the earlier versions, the wing was kept very thin and light.

Another remarkable feature, which was standard in the F, G and K versions, were the introduction of two coolant radiators with a cut-off system so to reduce vulnerability of the cooling system after receiving a hit. For instance, if one radiator leaked as a consequence of an impact, the other still made it possible to fly. Even a 5-minute flight was possible with both radiators inoperable.

The canopy of the Bf 109 was a closed bird-cage design, opening sideways and having armour protection plates in the back. These armored plates also protected the main fuel tanks as it was partially placed under the cockpit floor and behind the rear cockpit bulkhead, having an L-shape. Some variants of the G version even featured pressurized cockpits.

In regards to the armament, it tended to vary from version to version in weaponry, caliber, and location. The early versions normally featured an array of two machine guns mounted in the cowling with a 20mm cannon firing through a blast tube between the cylinders. This display was to be changed after the Luftwaffe got a word about the RAF’s plans to equip its new fighters with a battery of 8 guns. This made the additional guns to be installed at the wings, either 7.92mm MG 17 machine guns or a 20mm MG FF or MG FF/M cannon in between the wheel well and slats. The C version featured the additional two 7.92mm machineguns, where a continuous belt was installed to avoid redesigning the wing and ammunition boxes and access hatches. The gun barrel was placed in a tube between the spar and leading edge.

When cannons were installed on the wings, being longer and heavier, they were placed at a farther area in an outer bay, forcing the spar to be cut with holes so to allow feeding the weapon. A small hatch was incorporated to allow access to the gun, which was able to be removed through a removable leading edge panel. The F version and the following versions had the gun changed from the wings to the nose cone, firing through the propeller shaft. Additional 20mm MG 151/20 cannons were installed in pods under the wings, which were easy to install but also forced a reduction of speed by 8 km/h (5 mph). The last version (Bf 109K) was armed with a MK 108 30mm cannon in each wing.

The additional armament, while increasing the Messerschmitt Bf 109’s firepower, also reduced its performance. Handling qualities and dogfighting capabilities were severely affected, with the tendency to swing like a pendulum while flying.

The Reich’s Warrior of the Skies

When the war started in 1939 with the invasion of Poland, around 320 Bf 109s took part in the invasion under two units (I/JG 21 and I/ZG 2). During that operation, the Bf 109s gained air superiority by destroying the Polish air and ground forces, providing escort to ground attack planes and dive bombers, such as the Junkers Ju 87 Stuka. When the invasion of Norway took place, they faced considerable resistance from the outdated Gloster Gladiators of the Norwegian Air Force, which were reinforced by British fighters from HMS Glorious and two more aircraft carriers. During the Battle of France and the invasion of the Netherlands and Belgium, the Messerschmitt Bf 109s encountered weak adversaries. In France, an ill prepared Armee de l’air was unable to face the force of the Luftwaffe while the German fighters gained air supremacy rather quickly and controlled the French skies. Battle of Dunkirk however began to highlight the limitations of the Bf 109, especially in regards to autonomy, as many were coming from bases within Germany and facing strong opposition from the Royal Air Force.

The Battle of Britain was the first battle where the Bf 109 began to show its limitations, especially that of autonomy, having little time to provide effective escort and air supremacy over the British skies. It also found a fitting rival in the Supermarine Spitfire and Hawker Hurricane, which were able to face the Messerschmitt Bf 109 and even were able to overpower it. The radar installations the RAF also played a role in defeating the Bf 109. Moreover, the attrition suffered during the Battle of France took its toll on the Bf 109 that took part in the campaign. As a result, the Luftwaffe – and namely the Bf 109 – was unable to achieve air supremacy and control the skies of Britain, let alone to defeat the RAF, despite the numerical superiority the Luftwaffe had over the RAF (3000 vs. 700 airplanes).

Russia would be a scenario where the fighter would have some redemption, at least in the first stages. As the Soviet Air Force had inferior assets, quality, organization, and training, the Bf 109 achieved an impressive rate of aerial victories (approximately 9200 in total), creating many aces. In addition, the pilots on-board the Bf 109 had already accumulated experience from the previous campaigns – Spain, Poland, Norway, France and England to name a few – while the Bf 109 was comparatively superior to its Soviet-made rivals. However, the superiority in numbers of the Soviet Air Force began to pay its toll on the fighters. It was during this campaign when the fighter was gradually replaced by the more advanced and robust Focke Wulf FW 190 by Summer 1942.

They also took part in the bombing of Malta, with the mission of countering the Spitfires and Fulmar fighters the British managed to sneak onto the island. Although they managed to reduce the losses on the bombers by increasing the attrition of the adversary’s fighters and ground services, the campaign had a considerable cost for the Bf 109 with 400 lost in action. At the same time, the Bf 109 was seeing action in North Africa, achieving air supremacy in the beginning, but facing adverse conditions later on, such as fuel shortages and a superior number of adversaries, alongside attrition imposed by the Luftwaffe’s own organization and training systems.

The Bf 109 also performed as one of the main air defence assets when the Allies began to wage air and bombing campaigns over Germany, targeting mainly the bombers and being benefited by dispersed ammunition and fuel storages all around Germany. The German air industry did not update its models in time or was simply unable to produce fighters enough to tackle the Allies’ air power. As a result, by 1944 the Bf 109 and other fighters were simply unable to counter the Allies’ air campaign. The Bf 109’s career with the Luftwaffe came to an end in 1945, when Germany was defeated.

During and after WWII, the Bf 109 was used by other nations, achieving considerable feats while piloting this aircraft and remaining in service for a long period of time. Finland used the Bf 109 during the Continuation War, claiming a victory ratio of 25:1 and operating with them until 1954. Switzerland received a batch of Bf 109s during the war, using them until 1955. The Bf 109 was donated by Germany and built under license by Spanish air company Hispano Aviacion during and after the war, remaining in service until 1965. Many took part in the film Battle of England. Israel also used Czech-made Bf 109s that fought during the Independence War, scoring 8 victories.

The F-1 was armed with two 7.92 mm MG 17 machineguns and a slow firing 20mm gun firing through the nose and propeller cone. The F-2 as armed with rapid firing two 15mm MG 151s and a 20mm MG FF at the nose. The F-3 was powered with a Daimler Benz DB 601E of 1350 hp, with a rapid firing 20mm gun of and enhanced armour. The F-4 was armed with two 13mm MG 151, a 20mm MG FF, and 15mm MG 151s each on pods under the wing, featuring enhanced armour. The F-5 was lacking the 20mm gun, as it was a reconnaissance fighter. The F-6 had the same mission while having no weapons whatsoever, but reportedly never came to service. The F series normally featured a drop air fuel tank. It was the most advanced in terms of manoeuvrability and aerodynamics.
    • The F-4 had two important sub-variants: F-4/R1, armed with two 20mm MG 151 cannons in underwing gondolas; F-4/Z with a GM-1 boost. There was also a F-4 trop, fitted for service in the tropics.
  • Bf 109GThe most important version with 23,500 fighters built by the end of the war. It was powered by a Daimler Benz DB 605A-1 of 1475 hp, a Daimler Benz DB 605D of 1800 hp with a MW50 injection. It could reach speeds of 469 km/h to 690 km/h. The armament consisted of two 7.92mm MG 17 or two 13mm MG 131 over the engine cowling and a 15mm MG 151 on the G-1 series. The G-2 was powered by the same engine and a similar armament, except that it was armed with the 20mm MG FF cannon. The G-3 and G-4 had the same powerplant anda different radio, the G-3 also having a pressurized cockpit. The G-5 (pressurized fighter) and G-6 were armed with a 20 or 30mm MK 108 at the nose cone, two 15mm MG 151 in the wings. They had a rudder made out of wood. The G-8 was a reconnaissance fighter, the G-10 powered with a Daimler Benz DB 605D of 1850 hp, the G-12 a training version with double controls, two-seat with a tandem cockpit, and the G-15 and G-16, which were enhanced versions of the G-6 and the G-14 respectively. The G-14 was a version armed a 20 mm MG 151 cannon, and two 13 mm MG 131 machineguns, capable of receiving two extra underwing 20mm MG 151 cannons or rocket launcher tubes. Of the G series, many were armed with two 210mm rocket launchpads under the wings or bombs.
    • The G-1 had the G-1/R2 and G-1/U2 sub-variants, a reconnaissance fighter and a high altitude fighter, respectively.

The HA-1109-K1 had a De Havilland Hydromatic propeller, armed with two 20mm cannons and underwing rockets, followed by the HA-1109-K1L. The HA-1112-K1L seemingly featured a three-bladed propeller, powered by a Rolls Royce Merlin engine.
  • HA-1112-M1L BuchonPowered with a Rolls Royce Merlin 500-45 of 1400 hp engine.

Operators

  • Germany – The main builder and user of the Bf 109, being its standard fighter up to 1942, when the Focke Wulf began to steadily replace it as main fighter of the Luftwaffe, mainly in the Russian Front. It served in basically all of the German campaigns during the war, as well as in the defence of Germany against the Allied incursions and the Spanish Civil War. Many famous German aces, such as Werner Mölders, Adolf Galland, and others fought with the Bf 109, scoring most of their victories. Its most excruciating test was at the Battle of Britain, where its limitations became evident, thus being unable to fully control the skies over Britain. On the Russian Front, it scored the largest amount of air and land kills against their Soviet counterparts.
  • Finland – The Scandinavian nation operated 159 Bf 109s after it ordered initially 162 fighters: 48 G – 2s, 11 G-6s and 3 G-8s). Three were destroyed en-route. They were used during the Continuation War, achieving notable feats. The Bf 109s were intended to replace the Fokker D.XXI, Brewster Buffalo and Morane MS-406 fighter Finland had inthose days. Remained in service until 1954.
  • Switzerland – The Swiss Air Force operated 10 D-1s, 83 E-3a variants, 2 F-4s and 14 G-6s, using them to safeguard its neutrality and to fight off many German and Allied airplanes that violated the Swiss air space.
  • Spain – Spain operated D-1s, E-3s, 15 F-4s and possibly B versions of the Bf – 109. A Spanish volunteer detachment – Escuadrilla Azul – operated in Russia in assistance to Germany and operating under German units and command, using E-4, E-7, E-7/B, F-2, F-4, G-4 and G-6 variants. The Hispano Aviacion HA-1112 is the Spanish-built version of the Messerschmitt Bf 109. In service after the war until the mid-Sixties, many Spanish Bf 109s were featured in some WWII movies, such as The Battle of England.
  • Israel – The recently formed Israel Air Force operated the Avia-built version of the Messerschmitt Bf 109, as it bought some fighters from Czech Republic. Operated during the Independence War, it scored 8 kills.
  • Italy – By 1943, a considerable amount of Bf 109s were operated by the Regia Aeronautica, while the established Italian Social Republic after the fall of the fascist government operated 300 G-6s, G-10s, G-14s, 2 G-12s, and three K-4s.
