The Messerschmitt Bf 109 is a German World War II fighter aircraft that was, along with the Focke-Wulf Fw 190, the backbone of the Luftwaffe's fighter force.[3] The Bf 109 first saw operational service in 1937 during the Spanish Civil War and was still in service at the end of World War II in 1945.[3] It was one of the most advanced fighters when it first appeared, with an all-metal monocoque construction, a closed canopy, and retractable landing gear. It was powered by a liquid-cooled, inverted-V12 aero engine.[4] It was called the Me 109 by Allied aircrew and some German aces, even though this was not the official German designation.[5]

The plane was designed by

slave labor
.

The Bf 109 was flown by the three top-scoring fighter aces of all time, who claimed 928 victories among them while flying with Jagdgeschwader 52, mainly on the Eastern Front. The highest-scoring, Erich Hartmann, was credited with 352 victories. The aircraft was also flown by Hans-Joachim Marseille, the highest-scoring ace in the North African campaign who shot down 158 enemy aircraft (in about a third of the time). It was also flown by many aces from other countries fighting with Germany, notably the Finn Ilmari Juutilainen, the highest-scoring non-German ace, who scored 58 of his 94 confirmed victories with the Bf 109. Pilots from Hungary, Romania, Bulgaria, Croatia, and Italy also flew the fighter. Through constant development, the Bf 109 remained competitive with the latest Allied fighter aircraft until the end of the war.[6]

Design and development

Origins

During 1933, the Technisches Amt (C-Amt), the technical department of the

Reichsluftfahrtministerium (RLM) ("Reich Aviation Ministry"), concluded a series of research projects into the future of air combat. The result of the studies was four broad outlines for future aircraft:[7]

  • Rüstungsflugzeug I for a multi-seat medium bomber
  • Rüstungsflugzeug II for a tactical bomber
  • Rüstungsflugzeug III for a single-seat fighter
  • Rüstungsflugzeug IV for a two-seat heavy fighter

Rüstungsflugzeug III was intended to be a short range interceptor, replacing the Arado Ar 64 and Heinkel He 51 biplanes then in service. In late March 1933, the RLM published the tactical requirements for a single-seat fighter in the document L.A. 1432/33.[8]

The projected fighter needed to have a top speed of 400 km/h (250 mph) at 6,000 m (20,000 ft), to be maintained for 20 minutes, while having a total flight duration of 90 minutes. The

"Long Solothurn" ammunition, but was very heavy and had a low rate of fire. It was also specified that the wing loading should be kept below 100 kg/m2. The performance was to be evaluated based on the fighter's level speed, rate of climb, and maneuverability, in that order.[8]

It has been suggested that Bayerische Flugzeugwerke (BFW) was originally not invited to participate in the competition due to personal animosity between Willy Messerschmitt and RLM director Erhard Milch;[nb 1] however, recent research by Willy Radinger and Walter Shick indicates that this may not have been the case, as all three competing companies—Arado, Heinkel and BFW—received the development contract for the L.A. 1432/33 requirements at the same time in February 1934.[8] A fourth company, Focke-Wulf, received a copy of the development contract only in September 1934.[8] The powerplant was to be the new Junkers Jumo 210, but the proviso was made that it would be interchangeable with the more powerful, but less developed Daimler-Benz DB 600 powerplant.[10] Each was asked to deliver three prototypes for head-to-head testing in late 1934.

Prototypes

Design work on Messerschmitt Project Number P.1034 began in March 1934, just three weeks after the development contract was awarded. The basic mock-up was completed by May, and a more detailed design mock-up was ready by January 1935. The RLM designated the design as type "Bf 109", the next available from a block of numbers assigned to BFW.[8]

The first prototype (Versuchsflugzeug 1 or V1), with civilian registration D-IABI, was completed by May 1935, but the new German engines were not yet ready. To get the "R III" designs into the air, the RLM acquired four

Rechlin
to take part in the design competition.

In 1935, the first Jumo engines became available, so V2 was completed in October using the 449 kW (610 PS; 602 hp) Jumo 210A engine. V3 followed, the first to be mounted with guns, but it did not fly until May 1936 due to a delay in procuring another Jumo 210 engine.

Design competition

After Luftwaffe acceptance trials were completed at their headquarters Erprobungsstelle (E-Stelle) military aviation test and development facility at

Rechlin, the prototypes were moved to the subordinate E-Stelle Baltic seacoast facility at Travemünde for the head-to-head portion of the competition. The aircraft participating in the trials were the Arado Ar 80 V3, the Focke-Wulf Fw 159 V3, the Heinkel He 112
V4 and the Bf 109 V2. The He 112 arrived first, in early February 1936, followed by the rest of the prototypes by the end of the month.

Because most fighter pilots of the Luftwaffe were used to biplanes with open

Focke-Wulf Fw 56, was always considered by the E-Stelle Travemünde facility's staff to be a compromise between a biplane and an aerodynamically more efficient, low-wing monoplane. Although it had some advanced features, it used a novel, complex retractable main undercarriage which proved to be unreliable.[11]

Bf 109E-3, c. 1939/1940

Initially, the Bf 109 was regarded with disfavour by E-Stelle test pilots because of its steep ground angle, which resulted in poor forward visibility when taxiing; the sideways-hinged cockpit canopy, which could not be opened in flight (but could be dropped by the emergency arm). They were also concerned about the high wing loading.[12]

The

Blitz, was the favourite of the Luftwaffe leaders. Compared with the Bf 109, it was also cheaper.[13] Positive aspects of the He 112 included the wide track and robustness of the undercarriage (this opened outwards from mid wing, as opposed to the 109s which opened from the wing root
), considerably better visibility from the cockpit and a lower wing loading that made for easier landings. In addition, the V4 had a single-piece, clear-view, sliding cockpit canopy and a more powerful Jumo 210Da engine with a modified exhaust system. However, the He 112 was also structurally complicated, being 18% heavier than the Bf 109, and it soon became clear that the thick wing, which spanned 12.6 m (41 ft 4 in) with an area of 23.2 m2 (249.7 ft2) on the first prototype (V1), was a disadvantage for a light fighter, decreasing the aircraft's rate of roll and manoeuvrability. As a result, the He 112 V4 which was used for the trials had new wings, spanning 11.5 m (37 ft 8.75 in) with an area of 21.6 m2 (232.5 ft2). However, the improvements had not been fully tested and the He 112 V4 could not be demonstrated in accordance with the rules laid down by the Acceptance Commission, placing it at a distinct disadvantage.

Because of its smaller, lighter airframe, the Bf 109 was 30 km/h (20 mph) faster than the He 112 in level flight, and superior in climbing and diving. The Commission ultimately ruled in favour of the Bf 109 because of the Messerschmitt test pilot's demonstration of the 109's capabilities during a series of spins, dives, flick rolls and tight turns, throughout which the pilot was in complete control of the aircraft.[14]

In March, the RLM received news that the British

1936 Berlin Olympics when the V1 prototype was flown.[16]

Design features

As with the earlier Bf 108, the new design was based on Messerschmitt's "lightweight construction" principle, which aimed to minimise the number of separate parts in the aircraft. Examples of this could be found in the use of two large, complex brackets which were fitted to the firewall. These brackets incorporated the lower engine mounts and landing gear pivot point into one unit. A large forging attached to the firewall housed the main spar pick-up points and carried most of the wing loads. Contemporary design practice was usually to have these main load-bearing structures mounted on different parts of the airframe, with the loads being distributed through the structure via a series of strong-points. By concentrating the loads in the firewall, the structure of the Bf 109 could be made relatively light and uncomplicated.[17]

An advantage of this design was that the main landing gear, which retracted through an 85-degree angle, was attached to the

wheel track, making the aircraft unstable while on the ground. To increase stability, the legs were splayed outward somewhat, creating another problem in that the loads imposed during takeoff and landing were transferred up through the legs at an angle.[18]

The small rudder of the Bf 109 was relatively ineffective at controlling the strong swing created by the powerful slipstream of the propeller during the early portion of the takeoff roll, and this sideways drift created disproportionate loads on the wheel opposite to the swing. If the forces imposed were large enough, the pivot point broke and the landing gear leg would collapse outward into its bay.[18] Experienced pilots reported that the swing was easy to control, but some of the less-experienced pilots lost fighters on takeoff.[19]

Because of the large ground angle caused by the long legs, forward visibility while on the ground was very poor, a problem exacerbated by the sideways-opening canopy. This meant that pilots had to taxi in a sinuous fashion which also imposed stresses on the splayed undercarriage legs. Ground accidents were a problem with inexperienced pilots, especially during the later stages of the war when pilots received less training before being sent to operational units.[19] At least 10% of all Bf 109s were lost in takeoff and landing accidents, 1,500 of which occurred between 1939 and 1941.[20] The installation of a fixed "tall" tailwheel on some of the late G-10s and −14s and the K-series helped alleviate the problem to a large extent.[21]

From the inception of the design, priority was given to easy access to the powerplant, fuselage weapons and other systems while the aircraft was operating from

Kraftei
engine mounting concept used by many German combat aircraft designs, later in the war years.

Another example of the Bf 109's advanced design was the use of a single, I-beam main

chord
ratio of 14.2% at the root and 11.35% at the tip.

Another major difference from competing designs was the higher wing-loading. While the R-IV contract called for a wing-loading of less than 100 kg/m2, Messerschmitt felt this was unreasonable. With a low wing-loading and the engines available, a fighter would end up being slower than the bombers it was tasked with catching.[citation needed]

A fighter was designed primarily for high-speed flight. A smaller wing area was optimal for achieving high speed, but low-speed flight would suffer, as the smaller wing would require more airflow to generate enough lift to maintain flight. To compensate for this, the Bf 109 included advanced

flaps on the trailing edge. The slats increased the lift of the wing considerably when deployed, greatly improving the horizontal maneuverability of the aircraft, as several Luftwaffe veterans, such as Erwin Leykauf, attest.[23][24]
Messerschmitt also included ailerons that "drooped" when the flaps were lowered (F series and later the lower radiator flap operated as part of the flap system), thereby increasing the effective flap area. When deployed, these devices effectively increased the wings' coefficient of lift.

Fighters with liquid-cooled engines were vulnerable to hits in the cooling system. For this reason, on later Bf 109 F, G and K models, the two coolant radiators were equipped with a cut-off system. If one radiator leaked, it was possible to fly on the second or to fly for at least five minutes with both closed.[25][26][27][28] In 1943, Oberfeldwebel Edmund Roßmann got lost and landed behind Soviet lines. He agreed to show the Soviets how to service the plane. Soviet machine gun technician Viktor M. Sinaisky recalled:

The Messer was a very well designed plane. First, it had an engine of an inverted type, so it could not be knocked out from below. It also had two water radiators with a cut-off system: if one radiator leaked you could fly on the second or close both down and fly at least five minutes more. The pilot was protected by armour-plate from the back, and the fuel tank was also behind armour. Our planes had fuel tanks in the centre of their wings: that's why our pilot got burnt. What else did I like about the Messer? It was highly automatic and thus easy to fly. It also employed an electrical pitch regulator, which our planes didn't have. Our propeller system, with variable pitch was hydraulic, making it impossible to change pitch without engine running. If, God forbid, you turned off the engine at high pitch, it was impossible to turn the propeller and was very hard to start the engine again. Finally, the German ammo counter was also a great thing.[28]

Armament and gondola cannons

Reflecting Messerschmitt's belief in low-weight, low-drag, simple monoplanes, the armament was placed in the fuselage. This kept the wings very thin and light. Two synchronized machine guns were mounted in the cowling, firing over the top of the engine and through the propeller arc. An alternative arrangement was also designed, consisting of a single autocannon firing through a blast tube between the cylinder banks of the engine, known as a Motorkanone mount in German.[7][nb 3] This was also the choice of armament layout on some contemporary monoplane fighters, such as the French Dewoitine D.520, or the American Bell P-39 Airacobra, and dated back to World War I's small run of SPAD S.XII moteur-canon, 37 mm cannon-armed fighters in France.

When it was discovered in 1937 that the RAF was planning eight-gun batteries for its new Hawker Hurricane and Supermarine Spitfire fighters, it was decided that the Bf 109 should be more heavily armed. The problem was that the only place available to mount additional guns was in the wings. Only one spot was available in each wing, between the wheel well and slats, with room for only one gun, either a 7.92 mm MG 17 machine gun, a 20 mm MG FF or a 20 mm MG FF/M cannon.[30]

The first version of the Bf 109 to have wing guns was the C-1, which had one MG 17 in each wing. To avoid redesigning the wing to accommodate large ammunition boxes and access hatches, an unusual ammunition feed was devised whereby a continuous belt holding 500 rounds was fed along chutes out to the wing tip, around a roller, and then back along the wing, forward and beneath the gun breech, to the wing root, where it coursed around another roller and back to the weapon.[30]

The gun barrel was placed in a long, large-diameter tube located between the spar and the leading edge. The tube channeled cooling air around the barrel and breech, exhausting from a slot at the rear of the wing. The installation was so cramped that parts of the MG 17's breech mechanism extended into an opening created in the flap structure.[30]

The much longer and heavier MG FF had to be mounted farther along the wing in an outer bay. A large hole was cut through the spar allowing the cannon to be fitted with the ammunition feed forward of the spar, while the breech block projected rearward through the spar. A 60-round ammunition drum was placed in a space closer to the wing root causing a bulge in the underside. A small hatch was incorporated in the bulge to allow access for changing the drum. The entire weapon could be removed for servicing by removing a leading edge panel.[30]

From the 109F-series onwards, guns were no longer carried inside the wings. Instead, the Bf 109F had a 20 mm gun firing through the propeller shaft. The change was disliked by leading fighter pilots such as Adolf Galland and Walter Oesau, but others such as Werner Mölders considered the single nose-mounted gun to compensate well for the loss of the two wing guns.[31] Galland had his Bf 109F-2 field-modified with a 20 mm MG FF/M autocannon, the "/M" suffix indicating the capability of firing thin-walled 20mm mine shells, installed internally in each wing.[nb 4]

In place of internal wing armament, additional firepower was provided through a pair of 20 mm MG 151/20 cannons installed in conformal gun pods under the wings. The conformal gun pods, exclusive of ammunition, weighed 135 kg (298 lb);[32] and 135 to 145 rounds were provided per gun. The total weight, including ammunition, was 215 kg.[32] Installation of the under-wing gun pods was a simple task that could be quickly performed by the unit's armourers, and the gun pods imposed a reduction of speed of only 8 km/h (5.0 mph).[32] By comparison, the installed weight of a similar armament of two 20 mm MG 151/20 cannon inside the wings of the Fw 190A-4/U8 was 130 kg (287 lb), without ammunition.[33]

Although the additional armament increased the fighter's potency as a bomber destroyer, it had an adverse effect on the handling qualities, reducing its performance in fighter-versus-fighter combat and accentuating the tendency of the fighter to swing pendulum-fashion in flight.[31][34]

Some of the projected 109K-series models, such as the K-6, were designed to carry 30 mm (1.18 in) MK 108 cannons in the wings.[35]

Designation and nicknames

Originally the aircraft was designated as Bf 109 by the RLM, since the design was submitted by the Bayerische Flugzeugwerke (literally "Bavarian Aircraft Works", meaning "Bavarian Aircraft Factory"; sometimes abbreviated B.F.W.,[36] akin to BMW) during 1935. The company was renamed

Messerschmitt AG after 11 July 1938 when Erhard Milch finally allowed Willy Messerschmitt to acquire the company. All Messerschmitt aircraft that originated after that date, such as the Me 210, were to carry the "Me" designation. Despite regulations by the RLM, wartime documents from Messerschmitt AG, RLM and Luftwaffe loss and strength reports continued to use both designations, sometimes even on the same page.[37]

All extant airframes bear the official[5] "Bf 109" designation on their identification plates, including the final K-4 models.[38] The aircraft was often referred to by the folk-designation, 'Me 109', particularly by the Allies.

The aircraft was often nicknamed Messer by its operators and opponents alike; the name was not only an abbreviation of the manufacturer but also the German word for "knife". In Finland, the Bf 109 was known as Mersu, although this was originally (and still is) the Finnish nickname for Mercedes-Benz cars.

Soviet aviators nicknamed the Bf 109 "the skinny one" (худо́й, khudoy), for its sleek appearance compared, for example, to the more robust Fw 190.

The names "Anton", "Berta", "Caesar", "Dora", "Emil", "Friedrich", "Gustav", and "Kurfürst" were derived from the variant's official letter designation (e.g. Bf 109G – "Gustav"), based on the

German spelling alphabet of World War II, a practice that was also used for other German aircraft designs.[39] The G-6 variant was nicknamed by Luftwaffe personnel as Die Beule ("the bump/bulge") because of the cowling's characteristic, bulging covers for the breeches of the 13 mm (.51 in) MG 131 machine guns
, with the separate Beule covers eliminated by the time of the G-10 model's introduction of a subtly reshaped upper cowling.

Record-setting flights

Bf 109G-10 (Messerschmitt foundation) flight demonstration

In July 1937, not long after the public debut of the new fighter, three Bf 109Bs took part in the Flugmeeting airshow in Zürich under the command of Major Seidemann. They won in several categories: First prize in a speed race over a 202 km course, first prize in the class A category in the international Alpenrundflug for military aircraft, and victory in the international Patrouillenflug category.[16]

On 11 November 1937, the Bf 109 V13, D-IPKY flown by Messerschmitt's chief pilot Dr. Hermann Wurster, powered by a 1,230 kW (1,672 PS; 1,649 hp) DB 601R racing engine, set a new world air speed record for landplanes with piston engines of 610.95 km/h (379.63 mph), winning the title for Germany for the first time. Converted from a Bf 109D, the V13 had been fitted with a special racing DB 601R engine that could deliver 1,230 kW (1,672 PS; 1,649 hp) for short periods.[40][41][nb 5]

He 100. On 6 June 1938, the He 100 V3, flown by Ernst Udet, captured the record with a speed of 634.7 km/h (394.4 mph). On 30 March 1939, test pilot Hans Dieterle surpassed that record, reaching 746.61 km/h (463.92 mph) with the He 100 V8. Messerschmitt, however, soon regained the lead when, on 26 April 1939, Flugkapitän Fritz Wendel, flying the Me 209 V1, set a new record of 755.14 km/h (469.22 mph). For propaganda purposes, the Me 209 V1 aircraft (possibly from its post-July 1938 first flight date) was given the designation Me 109R, with the later prefix, never used for wartime Bf 109 fighters.[5] The Me 209 V1 was powered by the DB 601ARJ, producing 1,156 kW (1,550 hp), but capable of reaching 1,715 kW (2,300 hp). This world record for a piston-engined aircraft was to stand until 1969,[42] when Darryl Greenamyer's modified Grumman F8F Bearcat, Conquest I, broke it with a 777 km/h (483 mph) record speed.[43]

Variants

Bf 109E-3 in flight, 1940

When the Bf 109 was designed in 1934, by a team led by

Jumo 210 series engines. A few prototypes of these early aircraft were converted to use the more powerful DB 600.[48]

The first redesign came with the E series, including the naval variant, the Bf 109T (T standing for Träger, carrier). The Bf 109E (Emil) introduced structural changes to accommodate the heavier and more powerful 1,100 PS (809 kW; 1,085 hp) Daimler-Benz DB 601 engine, heavier armament and increased fuel capacity. Partly due to its limited 300 kilometres (190 miles) combat radius on internal fuel alone, resulting from its 660 km (410 mi) range limit, later variants of the E series had a fuselage ordnance rack for fighter-bomber operations or provision for a long-range, standardized 300 litres (79 US gallons) drop-tank and used the DB 601N engine of higher power output.[5][49] The Bf 109E first saw service with the "Condor Legion" during the last phase of the Spanish Civil War and was the main variant from the beginning of World War II until mid-1941 when the Bf 109F replaced it in the pure fighter role.[50] (Eight Bf 109Es were assembled in Switzerland in 1946 by the Dornier-Werke, using licence-built airframes; a ninth airframe was assembled using spare parts.)[51]

The second big redesign during 1939–40 gave birth to the

lift strut on either side of the tail. The improved aerodynamics were used by all later variants. Some Bf 109Fs were used late in the Battle of Britain in 1940 but the variant came into common use only in the first half of 1941.[52]

The

superchargers, boosting engine output to 1,800–2,000 PS (1,324–1,471 kW; 1,775–1,973 hp). From early 1944, some G-2s, G-3s, G-4s and G-6s were converted to two-seat trainers, known as G-12s. An instructor's cockpit was added behind the original cockpit and both were covered by an elongated, glazed canopy.[53]

The final production version of the Bf 109 was the K series or Kurfürst, introduced in late 1944, powered by the DB 605D engine with up to 2,000 PS (1,471 kW; 1,973 hp). Though externally akin to the late production Bf 109G series, a large number of internal changes and aerodynamic improvements were incorporated that improved its effectiveness and remedied flaws, keeping it competitive with the latest Allied and Soviet fighters.[6][54] The Bf 109's outstanding rate of climb was superior to many Allied adversaries including the P-51D Mustang, Spitfire Mk. XIV and Hawker Tempest Mk. V.[55]

After the war, the 109 was built in

Ha 1112.[56]

Production

Assembly of Bf 109G-6s in a German aircraft factory.

Total Bf 109 production was 33,984 units;[2] wartime production (September 1939 to May 1945) was 30,573 units. Fighter production totalled 47% of all German aircraft production, and the Bf 109 accounted for 57% of all German fighter types produced.[57] A total of 2,193 Bf 109 A–E was built prewar, from 1936 to August 1939.[citation needed]

In January 1943, as part of an effort to increase fighter production, Messerschmitt licensed an SS-owned company,

DEST, to manufacture Bf 109 parts at Flossenbürg concentration camp. Messerschmitt provided skilled technicians, raw materials, and tools and the SS provided prisoners, in a deal that proved highly profitable for both parties. Production at Flossenbürg started in February.[58] The number of prisoners working for Messerschmitt increased greatly after the bombing of Messerschmitt's Regensburg plant on 17 August 1943.[59] Erla, a subcontractor of Messerschmitt, established Flossenbürg subcamps to support its production: a subcamp at Johanngeorgenstadt, established in December 1943, to produce tailplanes for the Bf 109, and another subcamp at Mülsen-St. Micheln which produced Bf 109 wings, in January 1944.[60] The Flossenbürg camp system had become a key supplier of Bf 109 parts by February 1944, when Messerschmitt's Regensburg plant was bombed again during "Big Week". Increased production at Flossenbürg was essential to restoring production in the aftermath of the attacks.[60]

The Austrian resistance group, led by Heinrich Maier, very successfully passed on plans and production facilities in the Austrian area for Messerschmitt Bf 109 to the Allies from 1943. With the location of the production sites, the Allied bombers were able to attempt "precise" air strikes.[61][62][63][64]

After the August 1943 Regensburg raid, some Bf 109 production was relocated to

Buchenwald produced approximately 300 Bf 109 fuselages, tail sections, and wings before the end of the war.[69]

Some 865 Bf 109G derivatives were manufactured postwar under licence as Czechoslovak-built Avia S-99 and S-199s, with the production ending in 1948.[3] Production of the Spanish-built Hispano Aviación HA-1109 and HA-1112 Buchons ended in 1958.[3]

Operational history

Bf 109A from the Condor Legion during Spanish Civil War (1936–1939)

The first Bf 109As served in the

USSR) and the Siege of Malta
.

In 1942, it began to be partially replaced in Western Europe by a new German fighter, the

Afrikakorps
. It was also supplied to several of Germany's allies, including Italy, Finland, Hungary, Romania, Bulgaria, Croatia and Slovakia.

More aerial kills were made with the Bf 109 than any other aircraft of World War II.[77] Many of the aerial victories were accomplished against poorly trained and badly organized Soviet forces in 1941 during Operation Barbarossa. The Soviets lost 21,200 aircraft at this time, about half to combat.[78] If shot down, the Luftwaffe pilots might land or parachute to friendly territory and return to fight again. Later in the war, when Allied victories began to bring the fight closer, and then in German territory, bombing raids supplied plenty of targets for the Luftwaffe. This unique combination of events — until a major change in American fighter tactics occurred very early in 1944, that steadily gave the Allies daylight air supremacy over the Reich — led to the highest-ever individual pilot victory scores.[79] One hundred and five Bf 109 pilots were each credited with the destruction of 100 or more enemy aircraft.[nb 15] Thirteen of these men scored more than 200 kills, while two scored more than 300. Altogether, this group of pilots was credited with a total of nearly 15,000 kills.[77] Though no official "ace" status existed in the Luftwaffe - the term Experte (expert) was used for an experienced pilot irrespective of his number of kills - using the Allied definition of pilots who scored five or more kills, more than 2,500 Luftwaffe fighter pilots were considered aces in World War II.[80] Against the Soviets, Finnish-flown Bf 109Gs claimed a victory ratio of 25:1.[81]

Bf 109s remained in foreign service for many years after World War II. The Bf109 was the first aircraft deployed in the first years of the Israeli Air Force. The Swiss used their Bf 109Gs well into the 1950s. The Finnish Air Force did not retire their Bf 109Gs until March 1954. Romania used its Bf 109s until 1955. The Spanish Hispanos flew even longer. Some were still in service in the late 1960s. They appeared in films (notably Battle of Britain) playing the role of Bf 109Es. Some Hispano airframes were sold to museums, which rebuilt them as Bf 109s.

Operators

Note, this list includes operators who used Bf 109s for active service or combat. It does not include France, the Soviet Union, the United Kingdom, and the United States, which all operated small numbers of captured aircraft for testing and evaluation (see: Messerschmitt Bf 109 operational history#Allied Bf 109s).

  • Czechoslovak Air Force operated captured aircraft and continued building Messerschmitt Bf 109Gs after the war under the Avia S-99 name, but soon ran out of the 109's Daimler-Benz DB 605 engine after many were destroyed during an explosion at a warehouse in Krásné Březno.
 Finland
  • Finnish Air Force ordered 162 aircraft (48 G-2s, 111 G-6s and three G-8s) from Germany, but 3 were destroyed during transit, leaving the FAF with 159 Bf 109s. FAF pilots had 663 air victories during 1943–44 with Bf 109 G's and lost 34 in combat (20 shot down by enemy aircraft). 23 were non-combat losses and other write-offs. 102 Bf 109 G survived the war.
 Greece – (captured)
  • Royal Hellenic Air Force
    operated a number of captured G-6 109s which had been left during the German withdrawal in October 1944
