Messerschmitt Bf 109 — Fighter
Open in interactive gallery →

The Messerschmitt Bf 109 is a German single-seat fighter aircraft designed by Willy Messerschmitt at Bayerische Flugzeugwerke (later Messerschmitt AG) and produced from 1937 to 1958. With approximately 33,984 airframes built across 14 main variants — making it the most-produced fighter aircraft of all time — the Bf 109 was the principal Luftwaffe single-engine fighter of the Second World War and the platform on which most Luftwaffe aces flew.

The Bf 109 entered Luftwaffe service in February 1937, three months before the Spanish Civil War began. The aircraft was the first all-metal monocoque single-seat fighter with retractable landing gear, enclosed cockpit, and (in early variants) high-wing-loading aerodynamics that gave it impressive top-speed and dive performance. Initial Bf 109B / C variants used the Junkers Jumo 210 inverted V-12; the Bf 109E ("Emil", entering service 1939) used the Daimler-Benz DB 601 fuel-injected engine producing 1,100 hp — a critical advantage over the Spitfire and Hurricane in negative-g manoeuvres until the Allies adopted fuel-injection in the 1942-1943 timeframe.

The Bf 109's combat record spans the entire WWII period and beyond. Major variants included the Bf 109E (Battle of Britain, North Africa), the Bf 109F ("Friedrich", 1941-1942 — considered by many pilots the most refined variant), the Bf 109G ("Gustav", the most-produced variant with ~30,000 built), and the late-war Bf 109K ("Kurfürst"). Performance varied substantially across marks: peak top speeds of 397 mph (Bf 109K-4) at altitude. Armament progressed from 4 × 7.92mm MG 17 (Bf 109E-1) to mixed cannon-and-machine-gun fits (the standard Bf 109G fit was 1 × 20mm MG 151/20 nose cannon + 2 × 13mm MG 131 cowl-mounted machine guns + 2 × 20mm MG 151/20 wing cannon in some variants).

The Bf 109 was the principal Luftwaffe fighter in every major WWII theatre — the Battle of Britain, North Africa, the Mediterranean, the Eastern Front (where it scored an enormous proportion of total kills), and the Defence of the Reich. The leading Luftwaffe ace, Erich Hartmann, scored all 352 of his kills in Bf 109 variants — the highest individual fighter-pilot total in history. Post-WWII, Spain, Czechoslovakia, Switzerland, and Israel all operated Bf 109 derivatives (the Spanish HA-1112 "Buchón" and Czech Avia S-99 / S-199 "Mezec"). The HA-1112 was Rolls-Royce Merlin-powered (Spain couldn't source DB 605 engines after WWII), making it visually distinctive and frequently used in Spitfire-versus-Bf 109 movie sequences. Approximately 30 Bf 109 / HA-1112 / S-199 airframes remain airworthy in 2026 across private and museum collections.

For Kids — a shorter, friendlier version

The Messerschmitt Bf 109 was Germany's main fighter plane in World War II. It was small, fast, and tough. About 34,000 of them were built — more than any other fighter in history. The Bf 109 was the airplane German pilots flew while attacking other countries, and it was the main rival of the British Spitfire during the Battle of Britain.

The Bf 109 was designed by Willy Messerschmitt in the 1930s. The plane is about 29 feet long — smaller than a school bus. Its body was slim and shaped like a shark, with thin wings and a powerful V-12 Daimler-Benz engine in the nose. Different versions had different guns: some had two machine guns, others had a cannon firing through the propeller shaft. Top speed was about 380 mph, similar to the Spitfire.

The Bf 109's biggest weakness was its narrow landing gear. The wheels were so close together that the plane easily tipped over during landings on uneven ground. Around 10% of all Bf 109s ever built were lost in landing accidents — more than were ever lost in combat. German pilots had a love-hate relationship with the plane.

About 34 different versions of the Bf 109 were built between 1936 and 1958. Spain built some of its own version (the Hispano Aviación HA-1112) and used them all the way until 1965. Today about 15 Bf 109s still fly. Many movies set during World War II use modified Spanish HA-1112s as stand-ins, painted with German markings.

Kids’ Questions

Why did the Bf 109 land badly?

The Bf 109's main landing gear came out of the fuselage instead of out of the wings. This meant the two wheels were very close together when the plane was on the ground. Imagine trying to balance on a bicycle with the wheels two inches apart instead of normal — that's how unstable the Bf 109 felt. Crosswinds, bumpy runways, or even just a careless pilot could cause the plane to tip onto its wing. After WWII, Spain redesigned the Bf 109's landing gear, and the problem mostly went away.

Was the Bf 109 better than the Spitfire?

It is a classic debate. The Bf 109 was lighter and accelerated faster. The Spitfire turned better and was easier to land. Each had advantages depending on the version and the altitude. In the Battle of Britain (1940), both were closely matched, and the result depended more on tactics and pilot skill than on the planes themselves. Most aviation historians today say they were roughly equal — but each had its favorite fans.

Notable Operators

Luftwaffe (Nazi Germany)
Principal operator. Bf 109 served on every WWII front — Battle of Britain, North Africa, Mediterranean, Eastern Front, Defence of the Reich. Approximately 14,000 Luftwaffe pilots claimed Bf 109 victories; the type accounts for the majority of WWII Luftwaffe kills.
Foreign WWII operators
Italy (Regia Aeronautica), Hungary, Romania, Bulgaria, Slovakia, Finland, Croatia, Spain (Nationalist forces) — various Bf 109 marks supplied or licence-built. Switzerland operated Bf 109E / D from 1939 (purchased pre-war).
Post-WWII operators
Spain (HA-1112 Buchón, 1956-1965), Czechoslovakia (Avia S-99 / S-199, 1945-1957), Israel (purchased 25 S-199 from Czechoslovakia 1948 — the IAF's first fighters during the 1948-1949 War of Independence), Yugoslavia (Avia S-99).
Civilian / preservation
Approximately 30 Bf 109 / HA-1112 / S-199 airframes remain airworthy in 2026, mostly Spanish HA-1112 Buchón variants (Merlin-powered). Used in WWII movie productions including Battle of Britain (1969), Memphis Belle (1990), and many subsequent films.

Frequently Asked Questions

How does the Bf 109 compare to the Spitfire?

Both were the principal single-engine fighters of the Battle of Britain and were broadly equivalent in performance, though with different strengths. The Bf 109E had higher dive speed, better high-altitude performance, and a fuel-injected engine that worked under negative g (the early Spitfire's Merlin had a carburettor that briefly cut out under negative g until 1941). The Spitfire had a tighter turn radius, better roll rate at low speed, and better visibility. The two aircraft were broadly evenly matched; pilot quality and tactical situation generally determined outcomes. Later Spitfire marks (Mk IX onwards) progressively pulled ahead in performance, though late Bf 109 marks (G-10, K-4) closed the gap.

Why is it called the "Bf 109" rather than "Me 109"?

Originally designed at Bayerische Flugzeugwerke (BFW), the company was renamed Messerschmitt AG in 1938 (after Willy Messerschmitt became chief designer / managing director). RLM (German Air Ministry) designations issued before the renaming retained the "Bf" prefix; later types (Bf 110 already issued, then Me 210, Me 262, Me 410, Me 163, etc.) used "Me." The Bf 109 designation was therefore a legacy of the company's pre-1938 name. In wartime German use both "Bf 109" and "Me 109" appeared interchangeably; modern technical / collector usage usually preserves "Bf 109."

How many Bf 109s were built?

33,984 Bf 109 airframes were built between 1936 and 1945 across 14 main variants — the most-produced fighter aircraft of all time. Production took place across multiple factories including Regensburg, Wiener Neustadt, Augsburg, Erla in Leipzig, and dispersed sub-contractor sites. Including post-war Spanish HA-1112 (~239) and Czech S-99 / S-199 (~600), total production exceeds 34,800.

Who was Erich Hartmann?

The leading Luftwaffe fighter ace of WWII and the highest-scoring fighter pilot in history, with 352 confirmed aerial victories. Hartmann flew exclusively Bf 109 variants throughout his combat career on the Eastern Front (Jagdgeschwader 52, JG 52). All of his victories were against Soviet aircraft. He was captured by Soviet forces in May 1945 and held for 10 years; on release he returned to Germany, served in the post-war Bundeswehr Luftwaffe (West German Air Force), and retired as a Major. He is buried at Friedhof Weil im Schönbuch.

What is the HA-1112 Buchón?

The Spanish post-war Bf 109 derivative — Bf 109G airframes built under licence in Spain at Hispano Aviación. The original DB 605 engines were unavailable after WWII, so Spanish HA-1112 Buchón (1956-1965) used Rolls-Royce Merlin 500 engines, giving the aircraft a distinctive bulged cowling and propeller spinner. The HA-1112 served the Spanish Air Force into the 1960s and is the dominant survivor in modern airworthy collections — most "flying Bf 109s" today are HA-1112 Buchones with Merlin engines, since original DB 605s are extremely rare and difficult to maintain.

What are the surviving Bf 109s?

Approximately 30 airworthy aircraft globally, plus ~50-70 static museum airframes. The Imperial War Museum Duxford, the RAF Museum, the National WWII Museum (New Orleans), the Smithsonian National Air and Space Museum, and the Deutsches Museum (Munich) all hold significant Bf 109 / HA-1112 collections. Major restoration projects continue at the Erickson Aircraft Collection, the Old Flying Machine Company (UK), and several private operators. Surviving original DB 605-powered Bf 109s are extremely rare; most operating airframes are Merlin-powered HA-1112 conversions.
