Development of Willi Messerschmitt's famous Bf 109 began in 1933, when the Reichsluftministerium (RiM) issued a requirement for a new monoplane fighter. The prototype B1 109V-1 flew for the first time in September 1935, powered by a 695hp Rolls-Royce Kestrel engine, as the 610hp Junkers Jumo 210A which was intended for it was not yet available. The Bf 109V-7, armed with two machine guns and a single MG FF (0.79-in (20-mm) Oerlikon cannon), became the prototype for the first series production model, the Bf 109B, powered by a 610hp Jumo 210 engine. Three of the Bf 109 prototypes were evaluated in Spain in February and March 1937 and were followed by 24 Bf 109B-2s, which immediate- ly proved superior to any other fighter engaged in the civil war. It was the use of the Bf 109 in Spain that enabled the Luftwaffe to develop the fighter tactics that would enable it to wreak havoc among its opponents in the early years of World War II.

By the time that conflict began in September 1939,1,060 Bf 109s of various subspecies were in service with the Luftwaffe's fighter units. These included the Bf 109C and Bf 109D, which were already being replaced by the Bf 109£ series; this model was to be the mainstay of the Luftwaffe's fighter units throughout 1940. The series extended to the £-9, including models built as fighters, fighter-bombers, and reconnaissance aircraft. Ten Bf 109£s were converted for operations from Germany's planned aircraft carrier, the Graf Zeppelin, under the designation Bf 109T. The best of all Bf 109 variants, the Bf 109F, began to reach Luftwaffe units in France in May 1941 and was superior in most respects to the principal RAF fighter of the time, the Spitfire Mk V. The Bf 109F differed from the Bf 109£ in having a generally cleaned- up airframe, redesigned engine cowling, wing, radiators, and tail assembly. It was succeeded by the Bf 109G, which appeared late in 1942. Preproduction Bf 109G-0 aircraft retained the DB 601£ of the F series, but the first production model, the Bf 109G-1, had the more powerful DB 605A engine. The G-1, G-3, and G-5 had provision for pressurized cockpits and were fitted with the GM-1 emergency power- boost system, which was lacking in the G-2 and G-4. Various armament combinations were employed, and later aircraft were fitted with wooden tail units. The fastest G model, the Bf 109G-10, without wing armament and with MW 50 power- boost equipment, reached a maximum speed of 425mph (687km/h) at 24,278ft (7,400m), climbed to 20,000ft (6,100m) in six minutes and had an endurance of 55 minutes.

The last operational versions of the Bf 109 were the K -4 and K-6, which both had DB 605D engines with MW 50 power boost. The Bf 109K-4 had two 0.58-in (15-mm) MG 151 guns semi externally mounted above the engine cowling and a 0.79- in (20-mm) MK 108 or 1.19-in (30-mm) Mk 103 firing through the propeller hub. The Bf 109K-6 had the cowling-mounted MG 151s replaced by 0.50-in (12.7-mm) MG 131 machine guns and had two 1.19-in (30-mm) MK 103 cannon in under- wing gondolas. The last variant was the Bf 109K-14, with a DB 605L engine, but only two examples saw service with JG 52.

The Bf 109G was built in both Spain (as the Hispano Ha- 1109) and Czechoslovakia (as the Avia S-199). Some of the Czech-built: aircraft were acquired by Israel in 1948. Bf 109 production reached an approximate total of 35,000 aircraft.
