The Bf 109 saw active service in many air forces and was active in several conflicts outside of World War II. Soviet-history of operational research pdf aircraft in mid 1937 as a testing ground for the new German fixed-wing fighter plane.

12 months of the conflict. 136 Bf 109s were sent to Spain, and 47 of these, including Bf 109Bs, Ds and Es remained behind in service with the Spanish Air Force after the conclusion of the war in 1939. Republican forces suffered heavy losses to Nationalist and Condor Legion fighters. As many as 20 Bf 109s were lost in Spain to enemy action to both aerial combat and ground fire. The Bf 109 was credited with more aerial kills than any other aircraft. Bf 109 pilots were credited with the destruction of 100 or more enemy aircraft. Thirteen of these men scored more than 200 kills, while two scored more than 300.

Altogether this group were credited with nearly 15,000 kills between them. Among many of the combatants, ace status was granted to a pilot who scored five or more kills. 2,500 German pilots were aces. Between January and October 1942, a further 18 German pilots joined the select group that had now reached 100 kills over the Eastern Front. During this period Bf 109 pilots claimed 12,000 Soviet aircraft destroyed. The E-1 and E-4 variants bore the brunt of the battle. 375 E-1s, 125 E-3s, 339 E-4s and 32 E-7s on strength, indicating that most of the E-3s had been already converted to E-4 standard.

The Bf 109s thus had the initial advantage in dives, either during attack or to escape, in that it could ‘bunt’ directly into a dive with no loss of power. The MG FFs had a relatively small ammunition supply compared to the machine guns, each being fed by a 60-round capacity drum magazine. Making up about one-third of the Bf 109Es in the Battle, the E-1s, carried an all-machine gun armament of four 7. MG 17 machine guns, but were provided with a total of 4,000 rounds. It was advised not to engage in turning dogfights unless the performance advantage of the Bf 109 could be used to full effect.

The roll rate of the Bf 109 was deemed superior, as was its stability on target approach. During the Battle of Britain, the Bf 109’s chief disadvantage was its short range: like most of the 1930s monoplane interceptors, it was designed to engage enemy bombers over friendly territory, and the range and endurance necessary for escorting long-ranged bombers over enemy territory was not required. British target, had only 10 minutes of flying time before turning for home, leaving the bombers undefended by fighter escorts. 28 Fw 190s were not delivered until November 1940. The ordnance rack was not retrofitted to earlier Bf 109Es until October 1940. The Spitfire and Hurricane, designed with similar operational requirements in mind, had a tactical advantage as they were operating virtually over their home airfields as interceptors, and thus being able to remain longer in the combat area. 160 new bombers and 758 new fighters from their own production lines, while losing about 1,600 aircraft in combat, for accidents and other causes.

For this reason, the Italian Air Force decided to use German aircraft. Most of them were destroyed by Allied bombers. Rome with the last three remaining Bf 109s arriving from Sicily. Sicily, directed that the Fiat G. 29 May, and two G-12 trainers were delivered two weeks later. By 22 June, the unit was ready for its first operations.

Bf 109s sortied from the airfield, although nothing was achieved. C continued to use a combination of Macchi 205s and Fiat G. August 1944 through to December, when the first Bf 109 G-12 trainer arrived. Germany to convert to the Messerschmitts. G-6s, G-10s and K-4s, most of which came directly from Germany, were available at the end of the month. The first combat operation occurred on 14 March 1945. At this stage, Luftwaffe ordered ANR pilots to operate outside Italian borders.

They operated together with German pilots against an Allied bomber raid. During this combined mission eight B-24 Liberators were shot down. P-47Ds of 347 Fighter Squadron. In the air battle that ensued, ANR pilots suffered a heavy defeat: 14 Bf 109s were shot down and six Italian pilots killed, without scoring a single air victory.

Forlani claimed a P-47 damaged, but the other two Italian fighters were hit and lightly damaged. Asso di bastoni” had its last combat, last claim and its last loss. 52 on the Eastern Front, the first Hungarian fighter unit to convert to the Bf 109 F-4 was the RHAF’s 1. Home Air Defense with Bf 109s. During ‘The American Season’, between May and August 1944, the 101.
