The Messerschmitt Bf-109G "Gustav" and the earlier Battle of Britain Messerschmitt Bf-109E "Emil" are probably the best known models of this remarkable WW2 fighter. The Messerschmitt Bf-109g fighter was a logical progression of the Bf-109 design which was necessary to keep pace with the latest Spitfire's and Mustang P-51's allied fighters. The Messerschmitt Bf-109G "Gustav" entered service with the Luftwaffe in mid 1942, it was the most numerous model of the Bf-109 WWII fighter produced. Built around the new 1,475 hp Daimler-Benz DB 605 engine and incorporating greater firepower in the form of 13 mm MG 131 machine guns giving this WW2 fighter it's notorious twin bulges and the resultant nickname the "Die Beule" ("The Bulge"). Initially problems with the new engine resulted in the engines power having to be restricted to 88% in order to improve reliability. 
The fastest of the Messerschmitt Bf-109G variants was the Daimler-Benz DB 605D powered Messerschmitt Bf 109G-10, although fast it lacked the manageability of the older Bf-109E "Emil" and Bf-109F "Friedrich" which had both been superb dogfighters. Although the Messerschmitt Bf-109g variant fighters were primarily operated by the German Luftwaffe, 162 aircraft were operated by the Finnish Air Force from 1943 until 1954 when they were replaced with jet fighters, a further 14 Messerschmitt Bf-109g's were operated by the Swiss Air Force until 1946. After WW2 the The Yugoslav Air Force operated various variants of the Messerschmitt Bf-109g until may 1952. |
