| Developed from the V10 and V13 prototypes, the "Dora" was the standard version of the Bf 109 in service with the Luftwaffe during the period just before World War II. Despite this, the type saw only limited service during the war, as all of the 235 Doras still in service at the beginning of the Polish campaign were rapidly taken out of service and replaced by the Bf 109E, except in some night fighter units, where some examples were used into early 1940. Variants included D-0 and D-1 Models, both with a Junkers Jumo 210D engine and armed with two wing-mounted and two nose-mounted 7.92 mm MG 17s. The D-2 was an experimental version with an engine mounted machine gun but this installation failed again. The D-3 was similar to the C-3 with two 20 mm MG FFsin the wings. A total of 647 Bf 109D of all versions were built by Focke-Wulf, Erla, Fieseler, Arado and AGO. Messerschmitt is listed as having only four Bf 109D produced, probably the D-0 preproduction series with the serial production transferred to license man |
