By far the most widely build 109 was the G series and of the G series, the G-6 led the crowd. Those pilots who flew long enough to fly the earlier Fs always thought that the G was a bit of a step back, however, as aviation technology moved forward, so did the 109. The G-6 had several improvements over the earlier versions. First off, it had a more powerful DB-605 engine, a requirement thanks to the additional armor and equipment added to the plane. It removed the rifle calibre 7.7mm cowl machine guns and replaced them with 12.5mm guns.
It was also able to handle a wide array of weapons slung under wings and fuselage. In addition to a drop tank, the centerline rack could carry a variety of bombs. Under the wings could be installed podded 20mm guns or even 21 cm rockets. Both of those were effective against bombers, but made the already less than nimble 109 not only more sluggish, but also ate speed. As the G series was produced, even more improvements were added to the airframe including more powerful engines as well as a taller wooden tail unit and an improved Erla designed canopy section. The G-6 was also built under license by the Hungarians and exported to a variety of nations including Finland, Rumania, Switzerland, Croatia and others.
