The Bf 109 F (Friedrich) is the successor of the E version with the same
engine in the DB 601E version - produced from the turn of 1940/1941.
However, the airframe changed the external appearance completely: a new
propeller cap was used, the front part of the fuselage was completely
changed using a more rounded engine cover and the shape of the wings was
changed from rectangular to rounded. The maximum speed at a ceiling of
6,000 m was 635 km/h. It was armed with two MG 17s and one MG 151
cannon.
The Bf 109G (Gustaw) was equipped with a new DB 605A engine, some
versions (G-1, G-3, and G-5) were equipped with a pressurized cabin. The
first examples left the belts in the spring of 1942. The armament
consists of two MG 17 rifles (starting from the G-5/6 version, the
heavier MG 131 caliber 13 mm) and one MG 151/20 cannon. The armament
could be expanded by installing additional nacelles with cannons under
the wings (modification R6) and - from the G-5 version - by replacing
the MG-151/20 cannon built in the engine block with a 30 mm MK 108.
