Messerschmitt Bf 109 F (Friedrich) is one of the most important versions of this famous fighter. It was powered by the same engine (DB 601E) as the preceding Bf 109 E (Emil), but the airframe design differed significantly compared to its predecessor. First of all, the plane gained a more aerodynamic profile due to the new engine cowling (the engine had its own starter, which resulted in the extension of the unit), a new, more round propeller hub and rounded wing tips. In addition, supports were removed under horizontal stabilizers. The book presents color profiles of the most popular versions of the aircraft.
