The Fw 190 A-4 was an updated version of the German single-engine fighter, the Fw 190. The A-4 differed from the A-3 in that it was equipped with a FuG 16Z radio station and an engine injection system that provided short-term power increase. Production of the Fw 190 A-4 began in July of 1942 and continued until March 1943. A tropical version was also created with filters that enabled the aircraft to operate in the Mediterranean. More than 20,000 Fw 190 A aircraft of various modifications were produced in total, including 976 Fw 190 A-4 fighters.

The Fw 190 A-4 was introduced in Update 1.43. Like the entire Fw 190 line, the Fw-190 A-4 is best suited for attacks from above and "boom & zoom" in general thanks to its good maneuverability at speeds over 750 km/h. Additionally, the fighter accelerates well in a gentle dive and maintains its speed quite well. However, it is not very maneuverable, so it is best to avoid dogfights.
