FS2004/FSX Bf 109E 7. In late 1938, the Bf 109E entered production. It was the standard Luftwaffe fighter in the first years of WW2. The Bf 109 (designed by Willy Messerschmitt) and the later variants were some of the greatest fighter aircraft of the war. They are certainly the most famous of all German aircraft ever built. Normal and trop variants included. Gmax model by A.F. Scrub.
