This club was also in its turn lost in the aftermath of World War II when organizations across Germany, including sports and football associations, were dissolved by occupying Allied authorities.

On 11 July that year SG became part of Betriebbsportgemeinschaft Märkische Volksstimme Babelsberg, formed only months earlier on 26 May 1949.

Sport in the German Democratic Republic (Deutsche Demokratische Republik, DDR; commonly East Germany) was subject to manipulation for political purposes, and like other football clubs there, the team would undergo a number of name changes and restructurings.

The 1950–51 season was marked by the outstanding individual performance of Johannes Schöne, who scored 37 goals, a DDR-Oberliga record that was never broken.

The side made several appearances in FDGB Pokal (East German Cup) tournament play, with their best result being an advance to the semifinals in 1951.

Following German reunification in 1990 the club adopted the name SG Fortuna Babelsberg and in 1992 won promotion to the Landesliga Brandenburg (VI).
