Another attempt was made by the military team of Luftwaffen SV Straubing, which played in the Gauliga Südbayern from 1942 to 1944.
The resulting club, TSV Straubing, formed in 1945 out of a merger of TV Jahn and FC, first appeared in the upper reaches of Bavarian football in 1946, when a regional Lower Bavaria title earned it promotion to the Landesliga Bayern (II).
In 1948, when the league was again reduced to one single division, Straubing missed out on direct qualification, coming seventh when a sixth place was needed.
The club was however offered a second chance, having to play the seventh placed team from the north and beating TSV 04 Schwabach 1–0 and thereby securing a spot for the next Landesliga season after all.
[4] In 1952–53, it came closer to relegation trouble, finishing eleventh; the next year a 13th place and a gap of only four points saw the club's worst season in the league yet.
[7] The 1960–61 season was to be Straubings last as a second division side, it came last in the league and was narrowly relegated, one point shy of a non-relegation spot.
[13] Straubing came second in the Landesliga in 1970–71 but only the champions were promoted in this era and the club's fortunes in the league became a mixed bag after this, a good season followed by an average one.
In 1976–77, another second place, two points behind champions FC Herzogenaurach, proved again not enough and in 1979 the club suffered relegation to the Bezirksliga instead.
[14] The club finally returned to what was now the Amateur Oberliga Bayern in 1982, taking out the league title in the Landesliga.
