Paper fleet sunk

The KÖLN class was followed in the German Navy by the BREMEN class, also known as class 120 and 122. But where was the frigate 121?

The navy decommissioned the last of its eight highly successful Class 122 (BREMEN-class) workhorses at the end of 2022. The four Class 123 frigates (BRANDENBURG class) are being modernised, the three Class 124 frigates (SACHSEN class) are being battled against obsolescence, the four Class 125 frigates (BADEN-WÜRTTEMBERG class) are currently being commissioned, four Class 126 frigates have been ordered and five to six Class 127 frigates are currently being planned for the influx in the late 1930s.
