The F120 or Köln class was a six-ship class of frigates operated by the Bundesmarine. The ships of this class were the first major warships built in Germany after World War II.

They were the world's first ships to feature a combined diesel and gas propulsion system. The ships were mainly constructed for anti-submarine warfare. All of the class' ships received numerous refits during their long careers with new electronics and torpedo tubes being fitted. They were eventually replaced by Type 122 frigates in the 1980s with Braunschweig being the last to be decommissioned in 1989. Four ships of the class were sold to the Turkish Navy.
