Type F122 Bremen class Frigates - The last of the post war German Treaty ships

Image.png


Background

The Bremen class Frigates was a class of 8 frigates that were built by Germany from the 1979 up until 1990 with the class being made up by FGS Bremen, FGS Niedersachsen, FGS Rheinland-Pfalz, FGS Emden, FGS Köln, FGS Karlsruhe, FGS Augsburg, and FGS Lübeck. The Bremen class were designed as the successor to the Köln class frigates and like the Köln class the Bremen class was limited in their displacement by limits imposed by the Western European Union following the end of the 2nd World War. Compared to the Köln class these ships were completely different with the ships being based off the Dutch Kortenaer class though these ships used a different propulsion system and had space for operating and storing helicopters. They were armed with 1 76mm OTO Melara gun as the primary gun due to the advancements in missile capability and as such these ships were equipped with 2 4-cell harpoon missile launchers located amid ship though images exist of the ships having the numbers reduced to 3-cell launchers however these seem to have occurred due to circumstance rather than part of any refit, additionally the ships were equipped with a 8-cell sea sparrow launcher and they also came with 4 Mk-32 Mod.9 twin torpedo tubes with the tubes themselves being in fixed mount in the hull, and later on the ships would see the installation of 2 27mm MLG27 cannons as well as the installation of 2 21 cell Mk 49 missile launchers which used the RIM-116 RAM.

History

The first 4 ship of the class would be laid down in 1979 followed by another in 1980 and another in 1981 before the last 2 ships were laid down in 1987, the first 6 ships would be commissioned between 1982 to 1984 with the last two ships entering service in the late 1980’s. The lead ship Bremen would be the first to enter service and had the unique distinction of being the first German warship to use helicopters and would later undergo a unique modification from the rest of the class as her 5 bladed propellers were replaced with 7 bladed propellers which ended up increasing the ships speed. Due to the period they were designed was influenced by the Cold War as they were designed for operations to cover NATO convoys in the northern Atlantic.

During their careers the class would all be involved in similar operations as they were apart of NATO Standing Naval Forces and took part in operations off Yugoslavia in the 1990’s as apart of NATO operations and would repeatedly take part in anti piracy operations off Africa. They would also make some notable appearances as in 1989 the Niedersachsen alongside the destroyer Rommel and the supply ship Coburg visited Leningrad which was the first visit by German ships to the Soviet Union/Russia in 77 years. While in service the class would undergo various refits including the addition of new air defense systems such as the RIM-166 RAM and weapons more suited to smaller targets more suited for the anti piracy operations they found themselves in such as 12.7mm and 7.62mm machine guns and later the addition of 27mm auto cannons and over time more modern systems.

As the years went on the class would start being pulled from service in the 2010’s with 7 of the 8 ships being decommissioned between 2012 to 2019, and the last ship being Lübeck would be decommissioned in 2022 with half of the class by this point at least being sold for scrap while the other 4 were laid up in Kiel.
