The Swedish Navy originally planned to acquire six Göteborg-class corvettes, but following the collapse of the Soviet Union in 1991, the final two were cancelled.
Two of the four corvettes built remained in service as of 2021[update]. Modified in 2019, the two vessels form the subclass Gävle class. Both vessels, HSwMS Gävle and HSwMS Sundsvall, took part in a United Nations operation off the coast of Lebanon in 2006 and 2007, following the 2006 Lebanon War.
Gävle subclass
Sundsvall and Gävle were modified in 2019–2022. After the modification, the remaining ships were given the subclass name, the Gävle class, as HSwMS Göteborg had been mothballed.[2][3] During the upgrade the corvettes received new equipment bringing them to the same standard as the Visby class, a significant step in terms of capabilities.[4]
