Different Destroyer Classes with the same name

Apparently, the United States Navy's two different versions of the Farragut-class destroyers were not the only instance of a ship class having the same name. Sweden and France have already done that with their submarine classes, as well as Britain with their battleship classes, and Italy with their destroyer classes as well. In fact, Sweden had two different versions of the Hajen-class submarine as well as two different versions of the Draken-class submarine that they had to name the two different Hajen-classes as the Hajen II-class and Hajen III-class, and the two Draken-classes were known as the Draken I-class and Draken II-class. As for why there was no Hajen I-class submarine, that's because the first HSwMS Hajen was actually an individual submarine. For the French submarine classes, two of their submarine classes had their lead ship named "Le Redoutable". In the case of British battleship classes having the same name, there were two battleship classes named in honor of King George V. As for the case of two different Italian destroyer classes having the same name, that was already done when the Italian Navy had two different versions of the Audace-class destroyers.
