The first two of the series, specifically the HMS Helsingborg and HMS Härnösand have been delivered to the Swedish Navy.
It’s not big news, but I think that the Visby’s are the coolest looking surface combatants out there.
I would note I am still dubious of the effectiveness of full up stealth on surface ships.
Between the ocean environment, and the fact that even the stealthiest ship leaves a visible wake, I’m not sure that it does much, except perhaps reducing jamming power required by a few watts.
