I don't know, I think they are a Taiwanese frigate. I am not that familiar with their classes, but it doesn't seem to have the lines of the OHP class. There seems to be a different VLS array fore of the bride and something more modern in her lines. If I would venture a guess, and I will, it looks like the new Kuang Hua-V class Corvette. If so, Yuki has built them faster than in real life! Quite an impressive fleet!
