Yup if we can outfit those with new sensors and missiles then they should be serviceable. For a country with credible threats no worse than Myanmar at this time, it makes sense for volume assets. We need money for other infra.Older Type 54 eh , hmmm if the price is right I guess we could get it
For frontline assets we need better of course, like the Istanbul class.
@Michael Corleone did PLA Navy offer older 054's to us, do we know?
