But to be correct indeed both Poland and Croatia have same problem, while Poland navy slowly dissapearing, i dont think your government will have those Perries for long in service, but what will replace them, probably nothing.
Aye, they are a really old ships ... there was some plans of refit but they abandon it some time ago, thanks Gods for that. In year or two they will be mothballed.
Croatia don't have submarines, maybe one or two Todaro class would be a good force multiplier for your future navy ?
