I know this one, but I cannot recall its name (I have that on a book at my flat)
It was Italian Ficanteri yards test FAC/ligth corvette Seattia or something like...
Yeah I can give you that. It's CP901 Saettia coast guard cutter. I don't know the details but I think it was majorly rebuilt as a demonstration FAC with new powerplant, reduced superstructure and weapons.
