Match ships to roles rather than chase a single frigate type

Would the French Gowind corvette be a good fit for Romania?

Yes for corvette duties, but a larger Type 26-derived ship would better replace the broad role of Romania's Type 22 frigates.

The Gowind is a reasonable Romanian corvette for its intended role. The harder question is replacing Romania's larger Type 22 frigates, for which a Canadian-style Type 26 is a closer fit. For the Royal Navy, Type 26 supplies high-end anti-submarine capability while Type 31 provides cheaper forward presence and Type 45 covers area air defence. The comparison argues for complementary ship types and common support arrangements instead of buying another class that duplicates an existing role.
