Why the MEKO 360 is better understood as a frigate

Should the Argentine MEKO 360 ships be counted as destroyers?

They were frigates by design and wider usage, despite occasional Argentine destroyer terminology.

Design lineage and international usage matter more here than Argentina's national label. MEKO 360 ships were frigates by design and were described that way by other operators, though Argentine usage sometimes elevated them to destroyers. The inconsistency is common: similar ships may be called destroyers by one navy and frigates by another.
