Frigate captain

Frigate captain is a naval rank in the naval forces of several countries.

It is, usually, equivalent to the Commonwealth/US Navy rank of commander.

Countries using this rank include Argentina and Spain (capitán de fragata), France (capitaine de frégate), Belgium (fregatkapitein), Italy (capitano di fregata), Brasil and Portugal (capitão de fragata) Croatia (kapetan fregate) and Germany (Fregattenkapitän).

In the Royal Canadian Navy, capitaine de frégate is the official French language name for the rank of commander.

The NATO rank code is OF-4, the official translation for instance of the German Fregattenkapitän as well as the French capitaine de frégate into English is "commander senior grade".

The Russian/Soviet equivalent is "captain of the 2nd rank" (капитан 2-го ранга)
