Frigate captain is a naval rank in the naval forces of several countries. Corvette captain lies one level below frigate captain.
It is usually equivalent to the Commonwealth/US Navy rank of commander.
Countries using this rank include Argentina, Colombia and Spain (Spanish : capitán de fragata), France (French : capitaine de frégate), Belgium (Dutch : fregatkapitein), Italy (Italian : capitano di fregata), Brazil and Portugal (Portuguese : capitão de fragata), Croatia (Croatian : kapetan fregate) and Germany (German : 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". [1]
Fregattenkapitän is a German Navy line officer rank OF-4 equivalent to Oberstleutnant (en: Lieutenant colonel) in the German Army and German Air Force.
