Corvette captain

Corvette captain is a rank in many European and Latin American navies which theoretically corresponds to command of a corvette (small warship). The equivalent rank is lieutenant commander in the Royal Navy and other Commonwealth navies, the United States Navy, and the Royal Canadian Navy – a bilingual country which actually uses the term capitaine de corvette (capc) for the rank of lieutenant-commander when written or spoken in French.

Notable users of the rank of corvette captain in Europe include the navies of France, Germany, Italy, Spain, and Croatia. Other users include many Latin American countries.

While the NATO rank code is OF-3, the official translation of the rank as per NATO STANAG 2116 varies between "commander junior grade" and "commander" (with the next senior rank being translated as "commander senior grade"). Some NATO members class their corvette captains as OF-4 when they are serving afloat.

Germany
