Germany
Fregattenkapitän, short: FKpt / in lists: FK, is the middle Senior officer rank (German: Stabsoffizier Rang) in the German Navy.
It is the equivalent of frigate captain or commander in other navies, and the equivalent of Oberstleutnant in the German army and air force.
Address
In line with ZDv 10/8, the official manner of formally addressing military personnel holding the rank of Fregattenkapitän (OF-4) is "Herr/Frau Fregattenkapitän". However, following German naval tradition the "Fregattenkapitän" is usually addressed as "Herr/Frau Kapitän" or in seamen's language as "Herr/Frau Kap'tän".
Rank Insignia and Rating
Rank insignia Fregattenkapitän, worn on the sleeves and shoulders, are one five-pointed star above three stripes and a half stripe between stripe two and one (or rings on sleeves; without the star when rank loops are worn).
The rank is rated OF-4 in NATO, and is equivalent to Oberstleutnant in Heer, and Luftwaffe. It is domiciled at the A14 and A15 pay scale of the Federal Ministry of Defence and is senior to the rank of Korvettenkapitän (NATO OF-3 - Commander Junior Grade).
Whereas the equivalent ranks (with the same insignia stripes) in Belgium and Denmark are NATO-translated as Commander Senior Grade, the German equivalent is simply termed Commander.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 25, 2025. The linked authority identifier is Q22815070. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
