Korvettenleutnant
Korvettenleutnant was an officer rank in the Austro-Hungarian Navy. It was equivalent to Leutnant of the Austro-Hungarian Army, as well to Leutnant zur See of the Imperial German Navy. Pertaining to the modern day's NATO rank code it could be comparable to OF-1b.
The right to be promoted to Korvettenleutnant was limited to so-called naval reserve officers only. However, professional officers skipped that rank and were regular promote from Seefähnrich to Fregattenleutnant, the next higher rank. A Korvettenleutnant did wear the same rank insignia as a Seefähnrich.
The rank name was selected in line to the division of war ships to specific ship categories early of the 19th century, e.g. corvette, frigate, and to ship of the line. In the Austro-Hungarian Navy the appropriate rank designations were derived as follows.
- Korvettenkapitän OF-3
- Fregattenkapitän OF-4
- Linienschiffskapitän OF5;
- Korvettenleutnant OF-1b
- Fregattenleutnant OF-1a
- Linienschiffsleutnant OF-2
