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 (also OF-1a), the next higher rank (comparable to Oberleutnant zur See). A Korvettenleutnant wore 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 (German: Korvette), frigate (German: Fregatte), and to ship of the line (German: Linienschiff). In the Austro-Hungarian Navy the appropriate rank designations were derived as follows.
- Korvettenkapitän OF-3 (equivalent: to Heer Major)
- Fregattenkapitän OF-4 (equivalent: to Heer Oberstleutnant)
- Linienschiffskapitän OF5; (equivalent: to deutsche Marine Kapitän zur See / Heer Oberst)
According to that systematic the rank designations to subaltern – or junior officers were derived as follows:
- Korvettenleutnant OF-1b (equivalent to deutsche Marine Leutnant zur See Heer: Leutnant)
- Fregattenleutnant OF-1a (equivalent to deutsche Marine Oberleutnant zur See / Heer: Oberleutnant)
- Linienschiffsleutnant OF-2 (equivalent to deutsche Marine Kapitänleutnant / Heer:Hauptmann)
