Linienschiffsleutnant

Linienschiffsleutnant (Hungarian: Sorhajóhadnagy; transl. Ship-of-the-line lieutenant) was an officer rank in the Austro-Hungarian Navy. It was equivalent to Hauptmann of the Austro-Hungarian Army, as well to Kapitänleutnant of the Imperial German Navy. Pertaining to the modern day's NATO rank code it could be comparable to OF-2.

The rank designation was used continuously in the Austria-Hungarian follow on countries Yugoslavia, Croatia, and Slovenia, as well as in the modern day's Austrian merchant navy.

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)

This sequence of ranks can be found in the today's naval forces of Croatia, and Slovenia.
