Fregattenleutnant
Fregattenleutnant was an officer rank in the Austro-Hungarian Navy. It was equivalent to Oberleutnant of the Austro-Hungarian Army, as well to Oberleutnant zur See of the Imperial German Navy. Pertaining to the modern day's NATO rank code it could be comparable to OF-1a.
The rank of Fregattenleutnant was superior to Korvettenleutnant and inferior to Linienschiffsleutnant. Until 1908 the rank was called Linienschiffsfähnrich.
Professional officers skipped the rank Korvettenleutnant and were directly promoted from Seefähnrich to Fregattenleutnant.
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.
According to that systematic the rank designations to subaltern – or junior officers were derived as follows:
- Korvettenleutnant OF-1b Fregattenleutnant OF-1a
- Linienschiffsleutnant OF-2
