Corvette lieutenant
This article is about the OF-1b (junior) rank Corvette lieutenant. For the equivalent rank in the naval forces K.u.k., Croatia, Serbia, and Slovenia, see Korvettenleutnant.
Corvette lieutenant is a rank in some navies, especially those of Spain and Latin America, roughly equivalent to a Royal Navy acting sub-lieutenant or a US Navy ensign.
The rank did exist in the French Navy during the Ancien Régime, but has now been replaced with ship of the line ensign (second class) (French: enseigne de vaisseau de deuxième classe).
The NATO rank code is OF-1 (junior)
