Ship-of-the-line lieutenant is a common naval rank, equivalent to the naval rank of lieutenant in the UK, Commonwealth and US. The name of the rank derives from the name of the largest class of warship, the ship of the line, as opposed to smaller types of warship (corvettes and frigates). The rank is lieutenant de vaisseau in French, tenente di vascello in Italian, teniente de navío in Spanish, Linienschiffsleutnant in German and sorhajóhadnagy in Hungarian. The NATO rank code is OF-2.
