Kralj-class fast attack craft

The Kralj class is a class of two fast attack craft, one of which was on order for the SFR Yugoslav Navy and one of which, following the break-up of Yugoslavia, was built for the Croatian Navy. As of 2009 both vessels remain in service. It is an upgraded version of the Rade Končar missile boat class and is 8.5 meters longer. Kralj Petar Krešimir IV and its sister ship Kralj Dmitar Zvonimir are the only ships in their class. A potential third ship was under consideration in 1999, but the ship was never commissioned due to budget restraints.

Kralj means "king" in Croatian - both vessels are named after kings of Croatia.
