The Kralj class (English: King) is a class of two missile boats, 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.
means "king" in Croatian - both vessels are named after historic kings of Croatia.
The Kralj class was developed by the Brodarski institut (BI) from Zagreb for the Yugoslav Navy as a successor to the Končar-class missile boats. The project was started during the 1980s but was reported as suspended in 1989 only to be restarted again in 1991. The first ship in the new class was to have a pennant number RTOP-501 and named Sergej Mašera after Sergej Mašera, an officer of the Royal Yugoslav Navy who died preventing the destroyer Zagreb from falling in Italian hands during Axis invasion of Yugoslavia. The new class was also referred to as the Kobra class or Type 400 in some sources.
Compared to the earlier Končar class, the new class was to have a longer hull and an all-diesel propulsion unlike the Končars which were equipped with a CODAG type of propulsion. The new class was also to be the first in Yugoslav service to be equipped with Swedish RBS-15 anti-ship missiles which were acquired in 1988 and 1989. At the start of the Croatian War of Independence, the first ship in the class was nearing completion at the Kraljevica Shipyard. The unfinished ship was captured by Croatian forces and was subsequently commissioned with the Croatian Navy as Kralj Petar Krešimir IV. (RTOP-11). A second, slightly modified ship was laid down by Croatia during the 1990s and commissioned in the early 2000s as Kralj Dmitar Zvonimir (RTOP-12).
