 Construction of the first out of the projected 5 shore patrol vessels (additional 10 were planned for later) was scheduled to start in 2007, however due to the onset of the economic crisis the international tender for the construction of 1 + 4 vessels was published only on April 24, 2013.The tender calls for the acquisition of a total of 5 inshore patrol ships (Croatian "obalni ophodni brod", OOB) which are to be 43.5 meters long, with a displacement of roughly 220 tons and a maximum sustained speed of at least 28 knots.They are to be armed with a 30 mm Remote weapon station as their main armament along with two 12,7 mm heavy machine guns and 4 MANPADS launchers.
