The Croatian Navy is composed of classical naval forces structured into a flotilla and the Coast Guard that solely consists of ships with peacetime duties, e.g. protection of ecology, fishing, control of tankers, ballast waters, combat against terrorism, trafficking of people, narcotics, and similar.

If vessels are caught violating Croatian or international regulations and disregard warnings by the Coast Guard, Coast Guard ships and airplanes are authorized to pursue them and if necessary open fire, while taking care not to jeopardize the lives of the vessel's crew.

Under the law, the commander of the Coast Guard is a Navy officer who is appointed and relieved of duty by the President of the Republic at the government's proposal.

Besides the warships, the Coast Guard has at its disposal two Pilatus PC-9 aircraft and four Mil Mi-8 helicopters of the Croatian Air Force and Defense.

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.
