In 2004 Croatia joined the NATO and the Navy was restructured in the process. In addition to that, in 2007 it was reorganized by dividing the personnel and vessels with newly founded Coast Guard, which remained a part of the Navy. Two former "Helsinki" class missile boats, FNS "Oulu" and FNS "Kotka", were acquired from Finland. They were renamed "Vukovar" and "Dubrovnik" respectively (both cities were almost completely destroyed by Serbian and Montenegro shelling during the Croatian war of independence), and entered service in December, 2008. They were acquired along with a considerable amount of spare parts (most notably three MTU engines - to be installed on "Kralj" class vesselshomeland war) due to a severe shortage of vessels at present. The price of these ships was €9 million and is considered rather symbolic, mostly because it was a part of the offset deal for the previous Croatian acquisition of Patria AMV armoured vehicles. The ships reached their full operational capability in June, 2009. The 2015 Strategic Defence Review envisages an overhaul and upgrade suitable for 'interception duties' to be completed in 2020. A revised out-of-service date is not known.
