armed with a Turkish made 30 mm Aselsan SMASH stabilized remote weapon station and two 12.7mm heavy machine guns along with a MANPADS launcher. The order was placed with Brodosplit in April 2015 and the keel of the first ship was laid in September of the same year. As projected, the first vessel was to enter service in the beginning of 2017, the second and third in 2017, the fourth in 2018 and the last one in 2019. Units were projected to cost around 10 million euros, respectively. The first prototype ship, OOB-31 "Omiš" was commissioned by the Croatian Navy on 7 December 2018. Four additional ships are under construction at Brodosplit shipyard as of November 2020. Previously reported plans for the purchase of 2-4 offshore patrol vessels (OPV) or corvettes have been cancelled due to budgetary constraints but the 2015 strategic defence review envisages the procurement of a second-hand OPV by 2024. Politicians and military figures continue to discuss construction of a domestic-build OPVs or surface combatants in the post-2020 time period but this is an unfunded project. The Navy commander, rear admiral Stipanović, stated in October 2016 that the introduction of a new missile system (replacing the existing RBS-15) will be planned accordingly and executed together with construction of new OPVs.

Between 1857 and 1918 an Austro-Hungarian naval academy was located in Rijeka with NCO training school in Šibenik. Royal Yugoslav Navy founded a three-year naval academy in Gruž (Dubrovnik) in 1923 (later joined by naval staff college in 1937) while a school for petty officers was opened in Šibenik. Post-WWII Yugoslav Navy set up a "Maršal Tito" naval academy in Split. After a distinct Croatian Navy was founded in 1991, naval education went through various reforms and changes. Currently officers to be commissioned into the Croatian Navy receive their undergraduate education at Croatian Military Academy in Zagreb, which also hosts staff colleges and war colleges. A specific naval education and training centre is set up in Lora naval base in Split. Croatian Military Academy and Split University as of 2016 are in the process of opening
