At the Lora, on December 7, 2018, the ceremony was handed over and the appointment of the Newbuilding 540 - OMIŠ, a prototype of the first coastal patrol boat, agreed upon by the Ministry of Defense of the Republic of Croatia.
The boat is 43.5 m long and is equipped with a remote-controlled armed station with an automatic 30mm ball and two hand-operated 12.7m hand grenades and 4 hand-held anti-missile missile systems. The main features of the station are remote control, built-in sensor for autonomous operation, day and night operation, stabilized dome, automatic target tracking and can fire 200 pieces of ammunition per minute.
The OOB body is made of high strength steel AH36, and aluminum alloy tops. It is insulated for its instability in the event of flooding of each adjacent compartment in the hull (for example, when the two engine rooms are flooded, the ship will not sink). The ship is equipped to protect against nuclear-biological-chemical (NBK) operations with a special system for NBK filter ventilation and airtight ship work and housing.
It is also equipped with a ramp ramp and a diversified rigid hull for 6 crew members with a propulsion diesel engine that enables speeds of up to 40 knots and 60 Nm of sailing autonomy.
The ship's capacity is 16 people with a 10-day navigation autonomy. He is very capable of persecution and achieves a speed of 29 knots provided by the main engines of power 2 x 2525 kW. It has autonomy at sea for 10 days.
It is equipped with an active rocking stabilization system that enables the boat to fully operate in sea condition 4 and meet NATO's maritime afforestation criteria (STANAG 4154).
As a special feature, the optimization of ship systems is emphasized, where with a single load of fuel can sail 1000 nautical miles at a speed of 15 knots. Optimized fuel consumption due to innovative hull design and excellent navigation properties makes it very efficient to use, resulting in significant savings compared with similar ships.
