Kormoran II-class

The Kormoran II class is a series of mine countermeasures vessels designed and built entirely in Poland by Remontowa Shipbuilding in Gdańsk for the Polish Navy — the first warship class completely designed and built in Poland in 23 years. The contract for one prototype and two serial units was signed on 23 September 2013. The lead ship ORP Kormoran was laid down on 23 September 2014, launched on 4 September 2015 in the presence of Prime Minister Ewa Kopacz, and commissioned on 28 November 2017.

The 58.5-meter hull is built from austenitic stainless steel, chosen for its very low magnetic permeability and corrosion resistance, reducing the ship's detectability. The hull and superstructure shapes are optimized to minimize radar cross-section. The structure consists of nine watertight compartments divided into 33 sections, rated at L-3 ice class. Propulsion is provided by two MTU diesel engines driving two Voith-Schneider cycloidal propellers, supplemented by a Schottel bow thruster, enabling speeds of 15 knots and a range of over 2,500 nautical miles. The ship can operate with a standard crew of 45 with accommodations for 7 additional personnel, and is NBC-hardened.

Mine countermeasures equipment includes Double Eagle Mk.III and Hugin 1000MR unmanned underwater vehicles, a Morświn ROV, SHL-101 TM keel sonar, and SHL-300 self-propelled sonar. Armament comprises a ZU-23-2MR Wróbel II 23mm autocannon (to be replaced by a 35mm OSU-35K system), three 12.7mm machine guns, and Grom MANPADS. Poland operates the third-largest mine warfare fleet in the world, and the Kormoran II class is central to its naval modernization.
