The four main propulsion engines of the CODAD propulsion system, two per propeller, can be used flexibly in different combinations - from single engine operation for slow patrols to high-speed operation at over 20 knots (37 km/h) with all four engines. At a cruising speed of 12 knots (approx. 22 km/h), the Miecznik-class ships have a range of around 8,000 nautical miles (almost 15,000 kilometers).
The four mtu on-board power generators feed the electrical power grid for ship and mission operations independently of the propulsion engines. The frigates are equipped with weapon and mission systems to monitor and control sea areas, protect naval bases and attack surface, underwater, land and air targets.
The first ship of the Miecznik (swordfish) class, which is based on the British Arrowhead 140 concept, is currently being built at the state-owned PGZ shipyard in Gdynia. The first ship is scheduled to be launched in 2026 and commissioned in 2030, with the other two ships to be handed over to the Polish Navy by 2031.
