Rolls-Royce in Friedrichshafen is currently building mtu propulsion engines and marine gensets for the propulsion and power supply of the first of three new Miecznik multipurpose frigates for the Polish Navy. Four mtu main propulsion engines of type 20V8000 with 8,200 kW each and four mtu on-board generators of type 12V4000 with 1,650 kW mechanical power each will be installed on each ship.
“This order as part of our strategic initiative in the government business not only further consolidates our strong position in the market for propulsion systems for very fast ships. With these state-of-the-art systems, we are also supporting our NATOpartner Poland, with whom we have a long-standing partnership,” said Paul Röck, Government Business Sales Director for EMEA and Latin America at Rolls-Royce Power Systems. https://militaeraktuell.at/rumaenien-quantum-systems-liefert-vector-drohnen/ 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 patrol to high-speed operation at over 20 knots (37 km/h) with all four engines. At a cruising speed of 12 knots (around 22 km/h), the Miecznik-class vessels have a range of around 8,000 nautical miles (almost 15,000 kilometers). The four mtu on-board power generators supply the electrical power grid for ship and mission operations independently of the propulsion engines. The frigates are equipped with weapons 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 class, which is based on the British Arrowhead 140 concept, is currently being built at the state-owned PGZ shipyard (Polska Grupa Zbrojeniowa, Polish Procurement Agency) 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.
