| Source measurement | — | The overall length of the Pohjanmaa -class corvettes is 117 metres (383 ft 10 in) and the beam 16 metres (52 ft 6 in). The maximum draught of the vessels is 5 metres (16 ft 5 in), corresponding to a displacement of about 4,300 tonnes (4,200 long tons ). With these dimensions, the multi-role corvettes are the largest Finnish surface combatants since the 1930s coastal defence ships Ilmarinen and Väinämöinen . Each ship will have a complement of about 70 officers and crew.[source]Pohjanmaa-class corvette · Design / General characteristics; only the objects and conditions stated in this passage The Pohjanmaa class features a combined diesel-electric and gas (CODLAG) propulsion system with a total output of 28 megawatts (38,000 hp ). During normal operations, the ships' twin ice-strengthened controllable pitch propellers are driven by electric propulsion motors . Electrical power is generated by four 12-cylinder MAN 12V175D diesel generating sets , two of which are mounted on resilient foundations within soundproof enclosures to reduce noise and vibration during anti-submarine warfare operations.[source]Pohjanmaa-class corvette · Design / General characteristics; only the objects and conditions stated in this passage For high-speed operations, a single General Electric LM2500 gas turbine driving both propeller shafts via a common gearbox provides a maximum speed in excess of 26 knots (48 km/h; 30 mph). For low-speed manoeuvring, the ships are fitted with two bow thrusters .[source]Pohjanmaa-class corvette · Design / General characteristics; only the objects and conditions stated in this passage Pohjanmaa -class corvettes are equipped with a dual-purpose naval gun , surface-to-surface missiles , surface-to-air missiles , anti-submarine torpedoes , naval mines , close-in weapon systems, and decoy launchers. The forward-mounted Bofors 57 mm Mk3 dual-purpose main gun is reused from the Hamina -class missile boats . In addition, each corvette is fitted with two Saab Trackfire remote controlled weapon stations for close-range defence and four Rheinmetall Multi Ammunition Softkill System (MASS) decoy launchers.[source]Pohjanmaa-class corvette · Design / Armament; only the objects and conditions stated in this passage While the Finnish Navy and the Ministry of Defence officially classify the new vessels as multi-role corvettes, several commentators have argued that, based on their displacement of about 4,300 tonnes (4,200 long tons), the ships more closely correspond to frigates . Following the award of the construction contract in September 2019, Member of Parliament Johannes Yrttiaho ( Left Alliance ) submitted a written question to the Parliament of Finland concerning, among other issues, the classification of the vessels.[source]Pohjanmaa-class corvette · Criticism / Classification; only the objects and conditions stated in this passage Since the early 2000s, the Finnish Navy's surface combatant fleet has consisted primarily of fast attack craft with displacements of about 250 to 300 tonnes (250 to 300 long tons). Until the introduction of the Pohjanmaa class, the largest surface combatants in Finnish service are the two 1,450-tonne Hämeenmaa -class minelayers .[source]Pohjanmaa-class corvette · Criticism / Size; only the objects and conditions stated in this passage |
