Finland’s Rauma Marine Constructions (RMC) laid the keel for the Finnish Navy’s third Pohjanmaa-class corvette and started construction of its fourth of the class in mid-January.
The first corvette, FNS Pohjanmaa, is at the outfitting phase after its launch in May 2025. The second vessel is nearing hull completion and readying for floating out later in 2026.
RMC has had to invest significantly to produce the vessels – they are the first to be built in Finland since the last Hamina-class fast attack missile craft was handed over in 2006.
“We have industrialised our procedures and construction processes to meet the requirements of our clients’ demanding projects,” said Mika Nieminen, CEO and president of RMC.
The Finnish Navy’s Squadron 2020 project, under which the corvettes are being built, provides 3,600 person-years of direct employment with a budgeted value of EUR1.2 billion (USD1.4 billion). RMC will hire 100 more staff, increasing its workforce by 25% due to the workload.
The Pohjanmaa-class corvettes have a length of 117 m, a beam of 16.5 m, a draught of 5 m, and weigh 4,369 tonnes. A crew and onboard compliment of 70 can be increased to 120 if the situation demands.
The vessels’ ice class 1A will ensure year-round operations. A top speed of 26 kt (48 km/h/30 mph) is supplied by a GE LM2500 gas turbine and four MAN 12V175D engines. Combined diesel–electric and gas (CODLAG) propulsion totals 28 MW (38,000 hp) going to two shafts with two controllable pitch propellers (CPPs).
