The construction phase began on October 9, 2024, with a steel-cutting ceremony for the vessel’s hull, held in Rauma in the presence of invited guests.

Squadron 2020 involves the construction of four advanced corvettes designed to operate in the challenging conditions of the Baltic Sea. The project progresses with both construction and design efforts proceeding simultaneously. The keel for the first vessel was laid in Rauma last April, and the entire fleet is expected to be completed by 2029. The procurement is overseen by the Finnish Defence Forces' Logistics Command.

Capable of year-round operations, the corvettes will perform a range of tasks, including naval mine deployment, surface and air defense, anti-submarine warfare, securing sea lines of communication, and long-term maritime presence.

Pohjanmaa-class corvettes

These vessels aim to replace seven older ships, including minelayers and missile boats. Designed for the unique conditions of the Baltic Sea, these 114-meter-long corvettes will feature ice-strengthened hulls, allowing year-round operations in icy waters. Each ship will displace approximately 3,900 tons and be capable of speeds up to 26 knots. Their propulsion system will include a Combined Diesel-Electric and Gas (CODLAG) configuration for efficiency and reduced underwater noise, important for anti-submarine warfare.

The corvettes are equipped with advanced combat systems, including the Saab 9LV combat management system and various sensors like the Sea Giraffe 4A radar. Armaments will cover multiple domains: Gabriel V anti-ship missiles, RIM-162 ESSM Block 2 surface-to-air missiles, Torped 47 lightweight torpedoes, and naval mines. A 57mm Bofors gun will serve as the main artillery piece, and the ships will also have facilities for helicopter operations.

Mine warfare remains a priority due to Finland's strategic position in the Baltic Sea, where mine laying and countermeasures are essential for controlling vital maritime areas and securing sea lines of communication. The Navy's operational needs are shaped by Finland’s geography, particularly the complex and icy coastal environment. The ability to operate in littoral zones and protect the nation’s extensive archipelago is vital.
