The Pohjanmaa-class corvette is a class of general-purpose surface combatants currently under development for the Finnish Navy as part of the Squadron 2020 ({{lang-fi|Laivue 2020}}) project. Together with the existing four {{sclass-|Hamina|missile boat}}s, the four new corvettes will form the backbone of the Finnish Navy from the mid-2020s onwards. They will replace seven older vessels that have been or are due to be decommissioned: the minelayer {{ship|Finnish minelayer|Pohjanmaa||2}}, two {{sclass-|Hämeenmaa|minelayer|2}}s and four {{sclass-|Rauma|missile boat|2}}s.

Naming

One of the Finnish navy's traditions has been to name its major vessels after regions in Finland. The name Pohjanmaa, which is the Finnish name for the region Ostrobothnia, has been used both by the Finnish and Swedish navies for previous ships and classes of ships, dating back to the 18th century with the first recorded vessel being Gamla Pojama, that was launched in 1760, and the last one, being the minelayer/training vessel {{ship|Finnish minelayer|Pohjanmaa||2}}, which was sold in 2016.

Construction

The development of the Pohjanmaa class started with a research and planning phase in 2008. The design phase began in 2015 and construction is scheduled to begin in 2019. The last of the four vessels is expected to achieve full operational status by 2028.[4]

The vessels are to be constructed at the Rauma Marine Constructions shipyard in Rauma, Finland. The project's objective was to enhance localization and development of warship construction industry in Finland. The Pohjanmaa class are going to be the largest naval vessels of the Finnish Navy, surpassing the {{convert|93|m|ft|adj=on|0}} long Ilmarinen and Väinämöinen.

The vessels will take over numerous roles, the training role from Hämeenmaa, the minelaying role from Pohjanmaa and the Hämeenmaas, the surface combatant role from the Raumas, as well as add extended anti-aircraft, additional anti-submarine and surveillance capabilities. The new vessels will become operational in 2022–2028.

Procurement decision postponed in March 2019

On March 18 2019 the Ministry of Defence put out a press release about the procurement decision being postponed[5] due to the resignation of the Cabinet on March 8[6] only a month and six days before Parliamentary election.

Design and description

The class incorporates some major features including an ice class 1A-design. The flight deck, with its telescopic hangar can house either helicopters or UAVs.

General characteristics and propulsion

The overall length of the Pohjanmaa-class corvettes is {{convert|105|m|abbr=on}}, and the beam spans {{convert|15|m|abbr=on}}. The ships displace about {{convert|3000|t}} at standard load and {{convert|3300|t}} when fully loaded. Each ship compliments a crew of 66–120.[7]

The corvettes are going to be armed with Bofors 57 mm guns, ESSM surface-to-air missiles, Gabriel surface-to-surface missiles, Torped 47 anti-submarine torpedoes, as well as sea mines.

The surface-to-air missile system was selected in a competition between MBDA's Sea Ceptor, the Indo-Israeli Barak 8, and the U.S. Evolved Seasparrow Missile (ESSM), with the latter being selected.[8] The missile is built by Raytheon Missile Systems and BAE Systems in Aberdeen, South Dakota, builds the 8-cell Mk 41 quad missile canisters, of which the vessels are going to be equipped with the {{convert|7.7|m|abbr=on}}-long strike-length variant. Each ship will therefore be able to carry 32 ESSM missiles.[9][10]

The anti-ship missiles were also selected in a competition between the Israeli IAI's Gabriel 5 missile[11], MBDA's Exocet MM40, the Swedish RBS-15 Mk.IV, the Norwegian Naval Strike Missile (NSM) and the U.S. RGM-84Q-4 Harpoon Block II+ ER Grade B Surface-Launched Missiles and RGM-84L-4 Harpoon Block II Grade B Surface-Launched Missiles. The Gabriel 5 was selected in 2018.

The anti-submarine torpedoes are going to be the Swedish Torped 47 design, a light-weight torpedo, optimized for Baltic Sea conditions. The Finnish navy is going to loan and train with the earlier Swedish design Torped 45 until the final delivery of the model 47.

The combat management system is going to be provided by either by Saab Electronic Defence Systems (9LV CMS), Atlas Elektronik (ANCS) or Lockheed Martin (CMS 330).

The vessels will also be able to lay sea mines, e.g. the British PM85, or the Finnish PM04 or PM16.

Ships of the class

None of the ships have been named yet, although the first one will most likely be the namesake for the Pohjanmaa class.
